Iron Man's armor

Iron Man's armor is a fictional powered exoskeleton worn by the comic book character Tony Stark when he assumes the superhero identity of Iron Man. The first armor (which in the story, was created by Stark and Ho Yinsen), was designed by artists Don Heck and Jack Kirby, and first appeared, along with Tony Stark, in Tales of Suspense #39 (March 1963).

The appearance of Stark's armor has radically changed over the years, either as a result of modifications made by Stark or specialized armors created for specific situations.

Overview
Though Stark's wide array of armors have many different abilities, they are alike in that they are made of incredibly strong fictional materials bolstered by a force field. Every suit has a self-contained environment, assorted onboard weapons systems, enhanced strength, flight, and various communications arrays and sensors (such as radar and radio). Furthermore, they typically have multiple power sources including a secondary solar energy collection function in the event that conventional recharging methods are unavailable. Older versions of the armor could also fold virtually flat, allowing Stark to store them in his bullet-proof briefcase.

The defining abilities of Stark's armor are the jets situated in the boots and the repulsors situated in the gauntlets. The repulsors originated as a hand attachment, but have since become the armor's most important standard armament. They have been referred to as being magnetic, a blast of charged particles, and as a force beam. In the 2008 movie, the repulsors are a form of propulsion and (as hand units) steering jet, though they can be used offensively. A later variation on this is the Pulse Bolts, bolts of concussive energy that actually gain energy the further they have to travel, up to a limit of roughly three football fields (about 329 meters).

Another defining trait is the chest-mounted "uni-beam", also known as the variobeam, and tri-beam (in the 2008 film, Tony commands J.A.R.V.I.S. to divert power to his "chest RT," or chest repulsor transmitter). Originally a spotlight and "proton beam," it has grown to accommodate a number of other weapons, primarily light and force-based.

Construction
Contrary to its appearance, most of Stark's armors are not rigid metal suits, like a medieval knight's. His standard armor suit consists of approximately two million grain-of-sand-sized discrete units, which are shaped to have as large a surface as possible to optimize their effectiveness. The basis of the suit's structural integrity is the powerful force field which permeates the armor's "cells," as well as the whole configuration when active. Each of the "cells" is a tiny unit in its own right, contributing energy and computing power to the entire armor; this is also why the suit can remain functional even after having sustained considerable damage. The basic principle of the suit is holistic; each part contains the whole, as it were. When inactive, the entire suit can collapse on the microscopic level, the cells "folding" in on themselves to take up a smaller volume, like a three-dimensional accordion pleat.

While Tony Stark designs every aspect of the armor, the complexity of the design requires that production be entirely automated. Each cell is constructed by using specialized bacteria — the bacteria consume minute amounts of specific metals, arrange themselves on pre-tagged areas on the "chip wafer", then die, leaving a very small amount of iron, or gold, or gallium-arsenide. This method allows great precision in determining the thickness of circuitry.

All the details of the armor's construction listed above are laid out in the Iron Manual. However, some armor which appeared after publication of the Iron Manual may well use entirely different methods of construction.

Iron Man Armor MK I (Grey)
Stark's grey armor was the first iron man armor he built and (in retrospect) a prototype for the later models. It was built around an iron chest plate designed to prevent the piece of shrapnel he received in Vietnam from traveling to his heart and killing him. The armor, made from ordinary iron, provided protection from physical attacks, small arms, fire, extreme temperatures, some forms of energy, and acid. Powered by flat linear armature DC motors (rechargeable via any electrical outlet), the exoskeleton boosted the strength of the wearer by about 10 times, and employed negative feedback for motion sensing. Air pressure jets allowed for extended jumps (but not true flight) and removable suction cups allowed the wearer to cling to walls and ceilings. Weaponry included a chest-mounted monobeam (proton beam generator; useful range was only a few yards), a miniature hacksaw that could be attached to the gauntlet's fingertip, and magnetic turbo-insulators that allowed Stark to magnetically deflect metal projectiles or bring metal objects to him. Sensors consisted of a short-wave radio. All of the armor's devices and functions were manually controlled by the wearer. Stark used it to escape terrorists in Vietnam who were holding him hostage. He constructed at least one updated, form-fitting (although still rigid) version upon his return to the United States.
 * First Appearance: Tales of Suspense #39 (March 1963)

Iron Man Armor MK II (Golden Avenger)


In order to make this armor - which originally was gun-metal grey, like the original - less frightening to the general public, Stark created a gold-colored version with a wide array of improvements over the original. The new armor used the three dimensional, collapsible micro-structure now common in Stark's suits, so that it could be folded up and stored in his briefcase while inactive. The chest-plate was streamlined so that it could be worn under normal clothing without being noticeable. The suit had a semi-rigid interior with 3D knitted metallic exterior of a lightweight iron alloy, providing the same protection as his old suit did. This was also the first suit to be equipped with a force field generator. Power was still provided by flat linear armature DC motors, now rechargeable via solar recharger as well as electrical outlets, and motion sensing was still provided by negative feedback. The Mk II air pressure boot-jets provided limited flight; steering while flying was accomplished by bodily movement. Weaponry consisted of the chest-mounted Mk II Monobeam (usable as either a concussive force beam or a heat beam), a sledgehammer, hacksaws extending from the fingertips, hand drills, electromagnets allowing him to pull things to him and push them away, and an electrical field generator. Communications and sensor arrays consisted of a loudspeaker, short-wave two-way radio, radar, and a tape recorder. When one iteration of this particular armor was partially destroyed by the Melter, a super-villain who could dissolve iron and iron alloys with a special ray, Stark built an exact copy using aluminum instead of iron, which was unaffected by the Melter's ability to dissolve iron.
 * First Appearance: Tales of Suspense #40 (April 1963)

Iron Man Armor MK III (original red and gold)
Stark's trademark red and gold armor arose from a battle with a villain named Mr. Doll, who could control the gold armor through a replica figurine. To circumvent the villain's ability, Stark withdrew and constructed a new suit with a significantly different look and a lighter build- thus allowing him to devote less of his own strength to moving the armor and more to fighting Mr. Doll's influence, resulting in the streamlined red and gold suit.
 * First Appearance: Tales of Suspense #48 (December 1963)

The red and gold armor was composed of an ultra-fine 3-D knit alloy and incorporated motors into the knitting to allow full mobility. While it ran on the same type of power, the power consumption was much more efficient. The boot jets were upgraded to chemically fueled thrusters, which provided a much faster flight speed. Weaponry consisted of the chest-mounted Mk II Monobeam (useful range was still only several yards), repulsor rays, a proton gun, and powerful electromagnets to pull metal objects to him or repel/push them away. Communications and sensors consisted of a short-wave radio. Other features included an image reproducer and collapsible roller skates. Most functions were controlled by miniature electronic switches mounted on the insides of various pieces of the armor such as the helmet and the gloves; by pressing various combinations of them, different systems were engaged. The switches in the helmet were enabled by the wearer's tongue; other functions were utilized with wrist-mounted controls.

Beyond these features, Stark also occasionally experimented with cosmetic modifications such as adding a nose indentation on his faceplate, or rimming the face-plate with rivets.

While the appearance of the armor changed only slightly, over the years its technology improved by leaps and bounds, resulting in vastly increased strength, speed, and firepower. Control of the armor was slowly shifted from motion feedback and internal buttons to cybernetic controls, which could sense and interpret the wearer's own brainwaves and respond accordingly. The pacemaker function of the chestplate was also eventually abandoned, as Stark's heart was repaired using artificial tissue.

It is hinted that Tony Stark based the new cosmetic improvement on a childhood fantasy, as the red and gold color scheme came from his elementary school's colors, and the whole "Iron Man" motif from the eponymous song by Black Sabbath.

Iron Man Armor MK V (classic red and gold)
Armor structure was improved with 3D knitting. In addition, a force-field helped keep the armor rigid. The armor used solar power and integrated micro-circuitry. A thermocouple was used to handle extreme temperature and convert it to usable power, but it could be overloaded. Repulsors were standard weaponry. The variobeam/uni-beam was capable of various effects. A tractor beam could be used to pull or throw objects. The most recent version of the armor was able to use pulse bolts. Gyro-stabilizers were used in the boot jets. Power pods were capable of various functions such as boosting other systems or being set to detonate. ECM jamming was used to evade detection. A hologram emitter created multiple images to make the armor harder to target. In addition to the sonic emitter, a voice distorter helped protect Stark's identity and could also be used to duplicate sounds. The armor could travel underground. Freon could be emitted and a built-in fire extinguisher handled internal and external fire. Finger lasers and a "sabresaw" were available for cutting through objects. Life support was improved; the pacemaker was no longer needed after successful heart surgery. A slave circuit was added to control older suits after the incident with Weasel Willis. However, this was a weakness when Midas attempted to gain control of the armors. Sensors were upgraded with a full-band transceiver, infrared, and a 'life detector' that was keyed to several important personnel.
 * First Appearance: Iron Man (vol. 1) #85 (April 1976)

Although he has since developed more advanced armors, Stark has returned to this armor when situations have forced him to discard his latest armors due to serious damage and he lacks the time, resources or inclination to create a replacement immediately. Examples of this include when he was forced to destroy his sentient armor and feared designing a more advanced suit in case he repeated the accident that gave his previous armor sentience, when his Extremis abilities were deactivated and he was investigating strange disappearances, and when Norman Osborn led the Dark Avengers in an invasion of Asgard when Stark was trying to update himself following his mental "reboot" and the loss of Extremis in the "Stark Disassembled" storyline.

Armors of the 1980s
During this period, Stark came to realize there were several situations where his regular model armor, while functional in most environments or situations when necessary, could not perform optimally. In response, Stark began to develop numerous specialized suits for special missions.

Space Armor MK I
While based on the same design principles, this suit's matrix was formed non-collapsible to increase its protection from the rigors of deep space; also, its specialized nature made collapsibility unnecessary. Power was provided by a Mk IV micro-nuclear supply pack, supplemented by solar power converters. Systems were controlled via a cybernetic interface, though it proved to be overly sensitive; when Stark first used the armor he had difficulty triggering the appropriate command to activate the feature he wanted. The suit was designed for extended time outside of the atmosphere, up to two days in orbit (food and catheterization capable). The life support, boot jets and altitude maneuvering were powered by an on-board supply of liquid oxygen. Weaponry consisted of palm-mounted third-generation Repulsors (electron beams which require laser ionized path of air to travel through the atmosphere; the beam is moderated using a pulsing beam and early form of adaptive optics; objects are jolted away from the beam path by the combination of ionized air and the accelerated neutron beam) and a chest-mounted Unibeam (a variable intensity light source usable as a spotlight or a laser; the pentagon shape of the emitter allowed for more accurate laser pulsing while in an atmosphere), and epaulet-mounted concussion-burst cannons. Sensors consisted of radar, sonar, infrared scanners, and radio. Additional features included ECM against radar and sonar, and the fully articulated hands could be fired out on retractable cables for use as long-range grapples. The most obvious feature on this special armor was its ability to attain escape velocity without aid of an external thruster, unique to this Iron Man version; however, the nuclear jets which allowed this made the suit bulky, heavy and awkward in Earth's gravity. The dangers inherent in an atomic-energy based propulsion system of such immense power seem to have driven Tony Stark to build the thruster unit which he has been using ever since.
 * First Appearance: Iron Man (vol. 1) #142 (January 1981)

Iron Man Armor Model 07 (Stealth Armor MK I)
The Stealth armor is another of the specialized suits of armor developed by Tony Stark for specific missions, similar to the Space Armor; indeed, its creation was inspired due to him being tracked by radar during his use of the Space Armor. The Stealth Armor was designed using current "stealth" technology to allow Iron Man to foil detection devices and slip unknown in and out of restricted areas. This sleek, jet black suit (composed of impact resistant carbon-composites overlaid on top of layered "flex-metal" which can condense itself like a 3-dimensional accordion pleat) was a polarized metal mesh armor that uses every bit of space for detection and evasion components, and therefore was originally designed with no weapons. A bubble-shaped "backpack" was also incorporated into the armor to expand the space available for the stealth systems. Most of this armor used solar power to charge the batteries and run most of the integrated circuitry, though the pods on the sides were batteries that could maintain the suit's functions for a short time. It was able to recharge itself from electrical sources, a thermocouple to siphon power from extreme heat or cold, and solar power. The suit utilized force field technology to render Iron Man electronically invisible- a layer of low density plasma would be held in place by a focused magnetic field, and the tripole waveform reflected radar, along with a wave modifier that bent the radar around it. To quash any detectable infrared signature, the armor's boot-jet exhaust was "washed" by bursts of super-cooled air. The micro-turbines on his jet boots possess assisted air liquification devices; rings of liquid nitrogen.
 * First Appearance: Iron Man (vol. 1) #152 (November 1981)

Iron Man Armor MK VI (Recovery armor)
After climbing back out of the gutter where he had landed after Obadiah Stane's psychological attack had devastated him, Tony Stark started to construct a very basic armor out of spare parts he asked as payment from the companies he advised. More symbolic than anything, this armor had a strong resemblance to the very first, gray armor. While far more advanced than most earlier armors, it was inferior to the regular model Jim Rhodes was using at the time. It was eventually and unceremoniously destroyed by one of Stane's mechanical pawns. Nevertheless, it served to channel Stark's emotional distress into creative paths and paved the way for the armor that came next.
 * First Appearance: Iron Man (vol. 1) #191 (February 1985)

Iron Man Armor MK VII (Silver Centurion)
Stark began creating the Silver Centurion armor as a method of working out ideas and experimenting. The S-circuit, which uses its energy more efficiently, is an example of the breakthrough developed by Stark, using the armor as a model. With the destruction of Circuits Maximus by Obadiah Stane, Stark donned the newest set of armor to battle the foe that stripped him of his business, his friends, and almost his life. The battle with Stane was the first field test of this armor, and resulted in the defeat of Stane and the destruction of Stane International.
 * First Appearance: Iron Man (vol. 1) #200 (November 1985)

The suit had a rigid interior and a 3-D knitted metallic exterior, providing protection from physical attacks as well as acid, heat, cold, most forms of energy, radiation, and electricity. A 3-D knitting pattern on a submolecular construction level gave the armor itself more strength, while allowing for the most comfortable suit interior. By expanding the field that keeps the armor rigid, the armor could encase itself in a protective force field that was effective against most forms of attack; Stark could also use this field to polarize the armor to either attract or repulse other items via magnetic polarity.

Most of this armor used solar power to charge the batteries and run most of the integrated circuitry, though the pods on the sides were batteries that could maintain the suit's functions for a short time. It was also able to recharge itself from electrical sources, a thermocouple to siphon power from extreme heat or cold. Flight was accomplished via Mk IV boot-jets (which incorporated high-speed duo-source turbines), supplemented by a booster pack that enabled the armor to attain speeds up to 750 mi/h in the air and 180 mi/h in the water.

Weaponry consisted of a chest-mounted Mk III Unibeam (search light, heat beams, tractor beam, laser beam, and ultraviolet light beam), palm-mounted Mk III Repulsors (laser-guided particle beam emitters), pulse bolts (slow-moving high energy plasma discharge "torpedoes" that build in intensity as they travel through the atmosphere, picking up static and ambient energy and thus doing more damage the farther they travel), and a sonic emitter (generating high-frequency sound waves).

Sensors consisted of a full band audiovisual transceiver simultaneous images of the armor. It could also be used to generate a "chameleon field" around itself; the computer in the armor would analyze its surroundings and generate a hologram to make it blend in with the surroundings making it effectively invisible visually and to cameras. Unfortunately, the "chameleon effect" module interfered with the cybernetic controls of the armor, generating feedback and resulting in massive headaches for Stark.

The Silver Centurion armor- or a copy of it, given that the original was destroyed towards the conclusion of the "Armor Wars", was used by Tony Stark to defeat the Mandarin, when his Extremis abilities were temporarily deactivated due to concerns regarding his mental health.

Hydro Armor
This unit was designed for salvage missions at the bottom of the deepest oceans—while Stark's conventional suits function underwater, they were noisy, inefficient, and they leaked. The exact composition is unknown; it is assumed to be composed of the same layered "flex-metal" micro-scale suit tiles fabricated by genetically engineered metal-affinity bacteria which assemble themselves in specific orderly arrays and then expire, leaving behind various metallic deposits which form all the metal shapes and micro-electronic circuits. A new aligned-crystal production process allowed the construction of a large, semi-spherical headpiece, as transparent as glass. This unit possessed several ocean-specific weapons, such as the electric field of an electric eel, a camouflage 'ink cloud' and small 'manta ray' torpedoes. It also comprised an inner "Escape Suit" that could be jettisoned from the main suit in case of emergency (this inner suit possessed a Unibeam, 2 torpedoes, and the holding bay). Functions were controlled by cybernetic interface.
 * First Appearance: Iron Man (vol. 1) #218 (May 1987)

Low Observable Armor (Stealth Armor MK II)
This armor was nearly identical to the Mk I Stealth Armor, with two additional features. The first was a camouflage effect, similar to the chameleon effect generated by the Silver Centurion armor. This suit's camouflage effect was entirely manually controlled, providing the wearer with invisibility to visual or camera detection, but only against backgrounds that are mostly of one color. The second addition were palm-mounted Mk IV Repulsors, though they only had enough energy to fire three shots at full power. The stealth systems were far more streamlined, allowing for the elimination of the "backpack" on the first model.
 * First Appearance: Iron Man (vol. 1) #229 (April 1988)

This suit was utilized by Clay Wilson to fill in for the "real" Iron Man after Tony Stark had been shot.

Iron Man Armor MK VIII (New Red and Gold)
During the Armor Wars, Iron Man found himself facing the government-sanctioned armored assassin Firepower. Against this walking, flying armored arsenal, even the Silver Centurion armor did not stand a chance, and it was destroyed. Reluctant to enter the fray again, but forced into action, Tony Stark designed a new suit, even more powerful and versatile than its predecessor, designed specifically to negate Firepower's original advantages, such as a means of disrupting Firepower's targeting systems, a gauntlet-generated energy shield, and more powerful boosters for increased speed. It made short work of Firepower, and Stark was so horrified of the destructive potential of the armor should it fall into the wrong hands, he resolved to destroy it. Fortunately, he changed his mind. The modern classic armor resembled the classic armor which had endured for many years, with some minor cosmetic changes. Its appearance changed somewhat, mainly becoming more bulky, ostensibly to increase thruster power (its massive boot-jets earning it the some-time nickname "coffeepot armor"). It was also the first armor to incorporate a beta-particle generator, radically reducing Iron Man's external power needs and boosting his offensive power.
 * First Appearance: Iron Man (vol. 1) #231 (June 1988)

Space Armor, Mark II
A new space armor design intended to function for weeks on end without maintenance, recharging or restocking of resources. It was able to evade the sophisticated sensors on Kree and Shi'ar spaceships as well as interface with their technology. It also possessed an extremely powerful self-destruct mechanism via its fusion reactor.
 * First Appearance: Iron Man (vol. 1) #278 (March 1992)

Telepresence Armor
Critically wounded by a bullet near his spine, Tony Stark was paralyzed from the waist down. After some soul-searching, he designed an armor which would enable him to walk. While his paralysis was ended by the implantation of an organic microchip, this proved only the start of his problems, as the biochip was revealed to be a parasitic life form, designed to consume his own nervous system and replace it with one that could be controlled from the outside. He now needed the support armor even more to protect himself from the people who controlled his body, since his armor cybernetically responded to his own brain. The cybernetic interface and battle computer were integrated with the Telepresence Neural Net, a more subtle armor he used to simulate his degenerating nervous system. While it was still worn as a suit of armor, the functions and muscle control were carried out by the suit, not by the wearer.
 * First Appearance: Iron Man (vol. 1) #280

War Machine Armor (Variable Threat Response Battle Suit, Mark I)
Officially known as the Variable Threat Response Battle Suit, this armor was created initially by Stark to deal with the Masters of Silence threat by using a "respond in kind" philosophy and strategy. It was designed for all-out warfare and was Stark's experiment with laser guided munitions and ballistic weaponry. Since the Masters of Silence were protected against Iron Man's usual weaponry of repulsors and unibeam, those weapons were removed from the Mark I model. The armor included several response devices such as a shoulder mounted electric minigun, shoulder mounted missile box launcher, and wrist mounted gaunlet cannons with additional weaponry such as a laser blade and flamethrower. It was not collapsible, and included far heavier carbon-composite-based armor as well as improved tactical computer systems and automatic targeting. A later version, Mark II Model JRXL-1000, was designed and built for James Rhodes, which became a full-fledged superhero identity for him as War Machine. In Mark I model, both the double-barreled cannon and the plasma blade were fixed with the flamethrower built over the plasma blade casing. In Rhodes' Mark II model, the wrist weapons became modular and the armor also included repulsor and unibeam technology. In both iterations, the shoulder mounted weapons are modular and can be removed and replaced. All further incarnations of the armor were used by Rhodes.
 * First Appearance: Iron Man (vol. 1) #281

NTU-150 Telepresence Armor
Though similar in design to both the Neo-Classic armor and its remote-controlled counterpart, the NTU-150 incorporated the new SE Telepresence technology, enabling the unit to be operated under full Virtual Control. This unit was not a wearable suit of armor; rather, it was a fully articulated device controlled by the mental impulses of the user via a remote headset apparatus. The remote headset transmitted commands to the active unit in much the same way as the human brain transmits commands to the central nervous system (in this case, it is via a subspace radio connection, lessening reaction time to almost zero). Similarly, the visual, aural, and (to a lesser degree) tactile information collected by the NTU-150 could be interpreted by the user's brain in the same way as normal sensory data. The primary difference is that the sensory data collected by the NTU-150 includes a full range of electromagnetic spectra and computer-processed data normally unavailable to humans, while the active devices contained in the unit includes not only analogues to the human body, but weaponry, data collection and processing hardware as well, all under autonomic and voluntary nervous system control. In contrast to traditional robotic devices, the NTU-150 contains no mechanical framework to mimic the action of the human body; the unit's outer shell is articulated by a multiprocessor-controlled structural integrity field which allows for a much greater range of movement.
 * First Appearance: Iron Man (vol. 1) #290 (March 1993)

Modular Armor
This unit is a drastic departure from all of the previous armors. Instead of a single cohesive unit, each piece of the armor is a stand alone subsystem that can be interchanged at will. As such, while the overall unit is still referred to as the Mark 11, the actual configuration at any given time will vary. The shell was composed of layered "flex-metal" which could condense itself like a 3-dimensional accordion pleat. Micro-scale suit tiles were fabricated by genetically engineered metal-affinity bacteria, which assembled themselves in specific orderly arrays and then expired, leaving behind various metallic deposits which form all the metal shapes and micro-electronic circuits.
 * First Appearance: Iron Man (vol. 1) #300 (January 1994)

The Modular Armor is rather well-known outside of comics due to it being the main armor in the Iron Man animated TV series and Capcom's Marvel vs. Capcom video game series.

Hulkbuster Armor (Modular Add-on)
The Hulkbuster armor is a heavy-duty exo-frame (an add-on to the Mk. XI Modular Armor) designed for maximum strength amplification at the cost of reduced versatility and mobility. As its name suggests, it was specifically designed for hand-to-hand combat with the rampaging Hulk. The armor was rated with a lift (press) capacity of 175 tons. During its maiden run, the armor enabled Stark to hold his own in sustained physical combat with the Hulk.
 * First Appearance: Iron Man (vol. 1) #304 (May 1994)

Arctic Armor
The Arctic Armor was designed to be able to withstand temperatures as low as -340 degrees, it was one of Tony's favorite armors. Very little is known about this armor; Stark used it to travel to an Arctic bunker. It was blue and silver in color, and possessed a unique hexagonal chest beam.
 * First (and only) Appearance: Iron Man (vol. 1) #318 (July 1995)

Crossing Armor
With this armor, Stark did away with the Modular Armor and constructed a version designed specifically for combat.
 * First Appearance: Iron Man (vol. 1) #319 (August 1995)

Its appearance was simpler, sporting rivets as its only decoration. Bulky gauntlets housed more powerful repulsors on top of the wrist instead of in the palm of the hand.

Retro Armor
This armor's design history is unknown; it stands out because it, out of all the other armors in the armory, was picked by "Teen Tony," a Tony Stark who had been plucked out of an alternate time stream many years in the past to help fight his present-day self.
 * First Appearance: Iron Man (vol. 1) #325 (February 1996)

Teen Tony Armor
Not a full armor, but only a chest plate to keep the young Tony’s heart beating. Was soon upgraded with a pair of gauntlets. A chestplate and gauntlets, but more powerful and with superior shielding against energy attacks. Based on the mark 2, this was the first full-body armor constructed by the young Tony Stark – out of bits and pieces cobbled together on a moment’s notice. It was created to fight the super-cold villain Frostbite and therefore particularly geared at manipulating heat and cold. Finalized armor, like a streamlined, upgraded version of the mark 3, with design elements of model 16. It only partly consisted of solid metal; parts of the limbs’ armor were holographic force-fields (which were visually indistinguishable from the original golden armor).

Prometheus Armor ("Heroes Reborn")
During the Onslaught event, Tony Stark was one of the heroes who sacrificed himself to defeat the menace, and consequently was shunted into a newly created pocket universe by reality-altering mutant Franklin Richards.
 * First Appearance: Iron Man (vol. 2) #1 (November 1996)

In the new universe, every person had a new, but complete history- including a childhood, youth and adulthood- and no memory of their original universe. So Iron Man had to be reborn- and he was, this time not as a result of a booby trap in the Far East, but a direct encounter with the newly born Incredible Hulk. His chest pierced by shrapnel from a crashed helicopter, Tony Stark had no choice but to do an experimental exoskeleton (Project: Prometheus Rising) which had cost the life of one of his closest friends before. He had to keep wearing the chest plate constantly to keep his shredded heart beating thereafter.

The paradigm of this armor was quite different from the one Iron Man had worn for years in the baseline universe, but the arrangement of weapons, and, oddly enough, the color scheme, remained similar. Its sensors seemed somewhat more advanced. It remained cloaked when not worn, but could join up with the chestplate in seconds when called.

Renaissance Armor ("Heroes Return")/Sentient armor
Fresh upon his return from the "Heroes Reborn" universe, Tony constructed this armor which served as a new beginning, combining cutting-edge technology with classic lines. The armor possessed energy-absorption strips, as well as a "horned" faceplate, reminiscent of the first red-and-gold armor, and a pentagonal chest beam. Its most useful feature was a completely self-contained life support system, allowing Tony to completely cut himself off from the outside world while relying on food pills and the armor's own internal atmosphere if he was in a hostile environment, a feature that came in particularly useful when he was abducted by the Brood to participate in a contest against other heroes, the armor's internal life support allowing Tony to escape infection by the mood-altering nanites the Brood were using to keep the heroes too aggressive to consider their situation in depth long enough to develop a means of curing his allies.
 * First Appearance: Iron Man (vol. 3) #1 (February 1998)

This armor eventually achieved sentience due to Tony downloading Jocasta into the armor- thus corrupting the usual failsafes Tony had installed to prevent such an occurrence happening as Jocasta unintentionally infected the armor with the 'Ultron Imperative', a system that would cause Ultron's creations to rebuild him if he was ever destroyed-, lightning strikes sustained during a fight with Whiplash providing the necessary 'nudge' to push the armor into full sentience based on Tony's own mind. Although the armor's new tactical abilities made it far more efficient than previous armors, able to evade attacks based on past experience with opponents, its lack of human morality caused it to kill Whiplash in its 'test drive', subsequently becoming increasingly obsessed with merging with Tony so that they would become Iron Man on a permanent basis (on a more practical note, it also suffered from a power supply problem as it ran down its batteries at a far more rapid rate due to the energy required to sustain its sentience). Although it attempted to kill Tony in a final confrontation on a deserted island, when Tony suffered a heart attack, it reverted to its default programming, sacrificing its own central power source to help sustain Tony's heart. It was later salvaged by the 'Sons of Yinsen'- a cult who followed Ho Yinsen- to use as a host for Yinsen's brain, only for Ultron to take control of the armor before it was destroyed for good.

Tony temporarily returned to a variation of the Heroes Return armor in the aftermath of Secret Invasion in Iron Man (vol. 5) #10 (April 2009).

Experimental Safe Armor
Experimental armor incorporating safe power systems, necessary when it became apparent the constant exposure to the powerful energy fields inside the Iron Man armor were harming Tony's health. Iron Man transported to the moon to help the Fantastic Four; however a malfunction caused a brief battle between Iron Man and the FF. Despite its rough, unfinished state, it still played a vital role in defeating Ronan, the Kree Supreme Accuser.
 * First Appearance: Fantastic Four (vol. 3) #15 (March 1999)

Outer Atmospheric Armor
A completely new space armor design. It requires a booster rig for takeoff, and has therefore been trimmed down to reduce weight. While it offers less protection than previous models, it is also stealthier and far more maneuverable in space, using anaerobic jets for propulsion. It contains a special compression gel to protect the wearer from G-forces, and automatically seals any leaks. To accommodate re-entry, the unit possesses a massive, expanding solar sail.
 * First Appearance: Iron Man: Bad Blood (miniseries) #4 (December 2000)

S.K.I.N. Armor
This armor's main difference from its predecessors is its sheer size; the torso and shoulders in particular are massive. Its development, starting from scratch, resulted mainly from Tony's fear that an innate factor had resulted in his previous armor developing sentience. Its appearance also differed markedly from the Sentient Armor, perhaps to make it seem as different as possible: it possessed a circular chest beam, a greatly altered overall configuration (including many "industrial-style" details such as external tubing, earning this suit the ignoble nickname "udder armor") and a restyled helmet.
 * First Appearance: Iron Man (vol. 3) #42 (July 2001) (prototype); Iron Man (vol. 3) #44 (September) (finished design)

The armor is powered by a Beta Particle Generator and solar power converters and controlled by a Cybernetic Interface and Battle Computer to enhance reactions when in combat. It can absorb directed energy attacks as well as massive non-directional energy discharges (like explosions). It also possesses a new force field.

The golden sections of Iron Man consisted of S.K.I.N (Synth-Kinetic Interface Nano-fluid), a liquid alloy that can be manipulated to conform to any desired shape. It is lightweight but has immense structural integrity, being harder than titanium and approaching low-grade adamantium. S.K.I.N. can be contracted to fit into a small container or stretched/shaped into another form. The alloy's wondrous properties were developed by Askew Technologies, and the exact elements incorporated into the S.K.I.N. remain unknown. Tony had set up the S.K.I.N. of his armor to be stored in a small container. On his command, the S.K.I.N. spilled out and assumed its default armor configuration.

The larger size of the armor accommodated storage of several new systems, including an improved sonic array, upgraded chameleon field, energy blade, missiles and even a number of grapefruit-sized, spherical drone units which could hover and fly autonomously, and serve as scouts or remote-controlled weapons.

Unfortunately, this design had to be abandoned after Ultron proved how easily he could make S.K.I.N. (or a human being it was bonded to) jump through hoops.

Stealth Armor MK III
Similar to Stark's earlier Armor, the Mark III Stealth unit was also specifically designed to combat the Black Panther's anti-metal vibranium claws – it is composed entirely of advanced composite ceramics and experimental bio-neural gel-pack circuitry, fused with a kevlar-like polymer and backed by optical fiber networks; all of which comes down to an armor which was invisible to electronic detection systems as well as the naked eye, even the Black Panther's. Although the development of Stark's new cloaking technology for the Mark 25 "S.K.I.N." armor probably rendered the Mark III unit's stealth technology obsolete, the Stealth armor is nevertheless an effective weapon against opponents such as the Black Panther and Magneto because of its plastic/ceramic design.
 * First Appearance: Black Panther (vol. 2) #44 (July 2002)

Tin Man Armor
After the S.K.I.N. fiasco, Tony once again more or less redesigned the armor from scratch. Improved scanning included GPS and a particle mist that could be used to 'mark' targets. The armor, which went through various evolutions, had originally a generally segmented, almost insect-like appearance; later, it became heavier, more industrial, and the ultimate form of this armor (through trimmed down) made Tony sigh, "It's difficult to believe I used to be able to fit this inside a briefcase".
 * First Appearance: Iron Man (vol. 3) #50 (March 2002)

Carbon dioxide provides underwater propulsion; immediate satellite uplinking even from miles underwater was possible.

Repulsors were improved with a 'crowd control' setting. The armor could also release a (tentatively called) "deflector pulse", a shaped force field blasting outward from various points on the suit. Armor could also release a devastating "blockbuster" blast utilizing uni-beam and repulsors in concert, but more potent than either.

When commanded, the armor could also adopt a hovering, non-humanoid, autonomous combat mode, equipped with energy and projectile weapons.

Thorbuster
The Thor-Buster armor was designed by Tony Stark as a precaution against Thor, in case his good deeds went bad. The power source for the armor was a mystical Asgardian crystal, originally part of a new type of power generator that Thor left Tony Stark to possibly use as a new energy source for mankind. Outwardly, it resembled the Asgardian Destroyer. It was destroyed by Thor, its power source undone.
 * First Appearance: Iron Man (vol. 3) #64 (March 2003)

Cobalt Man impostor
Used to impersonate the Cobalt Man.
 * First Appearance: Avengers/Thunderbolts #1 (May 2004)

Ablative Armor
This prototype armor possessed armor made up out of three-inch (76 mm), honeycomb-shaped tiles, piled several layers thick. Each tile was made of high-impact polymer. When one of the tiles was damaged, it popped off and the next one below it snapped into place. Furthermore, the suit used repulsor-tech force fields to position new tiles, produced in a "polymer kiln" on its back. It could also create a "storm cloud" of thousands of orbiting tiles around itself to act as "chaff". This armor was originally designed to be used in space, where micrometeoroids provided an impact-rich environment, but was ultimately used to defend against a parasitical alien life form which infected organisms and altered them to suit its needs. For optimal efficacy, the tiles were "loaded" with specialized nanobots which would turn the alien's biology against itself.
 * First Appearance: Iron Man (vol. 3) #71 (October 2003)

Iron Man Armor Model 29
Tony Stark began using this armor during the time that he served as the United States Secretary of Defense. Standard weaponry including repulsors, uni-beam and sonics. Concussion blasts were used against the Hand. Zero-point energy was used against Michael Pointer (aka The Collective). Via voice command, the armor could adopt an autonomous, robotic Battle Mode. If separated by magnetism, it could reform and return to Stark. Defensively, a repulsor shield could be extended to protect the armor and allies. Security was enhanced by upgrades to anti-tampering devices
 * First Appearance: Iron Man (vol. 3) #72 (November 2003)

Anti-Radiation Armor
The armor is designed to attract radiation into the armor where it is converted into usable power. This greatly enhances its strength. Through absorbing ambient radiation the armor is able to decontaminate irradiated areas. It also possesses repulsors and a unibeam.
 * First Appearance: Incredible Hulk (vol. 2) #72 (July 2004)

Banner's addition was "RG-27," a special compound that neutralizes gamma radiation. Since it is most effective in liquid or gas form, a series of tubes were built into the armor for irrigation. This enables the armor not only to withstand radiation, but also allows it to decontaminate areas. To expose a government conspiracy, the two faked a quarrel over some of their designs. Stark unveiled a finished version of the suit to battle the Hulk. However, Stark seemed to be acting strangely while wearing the suit. A problem with the irrigation system was discovered. The Hulk was able to help Stark shut it down before gamma poisoning set in.

High Gravity Armor
Designed to withstand high gravity environments; it was bulky, being able to survive long-term exposure to at least 50 G; the wearer had blood artificially forced to body parts which would otherwise suffer from the extreme gravity. Unfortunately, the wearer is still susceptible to nitrogen narcosis and the bends.
 * First Appearance: Iron Man (vol. 3) #83 (July 2004)

Iron Man Model 30 (Extremis Armor)
After being critically injured during a battle with a nanotech-enhanced foe, Stark injected his nervous system with a modified techno-organic virus to save his own life. This fused Stark's armor to his body, allowing him to store the inner layers of the Iron Man armor in the hollows of his bones as well as control it through direct brain impulses. The Extremis enhancement has turned Stark into a cyborg, whereby the usage of his existing lockchip (a personal area networking implement implanted in his forearm) is directly integrated into his nervous system.
 * First Appearance: Iron Man (vol. 4) #5 (March 2006)

His new armor is no longer a bulky unit which houses its own AI "response server" and miscellaneous interfaces for neural control. Instead, it is more lightweight (constructed of a pliable crystalline material with a molecular structure that can collimate into super-hard planes upon the application of an electrical field) and less complex (as it interfaces directly to Stark's brain via the Extremis-modified cybernetic connections), and has much faster response time since it effectively functions like Stark's second skin.

He is also able to remotely connect to external communications systems such as satellites, cellular phones, and computers through the PAN interconnect (that is now thought-controlled). Because the armor's operating system is now directly connected to Stark's nervous system, its response time has been significantly improved.

Another major departure from the previous armors is expansion of repulsor technology. The "repulsor flight system" provides lift (something like anti-gravity) and positive flight control (pitch, roll and yaw), while the usual rocket boots provide the armor with thrust. The same repulsor technology allows the individual pieces of the armor to levitate and assemble themselves, by modulating what Stark referred to as "vectored Repulsor fields".

Furthermore, the Extremis process has endowed Stark with a 'healing factor' and possibly even enhanced physical abilities, as he was confident enough to challenge Logan/Wolverine to a fight (and even challenging to see who's capable of recovering faster from the other's attack). It was later stated that the Extremis enhancement speeds up a person's repair process and hence the body's cells died and regenerated at a faster rate. This effectively made Tony Stark immune to cancer and gave him his 'healing factor'.

In the Iron Man: The Inevitable storyline, it was shown that it's not only Tony Stark's body and the interfacing undersheath that has self-healing properties. Even the Iron Man armor has the ability to self-heal and self-repair, presumably through the use of nanotechnology. The armor is also able to store power throughout its structure, indicating that instead of having main batteries mounted around the waist as in the older Iron Man armors, the Extremis armor incorporates distributed and decentralized energy storage.

Note: Although Extremis for reasons of simplicity is referred to as "a virus", it is not. The Extremis process involved injecting several billion microscopic nanotubes, which act as information carriers, into the brain. The brain is then partly reprogrammed; the so-called "repair center," that part of the brain which maintains an "integrity map" of the body, is told that the body is wrong. The physical reaction is that the entire body regrows itself, remaking itself per the Extremis instructions. Extremis itself, the original information package, is not involved; neither are "nanobots."

After the entire Stark 'dataspine', the central data processing center which governed all, or at least the pertinent portion of Stark technology, was infected with a hyper-advanced, Skrull-developed computer virus during the "Secret Invasion" storyline, Tony lost the ability to use Extremis' interface functions and consequently the armor was rendered obsolete. For the 2008 "World's Most Wanted" storyline, Tony used older armors, such as the Heroes Return and Classic Red and Gold versions.

Argonauts
Sometime after the Extremis transformation, during an attack by the new Super-Adaptoid, Tony Stark realized he could command several armors at once. Building on this, and realizing the world was becoming an increasingly dangerous place, he decided to construct a "team" of Iron Men—hyper-advanced drones that would be under his direct mental command, just as his own armored body. Unfortunately, the "Argonauts" were abused and destroyed before they ever could serve for good. They included:


 * "Space Ghost": space-flight capable, could reach low Earth orbit under its own power; nearly impossible to detect espionage model; possibly intended as a satellite-killer.


 * "Submariner": streamlined for great speed underwater; capable of using the ocean itself as a weapon, it apparently unleashed several tsunamis, and was able to overpower Namor, the Submariner, under water - an incredible feat.


 * "Adamantium Man": equipped with practically indestructible "Stark-Chobham" armor, an experimental composite of carbon nanotube-reinforced ceramics, laced with adamantium.


 * "Digger": enormous drone, possibly over a hundred tons; equipped with (shielded) Antarctic Vibranium (which dissolves any metal) helmet dome and a specialized repulsor/unibeam system which allowed it to tunnel at incredible speed.


 * "Hulkbuster II": also a massive drone, ostensibly designed mainly for raw power and toughness, to take on the Hulk. It proved entirely capable of taking on the Avengers. Like its predecessor, Hulkbuster II bore a distinct resemblance to Juggernaut.

While extremely powerful, the drones were useless once Tony Stark rendered himself clinically dead.

Modern Hydro Suit
During the Civil War arc of Wolverine solo series, Wolverine borrows Stark's armor to pursue Namor who is undersea in New Pangea. A new hydro suit is used by Wolverine which reflects the style of the Extremis generation Iron Man suit.
 * First Appearance: Wolverine (vol. 3) #45 (August 2006)

Hypervelocity
This new iteration of the armor possesses enhanced repulsors, housed not in gloves but in high-strength manipulator waldoes (giving the armor somewhat longer arms than usual); multiple-mode bootjets that can operate both with and without oxygen intake; improved structural integrity for the armor; an improved "chameleon mode" and a "supercavitation spike", projecting upward from the back, which apparently creates a sort of "bubble" so that the armor can travel underwater at near-supersonic speeds. A massive amount of electrical energy is stored in a spinning, superconductive capacitor ring on the back.
 * First Appearance: Iron Man: Hypervelocity (January 2007)

The most radical feature of this armor must be that its vastly increased computing power allows it to make a "back-up" of Tony's own mind, so that in the event of critical injury of the wearer, the armor can act as him, with all his knowledge, insight and experience. The effect is so complete that the armor, thus activated, referred to itself as "Tony 2.0."

After several hours of existence, the armor managed to develop a program that enabled it to function at "hypervelocity" - effectively thinking and moving at a much, much faster timeframe than everyone else.

Note that this story is set before "Extremis", though it was published afterwards.

Hulkbuster Armor MK II
In the World War Hulk event, Stark designed a new Hulkbuster armor, in order to battle the Hulk upon his return from space. He does so in World War Hulk #1, and initially was able to hold his own against his foe. The new armor was built as a large exoskeletal shell which fits around his normal armor and is equipped with rocket-boosted gauntlets, capable of punching the Hulk back several miles. It is also equipped with adamantium-tipped injector needles, which Stark used in an attempt to suppress the Hulk's power with S.P.I.N. Tech nanites, but the nanites failed due to sabotage (see Avengers: The Initiative #4). With the damage done by the Hulk and the entire Stark Tower collapsing on the already damaged armor, it was unable to continue functioning. It briefly re-emerged as a host body for the demon Zom, who attempted to use it to access S.H.I.E.L.D. technology and destroy New York City by shifting it into the Negative Zone; Zom was defeated by the efforts of the self-styled "Renegades" (Amadeus Cho, Hercules, Angel, and Namora), and the armor was used by Amadeus Cho as a temporary support to shore up structural damage caused in the battle.

Mark 1616 (Rescue)
In the 2008-09 "Dark Reign" storyline, Norman Osborn blamed Stark and Maria Hill for the Skrull invasion in the "Secret Invasion" storyline. Stark and Hill became fugitives, but before Stark fled, he left a suit of armor for his right-hand woman and best friend, Pepper Potts. The suit, which is designated Mark 1616, but named Rescue by Potts, represents a hybrid of repulsor technology and portable electromagnetic superfield generators that give the suit flight, speed, strength, and magnetic field manipulation. Its electromagentic forcefields are powerful to enable Rescue to stop a falling jet airliner without physical contact with it, and can also be used as an offensive weapon with other armored opponents. The suit's physical strength enables it to hold up a stilt mansion felled by an earthquake, and to rip the lower leg of the Black armor. The armor also features an artificial intelligence named J.A.R.V.I.S. that acts as a guide for Potts. During the 2012 storyline "The Future", Potts and Carson Wyche came to suspect that J.A.R.V.I.S. was compromised, and when they attempted to troubleshoot the Rescue helmet, J.A.R.V.I.S. took control of the Rescue armor, and took Potts and Wyche hostage. J.A.R.V.I.S. was disabled by James Rhodes with a source-focused electromagnetic pulse from the Black armor.
 * First Appearance: The Invincible Iron Man #10 (April 2009)

Mark 0
The Iron Man Mark 0 is the original armor Stark built in Afghanistan, which was improved upon his return to the United States with an onboard operating system, lenses, heating and cooling systems and rudimentary repulsor weapons. Stark used it to escape from Norman Osborn during the "World's Most Wanted" storyline, which ran concurrently with the company crossover "Dark Reign". Stark resorted to donning the Mark 0 after the brain damage he had inflicted upon himself in the course of erasing the Superhuman Registration Act database from his brain made it impossible for him to use any of his more complicated armors. The mentally incapacitated Stark and the Mark 0 armor were easily defeated by Osborn, who engaged Stark while wearing the Iron Patriot armor.
 * First Appearance: The Invincible Iron Man (Vol. 5) #18 (November 2009)

Space Armor Add-on
This device is an rocket booster-like apparatus which is capable of recycling food and waste materials of the wearer, and can sustain the wearer for a few weeks, it can be eqquiped to different armors such as the Iron Man Armor Model 29 or Model 30 to allow it to be used for unusual missions, principally, in the space.
 * First appearance: The Invincible Iron Man #1 (July 2008)

Prison escape Armor
When Stark was accused of destroying the Russian city Volstok, where Anton Vanko lived, he developed an armor similar to the Mark I from the feature film in order to escape the prison where he was being held. He ended up using it in a fight with Vanko, now as Whiplash, who wanted revenge. The armor was partially destroyed, but Stark could escape both prison and his enemy.
 * First Appearance: Iron Man vs. Whiplash #2 (February 2010)

Bleeding Edge Armor
In Invincible Iron Man #25 (2010), Tony creates a new armor in the aftermath of the "Stark: Disassembled" storyline. Created by writer Matt Fraction and artist Ryan Meinerding, this new armor is sleeker in appearance, and is featured in the 2010 crossover storyline, the "Heroic Age".
 * First Appearance: Iron Man (vol. 5) #25 (June 2010)

When asked if the Bleeding Edge is an upgrade to Extremis, Tony Stark comments, "Nah - this is what comes next." As such the new armor is a part of Tony Stark's now-posthuman biology - it is stored inside Tony's body in its entirety, "manifesting" itself when mentally commanded.

The neurokinetic user-controlled morphologic nanoparticle bundles that form the suit reside in Stark's body, and form a fibrous wetweb of iron and platinum, that can be commanded to form any type of structure upon Stark's skin, such as large boxing gloves, or weapons, including large guns extending from his arms or a lightsaber-like energy sword with which Iron Man was actually able to harm one of the Worthy during the 2011 "Fear Itself" storyline. The nano-machines can even mimic the appearance of clothes, and then dissociate to transform into the Iron Man armor whenever Stark wishes. The suit adds less than twenty-five pounds to Stark's body mass, and can stop a howitzer shell.

The armor and Stark's own transhuman body are powered by the high-yield arc reactor mounted in his chest. The high output of the arc reactor has greatly augmented Stark's intelligence and provided him superhuman-level multitasking and learning capabilities. Unlike earlier armors, this new armor does not appear to rely on motors and servos for motion. Instead, the nano-machines create a secondary artificial musculature over Stark's body, upon which additional rigid structures are assembled. This also enables the armor to self-repair and be almost invulnerable, as the armor is capable of transforming and healing itself as long as the power output from the arc reactor is not interrupted or terminated; when the armor was briefly apparently destroyed in a fight with an alternate version of the Scarlet Witch who was one of Apocalypse's Horsemen, it was restored to normal after only a matter of seconds (although it was still out of action long enough for Stark to need rescuing by Spider-Man to stop himself hitting the ground as he fell). Doctor Octopus is also able to disable the armor using technology derived from the armor of Iron Man 2020.

The suit's repulsors, which are located around the knuckles, chest, back and legs of the armor, as well as in the traditional palms, now function also as cameras, or "eyeballs", which afford Stark a 360-degree panoramic view around himself. Temporarily replacing the suit's primary composite - Iron/platinum - with carbon nanotubes rendered it unaffectable by Magneto's powers when he and Iron Man engaged in combat over Utopia.

After Tony decides to retire as Iron Man, he undergoes a surgical procedure that expels the Bleeding Edge technology out of his body, rendering the armor inert.

Iron Destroyer
During the Serpent's War, which occurred in the 2011 "Fear Iself" storyline, Iron Man journeyed to the realm of Asgard, the home of his fellow Avenger Thor, in order to procure weapons to fight Odin's brother, The Serpent, and his generals, the Worthy, who were ravaging the Earth. In addition to the hand-held weapons he had forged for his fellow Avengers, Iron Man's armor received an additional coating of Uru by Asgardian blacksmiths, as well as magical enchantments by Odin. Iron Man referred to this manifestation of his armor as the "Iron Destroyer", for its resemblance to the Asgardian weapon, the Destroyer. Its magical enhancements disappeared when Odin left Earth at the conclusion of the Serpent's War, and Iron Man vented the uru from the suit's molecular structure before returning the metal to Asgard, where it was melted back down with the other loaned weapons.
 * First appearance: Fear Itself #7 (December 2011)

Phoenix-Buster
When the dreaded cosmic entity known as the Phoenix Force is revealed to be returning to Earth, the Avengers and the X-Men fight over the fate of Hope Summers, who is expected to become its host. The Avengers believe it will destroy Earth, while the X-Men believe that it would restore the balance of life on the planet by restoring the mutant species. Stark and Henry Pym developed a massive armor to disable or destroy the Phoenix Force, but it results in the Phoenix Force splitting into five parts, each seeking out one of the X-Men.
 * First appearance: Avengers versus X-Men #5 (August 2012)

Black armor
In the 2012 storylines "Demon" and "Long Way Down", Stark is targeted by Justine Hammer, Ezekiel Stane and the Mandarin, who publicly expose the fact that Stark was using his armor while under the influence of alcohol during the "Fear Itself" storyline, and manipulate the government into forcing Stark to wear a monitoring device on his arc reactor that gives them the ability to shut down his access to the Iron Man armor. To get the device removed, Stark capitulates to venting the Extremis material from his body, quitting Iron Man entirely, and secretly arranges to fake James Rhodes' death, in order for Rhodes to become the new Iron Man. Rhodes' new armor is a black suit whose only visible features are glowing panels and metallic gray gauntlets and boots. This suit possesses a cloaking device that turns it invisible, and can handle underwater pressures exceeding the tolerance limits of the villain Firepower. It can also project freezing cold in a manner similar to the X-Man Iceman, and can release a multitude of ball bearing-sized explosives from compartments mounted on its shoulders that can be directed at an enemy. Pepper Potts' Rescue armor is strong enough to rip the armor off the armor covering the lower leg of the Black armor's occupant, though the Black armor can emit a source-focused electromagnetic pulse that can disable the Rescue armor. The Black armor is later confiscated by Stark, leaving Rhodes without a suit.
 * First appearance: The Invincible Iron Man #517 (July 2012)

Anti-Mandarin rebellion armor
In the final issue of the "Long Way Down" storyline, Mandarin reveals that he has control of Stark's mind, and in the continuing storyline, "The Future", has enslaved Stark, forcing him to build the apocalyptic weapons known as Titanomech in Mandarian City outside of Mongolia, alongside other enslaved enemies of Iron Man, in particular Ezekiel Stane. Stark and Stane cooperate in order to escape Mandarin, during which Stark builds another suit. This suit is red and gold like Stark's previous suits, but incorporates a number of metallic grey outer surfaces, particularly on the upper body of the suit.
 * First appearance: The Invincible Iron Man #523 (October 2012)

Black and Gold Armor
This armor debuted in the first part of the 2012 "Believe" storyline, which launched the fifth volume of the Iron Man series as part of the Marvel NOW! promotion. After his return from a spacial journey, Stark started creating new technologies, one of them being this black and gold armor, which Stark indicates is a testbed for new suits, and is composed by "smart-metals [that] align to a subdermal ghost of a skeleton" as described by himself. This suit can be stored in a fluid "putty" form in a briefcase, and which Stark can mentally command to cover his body. This version of the armor has a circular chestplate over the arc reactor, and like the Bleeding Edge armor, secondary repulsors are featured all over the armor, though larger in diameter. They are located on either side of the main arc reactor, on the shoulders, on each hip, on each wrist, and on top of each hand. Weapons include a wrist-mounted gun that can fire armor-piercing tasers.
 * First appearance: Iron Man (vol 5) #1 (January 2013)

Stealth Armor MK IV
This armor debuted in the third installment of the "Believe" storyline, and was utilized by Stark during a raid on the home of a South American drug lord. The armor utilizes light-bending and holographic technologies to appear invisible, as well as alter its own appearance in order to impersonate others. It lacks shields or any offensive repulsors, making it risky to use in anything other than espionage operations. Despite lacking conventional weaponry, the suit does possess the ability to administer a powerful sleeping gas.
 * First appearance: Iron Man (vol. 5) #3 (February 2013)

Heavy Duty Armor
Described as starting "Where War Machine leaves off", the Heavy Duty armor is a large, bulky suit that focuses on firepower. In addition to standard repulsor weaponry, the armor possesses a large rotary cannon that is built into the left arm, and a gun turret positioned over the right shoulder. The suit also sports a personal force field, as well as plating that according to Stark, is thick enough to withstand blows from a Hulk.
 * First appearance: Iron Man (vol. 5) #4 (February 2013)

Godkiller Armor
Making its first appearance at the end of the "Believe" arc, the Godkiller armor was designed by Tony with an emphasis on space travel. The suit sports back-mounted rocket thrusters and a redesigned helmet, which looks radically different from the faceplates featured on the previous armors. The new armor also contains an A.I named P.E.P.P.E.R., which is modeled after Pepper Potts.
 * First appearance: Iron Man (vol. 5) #5 (March 2013)

Armors from alternate realities and possible futures

 * Iron Man 2020 - Arno Stark bought the corporate identity of Stark Industries, and apparently this included Iron Man. Unlike his heroic ancestor (actually, Tony might be his uncle, once removed) he found himself working as a ruthless mercenary to bolster the financial reserves of his company. His armor was recognized to be both more powerful and more combat-oriented than that of the twentieth-century Iron Man. Decades later, this same armor (although possibly upgraded by Doctor Doom) is worn by Andros Stark, the villainous Iron Man of 2093.
 * Heroes Reborn "Prometheum" Armor (See also "Heroes Reborn-armor"); originally an experimental self-contained, armored life-support and combat system. It was a joint project of Tony Stark and Connor "Rebel" O´Reilly, but it proved dangerously unstable, and Rebel was killed in the testing stage. The project was abandoned and Tony Stark went into a spiral towards psychological self-destruction. Ironically, years later, when he went to investigate an incident at one of his more remote business annexes, his helicopter was attacked by the newborn Hulk of that reality and crashed where he was impaled by debris. He was forced to don an upgraded version of the experimental armor which had been stored at the annex to save his own life, and from that day on fought on as Iron Man. Later, he comes face to face with a resurrected Rebel, outfitted with another version of his armor which had been completely reimagined by Doctor Doom.
 * Iron Man of Earth X/Iron Manor - In the world of Earth-X, the whole world has become exposed to an airborne agent which causes everyone to mutate into superpowered beings. Tony Stark sealed off his factory complex while still inside, fearful of being changed into a `super´-version of himself. Over the years, he constructed an army of Iron Men, intended to be used as a worldwide police force, but never used- again for fear of being corrupted by such power. Instead, he built robotic versions of the deceased Avengers, otherwise remaining mostly passive inside his fortress. Forced into action by the arrival of the Celestials, he reveals that his entire factory was a final, titanic armor; he manages to delay the Host of the immense aliens, but was finally destroyed.
 * Marvel Mangaverse Iron Man - In this universe, Tony Stark vanishes after fighting Namor one last time... and his position as both industrialist and Iron Person is taken by his twin sister Antoinette (Toni) Stark, a former agent of S.H.I.E.L.D. She expands the paradigm into an entire army of every conceivable form of Iron Man, from flying weapons platforms (one of which is a clear homage to the RX-78GP03 Gundam "Dendrobium Orchis" from the Gundam anime franchise), to 100 ft mechas, to platoons of armored soldiers... all of which proves entirely useless against the Incredible Hulk. Meanwhile, it is revealed Tony Stark is still alive - albeit reduced to a head in a life-support unit because of spinal cancer. He initially equips the Avengers (Captain America, Vision, Hawkeye and the Scarlet Witch) with four super-powerful vehicles, capable of combining into yet another skyscraper-sized Iron Man mecha (bringing new meaning to their classic battle cry, "Avengers Assemble"). This, too is destroyed by the Hulk. Later, when targeted by a conspiracy against all superheroes in the world, the disembodied Tony Stark dons a cybernetic body to once again become Iron Man.
 * Ultimate Iron Man.jpgUltimate Iron Man - The Tony Stark of the Ultimate Marvel universe wears an armor that is bulkier and more difficult to operate. When the USA was invaded by foreign armies of superhumans, Tony Stark deployed "Iron Man 6," a gunship that might very well be the largest "armor" in any known reality (the flying fortress could be over 1000 ft across). The main armor requires a full behind-the-scenes support team to maintain and operate at full proficiency. In subsequent storylines like Ultimate Comics: Armor Wars, and Ultimates 3, he has built dozens of armors since the Ultimatum wave.
 * Iron Maniac - An alternate Tony Stark from a world in which the Avengers were drawn into outer space, lured into interstellar battle and effectively destroyed by a warlike alien race. His spirit shattered, he returned to Earth, apparently to find that Reed Richards had planned to take over the world (to date, the exact circumstances behind his descent are unclear). He decided to take control of the planet himself "to save it" and adopted methods more like those of Dr. Doom, killing, among others, the Human Torch, and adopting a bulkier gray armor that resembled his original suit, although possessing far more advanced weaponry than he had back then, including a weapon capable of temporarily negating the FF's powers and a means of escaping from mystical bonds. He was accidentally drawn into the 616-universe, and after an extended battle with the local heroes- initially facing the Fantastic Four and Doctor Strange before his attempt to escape saw him fighting Captain America, the Black Widow, Spider-Man and X-23 - was incarcerated. He escaped, adapting a hyper-advanced LMD into a new set of armor that could shape itself according to his thoughts and form any weapon he could conceive of, and called himself the "Iron Maniac"; since everything in this world was backwards from his perspective, this was his way of stating he was sane and everyone else was mad. He is a cyborg; at the least his chest is armored.
 * The Lord Iron armor from Marvel 1602. A Spanish scientist who was taken captive by the English in the war and forced, through torture by David Banner, to devise weapons for them. He now needs his massive armor to survive; it harnesses electric power from simple chemical cells, but can also absorb lightning bolts. It provides increased strength, electrical attacks and some sensory enhancement.
 * Somatic Combat Vehicle from Iron Man: Crash; In the words of Tony himself: "My SCV secondary body protective shielding is formed of a titanium beryllium geodesic alloy doped with nickel iron mylar superstrate and interlaced microcrystalline quartz fiber and synthetic rubber endoform & ectoform substrate layer." This armor's various properties (strength, lightness, structural integrity etc.) are all a result of optimizing the interaction between the properties of various materials, all balanced out on a molecular level. In a sense, this armor is one huge "tile" like the millions of tiny ones the contemporary armor is made out of.
 * Overload armor from What If (vol. 1) #64 ("What If Iron Man Sold Out?") - In an alternate world where Tony Stark went public with his armor instead of keeping it for himself, the "arms race" quickly completely escalated, with more and more advanced armor being developed by all parties from the U.S. government and S.H.I.E.L.D. to HYDRA and the Mandarin. Ultimately, the worst threat turned out to be Magneto, who was infuriated by the lack of interest in the plight of the Mutants, who were being hunted by Starktech Sentinels. He used his power over metal to defeat everything that was thrown at him, but was ultimately defeated by Iron Man in a towering suit, which composed completely out of polymers.
 * Sorcerer armor from What If (vol. 1) #113 ("What If Tony Stark was Sorcerer Supreme?") - In a reality in which events led Tony Stark to become the main student of the Ancient One (instead of Stephen Strange), he ended up combining his understanding of technology as well as magic to create an armor which incorporated both. It held a vast storage of magical spells in its memory, ready to be deployed at a moment's notice. This armor was lost when Tony Stark sent it on an endless dimensional quest, carrying the body of the dread Dormammu, forcing the dark lord (in his astral form) to pursue it.
 * Ironheart armor from Avataars: Covenant of the Shield
 * In What If?: Civil War, released in December 2007, Tony Stark died from the Extremis injection and Captain America went on to lead all the heroes in the civil war which broke out when the government tried to enforce the Superhuman Registration Act. To provide the inspiration which Tony had given in life, Steve briefly wore an Iron Man armor with a red, white and blue color scheme.
 * In the Marvel limited series Bullet Points, an alternate reality where Dr. Abraham Erskine is killed (along with a young MP Benjamin Parker) one day before injecting Steve Rogers with the Super Soldier formula, thus terminating the Project: Rebirth, and initiating Project: Iron Man, in which Rogers takes place instead, making him Iron Man until he is killed in a fight with this reality's Hulk, Peter Parker. Years later, when Galactus attacks, Tony Stark finally armors up with the suit.
 * In What If?: Age of Apocalypse, Captain Britain wears an early model of the Iron Man armor, custom painted as his uniform, as part of the Defenders.
 * In Marvel Zombies, Forge is shown using an enhanced version of the original armor against the zombies.
 * In the 2008 Black Panther annual story "Black to the Future" (a What If?-type story set in 2057) the USA challenges the nation of Wakanda's global dominance with an army of Iron Men. This force is led by an Iron Man giant robot piloted by Tony Stark himself. This huge machine (easily as big as the New Avengers/Transformers giant suit) could only be controlled by direct neural interface, so Tony Stark was physiologically injured when the suit was damaged by Wakanda's panther-shaped giant robot. Tony's death ended the war and inspired a Wakandan-led global peace.
 * In the "House of M" storyline, Tony Stark is still the head of Stark Industries but also the star of the hit TV show Sapien Death Match along with his father, and Johnny Storm. His battle armor for the show is similar to his original gold armor, however, it is then revealed that he was working on a much more advanced armor, more advanced than his current armor in the normal reality. This armor was chunkier, had large wing-like jets coming from the back and a cannon on its right hand. It also has counter magnets built in, to prevent Magneto from controlling it.
 * In the 2007 New Avengers/Transformers miniseries, Stark used a giant armor, the size of a Transformer; it allowed Iron Man to go head-to-head with the invading Decepticons. Due to the massive energy requirements, this armor would quickly run out of power, until recharged by Optimus Prime, Jazz and Bumblebee.
 * In Incredible Hercules #125, the evil Amazon Artume had used a mystical object to change the world into her vision of it. In this world, men were an oppressed and debased part of society, and a male resistance movement existed. Practically the last member of it was Hercules, who wore cybernetic armor made for him by Tony Stark, who had long since been executed.
 * Galactus Buster armor, so far known only to be featured in his ending scenario for the video game Marvel vs. Capcom 3: Fate of Two Worlds.

1994 animated series
As noted above, Iron Man's modular armor was his standard suit for his appearance in the 1990s Iron Man animated series, but with a slightly modified face plate to give it the traditional mouth-slit. The suit was redesigned in the second season of the show, most significantly by restoring the "mouthless" appearance of the armor. (The season 1 armor appeared in a flashback early on)

The trademark of a changing armor remained a constant in the animated series, with the first season featuring the hydro-armor and deep space armor, straight from the comics. The second season, however, was when the variant armors became a focal point of the series; the new modifications Stark made to his suit allowed it to shape-shift into different forms with specialized capabilities that could be called upon for the assorted situations he found himself in. The hydro-armor and space armors were incorporated into this mechanism, and more armors from the comics such as the stealth armor and Hulkbuster armor were introduced. The series also introduced an array of original situational armor designs, including:


 * Subterranean drill armor - Brown and gold, with an arm-mounted pneumatic drill for underground burrowing.
 * Inferno armor - Red and gold with pink highlights, this armor was resistant to extreme temperatures and outfitting with fire-extinguishing foam, which proved helpful in combat with Firebrand.
 * Samurai armor - Never actually used in combat, this highly stylized armor was blue and grey.
 * Radiation armor - Blue and silver armor to shield against radioactive danger, capable of firing x-ray blasts.
 * Lava armor - Red and silver armor that can resist submergence in magma, which proved helpful when Iron Man had to recover one of the Mandarin's rings from within a volcano.
 * Magnetic armor - Purple and silver, with the ability to generate electromagnetic pulses, once used by a microscopically reduced Iron Man to fibrilate Hawkeye's heart.
 * Bio-energy armor - DNA-powered red and gold armor, used against the Mandarin's anti-technology field in the two-part series finale "Hands of the Mandarin".
 * Hydro armor - Yellow with a glass-domed helmet, is used for underwater situations.
 * Space armor - Used to break through the Earth's atmosphere, the only thing that appears to be different is that it has a jet pack.
 * Stealth armor - Dark gray, is used to stay silent and is unable to be traced by radar.

The toyline also featured two armors which did not appear in the series; an entirely silver Arctic armor and the Silver Centurion suit, dubbed Hologram armor.

Fantastic Four: World's Greatest Heroes
Several types of Iron Man armors were also featured in the Fantastic Four: World's Greatest Heroes episode "Shell Games". The armors that were featured were the Mark I Armor, Stealth Armor, Hulkbuster Armor, Arctic Armor, War Machine Armor, and the Silver Centurion Armor.

The Invincible Iron Man
In the 2007 direct-to-DVD film The Invincible Iron Man, Tony with Rhodey's help creates a grey and bulky suit of armor (similar to the original Iron Man armor that Tony and Yinsen created in the comics) in order to escape from caves. After returning to Stark Industries in America, Tony reveals to Rhodey that he had previously used his company's resources to create several multi-use armors (including the Hulkbuster armor, the War Machine armor, and Ultimate Iron Man's armor) that he had been keeping in storage until the time was right to reveal them to the public. Tony first uses his Underwater suit to fight off the Elementals, destroying one while sustaining minor damage to the suit. Tony subsequently uses a red-and-yellow suit (resembling Iron Man's standard armor) to destroy two Elementals in a volcano, although there was severe damage to his suit. When he returns to China, Tony returns to using his grey suit to fight the last Elemental, an army of Terracotta soldiers, a giant dragon, and even the Mandarin.

Live-action films
Several types of Iron Man armor appear in the 2008 film Iron Man, the 2010 sequel Iron Man 2 and the 2012 film The Avengers. A distinguishing feature of the armors featured in these films is the need for outside assistance to assemble them onto and/or remove them from the wearer, either from another individual or mechanical devices designed for the task. In Iron Man, Tony Stark dons the Mark I armor with aid from fellow captive Yinsen, while the Mark II and III are shown assembled and removed by a bulky mechanical system within Stark's home workshop, which requires him to remain stationary during the process. A similar system built into the main stage of the Stark Expo is shown removing the Mark IV armor from Stark in the opening scenes of Iron Man 2. The Mark VI armor's assembly and removal occurs off-screen in Iron Man 2, but it is shown being disassembled twice in The Avengers by a more streamlined process integrated into the penthouse balcony of Stark Tower, which removes the armor in motion as Stark walks into the interior of the suite. The Mark V "travel armor" of Iron Man 2 and the Mark VII of The Avengers both demonstrate internalized mechanics that allow them to unfold and form around Stark's body into full armored suits, and the helmet of the Mark VI armor can be removed and re-attached by the wearer if desired, as seen in Iron Man 2 and The Avengers.

Mark I: As in the comics, the first armor which Stark builds with Yinsen's help while in captivity in Afghanistan during the first film is crude and bulky. It had the ability to amplify Stark's strength tremendously and protected him from small arms fire. The suit was armed with flamethrowers and a missile launcher, as well as a limited rocket jump capacity to allow Stark to exit the immediate hostile area after he sustained damage to the suit's knee joints during his escape. The suit was also able to protect the occupant from the effects of extreme g-forces. However, the rockets failed shortly after the start and the suit shattered upon landing, which forced Stark to abandon it to attempt to reach friendly territory. Later, Stark's enemies found the abandoned armor, using it as the base design for Obadiah Stane's Iron Monger suit (although Stane still needed to steal the power supply from Stark). The second film shows that Stark displays the Mark I within his workshop, with the label "Reconstruction", and has it apparently retrofitted with an independent arc power source, allowing it to be operated by other users that have access to Stark's lab. The first prototype was based on the original gray suit from Iron Man's first appearance.

Mark II: Upon returning home during the first film, Stark developed the sleeker, polished stainless steel Mark II prototype version with improved flight capability. Furthermore, the Mark II was the first one to have a holographic HUD, repulsor technology and to operate with remote assistance from JARVIS (Stark's artificial intelligence), who manages the armor's systems at Stark's command and also have variable control surfaces for active flight control by JARVIS to automatically stabilize the suit in flight. Like the Mark I, the Mark II was able to protect the occupant from the effects of extreme g-forces. However, it was prone to icing at high altitudes, which would cause it to stall. The Mark II was then replaced with the Mark III's gold-titanium alloy to correct the problem. However, Rhodes briefly contemplated using it. The second film shows that Stark displays the Mark II prototype within his workshop, with the label "Prototype", and has it retrofitted with an independent arc power source as shown when it was operated by James Rhodes in hand-to-hand combat against Stark in the Mark IV armor; this suit is later retrofitted with conventional weaponry, thus becoming the War Machine armor.

War Machine: After Rhodes confiscates the Mark II armor on behalf of the United States government in the second film, it is heavily weaponized by the United States Air Force for their "War Machine" project. The Mark II's ballistic weaponry upgrades were provided by defense contractor Justin Hammer. Two weapon pods containing a 9mm submachine gun and a 5.56 mm assault rifle, respectively, are mounted on both forearms. An external 7.62mm minigun is attached via a gyro-stabilized arm mounted behind the right shoulder. Enclosed inside of the left shoulder is a 40 mm grenade launcher capable of firing heavy munitions, including a bunker-buster warhead (which Hammer personally nicknamed the "Ex-Wife") which performed well below expectations when it was used against Vanko's suit, failing to attain any penetration or indeed have any appreciable effect. The energy repulsors from the original design are still located in the palms and chest. Though Rhodes is the War Machine suit's primary pilot, its internal computer systems were modified and linked to the Hammer Industries mainframe, allowing it to override its' occupant's inputs and be operated by remote. The Iron Man 3 prequel reveals that the War Machine armor was later confiscated by Stark, who then supplied Rhodes with a sleeker, more advanced model.

Mark III: The armed red/gold Mark III prototype armor was the last armor built in the first film and was built with a fictional gold-titanium alloy (a durable composite used in the Seraphim series of Stark Industries' satellites) to resolve the freezing problem. Like the Mark II, the Mark III has a holographic HUD and to operate with remote assistance from JARVIS to manage the armor's systems at Stark's command and also have variable control surfaces for active flight control by JARVIS to automatically stabilize the suit in flight. Like the Mark I and II, the Mark III was able to protect the occupant from the effects of extreme g-forces. It was able to withstand small arms fire, a close proximity explosion from a tank shell (including a resulting fall from several thousand feet up), followed by a close proximity explosion from an air-to-air missile, several hits by 20mm Vulcan shells and a high speed collision with an F-22 Raptor, with only minimal cosmetic damage. In addition to repulsors, it was armed with anti-tank missiles on the wrists, anti-personnel guns on the shoulders that could pick out individual targets, and flare launchers on the hips. When Stark reverted to the original reactor after the second reactor was stolen by Stane to power the Iron Monger suit, the first reactor had great difficulty providing enough power to the Mark III suit, being depleted to around a fifth of its power supply simply by flying Stark from his home to Stark Industries, with the last 20% being exhausted and was extremely damaged in the fight against Stane in the Iron Monger armor. The suit also requires a form-fitting jumpsuit to be worn, as any loose clothing would get caught in the suit's joints. The second film shows that Stark displays the Mark III prototype within his workshop, with the label "Battle Damaged". The Mark III armor's look was inspired by the signature red-and-gold armors in the comics.

Mark IV: The Mark IV armor is the first shown armor in the second film when Tony Stark uses it to kick off the Stark Expo. The suit has a differently-colored HUD, although its full arsenal and fighting potential is not explored in the movie. When it was shown on display within Stark's workshop, the Mark IV was labeled "Awaiting Upgrades" above it. The helmet is also shown to be removable as a single piece, evidenced by it sitting next to Tony while he eats donuts in the Randy's Donuts sign. It also does not require a jumpsuit to be worn unlike the Mark III, allowing regular clothing to be worn underneath. A drunken Tony dons the Mark IV during his birthday party and then engages in combat with James Rhodes, who commandeers the Mark II armor to prevent Stark from endangering his guests. The battle ends when the combatants both fire repulsor beams at each other, creating a huge explosion.

Mark V: Also introduced in the second film is the Mark V travel armor, a portable suit developed for emergency use that is lightweight and flexible enough to take the form of a briefcase that's handcuffed to Happy Hogan. The armor is deployed as Stark is forced into a confrontation with Ivan Vanko in Monaco. By kicking open the case, inserting his hands into the protruding gloves and placing the main assembly onto his chest, the armor folds out around Stark, quickly forming into a full red-and-silver armor. This armor is shown to be durable enough to withstand the focused repulsor energy of Vanko's energy whip attacks, though it sustained heavy internal and external damage. While this model features the palm-mounted repulsors, any potential flight capability is not shown (while in the game based on the second movie it is established that the suit can fly, but it takes all of its power just to keep Tony airborne, preventing him from carrying anything else). Because of how form-fitting the suitcase suit was required to be, the production team researched some of the classic comics armors, since they were seen as essentially variations on muscle suits. One specific aspect of an earlier armor was the color scheme from the Silver Centurion armor.

Mark VI: The Mark VI armor differs little from the Mark III and Mark IV platform; the main difference being a triangular-shaped chestplate protecting the arc reactor assembly. The major changes are to the shoulders and legs, and convey a more linear appearance that, according to concept artist and visual development supervisor Ryan Meinerding, make "Iron Man look like he's built for flying." The suit was also designed for the greater amount of fist fighting on the ground seen in the second Iron Man movie. The new model was shown using two weapons not show in previous models: a multi-fire adhesive grenade launcher in the upper arm, and one-time-use hand-mounted laser weapons, powerful enough to cut through several Hammer Drones cleanly in half. The suit sustained heavy damage in the final battle of the second film, but was fully repaired by the beginning of The Avengers. The Mark VI has the ability to operate underwater, as Stark uses it underwater to activate the arc reactor connected to Stark Tower. It is also able to withstand combat with the Asgardian Thor and was capable of absorbing lightning from Thor's hammer Mjolnir (increasing the suit's power level to over 400% capacity) and redirecting the energy back at him, though Thor was able to damage the suit's wrists with his bare hands. The armor retains the red and gold color scheme, but was designed by Adi Granov and Phil Saunders to be sleeker than the Mark III.

Mark VII: After the Mark VI sustains damage during the attack on the S.H.I.E.L.D. Helicarrier, Tony Stark uses the Mark VII armor to help the Avengers repel the Chitauri invasion of Manhattan. The Mark VII is assembled onto Stark's body via Colantotte wristbands that emit a signal to summon the armor, which is launched as a bulky capsule, and then assembles itself onto Tony using advanced laser technology, in a manner similar to the Mark V, after scanning his body. The armor goes back to the circular chestplate used before the Mark VI and features silver elements on the thighs and shoulders in addition to the familiar red and gold color scheme. The Mark VII was not designed for deep space travel, as the armor's systems fail when Stark is teleported through the Tesseract generated portal into space, causing him to lose consciousness as he plummets back to Earth. Phil Saunders stated that (Avengers director) Joss Whedon was looking for something that had the 'cool' factor of the suitcase suit (from Iron Man 2), while still being a fully armored, heavy duty suit that could take on an army in the final battle." To that end, Saunders borrowed ideas that had been proposed in Iron Man 2 as well as some ideas that had been abandoned in Iron Man and merged them together in a modular suit that has big ammo packets on the arms and a backpack.

Arc reactor: In the first movie, the armor suits are powered by a miniaturized arc reactor, a fictional clean energy source. The arc reactor is also used to power the electromagnet that protects Stark's heart from the shrapnel embedded in his chest. The first reactor was allegedly capable of powering the electromagnet protecting Tony's heart for fifty lifetimes, but after returning home, Stark developed a more efficient reactor that he used to power the Mark II and Mark III suits, although Stark reverted to the original reactor after the new model was stolen by Obadiah Stane to power his Iron Monger suit. The original reactor had great difficulty providing enough power to the Mark III suit, being depleted to around a fifth of its power supply simply by flying Stark from his home to Stark Industries, with the last 20% (as well as the emergency backup power) being exhausted during his fight with Stane in the Iron Monger armor, barely keeping Stark alive after the fight. By the second film, all of Stark's Iron Man suits are fitted with their own arc reactors, allowing James Rhodes to confiscate one. Stark also has a large scale version of the reactor that powers his factory.

The second movie reveals that the original arc reactor was first developed some years earlier in a joint effort between Howard Stark (Stark's father) and Russian physicist Anton Vanko (the father of Ivan Vanko). The film also reveals that the miniaturized arc reactor that Stark has been using for a power source is slowly poisoning him with palladium. When Stark successfully develops a new element (unidentified in the movie, but said to be vibranium in the novelization) to use as a substitute power source, he has a new suit (Mark VI) developed, which is capable of channeling the reactor's power.

In The Avengers, Stark develops a large scale arc reactor to power his Stark Tower in New York City, which is said to have the ability keep the building running for over a year with clean energy. Stark's personal arc reactor is able to absorb lightning from Thor's hammer Mjolnir, powering the Mark VI to over 400% capacity. The arc reactor also prevents Loki from taking control of his mind, as the reactor blocks this effect of Loki's staff, which normally allows Loki to do this.

Iron Man: Armored Adventures
In Iron Man: Armored Adventures, a teenage Tony Stark initially creates the first armor completely on his own. It is similar to the movie version of the Mark III armor, with a less complex design and more red. Once Obadiah Stane's scientists said the armor is "more advanced than anything we're currently working on" and that "it's years, if not decades ahead of current technology" (Tony even mentioned in the same episode that he may have "outgeniused himself" when he made the armor). In addition to the traditional abilities the armor gives (superhuman strength and durability, flight, repulsors, and the uni-beam), it is able to generate an force field around it, uses magnetic manipulation, and has other various functions, including a remote command system to enable Rhodey to control it from a separate computer terminal if Tony can't ("Secrets and lies"), a security system to prevent people from opening it when Stark is unconscious ("Seeing Red") and a secondary wheeled transportation system that enables him to "skate" when the flight system is damaged ("Masquerade"). It can even adapt to fit any size ("Don't Worry, Be Happy"). In "Ancient History 101", Stark even creates a pack that allows him to don the armor when and where he needs to, combined with anti-gravity devices so as to reduce the suit's weight (possibly based on how the comic version always carried his armor in his briefcase). The armor briefly gained intelligence in Episode 14 of Season 1 "Man and Iron Man". Problems arose due to its desire to protect Tony above all (including almost killing Whiplash, as it did in the comics) - by constantly keeping him inside itself. However, like in the comics, the armor sacrificed itself in order to save Stark during a cardiac arrest.

The first variation of the armor appears in "Cold War", when he created enhanced Thermal Gauntlets for his armor and used them to help him fight Blizzard. After the fight, he talks about creating Arctic and Space Armor.

New armors then appear in various episodes:
 * Silver Centurion: Red and silver, very similar to the original red and gold armor and its own comic counterpart in both appearance and abilities. Stark created it in the episode "Whip Lash", and used it in the same episode to fight the eponymous villain. The Silver Centurion armor made a cameo in "Don't Worry, Be Happy" and other episodes.
 * Stealth Armor: Again, initially similar to the red and gold armor, but with a different chest plate and shining cameras on the sides. First seen and used in "Field Trip". It allows Stark to become invisible and undetectable to cameras and sensors, including those used by Stark International. Unfortunately, this function burns up the power cells after a short period of time. The armor returned in "Panther's Prey" with a new design that is almost completely a bluish-black with red lights on the sides (more like its comic design). This version made several cameos in later episodes and was shown exploding in "Tales of Suspense (Part One)", though a rebuilt one was used in season 2. At the end of "Iron vs Titanium", Tony upgraded the armor with better weapons and stealth gear.
 * Hulkbuster Armor: A heavy-duty armor designed for maximum strength and endurance at the cost of reduced mobility. It has the ability to redirect energy shot at it and has powerful versions of the repulsors and uni-beam as well as missiles and shoulder mounted Gatling laser blasters. First used to take on the Crimson Dynamo in "Seeing Red" when Obadiah Stane redesigned and weaponized it and sent it after Iron Man. Tony later used it in "Uncontrollable" to fight the Hulk (a reference to its comic roots). The armor was later shown exploding in "Tales of Suspense (Part One)". Its designs were later used to create Firepower in "Armor Wars" (Tony refers to the suit by name in this episode). It has a slight resemblance to the X-Men villain Juggernaut. Stark later used the rebuilt armor to fight the Iron Monger in "Heavy Mettle".. It appears again in the episode "Rage of the Hulk", in which Tony wears it over his regular armor, before it is severely damaged by the Hulk.
 * Space Armor: A mouth-less, black and gold armor that has all of the same weapons systems as Tony’s standard armor. However, this armor also has extended life-support capabilities and an expanded propulsion system on the back (twin thrusters) for long-term flight and for flying into and maneuvering through space. Tony mentions making space armor at the end of "Cold War" and used it for the first time in "Fun with Lasers" against the Living Laser. It was later worn by Howard Stark, Tony's father, in the season 2 finale.
 * Arctic Armor: A white and gold armor contains additional systems that project thermal energy from Iron Man’s gauntlets and uni-beam. Also, Tony said the Mark II armor's sonic disrupters were adapted from this suit. It has greater life-support functions and generally resists freezing temperatures. This special suit is equipped for long-range flight. Tony mentioned making arctic armor at the end of "Cold War" and used it in "Best Served Cold" against Blizzard.
 * War Machine Armor: Whereas Tony Stark created the Iron Man armor as a multi-environment suit for exploration and rescue, the War Machine armor was created for fighting. The War Machine is as fast as the Iron Man armor, but it has numerous weapons, more powerful and bulkier than the normal armor. Equipped with more powerful versions of the Repulsors and Uni-Beam, the War Machine also sports three shoulder mounted missile launchers as well as wrist mounted machine guns and a shoulder mounted Gatling laser rifle. While Iron Man is red, War Machine is grey. The War Machine first appeared in the two-part season finale "Tales of Suspense", where Rhodes uses it to bring the Mark I Armor to Stark and help him against the Mandarin and Fin Fang Foom. Rhodey has since frequently used the suit throughout season 2.
 * Iron Man Mark II Armor: In the second season of series, Tony creates a more powerful suit of Iron Man Armor. Its design possibly originated from the Extremis Armor from the comics and the first season's Silver Centurion Armor. In addition to the enhanced versions of all the systems from the Mark I Armor, it also has wrist mounted flame blasters, shoulder mounted missile launchers, sonic disrupters (Tony mentions they were adapted from the Arctic Armor) and more powerful repulsors and Uni-Beam.
 * Rescue Armor: Also known as the Stark Solutions X-51 Stealth Infiltrator Armor, was created by Tony Stark for Pepper Potts. Essentially an upgraded version of the Stealth armor but with better Repulsors, the Uni-beam, Energy Grenades and Laser Spark blasters. Just like the Stealth Armor, it has a stealth mode equipped inside it. The suit was given to Pepper at the start of the episode "Dragonseed" as an early birthday present. The armor is recolored purple and white; rather than in the comics where the color is crimson and silver. In addition it is much less feminine looking then the comic version.

Avengers: Earth's Mightiest Heroes
In the Avengers: Earth's Mightiest Heroes series, in which Iron Man is the leader of the Avengers, his standard armors are based on the ones in the film series. In "The Kang Dynasty", he even made special suits for the Avengers for use in the space battle against Kang, excluding the Hulk (who only needed a breathing mask) and Black Panther (who was still in Wakanda).

His current armored suits give him the standard superhuman strength and durability, flight, repulsors, and the unibeam projector. They also have energy shields, an electromagnetic pulse generator, arm-mounted cannons and projectile launchers, various tools like a drill or detachable hip tasers, and can absorb and release energy.

Additional armors from the comics that were shown in the series are:
 * Mark I Armor (also based on the movie version, but with full flight capability, repulsors, and unibeam) (first seen in "Ultron-5")
 * Mark II Armor (First seen in "The Ultron Imperative")
 * Mark VI Armor (First seen in "Breakout, Part 1")
 * Mark VII Armor (His standard armor in Season 1, the design of this armor is the same as the Mark VI Armor) (first seen in "Breakout, Part 2")
 * Mark IX Armor (The new suit based on the Extremis armor, which wears in Season 2)
 * Classic Armor, (First seen in "The Ultron Imperative")
 * Silver Centurion Armor, (First seen in "The Ultron Imperative")
 * Hulkbuster Armor (A headless exterior unit over his standard suit) (first seen in "Everything is Wonderful")
 * Hulkbuster Armor II (A bulky suit that looks like the mainstream Hulkbuster armor) (first seen in "The Deadliest Man Alive")
 * Space Armor (First seen in "The Kang Dynasty")
 * Arctic Armor (First seen in "Casket of Ancient Winters")
 * Stealth armor (First seen in "The Ultron Imperative")
 * Thorbuster armor (An Asgardian Iron Man suit that was built in Asgard by Tony Stark and Eitri the Dwarf using uru metal, making its repulsors similar to Mjolnir's lightning) (first seen in "A Day Unlike Any Other")

Marvel Anime
The Iron Man anime series features an Iron Man armor similar to the movie's Mark III armor, except that in the anime the armor is only shown to be equipped with the repulsors, unibeam, and mini-rockets. Plus, instead of J.A.R.V.I.S. as the suit's AI; It has a female-voiced computer named "Computer" that sounds similar to the AI in the suit(s) of Iron Man Armored Adventures.

The plot of the series involves Tony traveling to Japan to build an ARC station and also to test a new armor: Iron Man Dio. Tony intends to mass produce Dio and then retire as Iron Man. The Dio chest power core resembles the one on the Extremis Armor, but the armor is colored blue and silver rather than red and gold. Dio's head is also slightly redesigned from the typical Iron Man armor with curved features on its faceplate. The Dio armor is stolen in the first episode of the series, and Tony is forced to fight the Dio armor repeatedly over the series. Tony asserts the Dio Armor is a knock-off of the real Iron Man armor, but Dio is demonstrated as being equal to or surpassing Tony's standard armor in terms of performance. Maybe it's because the armor's performance depends on how good the pilot is.

The SDF later create a suit of armor called "Ramon Zero", used by Captain Nagato Sakurai. It resembles a samurai's armor. The Japanese armor appears to have a red pentagon-shaped ARC reactor, is armed with powerful swords, and also uses repulsors and missiles in combat.

Yinsen, revealed to still be alive and piloting the Dio Armor, builds an army of autonomous drones called Iron Man Sigma. These drones resemble the Dio Armor, except the Sigma armor is colored army camouflage.

Ultimate Spider-Man
In the animated series Ultimate Spider-Man the episode "The Iron Octopus" reveals several prior suits developed by Stark:
 * Mark I Armor
 * Mark II Armor
 * Hulkbuster Armor
