Tok'ra

The Tok'ra are a fictional alien race on the science fiction television series Stargate SG-1. They first appear in the season 2 episode. In the show, the Tok'ra are biologically the same species as the Goa'uld who inhabit human hosts in a symbiotic relationship, and are opposed to the evil System Lords. They are one of the major offworld allies of Stargate Command.

Background
Biologically, the Tok'ra are the same species as the Goa'uld, though they are opposed to them in every way; their name "Tok'ra" literally means "against Ra," though it has gained the figurative meaning "resistance". The Tok'ra consider it an insult to be called a Goa'uld. They take only willing human hosts, providing long life and perfect health, and share the body equally. Most Tok'ra are spawned from a single Queen, Egeria, who fought the Goa'uld 2,000 years ago and was defeated by the Supreme System Lord Ra. A few other minor Goa'uld have joined the Tok'ra in the past, but the only one to do so in the past 1000 years was actually a Goa'uld spy and did not actually adopt the Tok'ra philosophy. Due to Egeria's death in, the Tok'ra are a dying race. Due to their small numbers and scarce resources, the Tok'ra favor infiltration and covert tactics meant to destabilize the System Lords and play them against one another, ensuring that no one Goa'uld becomes overwhelmingly dominant until such time as they can all be wiped out at once.

Show history
The SGC first learns of the Tok'ra in, when Jolinar of Malkshur is forced to take Samantha Carter as a host in order to survive. Carter's memories from this experience allow SG-1 to make contact with the main Tok'ra base in, and to forge an alliance against the Goa'uld. The alliance is bolstered by the blending of High Council member Selmak and Jacob Carter of Earth, and is formalized via treaty in the season 4 episode. On many occasions, the Tok'ra provide valuable assistance to Earth and vice-versa. Nevertheless, the Tok'ra are reluctant to disclose their covert operations to the SGC, and in turn the details of several Earth projects are not revealed to the Tok'ra.

In the early seasons of Stargate SG-1, the Tok'ra are mainly concerned with preventing any one Goa'uld from achieving absolute dominance over the galaxy. Thus, they assassinate Sokar by blowing up his prison moon Ne'tu in, and sabotage a meeting between Apophis and Heru'ur in. In the season 4 finale,, the Tok'ra wipe out Apophis' fleet by luring him to their base on the planet Vorash, where Samantha Carter uses a Stargate connected to another gate orbiting a Black Hole to siphon off so much hydrogen from the planet's sun that it destabilizes and becomes a Supernova. However, the Tok'ra resistance is dealt a major blow in, when the Goa'uld Anubis sends his lieutenant Zipacna to destroy their primary base on Revanna. Almost every Tok'ra on the base is killed in the attack. The only known survivor, Lantash, sacrifices himself to release symbiote poison over the area, eliminating Anubis' forces and allowing SG-1 to escape. In, the Tok'ra Delek informs General Hammond that Earth's policy of directly confronting the Goa'uld has cost the lives of more Tok'ra operatives in seven years than in the last hundred, and that their alliance may prove too costly to uphold.

The Tok'ra play a much diminished role in seasons 9 and 10 of the show, after the Ori are introduced as the main threat. They are mentioned to be searching for Supergates along with the Asgard in, and their ships join the fight against Ori motherships in. In, the Tok'ra plan to implant one of their own into Adria in place of a Ba'al clone symbiote, though in the end Adria Ascends.

They are present in Stargate Continuum to oversee the extraction ceremony of the Goa'uld symbiote Ba'al from the host.

Society and culture
Secrecy is a way of life for the Tok'ra, as that is their only defense against the armed might of the System Lords. When they arrive on a planet, they immediately move underground into special self-constructing crystal tunnels. These tunnels are collapsed when the Tok'ra depart, thus leaving no trace of their presence. The Tok'ra regularly move their bases to avoid detection by the Goa'uld. Tok'ra tunnel networks have no doors, as the Tok'ra do not keep secrets from each other.

Unlike the Goa'uld, Tok'ra symbiotes prefer to enter a new host through the mouth rather than burrowing through the back of the neck. This is because the Goa'uld wish to avoid remembering the look of horror on their host's face every time they look in a mirror. The Tok'ra have no such need as they take willing hosts, and they find the implantation scar unsettling. The human host of a Tok'ra speaks in a normal voice, while the symbiote speaks with the flanged, bass-augmented "Goa'uld voice". When switching between one and the other, Tok'ra bow their heads and close their eyes to avoid showing the Goa'uld "eye flash".

Among the Tok'ra it is customary for the more volatile of the blended Tok'ra and host to defer control of the body to the calmer of the two, which is usually but not always the symbiote. An exception to this is Martouf, who is usually calmer than his symbiote Lantash. Thus, the other Tok'ra tend to address him as Martouf rather than Lantash. When one Tok'ra is mated to another, typically both the host and symbiote are in love with his/her partner's host and symbiote.

The Tok'ra are governed by the Tok'ra High Council.

The Tok'ra dispose of their dead by placing the body on a pedestal and allowing it to be vaporized by the unstable vortex of an activating Stargate. They do not use the Goa'uld sarcophagus, believing that its psychological effects are one of the main reasons for the Goa'uld's evil.

As shown in Stargate: Continuum, the Tok'ra have apparently given up their ways of secrecy after the destruction of the System Lords and are shown to have built an above-ground, permanent city, in contrast to their previous habit of living in temporary, hidden, underground, grown-crystal tunnels.

Science and technology
The Tok'ra are master scientists despite the necessity of maintaining secrecy and the resulting lack of resources. Tok'ra forces rely on zat'nik'tels, as they lack the naqahdah necessary to build staff weapons. They have access to many technologies used by the Goa'uld, such as force-fields, memory devices and transphase eradication rods. The Tok'ra often assist the SGC in developing new technologies, and they have provided many pieces of their technology to Stargate Command when required. Tok'ra one-way force-fields are installed in the SGC's isolation rooms. Some of the most significant Tok'ra advancements are symbiote poison, tretonin, and the Kull disruptor.

Aldwin
William deVry played Aldwin, a member of the Tok'ra who has several dealings with the SGC. During SG-1's mission to rescue Jacob Carter from Ne'tu in "The Devil You Know", the Tok'ra High Council orders Aldwin to launch a weapon at the planet's core that would destroy the moon as well as Sokar's Ha'tak in orbit in a chain reaction. However, the plan would also claim the life of SG-1, Martouf and Jacob Carter, and Aldwin realizes that the only option is to help SG-1. Aldwin is later sent to the SGC to verify that after SG-1 Shifu is indeed the supposed Harcesis by using the zatarc-detecting device. Several years later, during the Tok'ra's plan to eliminate the System Lords during their high-level meeting, Aldwin guides SG-17 through the Tok'ra base on Revanna. Aldwin is killed when Zipacna attacks the planet, destroying the Tok'ra base.

Anise
Anise (meaning "noble strength") appears in a mini-arc early in season 4 as a member of the Tok'ra resistance group. Her host is named Freyja, and is played by Vanessa Angel. Anise is a gifted scientist and historian. Researching the Atanik armbands, which are rumored to give the user great strength and speed, Anise tests the devices on SG-1 and, if the test prove successful, wants the SGC to send them on a dangerous mission to destroy Apophis' new prototype mothership. Anise visits Earth again when a Jaffa named Shau'nac believes to have convinced her symbiote to join the Tok'ra, and is present when the symbiote, Tanith, is given a willing host body. When Teal'c discovers Tanith's duplicity, Anise explains that by allowing Tanith to believe he has succeeded in infiltrating their ranks, the Tok'ra hope to deceive the Goa'uld and feed them misinformation. Anise later assists the SGC in uncovering possible Zatarcs within the SGC ranks. She improperly diagnoses O'Neill and Carter, who unwittingly lied during the test to conceal their feelings for each other. Freya is attracted to Jack O'Neill, although her symbiote prefers Daniel Jackson.

Jolinar
Jolinar of Malkshur is an influential member of the Tok'ra resistance. According to Teal'c, she once led an army that was about to defeat a System Lord, until Apophis and Ra joined the fight. She appears in in the body of a Nassyan man (played by an unknown actor), before being played by Amanda Tapping as Samantha Carter. She also appears in flashback in the body of her former host Rosha, played by Tanya Reid, in and. While blended with Rosha, Jolinar carried out a romantic relationship with fellow Tok'ra Martouf/Lantash for over a century.

Sokar once captured Jolinar, imprisoning her on the hell-like prison moon Ne'tu and torturing her. She escaped by seducing Sokar's underling Bynarr and stealing the key to the prison's ring transporter while he slept. These events caused her great shame and she never spoke of them to Martouf.

In, Cronus sends an Ashrak, a powerful Goa'uld assassin, after Jolinar. She hides in the body of a Nassyan man, but is forced to transfer herself to Samantha Carter after her host is injured. The Ashrak tracks her back to Earth, where Jolinar gives up her life to save Carter. As a result of the blending, Carter gains the ability to sense Goa'uld symbiotes and control Goa'uld technology. She also acquires some of Jolinar's memories and personality, which avails her on several occasions and influences her attraction to Martouf. Samantha has since forgiven Jolinar for the forced blending.

Martouf
Martouf, played by J. R. Bourne, is a leader in the ranks of the Tok'ra. Martouf had been the mate of Jolinar, and her host Rosha, for almost a century. SG-1 first meet Martouf during their first encounter with the Tok'ra in season 2. Since Jolinar was once blended with Samantha Carter, Martouf develops an interest in her. Martouf is later present when Apophis seeks asylum at Stargate Command and recommends that the Goa'uld should be handed over to Sokar. Several months later, he joins SG-1 on a mission to rescue Jacob Carter, the host of the Tok'ra Selmak, from Ne'tu. They are captured and tortured, but Martouf,Jacob and SG-1 can escape when a new Tok'ra weapon destroys Ne'tu. However, Martouf is unwittingly subjected to Goa'uld mind control, turning him into a zatarc. His attempt to assassinate the President of the United States ends in failure, and Carter is forced to kill him.

Martouf's symbiote, Lantash, survives and is placed in a Tok'ra stasis chamber. Nearly two years later, when Lantash is still very weak, the Goa'uld attack and bombard the Tok'ra base. When his container is destroyed, the new SGC recruit Lieutenant Elliot (Courtenay J. Stevens) blends with Lantash to keep them both alive. Lantash and Elliot give their lives to save the rest of the team when they realize that Lantash does not have the strength to repair Elliot's injuries. Elliot/Lantash are left behind with a vial of symbiote poison, powerful enough to eliminate the entire invasion force. An alternate version of Martouf arrives at the SGC when many SG-1s from alternate realities start coming through the Stargate. That universe's Martouf had joined the SGC to be closer to Carter. However, their relationship did not last. According to Martouf, Carter eventually ended up with someone else, with whom she would one day have a child.

Selmak
Selmak is one of the oldest and wisest of all Tok'ra, and a member of the High Council. His first host on the show, seen in, is Saroosh, played by Joy Coghill. Saroosh had been Selmak's host for most of her life, during which she enjoyed his good company and humor. As Saroosh is dying of old age, Samantha Carter suggests to her father Jacob Carter (played by Carmen Argenziano) that he become Selmak's next host, as Selmak will be able to cure Jacob's terminal cancer. After speaking with Saroosh on the experience of being a host, Jacob agrees to the transference.

The blending of Selmak and Jacob creates a bridge between the SGC and the Tok'ra. Jacob/Selmak provides critical assistance to SG-1 on numerous occasions, including against renegade Reetou, the Goa'uld Seth, and the Kull Warriors. However, he also warns the SGC against their attempts to reverse-engineer Goa'uld technology and provoking open conflict with the System Lords by building warships. Over time, some of the other Tok'ra become concerned that Selmak is being unduly influenced by Jacob into compromising Tok'ra operations to the Tau'ri, and begin to exclude him from high-level decisions.

In, Jacob reveals that Selmak is dying of old age after living for 2,000 years. During the events of, Jacob insists that Selmak hold on so as to complete their calibration of the Dakara superweapon to defeat the Replicators. As a result of this effort, Selmak slips into a coma and can no longer exert the necessary will to save Jacob's life when he dies. Jacob tells Samantha of his intention to die with Selmak, and that he considers his years spent with him as a gift. Jacob passes away shortly after Selmak in the SGC.
