Universal Annihilation Army Warstar

The Universal Annihilation Army Warstar (宇宙虐滅軍団ウォースター) are the first set of fictional antagonists of the thirty-fourth Super Sentai Series Tensou Sentai Goseiger, that battle the Goseigers in order to destroy the Earth. Following an insect theme, the name of each member's home world being an anagram of the type of Earth insect they represent, all Warstar-related members and things have names that are modifications of the Japanese names of American Science fiction films. "Warstar" itself is from Star Wars (スターウォーズ). Most of Warstar is defeated in episode 15, with only a handful of members remaining to take revenge in Tensou Sentai Goseiger: Epic on the Movie.

Fictional history
Warstar's forces are based on the Universal Mothership Indevader (宇宙母船インデベーダー) and seek to steal the life force of other planets with their insect-based forces. Before their invasion of Earth, they realized that the Gosei Angels would be trouble for them, so they destroyed the Heaven's Tower (天の塔) in a pre-emptive strike. Unbeknownst to them, five Gosei Angels were living on the Earth at the time. Eventually, Warstar is defeated when its leader and base are destroyed by the Goseigers.

Mons Drake
The Great King Mons Drake (大王モンス・ドレイク), also known as Mons Drake of the Planet (惑星のモンス・ドレイク), is a Monsu Alien (モンス星人) who is the leader of Warstar armed with the Doreiku Tomahawk (ドレイクトマホーク). His signature attacks are the Planet Bullet (惑星弾), the Syzygial Bullet (惑星直列弾), and his most powerful attack being the Gravity Fall (引力落とし) ceremony where he uses the dark matter in his body to cause a nearby satellite to impact the planet he is currently on. Before invading the Earth, informed by his new follower Buredoran of the Gosei Angels and the threat that they posed in his plans, Mons Drake tasks Dereputa to destroy Heaven's Tower in a preemptive strike in an attempt to bar the Gosei Angels from Earth. However, as five Gosei Angels were on the planet at the time, Mons Drake is forced to have his forces deal with them. Eventually, after growing tired of the Goseigers' interference, Mons Drake performs the Gravity Fall ritual to make the Moon collide with Earth. However, the ceremony is stopped by the Goseigers with Dereputa seemingly killed off. Soon after, Mons Drake attempts another plan by transferring Earth's oxygen into the Indevader and have it crash into the Earth to burn every human. However, he is instead blasted into the Indevader by Hyper Gosei Great and consumed in the resulting explosion. His spirit later appears to Brajira, futiley trying to attack him before being cast away. Mons Drake's name comes from Star Trek (スタートレック).

Mons Drake is voiced by Shōzō Iizuka (飯塚 昭三).

Dereputa
Dereputa of the Meteor (流星のデレプタ) is a Zutinma Alien (ズティンマ星人) who was a footsoldier until his fighting spirit attracts Mons Drake's attention, making him a combat commander and his right-hand man. His signature attacks are the Meteor Bullet (流星弾) (using his forearms to unlease an energy blast), Super Meteor Bullet (超流星弾), Meteor Dimensional Bullet (流星縦横弾), and Super-Galactic Meteor Bullet (超銀河流星弾). He was the one who destroyed Heaven's Tower when Warstar began its invasion on Earth, thus becoming Gosei Red's nemesis after severely injuring his forearm in their initial confrontation. However, when Mons Drake pushes the Gravity Drop forward, Dereputa barely survives Hyper Gosei Great's attack and is presumed dead. However, discarding his breastplate with a scar on his chest from the attack, Dereputa came to the realization of acting on his own to prove his superiority. After Mons Drake's demise, Dereputa resurfaces to settle things with Gosei Red while attacking his teammates to ensure no interference. Though finally defeated, Dereputa unknowingly releases the Yuumajuu. Dereputa's name comes from Predator (プレデター).

Dereputa is voiced by Rikiya Koyama (小山 力也). Koyama is known for his role as Joe the Haze in Kamen Rider Black RX.

Buredoran
Buredoran of the Comet (彗星のブレドラン) is a treehopper-like alias adopted by Brajira after he arrived to the present era as the Indevader arrives to Earth, managing to become one of Mons Drake's top commanders while providing Warstar with intelligence on the Gosei Angels that led to the destruction of Heaven's Tower. Fighting the Goseigers personally whenever their Tensou Techniques or weaknesses are exploited, Buredoran uses the Buredolancer (ブレドランサー) along with his signature attack Comet Bullet (彗星弾), firing an energy blast from his hand. He is in charge of making the monsters enlarge by using the Bibi Bugs. Buredoran pilots the Indevader prior to its destruction, and survives to resume his Yuumajuu guise, though he does briefly return to his Warstar form during the events of Tensou Sentai Goseiger: Epic on the Movie. Buredoran's name comes from Blade Runner (ブレードランナー).

Buredoran is voiced by Nobuo Tobita (飛田 展男).

Gyōten'ō
Gyōten'ō of the Supernova (超新星のギョーテンオー) is a Doditake Alien (ドッディテケ星人), referring to himself as Warstar's strongest officer. One of the last remaining members of Warstar after Monsu Doreiku's destruction, Gyōten'ō has been hunting for the Horn of Ragnarok on another planet. He appears in Tensou Sentai Goseiger: Epic on the Movie, managing to achieve the weapon and swallowing it once the end of the world is assured. Though he damages the Dragon Headder prior to enlarging, Gyōten'ō is destroyed by Wonder Gosei Great with the Horn shattered in the process. Gyōten'ō is named after Captain EO (キャプテンEO).

Deinbaruto is voiced by Bin Shimada (島田 敏).

Bibi
The poisonous Bibi Bugs (ビービ虫), are living products from the dark aspects of previous alien races Warstar conquered. After Warstar fell, Brajira kept the Bibi Bugs' hive to utilize them for the Yuumajuu before Kinggon takes it. When Kinggon was destroyed, the Bibi Bug Hive ended up in Metal-Alice's possession, modifying them to convert into Bibi Nails to enlarge Matroids. Eventually the Bibi Bugs are destroyed after Brajira's death. However, one Bibi Bug survives and evolves into a humanoid form called King Bibi (キングビービ) who enters the body of Yumeko Hoshino in order to execute a master plan that would destroy the Goseigers and everything they stood for in order to avenge his kind while feeding on the darkness in human hearts. However, King Bibi's plan fails and he is destroyed soon after by Ground Gosei Great.

The Demon Bug Soldiers Bibi (魔虫兵ビービ) are foot soldiers that were originally dolls that are given life through the Bibi Bugs, and armed with various weapons. Originally used by Warstar, the Bibi Soldiers were used by the other organizations.
