List of X-Men (TV series) characters
This is a list of characters from the animated series "X-Men". Hero teams. X-Factor. X-Factor is the mutant U.S. government group that was most notably seen in the episode "Cold Comfort". However, X-Factor also could be seen briefly in episodes Sanctuary Parts 1 and 2. Alpha Flight. Alpha Flight was seen in the episode "Repo Man." Vindicator (who had renamed himself Guardian in the comics) and the Canadian Alpha Flight capture Wolverine. The Canadian government demand their project back. Either he joins their team as originally planned or they  repossess his indestructible, adamantium skeleton. The Mutant Resistance "(in the Xavier-less time-line)". This was the team created by Magneto in an alternate time-line after Xavier was killed in early life in the episode "One Man's Worth," in which the humans and mutants were locked in a war. Neutral characters. Neutral groups. Starjammers. The Starjammers appear in the five-part episode "Phoenix Saga" led by Corsair (Major Christopher Summers). In this episode, the Starjammers attack the X-Men and steal the M'Kraan crystal, in hopes of trading in to D'Ken so that Corsair can get close enough  to kill him. However, D'Ken knew of their plan and tricked them, and got hold of the M'Kraan crystal. The Starjammers have to work with the X-Men to destroy D'Ken. Hepzibah, Raza Longknife, Ch'od, and Cr+eee were the Starjammers that appeared along with Corsair in the "Phoenix Saga." Corsair later appeared in the episode "Orphan's End." In this episode, Corsair is on the run from a corrupt Shi'ar police officer, and he comes to Earth. Later, he finds out that Cyclops is his son. They first accuse Storm of being a traitor and attack her, but after she  explains to the Starjammers what was happening they help Cyclops and Corsair defeat the officer. Acolytes. The Acolytes appear in the "Sanctuary" storyline, in which Magneto builds Asteroid M as a safe haven for all mutants to live away from the hatred of baseline humans. The Acolytes, led by Fabian Cortez, aid Magneto in the liberation of the Genoshan mutant slaves from the hands of the Genoshan magistrates. After Cortez betrays Magneto and he is believed to have been killed by the X-Men, the Acolytes pledge their loyalty to Cortez, though they turn on him after he is later  exposed. Morlocks. When the Morlocks captured Cyclops and Jean Grey, Storm led the X-Men to rescue them. In the end, after a duel between Storm and Callisto, not only did the X-Men get Cyclops and Jean back, Storm also earned leadership of the Morlocks. They later appear in the episode "Out of the Past," where the Morlocks are captured by Lady Deathstrike and the Reavers and she unleashes an alien. The X-Men saved the Morlocks and defeated the alien. Shi'ar Imperial Guard. The Shi'ar Imperial Guard appeared in the episodes "Phoenix Saga" and "Dark Phoenix Saga." In  the "Phoenix Saga," the Imperial guards track down Lilandra and the M'Kraan crystal, following D'Ken's orders, but after D'Ken fuses with the M'Kraan crystal and Lilandra becomes empress, the Imperial guards help the X-Men and the Starjammers defeat D'Ken. Later, in "Dark Phoenix Saga," the Imperial guards seek to destroy the Phoenix after she destroys a star system, but unlike the comics, the star system was deserted. So they go to Earth to stop Phoenix from destroying further systems. Assassins Guild Villains. Villain teams. Brotherhood of Evil Mutants. The Brotherhood of Evil Mutants in this series is based  on the third incarnation of the team from the comic books. The group is led by Mystique, with the Blob, Avalanche, and Pyro as members of the group, and Rogue being shown as a former member. The group is revealed to have been initially financed by the mutant Apocalypse, though only Mystique knew this. Notably absent from the series was the Brotherhood member and Mystique's longtime lesbian lover, Destiny, who was a major member of the team in the comics. As such, major changes were made towards the series' adaptation of "Days of Future Past" storyline, in which Destiny  played a major role during the climax of the story. Nasty Boys. While the Nasty Boys are barely a passing blip in the extensive history of the "X-Men" comics, the villainous team was featured several times in the series. Appearing first in the episode "Til Death Do Us Part (part 2)," the series featured four of the Boys: Ruckus, Gorgeous George, Hairbag, and Slab. The X-Man Morph, who had been resurrected by Mr. Sinister, had an "evil" side to his personality. "Evil" Morph was often a part-time member of the Nasty Boys, but Sinister increasingly lost control  of him. The Nasty Boys reappeared in both parts of "Reunion," where, teamed with the Savage Land Mutates, they proved to be quite imposing to the X-Men, whom Sinister had rendered powerless. The X-Men eventually regained their powers, freed Morph from Sinister completely, and defeated Sinister and the Boys. After leaving the Savage Land, the Boys reappeared with Sinister in all four parts of "Beyond Good and Evil." Vertigo apparently accompanied them (Sinister had given her a Magneto-inspired energy boost in "Reunion") and was made into a member, despite her female status. Savage Land Mutates. Savage Land  Mutates were the creations of Magneto, though they were later recruited by Mr. Sinister. Inner Circle Club. The Hellfire Club appeared in the "Dark Phoenix Saga" storyline, though it was renamed Inner Circle Club to prevent controversy regarding the use of the word "hellfire", which could have prompted accusations of satanism. The Inner Circle's leaders aim to control Jean Grey and brainwash her into believing herself to be the Queen of the Inner Circle, though they only manage to unleash the Dark Phoenix. Horsemen of Apocalypse. The Four Horsemen of Apocalypse were the same ones as in the "X -Factor" comics. The lineup was composed by mutants that submitted themselves to the so-called mutant "cure," developed by Dr. Adler (Mystique in disguise). The cure process transformed the four mutants: Autumn Rolfson (Famine) (voiced by Catherine Gallant), Plague (Pestilence), Abraham Kieros (War) (voiced by James Millington), and Angel (Death) into altered mutants under the control of Apocalypse. The four-part episode "Beyond Good and Evil" featured another team of Horsemen, created by Apocalypse during his time in Ancient Egypt. The style of these Horsemen reflected their Egyptian origins. Reavers. The Reavers appear alongside Lady Deathstrike when she goes down  to the Morlock's tunnel and tricks Wolverine into coming down there, hoping to get him to open an alien ship that she found in the tunnel. When the ship is opened, an alien comes out of the ship and sucks the life out of the Reavers. So Lady Deathstrike has to work together with Wolverine to defeat the alien. In the end, the X-Men defeat the alien and all the Reavers' life energy is sent back to their bodies. Weapon X. The Weapon X program was responsible for Wolverine's adamantium endoskeleton and fabricated memories. The program was  directed by the Professor and Dr. Cornelius. Weapon X captured the four members of Team X (Logan, Victor Creed, Maverick, and Silver Fox) in order to brainwash them to become an elite team of mind-controlled assassins. However, Wolverine escaped and his rampage through the Weapon X headquarters allowed Creed, Maverick, and Silver Fox to escape. Mojo's Trackers/Wildways. Besides Spiral, Mojo employed a number of agents and servants. The Colony/Brood. The Colony appear in the episode "Love in Vain" in a New Mexico desert. Wolverine witnesses the crash of a spaceship carrying horrific, alien bug-like creatures , the Colony, which overwhelm him. They differ from their appearance in the comics as these Brood are human sized with greenish skin and could fire electrical energy blasts from their tails. They also had four mechanical tentacles similar to Doctor Octopus and had an anti-gravity generator that allowed them to fly. People would be infected by spores and would turn into drones for the Colony. They also had red eyes and appeared similar to the Xenomorphs from the "Alien" movies. Children of the Shadow. The Children of the Shadow appeared in the episode "Secrets, Not Long Buried" when Cyclops  flies solo to Skull Mesa, a tiny western desert community of mutants and humans to see an old friend Dr. Prescott and his plane is blasted out of the sky. Injured and rendered powerless, he struggles into town only to discover his friend is missing and the town is caught in the grips of a criminal mutant group called the Children of the Shadow. The group hunts him down, seeing he is vulnerable because they have temporarily removed his powers and he is opposing them. As they try to make an example out of Cyclops his words get others to  help and he recovers his powers from the healing aid of one of them, along with some other mutants Cyclops defeats them.
