Piotr Rasputin AKA Colossus has the ability to change his body's tissue into an organic, steel-like material. This gives him superhuman strength (he can lift at least 70 tons) and protects him from injury. Colossus is also a talented artist, he only reluctantly agrees to use his powers in combat, feeling it is his responsibility to use his abilities for the betterment of human and mutant-kind.
Colossus joined the X-Men. Colossus trained with Shadowcat and Nightcrawler when Wolverine messed the three up and left them hanging once they were captured by him. Once Jean Grey blew up the Xavier Mansion, Colossus left the X-Men. He returned to Russia to be with his family. When Wolverine reformed the team, Colossus turned down the offer because he did not want to leave his family again,thus not returning to the x men again.
- Colossus was voiced by Phil Morris.
- Colossus's real name was changed from the Russian Piotr to the English Peter.
- Colossus was supposed to return following the explosion but the producers decided against it. He was supposed to return for the proposed second season before the series was cancelled.
