Piotr Rasputin (Earth-8096)

Peter Rasputin or Colossus is a mutant with the ability to turn his body into an unknown form of metal which grants him incredible levels of physical strength and durability.

Foresight
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.
