Piotr "Peter" Nikolayevich Rasputin; Russian: Пётр Николаевич Распутин), also known as Colossus, is a character appearing in American comic books published by Marvel Comics. Created by writer Len Wein and artist Dave Cockrum, he first appeared in Giant-Size X-Men #1 (May 1975). A Russian mutant, he is a member of the X-Men. Colossus is able to transform himself into metallic form, making him the physically strongest of the team. He is portrayed as quiet, honest, and virtuous.
