Piotr “Peter” Rasputin was born on a Soviet collective farm called the Ust-Ordynski Collective near Lake Baikal in Siberia. He lived there with his mother Alexandra, father Nikolai, and sister Illyana. His older brother, Mikhail, had been a Soviet cosmonaut and had apparently died in a rocket accident. the 2006 comic mini-series Colossus: Bloodline established that the family was descended from a real-life historical figure, Grigori Rasputin. Peter’s superhuman powers manifested during his adolescence while saving his sister from a runaway tractor. Immediately after, Peter was contacted by Professor Charles Xavier, the founder of the X-Men.
