Piotr Rasputin grew up on a farm in Russia until Professor Xavier recruited him to join the X-Men. He is a loyal teammate, using his powerful armored form to protect his comrades in battle. His great physical strength conceals his quiet soul as an artist.
Piotr has an on-again, off-again romantic relationship with fellow X-Man Kitty Pryde. His sister, Illyana Rasputin, is the mutant sorceress known as Magik.
