Fan Casting Colossus in X-Men MCU

Born to a simple farm life in Russia, Piotr Rasputin is a mutant with the ability to transform his body into steel, which grants him phenomenal strength as Colossus. He was approached by Professor Xavier with a chance to change the world for mutants as a member of the X-Men. As a gifted painter, Colossus gradually witnessed his simple life drastically change due to the adventures and complexities related to his duty as an X-Man. Even in the face of tragedies, he has maintained his role as a fighter for most of his life to build a better society for mutants and humans. Among the calamities Colossus fought, none compared to the destruction of his family. His younger sister Illyana was corrupted by the demonic sorcerer Belasco, his older brother Mikhail emerged as an insane malefactor, and his parents were slain as a result of dark schemes regarding their mutant family. Ultimately, the death of Illyana as a consequence of an infection by the Legacy Virus affected Colossus the most, leading him to embrace the philosophy of Xavier's nemesis, the mutant extremist Magneto, as one of his Acolytes. Following the fall of the Acolytes, Colossus joined Excalibur and eventually returned to the X-Men. When a cure for the Legacy Virus was developed, Colossus sacrificed himself to trigger its dissemination. However, his body was revived by Ord, an alien from the Breakworld, a world that was prophesied to be destroyed by Colossus himself. Having rejoined the X-Men, Colossus was pivotal in politically protecting Earth from an attack by Breakworld. He reconnected with his sister, the witch known as Magik, acting by her side in the X-Men. However, to demonstrate to him the effects of dark corruption, she manipulated him into becoming Cyttorak's new Juggernaut. Later, he experienced similar experiences as an avatar of the Phoenix Force and as one of the Horsemen of Apocalypse in the far future.
