X-Men No More
Upon his return from a battle with the mutant, Fitzroy, Peter Rasputin, better know as Colossus, arrived home to discover the death of his sister, Illyana. Feeling betrayed by a world that feared and hated him, he began to doubt in Professor Xavier's dream of peace between mutants and humans. Colossus joined forces with Magneto's Acolytes believing that perhaps their belief in mutants as the superior being was the right choice.
