Growing up on his parents’ farm, Piotr Rasputin saw his older brother Mikhail become a Cosmonaut. Mikhail was later discovered to be a latent mutant with energy warping powers, and to keep him secret the government faked his death. In later years, Piotr learned that he too was a mutant, and could transform his flesh into steel, but he was content to use his powers to help his fellow farmers. When a transformed Piotr rescued his sister Illyana from a runaway tractor, he was approached by Professor Charles Xavier, who was recruiting mutants for a new team of X-Men to help save his original students from the sentient island Krakoa. Dubbed Colossus by Xavier, Piotr reluctantly joined this new team, which freed the original X-Men and helped defeat Krakoa. After the battle, Piotr remained with the X-Men in America, though he found it difficult to adjust to living in a different culture.
When the X-Men visited the prehistoric Savage Land in Antarctica, Colossus saved some native women from a dinosaur. In return, the two surviving women, Nereel and Shakani, bade him join in a ritual to honor their fallen friend. Said ritual involved the creation of a new life, and though Piotr was initially reluctant, the two women persisted until he surrendered himself to their affections. Later, the X-Men were captured by the assassin Arcade, who brainwashed Colossus into believing he was the Proletarian, workers’ hero of communist Russia, and turned him against his teammates. Colossus overcame this conditioning, and the X-Men soon faced the reality-manipulating mutant Proteus, who proved to be vulnerable to metal. Seizing upon this weakness, Colossus plunged his metal fists into the heart of Proteus’ energy form, seemingly destroying him and taking Colossus’ innocence along with him. Soon after, the X-Men recruited young mutant Kitty Pryde. Despite their initial shyness, a romance blossomed between her and Colossus. Later, Arcade’s assistant Miss Locke kidnapped the X-Men’s loved ones, including Illyana, to coerce the team into rescuing Arcade from the despotic Doctor Doom. The X-Men rescued them, and Illyana remained with her brother at Xavier’s mansion. Eventually, Illyana was trapped in the demon-filled realm Limbo by its then-master, Belasco. She remained his captive for many years, though only moments had elapsed on Earth, and returned as the adolescent sorceress Magik.
Colossus and Kitty grew closer, finally admitting their feelings for one another. Colossus was among the X-Men forced by the godlike Beyonder to fight on his Battleworld. There, he fell in love with the healer Zsaji. After Colossus was killed by a cosmic-powered Doom, Zsaji gave her life to resurrect him. A heartbroken Colossus returned to Earth, ending his relationship with Kitty, though they remained friends. Colossus was later forced to take another life when the Marauders attacked the subterranean Morlocks. To save his teammate Nightcrawler, Colossus killed the Marauder Riptide; however, Riptide’s attacks caused Colossus’ bio-energy to leak from his metallic form like blood from a flesh wound. The X-Men’s then-ally Magneto attempted to heal Colossus with his magnetic powers, but was only able to close the wounds, trapping Colossus in his metal state. Recuperating on Muir Isle, Colossus later rejoined the X-Men in opposing the mystic Adversary in Dallas. When the X-Men returned to the Savage Land after it had been razed by the giant alien Terminus, Colossus was reunited with Nereel. He met her son, Peter, unaware that the boy was the result of his earlier union with Nereel.
