X-Men
X-Men: Instinct / Strength
Colossus
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.
Wolverine
Wolverine’s rapid regeneration powers allow him to bounce back from almost every type of bodily wound on the condition that his head remains firmly attached to his shoulders. Nevertheless, the time of each healing is understandably proportionate to the severity of the injury. His body is also immune to most poisons, drugs, and diseases; his agility, reflexes, and senses are similarly enhanced. Wolverine sees and hears things at distances far greater than those of ordinary humans. His sense of smell is even more magnified and he can recognize people and objects by scent alone, which, combined with combat and stealth training, makes him one of the world’s foremost trackers.
