Peter Rasputin, also known as Colossus, is a mutant with the ability to turn his body into an unknown form of nearly indestructible metal which grants him incredible levels of physical strength and durability. Colossus is an ideal defender of the mutant race, who had been involved in the Battle at Alcatraz Island as well as the Future War against the Sentinels.
Powers
Colossus is a very powerful mutant, able to convert his skin into an organic steel-like substance and so gaining invulnerability and superhuman strength. He is able to transform into this armor-like state at will (the process is virtually instantaneous) and remain in that form for an as yet undetermined amount of time. When he is in his human form, Colossus still wields great human strength, although it is unknown if he possesses superhuman levels of strength while in that state. However, he still has enough physical strength while in his human form to effortlessly carry a large television under one arm while walking. Colossus is completely bullet-proof and invulnerable to most, if not all, weapons while in metal form.
Superhuman Strength - After transforming into his armored state, Colossus possesses vast superhuman strength, the fullest extent of which is unknown.
Superhuman Stamina - Also, while in armored form, Colossus' musculature produces considerably less fatigue toxins than the musculature of a normal human. At his peak, he can physically exert himself at peak capacity for several days before the build up of fatigue toxins in his blood begins to impair him.
Superhuman Durability - In his armored form Colossus is invulnerable to most forms of bodily harm. His armor is capable of withstanding ballistic penetration. He can survive extremes of temperature. He can also survive falls from great heights while in his armored body.
