History:
Peter Rasputin is a mutant with the ability to turn his entire body into a sort of organic steel, granting him tremendous strength and durability. He was a student at Xavier's School for Gifted Youngsters. When William Stryker's military forces attacked the X-Mansion, Peter used his strength to help many of the younger students to escape. He became a member of the X-Men and fought alongside Storm, Wolverine, Beast, Iceman, and Shadowcat when Magneto attacked Alcatraz Island to destroy the mutant 'cure'. He proved vital in the defeat of Magneto, throwing Wolverine to distract Magneto until Beast could inject Magneto with the cure. Peter would later be among the last of the mutants in the original timeline with the advent of the Sentinels Mk. X. In Moscow, the Free Mutants came under attack by 2 Sentinels, who proceeded to kill the mutants off except for Bishop and Kitty, with Peter dying when his head was crushed while in metal form from a Sentinel with denser metal than him. When Bishop and Kitty were successful in rewriting the immediate past, Peter and the slain Free Mutants were revived by timeline retcon. They then head to an abandoned monastery in China, along with the last of the X-Men, to change the past in 1973 with Wolverine, with Peter among the defenders stationed outside. Eventually, the gathered mutants clashed with the Sentinels, with Peter dying once again by being ripped in half by the waist from two Sentinels' tugging. Then, Wolverine created a new timeline by going back to 1970s to prevent Mystique from assassinating Bolivar Trask. Here Colossus was again a member of X-Men and became a teacher at Xavier's School for Gifted Youngsters. Sometime later, Colossus tried to recruit Deadpool into the X-Men. He tried on multiple occasions because Colossus believed Deadpool should use his extraordinary abilities for good. On one occasion, he and his X-Man trainee Negasonic Teenage Warhead tried to apprehend Deadpool and bring him to Professor X. They interrupted Deadpool as he was attacking the convoy of mutant criminal Ajax. Deadpool was furious that they allowed Ajax to escape, so he didn't go along with them. Much later, Deadpool enlisted their assistance in rescuing his ex-girlfriend from Ajax. Colossus and Negasonic Teenage Warhead fought off Ajax' right-hand woman, Angel Dust. They managed to defeat her together, while Deadpool was able to defeat Ajax and rescue his ex-girlfriend. Deadpool had Ajax crippled on the ground, and Colossus pleaded for Deadpool not to kill him. Deadpool killed him anyway because he found Colossus' heroic speech too long. Colossus and Negasonic Teenage Warhead parted ways with Deadpool afterwards, with Angel Dust apprehended. Sometime later, after Deadpool's girlfriend was murdered, he tried to kill himself multiple times because of depression. When Deadpool explodes himself, Colossus took the pieces of his body and led him to the mansion X to convince him to be part of the X-Men. After Deadpool accepts participate of the team, Colossus, Negasonic Teenage Warhead and him participated in a mission in the Essex House for Mutant Rehabilitation, Russell Collins became furious and and wanted to take revenge on members of the orphanage staff, Deadpool kill they and was arrasted with the boy. Sometime after, Deadpool asks for help from Colossus to stop Russell and Juggernaut. He fight against Juggernaut with the help of Negasonic Teenage Warhead and Yukio.

Powers:
 Colossus can convert the tissues of his entire body into an organic, steel-like substance. This substance resembling steel is of an unknown composition, but appears to be analogous to osmium and to carbon steel. 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. Once in his armored form, he remains so until he consciously wills himself back to normal. While in the armored state, Colossus possesses the same degree of mobility that he does in his normal form.  After transforming into his armored state, Colossus possesses vast, inhuman strength, allowing him to send people flying with one arm, break stone or dent metal effortlessly, and is immune to the strength of regular humans and even most superhumans. Only the Mark X Sentinel's, Angel Dust, and Juggernaut have been able to match him in strength or overpower him. Even without his metal form, he broke through a wall effortlessly with his fist and carry a very large TV under one arm whilst walking. His strength level was roughly 70 tons as a teenager growing up in the USA. In the revised timeline he appears to have trained harder and is older, allowing him to be capable of pressing 100 tons.  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. He was unfazed by touching Rogue and could give her his armor abilities for as long as she touched him, without any visible cost to himself.  In his armored form, Colossus is completely bulletproof and invulnerable to most forms of bodily harm. He can survive extremes of temperature. He can also survive falls from great heights while in his armored body. Unlike most characters, Colossus demonstrates a significant resistance to Rogue's absorption abilities. Most victims are left nearly powerless and weak. Colossus simply shrugged off the effect and immediately used his powers to throw Wolverine at a Sentinel. He is also completely unaffected by Negasonic Teenage Warhead's explosion at full power despite the heavy collateral damage it caused and it knocking out Angel Dust.   Colossus is an extremely skilled and formidable fighter. He was able to keep up with the Sentinels and was skilled enough to almost defeat in combat Angel Dust, who is an extremely skilled fighter in her own right. He showed his advanced combat skills with his fight against Juggernaut, outmaneuvering him but was eventually overwhelmed because of his opponents' greater strength.  Colossus seems to have a good understanding of physical health and diet as he trains the younger X-Men, such as Negasonic Teenage Warhead. This is notable when Colossus advises her on not skipping breakfast and eating a protein bar after a good work out.  Colossus is capable of piloting the X-Jet.  Colossus is seen sketching outside the mansion in the first film, he is also seen sketching an intricate picture of Iceman and Rogue having an unfortunate outcome of their kiss.
