Peter Rasputin, also known as Colossus, is a mutant with the ability to turn his body into an unknown form of metal which grants him incredible levels of physical strength and durability.
Colossus is a student at Xavier Institute's, he was sketching in the courtyard.
- "I can help you."
- ―Peter Rasputin[src]
When the X-Mansion was being attacked by Stryker's soldiers Peter used his metal body to stop the soldiers and attacked two of them, punching them through a wall, so rescuing Siryn. He finds Wolverine and says that he could help him but he replies that he should help the kids that are running away from the X-Mansion. So, he leads them out of the mansion to the forest using a secret passage.
After the events of Alkali Lake, he returned to the Institute along with all the other students.
Peter was in the Danger Room with the other students under Wolverine's teaching. The simulation is a fight with a Sentinel and Colossus is fighting to the side of Rogue. When the Sentinel attacks them, Rogue absorbs his powers and covers them both from the attack with her (temporal) steel body. When Wolverine has enough of the training, he calls him, referring at him as "Tin Man", and makes him throw him to the giant robot, decapitating it and so ending the simulation.
As an X-Men recruit and student, Colossus assisted at Xavier's funeral. After the ceremony, when Wolverine had come back from Magneto's base, he, along with Iceman and Kitty Pryde, joined his teachers in the fight at Alcatraz Island. During the battle, his power proved to be quite useful, since he was able to defeat every single opponent he faced. Eventually, he threw Wolverine at Magneto, making a distraction and permitting Beast to inject him with the cure.
After the battle, Colossus came back to the school with all the other students, the Institute run now by Storm.
Peter, Iceman, and Kitty Pryde met up with fellow survivors Bishop, James Proudstar, Blink, and Sunspot. They formed a way to survive; Warpath detected a Sentinel group and alerted Kitty and Bishop. While the group fought off the Sentinels, Kitty sent Bishop's consciousness back a few days ago to warn them of the attack. This went on for a while as they travelled the world. During the opening battle Colossus managed to beat down one of the Sentinels and attacked another, only for his punch to be caught by the Sentinel and had his arm ripped off and then was killed by a curb stomp but the death was erased thanks to Kitty and Bishop.
They eventually met their old teachers Storm, Charles Xavier, Magneto and Logan in China, where they decided to send Logan's consciousness back in time to change the past. Colossus waited outside with the other X-Men to wait for the Sentinels to come.
Warpath sensed twelve Sentinel ships approaching and the X-Men prepared to fight. Storm and Magneto took out most of the Sentinels, but some survived and began to fight viciously against the X-Men. Colossus, in his metal form, attempted to fight a Sentinel, but was overpowered by another and ripped in half by two Sentinels.
When Logan woke up in the new timeline of 2023, Colossus was seen with Kitty teaching a class to younger mutants.
Despite his fearful appearance and his hulking powers, Peter is kind and gentle, always disposed to help the younger students of the Institute and ready to put his strength at the service of whoever needs it.
Powers and Abilities
Colossus is a very powerful mutant, able to turn his skin into an unknown metal and so gaining invulnerability and superhuman strength. When he is in his metal form, Colossus has enormous strength, the fullest extent of which is unknown. 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.
