- "I should have left you in the self-pitying mess I found you in. But this is what friends do. They show up! Not when convenient or easy. When hard."
- ―Colossus to Deadpool
Colossus (born Piotr Rasputin, also known as Peter Rasputin) is a mutant who can cover his entire body in an incredibly dense, organic metallic layer, which grants him incredible levels of physical strength and durability.
Peter Rasputin was born in 1986 during the Chernobyl disaster in Soviet-era Russia which caused a number of mutant infants to manifest their abilities at such an early age. He later immigrates to the United States and enrolls in Xavier's School for Gifted Youngsters.
Colossus is seen as a student sketching in the school's courtyard.
- "I can help you."
- ―Colossus and Wolverine
Colossus is still a student with an interest in art. Later that night, HYDRA forces under William Stryker's command infiltrate the X-Mansion, with Siryn's sonic scream immobilizing them and intruders and alerting the rest of the sleeping students. 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. Wolverine kills many of Stryker's men, while Colossus, Rogue, Iceman, Pyro, and most of the students escape through hidden tunnels.
After the events of Alkali Lake, he returned to the Institute along with all the other students.
- "Hey, Pete. You seen Rogue?"
"Yeah, she took off."
- ―Iceman and Colossus
By this point, Colossus is a member of the X-Men and joins his teammates in the Danger Room with the rest of the X-Men. Some of the X-Men and the students are fighting in some apocalyptic battle. Enemy fire blasts buildings around them and everything's in flames. The students are running through the chaos, and Storm flies, avoiding getting hit. Rogue and Colossus are about to get hit by a huge flying rock, but Peter turns to steel, touches Rogue's head to transfer his powers to her, and stands in its way, sending the rock flying at Wolverine's direction, hitting him in the head. Logan simply heals himself and looks at his students in disappointment – the world in turning to hell, and they just pretty much sit around. He calls them to follow him, and they run after him.
They realize that the enemy is flying straight at them at high speed from the sky, and Logan gives up on his students. He pops his claws and calls to Colossus, telling him to throw him at the enemy. Colossus turns to steel again and tosses Wolverine at the enemy, despite Storm's objections. A big clash is heard, and then a destroyed Sentinel head falls from the sky, with Logan on it. The enemy disengaged, Wolverine dismisses the class. The Danger Room returns to normal, as Logan compliments Peter on his throw.
The next day, outside on the front yard, Ororo Munroe is eulogizing Charles Xavier in a memorial service in front of all his students: "We live in an age of darkness," she says, "a world full of fear, hate and intolerance. But in every age, there are those who fight against it. Charles Xavier was born into a world divided, a world he tried to heal – a mission he never saw accomplished. It seems the destiny of great men to see their goals unfulfilled."
At Professor Xavier's funeral, in the crowd sit Marie D'Ancanto, Bobby Drake, Kitty Pryde, Peter Rasputin, Hank McCoy and many other students and friends of Xavier's. Logan isn't sitting with them, as he is standing and listening from afar, a loner as always. Rogue looks at him, as Ororo continues her eulogy: "Charles was more than a leader, more than a teacher, he was a friend. When we were afraid he gave us strength, and when we were alone he gave us a family. He may be gone, but his teachings live on through us, his students". Ororo finishes: "Wherever we may go, we must carry on his vision, and that's a vision of a world united." Logan walks away. All other people present stand up, and Kitty walks to his memorial and puts a flower on it.
When Iceman was looking for Rogue, Colossus walks by carrying a TV, and Bobby asks him if he's seen Rogue. Peter tells him he has – she took off. Confused, Iceman walks away.
After the President fails an attempt to stop Magneto, the X-Men plan to take this into their own hands and stop Magneto themselves. They meet up with Storm, Iceman, Shadowcat and Colossus, and Bobby reminds Logan that there are only six of them. Wolverine pauses and tells the young students that he won't lie to them – they're outnumbered, they lost Scott, they lost the professor – but if they don't fight now, everything these men stood for will die with them, and he's not gonna let that happen. Iceman nods in agreement, and Logan says they stand together, X-Men, all of them. Bobby looks at Kitty and Peter, and they both sign they're ready. He then turns back to Logan and tells him they're in. Ready for the battle of their lives, the X-Men walk towards the Blackbird.
When the remaining members of the X-Men arrive at Alcatraz Island, the Blackbird lands on the roof. Lightning falls on the battle scene as Storm descends from the sky. Next, Beast jumps from the roof and lands like a true animal. Iceman and Shadowcat jump together, phasing into the ground to avoid getting squashed, and then phasing right back up. Colossus jumps down too, his metal form protecting him. Lastly, Wolverine jumps down the wall, using his claws to scratch the wall and slow down his fall. Storm lands too, and Wolverine yells to the humans to go back and lock the doors. He then orders the X-Men to stand together and hold a line. Instantly, the six mutants line up in front of the Brotherhood to form a strict line of defense, ready for the battle of their lives.
After the battle, Colossus came back to the school with all the other students, the Institute run now by Storm.
Colossus is one of the very few surviving mutants in the dystopian 2023. He, along with Blink, Warpath, Iceman and Sunspot are seen holding off the attacking Sentinels in Moscow in order to buy time for Shadowcat to send Bishop's consciousness to the past so they could regroup in China. After they have all taken battle positions, A Sentinel drills through the base and lands in front of them. Before it could do anything, however, Sunspot sets it on fire, immobilizing it. Another comes down and initially overpowers Colossus, but Warpath, with Blink's help, intervenes and attack it. Though the Sentinel threw Warpath off, Colossus recovered and beat down the Sentinel.
Colossus fends off a Sentinel, but as he throws a punch, the Sentinel grabs the punch and absorbs his powers, thus mimicking Colossus' organic steel flesh and uses his own powers against him. The robot then proceeds to tear off Colossus' arm and beat him to death by smashing his head into the ground. However, Kitty was able to successfully complete her task with Bishop and the event never took place.
With the timeline altered, Colossus is seen alive and well again in China. He is present in the monastery when the team decides to send Wolverine back into his past body in 1973 to change the events in their present. Once again, Colossus helps the team with fighting the approaching Sentinels to allow Kitty to hold Wolverine's consciousness in the past just long enough to complete his mission.
After Warpath detects 12 Sentinel carriers inbound, 10 miles, Storm creates a snowstorm and Magneto then lifts the X-Jet and sends it flying towards the Sentinels. Storm then fires a lightning bolt into the engine and the jet blows up, destroying most of the Sentinels. The remaining mutants take cover from the incoming Sentinel and X-Jet pieces, with Colossus transforming into his metal form, and Magneto stopping the incoming pieces. Magneto, however, is stabbed with a piece of shrapnel. Storm turns around towards him, only to be stabbed in the back by a Sentinel and thrown off the cliff. Dozens of Sentinels then attack, with the X-Men fighting to the last man.
Blink sends out a portal that sends Colossus into the sky. He then goes through another portal after building up enough momentum and punches right through a Sentinel. As he fights the Sentinels, becomes overwhelmed by their assault as he goes to punch a Sentinel but it jumps over him and grabs his arms as another grabs his legs and they pull until he is brutally ripped in half from the waist down, while still in his armored form.
- "Wade, you're better than this. Join us. Use your powers for good. Be a superhero."
"Listen! The day I decide to become a crime-fighting shit swizzler, who rooms with a bunch of other little whiners at the Neverland mansion of some creepy, old, bald, heaven's gate looking motherfucker...on THAT day...I'll send your shiny happy ass a friend request. But until then, I'm going to do what I came here to do. Either that, or slap the bitch outta you."
- ―Colossus and Deadpool
After learning about the mercenary known as Deadpool, Colossus had attempted to convince him to use his powers for good and join the X-Men. One day while eating cereal in the X-Mansion, Colossus spotted Deadpool on the news, causing mayhem on a bridge. Taking the X-Jet, Colossus and his student, Negasonic Teenage Warhead, stopped Deadpool from killing an injured Ajax, allowing the villain to escape in the process. Enraged, Deadpool tried to attack Colossus, only to break most of his limbs. Colossus then handcuffed the mercenary, planning to take him to Professor X. However, Deadpool escaped by cutting his cuffed hand off.
Later, Deadpool enlisted the help of Colossus and Negasonic Teenage Warhead in order to rescue Vanessa Carlysle from Ajax. During the ensuing fight on a decommissioned aircraft carrier in a junkyard, Colossus confronted and fought Angel Dust. Using her powers, Negasonic Teenage Warhead saved Colossus from getting strangled with a metal pipe. After managing to get his student and Angel Dust to safety, Colossus attempted to convince Deadpool into sparing a mortally injured Ajax. However, despite his speech about the virtues of being a hero, Deadpool killed the villain. Although disgusted, Colossus and Negasonic Teenage Warhead leave as Deadpool and Vanessa reunite.
When Deadpool blew himself up after the death of Vanessa Carlysle, Colossus collected Deadpool's body parts and took him to the X-Mansion to recover. While there, Colossus managed to convince Deadpool to join the X-Men. Colossus, Negasonic Teenage Warhead and Deadpool responded to a call about a mutant running wild at the Essex House for Mutant Rehabilitation. While there, Deadpool managed to talk the mutant – Russell Collins – down but then proceeded to kill members of the orphanage staff after realizing that they had abused the boy. Deadpool was arrested and Colossus was shocked and disappointed, especially given that Wade committed these murders on live television in an X-Men trainee uniform, essentially tarnishing the X-Men name as well as worsening mutant-human relations in general.
Sometime later, Deadpool tried to apologize to Colossus by standing outside his window blasting a song. Colossus ignored Deadpool's efforts but eventually decided to help him. Taking Negasonic Teenage Warhead and Yukio, Colossus headed to the Essex House to help him stop Juggernaut and Russell. Colossus fought Juggernaut, eventually resorting to fighting dirty. He was helped by Yukio and Negasonic, finishing the fight by electrocuting Juggernaut in a pool of water.
When Wolverine wakes up in the Xavier Institute, he sees Colossus alive again in a classroom standing next to Kitty as she gives a presentation to other students.
In 2028, Charles Xavier developed Alzheimer's and suffered a massive seizure that injured 600 people, and killed several members of the X-Men. It is unknown if Colossus was among those who were either killed or injured.
- "I haven't always been the best friend to you. But you've always been that to me. So thank you."
- ―Deadpool to Colossus
Despite his fearful appearance and his hulking powers, Peter/Piotr is a kind and gentle soul, always disposed to help the younger students of the Institute and ready to put his strength at the service of whoever needs it. In the original timeline, the teenage Colossus had a talent for art and somewhat a cheeky sense of humor. He is seen with Flea laughing at a picture he sketched of Iceman and Rogue kissing.
In the revised timeline, Colossus seems to have an honorable nature as he constantly tries to urge Deadpool to join the X-Men and encouraging him to spare Ajax. He is also extremely respectful to women, choosing not to hurt Angel Dust until he was forced to and also covered his eyes when he saw Angel Dust's breasts. Colossus seems to dislike obscene or explicit displays as shown when he displays a distaste for Deadpool's violent actions and swearing.
Powers, Abilities, & Weaknesses
- Organic Steel Form/Metal Exoskeleton - 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.
- Superhuman Strength - 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.
- 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. 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.
- Superhuman Durability - 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.
- Skilled Combatant - 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.
- Physical Education Teacher - 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.
- Skilled Pilot - Colossus is capable of piloting the X-Jet.
- Skilled Artist - 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.
- Blood-Injury Phobia/Blood Sensitivity - After Colossus witnessed Deadpool kill Ajax, he began vomiting at the sight of Ajax's blood.
- Chivalry - Colossus is extremely chivalrous as shown when he is hesitant to fight Angel Dust and gets sucker-punched after averting his eyes from the villain's exposed breast.
- Extreme Force - Despite his armored skin, the Sentinels were strong enough to inflict a fatal dent to his skull and two of them were capable of literally ripping him in half. Juggernaut was able to use his immense strength to hurt Colossus, denting his body and even knocking a tooth out.
- Strangulation - Angel Dust was able to use her great strength and bend a metal pole around Colossus's neck, and the mutant would've suffocated, if not for Negasonic Teenage Warhead's intervention.
- Magnetism - Due to being made of metal in his armored form, he still vulnerable to all effects that would affect normal metals, including Magnetism.
- Unconsciousness - If he is rendered unconscious, he spontaneously reverts back to his normal form.
