As one of the most physically powerful mutants in Colossus has some powerful relatives. From his sorcerer sister to his long-lost son to his monstrous great-grandfather, Colossus is tied into one of Marvel's most fascinating bloodlines - one that also connects him to one of X-Men's biggest villains.

We're ranking the 13 most powerful of Colossus' family according to their offensive abilities, while also uncovering the dark truth of the ancestor who binds them all together. Colossus' extensive family tree is no coincidence, and the history of his family is the story of a single dark plot warping multiple generations.

13 Yuri Grigorievich

Colossus' Distant Cousin Was a Beloved Healer

Introduced in David Hine and Jorge Lucas' X-Men: Colossus - Bloodline, Yuri was a minor mutant healer who used his powers in service of a small Siberian community. While Yuri was known by everyone in his region as 'the Healer,' he was a relatively low-level mutant in global . Sadly, this meant that when Mister Sinister came to kill him, Yuri had no way to protect himself, and he was quickly murdered.

Like Colossus, Yuri is a descendant of sorcerer and mutant Grigory Efimovich Rasputin, who worked with Mister Sinister as part of a mutant breeding program in the late 1800s. After his death, Grigory was able to disperse his consciousness into his bloodline, with a sliver of his persona hidden in the minds of each of his descendants. Mister Sinister set out to kill off the sprawling Rasputin family tree in order to focus Grigory into a single body and bring back his old ally. Thankfully, Colossus was able to stop him.

12 Elena

Colossus' Great-Grandmother Was an Early Mutant

Also introduced in X-Men: Colossus - Bloodline, Elena is Colossus' great-grandmother - a telekinetic mutant who was the first member of a dark cult surrounding Grigory Efimovich Rasputin. Elena and her brother Ivan were caught up in Rasputin and Sinister's plans, though for a time Elena was a true believer in Rasputin's claims of divinity. After her brother Ivan arranged to have Rasputin assassinated, Elena faked his murder, unable to actually slay her brother. The two reconnected later in life, and Elena's example later influenced Colossus' victory over Sinister.

11 Sprite, aka Charles Rasputin

Colossus' Son from the Iconic 'Days of Future Past'

X-Men's iconic 'Days of Future Past' storyline depicts a world where the X-Men's dream has failed - mutants are rounded up into concentration camps, with Sentinels patrolling the planet to hunt down homo superior. In 2023, Marvel gave the legendary story a prequel in Marc Guggenheim and Manuel Garcia's X-Men: Days of Future Past - Doomsday. The story follows the fall of the X-Men and the rise of anti-mutant sentiment, with Sentinels wiping out many beloved mutant heroes.

Tragically, one such casualty is Sprite - Colossus and Shadowcat's future son. Named for Professor X, Charles inherited his mother's phasing powers, but he sadly perished while trying to use them to take down a Sentinel. Even in the wake of their young son's murder, Colossus and Shadowcat fought on to forge a future for mutantkind.

10 Goliath, aka Jean Rasputin

Colossus' Daughter with Kitty Pryde and Sprite's Sister

Also debuting (and dying) in X-Men: Days of Future Past - Doomsday, Piotr and Kitty's daughter Jean is named for their former teammate Jean Grey. She inherited her father's metal skin and enhanced strength, but tragically was likewise slain by the Sentinels while heroically fighting for freedom.

9 Kid Colossus, aka Peter, Son of Nereel

Colossus' Long-Lost Son Is One of His Biggest Tragedies

This entry technically covers two characters - Peter (Son of Nereel) and Kid Colossus. Introduced in X-Men Annual #12 (by Chris Claremont and Arthur Adams), Peter is the son of Nereel - a resident of Marvel's dinosaur-infested Savage Land. While Peter's father is Colossus, the X-Men hero has yet to learn that he has a son, despite playing with the child when visiting his former lover. Peter is a forgotten time bomb waiting to go off in Marvel's main continuity, with fans eagerly waiting for the day Colossus learns he's a father.

However, in the alternate timeline of Chris Claremont and Sean Chen's X-Men: The End, fans got to see Peter not just grow up, but even the X-Men as Kid Colossus. The story charts the future of the X-Men franchise, with the mutant heroes going up against Mister Sinister, Stryfe, the Skrulls, and other iconic villains. This version of Peter has the same powers as his father, and is even the father of our next entry...

8 Pavel Rasputin

Colossus' Grandson Was Part of X-Men's GeNext Team

Introduced in Chris Claremont and Patrick Scherberger's GeNext #1, Pavel is the son of Kid Colossus, and thus the grandson of the original Colossus. This alternate timeline follows on from X-Men: The End, depicting a whole new class of mutant students who make their way in the world. A reckless fighter, Pavel has the same superstrength, durability and metal skin as his grandfather. Pavel has faced off against a number of villains including the Neo - an extremist sect of mutants who have sworn vengeance against the X-Men.

7 Unnamed Son

Colossus' Mysterious Son Has a Grudge Against Wolverine

So new to Marvel lore that fans don't even know his name yet, the recent Wolverine: Revenge #4 (from Jonathan Hickman and Greg Capullo) introduced Colossus' mysterious son. This series is set in an alternate reality where a massive technological disaster led to the fall of America. Colossus ed the Brotherhood of Mutants in order to secure a rare energy source that would keep Russia safe, and was therefore linked to a plan that claimed the lives of heroes including Steve Rogers' Captain America and Bucky Barnes' Winter Soldier.

Following this disastrous attack, Wolverine made it his mission to kill every member of the Brotherhood, murdering his old friend in the process. However, Colossus left family behind, and the 'Revenge' of the title has now flipped, with a badly injured Sabretooth recruiting Colossus' son to take down Wolverine. While little is known about this character so far, he appears to have his father's unbreakable skin and the Rasputin family Soulsword, on which more shortly...

6 Christina Pryde

Colossus' Daughter with Kate 'Kitty' Pryde Comes from X-Men's Darkest Timeline

2015 saw the release of Marguerite Bennett and Mike Norton's Years of Future Past, exploring a new alternate reality based on the iconic 'Days of Future Past.' Here, Colossus and longtime love interest Kate Pryde are still alive and fighting as part of the resistance, and fans get to see their kids in action. Christina 'Chrissie' Pryde has an advanced version of her father's powers. Rather than just converting her body to a steel-like substance, Chrissie becomes a liquid metal, allowing her to shapeshift and stretch into different forms. Chrissie mostly uses this to form blades and shields, while also gaining enhanced durability more her malleable form.

5 Cameron

Colossus' Son, Raised by Wolverine, Is Also Christina's Brother

Despite being Christina's brother, Cameron was raised very differently. With his parents imprisoned in a concentration camp, Cameron was saved and raised by Wolverine. The two returned years later to free Colossus and Kitty, with Cameron revealing he has a wild evolution of his mother's phasing powers. Cameron can merge with any substance he touches, moving through it at alarming speeds. Cameron merges with his targets on the molecular level, allowing him to travel vast distances by - for instance - merging with one end of a road and emerging at the other side.

However, as expected from anyone raised by Wolverine, Cameron's powers also have major offensive potential. This was shown when Cameron merged with a reanimated Blob, bursting free from the villain's stomach and killing him instantly. Cameron attempted to assassinate human supremacist Baron Robert Kelly, only to be killed by Chrissie, who believed that the X-Men protecting their oppressors against 'evil mutants' was the only way to change humanity's hatred of homo superior.

4 Mikhail Rasputin

Colossus' Older Brother Is a Conflicted Villain

Colossus' older brother, Mikhail Rasputin is a former cosmonaut assumed dead after disappearing into a dimensional rift. Mikhail has the ability to manipulate space on the subatomic level - this allows him to open 'rifts' through which he can access other dimensions, which he uses for both teleportation and powerful energy blasts. Immensely strong, Mikhail has worked both with and against Colossus over the years, disdaining the dream of mutant/human coexistence while still loving his brother.

Sadly, in the recent X-Force #46 from Benjamin Percy and Robert Gill, Colossus killed Mikhail after his brother oversaw a plot to mind-control him into betraying the X-Men, which included Colossus being forced to kill his girlfriend Kayla.
