- ―Juggernaut to Colossus
Juggernaut (born Cain Marko) is a mutant who has superhuman strength and durability. He was a member of the Brotherhood of Mutants.
Juggernaut was recruited into the Brotherhood by Magneto after being freed from imprisonment by US Forces. Multiple Man and Mystique were alongside him. Because of his immense strength, Juggernaut immediately became one of Magneto's trusted generals.
When Magneto attempted to recruit Jean at her family home, Wolverine and Storm were left outside to face Juggernaut, Callisto, Quill and Arclight. Soon, Wolverine and Juggernaut engaged in a fight, with the latter emerging victorious (the Extended Cut of the fight revealed Wolverine as the victor, with the help of Storm).
During the battle of Alcatraz, Juggernaut was sent to kill Leech - the source for the mutant "cure". Shadowcat, meanwhile, went to stop him. He knocked himself out by colliding with a wall in an attempt to kill Shadowcat and Leech - the latter negating his power of irresistible force.
It is been brought to say that Juggernaut survived Phoenix's destruction of Alcatraz Island, but unknown if left whether using the cure or not.
Juggernaut was a prisoner at The Ice Box prison, held in a secure section of the facility. In the aftermath of Cable's assault on the prison, Russell Collins befriended the Juggernaut by sharing food with him. Because of Cable's attack on the prison, all prisoners were scheduled for transport to another installation.
Deadpool organizes a team of mutants to fight Cable and save Russell, whom he calls X-Force. The team launches their assault on the prison truck transporting Russell by leaping from a plane and parachuting in, but all members other than Wilson and Domino die in the landing. During the battle, Russell frees the Juggernaut, who destroys the truck and escapes with Russell. Cable decides to team up with Deadpool and they plan to stop Russell from killing the orphanage's abusive headmaster, an act which sets Russell down his murderous path.
Wilson, Cable, and Domino arrive at the orphanage to stop Russell and the Juggernaut but face difficulty fighting the latter, who proves too powerful for them. Colossus arrives and distracts the Juggernaut long enough for Cable and Wilson to catch up with Russell. Colossus, Negasonic Teenage Warhead, and Yukio managed to defeat the Juggernaut. With Yukio using her chain to restrain him, Colossus shoving a power cable up his anus and then Negasonic using her power to knock him into the pool electrocuting him.
He survived as he can be seen climbing out of the bath before the credits.

“That is such a Juggernaut thing to say"
- ―Juggernaut and Deadpool
In the revised timeline, despite being a criminal, Juggernaut seems to have some sense of honor as he helped Firefist for freeing him and acted as a friend to him, if not a business partner.
- Irresistible Force Embodiment - Juggernaut, once he begins to advance in a certain direction, is virtually impossible to halt. Some obstacles can slow his pace, but cannot completely halt him.
- Superhuman Strength - Juggernaut possesses immense superhuman strength, making him one of the physically strongest mutants (along with Colossus and Apocalypse), capable of effortlessly overpowering Wolverine and throwing him around like a ragdoll.
- Superhuman Durability - Juggernaut's skin, muscles and bone are several times denser than the same tissues in the body of a normal human being, greatly contributing to his superhuman weight, and making him extremely hard to wound. And while Wolverine's adamantium claws do pierce him, Juggernaut doesn't seem to feel much pain.
- Superhuman Speed - Juggernaut, despite his immense size, has his strong leg muscles allow him to run and move at speeds beyond the natural physical limits of the finest human athlete.
- Superhuman Stamina - Juggernaut's body generates no fatigue toxins during physical activity, granting him limitless superhuman stamina in all physical activities. He is never seen resting or sitting down whilst among the brotherhood.
- Superhuman Strength - Juggernaut possesses immense superhuman strength, making him one of the physically strongest mutants (along with Colossus and Apocalypse), being strong enough to rip Deadpool in half with little effort. Later he was able to dominate Domino, Cable and Deadpool and held the advantage for most of his fight against Colossus. He was also able to lift and throw a very large school bus through the air.
- Superhuman Durability - Juggernaut's skin, muscles and bone are several times denser than the same tissues in the body of a normal human being, greatly contributing to his superhuman weight, and making him extremely hard to wound. Juggernaut received a multitude of high caliber bullets and came out completely unharmed. Nor was he visibly affected by Colossus's blows.
- Master Combatant - Juggernaut is an extremely skilled fighter. He was able to maintain the lead for most of his duel against Colossus. He was also able to step down to Cable, Deadpool and Domino, three very skilled fighters.
- Helmet - In the Revised Timeline, Juggernaut wears a helmet that protects him from telepathic assault. In the Original Timeline, his helmet was only used for protection, similar to a battering ram.
- Magneto - Leader
- Mystique - Teammate
- Pyro † - Teammate
- Sharon Xavier † - Step Mother
- Professor X † - Step Brother
- P. Xavier - Step Brother
- Mystique - Foster Sister
- Juggernaut's fate in the original timeline is unknown; it's possible that the Phoenix's destruction of Alcatraz killed him since he may have been still unconscious when Jean was destroying the facility.
- In the mainstream comics, the Juggernaut is not a mutant and gains his power from the mystical Cyttorak Ruby. He is only a mutant in the Ultimate universe.
- During his fight with Shadowcat, Marko shouts, "I'm the Juggernaut, bitch!", referencing an Internet meme.
- In an alternate scene, when Juggernaut finds Leech and Shadowcat, he says, "Here's Juggy.", making a reference to the film The Shining.
- A younger version of Juggernaut was originally set to appear in X-Men: Days of Future Past and was to be portrayed by Josh Helman but was written out of the film and replaced by Quicksilver. Josh Helman went on to play William Stryker instead.
- In the comics, Juggernaut is the step-brother of Professor X and his twin sister Cassandra Xavier. He is an American born in Berkeley, California.
- Despite not being portrayed as Charles Xavier's step-brother in The Last Stand, in X-Men: First Class Charles mentions having a step-father who in the comics is Kurt Marko, Juggernaut's father. Deadpool 2 confirms that the Juggernaut, at least in the newly revised timeline, is Xavier's step-brother. It is possible that in the new timeline Cain Marko was born human and conceived after the events of Days of Future Past, and became the comic-accurate Juggernaut seen in Deadpool 2 after retrieving Cyttorak's gem at an older age.
- It isn't explained how either version of the Juggernaut was initially captured and restrained prior being freed in The Last Stand and Deadpool 2. Though he may have been sedated.
- In the comics, Juggernaut is an American character but in The Last Stand, he is portrayed as British. However, in Deadpool 2, he is depicted with a Brooklyn accent implying he was born in New York.
