…ACCESSING…
PERSONAL NOTES OF CHARLES XAVIER
“Cain Marko has been many things in my life – my stepbrother, my tormentor, my enemy. But above all, he has been a constant reminder that power, unchecked and untempered, can consume a person entirely.
Our childhood was fraught with tension. Cain resented me, believing that our father favoured me over him. He was right, though not for the reasons he assumed. My mutation allowed me to excel, to anticipate, to understand things beyond the surface. But to Cain, it was simply another way in which I had an unfair advantage. His anger festered, and when he discovered the Crimson Gem of Cyttorak, it gave him the means to unleash that rage upon the world.
As Juggernaut, Cain became an unstoppable force, a living embodiment of destruction. He was not a mutant, yet his power rivalled that of the strongest among us. Time and again, he sought to break me, to prove his superiority through sheer force. And yet, despite his strength, he was never truly free. Cyttorak’s influence bound him, shaping his path in ways he never fully understood.
But Cain is not the same man he once was. He has walked the road of redemption, struggling to find a purpose beyond vengeance. He has fought alongside the X-Men, not as a mutant, but as an ally – because he understands, finally, that strength is not measured by destruction, but by the willingness to protect those who cannot protect themselves.
In recent times, Cain has stood as a vital defender of mutant kind, proving that his past does not define him. He fights not for personal gain, but because it is right. It is a far cry from the villain he once was, and though his journey is far from over, I am proud to see the man he is becoming.“

X-MEN
FIRST APPEARANCE: The Unstoppable Juggernaut
VOICED BY: Rick Bennett
Juggernaut’s hatred for Professor Charles Xavier runs deep, stemming from their childhood as stepbrothers. Cain resented Charles, believing their father favoured him, and that resentment only grew over time. When Cain discovered the Tablet of Cyttorak, he recited its inscription, granting him superhuman abilities and making him nearly impervious to physical attacks.
His first major appearance comes when demolishes the X-Mansion, indirectly framing Colossus for the destruction. He later robs a bank, leading to a confrontation with the X-Men. Though his strength makes him a formidable opponent, Rogue ultimately defeats him by absorbing his powers, leaving him temporarily amnesiac [The Unstoppable Juggernaut].
Juggernaut returns with Black Tom Cassidy kidnap Lilandra, hoping to profit from her capture. However, his arrogance proves to be his downfall when he faces Gladiator, a member of the Shi’ar Imperial Guard, who effortlessly hurls him into the ocean [Cry of the Banshee].
He temporarily loses his powers when a civilian unwittingly steals the Ruby of Cyttorak. Mortally wounded by falling debris, Juggernaut is forced to rely on Professor Xavier and the X-Men to restore his abilities. In a rare moment of gratitude, he chooses to walk away rather than fight, throwing the Ruby of Cyttorak into space to prevent anyone from stealing his power again [The Juggernaut Returns].

OTHER APPEARANCES: Deadpool 2; Marvel Studios’ Deadpool and Wolverine
PLAYED BY: Vinnie Jones (X-Men: The Last Stand); David Leitch (Deadpool 2); Aaron W. Reed (Marvel Studios’ Deadpool and Wolverine].
Juggernaut is depicted as a mutant rather than a mystical being empowered by Cyttorak. He is a member of Magneto’s Brotherhood of Mutants, recruited to help stop the Mutant Cure. His defining trait remains his unstoppable momentum – once he begins charging forward, nothing can physically stop him.
His most memorable moment comes during the battle at Alcatraz, where he chases Kitty Pryde through the facility, only to be tricked when she phases a mutant boy with power-nullifying abilities into his path, rendering him powerless [X-Men: The Last Stand].
After the timeline change, perhaps, he is introduced as a prisoner in the Ice Box, where he is freed by Firefist and quickly proves to be a nearly unstoppable force. He brutally fights Colossus, showcasing his immense strength and resilience. His battle with Deadpool’s team ends when Negasonic Teenage Warhead and Yukio electrocute him, sending him into a river – though he survives [Deadpool 2].
A variant of Juggernaut was seen inside the Void, serving Cassandra Nova [Marvel Studios’ Deadpool and Wolverine].

FIRST APPEARANCE: Survival of the Fittest
VOICED BY: Paul Dobson
Juggernaut is introduced as a dangerous prisoner, held in a high-security facility due to his uncontrollable strength. His hatred for Professor Charles Xavier, his half-brother, remains a defining trait, fuelling his relentless pursuit of revenge. Mystique orchestrates his escape, hoping to use him as a weapon against the X-Men, but Juggernaut has no interest in alliances – his only goal is to destroy Xavier.
His invulnerability makes him nearly impossible to stop. He effortlessly tears through obstacles, shrugs off attacks, and even derails a moving train with a single push. The only known weakness he has is psychic attacks, but his helmet prevents telepaths from accessing his mind. The X-Men must work together to remove his helmet, allowing Xavier to subdue him with a psychic assault.
