The character debuted as an antagonist of the titular mutant superhero team in X-Men #12–13 (July & September 1965). In the first of these issues, he rampaged unseen throughout the X-Men's headquarters while the team's leader, Professor X, related the character's origin in a series of flashbacks.
After an initial defeat the following issue, the Juggernaut returned in X-Men #32–33 (May–June 1967), then fought the sorcerer Doctor Strange in Doctor Strange #182 (September 1969), X-Men member the Beast in Amazing Adventures #16 (January 1973), and the Hulk in The Incredible 'Hulk #172 (February 1974).
After the canceled X-Men returned in the mid-1970s, the Juggernaut returned to fight a new iteration of the team in X-Men #101–103 (October 1975–February 1976). Storylines in Spider-Woman #37–38 (April & June 1981) and The Amazing Spider-Man #229–230 (June–July 1982) explored the Juggernaut's relationship with ally Black Tom Cassidy.
The X-Men and Spider-Man proved to be regular foes for the character, who appeared in Uncanny X-Men #183 (July 1984), Marvel Team-up #150 (February 1985), and Uncanny X-Men #194 (June 1985). The Juggernaut guest-starred in Secret Wars II #7 (January 1986), battled a new generation of mutants in X-Men #217–218 (April & June 1987), appeared in a flashback story in Marvel Saga #21 (August 1987), and in a humorous episode in Excalibur #3 (December 1988).
The Juggernaut also participated in the "Acts of Vengeance" storyline in Thor #411–412 (December 1989) and returned in Thor #429 (February 1991). Other appearances included an encounter with his creator, Cyttorak, in X-Men Unlimited #12 (September 1996) and starring in the one-shot issue Juggernaut #1 (April 1997).
In 1994, Marvel purchased Malibu Comics, and began a series of crossovers that saw Marvel characters entering the Malibu Ultraverse. In 1995-1996, Juggernaut lead a group of Ultras which were named The All New Exiles. The All New Exiles eventually met up with the X-Men in a special Malibu/Marvel collaboration, The All New Exiles vs X-Men, Issue #0, dated October 1995.
The character appeared in Juggernaut: The Eighth Day #1 (November 1999) and Avengers Vol. 3, Nos. 23–25 (December 1999–February 2000) with similarly powered avatars and attempted a reformation in Uncanny X-Men # 410–413 (September–December 2002) and X-Men #162–164 (November 2004–January 2005). The Juggernaut confronted his stepbrother, Charles Xavier—leader of the X-Men—in X-Men: Legacy #219 (February 2009), and fought the Hulk in Hulk #602 (November 2009).
He appeared as a regular character in Thunderbolts beginning with issue #144, and remained on the team until issue #158 during the Fear Itself limited series.
Fictional character biography
Cain Marko is the son of Kurt Marko, who became Charles Xavier's stepfather when he married Sharon Xavier after the death of her husband Brian, for which Kurt was partially responsible. Kurt Marko starts to favor Charles, and abuses his own son, Cain. Cain begins to resent Charles and bullies him frequently. When Cain Marko and his step-brother Charles serve in the US Army and are stationed in Korea, Marko finds a hidden temple dedicated to the entity Cyttorak. Upon entering Marko finds and holds a huge ruby, and reads the inscription on the stone aloud: "Whosoever touches this gem shall be granted the power of the Crimson Gem of Cyttorak! Henceforth, you who read these words, shall become ... forevermore ... a human juggernaut!" The gem channels Cyttorak's power into Marko. The transformation causes a cave-in, with the character buried and presumably killed, not being heard from again until a sudden assault on the X-Men's headquarters.
Xavier recounts the Juggernaut's origin to the X-Men, and after shrugging off the mansion's defenses and brushing aside the X-Men, Marko is clearly seen in the final panel as he confronts Xavier. The X-Men regroup and attack, while Xavier summons Fantastic Four member the Human Torch to aid the mutants, the Torch generating 'pulses' of flame that essentially hypnotize the Juggernaut, distracting him long enough for the Angel to remove his helmet, making Marko susceptible to a telepathic attack by Xavier.
The Juggernaut returns seeking revenge, and is delayed by three of the X-Men while Cyclops and Marvel Girl - aided by the astral form of mystic Doctor Strange - find and use another jewel of Cyttorak, which banishes the Juggernaut to the "Crimson Cosmos", the home dimension of Cyttorak. When the Juggernaut reappears the character has gained mystical abilities and briefly battles the mystic Doctor Strange before being banished to an alternate universe by the cosmic entity Eternity.
Juggernaut reappeared on Earth through sheer force of will, although the alien dimension caused him to age rapidly. The panicking villain battled former X-Man the Beast before being drawn back to the same dimension. An entity from his prison dimension reversed the aging process and removed the mystical powers on the proviso that the villain never return. The Juggernaut was accidentally pulled back to Earth at the Hulkbuster base by an interdimensional device designed to banish the Hulk. The Hulk aided the Juggernaut in escaping from the base, but attacked when the Juggernaut threatened a civilian. During the battle his helmet was removed, and he was surprised and defeated by Professor X, Cyclops, and Marvel Girl.
The Juggernaut befriended Black Tom Cassidy, the cousin of X-Man Banshee, and battled the first generation of new X-Men. When Tom fell off the battlements of Cassidy Keep after a sword duel with Banshee, Juggernaut jumped after him into the sea.
Black Tom used his niece Siryn - who possesses the same powers as her father Banshee - to steal a shipment of the metal vibranium. The Juggernaut battled Spider-Woman and the X-Men, and was the only one of the criminal trio to escape capture. After freeing him from prison, Black Tom decided the psychic Madame Web could be useful in his criminal pursuits. On arriving in New York City, Tom sent the Juggernaut to capture Madame Web, with the villain destroying several city blocks and ignoring Spider-Man's best efforts to stop him. The Juggernaut almost killed Web by accident when he removed her from a life support device, and decided to abandon her. A frustrated Spider-Man eventually lured the Juggernaut into setting concrete, poured for the foundation of an office high-rise, into which he sank without a trace; he took over a month to dig his way out.
The Juggernaut, in civilian guise, had a bar fight with the X-Man Colossus, who was at first unaware of the villain's true identity. After another battle against Spider-Man and the X-Men, the Juggernaut encountered the futuristic Sentinel Nimrod, who humiliated and defeated him. The Juggernaut was one of the villains assembled to battle the cosmic entity the Beyonder. The Juggernaut battled an all-new generation of X-Men, appears in a flashback story with the original X-Men, and had a humorous encounter with Captain Britain.
The Juggernaut continues to feature prominently in Marvel titles, starring in an alternate universe adventure, battling Thor once again  and starring opposite other characters such as the mutant team X-Force, Doctor Strange, the Hulk (allied at the time with master villain the Red Skull and tricking and capturing the Hulk with the same "civilian" guise used against Colossus), mercenary Deadpool, the villain turned antihero Venom, and multiple battles with the X-Men. The Juggernaut suffers a major setback during the Onslaught storyline, being defeated and then humiliated by the entity when imprisoned in the Gem of Cyttorak. The Juggernaut, however, eventually manages to escape.
The Juggernaut also stars in a solo story and the "Eighth Day" storyline, which introduces the entities the Exemplars. The Juggernaut and seven other humans are revealed to have all been empowered and corrupted by mystical entities, and as avatars enforce their will on Earth. The Juggernaut resists the influence of Cyttorak and when captured by other Exemplars is aided by the superhero team the Avengers. Leader Captain America convinces the other Exemplars that they have been manipulated by the mystical entities, who then decide to leave Earth.
The Juggernaut, courtesy of a ruse engineered by Black Tom Cassidy, eventually allies with and joins the X-Men, the plan being to destroy the team from within. When Cassidy openly betrays the Juggernaut, Marko decides to remain with the X-Men and attempt to change his ways. The Juggernaut befriends a young mutant boy called Sammy Paré, who helps Marko reform, despite setbacks such as a battle with the Canadian superhero team Alpha Flight. When Paré, however, discovers that Black Tom Cassidy is preparing to attack the X-Men's headquarters, he is killed. An enraged Juggernaut attacks Cassidy and his allies, with the battle stranding all participants in the alternate dimension the Mojoverse.
The Juggernaut reappears and joins the team New Excalibur for a brief period. One storyline expands on the Juggernaut's origin, and reveals that Marko is only the most recent of a series of incarnations of Cyttorak's avatar, with each battling a challenger to the death for the right to retain the entity's power. During the World War Hulk storyline, the Juggernaut's power begins to wane, but by shunning his stepbrother Xavier and returning to his villainous nature is able to restore the link with Cyttorak, becoming powerful enough to hold his own against the Hulk. Despite an attempt by Xavier to reform Marko, he concedes that redemption is impossible.
While training his son Skaar, Bruce Banner bombs Juggernaut's house to initiate a confrontation between Skaar and the Juggernaut. Skaar manages to win his first fight by throwing the Juggernaut into open space, proving to his father that he has the ability to use cunning and strategy in combat, and not simply physical strength.
During The Gauntlet storyline, Spider-Man finds the Juggernaut unconscious. The government comes along and transports the Juggernaut to a secure facility. Spider-Man sneaks into the facility to ask the Juggernaut who did this to him. Then, a new Captain Universe breaks into the room and claims he's there to slay the Juggernaut. Spider-Man learns that Captain Universe is a man named William Nguyen who wants revenge on Juggernaut for ruining his life during his previous fight with Spider-Man over Madame Web. When he insists on trying to kill Juggernaut instead of fixing the tectonic plates beneath New York City, the Uni-Power leaves Nguyen and enters the Juggernaut. The Juggernaut, as Captain Universe, repairs the damage to the tectonic plates that was caused by him during the same rampage that ruined Nguyen's life.
Following the Siege storyline, Juggernaut is shown at The Raft at the start of the Heroic Age storyline - weakened, since Cyttorak apparently took his temporary empowerment by the Uni-Power as an affront, and withheld part of his "blessing". Following Luke Cage's appointment as leader of the Thunderbolts, Cain is brought up for suggestion for the program. While Cage is initially against him joining, Professor X telepathically contacts Luke and asks him to reconsider, believing he has a chance at redemption despite what he previously told Cain. Juggernaut agrees to do whatever Luke says, partly because he is now suffused with nanomachines which can affect him in his weakened state.
During the Fear Itself storyline, one of the seven Hammers of the Worthy lands near Juggernaut. Juggernaut is able to lift it and becomes Kuurth, Breaker of Stone. His transformation was enough to level the Raft. Kuurth makes his way to California and fights the X-Men. Magik, Colossus and Shadowcat go to Cyttorak's dimension and inform it that the Serpent has control over Juggernaut. Magik strikes a deal with Cyttorak who chooses her to become the new host of the Juggernaut's powers, however the entity ends up transferring the Juggernaut's powers to Colossus instead. Colossus was able to turn the tide on Kuurth before Kuurth is teleported away by the Serpent. During the last battle between the Avengers and the Worthy, Kuurth was defeated by Wolverine using his Uru armor, and lost his hammer when the Serpent was killed by Thor.
Cain Marko, apparently having been incarcerated after the events of 'Fear Itself', having lost the power of both Kuurth and Cytorakk (but retaining his enormous physique) is released into military custody. Subsequently, he is taken to the borders of the country of Sharzhad just as the Thunderbolts return from their tumultuous tumble through time, and Satana aids Man-Thing in opening a gateway to the Crimson Cosmos (or possibly an alternate universe where Cain Marko had died while still the Juggernaut). Pushing his hand through, Marko is re-empowered, becoming the Juggernaut once more - just in time to thunder forth and smash through the otherwise unbreakable force field surrounding the country. This allowed the Thunderbolts to resolve an otherwise deadly threat to the planet - as had been orchestrated by the Ghost, who had sent the request for Marko's release back through time. He soon lost these borrowed powers again, and went to live in solitude in the desert, still, it seems, super-strong, although not mystically-empowered. Likewise, around this same time Magik purged the Juggernaut powers from Colossus with her Soulsword.
Powers and abilities
When Cain Marko found the Gem of the mystical entity Cyttorak, he was empowered with magical energies and transformed into an immortal avatar for the entity in question. As the Juggernaut, Marko possesses superhuman strength, being capable of shattering mountains, lifting and using buildings as weapons, and extreme durability.
His durability is amplified by a mystical force field that grants him additional invulnerability to any physical attack (at its maximum). Even when the force field was temporarily absorbed by Thor's hammer, the Juggernaut's natural durability still proved to be great enough to withstand blows from Thor. The Juggernaut is described as physically unstoppable once in motion, does not tire from physical activity and is able to survive without food, water, or oxygen. The Juggernaut heals quickly, as when he was stabbed through the eyes by Shatterstar, the wounds were healed almost immediately.[volume & issue needed]
It is possible for an opponent with sufficient physical or mystical strength of their own to turn the Juggernaut's unstoppable movement against him, by redirecting his motion so he gets stranded in a position in which he has no escape; both the Hulk and his son, Skaar, have managed this feat physically, and Thor has managed this feat mystically with Mjolnir. The only character to have stopped Juggernaut while he was in motion as an act of pure physical strength was the Hulk while he was War, a horseman of Apocalypse.
When he has gained complete access to the Gem's powers during the Trion saga, it increased his power a thousandfold. Trion Juggernaut was capable of altering the size of matter, growing in size, tracking, levitation, absorbing and projecting energy, increasing his own strength, and creating portals through space-time.
The character is vulnerable to mental attacks, a weakness that has been exploited via the removal of his helmet, which normally protects him from such. The Juggernaut has circumvented this weakness on occasion by wearing a metal skullcap inside his main helmet. If Juggernaut loses his helmet he can magically recreate it from available raw materials (as long as he possesses the full power of the gem).
Age of Apocalypse
In the Age of Apocalypse universe, Cain is a monk who works as a protector of Avalon. He guides Mystique and Nightcrawler to meet Destiny, but subsequently suffers an aneurysm when his desire not to hurt others conflicts with his lust for violence during an attack on Avalon.
In the Marvel Zombies universe, a zombified Juggernaut is seen in a horde of zombified villains. He is later killed by Wolverine when Wolverine shoves his fist in Juggernaut's mouth and then proceeds to use his newly obtained cosmic powers to decapitate him.
In the futuristic MC2 universe, the title J2 stars the son of the Juggernaut, Zane Yama. Yama, who inherited his father's powers and goes by the name J2, joins the future Avengers, and is eventually reunited with his father Cain Marko, who was trapped in an alternate dimension.
In a reality where Xavier acquired the Crimson Gem rather than Cain, Cain joined forces with Magneto and Xavier's disillusioned students, the X-Men. Believing that Xavier's more ruthless methods contradicted his alleged dream of peaceful co-existence and using a telepathy-blocking headband to prevent Xavier from realizing what he was up to, they were able to expel the Juggernaut into space. Cain leaves with Magneto after Xavier's Juggernaut is dispatched.
In a reality where Cain successfully defeated the X-Men in their first battle, the Sentinels were thus released in mass numbers without the X-Men to oppose them, resulting in Earth being destroyed in their subsequent nuclear assault. Although Cain eventually managed to destroy the Sentinels through sheer persistence, he was left in a post-apocalyptic wasteland with all other human beings having been killed by the radiation that had been released by the Sentinels' attacks.
The Ultimate Marvel imprint title Ultimate X-Men features an alternate universe version of the Juggernaut, who was originally part of the Weapon X program and has ties to Rogue, having grown up in the same trailer park. At some point in his life he was incarcerated by Weapon X and forced to act as a living weapon under the direction of Col. John Wraith. Juggernaut was part of the strike force that took out the X-Men, forcing them into Weapon X as well. Cain and Rogue shared a cell while both were forced to serve Weapon X. When The Brotherhood of Mutant Supremacy removed the security implants that were prohibiting the mutants from leaving their cells, Juggernaut fought for his freedom. After the entire ordeal, Cain was offered a place with both Xavier's X-Men and The Brotherhood. Cain chose The Brotherhood, but later left the team for parts unknown.  Cain was captured by SHIELD. However, en route to a prison designed to contain the Hulk, there was an accident and Cain broke free. Retrieving his helmet, he began to track down Rogue, who was a thief along with Gambit, stealing the Cyttorak Gem from the Fenris twins. He also revealed that he had a crush on Rogue. Juggernaut was bonded with the gem when Gambit shoved it into his helmet. During the Ultimatum storyline, Juggernaut helps Rogue in defending the X-Mansion from anti-mutant soldiers led by William Stryker. He is shot in the eye by a poisonous dart fired by one of the anti-mutant soldiers and dies in Rogue's arms.

In their initial meeting, Juggernaut becomes a serious hazard for Spider-Man's desperate last-minute efforts to complete a school science fair project. Despite his claims of being unstoppable, however, he is finally held up and his costume consumed by the Awesome Android, rendering him powerless and helpless against a knockout punch from Spider-Man.

During the battle on Alcatraz Island, Magneto orders him to destroy the cure, but is foiled by Kitty Pryde and knocks himself out when he attempts to run through a wall while in the presence of the power-negating Leech. Vinnie Jones has said he would like to reprise Juggernaut in a spin-off, as he felt there was too little time in X-Men: The Last Stand to imbue the character with depth.
- Although Cain Marko himself doesn't appear in the film, two characters directly related to him are briefly featured in X-Men: First Class. In the opening sequences of the film, Mystique appears impersonating Cain's stepmother Sharon.

After losing his helmet and being dropped through an Oscorp building, Juggernaut finally discovers the fragment on his person and uses its power to strengthen himself for a final battle with Spider-Man.

On February 14, 2006, the parody troupe My Way Entertainment released "The Juggernaut Bitch!!", an overdub of part of the X-Men animated TV series episode "Phoenix Saga Part 3: Cry of the Banshee". "The Juggernaut Bitch!!" uses a variety of slang, profanity, and non sequiturs through ad-libbing. The parody includes the often-repeated line, "Don't you know who the fuck I am? I’m the Juggernaut, bitch!" At first, the clip was made available on the duo's college website but when YouTube became popular so did the parody.
The clip became a popular Internet meme, so popular that the line was included in X-Men: The Last Stand during Juggernaut's fight with Kitty Pryde. In June 2006, My Way released a sequel "J2: Juggment Day," using footage from "Juggernaut Returns". On June 10, 2007, My Way released a second sequel entitled "J3: Shadow of the Colossi" on their website using footage from "The Unstoppable Juggernaut" and "Pryde of the X-Men". The video game Call of Duty: Modern Warfare 2 has an achievement called "I'm the Juggernaut..."
