Juggernaut (character)
Juggernaut, the Marvel Comics villain whose real name is Cain Marko, made his debut in X-Men #12, dated July 1965, without ever showing his face. For most of that issue he was an unseen force tearing through the X-Men's headquarters. Meanwhile, Professor X told the villain's origin to his students in a series of flashbacks. Only in the final panel did Marko step into view and confront Xavier. Writer Stan Lee and artist Jack Kirby, who also co-wrote, had built a menace around one terrifying idea: something that simply keeps coming. Over the following decades, Marko would clash with Spider-Man, the Hulk, and the X-Men again and again. Several questions follow him. How does an ordinary man come to shatter mountains? What ties him to the leader of the X-Men? And what happens to a villain built never to stop when the world around him keeps changing?
The name comes from Jagannath, a Hindu deity honored with a towering chariot about sixty feet high. Roughly two hundred people pull it. It rolls with such force and devotion that it keeps moving even if someone falls in its path. That image is the character in miniature.
Cain Marko's strength is enough to shatter mountains. He can lift buildings and swing them as weapons. At full power he also generates a mystical force field that adds protection against any physical blow. He never tires from exertion, and he can survive without food, water, or oxygen. His body repairs itself quickly. When the character Shatterstar stabbed him through the eyes, the wounds closed almost at once. Once he is in motion, he is described as physically unstoppable.
The helmet is the one piece of his armor that matters most. It shields him from mental attacks, so any foe who removes it can reach his mind. He has sometimes guarded against that by wearing a metal skullcap underneath. While he holds the full power of the gem that fuels him, he can magically rebuild a lost helmet from raw materials nearby.
Momentum is the other weakness. An opponent with enough physical or mystical strength can redirect his charge until he ends up stranded somewhere he cannot escape. In a contest of pure strength, only one character has ever stopped him in mid-motion. That was the Hulk, during the time he served as War, a horseman of Apocalypse empowered with Celestial technology. None of this power was Marko's by birth, and the story of where it came from begins inside a stepfamily.
Kurt Marko married Sharon Xavier after the death of her husband Brian, a death for which Kurt was partly responsible. The marriage made Cain the stepbrother of Charles Xavier. Kurt favored Charles and abused his own son. Cain resented Charles and bullied him often.
In Korea, both stepbrothers served in the US Army. Cain found a hidden temple dedicated to an entity named Cyttorak. Inside, he lifted a huge ruby and read its inscription aloud. It said: "Whosoever touches this gem shall be granted the power of the Crimson Bands of Cyttorak! Henceforth, you who read these words, shall become... forevermore... a human juggernaut!" The gem poured Cyttorak's power into him. The transformation caused a cave-in, and Marko was buried and presumed dead.
Cyttorak's gift carried a price that took decades of stories to reveal. One storyline showed that Marko is only the latest in a series of incarnations of Cyttorak's avatar. Each incarnation battles a challenger to the death for the right to keep the entity's power.
The god also had more than one jewel. In X-Men #32-33, from 1967, Cyclops and Marvel Girl used a second jewel, with help from the astral form of Doctor Strange. It banished Juggernaut to the Crimson Cosmos, Cyttorak's home dimension. He returned with mystical abilities, fought Doctor Strange, and was then sent to an alternate universe by the cosmic entity Eternity.
In the 1990s, the Onslaught storyline delivered a harsher lesson. Onslaught defeated Juggernaut, imprisoned him in the Gem of Cyttorak, and humiliated him there. He escaped.
Juggernaut: The Eighth Day #1, published in November 1999, introduced the Exemplars. Juggernaut and seven other humans had all been empowered and corrupted by mystical entities, and they served as avatars enforcing those beings' wishes on Earth. Juggernaut resisted Cyttorak's influence. When the other Exemplars captured him, the Avengers came to his aid. Captain America convinced the Exemplars that they had been manipulated, and the entities chose to leave Earth.
During the Trion saga, Marko gained complete access to the gem's power, which multiplied his power a thousandfold. This Trion form could change the size of matter, grow larger, levitate, and absorb and project energy. It could also open portals through space-time.
Later, the Crimson Gem reappeared in the ancient temple and sent out a call for a new Juggernaut. Marko, finally at peace, sensed it. He and Colossus fought, then realized they shared a goal. Both wanted to destroy the gem so that no new avatar could be empowered. Ahmet Abdol, the former Living Monolith, claimed it first. Colossus invoked Cyttorak and argued that Abdol would fail the god, as every earlier avatar had. He dared the god to try something new and empower him enough to kill Cyttorak himself. The god, apparently daunted, withdrew his power from Abdol and returned it to Marko.
The gem did not last. In a fight against the Office of National Emergency, General Callahan forced Magik to transform into her Darkchylde form. That form destroyed the Gem of Cyttorak and banished Juggernaut to Limbo.
In his 2020 solo series, by Fabian Nicieza and Ron Garney, a depowered Cain wanders Limbo until he escapes by destroying his armor. Back on Earth, he travels the world for answers and finds the Forge of Cyttorak in North Korea. There he takes the Crimson Bands of Cyttorak, which bond to him, restore his powers, and give him armor he can summon at will. Cyttorak confronts him at once. Cain replies that the armor is made from the Bands, so the god no longer has a hold on him. He vows never again to work for gods or madmen.
In X-Men #12 and #13, Professor X met his stepbrother's first attack with help from outside the team. He summoned the Human Torch of the Fantastic Four. The Torch generated pulses of flame that nearly hypnotized Juggernaut and bought time. Angel then pulled off the helmet, which left Marko open to a telepathic strike from Xavier.
In the 1970s, an interdimensional device built to banish the Hulk pulled Juggernaut back to Earth by accident at the Hulkbuster base. The Hulk helped him escape the base but attacked him when Juggernaut threatened a civilian. During the fight, Juggernaut's helmet came off. Professor X, Cyclops, and Marvel Girl then surprised and defeated him.
The stepbrothers met face to face in X-Men: Legacy #219, in February 2009. Charles Xavier, leader of the X-Men, stood against the man who had bullied him as a boy.
During the World Hulk storyline, Juggernaut's power began to fade. He restored the link to Cyttorak by shunning Xavier and returning to his villainous nature. That made him strong enough to hold his own against the Hulk. Xavier tried to reform him anyway, and in the end he conceded that redemption was impossible.
Xavier later changed his mind. When Luke Cage became leader of the Thunderbolts and considered recruiting Juggernaut, Xavier contacted Cage telepathically. He asked Cage to reconsider, believing Marko still had a chance at redemption.
In the 2020s, a telepathic projection of Xavier visited Cain in a hospital to check on his condition. While Cain had been lost in Limbo, mutantkind had rebranded itself as a sovereign nation called Krakoa. Xavier sadly told him that Krakoa had refused him citizenship because he is human. That changed after the Quiet Council of Krakoa voted to grant citizenship to human relatives of mutants.
Black Tom Cassidy, cousin of the X-Man Banshee, befriended Juggernaut and fought beside him against the first generation of new X-Men. When Tom fell from the battlements of Cassidy Keep after a sword duel with Banshee, Juggernaut jumped into the sea after him.
In the Spider-Woman issues of 1981, Tom used his niece Siryn, who has the same powers as her father Banshee, to steal a shipment of the metal vibranium. Juggernaut fought Spider-Woman and the X-Men. He was the only member of the criminal trio to escape capture.
Tom freed him from prison, then decided that the psychic Madame Web could be useful to his schemes. In New York City, he sent Juggernaut to seize her. Juggernaut flattened several city blocks and ignored Spider-Man's best efforts to stop him. He nearly killed Web by accident when he pulled her off a life support device, and then he abandoned her.
Spider-Man found his answer in concrete. He lured Juggernaut into the setting concrete poured for the foundation of an office high-rise. Juggernaut sank without a trace, and it took him over a month to dig his way out.
In civilian clothes, Juggernaut once got into a bar fight with Colossus, who did not know who he was. The same disguise later helped him trick and capture the Hulk, who was then allied with the Red Skull.
Not every fight went his way. The futuristic Sentinel Nimrod defeated and humiliated him. That Sentinel would return much later, at a far bloodier moment.
In The Uncanny X-Men #410-413, published from September to December 2002, a ruse by Black Tom Cassidy placed Juggernaut inside the X-Men. The plan was to destroy the team from within. When Cassidy openly betrayed him, Marko tried to change his ways and truly joined.
A young mutant named Sammy Paré helped Marko reform, despite setbacks such as a battle with the Canadian team Alpha Flight. Sammy then discovered that Exodus's Brotherhood of Mutants was preparing to strike the X-Men's headquarters. The Brotherhood did not know that Juggernaut was a mole in their ranks. Black Tom Cassidy killed Sammy. Enraged, Juggernaut attacked Cassidy and his allies, and the battle stranded everyone in the Mojoverse.
During The Gauntlet storyline, Spider-Man found Juggernaut unconscious, and the government moved him to a secure facility. A new Captain Universe, a man named William Nguyen, broke in to take revenge for the ruin of his life in an earlier fight. The Uni-Power left Nguyen and entered Juggernaut. As Captain Universe, Juggernaut repaired the damage to the tectonic plates beneath New York City that his own rampage had caused.
Weakened after losing the Uni-Power, Juggernaut sat in the Raft prison when Luke Cage became leader of the Thunderbolts. He agreed to do whatever Cage said, partly because nanomachines now coursed through his body. He served on the team from issue #144 to issue #158.
During Fear Itself, one of the seven Hammers of the Worthy landed near him. When he lifted it, he became Kuurth: Breaker of Stone. The transformation was enough to level the Raft and cause a mass prison break. Wolverine, wearing Uru armor, eventually defeated Kuurth.
Juggernaut later joined Magneto's latest Brotherhood of Mutants and attacked an Air Force base with them. In a fight with the X-Men, Magneto turned out to be his clone Joseph in disguise. Furious at the treachery, Juggernaut restrained Joseph and rejoined the X-Men.
Joining Damage Control brought a new problem. Juggernaut faced mounting legal issues over the damage caused by his public activities. Once Krakoa admitted him, he was appointed to work with Nightcrawler's Legionnaires. After months of service, Marvel Girl nominated him for the newest X-Men lineup. He was elected, to his surprise and joy, and debuted at the third Hellfire Gala.
The celebration ended in disaster. Orchis forces attacked the Gala, and many mutants were killed. Nimrod killed most of the new X-Men and beat Juggernaut unconscious.
During Fall of X, Orchis imprisoned Juggernaut at the Henry Gyrich Re-education Center alongside Cyclops. A bomb was rigged to Cyclops to explode if Juggernaut tried to break free. Kitty Pryde sneaked in and disabled it, but Nimrod spotted her and she had to flee. Then Doctor Stasis tried to transfer Juggernaut's powers to himself. Firestar, a double agent for the X-Men inside Orchis, helped Juggernaut escape without blowing her cover.
Juggernaut rejoined the X-Men after Orchis spread propaganda that turned the public against mutants and their sympathizers. The team went underground. Juggernaut rescued Krakoa, the living island, which had shriveled into a small avatar without mutant energy. Then he fought Orchis's forces, whose Adamantium weaponry nearly overwhelmed him until Apocalypse and Sunfire backed him up.
In 1994, Marvel bought Malibu Comics and began crossovers that sent Marvel characters into Malibu's Ultraverse. In 1995-96, Juggernaut led a group of Ultras called the All New Exiles. They met the X-Men in a special collaboration, The All New Exiles vs X-Men #0, dated October 1995.
In the Age of Apocalypse, an alternate Cain Marko is a monk who protects Avalon, a secret refuge for mutants. In Marvel Apes, a primate version named Juggermonk joins the Ape-Vengers.
In Marvel Zombies, a zombified Juggernaut dies when Wolverine shoves a fist into his mouth. Wolverine then uses his newly obtained cosmic powers to decapitate him.
In the MC2 line, the series J2 stars Zane Yama, the son of Juggernaut. He inherits his father's powers, goes by the name J2, and joins the future Avengers. Later he reunites with Cain Marko, who is trapped in an alternate dimension.
The Ultimate Marvel version is a childhood friend of Rogue. Weapon X imprisoned him and forced him to act as a living weapon under John Wraith. He bonded with the Gem of Cyttorak after meeting Gambit and Rogue, who had stolen it from Fenris. During the Ultimatum storyline, he helped Rogue defend the X-Mansion from anti-mutant soldiers led by William Stryker. A poisonous dart hit him in the eye, and he died in Rogue's arms.
Two What If stories ask about different turning points. In one, Charles Xavier finds the Crimson Gem instead of Cain Marko. Marko then joins Magneto and Xavier's disillusioned students to send Xavier into space. In What If? volume 2 #94, Juggernaut wins his first battle against the X-Men. Without the team to oppose them, the Sentinels are released in huge numbers and devastate Earth. Juggernaut eventually destroys the Sentinels but is left alone in a post-apocalyptic wasteland, because radiation from the Sentinels has killed most other life.
In Worst X-Man Ever, Juggernaut tries to steal a fortune and ends up fighting the New Mutants. Minerva stops him by creating a well beneath his feet that sends him to the bottom of the Earth.
Vinnie Jones played Juggernaut in X-Men: The Last Stand, released in 2006. This version is a mutant who cannot be halted once he starts running, with no explicit link to Charles Xavier or the Gem of Cyttorak. He is recruited into Magneto's Brotherhood to oppose and destroy a mutant cure, and Kitty Pryde and Leech thwart him. Jones later said he would like to return in a spin-off, because the film gave him too little time to add depth. The character was nearly in the first X-Men film as well. Andrew Kevin Walker's first script for X-Men, released in 2000, placed him in Magneto's Brotherhood.
Josh Helman was originally going to play Juggernaut in X-Men: Days of Future Past. The character was replaced by Quicksilver, and Helman was recast as William Stryker.
In Deadpool 2, released in 2018, Juggernaut is a computer-generated character built with motion capture. Ryan Reynolds supplied the voice and the body movement, while director David Leitch performed the facial capture. Juggernaut begins the film imprisoned at the Ice Box, an isolated prison for mutants, where he befriends Rusty Collins. Collins frees him during a prisoner transfer. They destroy the convoy, then set out to destroy the orphanage where Collins was abused. Deadpool, Cable, and Domino intercept them, and Juggernaut holds them off until Colossus, Negasonic Teenage Warhead, and Yukio overpower him.
Deadpool & Wolverine, released in 2024, features an alternate timeline variant based on the Last Stand version, played by Aaron W. Reed. Vinnie Jones was considered for the return and declined.
Screen versions disagree about where his strength comes from. In the films most notably, Marko is a mutant born with his powers. In other adaptations, the powers simply come from his costume.
On television, William H. Marshall voiced him in the Spider-Man and His Amazing Friends episode 'A Firestar is Born,' with stock grunts from Bob Holt. Rick Bennett voiced him in X-Men: The Animated Series, and Tom Kenny in The Super Hero Squad Show. In video games, he is a boss in the 1992 X-Men game and a playable character in X-Men vs. Street Fighter and Marvel vs. Capcom 2: New Age of Heroes. Fred Tatasciore voiced him in several games, and John DiMaggio in X-Men Legends. The rapper Open Mike Eagle wrote the song 'Legendary Iron Hood,' on the album Brick Body Kids Still Daydream, from Juggernaut's perspective.
Rankings have followed him too. In 2008, Wizard ranked him 188th on its list of the Top 200 Comic Book Characters. In 2009, IGN placed him 19th among its Top 100 Comic Book Villains and ranked him Spider-Man's 22nd greatest enemy. Entertainment Weekly ranked him 81st in a 2014 list of every X-Man, and in 2018 CBR.com placed Cain Marko 4th among the strongest characters of the Age of Apocalypse.
On the 14th of February 2006, the parody troupe My Way Entertainment released an overdub of 'The Cry of the Banshee,' an episode of X-Men: The Animated Series. The ad-libbed dialogue mixes slang, profanity, and non sequiturs. One line, in which Juggernaut demands to know whether you know who he is, was repeated endlessly. At first the clip lived on the duo's college website, but it spread widely once YouTube became popular. The line was popular enough to be included in The Last Stand, during Juggernaut's fight with Kitty Pryde. My Way released a sequel in June 2006, using footage from the episode 'Juggernaut Returns.' A second sequel followed on the 10th of June 2007, using footage from 'The Unstoppable Juggernaut' and Pryde of the X-Men. Even the video game Call of Duty: Modern Warfare 2 nods to the parody, with an achievement named 'I'm the Juggernaut...'.
