* HeelFaceTurn: Cain already had his Heel-Face Turn before the book, but he manages to stay on the path (even when barred from Krakoa for not being a mutant) and, in the end, wants to make a whole team out of former villains used by others (like Quicksand and Primus) who'd be known as [[SuperheroTeam the Unstoppables]].

''Juggernaut'' Vol 2 (1999) was a one-shot tie-in to the "Eight Day" event that ran through ''ComicBook/IronMan'', ''ComicBook/{{Thor}}'', and ''ComicBook/SpiderMan'' at thei in time. It was written by [[Creator/ManOfActionStudios Joe Casey]], with art by Terry Shoemaker. The crossover was about eight power mystical entities who entered into a wager to determine who was the most powerful. Each entity would create a totem and the first mortal to touch that totem would be embued with the entity's power -- and, of course, Cyttorak was one of the eight mystical entities and the Juggernaut his champion.

''Juggernaut'' Vol 3 (2020–2021) was a five-issue mini-series written by Fabian Nicieza, with art by Ron Garney. Cain Marko is done with being a bad guy. He's recovered from [[ComicBook/UncannyXMen2018 being depowered]] and, even though he can't go to [[ComicBook/DawnOfX Krakoa]], he knows he can do some good working for ComicBook/DamageControl. But when he meets a young girl who goes by D-Cel, he'll have to face his past and figure out what his future really holds. Nothing can stop the Juggernaut -- except himself.

* {{Crossover}}: Between ''ComicBook/IronMan'', ''ComicBook/{{Thor}}'', and ''ComicBook/SpiderMan''. Since the Juggernaut was one of the main characters, but did not have an on going series like the others, he got a one-shot instead. Which was the climax of the story.

Juggernaut (Cain Marko) is a fictional character appearing in American comic books published by Marvel Comics. Created by writer Creator/StanLee and artist/co-writer Creator/JackKirby, he first appeared in X-Men #12 (July 1965) as an adversary of the eponymous superhero team. Since then, he has come into conflict with other heroes, primarily Spider-Man and the Hulk.

Charles Xavier's older step-brother and antithesis, Cain Marko was abused by his father Kurt, leading him to torment his stepbrother viciously and developing a deep-seated grudge against him. When they were both in the army during the Korean War, they took refuge in a cave where Cain discovered a magical ruby placed there by an EldritchAbomination named Cyttorak that turned him into its avatar -- the Juggernaut. Unstoppable in every way but via psionics or advanced magic, the Juggernaut continued to be a thorn in Xavier's side for years, eventually getting trapped inside of the source of his own powers. Since he was let out, he fought briefly on the side of good, before embracing his true evil nature and returning to villainy. Despite being associated with the [[Characters/XMenBrotherhoodOfMutants Brotherhood of Mutants]] for ''years'' in adaptations, he was never officially a member until joining Exodus' Brotherhood alongside his longtime partner in crime Black Tom.

Was rated #19 in the UsefulNotes/TopOneHundredComicBookVillains list.

----
!! The Juggernaut provides examples of:

* AbhorrentAdmirer: He's a fan of ComicBook/{{Dazzler}} and has a big crush on her. So he usually goes easy on her if she's on an X-team he's fighting.
* AbusiveParents: Kurt Marko used to beat him up horribly.
* AchillesHeel:
** He has a weakness to psychic powers (only when his helmet is removed). Also, he has no way of getting around besides walking, so if you can teleport him or trick him through a portal, he's stuck wherever he ends up until he manages to physically walk himself back to where he wants to be. Also, his powers being magic based, powerful entities such as Thor can more or less neutralize them once they've figured out exactly how they operate, ComicBook/IllyanaRasputin has actually been able to permanently remove the Juggernaut power from her brother Peter and Cain Marko himself. The Juggernaut's invulnerability is also magnitudes weaker against magic, so that higher power magic attacks will harm him.
** As a ''human'' juggernaut, his soft tissues, particularly those related to his nervous system, are somewhat vulnerable even without employing magic or psionics. His eyes can be cut by mundane objects should they be sufficiently sharp (as Shatterstar proved) and though he cannot feel pain, strong enough concussive force to his head can render him unconcious. A [[AntiMatter macroscopic annihilation reaction]] or [[StarKilling gamma ray bust]] is of course well outside of the range of most X-Men BUT is an energy level The Hulk or Thor could [[GatheringSteam potentially]] put out and was by the New God Mantis in a DC Comics crossover...[[WatchWhereYoureGoing which also knocked out Mantis]]). Atmospheric vibrations, such as ultrasound can also [[BodyHorror pulverize Juggernaut's brain and leave his body immobile]] (which is how Nimrod dealt with him).
* AdamWesting: Lightly so, as the ''ComicBook/AvengersAcademy'' title revealed that he has become something of a meme in youth circles, much to his exasperation. Despite this, he agrees with a roll of his eyes to yell "Nothing can stop the Juggernaut!" when Reptil asks him to.
* TheAgeless: Due to the gem of Cyttorak, he does not age.
* AntiVillain: Very occasionally played as a type IV AntiHero. As of 2014, he looks to be staying this way. [[spoiler: Even after returning to being the Juggernaut, his goal is to avenge his brother's death, even if his methods are insane.]]
* AscendedMeme: In ''Film/XMenTheLastStand'': "Don't you know who I am? I'M THE JUGGERNAUT, BITCH!"
* AttackItsWeakPoint: His helmet is his main protection against psi, his primary weakness. This has led to plenty of fights with Juggernaut that consist mostly of everyone distracting Cain long enough for someone to get his helmet off.
* BadPowersBadPeople: Because his powers are granted to him by a malevolent extradimensional entity, they actually fluctuate depending on how evil he is at any given time.
* BadassBoast: "Nobody/Nothing stops the Juggernaut!"
* BecauseYouWereNiceToMe: During the ''Gauntlet'' storyline, he helped Spider-Man after the wall-crawler tried to help him when he was attacked by the latest Captain Universe.
* BigBrotherBully: To Charles in their youth.
* BigBrotherInstinct: Surprisingly enough, his first return after Charles's death has him wanting to find out who did it to get revenge, explaining that Charles is one of the few people who ever gave him a second chance.
* BoxedCrook: During the 90s he became one when he brokered a deal to become the CSA's duly appointed bounty hunter. Later he was drafted into an incarnation of the Thunderbolts led by Luke Cage (his powers were [[PowerCreepPowerSeep on the wane]] at the time).
* BreakoutVillain: He's one of the more popular X-villains, appearing in numerous games and spinoffs.
* BroughtDownToBadass: On occasions where he has been depowered he still tends to acquit himself well in fights, though the degree to which he is truly ever "depowered" is unclear (for instance, in a 2014 storyline he still retained enough SuperStrength to punch Man-Killer through a roof, despite supposedly being stripped of his Juggernaut powers at the time).
* TheBrute: Typically serves this role as this whenever he's on a team.
* TheBully: In his backstory, where he pretty much tormented his stepbrother incessantly. As time went on he was given a FreudianExcuse to at least ''somewhat'' explain his unrelenting {{Jerkass}}ery.\\
\\
This side of Cain was particularly explored in an ''X-Men Unlimited'' issue released around the time he was undergoing his first attempted HeelFaceTurn. While attempting to be a big brother figure to MoralityPet Sammy the Squid Boy, Juggs and Sammy cross paths with a group of human kids who [[BadPeopleAbuseAnimals torture animals for fun]]. While Sammy is shocked and appalled, Cain shrugs it off easily with "boys will be boys" sentiments and openly admitting [[BadPeopleAbuseAnimals he did the same as a child]]. In comes Jean Grey, who decides to educate the bullies ''and'' Cain via full Phoenix-powered MindRape, making them all experience [[http://i.imgur.com/HZgogEC.jpg every torture they'd inflicted on an animal from the animal's point of view]]. While this was treated at the time as a lesson that would stick with Cain for a very long time, later storylines would see him [[StatusQuoIsGod predictably revert to form]].
* ButForMeItWasTuesday: Basically applies to his role in the ''Gauntlet'' storyline, as he's attacked by the latest Captain Universe because he ruined the man's life during a past rampage without ever being aware of it; Cain remembers the fight in question as it was his first fight with Spider-Man, but he doesn't remember the man currently attacking him.
* CainAndAbel: With Professor X.
* CharacterDevelopment: There wasn't much fans liked about the Chuck Austen X-Men era, but one move that was positively received was the development Cain got at the time stemming from his HeelFaceTurn. While the StatusQuoIsGod ResetButton was inevitably pushed, Cain stayed on the hero side for a good few years.
* CollapsibleHelmet: His newest helmet in the 2020 series can collapse and reform at will.
* CoolHelmet: Like Magneto, Cain has a helmet that protects him from PsychicPowers. ''Very'' handy when your stepbrother is the world's strongest telepath.
* CutLexLuthorACheck: For all that Juggernaut often ends up Worfed, on paper, he's one of the heaviest non-RealityWarper hitters in the Marvelverse. And what does he use his incredible power for? Basically thuggery.
* {{Dismotivation}}: Juggernaut is one of the most powerful beings in the X-Men universe, as his powers aren't mutations so much as a law of physics unto themselves. Despite this, he's still Cain Marko, and his ambitions usually loft no higher than petty thievery, thuggery, and the occasional spot of fraternal bludgeoning. Essentially, Juggernaut isn't one of the big players for the simple reason that he doesn't feel like it.
* TheDreaded: Treated as this by Professor X in his first appearance, and rightly so. It took all five X-Men, Professor X, the X-Mansion's defenses ''and'' the ComicBook/HumanTorch lending a hand to defeat Juggernaut the first time. Even then, the heroes were nearly killed. To this day, if he’s not being worfed or a X-Men punching bag, he’s treated with absolute fear.
* DumbMuscle: ''How'' dumb varies DependingOnTheWriter. Sometimes he's simply BookDumb, other times his head's the only thing thicker in-story than his [[NighInvulnerability nigh-invulnerable]] body.
* EvenEvilHasStandards: He's got a fairly developed code of conduct as bad guys go. Theft and property damage might be A-OK in his books, but hurting kids, backstabbing people after they've helped you or hurting people purely for the sake of being a {{Sadist}} are all no bueno as far as he's concerned. During the ''Gauntlet'' storyline, he was even chosen by the Enigma Force to become the latest Captain Universe to repair the tectonic plate damage he had caused while digging his way out of concrete after his original battle with Spider-Man (albeit after the Enigma Force's originally chosen host preferred to try and vent his vendetta against the Juggernaut rather than complete his assigned mission).
* EvilRedhead: He has red hair, which matches his armor and helmet, and while more of a greyish character, he's still considered a bad guy.
* EyeScream: Was once inflicted on him by ComicBook/XForce's ComicBook/{{Shatterstar}}. Having a HealingFactor, Juggs recovered quick, but boy was he ever ''pissed''.
* {{Foil}}: To his brother Xavier. While Xavier is a paraplegic, telepathic GuileHero, Cain is an able-bodied, superhumanly strong brute.
* ForceAndFinesse: The Force to Black Tom Cassidy’s finesse. Unlike his partner, everything he does is through sheer brute force without any hints of subtlety. His UnskilledButStrong works hand in wand with Black Tom Cassidy’s WeakButSkilled.
* FreudianExcuse: The reason he hates his stepbrother so much is that their father always preferred Charles over Cain.
* FriendToAllChildren: Not all children everywhere, but generally he has a soft spot for kids and will pull his punches in battle with them if not refuse to fight them outright. This first cropped up with his befriending of Sammy the Squid Boy, but was later made a running trait during his time with the ComicBook/{{Thunderbolts}} and when he gave (surprisingly good) life advice to the kids of ComicBook/AvengersAcademy.
* GiantMook: Often used this way in the various X-Men video games. He's actually a StarterVillain in ''VideoGame/XMen1993'', for example.
* GoodIsImpotent: As noted below, Juggernaut's PowerCreepPowerSeep (towards the Seep side) were stated in-universe to be ''caused by'' his attempts to find redemption, as his powers stem from an evil entity who ''wants'' him to use them for selfish destruction.
* HealingFactor: It rarely gets brought up, because Juggernaut is almost impossible to hurt in the first place, but his ability to regenerate may even equal Wolverine's. In one famous incident, being reduced to nothing but bones not only ''failed to kill him'', he ''kept on fighting even as a bare skeleton''.
* HeelFaceDoorSlam: During ''ComicBook/WorldWarHulk'', the evil god who gave the Juggernaut his powers made him realize that the reason he was losing his powers was because he'd become soft and weak. In response, Juggernaut fully embraced his evil nature and the evil nature of the god who empowered him, returning to (and finally accepting) his true villainous self. But as of 2020, the Juggernaut has once again joined the hero side of things by joining the Punisher Kill Krew and later the X-Men up until Magik turned on him. He's still on friendly relations with his brother Charles despite not being allowed on Krakoa and he's had a moment with the ComicBook/SavageAvengers.
* HeelRealization: Goes through a twisted version after Charles' death. He decides that Xavier was the only person who ever tried to help him, and wants to make the X-Men pay for his death. He gets a further realization after he decided to go straight and work with online celebrity superhuman D-Cell in taking down the Immortal Hulk. The Hulk admitted demolishing homes and scaring people to death, but that was when he had a near-animal intelligence. Hulk tells Cain that he did the same thing and was conscious of how bad that was plus he only took on the Hulk because he was getting paid. The Juggernaut could only hang his head in shame.
* HelmetsAreHardlyHeroic: He and Magneto are the two main trope codifiers for this among X-villains.
* HeterosexualLifePartners: With Black Tom.
* HowTheMightyHaveFallen: The beginning of his HeelFaceDoorSlam begins in an issue of ''New Excalibur'' where the Wrecking Crew beat the pus out of him while lamenting how he used to be badass.
* HugeGuyTinyGirl: Often shown beside Nocturne in group shots, foreshadowing their dual HeelFaceTurn. They worked together after that too, with Nocturne becoming something like a replacement MoralityPet to Cain for a while.
* {{Immortality}}: He does not age, he requires no sustenance to survive, he is immune to poisons, disease, and radiation, he can survive as a skeleton, and he has a potent HealingFactor. These attributes, along with his extremely durable forcefield and armor, make him very hard to kill even for other heavy-hitters like Thor and the Hulk, and allow him to go on living for centuries.
* ImmuneToMindControl: Whenever he's wearing his helmet, at least.
* ImplacableMan: He literally cannot be stopped (one of his official superpowers is "once in motion, cannot be stopped" -- he took a mystic blast from ComicBook/TheMightyThor and it only staggered him for a few seconds), he's {{Nigh Invulnerab|ility}}le, and he officially has "infinite stamina". He never needs to stop. Ever. He doesn't eat, he doesn't sleep, he doesn't feel fatigue, he doesn't even breathe. Once, the demon D'spayr tried sucking all the magic and life away from Juggernaut. He managed to reduce him to a skeleton, but Juggy still kept coming, fueled by pure anger and rage. D'Spayr could have destroyed this skeleton too though, once he got over the shock it was still alive if not for a different CosmicEntity with it's own grudge against the demon taking notice.
* InfernalRetaliation: Happens to him frequently, see the page for ''some'' of these times.
* InvincibleBoogeymen: The Unstoppable Juggernaut got [[NamesToRunAwayFromReallyFast his name for a reason]]. Aside from a select few immensely powerful individuals, he is [[NighInvulnerability impervious to physical harm]], even more than Thor or Hulk. The one way to put a halt to his rampage is to get his helmet off and let the resident telepath subdue him or teleport him somewhere he can’t hurt anyone. Even then he’s managed to come up with counter measures to these weaknesses over the years.
* {{Irony}}: For how unstoppable he is, even the Juggernaut cannot escape the Crimson Bands of Cyttorak, a magical spell that's used to stop and restrain a target and is sourced from the same god that empowers him.
* TheJuggernaut: Well, [[ExactlyWhatItSaysOnTheTin it is his supervillain name]]. Not only does he have the above mentioned super-powers, he is ''literally'' unstoppable; once in motion, there isn't a power on the planet (and a good deal of the universe) that's supposed to be capable of stopping him. He once took a direct hit from a blast of "mystic Asgardian force" from [[ComicBook/TheMightyThor Mjolnir]] and it only succeeded in slowing him down for a few moments. And then there was the time when the demon D'Spayr vaporised his flesh and muscles -- cue the still-animate skeleton of Juggernaut continuing to come after him. His official superpowers include literally infinite stamina, and no need to eat, sleep, drink or even ''breathe''.
** This is made even worse in the ''ComicBook/FearItself'' event: Juggernaut becomes possessed by an ancient being in service of an Asgardian god, The Serpent, and becomes "Kuurth, Breaker Of Stone". In this incarnation he is even more unstoppable. Not only are all his usual weaknesses removed (telepathy and draining his powers did not work and teleporting him away will result in him teleporting back where he was before immediately), the X-Men's attempts had failed so much that ComicBook/{{Colossus}}, [[ComicBook/IllyanaRasputin Magik]] and [[ComicBook/KittyPryde Shadowcat]] had to appeal to Cyttorak himself to remove the Juggernaut powers from Cain and transfer it to [[spoiler:Colossus]] in order to stop him.
** He gets a similar, yet somehow STRONGER upgrade after he gets [[spoiler: his powers back courtesy of Cyttorak at the end of ''Amazing X-Men''. Due to Colossus trying to sacrifice himself by goading Cytorrak into re-empowering him and making him strong enough to kill the god, Cyttorak instead gives the power to Cain. The resulting behemoth is larger, more heavily armored, guarded against psychic abilities even without the helmet, and easily curbstomps the X-men in seconds, with Colossus barely defeating him by sending him tumbling of a cliff, a fate he escapes soon after]].
* KilledOffForReal: In the ComicBook/UltimateMarvel universe, during ''ComicBook/{{Ultimatum}}''.
* KryptoniteProofSuit: He usually wears a helmet that blocks out telepathy, which the X-Men usually work to knock off. After this happened enough times he started wearing a smaller, tighter skullcap under the main bulky helmet for extra protection.
* MacGuffin: The Crimson Gem of Cyttorak, a relic that imbues whoever holds it while invoking ritual words the power of "a human Juggernaut". Occasionally Juggs has had his power stolen by upstarts who find the gem, to the point of throwing it into deep space once to ensure no one would ever again have that opportunity. Being the manifestation of a malevolent deity, it turned out to be a little harder to get rid of than that.
* MeaningfulName: Let's put it this way; there's a ''reason'' he has the NameOfCain.
* MissedTheCall: It's occasionally stated that Cain wasn't the intended recipient of Cyttorak's power, but that it was meant for Charles Xavier. As one What-If story shows, this is a good thing, as an Xavier Juggernaut killed all non-mutant superheroes, nearly destroyed America and could only be stopped by being launched into space.
* MyGodWhatHaveIDone: {{Invoked|Trope}}: The demon D'Spayre, who feeds on, well, despair, was once able to physically manifest on Earth by tricking Juggernaut into thinking he had killed Black Tom Cassidy. Tom was alright but Juggernaut [[UnstoppableRage wasn't forgiving]].
* TheNeedless: The Juggernaut does not require food, water, sleep, or air; he's about as close to immortal as you can get.
* NewPowersAsThePlotDemands: He once demonstrated the ability to fire energy blasts from his forcefield, an ability that was never used before. It was never used afterwards either, suggesting it was retconned out of existence.
* NighInvulnerability: Juggernaut is, to all practical purposes, totally indestructible. While he can still be thrown, knocked back, or hit by blows, he cannot actually be damaged by brute force or physical in nature. Only magic can hurt him physically, he doesn't feel pain, regenerates any damage done to him... he's even got a forcefield he can erect to make himself ''even harder to hurt''.
* NoSell: During ''X-Men: Legacy'', when Sinister's Cronus Machine activates and tries to turn Cain into a new vessel for Essex, his Cytorrak given powers prevent it from happening (which, given Cain's lack of a mutant gene might well have killed him otherwise), but needless to say, Cain was pretty pissed.
* OlderThanTheyLook: Even without Cytorrak, he could pass for someone in his 30's when actually he's Professor X's ''older'' brother.
* OnlyInItForTheMoney: Occasionally, when Juggernaut is a hired gun rather than pursuing a personal vendetta, a bigger pile of cash than what his employer has offered ''can'' stop him.
* PatronGod: Cain gains his powers as the avatar of the extradimensional entity Cytorrak. His strength level is dependent on Cytorrak's whims, and he makes Marko perform feats of destruction and carnage in order to maintain his powers.
* PerpetualMotionMonster: He has been stated to have infinite stamina, does not require any sustenance, and can go for months without stopping.
* PetTheDog:
** In his villainous career, Black Tom was the only person he has shown concern.
** During his HeelFaceTurn phase, Juggernaut has also shown his soft spot for [[MoralityPet Squid Boy]] in Chuck Austen's ''X-Men'' and Nocturne in ''New Excalibur'' issues.
* PowerCreepPowerSeep: His power level depends on Cyttorak's whims. He can be weak enough to be trounced by the Wrecking Crew or strong enough to punch through dimensions. After Magik had removed his powers before the creation of Krakoan society, he was only able to regain a portion of his power by using shards of the crushed Gem of Cyttorak. He no longer has a force field, he's weaker and not as invulnerable and he now has to breathe, but he's no longer at the whim of Cyttorak.
* PowerLossMakesYouStrong: Despite being by all accounts an ordinary human prior to being empowered by Cyttorak, Cain has consistently maintained a level of SuperStrength even on the occasions when he has been depowered. He is also consistent in his freakishly large size, which was also a blessing from Cyttorak he should logically lose when depowered.
* PsychopathicManchild: Not to the same degree as the Blob, but Cain is somewhat underdeveloped emotionally and, Black Tom aside, seems to have an easier time befriending and relating to children that he does adults.
* RedemptionRejection: Played with post-''Comicbook/AvengersVsXMen'' -- it certainly ''looks'' like Cain has done this when he turns his back on the new peaceful life he has built for himself to chase after the Gem of Cyttorak again, but as it turns out [[spoiler:he's only trying to get it for the same reason that Colossus is, to destroy it so no one else can claim the Juggernaut power. Ironically, in spite of this Cyttorak chooses to empower him once more, making him fall into this anyway]].
* RedIsViolent: He has red hair, and he wears red armor and a red helmet. When reduced to a skeleton, the skeleton was shown to glow red from the red energy of the crimson gem of Cyttorak. He is also a brutish character.
* RevengeBeforeReason: Early in the All-New X-Men days, Juggernaut and Black Tom lure the X-Men into a trap at Cassidy Keep. Juggernaut doesn't particularly care that the team he's facing have no idea who he is or what he wants, save Cyclops. They're Charles's students, and that makes them fair game in his eyes.
* RoguesGalleryTransplant:
** He occasionally clashes with Franchise/SpiderMan and the ComicBook/IncredibleHulk.
** The entity Cyttorak that Juggernaut derives his powers from is actually one of the powers frequently invoked by ComicBook/DoctorStrange, and due to this connection the two characters have crossed paths multiple times.
** ComicBook/CaptainBritain and ComicBook/TheMightyThor have also had their share of tussles with him. As X-villains go, he ReallyGetsAround the superhero circuit.
* SignatureHeadgear: Juggernaut's helmet is easily the most recognizable feature of his look.
* SixthRangerTraitor: For Exodus' Brotherhood. Turns out he was TheMole the whole time.
* SleevesAreForWimps: Cain's outfits almost never have sleeves.
* SmarterThanYouLook: He might not be book smart, but DependingOnTheWriter, he can be more than just a meathead. He's usually shown to possess an average intellect, and was capable of creating a metal skullcap to provide additional protection from mental attacks.
* StatusQuoIsGod: After having his powers restored by Cyttorak in 2014, Juggernaut was shown to be stronger than he has '''ever''' been, to such a degree that the only way the X-Men could 'beat' him was by using the environment to drop him into the ocean and then escape. Despite this, in his next appearance Juggernaut had completely reverted to form as a petty criminal working with his longtime partner-in-crime Black Tom, and seemingly back at his normal power level to boot. Kind of a letdown after all that buildup...
* SuperSpeed: Juggernaut's hyper-strong muscles officially allow him to run at top speeds of 110 miles per hour.
* SuperStrength: With it he has immense strength that far exceeds the ability to lift 100 tons effortlessly. Due to the mystical nature of his powers, Juggernaut can increase his physical strength to immeasurable levels with a simple thought when he needs it. In this sense, Juggernaut has the strength-increasing option due his potential to draw on the limitless power of the mystical energy of Cyttorak, which makes him a truly unstoppable force. Juggernaut has been able to subdue through his physical force or knock out several powerhouses such as Thor, the Thing, Hulk and many others. Also, the limits of Juggernauts strength are unknown simply because of the fact it stems from his Cyttorak himself.
* SuperToughness: He's arguably even more well known for this than he is for his strength. Even without his helmet, armor, or forcefield, his skin and bones are durable enough for him to fight and defeat the Professor Hulk (who is somewhat stronger than regular Hulk's base powers and much smarter, though lacks his ability to increase his strength with anger) while shrugging off his blows. His armor is tough enough for him to take a beating from Thor for a full minute while his forcefield was disrupted. He can transform his civilian clothes into his armor at will and turn objects into new helmets in case his gets removed or destroyed, making it pointless to even destroy either in the first place. He has an incredibly powerful forcefield that is said to be completely indestructible to any physical blow and is powerful enough against energy attacks to take a low level Godblast from a severely weakened Thor (the same attack that at full power can even drive away Galactus). Finally, assuming you manage to get through all of this protection and natural durability and actually harm him, he can easily regenerate. All of this makes him possibly the most physically durable being on Earth.
* TranquilFury: After raging at and dominating a team of X-Men (while depowered!) Northstar [[PoorCommunicationKills finally spits it out]] that it was Cyclops who murdered Charles Xavier. Cain's response, after all that, is to simply narrow his eyes and drop his hostages.
* TokenHuman: Cain was one of the first non-mutant X-villains and has never been strongly invested in mutant rights, yet he is often affiliated with the Brotherhood in adaptations. The ''Film/XMenFilmSeries'' deliberately [[AdaptationSpeciesChange changed him from a mystically-empowered man into a mutant]] to avoid this trope.
* UseYourHead: He uses this mode of attack. In the ''VideoGame/CapcomVs'' series, it's his one and only Hyper Combo.
* UnskilledButStrong: Not much hand to hand skill despite former military service, but he has tremendous amounts of strength and divine support so he doesn’t need much. Thor once defeated him by sacrificing his own god powers to remove Juggernaut's and then casually beating Cain Marko to a pulp.
* VoodooShark: When he was portrayed as significantly weaker under Chuck Austen's pen, an explanation was crafted that his power goes up and down according to Cyttorak's wishes. This would be a serviceable answer... except that there were multiple occasions previously where reducing Juggernaut's powers or even taking them away would've been well within Cyttorak's interests, and yet there were no signs of him being any weaker than normal.
* WalkDontSwim: This is Juggernaut's default way of crossing water. One of the most famous examples of this was after his first battle with Franchise/SpiderMan in which he was buried in concrete so he simply tunneled his way into the Hudson River and walked out to sea.
* WhoWantsToLiveForever: In one ''ComicBook/WhatIf'' story he accidentally caused the nuclear extinction of humanity, condemning himself to a FateWorseThanDeath as he had his usual CompleteImmortality.
* TheWorfEffect: An oft-Worfed character, due to his great power and somewhat limited intelligence. Gladiator of the Shi'ar Imperial Guard gave him his most classic Worfing, shrugging off a blow from him and throwing him out to sea in a panel so memorable it was adapted into the animated series. Other villains have since tried to piggyback off that panel, among them Post, Onslaught and the Hulk in his Horseman of War and Green Scar incarnations. He was even Worfed by ComicBook/{{Superman}} in ''ComicBook/DCVersusMarvel'', knocked down by one punch.
* WorthyOpponent: Curiously, the Juggernaut has been known to show respect to people who put up a good enough fight against him. Although Colossus and Dazzler both lost their battles against him, they managed to win his respect.
* YouAreNotAlone: One storyline revealed that Juggernaut is an "Exemplar", a mystically-empowered avatar, and that there were in fact a number of other Exemplars in the world. Unfortunately, the other Exemplars ended up being CListFodder and this storyline fell by the wayside, but it's obvious parts of it were cribbed from by the writers of ''ComicBook/FearItself''.

!!Juggernaut provides examples of:

* InvincibleBoogeymen: The Unstoppable Juggernaut got [[NamesToRunAwayFromReallyFast his name for a reason]]. Aside from a select few immensely powerful individuals, he is [[NighInvulnerability impervious to physical harm]]. The one way to put a halt to his rampage is to get his helmet off and let the resident telepath subdue him or teleport him somewhere he can’t hurt anyone. Even then he’s managed to come up with counter measures to these weaknesses over the years.

* TheJuggernaut: Not only does he have the above mentioned super-powers, he is ''literally'' unstoppable; once in motion, there isn't a power on the planet (and a good deal of the universe) that's supposed to be capable of stopping him. He once took a direct hit from a blast of "mystic Asgardian force" from [[ComicBook/TheMightyThor Mjolnir]] and it only succeeded in slowing him down for a few moments. And then there was the time when the demon D'Spayr vaporised his flesh and muscles -- cue the still-animate skeleton of Juggernaut continuing to come after him. His official superpowers include literally infinite stamina, and no need to eat, sleep, drink or even ''breathe''.

* SuperToughness: He's arguably even more well known for this than he is for his strength. Even without his helmet, armor, or forcefield, his skin and bones are durable enough for him to fight and defeat the Professor Hulk (who is somewhat stronger than regular Hulk's base powers and much smarter, though lacks his ability to increase his strength with anger) while shrugging off his blows. His armor is tough enough for him to take a beating from Thor for a full minute while his forcefield was disrupted. He can transform his civilian clothes into his armor at will and turn objects into new helmets in case his gets removed or destroyed, making it pointless to even destroy either in the first place. He has an incredibly powerful forcefield that is said to be completely indestructible to any physical blow and is powerful enough against energy attacks to take a low level Godblast from a severely weakened Thor (the same attack that at full power can even drive away Galactus). Finally, assuming you manage to get through all of this protection and natural durability and actually harm him, he can easily regenerate.

* HeelFaceDoorSlam: During ''ComicBook/WorldWarHulk'', the evil god who gave the Juggernaut his powers made him realize that the reason he was losing his powers was because he'd become soft and weak. In response, Juggernaut fully embraced his evil nature and the evil nature of the god who empowered him, returning to (and finally accepting) his true villainous self.
* HeelRealization: Goes through a twisted version after Charles' death. He decides that Xavier was the only person who ever tried to help him, and wants to make the X-Men pay for his death.

** He has a weakness to psychic powers (only when his helmet is removed). Also, he has no way of getting around besides walking, so if you can teleport him or trick him through a portal, he's stuck wherever he ends up until he manages to physically walk himself back to where he wants to be. Also, his powers being magic based, powerful entities such as Thor can more or less neutralize them once they've figured out exactly how they operate.

* PowerCreepPowerSeep: His power level depends on Cyttorak's whims. He can be weak enough to be trounced by the Wrecking Crew or strong enough to punch through dimensions.

* MyGodWhatHaveIDone: {{Invoked|Trope}}: The demon D'Spayre, who feeds one despair, was once able to physically manifest on Earth by tricking Juggernaut into thinking he had killed Black Tom Cassidy. Tom was alright but Juggernaut [[UnstoppableRage wasn't forgiving]].

** As a ''human'' juggernaut, his soft tissues, particularly those related to his nervous system, are somewhat vulnerable even without employing magic or psionics. His eyes can be cut by mundane objects should they be sufficiently sharp(as Shatterstar proved) and though he cannot feel pain, strong enough concussive force to his head can render him unconcious.(a [[AntiMatter macroscopic annihilation reaction]] or [[StarKilling gamma ray bust]] is of course well outside of the range of most X-Men BUT is an energy level The Hulk or Thor could [[GatheringSteam potentially]] put out and was by the New God Mantis in a DC Comics crossover...[[WatchWhereYoureGoing which also knocked out Mantis]]). Atmospheric vibrations, such as ultrasound can also [[BodyHorror pulverize Juggernaut's brain and leave his body immobile]](which is how Nimrod dealt with him).

* TheWorfEffect: An oft-Worfed character, due to his great power and somewhat limited intelligence. Gladiator of the Shi'ar Imperial Guard gave him his most classic Worfing, shrugging off a blow from him and throwing him out to sea in a panel so memorable it was adapted into the animated series. Other villains have since tried to piggyback off that panel, among them Post, Onslaught and the Hulk in his Horseman of War and Green Scar incarnations.

* MyGodWhatHaveIDone: {{Invoked|Trope}}: The demon D'Spayr, who feeds one despair, was once able to physically manifest on Earth by tricking Juggernaut into thinking he had killed Black Tom Cassidy. Tom was alright but Juggernaut [[UnstoppableRage wasn't forgiving]].

* SmarterThanYouLook: He might not be book smart, but DependingOnTheWriter, he can be more than just a meathead. He's usually shown to possess an average intelect, and was capable of creating a metal skullcap to provide additional protection from mental attacks.

* AchillesHeel

Charles Xavier's older step-brother and antithesis, Cain Marko was abused by his father Kurt, leading him to torment his stepbrother viciously and developing a deep-seated grudge against him. When they were both in the army during the Korean War, they took refuge in a cave where Cain discovered a magical ruby placed there by an EldritchAbomination named Cyttorak that turned him into its avatar -- the Juggernaut. Unstoppable in every way but via psionics or advanced magic, the Juggernaut continued to be a thorn in Xavier's side for years, eventually getting trapped inside of the source of his own powers. Since he was let out, he fought briefly on the side of good, before embracing his true evil nature and returning to villainy. Despite being associated with the Brotherhood for ''years'' in adaptations, he was never officially a member until joining Exodus' Brotherhood alongside his longtime partner in crime Black Tom.
