"Juggernaut" is a word meaning "unstoppable". The Juggernaut is just that. It is often fixated on a goal, reaching somewhere that it shouldn't be, trying to accomplish something that the heroes don't want it to accomplish. In any case, it is moving ever and continually forward, letting no one and nothing stand in its path. Bullets? Pathetic. Rockets? Barely noticeable. Nuclear bombs? Might make him flinch* If only from the flash. , but don't expect the flames to stop him - And that's if you're lucky. The group of powerful heroes we've been following are nothing more than the Redshirt Army to this thing. You Shall Not Pass? It's going to. And it's ever, continually moving forward. You can taste the invulnerability of this thing.
It also helps the illusion of unstoppability if The Juggernaut is also The Voiceless. If physical attacks don't slow it down, then talking it down isn't going to work, either. It sometimes won't even attack, preferring to just plow forward, as if the defenses trying to stop it aren't even there. Those determined to make you fear them or mock your inability to scratch them will take their time. Stopping this thing usually requires a last second gambit, or a Deus ex Machina to defeat. If it ever appears again, Villain Decay is almost certain. After all, if the unstoppable is stopped once, that means it's not unstoppable anymore, right? An epic Not So Invincible After All moment will usually occur in the process.
Compare and contrast Foe-Tossing Charge, the usually heroic version of this trope. Also compare the Determinator who is powered by the sheer force of will. Compare Implacable Man which can be stopped but only temporarily. This may create a sense of false security in the Implacable Man's quarry that does not exist when dealing with a Juggernaut.
Also compare Super-Persistent Predator. Also the Perfect Play AI who usually applies only in gameplay terms.
Not to be confused with the 1974 film Juggernaut, which is about an extortionist who has planted time bombs on a cruise ship.

Anime and Manga
There isn't much that can stop Killy from Blame!!. In fact, the one thing that comes close to destroying him is an explosion that would make the Tsar Bomba look like a Sparrow's fart in comparison. Even then, this only destroys 40-odd percent of his body mass. How does he respond? By simply growing his body back and soldiering on.
Tetsuo from the movie AKIRA gains telekinetic powers, and promptly goes on a little stroll, destroying everything in his path. This includes tanks, soldiers, bridges, buildings, and even a Kill Sat.
Alexander Anderson from Hellsing, in his first appearance, takes multiple .454 Casull rounds to the head and continues fighting, even triumphing ever-so-briefly over Alucard. He continues to seem unstoppable up until his final confrontation with Alucard, where the trope is subverted by the vampire's mob of souls bogging him down. Not to say that Alucard does not look like one of these to his many enemies.
For that matter, Alucard too. He gets ripped to shreds by machine gun fire because it's fun. Just about nothing his enemies throw at him even slow him down. Justified for his maximum level, he borders on becoming an Eldritch Abomination.
Demons in Berserk are nearly impossible to put down. Nothing short of ridiculously thorough physical trauma can really stop one; Guts usually has to cleave one's head into pieces - repeatedly - and Wyald keeps moving until Nosferatu Zodd, another powerful demon, tears him clean in half.
Guts could also fall into this trope, as he walks around for two years killing and fighting these things.
Hao Asakura in Shaman King is definitely the most powerful shaman in the series. He shrugs off everything thrown at him and in the manga at least, destroys the most powerful of the X-Laws' Angels in only a single attack.
Most of the monstrous "Angels" in Neon Genesis Evangelion fit the bill to some extent, as they make mincemeat of the Tokyo-3 defenses.
Zeruel (the Fourteenth/Tenth Angel)takes more punishment than any other Angel in the series and is barely fazed by any of it, including an N2 bomb shoved through its AT Field.
If EVA-01 goes berserk, just pray that it'll stop soon
Lucy in the first episode of Elfen Lied, in a very graphic version of this trope. It's shocking to those who hear "Juggernaut" and think of the huge, muscly guy from X-Men. Lucy is a cute pink-haired teenage girl...until she rips you in half, spilling your blood everywhere.
Rikiya Gaou in Eyeshield 21 smashes through enemy defenses as though they were made of paper and is notorious for forcing opposing teams to forfeit due to his tendency to break the arms of their quarterbacks. Worf Effect took place when Kurita beat him, and then later, got beat up by Mr. Don in America.
Sloth from Fullmetal Alchemist is a very lazy Juggernaut. Despite being one of the core seven Dragons, he doesn't know or care about the Heroes, and just wants to rest. His laziness did not stop him from digging a circular tunnel all the way around Amestris and he's strong enough to shove tanks out of the way when he wants to. When the kid gloves come off and he finally starts exerting himself, Sloth also shows himself to be the fastest thing alive.
Faudo serves this role in the last arc of the Gash Bell anime (and the next-to-last arc of the manga).
Exodia is depicted this way in the Dawn of the Duel arc in Yu-Gi-Oh!, reflecting how the five component cards can result in the player gaining an automatic win in the game. When it fought Zorc Necrophades, the demon couldn't match it in terms of strength or power, but eventually realized that it's life force was drawn from Siamun Muran, the sorcerer who was controlling it. By striking Muran (whose body was mortal and far more vulnerable) Exodia lost its power and was quickly slain.
The Pig Deva Vikaralamon in Digimon Tamers was like this. His actual fighting abilities were rather low but he simply ignored everything his opponents threw at him.
The D-Reaper fits even better. Until the final episodes, absolutely nothing the protagonists threw at it seemed to so much as slow it down. To this day, after seven series, the D-Reaper still may be the unstoppable thing in the franchise.
Whitebeard from One Piece defines this trope. After receiving 267 slashes and stabs, 152 bullets, 46 cannonballs, pierced by a laser, and half his face burned off, HE NEVER RETREATED, as seen by his back which had absolutely no injuries, save for a couple that were just a result of being impaled from the front. And he died on his feet, like a true warrior.
Even more impressive, this is him elderly and after spending a considerable amount of time on life support. In his prime, he may have even been able to shrug all that off. And let's not forget his Devil Fruit, which is considered the most powerful of all Paramecia-types: the Gura Gura no Mi, translated as Tremor-Tremor Fruit, which gives the user the power to create tremors of strength akin to earthquakes by punching the air. The rumors about that fruit being able to destroy the world seemed to be proven true when he TILTED THE ENTIRE FREAKING OCEAN!
On the marine's side, we have Fleet Admiral Akainu, a man who transforms into a lava floe, and is just as unstoppable as one. Even when not taking into account this ability, his physical strength is unmatched, and the only time he was stopped, it was because he clashed with a bigger Juggernaut (Whitebeard). And even then, he was soon back up in time to murder some more pirates. And don't think reasoning with him will work, he's hellbent on exterminating every single pirate in the world, and will gladly incinerate anyone who stands in his way, including his own men.
Magellan is Impel Down's personal Juggernaut. Aside from being a massive brick wall of a man, his Devil Fruit means he can produce any kind of poison from his body, from tear gas to horrific corrosive poison that dissolves everything it touches, in amounts that range from small globs to veritable waterfalls that can flood whole rooms. He can also turn himself into poison that seeps through the skin, making direct attacks extremely dangerous without some kind of buffer. When Luffy stages a jailbreak, Magellan becomes a one-man Advancing Boss of Doom, and Luffy, the Blackbeard pirates, and many, many imprisoned pirates (including pirates so powerful that they're Unpersoned upon imprisonment, and whose release is a global catastrophe) have no choice but to run like hell.
The Spheres in Heroman have been dead set on crushing anything between them and their destination. Heroman barely slowed one down to get civilians out of the way in Episode 3; taking great damage to do so; and now there are five crushing their way to every populated continent in the world.
Younger Toguro of YuYu Hakusho is portrayed as this all the way up to his final moments. Toguro is a hulking monstrosity unfazed by even the strongest of attacks in the series, such as Genkai's point-blank Spirit Wave and Yusuke's mountain-crushing Spirit Gun, regenerating or growing stronger each time. He curbstomps every single opponent in his way (including his elder brother), terrifies Hiei and Kurama, two of the world's most notorious criminals, and when Yusuke finally approaches Toguro's strength and fires his strongest Spirit Gun yet? Toguro dies not from damage sustained in battle, but from overexertion due to holding back said Spirit Gun. He even fits the bill physically: he's already a muscular 7-foot monstrosity in his human form, and his demon transformations become more and more large and muscular as he shows more power, all the while gaining strength, defense, and speed with every transformation. Yet he's not the strongest demon in the series.
The Walpurgis Night from Puella Magi Madoka Magica. It's best described as devastatingly powerful magical flying fortress (which keeps laughing insanely), and it's plain unstoppable except with Madoka's power, but that's an entirely different can of worms.
Three words: Bazzet Fraga McRemitz from Fate/kaleid liner PRISMA☆ILLYA. She was already one in the parent series, but she deserves an honorable mention in this Spin-Off for Curbstomping Ilya, Kuro and Miyu, shrugging off all of their attacks, to the point they never won against her, they needed to trick her and place a Geas to prevent her from attacking.
The Destroy Gundam, the Gundam SEED Destiny-equivalent of the Psycho Gundam, is a battleship-sized mecha that was unleashed in Eurasia, causing millions of civilian casualties, and killing thousands of soldiers, before finally being stopped.
Gavrill from Franken Fran. The island she was trapped on got hit with a low-yield nuke. That only pissed her off.
A Certain Magical Index: Acqua of the Back! At least in his first appearance. The only thing that even slowed him down was going up against a Saint, and it took the Imagine Breaker combined with a spell known as "The Saint Destroyer" to stop him.
Toyotomi Hideyoshi is presented this way in the anime adaptation of Sengoku Basara. The second season consists of a single-long string of Hideyoshi curb-stomping every single person who opposes him without taking so much as a scratch, to the degree that Masamune defeating him with a single blow seems like a cop-out considering how one-sided every single battle he'd been in had been up to that point.
The Armored Titan from Attack on Titan. This unusual specimen is a 15m tall Humanoid Abomination covered in plates of thickened skin that allow it to shrug off cannon fire and just keep coming. Its first appearance involves charging and smashing through the internal gate of Wall Maria, an event that earns it legendary status among the survivors as an unstoppable horror.
Dragons in Fairy Tail can No Sell anything except attacks from other dragons and Dragonslayers (humans who learned magic from dragons). And even the Dragonslayers can barely scratch them unless they are really powerful. There is a reason they were on the top of the food chain 400 years ago.
As you might find out in the Video Games section below, the servants summoned in a Holy Grail war, as in Fate/Zero are implacable more or less by default. Two of them, however, stand out as true Juggernauts: Archer and Rider, especially the latter who isn't called the King of Conquest for nothing and demonstrates it very well by simply using his flying chariot to overrun naughty things like Caster's monsters or his opponent Berserker. The former on the other side has almost unlimited access to flying weapons to bombard his enemies (see Video Games section below for more details).
And then there's Berserker who is the walking embodiment of Crazy Awesome, mixed with Improbable Weapon User. He deserves this title probably most of all characters in the series due to his extreme perseverance (which helped him defeat Gilgamesh, among other things). And nothing will stop him from a duel to the death with Saber.
JoJo's Bizarre Adventure has two. First, one of the nastier villains, Cars, who became completely unstoppable after a while, shrugging off anything and everything, including patching the two weaknesses vampires like him usually have with some powers of his own. Only way they could get rid of him was toss him into an erupting volcano so it sends him into orbit, and that didn't even kill him. The other was a stand, Notorious B.I.G.. The owner went down like a punk, but the stand itself is death-triggered, and on top of that regenerated from all damage. So defeating the user wasn't an option, as he was already dead, and defeating the stand was impossible, as it simply regenerated from the damage and kept coming at the heroes. In the end, they dumped it into the ocean, and even then, the general area where it ended up became another Bermuda Triangle, as it occasionally ate a ship or two when it wasn't chasing down the waves.
Marvel's Celestials are each in their own Physical Gods that make Thor look like a fly in comparison (in both power and size), but the absolute most devastatingly powerful of them is Exitar the Exterminator, he has never actually been stopped.
The Trope Namer is a very old term, but Marvel villain The Juggernaut is usually the Trope Codifier. He is primarily an X-Men villain but his power has been tested against all of Marvel's Nigh Invulnerable characters at one time or another and he generally lives up to his Catch Phrase: "Nothing stops the Juggernaut". Even in the rare instances when somebody is capable of causing him physical harm, the Juggernaut is hardly slowed down and quickly regenerates. For example, on one occasion the Juggernaut fights a powerful demon who magically incinerates his flesh, muscles, and organs... only to have Juggernaut's skeleton keep marching forward to clobber the demon. The Juggernaut's power, at least in the comics, comes from the "Gem of Cyttorak", which makes him an avatar of the god of unstoppability. Most of the time, the only way to beat the Juggernaut is to have a telepath attack his mind, or to send him somewhere else, either by teleporting him or using Super Strength to either lift him up and throw him away, hit him before he can start moving, or judo-throw him across the planet. Since Cyttorak provided him with a helmet that blocks telepathic intrusions, and trying to send him away is only a temporary measure, the majority of any fight with the Juggernaut usually consists of the X-Men desperately trying to remove the helmet so that whoever is the resident telepath at the moment can subdue him.
The worst part is, the Juggernaut isn't dumb. In the classic two part issue where he fought Spider-Man, he told the hero that he learned from all the times where he was beaten by getting his helmet yanked off, so he welded it on with a laser torch. Another precaution he apparently took was to build a skullcap out of the same material as the helmet, and wear it underneath, for added protection just in case. Clearly, the fact that he's smarter than he looks makes him even more dangerous.
In the Fear Itself event, Juggernaut becomes possessed by an ancient being in service of an Asgardian god, The Serpent, becoming "Kuurth, Breaker Of Stone". In this incarnation he is even more unstoppable. Not only are all his usual weaknesses removed (telepathy doesn't work, draining his powers doesn't work, and teleporting him away will result in him teleporting back where he was immediately), but X-Men's attempts to stop him quickly turned into something akin to the SCP Foundation's attempts to terminate SCP-682. They even resorted to having Adam X use his power to ignite a victim's blood, roasting him from within on the Juggernaut. The result: now he's unstoppable and on fire, or at least able to burn anything he touched. Ultimately, they resort to informing Cyttorak that his avatar is now serving another god. Cyttorak is naturally displeased, and Colossus volunteers to be his new avatar, gaining the power to stalemate Kuurth.
On those occasions when Juggernaut's a hired gun instead of pursuing his personal vendettas, there is something that can stop him: a bigger pile of cash than his current employer has offered.
Prior to World War Hulk, Marko had decided to try to be a good guy, or at least less of a jerk. Unfortunately Cyttorak wasn't happy about his decision and withheld most of his power from Marko, resulting in his Juggernaut status dropping considerably. After his first encounter with the returned Hulk which ended in being soundly beaten, Marko swore his complete fealty to being the true avatar of Cyttorak, which pleased the god so much that he restored Marko with all of the Juggernaut power, raising his usual power set to frightening levels. Though he was defeated again (through trickery this time, as Juggernaut had the upper hand in the physical fight), Marko told the others not to look for him, as they wouldn't like what they would find, and left, still fully powered...
Galactus. And on the one occasion he was stopped, something even worse arrived to take his place.
The Death of Superman storyline featured a villain named Doomsday, who plowed through most of the Justice League in the months leading up the main event. When the two finally clashed, it took everything Superman had to stop him, and though he was successful, victory came at the cost of his life. Superman got better. Doomsday did too— eventually.
It should be noted that throughout the first 3 Superman comics that Doomsday had one hand TIED BEHIND HIS BACK.
It was eventually revealed that Doomsday's actual superpower was immunity: anything that kills him once can't kill him again. Getting beaten to death by Superman? Won't work again. Being tossed into the sun? Won't work again. Using time travel to deposit him at the moment of "big crunch" at the end of the universe's lifespan? Won't work again.
The Saint of Killers from Preacher has not been budged by a crashing pickup truck and stopped an advancing tank by kicking it. He responded to being hit with a nuke with a calm spitting and the quip "Not enough gun."
Neither Heaven nor Hell can contain this vengeful soul. When he arrived in Hell in his backstory comic, he put a literal spin to the term "When Hell Freezes Over". The only reason he doesn't kill Jesse Custer? He revealed that God set him up, and he came up with a way for the Saint to get even. That's where we see the part where not even Heaven can contain him.
The Shaggy Man in The DCU. The first time the Justice League fought him, the only way to stop him was to create a second Shaggy Man, then lure them both into a deep cavern, then seal it up, hoping the two incredibly angry monsters would just fight each other until the end of time. (And that actually worked... For a while.)
Black Adam counts as this in World War III of 52 where he spent several weeks circling the globe massacring everything in his path, and every superhero active could do little to stop or slow him down.
DC's multiversal Superboy-Prime has exploits in various crossover events that are worth mentioning. In Infinite Crisis, he shrugged off the entire extended Teen Titans, JSA, and Doom Patrol, got trapped in the Phantom Zone and got out, got trapped in the Speed Force and escaped, beat up on both heroes and villains in the Battle for Metropolis, shrugged off getting rammed into a super machine by a differentSuperboy, broke through a 300 mile long wall of Green Lantern willpower like it was made of glass, and beat the entire Green Lantern Corps on his way to Oa. The only thing that could stop him was two Supermen who had to fly him through a red sun. Even then, he didn't actually die and the Green Lanterns imprisoned him inside the red sun.
In the Sinestro Corps War, the eponymous villains of the event manage to break him out. He then goes on to easily fight off the nearly the entireJustice League in spite of not being at full strength, beats up Sodam Yat (who was supposed to be the strongest superhero in the universe), throws the Anti-Monitor into space like a rag doll, and then kills a bunch of Green Lantern Corps and Sinestro Corps members. He only gets beaten when a Guardian of a Universe blows himself up to stop him. He survives that too hopping between universes and killing superheroes and villains alike trying to find his "perfect Earth." This time around, he only gets stopped when a Monitor tricks him into fighting the Monarch, who's actually Captain Atom multiplied by 52. When Prime breaches Monarch's armor, the explosion is so massive, it destroys a universe. Of course, it's really too hard to keep a ridiculously powerful villain down.
In Final Crisis: Legion of 3 Worlds, it's revealed that Superboy-Prime managed to survive that explosion, having only become lost to time. He gets brought to the 31st century by another supervillain to do what he does best: commit senseless acts of murder. It gets to a point that Superman gets brought to the future as well to help defeat him. Here's the kicker: he, Superman, determines that the only possible way to beat Superboy-Prime is to try and redeem him. Apparently, they finally realized repeatedly blowing him up with cosmic explosions wasn't working too well.
He was finally subdued when he was defeated by the Teen Titans and imprisoned in the Source Wall.
Hulk can go into Juggernaut mode if you really piss him off. During World War Hulk the most powerful characters in MU, including Black Bolt, Hercules, Iron Man in Hulkbuster Armor, She-Hulk, Ares, Ghost Rider, Thing, Doctor Strange with the power of demonic superweapon, Sentry and Juggernaut himself couldn't stop him! Though Strange lost control and Ghost Rider had a lack of motivation rather than ability. Still, Hulk defeating Sentry was thought up until then impossible and when they thought all his energy was used up doing so he saw who was really responsible for bombing Sakaar and Hulked Out hard enough to nearly break Earth with his steps before he was finally stopped.
Word of God has it that Juggernaut was gaining the upper hand in that fight, and Hulk only managed to keep him away from the scene for some minutes (by pushing him away).
Superman's enemy Imperiex has destroyed entire galaxies and nearly ended creation itself by the time he comes to blows with the Man of Steel. He blows through FranchiseSuperman and the JLA and vaporizes Doomsday (he got better). He is finally killed by being sent back to The Big Bang, which was the only thing powerful enough to destroy him.
Marvel Comics villain Onslaught had near infinite strength, capable of going one on one when the Hulk had his greatest strength potential put out, not to mention knocking the Juggernaut, literally, across the country.
The Destroyer, a suit of magical armor created by Odin and other gods to battle the Celestials. As such, it is tremendously powerful and just short of invulnerable. Fortunately, it's mindless on its own, and can only be operated by the soul of another sentient, but it's still managed to nearly kill Thor several times.
What If Charles Xavier Became The Juggernaut? Basically, Juggernaut's power, but with the incentive and motivation to take initiative as a leader on his own, rather than just hired muscle, and eventually become a tyrant. He would become even an even worse extremist than Magneto. Solution: Launch him into space and hope he never finds a way back.
It turns out Xavier really was Cyttorak's first choice to become the Juggernaut.
Alternate Enerjak from Sonic the Hedgehog Archie Comics definitley qualifies. He manages to beat nearly every powerful character in his own timeline as illustrated by the large number of victims shown as his prisoners.
Willy Pete from Empowered. Unlike most examples, he hasn't shown himself to have unusual physical strength thus far... But that's probably because his body burns hotter than the surface of the sun, so anything huge he could pick up would just melt. As a "goddamn fire elemental", he is literally a force of nature. Kills without mercy, and capable of flash-frying an entire squad of supers before they even realize he's there.
In Scrooge McDuck stories by Don Rosa, the Gentleman Thief Arpin Lusene, also known as the "Black Knight", acquires a substance invented by Gyro Gearloose called Omnisolve that instantly annihilates anything it comes in contact with other than diamonds. (In the story where it originally appeared, it was poured on the ground and ate a shaft down to the centre of the Earth.) Wanting to end his career with the ultimate impossible theft, stealing all of Scrooge's money — or at least making it disappear so people will think he did — he coats a knight's armour and sword with diamond dust and then Omnisolve. With these, he's almost completely unstoppable, able to walk through any obstacle and absorb any attack, from cannonballs to gasses.
Godzilla is unstoppable when fighting humans because he shrugs off their best shot and keeps going. Often the only thing that stands against the big guy is another powerful kaiju or mecha, but even by giant monster standards Godzilla is this trope at times. Some of godzilla's more powerful rivals typically also display Juggernaut behaviour.
Star Trek movies - both The Motion Picture and IV: The Voyage Home feature unstoppable mystery probes heading straight for Earth.
As opposed to First Contact, Nemesis, and Star Trek (2009) which all feature unstoppable mystery ships heading straight for Earth.
The twelfth of the eponymous Thir13en Ghosts was named the Juggernaut. A seven-foot tall serial killer, the tale of his death is like that of a modern-day Blackbeard. But death couldn't stop his madness or rage, as he increased his kill tally four times over as a ghost before his capture.
X-Men: The Last Stand The Juggernaut could only be contained in shackles designed specifically for him. The police holding are heard warning others not to let him move, not even a little, because if he gets moving nothing will stop him.
Tai Lung: 1000 rhino warriors don't get a hit on him, the Furious Five can't stop him & even Master Shifu is defeated by him. Po & Master Oogway seem to be the only characters who stand any sort of chance against him.
The Luggage from Discworld books is quite implacable, and will follow its owner anywhere (even to the afterlife). In The Colour of Magic it gets bombarded with enough magic to cause reality itself to start breaking, yet survives unharmed (mostly due to being made from a completely magic-resistant material).
The Golems of the Discworld also qualify. They're not fast, but they're ridiculously strong, survive in just about any environment and never need to rest. As the Patrician says, "Four miles an hour is 672 miles in a week. It all adds up."
In The Black Company The Limper qualifies as this after he gets his new body in The Silver Spike. He REALLY qualifies after he comes out of the fondu pot at the end..
H.P. Lovecraft's Great Old Ones are immortal and undying (that is not dead which can eternal lie, and so on). While it's possible to damage them they regenerate any damage nearly instantaneously. In Call of Cthulhu Cthulhu got rammed in the face with a boat and suffered no permenent harm. In the work of another mythos-writer he's suffered a direct hit from a 300 megaton nuclear warhead and wasn't even slowed down, and in one mythos-themed RPG, rules state that if he is hit by a nuclear attack he gets vaporised, but reassembles 24 hours later and becomes radioactive! (Apparently the only thing worse than an eldritch abomination is a radioactive one.)
Though it has to be said that Cthulhu and many (if not necessarily all) of Lovecraft's other horrors, for all that they may be Nigh Invulnerable, show little in the way of juggernaut-style behavior — at least in the original works, they usually don't seem very interested in going anywhere in particular. They might well be unstoppable once they decided to, but we don't see it happen often; Cthulhu doesn't even leave his island and fails to as much as seriously damage the yacht that apparently passes straight through him, for example.
The titular creature in The Hound, on the other hand, is definitely this: it slowly but constantly pursues the protagonist. The only thing that ever slows it down is a second theft of its amulet, and after dealing with that thief it immediately returns to the protagonist (who eventually decides he would rather commit suicide than be caught by it).
Another Cthulhu Mythos example would be the Hounds of Tindalos. Immortal creatures, dwelling in the angles of time who relentlessly hunt down anyone who attracts their attention. They use corners and other angles to access our plane of existence and the only thing that might slow them down would be to plaster over the corners to make them into curves (which they can't access). But you'd better get all the angles.
The Reaper from The Elfstones Of Shannara. Swords break on its face, falling off a bridge only delays it, blasts from the eponymous Elfstones, which kill most Demons with ease, barely scorch its hide. It tracks Wil Ohmsford and Amberle from one end of the Westland to the other and never, ever, stops. Wil finally has to direct the Elfstones' fire into its face and down its hood from a few feet away in order to kill it.
In the Nightside series, there's The Walking Man, an agent of God that is sent to clean up sin in the Nightside - violently. Nothing can hurt him, nothing can even slow him down, until John shows him that what he's doing is wrong
The giant squid from Beast. It's all but unkillable. This more or less holds true in Real Life as well. The only thing that can kill it is a Sperm Whale, which makes sense, as that is its natural predator.
The Shrike from the Hyperion Cantos most definitely qualifies. Biomechanical, incomprehensible, almost god-like in power, and an implacable force of destruction.
In The Message, the fourth Animorphs book, Visser Three morphs a giant, untiring Sea Monster called a Mardrut to hunt the kids down with. They're only spared a messy death thanks to the fortuitous arrival of magic talkingwhales.
Legacy of the Dragokin: Ktonia's fight scene is, in a nutshell, her walking down the street while the heroes throw themselves at her in pointless attempts to stop or harm her.
In Terry Brooks' Witches' Brew, Ben and Willow are attacked by an unstoppable mechanical man created by Nightshade and Mistaya. Ben doesn't have time to summon the Paladin and is only saved by the Ardsheal, who is killed in the process. The chapter where it appears is named, appropriately, "Juggernaut".
The first appearance of the Borg in Star Trek: The Next Generation certainly makes them look unstoppable, but their second appearance really drives it home. The Enterprise is helpless to stop the Borg Cube from abducting Picard, and attempts to destroy it from the inside and a jury-rigged Wave Motion Gun are only minor setbacks. Later, the Borg destroy thirty-nine Federation ships without a scratch, and every planetary defense between Saturn and Earth crumbles without much of a fight.
And later, there was Species 8472, who waltzed through the Borg in the heart of the Borg's own empire like they weren't even there. They were that tough for about two episodes.
The Dalek in the "Dalek" episode of the new Doctor Who series, killing over 200 people in the process.
Dalekanium is possibly the best armour in the Whoniverse, rendering weapons from any time useless against the Daleks. On top of that they have a forcefield that vaporizes bullets a few inches from their shells, and they seem impervious to energy weaponry as well. If there's ever a weapon with enough sheer output to kill a Dalek, it either tends to be a one-shot that burns itself out in the process, or is carried by another Dalek, as their weaponmaking is even better than their armoring, and can thus one-shot anyone.
In the second season premiere of The Sarah Connor Chronicles, Cameron goes berserk and starts trying to kill John Connor, and proves next-to-impossible to stop, even with The Slow Walk due to a damaged leg. Eventually, the only way she is defeated is when John and Sarah crush her between two tractor trailers, and even then she's just pinned.
In the Back Story, the Earth-Minbari War went this way, with the Minbari playing the part of the giant cart. The Minbari had an advantage in hyperspace technology (allowing them to unleash devestating Hyperspeed Ambushes), as well as very effective stealth technology, meaning that they could wipe out half of a human fleet before the humans had a chance to acquire their targets.
In the show's setting, the Shadows' warships and later the Vorlons as well play this role versus the younger races in battle. Taking a Shadow Battlecrab out in open combat usually requires multiple ships acting in concert laying into it, or having frinedly telepaths lay down the Psychic Static to temporarily disable the Shadow ships.
The Meta has been nerfed, losing all the powers he copied along with the AIs in an EMP blast. He is STILL tough enough to massacre Agent Washington or take out Tex one-on-one. He survives several slashes from a knife, along with said knife being thrown into his chest, being stabbed by an Energy Sword, and four shotgun blasts. The only thing that manages to kill him is being dragged off of a cliff.
Episode 17 of Season 9 makes the damage he took in that fight seem trivial. He takes a sniper round to the chest, a full pistol clip point blank in the throat and is thrown into oncoming traffic at extreme speeds, this is WITHOUT any armor enhancements or AI like later in the series. The only permanent damage he takes is his loss of ability to speak.
Don't forget the Juggernaut of Khorne, a giant metal rhino that bleeds molten metal.
And on the subject of Khorne, there's his Champion, Kharnthe Betrayer, an unstoppable engine of destruction feared even by his fellow Berserkers due to his tendency to kill everything. During the 13th Black Crusade Abaddon, in an unexpected display of competence, merely pointed him in a direction and Kharn proceeded to "KILL! MAIM! BURN!" everything in his path, for the Blood god.
Titans. Immense war machines built in humanoid form. Most of the major races and forces of the galaxy utilize their own forms of Titans, except the Tau who relies on long-range hit-and-run. Emperor Titans, enormous walking-cathedral-mecha deployed by Imperium of Man, are about 55m tall and pack more than enough weapon to level a city.
Older editions of Dungeons & Dragons had a monster called the "juggernaut" that could roll over and crush anything in its path, and was almost impossible to stop when it got rolling. Its biggest strength was also its biggest weakness, since it was fairly awkward and had a hard time changing direction.
It's ridiculously easy to control with a simple command creature.
Forgotten Realms has Simbul, the Witch-Queen. Her three most known qualities are: 1) in raw power, the first among the spellcasters of her world; 2) very obsessive; 3) easily falls into absurdly destructive rages. When (Elminster In Hell) she had to rescue Elminster from Avernus and blasted her way through the initial crowd of The Legions of Hell, she just continued to fly to where she located him. After she tore a pit fiend to pieces without even slowing down, the local who abducted her lover began to wonder who the hell she was... and spend non-renewable sources in running all over the plane.
Another well-known example is Darksteel Colossus and its nastier poisonous brother BLightsteel Colossus. Really, there are a lot of examples. Virtually any nasty creature that possesses (or has been enchanted/equipped with) abilities such as Indestructible and Shroud/Hexproof is a Juggernaut.
A power that lets you do this is available in Mutants & Masterminds. So is an immovability power. (We think Chuck Norris dies if the two come together.)
Although technically the Unstoppable power is simply an extra option for the Immovable power.
The Star Trek-based game Star Fleet Battles has the Juggernaught, a regenerating mega-ship with the firepower of a Starbase capable of taking on an entire fleet.
Somebody once made an experiment that created one - he adapted Cthulhu to Dungeons & Dragons and set him against a team of players with most iconic D&D characters, boosted up to 20th level each, with the addition that every time one of them died, they got another one. Cthulhu killed 13 of them and was defeated by a spell that imprisoned him, because nothing else worked.
The New World of Darkness sourcebook Slasher incorporates many of these elements into the Mask Undertaking (the unholy lovechild of Michael Myers and Jason Voorhees conceived after a night of indulging in PCP). Voiceless? The Mask loses all capacity for literacy and intelligible speech once it achieves its final metamorphosis. Unable to feel pain? Only because it's hinted that the mere presence of humans causes it blistering pain that no other sensation can match. Unable to be killed? Any attack against it — from a sucker punch to a shotgun blast to the head to an unleashed flamethrower — will only fill one health box.
The Yozi Isidoros, the Black Boar That Twists The Skies, from Exalted. Isidoros' title isn't just boasting - he was able to push the moon and stars out of his path.
There is also a creature called Juggernaut, a vaguely-living monster that looms over Thorns, but rather than being an unstoppable trampling death-engine with no limits, it's enslaved to the Mask of Winters and would really like to be freed - one way or the other.
In Warhammer, Skaven players can field the Hell Pit Abomination, which is basically a Clan Moulder mutation Gone Horribly Right. It's absolutely massive, can kill nigh-on anything and is tough as hell to beat. And the worst thing? On death, it gets to use it's special rule Too Horrible to Die to roll on a table- on a 5 or 6, the creature gets right back up, regardless of how it died, completely healed.
There's also the Regeneration rule, which, unless the attack is Flaming or ignores it for any reason, allows the user a 50% chance of ignoring any attack because they just keep growing back.
The Empire Steam Tank. With decent firepower, of course.
Diplomacy strategy often calls a Russia-Turkey alliance the Eastern Juggernaut because both countries are against the side of the board, meaning if they cooperate they can focus their efforts expanding west.
"Ogre" from Steve Jackson Games. One player would set up the board with a layered defense of tanks, powered army infantry, and artillery. The other would have an Ogre (a large robotic tank in the style of Keith Laumer's "Bolo."). The Ogre's objective was to break through these defenses, and has a good chance of doing so if competently played.
Berserker aka Herakles from the visual novel Fate/stay night,especially during his fight against Gilgamesh in UBW Route.His opponent is the world's First Hero with access to stronger versions of almost all Noble Phantasms that ever existed.So what does Berserker do? He literally storms his way through volleys of highly dangerous noble phantasms,all the while shielding his frightened master with his body.Gil gets angrier with every passing moment & showers him with volleys of NPs. He shrugs his way through them. Then he is trapped by Enkidu,an ancient chain specifically designed to restrain beings of divine origin, like Herakles and skewered by another volley of NPs. Berserker's immortality had run out by then. So what does he do? He breaks the God binding chains with raw strength & charges at his enemy,once again. In the end, Gil gets really tired of this & pierces Herakles's heart with Gae Bolg, the spear designed to reduce the victim's hitpoints to 0. Even then Berserker keeps himself alive with sheer wilpower long enough to ensure that his frightened & injured master could die in peace,before fading away.
Gilgamesh himself also is a great example of this trope, as heīs capable of smashing through every other character in the game at not even a fifth of his full power and is almost completely invincible due to his golden armor, which can block a salvo of about 50 hits from Saber without a scratch. He only gets injured twice in the entire game, Once when Shirou using Avalon to reflect a Sword Beam back at him, though he is still mostly unharmed and in Unlimited Blade Works where he loses an arm to Shirou (since he didnīt put on his armor). That last one doesnīt even slow him down, and it takes a BLACK HOLE manifesting inside his body to actually give him pause... until he starts dragging his way out of it with the previously mentioned chains. Heīs finally consumed by the black hole because Archer came and threw a dagger into his face. Had THAT not distracted him for a second, he wouldīve climbed out anyway. Letīs just say thereīs a reason this guy is an Ensemble Darkhorse.
Archimonde, the Big Bad of Warcraft III, becomes the Juggernaut for the last half a minute of the game's final mission. He charges at you, summoning demons into your base, casting a spell that kills everything with one hit and blasting everything with a powerful attack. However, the mission is won at this point, since he can't get to the end of the course you are defending in the remaining time.
One of the more infamous "trash" encounters in World of Warcraft, the Throne of Thunder's Gastropods, are basically slow-moving giant snails that are inordinately tough but lack any kind of standard attack whatsoever. They can barely move above a walking pace and are subject to normal aggro rules, so their path tends to be very predictable. However, they will eat anything they walk over, instantly killing it. Despite their drawbacks, casualties to the "snail boss" are consistently high (and embarrassing).
Modern Warfare 2 features in the Special Operations mission the Juggernauts, soldiers fitted in heavy armour capable to absorb insane amounts of damage, including grenades, C4 and MG bullets. Usually the only way to kill them is to use heavy weapons like RPGs and some rounds of sniper rifles; the problem is that they charge on you on sight, and since they are armed with powerful weapons and have a nice firing accuracy it demands a lot of effort to turn them down.
It should be noted that their suits resemble modified heavy bomb squad armour. They reappear in Black Ops, where their armour was changed to resemble some modified riot gear (however with a military helmet).
In Modern Warfare 3, Price and Yuri don Juggernaut armor and blast their way into the hotel where Makarov is hiding.
At the end of Legacy of Kain: Soul Reaver 2, Raziel becomes The Juggernaut when he picks up the Reaver Blade, turning him entirely invulnerable, and making the rest of the game - a long series of bosses - a complete walkover. And he can't drop or lose the blade.
In the original Vandal Hearts, a long series of optional quests makes it possible to transform the main character into the Vandalier, with incredible defenses, an evasion rate that bordered on Made Of Air, and the ability to cast any spell in the game (including some utterly broken ones that are usually only available to the enemies) - a Game Breaker if there ever was one. Everything in the game beyond that point, including the final boss, is a joke.
In Shadow Hearts: From the New World the de facto Big Bad, Lady, appears to be completely unstoppable, says almost nothing, and seems to have no real goals. She kills people largely because they happen to be in her way. She also sometimes kisses people.
Freespace 2 features the Shivans' Sathanas, which is even classified as a Juggernaut as it's bigger than anything the Galactic Terran-Vasudan Alliance has save their own Juggernaut-type ship (which is admittedly not as powerful). It grinds through the GTVA's star systems until it's finally destroyed in a climactic showdown (the mission is even named "High Noon"). And then it goes From Bad to Worse - a fleet of the things shows up, destroys the good guys Juggernaut, and the Shivans blow up the Capella star system.
Shivans are rather fond of this trope: the first game featured the Superdestroyer Lucifer, a super-destroyer with shields so powerful that literally nothing in the Allied arsenal could bring it down. The Lucifer glasses Vasuda Prime, and sets course for Earth, destroying everything in its path. Then scientists uncover ruins of the Ancients—a race destroyed by the Shivans thousands of years ago—who left behind a dying message in the hopes of aiding some future race: Shivan ships can't use their shields in Subspace, and ships can be tracked into subspace (the means for which is provided in the message). Using this, you scramble a last-ditch attempt to pull this off, destroying the Lucifer just as it nears the exit to Earth. By the sequel, a GTVA destroyer is a match for a Lucifer-class ship, and the GTVA Colossus—a Juggernaut in its own right, designed to engage multiple Lucifer-class ships at once and win, embodies this trope for any ship that isn't Shivan. The Shivans, not to be one-upped, reveal the Sathanas in the sequel, which is somewhere around five kilometers in length, two-three kilometers in height and width, and bristling with twice as much firepower as the Colossus. Destroying one is a major effort in itself, even for the vastly-stronger Alliance in the sequel. When several of them start showing up after that, the GTVA command knows to prepare to destroy both jump nodes connecting the adjoining system to the rest of GTVA territory. This move saves them and is completely vindicated when EIGHTY of them show up, and then begin to make Capella's sun go supernova. Given how casually the Shivans sacrifice at least a dozen Sathanas's, several cruisers, and some destroyers, one has to wonder if they have something even bigger.
In Gears of War the Berserker fits this trope to a tee. She (yes, she, as she's apparently a normal drone - only female) is blind, but has an acute sense of hearing that will lead her to charge towards the noise, and nothing can stop her - the only way for Marcus and Dom to kill the Berserkers they encounter is by using the Hammer of Dawn on one and when encountering one on a train, tricking her into either running onto a train carriage which is then severed from the train or a pile of explosives (if this troper's memory serves him correctly).
Left 4 Dead gives us their version of The Juggernaut in the Tank, a zombie that can best be described as at least 600 pounds of undead muscle and condensed hatred for anything that still has a pulse. Walls? It smashes through them. Cars? It punches them at the survivors. The only way to come out of a fight with a Tank is lots of firepower, LOTS of running, and good teamwork.
Chargers, from Left 4 Dead 2 are a minor example. They can charge through doors and windows and such, and have more health than any of the other normal special infected, but what qualifies them for this is what they do after they've charged a survivor. There is absolutely no way to get a Charger to release the person it's grabbed. Either it dies, or they do. And the extra health means that you can empty entire magazines of some weapons directly into them without killing them.
Legend of Legaia has a type of Seru known as Juggernaut... and the one you meet is the Big Bad's partner. Luckily, you never have to fight him.
Rocky from Adventures of Lolo. While he can't kill Lolo, he is capable of overpowering the blue guy, and is almost never found in the same room as Magic Shots. Even if Lolo does find a Magic Shot or two, firing them at Rocky won't turn him into an egg, like most other monsters. If Lolo is backed into a corner by one or more Rockys, the only hope for him is to use a Puzzle Reset and try again.
Alex Mercer from Prototype has access to hyper-fast Le Parkour moves (he'll even climb a building running at full speed), but if traffic is too big, he can shift his arms into shields to push cars away (and crush people) or transform his whole body into a very thick armor made of his own hardened tissue.
Not to be confused with the enemies called Juggernauts, Marathon had a Dummied Out monster called the Armageddon Beast that would basically be this.
Dog in Half-Life 2 and its Episodes is a heroic version of this trope; literally nothing in the game can stop him. Combine soldiers? Crushed. APC? Hurled aside. Dropship? Climbed on top of as it attempts to flee. Strider? Dog tears out its Goddamn brain. He even manages to injure one of the horrifically powerful Combine Advisors at the end of Episode Two, though it's easy to miss through your tears.
Sovereign. During the battle for the Citadel in the first game, after Sovereign appears, the massed warships of the Citadel Council open fire on him. Sovereign doesn't even bother firing back; he just plows right through them and doesn't even get scratched.
Reapers in general can barely ever even be slowed down, let alone destroyed. On the rare occasion we actually see one get destroyed, the sheer amount of firepower aimed at it is nothing short of mind-boggling, and would probably be enough to reduce most conventional fleets to dust.
And that's just in space combat. Those same Reapers can also make planetfall, dwarfing high-rise towers as they lumber across a cityscape and lay waste to everything, often in large numbers.
Mass Effect 2's Shepard is definitely this, even alone, tears through enemies as if their armour was made of paper. Being enhanced through cybernetics and having enhanced tech makes about 50 enemies like a 4 minute fight. Takes a Reaper tech device at full power to bring him/her down. Even sedated, it doesn't stop him/her for long. In fact each dose of sedative had to constantly get increased because Shepard grew immune to it.
Mass Effect 3 brings us the multiplayer-only Krogan Vanguard class, aka the murder train. And then to top that, the final multiplayer DLC gives us the Geth Juggernaut, a class that can tank anything thrown at it, and gives absolutely zero fucks to anything.
The Juggernaut (basically a playable version of the Geth Prime mini-boss) is a ridiculously slow heavy weapons platform that can't run, dodge, roll, take cover, or do much of anything except shoot... and survive. They have the toughest base shields and armor of any class and can deploy large hexagonal shields onto the battlefield to protect themselves and teammates. More importantly, they are completely immune to staggers and sync-kills, which are normally instantdeader-than-death to players. Its other two use-activated powers are Geth Turret, which deploys a mini turret that refills the shields of the Juggernaut and its allies if they're nearby, and Siege Pulse, which creates several charges that take the form of a series of brackets on the Juggernaut's right shoulder and make the Juggernaut even more resistant to damage than it already is. And if that wasn't enough durability as it is, the Juggernaut's heavy melee attack is a electrical arc that paralyzes the enemy hit by it and refills the Juggernaut's shields as long as the attack is going off. One of the most common uses of the Juggernaut is a sort of mobile fire-barricade for allied troops; the Juggernaut physically blocks a corridor or choke point with its body and shields, while allies pour fire around it at the helpless enemy.
In general, the krogans have a repuation for this, having evolved on a Death World. They are huge, immensely strong, often short-tempered, and their bodies have such features as redundant hearts. In-universe materials indicate that krogan in battle must be defeated either through immense skill or with the proper application of high explosives.
Similarly, the elcor are Gentle Giants and are very slow to anger... but if they're forced into a fight, they are a terrifying force. The average elcor, being a Heavy Worlder, has enough arm strength to punch through a bulkhead and the personal weapons they carry into combat have been compared to the artillery used by other races. One elcor proudly notes that he has heard his species' soldiers described as "living tanks" by others. Too bad we never actually get to see them in action.
LIBERTY PRIME in Fallout 3. When he first appeared, it was a Mass "Oh, Crap!" moment for the Enclave. The Brotherhood doesn't need to do much fighting while he plows through the Enclave, one-shots their Vertibirds, and dispenses with their forcefield blockades simply by walking through them.
If you weren't able to cripple limbs, Deathclaws would certainly be this. They can take you out with a couple of hits since their claws completely ignore armor as if you weren't wearing any. And once they spot you, they sprint towards you and their hitpoints are far too high for you to kill them using anything short of the alien blaster or fat man before they close the distance. The only way to kill them safely is to cripple their legs with a sniping weapon before they notice you. Unless you have a dart gun, that is. Unfortunately in Fallout: New Vegas, they axed the Dart Gun and made the Deathclaws even tougher. Fitting this trope even better is the Legendary Deathclaw from that game.
In another interesting example, Yao Guai, giant mutated black bears, are nearly as powerful as Deathclaws, and with a certain perk, can fight on your side. Like Deathclaws, they can be taken down easily by shooting them first with the Dart Gun, which instantly cripples the legs of these fast powerhouses.
Then there's the Albino Radscorpions, only encountered if you have the Broken Steel DLC. They have loads of health, staggering offense and damage resistance, and unlike the Deathclaws or Yao Guai, cannot be crippled with the Dart Gun. Good luck.
And finally, we have the Feral Ghoul Reaver. Not only does this thing send you flying as far as a deathclaw can with its also armor-piercing Deadly Lunge, but it also can Flash Step spaz and become nearly invincible. The twitchy dance of doom that the F3 Reaver does is ultimate Nightmare Fuel. Later, in New Vegas, the Reaver becomes a simple, non-threatning mook.
Vampire: The Masquerade Bloodlines gives us the werewolf; your weapons do nothing, your Disciplines do nothing, and the only way to survive the beast is either to evade it for four minutes and escape on the tram or crush it to death with the doors to the observatory.
The Hybrid Reaver in the secret mission in Starcraft II. While the ones fought in the Protoss mini-campaign are killable, this one will shrug off anything done to it. The only weapon that is effective against it is a device that slows down time — this only slows it down for a few seconds. Once it appears, the only goal in the mission is to get the hell out of Dodge.
The Ultralisk in the cinematics. It can shrug off Siege Tank fire and swipes aside a Viking in one hit without breaking stride.
It's not too hard to make the Grey Warden into a Juggernaut if he/she uses an Arcane Warrior build. It's ridiculously easy to do this in Awakening thanks to the new equipment available and the new Mage spells/talents and Battlemage specialization, all of which seem tailormade to make Arcane Warriors even more broken. Soloing everything on Nightmare with the possible exception of the Bonus Boss becomes utterly trivial. As a possible Lampshade, the unique set of armor that can be found in the same area as the Arcane Warrior specialization is called the Juggernaut set.
The Nemesis in Resident Evil 3: Nemesis is a walking juggernaut of Nightmare Fuel. He can appear anywhere, will relentlessly pursue you from room to room, and gets back up quickly after you knock him down. Don't forget the rocket-launcher on his arm.
Mr. X in Resident Evil 2 is also a walking dispenser of pain and terror. Smashing through walls in the police station just as players pass by, and the cut-scene where he stands back up repeatedly...
The Ultimate Chimera from Mother 3. Can nothing kill it?
The mutated rancor in Jedi Academy. The whole level it's on is all about running away from it as it ploughs through more regular enemies and breakable scenery. When time you make it to a new area that is inaccessible to a creature of its size, it will bang on the wall or other obstacle until its shatters, and go on coming. It's invulnerable to all attacks (except the trick at the very end that kills it, of course) and possesses some mean ones of its own.
In Batman: Arkham Asylum, Killer Croc technically qualifies. You never actually BEAT him, you either set off a shock-collar that throws his whole nervous system out of whack for a few seconds so he doesn't run you over like a bulldozer and bring you home for dinner, or blow out a floor to send him hurtling to the stygian depths. After which he can be heard YELLING UP AT YOU for a few seconds. And depending on the random generator during the ending sequence, you might see his hand burst from the water to grab a surviving case of Titan.
Evil Otto from Berzerk, a taunting, invincible smiley face.
The game Juggernaut. Okay, so there aren't any characters that fit the description, but when you get to the end and realize that the priest who has been helping you is an unstoppable, evil force bent on selling souls to Satan and corrupting innocent people, the title makes more sense.
inFAMOUS 2 introduces the Beast, an incredibly powerful Conduit. His fire powers are powerful enough to destroy entire cities, and any damage done to him is quickly healed. The entire game is spent trying to get Cole powerful enough to face him. During this time, the Beast is slowly making his way down the United States' east coast to kill Cole, destroying everything and everyone in his path. The only way to kill the Beast is to use a very strong Power Nullifier, at the cost of killing several thousand innocent people.
The Destroyer in The Legend of Spyro, it's an ancient Eldritch Abomination the size of a mountain that is virtually unstoppable once it gets going and if it's allowed to reach the volcano it emerged from again, it starts The End of the World as We Know It. The only way to hope to defeat it is to slow it down long enough to destroy every single Dark Crystal on it's massive body, including going inside it and blowing up it's heart. And even that fails if the Big Bad just so happens to have a backup crystal handy... The Golem probably counts as well, as it's virtually unstoppable until a lucky attack uncovers it's brain, allowing Spyro and Cynder to kill it.
The SA-X in Metroid: Fusion, an alien duplicate of Samus at her most powerful. (Samus herself has just picked up the Bag of Spilling.) It can't be fought, only escaped, until the very end — and it puts up a hell of a fight then. The ultimate proof of its power can be seen here, where a clever player manages to Speed Boost right into the SA-X... and through it.
Considering her incredible attack power and ridiculous amounts of health, Samus herself would qualify as this in most of the games.
The (mechanical?) monster from Dungeons & Dragons mentioned above makes an appearance in the D&D Real-time Strategy game Blood & Magic in the final levels of one of the campaigns.
City of Heroes has a Juggernaut in the Minds of Mayhem trial: the Player Characters have to find a way to stop a psychic projection of Mother from reaching a symbol of the local Sentient Cosmic Force, or that section of the raid effectively resets. Mother's projection does not attack during this phase; it slowly...methodically...floats...toward its goal, and can only be stopped by using manifestations of its own nightmares against it. While it's not as invulnerable as other examples, Mother's manifestation is still almost impossible to defeat in time without using this little trick.
The previously Glass Cannon Hunters in the Halo series were upgraded to this in the later games, especially Halo: Reach, where they are outright Lightning Bruisers that are very difficult to hit in their weak points, take buckets of damage, and will chase you down and One-Hit Kill melee you once you get close, if their Fuel Rod Cannons don't kill you first.
Command & Conquer: Red Alert 3Uprising the Empire Giga Fortress a massive naval unit that can transform into a flying fortress. It can dish out an immense amount of firepower on both forms, and can take a heck load of damages.
Team Fortress 2 has the Tank in Mann vs Machine. There is absolutely no way to slow it down, has nothing resembling a weak point, and will mindlessly plow into anything in its (preset) path until it reaches your base and drops a bomb inside. Worse yet, it acts as a distraction for the robots who can attack you, and carry their own bomb. Taking it down usually requires several crit canteens and focused fire from everyone on your team.
Alexander, the murderous, genocidal General Ripper villain from Inotia 4. He arrives through a faulty portal gate that was explicitly stated to have killed a good percentage of his men, effortlessly bypasses ancient elven enchantments that hundreds before him fell victim to, shrugs off an avalanche, curbstomps the protagonist, and THEN decides to drink a potion that makes him 10 times stronger, so he can massacre an entire village for the heck of it. Ancient guardian machines go haywire when he approaches so his men can effortlessly loot them. And that's BEFORE he turns himself into a dragon. His mission? Kill a sick woman for not endorsing a war. This guy eats terminators for breakfast.
Kratos from God of War. Once he's fixated on a goal, nothing will stop him. Even if you manage to kill him, he'll climb back out of Hades even angrier than before.
NieR has several boss Shades that fall under this.
The Disc One Final Boss is a massive Shade called the Knave of Hearts that attacks Nier's village. It shrugs off most of Nier and Kaine's attacks, even their superpowered finishers, until they team up to cut it in half and shoot it full of magical lances...and even then, all that destroys is the main body. The head still remains, and it proves to be so hard to kill that Kaine allows herself to be petrified just to lock it away. After a Time Skip, Nier shows off how much stronger he has become when he brutally dispatches the Knave so he can free Kaine.
The Giant, which can take huge amounts of damage before dying & kill your units with 1 slam. The Titan is even worse, because it has twice as much health & can smash 3 minirobots with 1 attack!
A lot of the enemies in Plants vs. Zombies could count(since they are zombies), but the giant hulk known as the Gargantuar certainly takes the cake. It has so much health that it requires 150 points of damage to kill(instant kill plants only deal 90 damage) & it smashes your plants instead of eating them. The Giga-Gargantuar is even worse because it has twice as much health & moves just as fast.
The Shagohod from Metal Gear Solid 3: Snake Eater. While its Metal Gear successors have pretty obvious and vulnerable weak points (or "character flaws"), the Shagohod is a bulky, rocket-fueled behemoth of a tank. Even blowing up the entire building it's in with C3 doesn't put a dent in it, nor do any of the infinite RPG rounds you can pump into it during the ensuing motorcycle chase. The only reason it gets destroyed in the end is because its driver is forced to detach the back half of it to avoid falling into a river, exposing weak plating.
In one of the TV commercials, a P.E.K.K.A is chasing a butterfly with its sword. It doesn't notice the arrows from an archer tower nor the fallen trees (and said tower) it carelessly left in it's wake.
Interestingly, Yurnero the Juggernaut from Defense of the Ancients: All-Stars is more complicated than you'd think. As an agility-based hero, he is fast, but squishy, rather than the muscle-bound brute you'd expect from hearing the name. He does live up to his title in a certain way, however, since one of his abilities give him temporary magic immunity while in use, and another flat-out makes him invulnerable (and both dish out a lot of pain on anything around him).
Iosa the Invincible, from Iji. She gained her title by taking a Planet Buster to the face and survive.
Cans from the Midnight Crew Intermission in Homestuck is the biggest and strongest member of The Felt and, along with Clover (who is too lucky to be killed off conventionally) and Snowman (who can't be killed without taking the rest of the universe with her), is one of the few members of the gang that does not get killed by the Midnight Crew. He can easily plow through walls Kool-aid Man style at lightning speed. Even worse, his time related power lets him literally punch people into next week or into a different calendar year. The Midnight Crew are understandably reluctant to face him.
Suddenly the whole vault room is shaking... It sounds suspiciously like Cans is about to plow through the wall Kool-Aid Man style. You pray to God that it is not Cans about to plow through the wall Kool-Aid Man style.
Jones from Gunnerkrigg Court wouldn't look like she would fit this trope at a first glance, being a rather short, quiet and unassuming woman, but there is no known force in the universe that could even cut her hair, let alone pierce her skin, and when she's determined to go somewhere, even concrete walls barely slow her down.
SCP-096 whenever in the midst of an Unstoppable Rage. When someone sees its face or some recorded image of it, no obstacle or attack can keep it from killing and [DATA EXPUNGED] them. The best the Foundation can do is try to slow it down slightly while moving Innocent Bystanders out of its path.
SCP-076-2, "Able", is also very difficult to destroy, able to continue its killing spree even under heavy fire. Once, the Foundation had to detonate an on-site nuke, killing all personnel present there, just to stop him. In addition, he cannot be killed permanently, as he will be regenerated by SCP-076-1. If you're lucky, the process could take up to 25 years. If you're not lucky, "Able" could be revived in only six hours!
SCP-682 is so unstoppable that the wiki has an entire page dedicated to failed attempts to kill the thing. It was once thrown into the sun (noncanon story, but still), which only caused him to fly back to Earth from space and attack the Foundation again while ON FIRE. One story showing an alternate universe suggested that it would take an entire planetwide army of unstoppable monsters like him to take him down for good.
They also pitted it against 096 above. 27 hours of fighting later, 682 was still walking even with 85% of itself completely gone, and 096 preferred to try and claw out its own face rather than keep trying to kill the thing.
Malachyte from Suburban Knights. This is most prominent when he's seen crossing a road, and a car that collides with him just outright explodes and he just keeps walking.
Worm features The Siberian. Silent, her power makes her a literal unstoppable force to the point that she and anything she touches can become completely immune to external effects. She doesn't bother with clothes and fights mainly by running intothe enemy.
There are also the Endbringers. Even the combined forces of the strongest heroes and villains in the world can barely impede their progress, and even when one of them was reduced to a flaming skeleton by a particularly power attack, it was still advancing.
Maine from Red vs. Blue. Not only does he take an entire pistol clip to the throat at one point, but after that he seems more unstoppable than ever. This most likely being because of Sigma's control over him after said incident. After his defection, he goes on a virtually unstoppable rampage in search for Freelancer AI, and nothing short of being dragged off a cliff by a Warthog into a freezing ocean seems to be able to stop him.
The second appearance of Amazo in Justice League Unlimited falls squarely into this trope. The android, having absorbed untold amounts of power, charges through the entire Green Lantern Corps and the entire extended roster of the Justice League to get to Lex Luthor. It even moved a planet out of its way without destroying it and later bringing it back with little more than a thought. That planet was OA, the HQ of the Guardians of the Universe themselves.
He was almost as bad during his debut. He was able to duplicate and mix all the powers of the original Justice League and was only stopped when someone convinced him to 'look for knowledge' somewhere other than on Earth. Guess that came back to bite the JL HARD.
The Annihilator, an Expy of Marvel Comics' Destroyer (mentioned above), was virtually unstoppable, as it drew power from conflict itself (and thus any attacks on it only strengthened it). Fortunately, this meant you could beat it by not fighting it.
The second appearance of Solomon Grundy. Dr. Fate, Green Lantern, Superman, and even Amazo could not take him down. Repeat, Amazo could not take him down.note Grundy was being empowered by 'chaos energy' and Amazo was a source of it. He was simply making Grundy stronger.
Vilgax, from Ben 10. Oddly enough, it takes a while for Villain Decay to set in, which it finally does in the Made-for-TV Movie... and even after that he can't be stopped permanently, just flung into the depths of space with fingers crossed. At the end of season two, he was in the Null Void, and how he managed to get back from Another Dimension was never addressed. A Time Travel episode at the start of season three showed him dead and in pieces, but he was quickly revived.
Ben 10: Alien Force shows that Vilgax's power goes even farther than that. He defeats ten of the galaxy's most powerful warriors, gets hurled into space (again), sinks to the bottom of the ocean after being caught in his ship's explosion, and if the synopsis from Ben 10: Ultimate Alien's series finale is anything to go by, he survives an encounter from an Eldritch Abomination.
Not only did he survive defying it, he took its power when it was otherwise occupied.
Similarly, Unicron from Transformers: The Movie. A giant monster planet that eats whatever's in his path, and completely impervious to any sort of conventional weaponry. DETONATING A MOON inside his maw didn't even leave a dent, and the combined arsenal of an entire planet of robots that transform into war machines simply irritated him. Lucky for everyone that the good guys had a spare Amulet of Concentrated Awesome lying around... even then, its head remained and continued to cause them trouble.
Yono in the episode "Oh No! Yono!". ("What part of "Yono the Destroyer" confuses you?!"). He swatted Kim and Yori away with ease, and turned Kim, Sensei and Rufus into stone, destroying everything in the process. Left because couldn't hit Hana, who kept dancing all over the place. Ron unfortunately was held at bay by monkey ninjas.
Ron in the last episode, when he throws Warmonga and Warhok into their own spaceship blowing it up.
Savage Opress from Star Wars: The Clone Wars. No jedi is a match for him in single combat and even multipe jedi with clone trooper back up could steer him in another direction. This changes when Darth Maul revives. The elder brother forecefully lays down the Rule of Two on the younger and after serving as The Apprentice for a time he is killed by Darth Sideous with little difficulty.
Combustion Man comes in a close second to Avatar State Aang. He relentlessly pursues the Gaang throughout Book 3 and shrugs off everything they throw at him. They don't even bother trying to fight him most of the time and instead just run, since it's pointless to try and outmatch him. When he finally is beaten for good, it's only because Sokka caused his own powers to turn against him and blow him up.
Amon from The Legend of Korra. He pushed through Tarrlok's bloodbending with only a moment's visible difficulty, and a lightning bolt to the chest only stunned him. It is later revealed that Amon is a master bloodbender himself, quite possibly the most powerful who ever lived, and he withstood Tarrlok's assault by bloodbending himself, and he may have used a similar technique to survive the lightning bolt.
Jonny Quest has Dr. Zin's robot spy. Dr. Zin brags to Dr. Quest and Race Bannon all about his new machine since they won't be able to stop it leaving. The heroes immediately learned that Zin is not bluffing as they desperately try to bring down the spidery robot with everything on the army base from rifles to tanks, but nothing does more than barely slow it before Dr. Quest shoots it out of the sky with his Para-Power Raygun.
The Juggernaut has appeared in various animated Marvel Universe series, which have treated him with varying levels of respect. The 90's X-Men is perhaps the most respectful; Juggernaut gets thrown into the sea by Gladiator one time, but is otherwise treated as truly unstoppable. The early 2000s X-Men: Evolution similarly treats Juggernaut as one of the most dangerous beings the X-men can face. In Wolverine and the X-Men, though, Juggy has been severely worfed and is frequently knocked out and thrown around to show how strong the real villain of the week is.
However, his first animated appearance was actually way back in Spider-Man and His Amazing Friends, believe it or not (in an episode where the XMen also guest starred), and in that version, he was arguably presented even better than Wolverine. (Who was given an Australian accent for some strange reason.) Much like in the comics, he was virtually unbeatable even by the combined efforts of the team and the three protagonists, and could only be stopped by Xavier's psychic abilities once his helmet was yanked off.
The Iron Giant is designed as a nigh-indestructible engine of destruction. Gunfire, tank shells, getting smacked by a train, and even taking a nuke to the face aren't enough to put him down.
Injun Joe the Superchief from and old Merrie Melodies episode called "Wagon Heels".He just marches onward, and he is not hindered by any obstacles, such as trees (he walks just through them, chestfirst), rivers (he submerges by one shore, only to instantly emerge by the other) and grizzly bears (he roars and them and reduces them to their cub state
The Republic P-47 Thunderbolt was nicknamed Juggernaut by their pilots. The plane looked very clumsy and ungainly at first sight, and the pilots thought they were being sacrificed to fly suicide missions in those planes. When the true nature of the plane became apparent, the name stuck - only now it was the Germans and Japanese who were to face the juggernaut when they went up against the P-47. The name was then shortened affectionately to Jug, as the fuselage shape resembled a milk jug.
The next US Thunderbolt, the Fairchild-Republic A-10 Thunderbolt II, is quite similar. Extremely slow, extremely ugly, and completely indestructible (the thing has flown missing an entire wing and an entire engine), and is capable of raining down bullets and ordnance on any ground target. Like its WWII-era granddady, it has an unrelated, commonly-used nickname ("Warthog") that reflects its appearance and its unstoppability (seriously guys: if you ever find yourself in the path of an actual warthog or other wild pig, get out of its way as fast as you can).
The original Juggernauts, of course. Hindu temple cars that reputedly tended to crush devotees in their path by accident, though first accounts mistook these accidents for human sacrifices.
The word is derived from the Hindu Deity Jagannath, an Avatar Form of Vishnu.
A Greek phalanx was a ten-thousand-or-so men. It just kept marching until it trampled everyone in its way. At least until they met Ancient Rome. The phalanx would have trampled even the Romans, had the Romans tried frontal assault. Too bad that the Romans weren't stupid enough to charge a phalanx from the front: their standard tactics were to either slow it down with a smaller phalanx while most of their army defeated what units covered its vulnerable flanks and attacked there until it lost cohesion, or, when the enemy commander was stupid enough to not cover those vulnerable flanks, to lure it on rough terrain, wait for it to charge and lose cohesion and then attack with a crapload of javelins to break it down, at which point the Romans would simply march in close formation. Both tactics ended with Death by Irony: the former caused the phalanx to be trampled by the Roman phalanx supposed to hold it down, and the latter ended with the broken up phalanx trampled by the Romans advancing in compact formations.
The first tanks are a downplaying of this trope; Indeed, nothing the terrified Germans themselves could hurl at the Mark Is were able to phase them in the slightest during the Battle of Flers-Courcelette, but many of them were bogged down and stuck in the very terrain they were designed to navigate through.
Main Battle Tanks, such as the American M1 Abrams tank. The Abrams itself uses complex composite armour that can be augmented by reactive armour and depleted uranium 'strike plates', making it extremely durable but still far from truly invincible; many have been disabled or destroyed by ambushes, improvised explosives, and unfortunately, a few counts of friendly fire. Still, in most situations — and as far as old Soviet-era tanks are concerned — the Abrams and its kin are indeed Juggernauts.
A rare incident occurred in San Deigo where a madman stole an M60A3 Patton and started to drive it all over the local town. Nobody could do anything about it, as the thing rolled over cars, barricades and such without slowing down, and shrugged off anything the police had. The police were in the process of requesting aid from the local military to destroy it (an idea no one was happy with, given it would be difficult to limit collateral damage), but then the tank got stuck on a highway divider, allowing a couple of daring cops to yank the hatch open and shoot the hijacker down.
Something of the sort happened at Arras in 1940, when a detachment of British Matilda tanks rolled right over German anti-tank guns and Panzer I Is, slowly but quite unstoppably until Rommel finally managed to get some 88s (meant to be there as anti-aircraft guns) and heavier artillery in position to shell them. Rommel supposedly thought there had been hundred of tanks in the attack - the actual number of these were 74, and of these, only 16 were equipped with anything bigger than a machine-gun.
The Matilda was the only tank which was in front-line service from the beginning of the war to the very end. It gained the nickname Queen of the Desert in Africa as it completely outclassed any Axis tanks, and Queen of the Jungle at Pacific, as no Japanese tank was match to it. The only ways to destroy it were anti-tank mines or 88 mm anti-aircraft gun.
Both the Panzer III and Panzer IV were extremely poorly armored even for the standards of the time. The Panzer IV was never designed to engage enemy tanks, but even the Panzer III (which was) had extreme difficulty fighting heavier tank designs. Even the French medium tank, the S-35, was almost completely invincible to the Panzer III, requiring a near perfect 90 degree shot to the side from within 50 meters for a kill. Then they went to Russia without upgrading and faced the T-34, the best tank in the world at the time. The T-34 was completely invincible to the German's standard 37mm anti-tank gun and almost completely invincible even to their upgunned 50mm gun while having no issues killing the German tanks. Just to be insulting it was also faster.
The KV-2, armed with a monstrous turret housing a 152 mm howitzer and thicker armour then even the T-34, was able to destroy entire divisions of lesser tanks and dealt with anti-tank guns by running over them. A German report read:
Our companies opened fire from 700 metres. We got closer and closer... soon we were only 50-100 metres from each other. A fantastic engagement opened up - without any German progress. The Soviet tanks continued their advance and our AP projectiles simply bounced off. The soviet tanks withstood point-blank fire from both our 50mm and 75mm guns. A KV-2 was hit more than 70 times and not a single round penetrated. A very few soviet tanks were immobilized and eventually destroyed as we managed to shoot off their tracks, brought up artillery to hammer them at close range and then attacked them on foot with satchel charges.
While not exactly the same thing, Toshiba sold a VCR that once you set the time to record a show, and it started recording, absolutely nothing would stop its completion. The stop button is ignored. The remote control is ignored. Even if you unplugged the VCR for some time and plugged it back in as soon as it was reconnected to power, it would resume recording. The only way you could stop a timed recording before the time ran out was to unplug the machine and plug it back in while holding down the stop button. It was more tenacious than the Postal Service: neither rain, nor snow, nor disconnection of electricity would prevent this courier (of video tape) from the swift (or at least as long as the time period was) completion of its appointed rounds (and rounds, and rounds...).
The rhino is usually a Gentle Giant, but if you piss it off...lets just say that stopping it from impaling you with its horn is easier said than done.
Two other members of the "Big 5", the elephant and the Cape buffalo are both notorious among big game hunters for being nearly unstoppable if not put down immediately.
Even worse are hippopotamuses, which kill more people per year than all of the above put together.
