In general, a battle in pretty much any RPG where your level is WAY over or under the opponent's is like this.
This often happens when the player goes up against what they consider That One Boss.
Age of Empires, oh man. If done it right, you can create a massive curbstomp battle. Watch an army of archers destroying a oncoming attack of swordsmen just because they're behind a wall. Some units in the series can do massive damage without effort at all, like the Persian War Elephants from the second game(except against anti-cavalry units). The opposite may happen, as an example the Russian Strelets from the third game. It doesn't matter if it's 100 units since they're fighting against 20 cannons, they will die without scratching them (Strelets have 7 of ranged attack without upgrades and cannons have 0.75 of ranged attack resistance).
Quite possible to pull off in the Total War series. Gathering an elite army and using proper tactics can result in armies losing fewer than ten soldiers while slaughtering thousands.
Taken to the extreme in the Empire: Total War and Napoleon: Total War games, where artillery can make short work of an enemy army in a few minutes, especially if they happen to get close enough for the artillery to be turned into giant shotguns. Also, a massed cavalry charge may seem like a good idea, except when they're charging line infantry who can quickly form a square, which is the equivalent of them running into a pike wall (which can also happen). The same thing can be done in "The Fall of the Samurai" DLC for Total War: Shogun 2. While artillery in this game has limited ammo (unlike Empire and Napoleon), it also has a far greater range and fires exploding ammo by default. You can massacre an entire army before it even gets close to threaten you, especially if you have naval support. Oh, and if you also happen to have Gatling guns supporting your artillery... In the same game/DLC, any naval battle involving an ironclad going up against wooden ships is usually fairly short and one-sided, since it doesn't take much to set a wooden ship on fire with exploding ammo, while that same ammo does little against an armored hull.
Medieval II: Total War has the Mongols. Oh God, the Mongols. You could be having a pleasant day wiping the floor with every nation on the hardest difficulty when a Mongol army containing thousands to tens of thousands each lead by a general with 8 to 10 stars (10 is the highest in the game) with a rare 7. They move in a way that they can always provide back-up for other battalions of their units despite the fact they can't field more than one battalion (if a platoon dies or flees the map, a platoon from the nearby battalion can march in and take its place) and that they don't NEED back-up. You will have thousands of horse mounted archers who will spread out on the battle field and close like a noose and they will "circle and shoot". If you get too close, they flee while still firing. Following them can get you easily surrounded. Those heavy armored knights you trained and have 5+ experience and that general you have who's never lost? Useless. The only thing you can do is wait it out. The Mongols will siege cities, but they won't take them. The sieges will ruin your economy and their presence will change the whole political climate. Eventually, not quite like in real life, the Mongols take one city and settle down to become farmers. Oh and God help you if your campaign leads right to the city they decided to take. Russia, the western shores of the Mediterranean, Saudi Arabi, and Northern Africa are so hard to navigate and have so few cities that you will have to kill those tens of thousands of soldiers to move on. Or you could just give up.
Pretty much the only way to even come close to leveling the playing field (you'll still have to match their ridiculous numbers, but it's a start) is to throw dozens of assassins at their generals and hope that after the first ten or twelve get killed on mission, one will get lucky and eliminate a general. And there's typically five or ten armies that show up when the Mongols first arrive. Even if you manage to eliminate most of their generals, you'll still wind up throwing tens of thousands of men into a meat grinder against them. If you're fighting on two fronts, you might just want to put both of those on hold and throw everything you have against the Mongols.
Castles. Fight the Mongols from behind walls with lots of archers that can lay stakes (If you are English, French, Byzantines or any other with stakes), or with pikemen covering the gate. NEVER, EVER fight the Mongols in the open. In fact, if you have a faction with great heavy infantry like Denmark or Scotland, by fighting in this manner and only in this manner, you can turn the curbstomp on them.
The final boss battle in The Legend of Zelda: Majora's Mask can be this, if you have the Fierce Diety mask. In fact, every boss battle in the game is this when the player uses the Fierce Diety mask. That is the reason why the Fierce Diety mask can only be used during boss battles. (Except via an unsurprisingly frequently exploited Good Bad Bug.)
One of the absolute joys of the Yakuza series is how you can turn every random encounter into this. In fact, according to tropers, Kazuma Kiryu is curb stomping personified!
In PokémonGold, Silver, Crystal, and their remakes, Lance makes one of his Dragonite Hyper Beam a man at point blank range, and apparently full force. ...Ouch. He survives, though. And yet Lance can't Hyper Beam a few doors for you.
Whitney can also become a curb stomp battle if you don't get rid of her Miltank fast enough before it starts using Rollout.
Brock was this to many first-timers in Pokémon Red and Blue, where he has a type advantage (defensively) against nearly all of the Pokémon you can catch up to that point. The battle can be very difficult if one chose Charmander.
Even more so in Yellow, due to your starter being Pikachu, and again, most of the Pokémon you can find at that point don't have moves effective against Brock. The only way you can actually have an advantage is if you catch a Nidoran or Mankey, which learn a fighting type move after some Level Grinding. Evolving Caterpie/Metapod into Butterfree allows it to learn Confusion, which can do decent neutral damage, but Butterfree is quite weak to Rock-type moves.
Evolve Weedle/Kakuna into Beedrill and allows it to use Twin Needle and Pin Missile. They also do neutral damage to Brock's Pokémon, but due to Early Installment Weirdness, Bug-Type attacks are Super-Effective against Poison-Type Pokémon, effectively making Beedrill a Disc One Nuke.
It's possible to skip around certain trainers when going through the game in, and when traveling back through those areas, sometimes a player will forget which trainers they've jumped around. When they see you and challenge you, it sometimes results in a battle where you have a Level 85 Charizard against their Level 6 Pidgey.
Hell, it's possible to do this to Youngster Joey. Who's top percentage now?!
Even moreso in the Generation V games, where Pokémon Breeders will always engage with you in battle again and again every time you leave and come back to the area they're in. Not bad when your team is near their level, since they outright ask you to fight them again if you want to do some Level Grinding, but ridiculous once it's your level 70+ Olympus Mons against their level 18 scrubs...
Now you've probably heard of the FEAR strategy. You may have heard of the SABER strategy, but it's entirely possible to sweep a team of legendaries with a Smeargle and Magikarp.
Anyone can curb stomp the Elite Four of most games with Level 100 Pokémon traded from another game. Emerald, in particular, has Rayquaza, who is accessible at Level 70 before the Elite Four and can take them all out solo with a few healing items between fights. This backfires when you reach Glacia and Wallace, because Rayquaza is a Dragon Pokémon and they both are Ice trainers. Or at least it would, if Rayquaza wasn't a mascot legendary Pokémon and couldn't OHKO anything they put out.
Beating the game is a fair accomplishment for any gamer, and perhaps easy for some, given the resources that are handed out to the player during the game. However, practically nothing other than the facilities that require you to EV train your Pokemon can stand against an EV trained team. Using a level 100 metagame party filled with strategies designed to butt heads with the best-of-the-best is more than a curb stomp battle for any normal in-game trainer.
In Pokemon Xand Y, if you're playing X, you will get access to Xerneas, who is a pure fairy type. And since the final boss, Lysandre's team is mostly weak to fairy, he will become an absolute joke.
And in Omega Ruby Wallace can become this, due to the game giving you a Groudon and a red orb just before his gymnote giving Groudon the red orb allows it to undergo Primal Reversion, which causes it's ability to change to Desolate Land, causing all water-type attacks to not work, and guess what Pokemon type Wallace specializes in?
In Heavy Rain any of the fights can become this, but one stands out above the rest.
Norman VS Mad Jack, Round 2. As Seen Here (1:30) You can get all the commands right, and poor Jayden still gets his ass handed to him on a silver platter, only surviving by pure luck.
This seems to happen a lot to poor ol' Ragna in BlazBlue against Hazama / Terumi. Every single time he goes against him in the story, he almost always ends up sliced up and on the ground. Even when Ragna activates his Azure Grimoire / is in Unlimited mode which is pretty much BlazBlue's idea of God mode, Hazama can still win effortlessly against him according to the story. Even if you play the Arcade mode as Ragna and beat Hazama at the end, perfect him, AND Astral Finish him, the following cutscene just has him 'thanking' you for the "warm up". The worst part? Hazama himself has an Unlimited mode, made even stronger with his Nox Nyctores, Ouroboros.
Although you may be happy to hear that this gets turned on Hazama in the Wheel of Fortune Drama CD. An extremely pissed Haku-men at 15% of this power appears and takes him on. Even with the help of Ignis, Hazama is still left crying out for help by the end of it. Crowning Moment of Awesome doesn't come close to describe.
If you're playing story mode and your character encounters Relius Clover by themselves, chances are you're not coming out of it okay unless your character's one of the Six Heroes, Valkenhayn in particular.
Ragna: Guah! Kagura: C'mon, Ragna the Bloodedge. Just tell me the truth, you gave yourself the Grim Reaper nickname, right? Ragna: Don't underestimate me, prick. Kagura: I've clearly overestimated you. This is going to ruin my day.
Azrael makes every fight he gets into one of these, and that's when he's holding back. Pretty much every fight in Arcade or Story Mode involving him, even if you're playing against him, ends with him casually cracking his neck while the opponent is desperately trying to find a way to escape. Even the likes of Hakumen, Kagura, and Ragna consider him a monster. In fact, the only times he's ever been "beaten" were do to outside interference, usually by the hand of Kokonoe.
In BioShock, Andrew Ryan initiates sort of a forced, suicidal Curbstomp Battle by uttering that fun little hypnotic phrase...
In Dragon Quest IX, once your main character collects 7 Fyggs, there is a brief battle with your superior, if you can call "you literally can't even draw your sword, while he beats you to a pulp" a battle. This overlaps with Hopeless Boss Fight. Although, in this case, it is clearly Justified since Celestrians must obey and cannot attack their superiors
A similar thing happens in Metroid: Fusion, where Samus is curbstomped by an Omega Metroid due to her lack of an Ice Beam, but the SA-X "sacrifices" itself to save her and she regains the Ice Beam as a result.
Toward the end of Metroid Zero Mission, Samus is stripped of her Powered Armor and has to flee from Space Pirates that can knock off a full tank with every hit. Then she gets a new suit and it's the Pirates who get the curbstomping.
In Heavenly Sword after Nariko ascends to godhood a battle ensues in which she eradicates an entire army without being touched. A close examination reveals that she even evaporates people via proximity, without attacking at all.
If an intrepid player maxes out Iji's Tasen Handling and nearly maxes her Cracking skills, she can put together a Nuke before the end of Sector 5 (4 if you're really dedicated). Rather than pour shotgun shells into Asha's face, all she has to do is pull out this bad boy, wait for him to fully materialize onscreen, and pull the trigger once. Unfortunately, when he comes backhe can dodge those, too.
Asha: Wh- how in the- how did you get a NUKE!? HHH! I'LL GET YOU FOR THIS, HUMAN!
In the game Breakdown, when Derrick Cole first encounters Solus in a pitched battle, Solus is vastly more powerful than him, and Failure Is the Only Option. But, it was pretty much All Just a Dream, and when he meets Solus again, it's a more or less even battle.
In Descent: FreeSpace, almost every appearance of the enemy command ship Lucifer leads to a Curb-Stomp Battle. The most powerful human-built warships in existence, including the ship the player is based on, the GTD Galatea, get ripped to shreds in about five seconds whenever they try to make a stand against the Lucifer.
Half-Life 2 contains one of the worst examples ever. The Universal Union, informally known as the Combine, invaded Earth in the game's backstory. The war became known as the Seven Hour War, and, well... we lost.
Episode 2: three vortigaunts vs. approximately a hundred antlions. The antlions lose. Badly.
Gordon Freeman, theoretical physicist, vs. a dimension-spanning army of slavemasters. Those bastards already had no chance... and then his gravity gun gets supercharged.
Kuzuki Vs Saber in Fate/stay night is a crushing defeat for Saber, who has NO idea what is going on while being effortlessly pummeled and having her neck ripped apart before being slammed into a wall at about 120 miles an hour. A little later in the route, Berserker is utterly crushed by Gilgamesh, though it's noted that if he HAD managed to close the gap between them, he would have won instantly. He almost does manage to do it except Gilgamesh cheats and has Enkidu, chains for snaring divine opponents such as Berserker and Lancer and even Rider (both Medusa andIskander).
In Super Scribblenauts, pitting Death against virtually anyone causes their death with a single touch. This includes God. Also, creating a Black Hole will destroy everything within seconds.
In [PROTOTYPE], you can have literal curb stomp battles with human enemies. There is a move aptly called Curb Stomp, which will surely kill the poor bastard beneath your heel. One of the consume animations does it automatically.
Ace Combat 04 has quite a few battles like this early on in lore, such as the destruction of the "Invincible" Aegir Fleet in harbor. It seems that ISAF was rather good at choosing its counterattacks against Erusea, both for tactical and strategic reasons — namely, keeping morale up while still influencing the overall outcome of the war.
There's a fight bewteen Machias, Jusis and Rean against Instructor Sara who was way above their level and Rean against Victor S. Arseid in later chapters to establish power level. If one of your opponents is an A-Rank Bracer and and the other is one of the greatest swordsman in the country, this should be expected.
The Panzer Soldats utterly and completely wreck the First Armored Division (the Imperial Guards no less), destroying even the most advanced of tanks with a single blow each.
Crow inflicts one of these on Rean while both are operating their respective Divine Knights, with Crow pointing out that he's had three years to learn how to pilot his machine while Rean has only had a few minutes.
If you carry over your levels and equipment on New Game Plus, you can easily devastate Sara, even in Nightmare mode, by flashing her with Rean, Machias and Jusis's S-Breaks before she can even get a turn. So the game cheats by making it so that you can only reduce her HP to 1 and then she flashes your party with own S-Break for 49,999 damage each to annihilate them. If any of them had any sort of guard status up to protect against it, she'll just do it again.
Similarly, you can have Rean hold his own against Victor for a while if you keep healing, but eventually he will hit him for 49,999 damage and it's over.
At the end of the first Act of Cold Steel II, all of the most major players of allied forces of the Noble Alliance descend upon Ymir. Obviously things do not go well for our intrepid heroes. It ends with Rean agreeing to come the Noble Alliance's flagship airship for a meeting with the Noble Alliance's leader, Duke Cayenne.
On lower difficulties, it is possible to create a highly amusing one on Noveria, by killing Kaira Stirling and Alestia Iallis within seconds of their respective villainous monologues:
Kaira Stirling: I don't need a gun to tear you to pieces. *BLAM
Alestia Iallis: I was ordered to eliminate you, should the opportunity arise, and here you are, trapped in this lab. Weapons free! *BLAM
Like most RPG and third person shooter video games, pretty much every mission will end with over a hundred enemies dead and no casualties for the heroes. There are a few exceptions, though, where the team either gets help from other NPC allies (who die) or can get potentially Killed Off for Real.
A particularly amusing one is the optional Garrus mission in which you track down Dr. Saleon. Once you find him, if you convince Garrus not to kill him (or just don't bring Garrus along), Dr. Saleon will try to kill you anyway. He dies in one hit, making him one of the weakest, if not the weakest enemy in the game.
Two examples from Mass Effect 2: The Normandy, despite representing the cutting edge of Alliance tech and having gotten the killing blow on Sovereign, gets utterly eaten by the Collector cruiser. Upgrading the Normandy SR2's weaponry lets Joker take an eye for an eye.
Something could also be said for the fact that one of those upgrades is a weapon system specifically reverse engineered from Sovereign's 1HKO cannon from the first game that unsurprisingly, lets you one shot the collector cruiser.
The entire suicide mission could become this if you make the right decisions. Shepard will have wiped out every one of the Collectors and lost no people in the process.
An amusing one where Niftu Cal, a.k.a. the Biotic God, a volus who is high as a kite goes to fight Captain Wasea, leader of a group of Eclipse mercenaries (all of whom murder to join) and former asari commando, who are widely regarded as being some of the greatest fighters in the galaxy. He throws a little biotic ball at her that just bounces off the end of her nose, mildly annoying her at best. She proceeds to use her biotics to one-shot him across the half the room.
Speaking of asari commandos, there's the War Assets entry for the Serrice Guard, which tells of how a Blood Pack mercenary gang which crash-landed on a planet took over a hundred casualties from traps, ambushes and night assaults over the course of nine days. When the Blood Pack finally gave up and surrendered, they did so to the asari commandos who were hunting them. Allfiveof them.
Also in Mass Effect 3: Shepard, EDI, and another squadmate (code named "Entry Team") vs. the Cerberus Base and everyone on it. Including Kai Leng again at the end.
Seems to have happened when the Krogans were exposed to the advanced technology of other races. The Salarians were only able to stop them with the Genophage. Anytime the end of the Genophage is brought up there's always a few people showing their fear of the Krogans coming back.
Much of the war in Mass Effect 3 counts. While small victories are made here and there, everything is just a holding action until the Crucible is completed. The only two species that really put up a hard fight against the Reapers are the turians and krogan, and even they suffer massive casualties and eventually are forced to pull back and leave their homeworlds behind.
The final battle of Mass Effect 3 is a mostly hopeless slugging match between the Reapers and the combined fleets of the galaxy... until Shepard reaches the Crucible. If s/he activates the "Destroy" sequence, every single Reaper instantly drops dead.
In the Citadel DLC, your allies...do not think highly of CAT6 troops, put it that way. Much of the chatter you hear from said troops consists of them realising another way in which they're outmatched.
Tali: This is almost unfair! Should we give them a chance?
Even their boss (with good reason) thinks they're outmatched.
Merc: What did s/he mean by "Slow him/her down?" We're allowed to kill Shepard if we have to, right?
Merc Lieutenant: s/he said "slow him/her down" because s/he thinks we're cannon fodder!
Merc: Oh. Well... shit.
Metal Gear Solid 3: Snake Eater has a badass Naked Snake every time you control him, knocking out guards with his CQC skills, only to be completely curbstomped by the Boss every time he has to do hand-to-hand with her. The very first battle ends with Boss breaking his attempt to grab her, breaking his arm, and hurling the poor sod off the bridge they're fighting on. Snake gets a bit better with each subsequent fight, with the last one having him even managing to get her on one knee before she knocks him flat on his ass. Slight aversion, as the player hardly expects there to be a great big confrontation with her. That is saved for the last boss fight, where he finally manages to defeat his mentor... not that he really wanted to.
Subverted in Metal Gear Solid 4: Guns of the Patriots, when Meryl's entire Task Force surrounds Ocelot's single patrol boat to arrest him. Outgunned by 1 to 100, with several patrol boats and helicopters circling him, Ocelot doesn't think of surrendering, so Meryl orders to open fire. But because Ocelot already got control of the Doomsday device, absolutely nothing happens and the attackers' entire equipment array shuts down. Cut off from their emotion control system, the soldiers break down with shell shock and then Ocelot turns everything into a Curb-Stomp Battle in his own favor.
In a cutscene in Command & Conquer: Generals a battalion of US Crusader tank face off against GLA Scorpion tanks, the result all the GLA tanks get obliterated while the US tanks suffer 0 casualties. Then another column of GLA tanks come in only to be bombarded by Raptors.
This was actually based off a real life example where a handful of US Abrams tanks were squaring off aginst Iraqui tanks in the Gulf War with a similar result.
In Baldur's Gate II, battles involving Jon Irenicus can be summed up by whether or not the main character is fighting against him during the battle. If not, well...
In the Final Fantasy Tactics remake War of the Lions, there is a new battle where you play as Delita and you are required to protect Ovelia from a Northern Sky ambush. The enemy is a Knight, Archer, and Black Mage, all level 8. You are level 25 and have special sword skills that deal high damage at long range in an instant, and an ally that can cast all status buffs in one spell. Do the math.
Certain parts of Dragon Age: Origins pit you against "Grunt" versions of the Darkspawn you have been fighting throughout the game. Unless you haven't been improving your characters' stats at all during the entire game for some reason, everyone in your party will be able to kill them with one hit. Actually, by that point in the game, any enemy that isn't "Elite" or "Boss" rank will probably be utterly trivial to defeat.
The reason for this is, the Darkspawn are called "The Darkspawn Horde" for a reason. They have simply massive numbers, and killing a few dozen is a trivial victory when they have tens of thousands. They can outnumber you, to the point you start getting tired, start running out of poultices/healing spells, and/or the healer can get ganged up on, if there are simply too many darkspawn around you. That's the whole tactic; they have an army. You only have a few heroes and a few guards to fight them with. Most of the guards die, leaving just your heroes against their army, a few of their elites, and a huge freaking dragon.
The final battle of Fallout 3. On one side, we have the Enclave with an advantage in numbers and equipment. On the other side, we have the Brotherhood of Steel, having an advantage in training. Now this will be a lively bat- oh wait, the Brotherhood has a 200-year old, radically anti-communist Humongous Mecha, which also conveniently believes that the Enclave are communists.
In Fallout: New Vegas, if the Courier manages to recruit all of the major factions to their cause (only possible in the NCR or Wild Card endings) and fortify all NCR positions, the final battle against the Legion becomes this.
If you follow House's path, then the upgraded Securitrons proceed to curbstomp the Legion at the Fort. Heavily armoured robots toting rocket launchers, grenade throwers, Gatling lasers and machine guns versus hundreds of squishy legionaries.
Boone's personal quest involves stopping an entire Legion Raiding Party's attempt to attack a small NCR garrison containing civilians. The swiftness with which Boone and the Courier turned the tables is mentioned in the news by Mr. New Vegas;
Mr. New Vegas: According to one witness, "God sent us two angels, and at least one of them had a .308 caliber flaming sword of justice with a telescopic sight."
Honest Hearts, if you want to let the final boss die with dignity, he'll gear himself up and charge you with his tribe. He's tough, sure, but you have JoshuaGraham on your side. You can literally just stay back and watch him massacre the entire tribe on his own.
Predecessor Fallout 2's final battle can happen in a number of ways. The most curb-stompish involves the main character turning all the base's defenses against the boss, then engaging him along with his party. The boss will find himself against several hard-hitting turrets (who might even kill him all by themselves with enough lucky rolls), the party's guns and the player's own. He usually dies without even causing enough damage to require stimpaks.
The Minutemen of Fallout 4 got the taste of one in the Quincy Massacre, where they were betrayed from within and led into a killzone by the Gunners. Only one Minutemen survived: Preston. If you help them rebuild, they can end up inflicting one on the Brotherhood of Steel, with the help of some pre-war heavy artillery.
Speaking of the Brotherhood of Steel, if you go for their ending, it turns out they've rebuilt Liberty Prime in the 10 years since his destruction in Broken Steel, and against the Institute's Synths, they fare even worse than the Enclave did against the big guy back in 3. At one point on his way to destroy the Institute, Liberty Prime encounters a Super Mutant Behemoth (which would be a tough fight for your character normally) and Liberty Prime just picks the abomination up, crushes it in his hands and casually tosses it aside like trash.
Though character's don't comment on it, the battle of Bunker Hill can potentially be this for the Brotherhood of Steel, as the Railroad's Heavies tend to be armed with Gauss rifles and Railway rifles which can punch through Powered Armor with no trouble, while their armoured coats tend to have the energy protection to withstand the Brotherhood's laser weaponry.
The first battle of MOTHER 3 pits a Mole Cricket against your two low-level characters. It's easy, albeit not quite Curb Stomp easy. Later in the game, you find the Mole Cricket again, who challenges your higher-leveled team of four. The Mole Cricket has a higher Speed stat the second time, but all that means is that he gets to hit you once for Scratch Damage; all his other stats are the same, so he's unlikely to get even a second hit.
Some of the harder boss fights in Earthbound become pretty one sided if you use a multi-bottle rocket.
Also in Earthbound, if you're a lot stronger than an enemy, you just skip the battle phase and instantly win.
Cubia's first appearance in the original .hack// games is this. Kite manages to beat Skeith, who melts into a puddle of goo. Earthquakes start happening, weird, blue tree-like things start sprouting up in two lines heading directly for Kite, the goo begins bubbling furiously, and then there's a gigantic explosion. When the dust settles, Cubia's floating in the sky, completely dwarfing Kite. Kite can only numbly look on as Cubia prepares ahuge attack. Cubia then unleashes a literal Mighty Roar that causes inverted colors and sends Kite flying away like a ragdoll. The only reason Kite survived that encounter was because of Helba's interference (again).
In Dot Hack GU, Haseo's first fight with Tri-Edge. Events in order:
Haseo spots Tri-Edge. Using his twin-blades, Haseo unleashes a barrage of attacks while Tri-Edge, with no effort blocks all of them with one hand.
Seeing the attacks having no effect, Haseo jumps back and takes out his broad sword. Charging at Tri-Edge again, unleashes a heavy blow with broad sword, only to be sent HALF WAY across the room from Tri-Edge barely tapping him.
With Haseo crouched down on the floor, amazed at Tri-Edge's power, Tri-Edge slowly walks towards Haseo, withdrawing his twin-blades. With another attempt at getting revenge, Haseo takes out his scythe and upon delivering the blow to Tri-Edge, it is completely shattered by Tri-Edge who doesn't even lift a finger to do it.
Shocked at what just happened, Haseo looks at his hands in horror because his scythe just completely shattered. At the last second, Haseo looks up at Tri-Edge who was still slowly approaching Haseo. Tri-Edge then grabs Haseo's face and unleashes a blast sending Haseo across the room—again.
Haseo could only look on in horror as Tri-Edge charged his attack. Moments later, Tri-Edge unleashed Data Drain, destroying Haseo and reducing him from level 133 to level 1.
The tutorial boss in Demon's Souls is designed to kill you in one hit. If an experienced player manages to beat him against all odds, a huge dragon (one of the final bosses) will punch him to death in a cutscene.
And it's successor, Dark Soulsoh so much . It's entirely possible for a new player to strut into the Asylum Demon's arena completely unaware of the fate that awaits him, due to the fact that the only enemies has has fought to that point were squishy hollows.
And that's just the tutorial.
In Disgaea: Hour of Darkness, the World, defended only by Laharl and his handful of companions, gets besieged by a fleet of millions of human battleships. The bulk of the battle is Laharl destroying all but the capital ship, alone, in a matter of minutes.
Lucien, during the While Guthix Sleeps quest in RuneScape. When you last saw him, he was a hooded stranger asking you to steal an artifact for him, and you had the option of doing so or, after meeting the guardians of said artifact, killing him, and he is extremely weak (level 14, in contrast, most players on that quest would be at least 60+). You learn in While Guthix Sleeps that he has apparently become a lot more powerful, and so assemble a group eight of the world's greatest fighters, a few of which you have gotten to know in previous quests. When Lucien spots you sneaking around in disguise, he attacks you, and the eight teleport in to fight him and save you. Only two survive, and barely escape alive.
Not to mention those two only survived because they didn't directly attack Lucien. They just stood behind and fought some of his troops.
Lucien of all people comes on the receiving end in Rituals of the Mahjarrat when the Dragonkin enter the scene.
All player characters have the potential to do this, they basically have unlimited potential and can end up over a hundred times stronger than the average citizen.
Dragon claws can do this to players and npcs alike, hitting 4 times, quickly, and quite hard.
Made famous for doing this, Sephiroth will kill you on the first move of his battle in Kingdom Hearts II if you are a low level or unprepared.
In fact, if you defeat Sephiroth, you will likely be pummeled to within an inch of your life. Take note of that, because in the following cutscene Sephiroth is casually brushing off his shoulder pauldron, not even tired.
Also, Sephiroth curb stomps Cloud for the majority of their battle in Advent Children, even while not taking the battle that seriously.
Unfortunately for him, Sephiroth has also been on the receiving end of a CSB in the end of Final Fantasy VII: all he can do is attack for 95% of your remaining health (never enough to kill you), and Cloud will terminate him with a single Omnislash.
Any time Knights of the Round are summoned in Final Fantasy VII. The following is a very opt description of its power. It can be found this strategy guide.
BTB: Sometimes, killing your enemies just isn't enough. You want them more than dead. That's where Knights of the Round comes in. It should take no more than 3 of these guys to end the life of just about anything you come into contact with, but that's not enough. Ultimate End subjects your opposition to all 13 of them. It's kind of like those old Mach-3 commercials, actually. You know, with the three blades that each had separate jobs? You see, the first knight appears on the battlefield and kills everything there. The second knight then kills anything foolish enough not to be killed by the first knight. The third knight kills everything again for good measure. The fourth knight kicks the corpses around a little bit and compiles them into a large mound in the middle of the battlefield. The fifth knight sets fire to the mound and performs a strange, ritualistic naked dance around them. The sixth knight roasts some marshmallows over the fire and laughs heartily at the fifth knight. The seventh knight stares blankly at the burning bodies as he pokes and prods at them with a stick. The eighth and ninth knights begin a game of soccer using the disembodied head of one of the flaming corpses as a ball. The tenth knight douses the fire and repeatedly stomps up and down on the charred remains of your enemies. The eleventh knight scrapes up what is left with a spatula and tosses it into a trash can. The twelfth knight tosses the trash can into a compactor, reducing it to a small cube. The thirteenth knight def*** on the cube.
In Crisis Core: Final Fantasy VII any mission labeled "Very Easy" is expected to have Zack able to crush any opposition in five hits or less.
Also from X, in that same sequence, when you fight Sinspawn Gui with Seymour. His entire appearance in the fight is a pure Taste of Power, and you have to actually try to lose in order to not win.
Final Fantasy II starts with one immediately. Get your teeth kicked in by end-game enemies. It will be a long, long time before you can claim revenge; even then it will be hard fought.
In Theatrhythm Final Fantasy, if you have your party equipped with reactive spells and abilities that are triggered by a boss' appearance in the Battle Music Stage that you are playing, it can lead to a curb stomp battle where bosses can be defeated nigh-instantly and are easier to defeat than many of the mooks, funnily enough. This goes double for Theatrhythm Final Fantasy: Curtain Call, which increased the number of skills that were available and included many new and more effective ones than the ones in the first game.
The US Marine's invasion of Qurac in Call Of Duty 4 was this. They utterly steamrolled Khaled Al-Asad's Army and were able to reach the capital city within days, and take the city in hours. Unfortunately for them, Al-Asad had a Plan B.
Taken even further in Modern Warfare 2. As their final act of revenge, Soap and Price tear through hundreds of Gen. Shepherd's Shadow Company troops and eventually kill Shepherd himself. As a testament of just how the two killed everyone so fast...
Oxide: Disciple Nine, your entire rear guard just flatlined!
Disciple Nine: That's impossible, we just-
Gen. Shepherd: It's Price.
The first part of the last level in MW 3. Dozens of guards in suits with pistols against two men In juggernaut suits with belt-fed machine guns.
When you reach the end of the level, you finally get to kill Makarov. The problem is, Price is an unquestionable Badass while there's nothing suggesting Makarov is a skilled hand-to-hand fighter. Once Price manages to actually get his hands on him, he goes down much more pathetically than, say, Shepherd did in MW 2. Makarov's death is more of a brutal execution than a straight-up fight.
In Victoria 2, having an Infamy rating above 25 without an army large enough to take on several great powers at once causes the AI to gang up and initiate one of these on the Player.
In Marathon, Durandal's single corvette is attacked by an alien 'Battle Group' for the purposes of destruction and reverse-engineering. Little did they know that Durandal had so improved the alien's technology that he could fire their weapons at approximately twice their standard range. He still loses, but not before inflicting a massive amount of damage on the Battle Group. He even mentions that the alien's High Command has already changed its curriculum; all generals will now be taught The Humbling of Battle Group Seven at Lh'owon.
The Spider-Man 2 adaptation had this for taking down Mysterio. He clearly charges up three stages of health bar and you go through all of them with one punch to his fishbowl head. (Now THAT is a glass jaw.) Of course, since Mysterio is an unenhanced human being whose super powers are limited to being good with special effects, that he can be owned by someone able to use a car as an impromptu throwing weapon isn't much of a surprise.
Inazuma Eleven: Teikoku match in the first game. Then Gemimi, Epsilon, and Genesis in 2. However, you are the one being stomped, not them. The story some time force you to be stomped even harder with 0-18 or so.
Chrono Trigger can easily have this if you go to Lavos too early. Also, you're supposed to lose the first fight with the Golem. And the fight with Lavos in the Ocean Palace (which has triple the stats of the normal Lavos to ensure that you lose).
And if you go through the game proper (or through New Game Plus) and reach the very first part of the final battle—Lavos' other shell—you fight impressions of nine of the game's bosses that have the same stats as the originals. It would take a lot of effort to lose to most of those fights.
Similar to the New Game+ for Chrono Trigger, the Fighting Your Friends fight as Lynx can be flipped the other way and result in a glitchy cutscene where you're stabbed by a dead enemy.
In the FPS/RPG Strife, most boss fights after The Programmer fall under this trope. Until Spectres erupt from their bodies.
In City of Heroes, it is possible, even easy, to make a character that can do this to huge amounts of enemies, even Archvillains (though that can be more time-consuming to put together). A more apt example occurs in the first mission of Mender Ramiel's story arc. Ramiel hands you a crystal and tells you to observe your future self. The mission is populated by a swath of high-powered echoes of various Hero- and Archvillain class enemies, at full power, any one of them easily a match for a team of players. They never stand a chance (unless you get hit with the bug wherein your Incarnate powers take a minute to activate when you enter the mission. Then it gets reverse back on you)
In AdventureQuest Worlds, your hero and Zhoom spend half of the Sandsea saga finding a Djinn that can help them defeat Tibicenas, the Chaos Lord of that particular storyline. But when the heroes face Tibicenas in the Djinn Realm and the Djinn in question, Saahir, steps forward to throw down with him? Saahir doesn't even last five seconds.
Yggdrasill will likely pull one on you in the Tower of Salvation in Tales of Symphonia. Frequently with one move.
Arguably, the fight before that against Kratos will make your team eat dirt if you are unprepared. Up against Judgement and Level 3 attacks, speed casting, with an injured team from the previous boss battle? The life bottle count will probably rapidly fall, and you haven't even gotten to the Hopeless Boss Fight yet. Funny that if you lose, you won't Game Over, but you're still pitted against the next boss.
The final boss battle in Rune Factory 2 turns into this if you cast Dragon Break as soon as possible, freezing the dragon in place while you wale on him, and repeating the process the moment he Turns Red.
In Baten Kaitos: Eternal Wings and the Lost Ocean, your party comes up against the Empire stooge Fadroh. Who curbstomps who depends upon whether or not Fadroh buffs himself up with the Orb of Magical Offense, which makes him obscenely powerful.
This is how the early months of Jeff Wayne's War Of The Worlds will go, the Martians crushing the humans, with the Martians scout machine alone taking out 3 or 4 armored lorries on its own. This is balanced by the Martians' need to build comm centres, giving mankind time to build up and bring out the big guns.
It is possible to do this in any of the modern wrestling games if skilled enough, taking out your opponent by beating him to within an inch of his life while taking no noticeable damage yourself.
Glass Joe, from Punch-Out!!, can be knocked out in one properly-timed hit to the gut, or several to the jaw, all while he fails to retaliate properly. It is quite amusing.
ZODIAC Virgo delivers a pretty nasty one to the Phoenix in RefleX, killing the pilot. Unfortunatly for Virgo it was revealed in that moment that the Phoenix was an ZODIAC as well, ZODIAC Ophiuchus. Virgo doesn't stand a chance in the following curb stomping.
Then ZODIAC Ophiuchus does the same to the other ten ZODIACs as they arrive...though most of Earth becomes collateral damage in the process.
Common in Galactic Civilizations. Especially if your opponent went for multiple smaller ships, while you're rocking a Nigh Invulnerable battleship. On a less enjoyable hand, the Dread Lords can crush pretty much any planetary population with ten men, and their constructors have more guns than most battleships.
In Everquest and other MMORPG's the nature of the persistent world and the constantly escalating power curve of players and equipment means that formerly top end raid zones become fodder for the more powerful and experienced players. To the point where you can One-Man-Army entire armies and old world gods such as Cazic Thule, Innoruuk, Tunare, etc.
If you've got two or more Ages on your opponent in Rise of Nations, said opponent is not going to enjoy the experience. Tanks and bombers rather neatly trump musketeers, it has to be said.
One of the coolest parts of Bangai-O is that most of the boss battles can be turned into this (for the best results, go ahead and fight Sabu). On the flipside, the harder bosses can do the same for players that aren't used to fighting them.
In EP5, Bernkastel introduces Canon Sue and new furniture to kill Beatrice, further her own plans, and royally screw with the status quo. Eventually, Battler and Beato's furniture decide that they are having none of this. Epic smackdown ensues.
Also, Featherine delivers this straight to Lambdadelta in EP8.
Agni vs. Tyr in Breath of Fire: As Agni, the player's attack does the max allowed damage, while Tyr does pretty much negligible damage. Add that this dragon form merges the whole party into one being, and the whole battle is reduced to hit the attack button repeatedly, healing with items that one time you may get low on health.
For that matter, pretty much any battle where you summon Agni will always becomes this. He isn't called "The Ultimate Power" for nothing.
The Bad End final boss in Breath of Fire IV, you as the Infini Dragon vs. your former party. The character in question has full-life regeneration each round and a technique that reduces the target's Hp to 1.
Anything that crosses Fou-lu's path in IV is also asking for a magnificient curb-stomping. Not for nothing he's the God Emperor.
Getting into a fight with any of the Boss in Mook Clothing in any game with a low-leveled party is practically this. Most notable against Berserker and ArchMage; the former will slaughter anything with his basic melee attack, while the latter will not be happy with just curb-stomping you, but will ressurect the party just to keep doing it ad-infinitum.
Echigoya from Tenchu, an untrained merchant with a slow-loading one-bullet gun and 80 points of life (lowest for a boss). Tenchu: Fatal Shadows also has Tatsukichi, a geisha with almost no Hp, who moves very slowly and after a 5-seconds start-up animation.
In Kirby: Triple Deluxe, the third time you fight Flowery Woods you have the Hypernova ability, allowing you to defeat him by simply inhaling him.
Id from Xenogears: seven years before the beginning of the game proper, Solaris sent him to crush the Nation of Elru: Id did not defeat Elru by himself: he wiped out the whole country. Later, he turns his fury against his former employers, and obliterates the heavily guarded capital of the world's most advanced nation in minutes.
In the same game, there's the fight against Grahf on the Goliath. He's one of the hardest bosses in the game, which is saying something considering that he's on foot battling your party, who are in their gears.
Then there's the final boss, where Fei faces what Miang became after she was absorbed by Deus. Two things to keep in mind: first: Fei is the alter ego of both Id and Grahf, and second Id and Grahf both had numerous psychological issues that actually crippled them. The man who faces what's left of the game's main villain at the end has all the aforementioned characters strengths and the inner peace they sorely lacked: the final battle is pretty much bereft of any challenge or suspense, being basically the video-game equivalent of God-Man versus the Purple Beetle.
Not to mention if you reach the Star Forge and your character is at the highest and on Easy Difficulty, prepare to essentially decimate the legions of Dark Jedi and even the Dark Jedi Masters without a single care in the world.
It's entirely possible to simply be curb-stomping most of the enemies you come across from midway through the game. The latter half of Korriban can be absolutely hilariously one-sided if you've invested in Force Lightning to it's final level, Force Storm, which does absolutely absurd amounts of damage for relatively low amounts of Force points. Entering the Academy after offing the top instructors, you're confronted by a crowd of Sith. The game pauses so you can give orders to all your squadmates, but pragmatic players will take one look at the room, go "yeah, I don't have time for this," and arc-lightning the entire room to death in a way that would make Palpatine jealous. Even Light-side characters.
In Knights of the Old Republic II: The Sith Lords, the protagonist at one point has to take on virtually every bounty hunter in the Jekk'Jekk Tar, single-handedly, in an environment full of gas that is poisonous to the Exile but nobody else present. This may well be before you actually get a lightsaber. It ends with a significantly reduced bounty hunter presence in the Refugee Sector and the Exile going on to virtually singlehandedly maul their way through a secret base under the Jekk'Jekk Tar as well, just to make it as clear as possible how dangerous a Jedi can be.
inFAMOUS 2: After fighting the Beast and Kuo, Cole decides to take a few last shots at the Beast before firing off the RFI. To clarify, he shoots down a 100-foot giant made of lava. Using thunderbolts.
In Doom, the final weapon, the BFG9000, deals 3150 average damage (and, due to 601 dice rolls being done, very little deviation from that). The spider mastermind, in comparison, has 3000 health. Yes, people, the final boss of Doom can be slaughtered in one shot with a weapon you find on the third map of the third episode (keep in mind there's nine maps, the ninth's secret, and it's on every map afterwards save the eighth).
If you win against your opponent four rounds in a row in Divekick, a message appears that says "Fraud Detection Warning". Win the next round, and that message then turns into "Fraud Detected".
Civilization games can become this if you have enough of a technological advantage over your opponent. (e.g. Their crossbowmen against your giant death robot)
Although it's possible for spearmen to destroy a tank in some versions.
One of the trailers for Assassin's Creed III shows a battle during The American Revolution, which seems to be a Curb-Stomp Battle for the redcoats (led by a Templar). Then Connor shows up, "borrows" a horse, gets it shot out from under him, hides behind some rocks as another volley of musket balls head his way, runs out while the troops are reloading, jumps into the ranks, and the slaughter starts. Even the elite Highlanders can't stop him. The fleeing Americans see the commotion and charge back into the fray, helping Connor with some well-placed cannon fire. Connor kills the Templar general (hit him with an arrow and then finishes off with a tomahawk) and disappears. The British are in utter disarray and are quickly routed.
Pokémon Colosseum has this in one part of the game. Rui's grandfather, Myth Trainer Eagun tries to stop a Cipher Elite Peon, resulting in a CPU VS CPU battle. Rui's grandfather sends out his high-leveled Pikachu, while the Cipher Peon sends out a shadow Hitmontop. Note that you can see a purple box, meaning that Hitmontop is a Shadow Pokémon. For all Eagun's expertise, he decides to have Pikachu use the weak Quick Attack repeatedly, ensuring that Hitmontop will defeat him. And then he talks about how fearsome shadow pokemon are. Talk about Narm.
In the sequel, Pokemon XD Galeof Darkness; when you first visit Gateon Port, Thug Zook threatens Michael (player) and his sister with a shadow Zangoose. Mr. Verich's bodyguard then sends out an Alakazam in another CPU VS CPU battle and wipes the floor with it.
Golden Sun has one at the start of the first game to introduce its main antagonists, Saturos and Menardi. Even if you hack the game so that you win, they still beat you and bunny hop away.
It's also what happens to a lot of people the first time they go up against the Dullahan.
In Jedi Knight 2: Jedi Outcast, Desann, a Dark Jedi, encounters Kyle Katarn, a former Jedi whose Force abilities have eroded over the years. Despite his formidable arsenal and training, Kyle does not stand a chance against the power of the Force.
Sleeping Dogs has two, one when you go find Benny in club Bam Bam and chase him through the club dispatching dozens of his mooks, the second when Wei has been tortured to within an inch of his life, including but not limited to have his torso cut with a scalpel, one of his knees attacked with a drill and one or more of his toes broken, and he promptly escapes, brutally kills every enemy in the safe-house before chasing down the big bad and throwing him into a woodchipper.
Playing Nox as a Fire Knight (warrior) one chapter features undead invasion on warriors' stronghold, when Hecuba walks into throne room the Fire Knight's Leader Horrendus challenges her to single combat... Long story short after accepting his invitation to "dance" she oneshots not only him but his elite guards as well.
In Dra Koi the dragon first absolutely flattens the military and then gets the crap kicked out of it by the armored knight right at the beginning. This repeats a few times until the end, when the true climactic fight takes place.
And the level after that. Adam Jensen, about as upgraded as he's going to be, versus dozens of hallucinating and unarmed but augmented people in close quarters. Depending on how you're playing the game, carnage or an incredible (possibly nonlethal) beatdown ensues.
A Good Bad Bug in The Elder Scrolls V: Skyrim allows an infinite loop to power up the capabilities of alchemy and enchanting, allowing equipment to be pumped up to ridiculous levels. While wearing these super-clothes, a single punch can deal out over one billion HP of damage.
The Temple of the Monkey God in the Bloons Tower Defense series can dish these out in a heart beat, especially when maxed sacrafices are given to it. In fact, its well known for its power & awesomeness.
The final mission of X: Reunion has a huge Terran fleet jump into an equally huge Kha'ak fleet, in an epic battle involving thousands of ships. The result? The Terrans lose a few ships, while the Kha'ak take such heavy losses that they are effectively wiped out as a species. Terran ships are apocalyptically powerful, and even after nerfed in subsequent games, they still tend to win battles pretty handily unless badly outnumbered.
The Kha'ak themselves inflict one on the Argon Federation at the Battle of President's End. In a battle scarily reminiscent of Pearl Harbour, several Argon stations and ships are annihilated in a Kha'ak surprise attack, at little cost to the attackers.
World of Warcraft has a few of these battles. Darion Mograine charges the Lich King after LK takes his father's soul. LK barely waves a hand to send him to his knees. On the opposite side, Darion tosses his sword to Big Good Tirion Fordring, who accordingly curb stombs the LK so hard he runs away.
The final battle against the Lich King in Icecrown Citadel has two seperate curb stomp battles from two parties. The first one is done by the LK himself. After reaching 10% health, the Lich King one-shots the entire raid group. He goes on to declare that he could have killed them at any time with no effort, but by letting Tirion (currently frozen in ice) and his champions defeat his greatest creations and reach him, he tricked Tirion into delivering the greatest group of heroes the world has ever known right into his hands, to raise as his person group of undead super-soldiers. The second curb stomp occurs when Tirion calls upon the powers of the Ashbringer, breaking free of his icy prison and shattering Frostmourne. Every single soul the Lich King had ever taken was released from the sword, lifting him up and, essentially, immobilizing. The Lich King is forced to watch helplessly as Tirion and his champions (resurrected by the spirit of Arthas' father), as well as the countless souls, beat on him relentlessly. It's as he says himself "Now I stand, the lion before the lambs...and they do not fear. They cannot fear..."
Apothecary Putress versus EVERYONE at Wrathgate. NO ONE survive his plague attack. Only dragons of life were able to clean it up.
Thrall with the Dragonsoul vs Deathwing. Massive world-breaking dragon vs a tiny (comparatively) orc shaman who is seemingly powerless? The curb stomp IS IN Thrall's favor. All is going well for Deathwing until he notices Thrall holding one of the most powerful weapons ever made. After having his armored plates ripped off, Deathwing get's blasted with the Dragon Soul and plummets into the Maelstrom. The full damage is seen when Deathwing pulls himself back out of the water, now more a abomination of fire and scales than anything resembling a dragon. Thrall demonstrates the weapons power again, blasting the weakened Earthwarder until he literally disintegrates. The best part is that Deathwing had a hand in creating the Dragonsoul, so he knew all too well just how powerful it was.
Thrall gets another one in Warlords of Draenor. His final battle with Garrosh, former Warchief of the Horde, Warlord of the Warsong Clan, and one of the strongest mortal warriors in recent history. The fight his generally even, until Garrosh takes a risk that pays off, allowing him to get a few solid hits in, and ends with him tossing Thrall onto the ground. Realizing that Garrosh isn't going to back down, he decides enough is enough. Calling upon his shamanistic powers, he tosses Garrosh around like a piece of paper, eventually crushing him in a giant, stone fist, and calling down a bolt of lightning that ends Garrosh's life.
Like with the Everquest example listed above, a max-level player can go back and solo clear a dungeon that at the appropriate level would have required anywhere from 5 to 40 players to clear.
Binary Domain: the final stretch of the game up to the Amada AI and the Final Battle. At this point, Dan is a textbook example of Lightning Bruiser, is carrying a weapon that has been upgraded to the point that it is less of an assault rifle and more of a hyper-accurate light machine gun, has three other badasses with him that are similarly equipped, and (although it has no effect on gameplay) is in the midst of an Unstoppable Rage. Dozens of robots stand between you and your goal. The poor bastards don't stand a chance. It's entirely possible to get through the entire section without being taken down and staying far enough ahead of your AI teammates that you essentially annihilate the entire force singlehandedly.
In Saints Row 2, Johnny Gat has one with Shogo during Aisha's funeral. He beats Shogo down multiple times, telling him to get up after each one them beating him down again, even smashing him through a tombstone before finally burying him alive in Aisha's coffin.
In Saints Row: The Third, both of the Boss's fights against Killbane. The first time, Killbane manages to get a few swings in and fights back decently, but the Boss still thoroughly trounces him. The second time, Killbane doesn't even get a swing in, and the Boss just beats the hell out of him against the wreckage of his plane before finally breaking his neck.
*In Saints Row IV, the Boss gets his arse handed to them by Zinyak the first time around.
*Amusingly enough, in the DLC Enter the Dominatrix (which is based on the incomplete DLC for Saints Row the Third that eventually became Saints Row IV), Zinyak is a Zero-Effort Boss whose huge life-bar is depleted in one hit from the Boss, who then finishes him off with a Quick Time Event. Zinyak even complains about it in the in-character commentary for the scene.
In general, Covenant ships tended to deliver this to UNSC ships during the Human-Covenant War due to how much better their technology was; things have become more even post-war as the UNSC have closed much of the tech gap.
"Decimate is the wrong word, Colonel. We would have been decimated if we lost one ship out of every ten. Instead, we lost ten of our ships for every one that managed to limp away. It was a total disaster!"
And in Halo 3, we get this from Miranda Keyes about the battle for Earth:
"Truth's ships breached the lunar perimeter. Smashed what was left of the home fleet. Then, they started digging."
In-game, these can be very easy to pull off in the original Halo: Combat Evolved. The Covenant's entire weapon set revolves around CQC, with an energy SMG that can strip your shield in seconds on the highest difficulties, a homing pistol that can do the same in one shot, another homing weapon carried by higher tier enemies (and Grunts) that causes you to simply explode when shot enough, and a grenade launcher. That said, engage the Covenant with the Magnum (the first weapon you get) at any range greater than twenty feet (the gun has a scope and can kill with three headshots) and they're completely helpless. The Covenant tend to fend better against Marines armed with the MA5B assault rifle, the worst weapon in the game, although by the time "343 Guilty Spark" rolls around (and in some mods for Halo: Custom Edition), Marines carry shotguns, a weapon capable of killing anything in one hit. It becomes somewhat hilarious to watch Marines mow through section after section of Covenant infantry with nothing but a 12 gauge shotgun.
In a Tales of Xillia 2 sidequest, a Elenpios citizen who's not particularly fond of people from Riese Maxia rounds up a mob of like-minded individuals to try and run the party out of town. This works about as well as you might expect when considering that the people in question are completely ordinary and lacking any actual combat experience whatsoever. All of them save for their leader are lucky to withstand so much as a single hit, while the latter only gets the luxury of lasting a few seconds longer.
XCOM: Enemy Within: Potentially, the first open battle with EXALT. Your XCOM squad will possibly have with laser weapons and armour made from alien alloys. Your EXALT adversaries will have equivalent to flak vests and conventional bullet firing weapons. But then again, there's only 4-6 XCOM operatives present, compared to around 10-12 EXALT operatives. XCOM has technology and training on their side, while EXALT has numbers and sheer ruthlessness. This could be an interesting battle, and it could go either-... Oh, wait, nevermind, XCOM has brought a MECTrooper. Those Cool Guns that EXALT have brought may as well be paintball guns.
In Saint Seiya Ougon Densetsu, the Big Bad suffers this once you do the Puzzle Boss right. The main protagonist, Seiya, gains a large amount of energy and the ability to refill his life every turn before attacking, which pretty much nulls the boss' own attack, as strong as it is. The battle is pretty much impossible to lose, outside of having some really lousy luck.
Red Dead Redemption has Puma concolor (the cougar), which will be killing you in one hit in multiplayer mode, and just giving you one extra chance of getting away in single player. Needless to say, the cougar has gotten a reputation of being a Memetic Badass on the game's GameFAQs board.
In the single-player mode, the Battle of Fort Mercer: the game requires you to get through without a single one of your allies going down while you kill over a hundred outlaws, most of them with a gatling gun.
Entering a low level mission (such as the Old Ascalon missions) with one or more Level 20's in your party will most likely be a curb-stomp from start to finish.
In Factions, Shiro shows up in the Vizunah Square mission to confront your party. At this point, you're barely aware of Shiro's presence, and not at all aware of how powerful he is. He proceeds to quickly curb-stomp your party in a cutscene, then steal their souls. It's quickly undone when the Emissaries appear and return your souls with the snap of a finger.
A Elementalist/Mesmer with a specific build involving an Arcane Echo'd Echo'd Celestial skill can utterly return the favor. Just make sure you've got the Guardian henchman, and you'll have six Celestial Storms sitting on Shiro. His meditation cannot help him now.
Any encounter between the Xenomorph and human survivors ends with the implacable monster laughing off their firepower and ripping through them like paper. Deliberately luring the thing to them is a cruel, but legitimate tactic. Of course, if you're stupid or desperate enough to try and fight the thing yourself, you'll get your own taste of this trope.
Working Joes vs. human survivors also tend to end very badly for the humans as well.
In Chapter 12, a Working Joe tries to accost Samuels. Unfortunately for it, Samuels is a much more advanced Weyland-Yutani synthetic. The ensuing trashing is a rather better advertisement for Weyland-Yutani androids than any marketing initiative.
By the time you finish Dragon Age: Inquisition, you'll notice that against the Inquisitor, Corypheus never achieved better than a Pyrrhic victory
Planescape: Torment doesn't have many of these (in part because the Nameless One cannot die, or rather, cannot stay dead), but one moment stands out. Ravel is attacked by the Transcendent Incarnation after you defeat her. Both are extremely old and powerful entities. She dies without dealing a single point of damage to it.
Vhailor is a "Mercykiller" who died before the events of the game, and it literally held together by his burning desire to administer justice, which is so great that his strength actually increases along with the level of injustice he fights. The Transcendent Incarnation, the final boss of the game, is a part of yourself who did something so utterly evil and irredeemable that it's very existence is keeping you from dying and reaching your final punishment. Explain this to Vhailor before the fight and he gains a ludicrous boost to practically every stat and is capable of utterly trampling the Transcendent Incarnation single-handedly.
The Tau Dewa Borg Incursion. You're called in to stop another one of the Borg's hops into the Beta Quadrant, especially since this one is near New Romulus. However, when you get there, you find that the Tholians have beat you to it and wiped them out. Thus, it goes from Borg-stopping to bug squashing.
The Undine make their glorious comeback meta-wise in "A Step Between Stars" by nuking a Voth Dreadnought. While opening the door to the Jenolan Dyson Sphere.
Early in the Delta Rising expansion, you come across the wreckage of Borg ships that have been pummeled with weaponry no one knows about. You later learn that this is done by the Vaadwaur, who come back into action thanks to the Iconians.
In Kirby and the Rainbow Curse, normally, while fighting Claycia while she is being controlled by the Dark Crafter, you have to do a hard fight that involves drawing lines to block bombs and lasers. There is a way around this, though; if one is lucky enough to have a Kirby amiibo and uses it in the boss level of Level 7, one can simply use the Kirby amiibo's benefits and defeat her without having to do the hard fight in a matter of seconds if skillfully done.
In the trailer for The Witcher 3: Wild Hunt, Geralt slaughters an entire squad of Witch Hunters in the span of less than a minute. They don't even land one freaking hit on him.
Also, in the very first game, if you choose to get drunk at Shani's place and have your way with her, there's this really annoying old nanny who shrieks at you for... well, getting drunk and having your way with Shani. One of the possible responses is "die, hag". She lets out a scream, her neck stretches back like she's just had an aneursym, and she does just that. It's just as funny as it sounds.
The Chenjesu and the Mmrnmhrm state when you talk with them in Star Control II that this was fate of their fleets at the tentacles of the Ur-Quan piloting the Sa-Matra.
Also once you've bought all the weapon technologies to the Melnorme and have acquired enough resources to fit your flagship with them, this tends to be the end result of your fights even against the Ur-Quan as long as you aren't careless, of course it's not enough to end the game, though.
In Evolve these cans how up quite a bit. Story-wise, the monsters do this to Ebonstar, ripping through their automated defenses, demolishing their heavy equipment, and reducing their numbers to a few stragglers. gameplay wise, a team of hunters that doesn't coordinate or splits up will be easily picked of by the monster, or even the normal wildlife. Conversely, if the monster player is unused to evading the hunters or using the monster character the hunters will easily catch and kill it.
Occasionally, the NFL Blitz announcer will announce the current score difference (e.g. "San Francisco leads by 7!" or "New England down by 3!") However, if either team has a high enough lead, he won't bother and just announce "It's a massacre!" or "It's a blowout!"
In Undertale, just about any enemy on a No Mercy run will go down in one hit. Almost every monster is (intentionally) balanced to be challenging only to a LV 1 player, so if you've been running around on a slaughterfest, you'll spend most of the playthrough mowing down every random encounter you find. Only two exceptions to the rule exist, both characters trying to stop your killing spree, (Mettaton NEO is an exception.) and although they're still beatable, they avert this trope so hard they actually invert it.
In the backstory of the game, the war between the humans and monsters was apparently this. As in, not a single human perished. Human Souls are far, far more powerful than monster ones.
You are virtually guaranteed to be on the receiving end of one of these if you end up fighting Sans. He opens the fight with a nearly impossible-to-avoid-attack, and proceeds to throw everything in the book at you, including breaking the in-game rules by using attacks that ignore Mercy Invincibility, dodging your attacks instead of just taking them like any other monster, and even using attacks that hit you while you're in the battle screen's menus. And to top it off, he eventually just doesn't do anything on his turn, which prevents your next turn from ever starting.
The first round of the Tournament mode in Arc Style: Baseball!! 3D is so easy that you will most likely beat them 20-0 or so in your first playthrough. It also happens if you play as the Arc Stars against the CPU, unless it chooses the Arc Stars as well.
