Taizo Hori, hero of the original Dig Dug, and member of the Mr. Driller cast, pictured on the main page in his appearance in Namco × Capcom. Besides changing his look to one that's more realistic and rugged, the game also altered his background so that he's a former soldier in addition to being a digger of many kinds. Actually, Namco × Capcom has a lot of this.
Everyone in One Piece: Pirate Warriors. As in, One Piece characters (such as Nami, who is powerful but comparatively weak in comparison to the rest of the cast) that would realistically have very little chance of beating up powerful characters such as Logia and Haki users are perfectly capable of doing so in this. Some characters actually acknowledge this.
Nami:(after beating a strong enemy such as Teach or Akainu) "No way... I won?"
Sometimes the Crossover nature of Super Robot Wars is what provides the change for a character: take Shinji Ikari in the Alpha games, who breaks out of his usualpersonality after meeting a multitude of different characters from other Humongous Mecha series that want to befriend and socialize with him. This in turn leads to such a change he effectively Retcons the events of The End of Evangelion and averts the Downer Ending of the film in the last Alpha game! In Super Robot Wars V, which adapts the Rebuild of Evangelion saga, Shinji is able to prevent himself from initiating Third Impact, save Rei, obtain EVA-01's ultimate form and weld it to kick Mazinger ZERO's ass and help save a captured Kouji Kabuto.
Since Super Robot Wars GC, the Mazinger Z of the Mazinkaiser OVA gets a lot more screen time before its crushing defeat is played out. Even more so, in Super Robot Wars DD, that Mazinger Z gets the Jet Scrander, which it never got to use in the anime.
The Granteed mech itself in Super Robot Wars Original Generation The Moon Dwellers. Granteed, at best, was a Game-Breaker in its original incarnation thanks to the gameplay but it was just another mech the Fury have made. Come The Moon Dwellers and it now houses the soul of the Fury's guardian god, and as the Granteed Dracodeus, it supposedly has the power to take on Perfectio, a being who can't even be killed as it is the incarnation of despair itself. Finally, The Moon Dwellers ends with the Granteed Dracodeus destroying the indestructible CrossGate. Fans now see the machine as one of the most powerful machines of the entire series.
The Great Mazinger in Super Robot Wars V. While Great is strong, it's usually underpowered compared to its fellow Dynamics. Here, it's able to not only defeat Black Getter, but also fight Shin Getter to a standstill.
While Mazinkaiser was always a powerhouse, the Shin Mazinger influences allow him to be even more amazing with his attacks in Super Robot Wars X, with the machine firing its Turbo Smasher Punches while flying. Kyoshoryuku Beam, while to the same extent as Mazinger Z's, still outright melts its victim, and knocking his opponents skywards with an uppercut firing the Kaiser Nova attack at them. Oh, and let's not forget, he wrecks Mazinger ZERO's shit.
Arguably Batman himself! Arkham Batman is probably the strongest Batman incarnation of all time. In the first game, Batman: Arkham Asylum, he was injected with Scarecrow's toxin multiple times and fought through it with no rest or antidote. In the second game, Batman: Arkham City he can punch Mr. Freeze's suit with his bare hands hurting Mr. Freeze and earlier on took out the immortal Solomon Grundy. In the prequel, Batman: Arkham Origins, he defeated Lady Shiva twice, once when he was still in training; defeated Deathstroke without problems in his 2nd year; beat up Killer Croc; and Bane did the backbreaker on him....and COULDN'T break his back, unlike in the comics and Nolanverse. Really nothing more to be said.
The first game, Batman: Arkham Asylum, gives us an actually scary version of the Scarecrow. In other media, Scarecrow was just a guy dressed in a crappy Halloween costume who relied on his hallucinating drugs to strike terror in his victims. In the game, he's a Manipulative Bastard and an Evil Genius who can cause psychological horror without using his drugs. His biography describes him as one of Batman's most dangerously psychologically challenging foes. For good reason too. It gets taken to all new levels later when he becomes the Big Bad of Batman: Arkham Knight and becomes the first villain in any version of Batman ever to unmask him to the world.
Whilst Tim Drake in the comics is by no means un-badass, his Batman: Arkham City appearance definitely seems to be aiming for a grittier approach to the character, with a far more chiseled and muscled appearance, a buzz cut, and the idea that he takes part in cage-fighting in his spare time.
While most incarnations of Jason Todd are badasses in their own right, none of them are at the level of the incarnation in Arkham Knight, who leads an army of professional killers as the titular Arkham Knight, specifically trained by him to kill Batman and manages to take over Gotham in mere hours.
In the comics and most adaptations, Hugo Strange is a criminal mastermind or conman whereas in Arkham City he is a Manipulative Bastard who gets the top on all of Batman's rogues except Joker. Likewise in the comics, Hugo Strange was the first villain to learn of Batman's identity but in the original story, Strange Apparitions, it came about because he trapped Batman and unmasked him and in Prey he managed to trick Batman into revealing it, whereas here he's competent enough as a shrink to create an accurate psychological profile of Batman from a distance.
Calendar Man goes from a harmless gimmick villain to being a vicious serial killer who is genuinely menacing, while the Riddler's Super OCD leads him to build many a Death Trap, serving as a Wild Card who creates a network of informants in different factions and as an unofficial Knowledge Broker for Gotham's underworld. Mr. Freeze and Clayface likewise have a larger profile in these games, with Mr. Freeze providing Batman the most intricate Boss Fight of the entire series and Clayface being the Final Boss of Arkham City, providing the largest character model as well as being one of the few villains Batman uses lethal force against.
In Warhammer 40,000, the Tau Fire Warrior is a basic grunt unit. When adapted to Fire Warrior, the eponymous Tau grunt is able to single-handedly take on the forces of Chaos, and be able to take out several contingents of the Emperor's finest Space Marines. The novel, however, delves into some of the Tau lore and explains it a bit better: Kais is fighting a different battle, only his enemy is the very warlike and self destructive aspect that pushed the Tau to the verge of extinction that they thought they no longer had to worry about. His mentor explains that it is something every Fire Warrior has to face and come to grips with.
It's also implied that the same Fire Warrior would eventually grow into Shas'O Kais, the leader of the Tau forces in Dawn of War.
In the prequel, Laguna Loire also got this treatment. In his original game, he wasn't particularly special in combat, he fired a couple blasts from his trademark machine gun as his normal attack and for a Limit Break threw a grenade and fired his machine gun double-time. In Dissidia 012? He's the living embodiment of More Dakka, packing rocket launchers, a machine gun, various types of grenade, a sniper rifle, and a giant laser cannon in the shape of the airship Ragnarok. And his Limit Break? Calling all his weapons together to form a Wave-Motion Gun.
One of the largest upgrades happens in Final Fantasy VII with spells. Meteor and Holy had been recurring powerful Black and White spells, respectively. In the seventh installment they are boosted far beyond that to plot devices as the Black and White Materia and were capable of wiping out or defending the entire planet. The series-wide reference was lost for most western audiences due to the then lack of previous installments and inconsistent translation.note Holy was renamed to Fade, White, and Pearl in the three that made it over.
Remake greatly plays up Cloud status as an Experienced Protagonist, with him often being regarded as an veteran combat expert by other characters as well as putting on his Super Soldier traits in full force, particularly in cutscenes where he performs all kind of crazy combat feats. He's also shown to be able to defeat enemies alone (such as Reno) that he would never be able to in the original game.
In the original game, the Airbuster was something of a pushover once you managed to lock its movement, and wasn't much of a challenge. Here, if the player doesn't go out of their way to sabotage its development, it lives up to its designation as a Super Prototype.
Compared to Reno, Rude is portrayed as being very strong and more dangerous. While Cloud nearly kills Reno in their Duel Boss, Rude only stopped fighting Cloud and Aerith because he was called off, with it being treated less like a victory, and more like a draw of sorts. Notably when he shows up to fight alongside Reno in the Sector 7 Pillar, the game paints it as being much more serious now.
The Hobbit from 2003 does this to Bilbo. Sure, he doesn't get to fight trolls or dragons but he can fight hordes of goblins, giant spiders, the undead and liches. He can break enemy shields with his sword, and create a shockwave on the floor with his walking stick that sends enemies flying. And he can pole vault with the stick too.
The guy from Minecraft (who's apparently named Steve? (? included)) got this kind of treatment in his cameo appearance in the PC version of Super Meat Boy. Just like in Minecraft Steve? can both lay blocks in the game world as well as dig through anything, making the usually challenging platforming game comically easy. Essentially this ability goes so far beyond game breaking that Steve? is basically bending the game over a table and having his way with it.
Bumblebee in his Transformers: War for Cybertron incarnation is a Hot-Blooded playable character who can easily rack up a triple-digit kill count over the course of the Autobot campaign. He doesn't have the raw power of Optimus Prime but he makes up for it with speed, skill and determination.
Starscream in Transformers: Fall of Cybertron is probably the deadliest incarnation of the Decepticon to ever exist. For starters, he actually fights his enemies. Except for Megatron of course, but he did take on Optimus Prime. Despite his failures as a leader, Starscream is not a force to be reckoned with in this story.
In Persona Q: Shadow of the Labyrinth, due to the change in gameplay where everyone has a main Persona and a secondary Persona that adds moves, HP, and SP, the starting Personas for the Persona 3 and Persona 4, which are respectively Orpheus and Izanagi, are now on par with the rest of the casts' own Personas and level up normally. In their home games, they are starter Personas that are intended to be fused after Level 6 or so, due to how the nature of how their home games' fusion system works. Orpheus in particular is weak to two elements, and while he's still initially weak to them, in Q, when he evolves into Messiah, he'll lose his weakness to lightning; Izanagi will similarly lose his wind weakness when he becomes Izanagi-no-Okami.
Some of the gods in the God of War series are depicted as being much stronger than the Greek Myths presented them as:
Ares, the Big Bad of the first game, is presented as a titanic warrior the requires a MacGuffin for Kratos to have a fighting chance against, where in the Greek myths he was a coward that would run away from a fight at the first sign of trouble despite being immortal (though Ares as an Adaptational Badass is also done in every other adaption of him—including Roman mythology)
Persephone in Chains of Olympus, who was simply mentioned as being dragged off by Hades in the Greek myths, is presented as being able to fight Kratos in hand-to-hand combat.
God of War (PS4): Baldur was best known in the Norse myths for dying. Here, he is protrayed as a super-strong, fast and immortal fighter that manages to give a lot of trouble to Kratos.
Fist of the North Star: Ken's Rage featured Mamiya as a full playable character. In the series, she was shown to be reasonably affective against small groups of Mooks, but against large forces or serious Martial Artist types, she'd inevitably turn into a Distressed Damsel in need of rescuing. Being a playable character, however, means that she's now fighting on par with Kenshiro himself - tearing through armies of hundreds if not thousands, and singlehandedly disassembling top-tier bosses. It probably helps that she's picked up an Automatic Crossbow somewhere - heck, she can even pull a SECOND one out of Hammerspace for one of her Signature Moves.
Liu Shan in the original Romance of the Three Kingdoms is the definition of Sucksessor, completely inept at fighting and ruling, and in the first sight of danger, he surrenders. Dynasty Warriors turns him into an actually Badass Pacifist by the virtue of being playable. Not exactly top tier, but much more competent, savvy and in a way, virtuous like his dad, although he's a bit scatterbrained (or so he presents himself to public). On the assault on Cheng Du, he fought against Sima Zhao first before retreating, rather than surrendering on sight. Only after their next encounter he surrenders. note And the reason he surrenders wasn't because he's scared as hell, but to preserve the people of Shu from the Hopeless War brought forth by his subordinates who simply doesn't know when to quit. In 8, the implication of Hopeless War and 'subordinates who doesn't know when to quit' is absent, but Liu Shan still fought Sima Zhao as the latter enters the throne room to the end before surrendering.
Arthur from Ghosts 'n Goblins is a little guy in a suit of armor. When he appeared in Cannon Spike, he notably was changed into a giant, muscular weapon of destruction.
XCOM: Enemy Unknown saw the return of enemy types from the original X-COM: UFO Defense, with some of the more pathetic enemy types given makeovers that make them more frightening to look at and even more frightening to fight.
In the original game, floaters had pathetic accuracy and looked like bastardized Superman copies. In Enemy Unknown, they look like cybernetic abominations, are better shots, and can more easily flank your soldiers.
Mutons retain their green-and-purple coloration, but look less like burly men in jumpsuits and more like alien hulks with rebreathers and armor plating.
Chrysalids remain dangerous enemies, but now look less like cybernetic lobsters and more like large insects with blades for legs.
Jack Driscoll in the 2005 version of King Kong was a pretty meek guy whose every attempt at being heroic always inevitably failed. In Peter Jackson's King Kong: The Official Game of the Movie, however, he's the human Player Character. Despite having no military training, he wields a variety of firearms, can throw spears like a pro, and kills all sorts of dinosaurs and monsters before getting off the island.
In general, the villains of the franchise are far more competent in the games than in the show. Shredder, while not totally incompetent, is usually the Final Boss for a good reason. Occasionally he even has One-Hit Kill moves!
Compared to his canon portrayal in the original cartoon (a scrawny filthy guy who lives in the sewers talking to rats) the Rat King is the Final Boss of tournament mode (Karai is the Final Boss of the storyline mode) He has added some pro wrestling moves to his moveset, and looks like he's done more steroids than Batista.
April O'Neil too (Genesis version only), being a playable character and a full-fledged Action Girl in the game, as opposed to the Designated Victim she usually is. (Probably due to the need to include a female hero character.)
Kart Fighter is a bootleg fighting game starring the cast of Super Mario Kart (yes, really), so this was almost inevitable for half of the characters (namely Peach, Toad, Yoshi and the Koopa Troopa).
Bass.EXE from the Mega Man Battle Network series. when compared to Bass from the classic series, he went from a somewhat challenging rival of Mega Man to theBonus Boss of the franchise, and with good reason. He is also considerably more unhinged than in the Original series.
Injustice: Gods Among Us Characters like Batman are shown being able to survive being punched into orbit thanks to competitive balance. In-universe, it's the use of Kryptonian nanomachines that handwaves Badass Normal characters being able to fight toe-to-toe with Superman.
Dynasty Warriors: Gundam turns a few notable Gundam characters into this, most notably Elle Vianno, who was pretty inept with the Gundam Mk-II, and Lacus Clyne, whose only moment of piloting a Mobile Suit was guiding the Infinite Justice down to Earth.
Super Dragon Ball Z had a small cast of characters compared to the likes of Dragon Ball Z: Budokai or Dragon Ball Z: Budokai Tenkaichi, but one character playable only in Super Dragon Ball Z in particular stands out: Goku's wife, Chichi. In the original manga and anime, she hardly does any fighting after becoming a mother, and yet here she is, Power Pole and Bansho Fan in hand, throwing down with the likes of Frieza, Cell, and Majin Buu.
Captain Ginyu becomes one in Dragon Ball Xenoverse - in the animé/manga, he couldn't use the techniques of those he changed bodies with. Here, however, he's able to use Goku's Kamehameha and even go Super Saiyan with no difficulty.
Also from the same game is Krillin. In the original series, his attempt to cut Vegeta's tail to revert him from his great ape form to his original form failed, and it was Yajirobe who did it. In Xenoverse, Krillin succeeded in cutting off Vegeta's tail, and it's treated as if he did the same thing in the original timeline as well.
The two Supersonic Warriors games do this to almost every character in their story modes. It goes anywhere from small examples, like Cell becoming strong enough to beat Super Saiyan 2 Gohan with ease before going on to obliterate Majin Buu, to Can't Catch UpOut of Focus characters that completely lost relevance as early as the Frieza Saga like even KRILLIN becoming powerful enough to go toe to toe with Majin Buu and even win on their own.
This also extends to certain characters like Inkling, Charizard, and Sonic losing the Super Drowning Skills of their home series, though like everyone else, they will still drown if they stay in the water long enough.
Enforced by plot in Alien: Isolation, thanks to the addition of non-xenomorph enemies and actual weapons combined with the retention of the originally planned "sneak and hide focused" Survival Horror gameplay. In the movie continuities, xenomorphs are dangerous, but of a "Glass Cannon with acidic blood" flavor, being difficult to kill only when they can't be allowed to bleed or the humans have no weapons. In the game, the lone xenomorph is, by demands of the plot, an Implacable Man, which can't be more than staggered by any weapons the player has. This can be handwavedto an extent (the flamethrower is a jury-rigged piece of junk, the pistol and shotgun are deliberately low-velocity to avoid hull-breaches, the technology in general is less advanced than that in the second film), but when pipe bombs detonated right at the alien's feet merely scare it off, and it's immune to the bolt gun, which can oneshot kill Working Joes. This has led to backlash.
All the classes from Ragnarok Online that show up in Ragnarok Battle Offline got themselves some massive power boosts, in order to be able to deal with the many bosses that are tossed in their direction, who are also taken from Ragnarok Online and didn't exactly lose power. Curiously, some particular attacks got buffed hard enough to qualify for this, like Magnum Break going from a mediocre Splash Damage hit to a fiery whirl of sharpened death, and Lightning Storm going from a crappy AOE attack to an electric cataclysm that can fry screens worth of monsters.
Leon S. Kennedy and Claire Redfield were pretty badass in the 1998 game but theyre certainly more hardy in the remake given they can both physically repel the likes of Mr X, G-Creatures and the fully mutated William Birkin with their bare hands despite being rookies at this point in their careers. Claire in particular freely gets the Minigun in the ending unlike the original where Leon got more firepower and at the end of the second scenario both Claire and Leon respectively impale Birkins final form in the eye with a broken steel pipe effectively defeating him. Whereas in the original they just fled from him and blew up the train to kill him.
T-00 better known as Mr X was tough in the original, but could be defeated repeatedly by Claire and especially Leon with enough bullets. In the remake however... Mr X is utterly unstoppable and will only be briefly staggered by Leon and Claire's attacks (even RPG and Minigun fire) the only option is to run the hell away from him and progress the story to point where you can actually kill him.
William Birkin as the G-Monster is just as tenacious as in original game, but in this version Birkin is strong enough to take down Mr X himself by impaling him through the chest with his claws and tearing a chunk out of the Tyrant.
Remake zombies aren't just cannon fodder to fill corridors like in original, they're actual threats (especially at the start) and complete bullet sponges to boot.
Marvin Branagh in the original game was just a dying cop who spouted exposition, in the remake he saves Leon/Claire from getting munched on by zombies and is a source of comfort and guidance for the first part of the game.
Annette Birkin gets a bit of this, in the original game, she was just a Mad Scientist who shot at people and failed miserably to look after her daughter. In the remake Annette easily takes down Ada Wong twice but her motivations are more heroic as she doesnt want the T-Virus getting taken by third parties, she also loves her daughter Sherry dearly.
Ghost Survivors gives Katherine Warren this treatment albeit uncanonically, in the original and the main story she's preyed upon by Chief Irons and killed. In her Mini-Game, she kills Irons, fights through armies of zombies and escapes.
Simiarly Robert Kendo was just a poor sap who got munched by zombies and more tragically in the main game of the remake he committed suicide after being being forced to Mercy Kill his own daughter. In his Mini-Game his attempted suicide is interrupted thanks to a phone call and with will to live restored, Robert gears up and fights his way to freedom.
Even Sherry herself is much closer to Little Miss Badass compared to her helpless 1998 counterpart, Sherry in the remake actively tries to escape from Chief Irons and even wounds him with acid to face.
Hyrule Warriors does this quite extensively, as The Legend of Zelda does depend on the player via Link being the only chosen hero. The player characters vary in how they approach this. Some, such as Shiek, Darunia and Midna were implied badasses in their own games, but we never got to see them act that way. Zelda and Impa have been implied to be badasses in some of their games, but make the jump to full-fledged badasses here. And then there are those who became badasses totally under their own merit — the most prominent example of this is Agitha, who was just a slightly loopy sidequest-giver in The Legend of Zelda: Twilight Princess.
Bandit Keith is at his best in Yu-Gi-Oh! Reshef of Destruction. In the Yu-Gi-Oh! manga, he was a washed-up has-been who lost to a rookie in spite of cheating, and the anime version of him was cooler, but not by a large margin. In this game he leads the Neo Ghouls in taking over Domino, kidnapping Ishizu, and seizing the Winged Dragon of Ra, which he then duels the player with. Even after he loses the duel, he then gets you to hand over Ra anyway, and is only defeated when the card fries him with lightning. And even then, he's promptly possessed by Reshef, gets back up, and breaks the Millennium Puzzle, which lets Para and Dox steal the pieces and capture Yami Yugi.
In Yu-Gi-Oh! 5D's, Devack was a villain whose story arc was cut short, and he didn't have much presence. In Yu-Gi-Oh! BAM, he's a major villain and brainwashes you, your friends, and Kaiba thanks to his neuro-needles.
Smug Snake Dolores Umbridge gets this trope of all people in Lego Harry Potter: Years 5-7. In the original books, she is portrayed as mean, but very incompetent when it comes to actual magical knowledge and ability and is never shown participating in real combat. However, when a herd of angry centaurs fire arrows at her in the game, she employs some impressive martial arts moves, such as casually avoiding an arrow, followed a backflip and even kicking one arrow away. She is also a boss fight in the final year, in contrast to the books, where she is knocked out by a single spell.
Virtually every character counts; except for some jokes that can't do anything (like the Gonk Droid and Han Solo In Carbonite) is an example because everyone is playable so everyone needs to be capable of fighting, even if they didn't do much in the original story...or in the cutscenes of the game itself! So you can have Sam taking out hordes of orcs with a frying pan.
In Heart of the Swarm, Abathur's only purpose was evolving the Zerg. In Heroes, he's still not a fighter, but gains a wide variety of Mission Control type abilities such as summoning mines and spawning locusts, and can place a symbiote over an ally's head to aid them. Both his Heroics also involve him fighting "directly". He can either mutate a minion into a monstrosity that can be controlled, or clone an allied hero to join in the fight.
Li Li is probably a bigger example. She went from the tag-along niece of prominent brewmaster Chen Stormstout to a very powerful (if somewhat auto-piloted) healer. She even made it into the game before Chen!
Call of Cthulhu: Dark Corners of the Earth does this to the main character. In the original story The Shadow Over Innsmouth the main character visits Innsmouth on a whim and is chased out of town before passing out from terror upon seeing a Deep One. His involvement with Innsmouth ends there as the authorities take over. In the game, that's only the end of the first half of the game, with the second half seeing him return to Innsmouth with Hoover, the FBI, and the U.S. Marine Corps and personally destroying the Marsh family and the Deep Ones.
Due to its crossover nature, many a party member in Rakenzarn Tales ends up being much tougher. For example, Dirk the Daring was already badass, but here he can take more than one hit before dying. Ed, Edd n Eddy are surprisingly viable combat choices. The normally goofy Derpy Hooves can fight on the front lines as well as anyone else. And Kyuu is poised to become the most powerful party member in the game with proper training.
Minecraft: Story Mode: The Command Block is depicted as an extremely powerful artifact with properties that can greatly empower a Wither. Minecraft proper's use for them is to generally for scripting or convenience purposes in non-Creative Mode modes.
Kurisu is the only normal human note At least in the Fighting Game; she was the only normal human in the Beat 'Em Up before the Frau DLC, but she can fight and keep up with superpowered opponents with her multiple kicks, and using several lab gadgets that she takes out of nowhere, such as a Ray Gun or a flamethrower; She's also one of the two characters who have two supers.
Frau was added to Phantom Breaker: Battle Grounds as a DLC character: in Robotics;Notes, she was a brilliant programmer, but socially inept Hikkikomori, but she's more than capable of taking down her bizarre opponents using several remote-controlled robots, or with help of other characters from the visual novel.
Greedo, who's best known for being an overconfident punk that Han Solo dispatched with ease, is capable of keeping up with the likes of Boba Fett here. In the hands of a skilled player, he can even rack up quite an impressive body count.
The Red Five, Luke's ship from A New Hope, comes with firepower, speed and armor far exceeding that of a normal X-Wing along with the ability to significantly repair itself mid-flight and an invulnerable (if temporary) shield. In the films, the Red Five was completely ordinary, it was Luke's piloting that accomplished so much.
The real St. Louis class cruiser was a mediocre and ultimately failed warship which was overweight, its armor belt lay entirely below water, its broadside was mediocre, and it was too slow to bring it to bear. It was primarily known for the fact that one of its ships, USS Milwaukee, grounded on a sandbar trying to assist a grounded submarine and had to be decommissioned in place because it was too badly stuck. In World of Warships, the confined arena space means that the speed doesn't matter nearly as much; the nine-gun broadside is a serious threat to battleships at its own tier and even the tier above it; its large rudder makes it very maneuverable, with a tight tactical circle at its maximum speed; and the lack of modeling of underwater hits means that it's a very difficult ship to score citadel hits on. Overall, the same traits that made it a poor ship in the real world make it a Mighty Glacier in the game.
Batman: The Telltale Series does this with the Riddler, who's usually reduced to a pathetic joke who screws himself over between his Awesome Ego and his compulsion to leave behind clues. Here, Riddler is an international terrorist who was active before Bruce Wayne was even born, had Gotham's crimelords terrified of crossing him, and let himself get thrown into Santa Prisca (the prison that created Bane) just so he could bust it wide open mere minutes later, releasing all the inmates. During the game itself he makes use of horrific death-traps, fights Batman to a standstill despite being a couple of decades older thanks to Awesomeness by Analysis, hands Batman a moral defeat by setting up a no-win situation that even he can't thwart, and kills Lucius Fox. Oh, and he doesn't leave behind clues, either. This is later revealed to be due to being exposed to an experimental virus that enhanced his physical and mental attributes while also decreasing his mental stability.
Harley Quinn's backstory does not involve the Joker, meaning that she became a criminal by herself and thus is far more assertive and brutal. She also serves as the de-facto leader of The Pact after Riddler's death and her relationship with "John Doe" (this universe's version of Joker) inverts their typical dynamic, with John being the Sycophantic Servant while she's the one who pushes him around. At first: Joker inevitably turns the tables and assumes the role of the final antagonist.
Sauron receives a huge dose of this due to taking aspects from the movies. In the source material, he never fights anyone unless he is forced to and always end up losing. Here, he is an Physical God and a terrifying enemy so powerful the heroes can only stand against him when wielding an Ring of their own. In addition, its mentioned that Sauron lost the ability to shapeshift when his physical body was destroyed during Numenor's sinking and he was locked into a dark-lord monstrous appearance. This doesn't happen in the games, where he takes a more handsome appearance to deceive his victims into accepting his gifts.
Shelob was just a Giant Spider that even a Non-Action Guy like Samwise Gangee was able to drive away with his sword, while Sauron regards her as nothing more than his "cat" - a creature that is not entirely his, but still lives in his domain. Here she is an shadow-weaving Animalistic Abomination considered dangerous enough for Sauron to send all of his Nazgul to hunt down.
Creed: Rise to Glory takes some liberties with various characters Donnie fought (or didn't fight, or who didn't even exist) in the film Creed. Every opponent except Conlan is hyped up to be much more dangerous and important than they were in the movie - including an unnamed bouncer from the club where Donnie punched out a performer.
Jeff Wayne's War of the Worlds differs significantly from all other versions of the story by giving the Martians immunity to earthly bacteria. Theyre also playable in this version, meaning you can fully have the Martians complete their plans of conquering England with presumably the rest of the world following suit.
Azumanga Fighter is a doujin Fighting Game based on the popular manga and anime Azumanga Daioh, which is not precisely remembered for having anything to do with combat, and here they are, as powerful combatants in a fighting game which doesn't take itself too seriously, as expected from anything based on a comedy manga, the characters sports comedic moves and styles, while throwing the occasional Shout-Out to the manga series.
Tank Cat is one of the game's heroes, and is thus capable of dishing out massive amounts of damage, which is a stark contrast to its non-existent damage output in The Battle Cats.
Many of the helpers qualify, but special mention goes to:
Gold Cat is a Junk Rare in the original game, but one of the strongest helpers here.
Dread Pirate Catley is one of the weakest Cats for direct attack in the original, being made to knock back Red enemies instead of dealing damage. Here, it's the strongest helper outside of Valkyrie Cat and Bahamut Cat.
Valkyrie and Bahamut themselves are outclassed by a lot of other backliners in the original, but are the strongest helpers here.
The Rhino goes from a B-lister to someone who can easily keep the Spider-Men on their toes, even managing to defeat Peter at the start of Spider-Man: Miles Morales and only being beaten by Miles's venom blast.
Screwball is only more of a genuine supervillain than the annoying asshole she is in the comics, including managing to break some prisoners out and even being smart enough to heck Spider-Man's tech.
Hammerhead got this multiple times over. In the comics, he was knocked out during a brawl and thus was unconscious during the operation that gave him his unique metal plate, whereas in the game's backstory, he was shot in the head and not only survive, he was conscious enough to make the decision to have the plate installed. He's also smarter than the thug of the comics and his conversion into a cyborg was a decision he himself made (as opposed to Mr. Negative saving him as in the comics) and it turned him into a hulking monster rather than just merely granting him Super Strength and durability.
Spider-Man: Miles Morales does this to the Tinkerer. As opposed to the non-combatant of the comics, this version has tech that allows her to go one-on-one with Miles.
The Skaven of Total War: Warhammer II are an interesting case due to balancing; in the lore and on the tabletop, the Skaven are a race where Chronic Backstabbing Disorder is ingrained in their DNA, and their various mad science gadgets are subject to the will of the dice and might explode catastrophically the first time they fire. Translating this one-to-one in a video game would essentially make the Skaven unplayable, as a player's generals and even individual units would be constantly mutinying and anything more complex than a spear would stand a high chance of blowing up and rendering the unit lost. So in game, non-Legendary Lords have a loyalty meter that can be improved with rewards and success in battle, Skaven artillery works just as well as any other factions, and the only real infighting beyond dissatisfied lords is the occasional rebellion here and there and a number of public order penalties. This has the side effect of making the Skaven a top-tier faction verging on Game-Breaker, as they're a race that brings tanks, machine guns, and nukes to a setting where most other factions haven't figured out gunpowder weapons yet.
Siegfried from the Wild ARMs series was a fighter but he was a fairly medium level boss who your party had a habit of beating every time they fought. Then comes Wild Arms Million Memories where, not only is he a lot harder to beat (due to him having a good range and you having very little room to move on the field), the following cutscene shows he's absolutely trounced your party (of eleven people, no less.) Not only that, he's frighteningly competent at being a villain this time around; being the one to free Mother right before your party, getting Rudy (yes, that Rudy) to betray everyone he cares about in exchange for taking Mother down, and then sacrificing himself to give you a chance of saving Filgaia.
Cyberpunk 2077: The game's version of Johnny Silverhand is significantly more badass than the tabletop version. Tabletop Silverhand was pretty hard, but not the kind of guy who could go toe-to-toe with corporate spec ops units and win, like his video game counterpart. A significant portion of this stems from that video game-Silverhand is a Composite Character, who takes a lot of beats from Morgan Blackhand, including the ability to dismantle minor countries and the rivalry with Adam Smasher.
Marvel's Avengers: MODOK is no slouch in the comics, but his status as the game's Big Bad takes him up several notches. While most versions of the character had some form of resources, here he has the full public backing behind for much of the game, and manages to pose a serious threat to the Avengers, in addition to his abilities of technokinesis. By the end of the game, not only does he break out a fully-weaponized version of his rocket chair, with robotic arms and missile launchers, he also summons a reconstructed Kree Sentry.
