History GameBreaker / Action

* The game ''Psychic World'' for the UsefulNotes/SegaMasterSystem and UsefulNotes/GameGear gives you an Invincibility skill that costs a moderate amount of energy to use. It also gives you a move that turns HP into energy at a very favorable exchange rate. By using them together, you can be invulnerable to damage for the entire duration of the game.

* The UsefulNotes/GameBoyAdvance ''Manga/ShamanKing Master of Spirits'' has Black Raven, Michael, and Golem. To put it simply, Black Raven increases Spirit regeneration, which allowed you to use more Spirit attacks, which is essential on the game to deal higher damage. Michael and Golem are, in a simple term, a splitted version of Amidamaru's Antiquity upgrade, which unleashes a {{BFS}} that cuts 235 degrees and can hit walls. Instead, Michael is a fast middle range projectile that can go through walls. Golem fires a full screen fast Laser beam that hits 180 degrees of the screen, but did not go past the wall. Both of these attacks consume way less energy than Amidamaru's Antiquity upgrade, and deal respectable damage on its own right that match the likes of said upgrade and [[spoiler:Matamune]]. The use of Golem and Michael renders the final level a total joke (that is if you can beat [[EliteMook Golem]]) and made both the BigBad and the FinalBoss of the first game a joke. While still devastating in the second game, the FinalBoss restricts you to only use Amidamaru as your spirit in the final battle.

** Augment Gold can be transmuted from Augment Luck and a single lump of gold, and fully upgraded to rank 9 for a total of 9 ectoplasms and 3 holy waters (bought for a peasants wage) and three additional gold lumps. Setting this fully ranked as your passive shard (which will double-stack its effect) will make every torch in the game drop at least 500GP and very commonly drop 1000GP and 2000GP bags, in a game where torches normally drop between 1 and 10[[note]]though they can drop 50 and eventually 100, depending on your Luck stat[[/note]] and 500 is considered rare from a chest. With this in effect you can run back and forth between Johannes' room and the hallway, smacking those same two torches over and over, and amass an absurd wealth of 100,000GP in about 10 minutes, or combine it with Accelerator and [[https://www.youtube.com/watch?v=6GYKThrY3LA just look at Rockefeller go]].
*** With that, you now have absurd access to resources. This ludicrous flow of funds means unlimited alkahests, meaning you can break down any item you find to add it to the shop, from weapons to items to foodstuffs, to be boughten and canibalized for components, allowing you to quickly upgrade shards and prepare new foods for stat bonuses.

** ''GameBreaker/TheLegendOfZeldaBreathOfTheWild''

* ''GameBreaker/TheLegendOfZeldaBreathOfTheWild''

** ''VideoGame/HyruleWarriors'' is talked about in the ''Franchise/TheLegendOfZelda'' section.
* ''Franchise/TheLegendOfZelda'':
** The Bombos Medallion in ''VideoGame/TheLegendOfZeldaALinkToThePast''. It destroys all non-boss enemies on the screen.
** The Biggoron Sword in ''VideoGame/TheLegendOfZeldaOcarinaOfTime''. Twice as powerful as the Master Sword, no less.
*** The programmers tried to combat this by making your shield useless while the Biggoron Sword is equipped, but you only need the shield in rare situations. One can equip the Master Sword when the shield is needed and immediately switch back when it isn't. Unlike The Great Fairy Sword, you can also acquire the Biggoron Sword fairly early in the game, as soon as you become an adult.
** The [[GuideDangIt Great Fairy Sword]] in ''VideoGame/TheLegendOfZeldaMajorasMask'' is the same weapon in practice, but it comes so late in the game and it's such an unbelievable huge task to get a hold of that most players don't bother with it. Also, when you acquire all of the other masks, you receive the last mask, the [[spoiler:Fierce Deity Mask]] which makes Link so powerful that even the last boss is a joke.
*** Combining the Bunny Hood with the Great Fairy Sword makes it even more overpowered thanks to how fast Link becomes it means he can run circles around enemies with a super strong weapon.
*** The Stone Mask. Most non-transformation masks in the game are very situational, but this one has an ability that's almost always useful; all enemies, except for minibosses and actual bosses, will completely ignore you, which is just as devastating as it sounds. It's [[GuideDangIt hard to find if you don't know where to look for it]], but when you do the game becomes very easy. The remake makes the Stone Mask even better (and helpful) in that the man who gives you the mask has been moved to a point you'll be bound to travel earlier in the game (the Pirates' Fortress).
*** While rupees are lost by traveling back to the first day, the game has so many easy ways of getting them that it doesn't matter when you know where to look. Hundred rupee chests around Clock Town that reset every cycle, 4 Redeads in Ikana castle when you leave the room that are in that yield 15-20 rupees each, and in addition the above mentioned Stone Mask, there are other masks that cause them to ignore making them laughably easy to kill. The Takkuri bird, while it takes all your rupees if hits you, can be made harmless by wearing the Stone Mask or riding Epona, since while on her Link is immune to damage, meaning it can be killed easily without any risk. Then there's the fact that shooting a Blue Bubble with a Light Arrow causes it to drop a ''purple rupee'' (50)... and they're all over Termina Field at night, respawn when you leave and come back, and there are tons of arrow and magic refills in Termina Field.
*** Chateau Romani, while it takes a few quests to get, give Link an infinite magic meter until he resets time. This means he can use anything that requires magic without any restrictions and also makes the set of dungeons on the moon a joke since the time limit for the game is removed there.
** In ''VideoGame/TheLegendOfZeldaTheWindWaker [[UpdatedRerelease HD]]'', there is the Magic Armor, which makes Link completely invincible. In the original game it was AwesomeButImpractical since it constantly drained MP and its effect vanished when MP hit 0, but in this version it drains Rupees instead, and only when Link is actually hit. Since this version also gives the player a lot more Rupees to work with (we're talking almost a full 5000 Rupee wallet's worth), the Magic Armor can be used essentially forever, removing any challenge from the game.
*** It gets even worse when combined with Elixir Soup, which doubles the damage Link's sword deals and lasts until the first time Link takes damage. Since the Magic Armor means that'll happen exactly never, Elixir Soup never wears off - resulting in a Link who is not only invincible, but dealing absurd amounts of damage with basic combos.
** ''VideoGame/TheLegendOfZeldaALinkBetweenWorlds'' has these, mostly in the optional moves and upgrades you can get.
*** There's the Upgraded Spin Attack for starters. Oh sure, you have to find all 100 Malamais to get it, but it's so ridiculously powerful that it takes down nearly any enemy, boss or mini boss in two hits, has a range about as wide as half the screen and can rip whole hordes of monsters apart in seconds. The minute you get this, the BonusDungeon basically loses about half its difficulty, as does anything left in the quest.
*** The Nice Fire Rod. The upgraded version shoots out a huge pillar of fire with a massive range that can stun lock enemies and push them backwards while doing a ton of damage, and can even hit flying monsters. It can be gotten as early as the fourth dungeon in theory, since you only need to be able to buy it and find just 10 Malamais to upgrade it.
*** The Nice Ice Rod. Drops four large chunks of ice on enemies, with both a fairly decent range and the bonus of being able to hit things on higher ledges and in the air. Oh, and because it's ice based, enemies get frozen solid upon being hit (with a few exceptions), allowing you to one hit kill them afterwards with any melee or fire based weapon.
*** The Tornado Rod. It stuns whatever's around you, making it an extremely useful defense against any enemy that primarily attacks by [[CollisionDamage touching you]], which is nearly everything in the game. Then you have the Nice Tornado Rod, which increases its range even more.
*** Just about any Nice item to be honest would probably fit here if used well, since their effects let you just power straight through your enemies with stuff like spreadshots, very quick firing/reloading times and the ability to stun enemies.
** ''VideoGame/HyruleWarriors'' has quite a bit of gamebreaking piled up on Young Link. His main mechanic being that his attacks are normally clumsy and short-ranged and in Focus Spirit he turns into a LightningBruiser who spams sword beams with every move, he has three main advantages which help him stay in Focus Spirit: his Strong attack making him play the Song of Time converting his Musou meter into magic power (making him the only character who can regain Magic without pots after reaching the last KO streak milestone), the magic meter stopping depleting when he executes a Weakpoint Smash or using the Strong Attack, and the fact that if he runs out of magic while using his C6 he won't revert back to normal until he's finished the move, giving him the chance to score some more KO's, reach a milestone and extend his rampage.
*** While he won't be doing it for more than short bursts at the beginning, [[MagikarpPower fully upgrading his Focus Spirit and Special meters]] will make him able to potentially stay in Focus Spirit for the entire battle once you get the ball rolling.
*** And then the ''Legends'' version adds My Fairies, which possess a wide array of usable skills. Some of which fill up your magic and/or special meter. Forget getting the ball rolling, Young Link can turn into a killing machine the moment the battle begins.

** Augment Gold can be transmuted from Augment Luck and a single lump of gold, and fully upgraded to rank 9 for a total of 9 ectoplasms and 3 holy waters (bought for a peasants wage) and three additional gold lumps. Setting this fully ranked as your passive shard (which will double-stack its effect) will make every torch in the game drop at least 500GP and very commonly drop 1000GP and 2000GP bags, in a game where torches normally drop between 1 and 10[[note]]though they can drop 50 and eventually 100, depending on your Luck stat[[/note]] and 500 is considered rare from a chest. With this in effect you can run back and forth between Lohanne's room and the hallway, smacking those same two torches over and over, and amass an absurd wealth of 100,000GP in about 10 minutes, or combine it with Accelerator and [[https://www.youtube.com/watch?v=6GYKThrY3LA just look at Rockefeller go]].

** ''VideoGame/OnePiecePirateWarriors 3'' has many characters that are blatantly overpowered, as is the norm for any musou game. The one that trumps them all, however, is Admiral Fujitora. His attacks are fast, hit dozens of times in a single combo, and he can activate his [[GravityMaster Fuwa Fuwa No Mi]] to stun enemies and summon meteors from space. What makes him a Game Breaker, however, is his R1 move: a chargeable attack that summons a meteor to fall at a location near you. What makes THAT game-breaking is that fact that, when fully charged, the meteor will impact an area the size of a city block and do enough damage to instantly kill all Mooks and most, if not all strong enemies. He can do this with no cooldown, at no cost, and [[UpToEleven during a Kizuna rush, where attacks of that caliber are usually replaced.]] The only catch is that if he gets hit before the meteor falls (which, if fully charged, takes a total of 3 seconds), the meteor is cancelled. But then you can just try again.

** The Rhava Velar will utterly ''tear the game apart''. Anyone who remembers the ludicrously overpowered Crissaegrim from ''VideoGame/CastlevaniaSymphonyOfTheNight'' will be pleased to know this weapon is literally identical, with such ridiculous attack speed that it tears enemies and bosses apart in seconds with impugnity. The best part is, rather than being forced to rely on the ridiculously low odds of an ultra-rare drop, the Rhava Velar is crafted with uncommon but easily acquired later game items.

** Augment Gold can be transmuted from Augment Luck and a single lump of gold, and fully upgraded to rank 9 for a total of 9 ectoplasms and 3 holy waters (bought for a peasants wage) and three additional gold lumps. Setting this fully ranked as your passive shard (which will double-stack its effect) will make every torch in the game drop at least 500GP and very commonly drop 1000GP and 2000GP bags, in a game where torches normally drop between 1 and 10 and 500 is considered rare from a chest. With this in effect you can run back and forth between Lohanne's room and the hallway, smacking those same two torches over and over, and amass an absurd wealth of 100,000GP in about 10 minutes, or combine it with Accelerator and [[https://www.youtube.com/watch?v=6GYKThrY3LA just look at Rockefeller go]].
** With that, you now have absurd access to resources. This ludicrous flow of funds means unlimited alkahests, meaning you can break down any item you find to add it to the shop, from weapons to items to foodstuffs, to be boughten and canibalized for components, allowing you to quickly upgrade shards and prepare new foods for stat bonuses.
** Which segues nicely to the Gold Power Ring, which boosts your attack power based on your wealth. It only takes around 10,000GP to noticeably increase your damage output, so imagine what you could accomplish with ten or fifty times that.

** While it can't be done until very late in the game, defeating a certain BonusBoss and getting access to having all of O.D's books equipped at once basically turns Miriam's stroll through the castle into a fast-paced nuclear-powered MookHorrorShow. If you don't care about spoilers, [[spoiler:complete 90% of the map, check out the new tome that O.D. lets you check out, head through the Glacial Tomb, and learn that O.D. was '''''not''''' kidding when he told you not to run off with that book...]]

''VideoGame/LegoStarWars''

** In ''VideoGame/TheLegoMovieTheGame'' Superman, Wonder Woman, Green Lantern, and [[spoiler:Ghost Vitruvius]] break the game wide open since they can fly, which renders nearly all the puzzle solving and many other characters special abilities completely unnecessary. Why find pieces and build that unstable bridge for Vitruvius or extinguish that flame when you can just fly over it? Justified, however, as these characters aren't unlocked until the final mission has been completed and it would take a conscious effort to ''not'' have most of secrets found at this point.

** Some of the unlockable Extras in ''VideoGame/LegoStarWars'' make the game ridiculously easy to beat, even ThatOneLevel, though actually finding some of them often results in GuideDangIt.
*** In ''VideoGame/LegoStarWars Saga Edition,'' Deflect Bolts causes all blaster shots that would hit you to ricochet off. Since pretty much every standard enemy in the game uses blasters (except Gamorrean Guards, which you only fight twice), this amounts to a cheaper version of invincibility for 80% of the game. If you want to be a total asshole, add on Perfect Deflect, which causes all deflected blaster shots to ricochet back into the person who fired them, making all enemies immediately kill themselves upon seeing you. And if you add on [[ThereIsNoKillLikeOverkill Exploding Blaster Bolts...]]

* ''[[GameBreaker/AssassinsCreed Assassin's Creed]]''

** ''VideoGame/StarFoxCommand'' has the Black Rose, a ship exclusive to Panther Caruso. At first glance, it seems to be a horrible ship - it's made of cardboard, has no lock-on, and its bomb capacity maxes out at 1. However, its basic laser attack is overpowered to an absurd degree. It can one-shot many of the endgame-level enemies, and those it can't are nearly always two-shotted. It can kill boss-level enemies in ten shots, and the final boss in around twenty. It also has a hitbox that is so much larger than its sprite, you would think it was a WaveMotionGun; this means that aiming in something's general vicinity pretty much means you will hit it. Oh, and to make up for the aforementioned [[BuffySpeak made-of-cardboardness]] of the Black Rose, it is tied with the Arwing II and Wolfen for the second best [[DoABarrelRoll barrel roll]] in the game - in a game where the barrel roll [[SpinToDeflectStuff nullifies ALL damage]].

*** It gets even worse when combined with Elixir Soup, which doubles the damage Link's sword deals and lasts until the first time Link takes damage. Since the Magic Armor means that'll happen exactly never, Elixir Soup never wears off - resulting in a Link who is not only invincible, but dealing absurd amounts of damage with basic combos.

* ''VideoGame/StreetsOfRage 2'' has Axel's Grand Upper special. A brief introduction; all four player characters have three main special moves; standing-A, a power attack that slightly reduces your health if it hits, forward-A, a strong attack that decreases your health ''regardless'' of whether it hits or not, and forward-forward-B, a special that doesn't harm you. The problem? ''Axel's Grand Upper is his forward-forward-B, and is more powerful than his or anyone else's forward-A move''. Axel is invincible for the entire animation (it can be used to slide straight ''through'' projectiles and attack bikers without jumping over their bikes), it scores a hit on every single frame, hits anyone who touches Axel's sprite from any direction at any time, and slides forward until Axel hits something if he does it away from someone. About the only enemies who can deal with it are those with long counter-moves that can wait it out (so that'd be the bosses Abadede, R. Bear, and ''absolutely nobody else''), Shiva (who had roughly the same attack with the slide run out to most of the screen) and Mr. X.

* Wolf in the multiplayer mode of ''VideoGame/StarFox Assault'' has the highest health and speed stats in the game, and the only balance on him is that he has a smaller targeting reticule when riding an Arwing or Landmaster. He is the only character who can survive a Demon Sniper shot, just to give an idea of his durability,

** ''VideoGame/StarFox Command'' has the Black Rose, a ship exclusive to Panther Caruso. At first glance, it seems to be a horrible ship - it's made of cardboard, has no lock-on, and its bomb capacity maxes out at 1. However, its basic laser attack is overpowered to an absurd degree.
