History ThatOneBoss / Action

* Mysterio from the first Platform/{{Playstation}} ''[[VideGame/SpiderMan2002 Spider-Man]]'' game. The method to beating Mysterio was straightforward and obvious enough, but the twitchy controls made shooting your webbing difficult at best, particularly while avoiding Mysterio's attacks. [[AnticlimaxBoss Hilariously subverted]] in the [[VideoGame/SpiderMan2 second game]] based on the movies. Mysterio's health bar fills up... three times, and then [[spoiler:you defeat him with one punch]]

* Mysterio from the first UsefulNotes/{{Playstation}} Comicbook/SpiderMan game.

[[AnticlimaxBoss Hilariously subverted]] in the second game based on the movies. His health bar fills up... three times, and then [[spoiler:you defeat him with one punch]]

* [[spoiler:Andross]] in ''VideoGame/StarFox Adventures.'' [[spoiler:It wouldn't be so bad if it weren't for the fact that the game up until that point is largely based on on-foot, Zelda-style action, and suddenly he takes the [[UnexpectedGameplayChange shooting segments]] from the starts of the levels and makes them the focal point of his fight.]] One thing that makes this fight way worse than it should be is [[spoiler:his sucking attack. It's nigh unavoidable, as opposed to the previous games in which it was an utter joke. You have to SPAM barrel rolls while boosting (you read that right, ''boosting'', not braking) as much as possible in order to slow down ''juuust'' enough to not get sucked in.]] Normally this wouldn't be an issue. And it isn't... later in the fight. If he gets you with it while he's still in the first form, [[spoiler:whichever hand you destroyed, if either at all, regenerates, so the whole first phase just resets. And unless you're SERIOUSLY skilled and can destroy both hands in one go, you're going to have to deal with this attack at least once.]]

* People who have played ''VideoGame/ToyStory'' will often comment on their nightmarish encounter with The Claw. This is officially when the game gets hard for some. You have to use Woody's pull-string to throw squeaking alien toys at the Claw before it carries Buzz off. It's harder than it sounds, particularly on the SNES, where the hit-detection on the aliens is weird. Also, you have to survive about five or six of Sid's coins before he "runs out," and Buzz gets closer to the edge each time. (Mysteriously, the storyline tells us that he has managed to capture Buzz ''and'' Woody between levels). On the UsefulNotes/SegaGenesis version, the aliens are easier to hit -- but there's this random swinging cable that you have to keep avoiding.

* ''VideoGame/{{Siren}}'' had two outstanding MadeOfIron [[MarathonBoss marathon bosses]]:

** The Stage 5 boss in ''Contra III: The Alien Wars'' is this when you're playing on the hardest difficulty. It starts out simple at first, but when the ground starts moving, you'll likely walk straight into one of the boss's flamethrowers or end up walking into the boss itself. And to top it all off, it's even hard to hit!

[[AC:Examples:]]

** ''VideoGame/GodOfWarRagnarok'' has some very good boss battles (Thor, Heimdall and the Raven Keeper are standout examples) that provide an equal balance of challenge and enjoyment. However, much like the predecessor game, the minibosses are where the dev team decided to unleash their sadism, in the form of the Berserker Gravestones; found scattered across the Nine Realms, they are the cursed souls of fallen Asgardian warriors still loyal to Odin and ''by god'' do they show why they had his favor. While most of them are very tricky and do require preparation, they are by and large beatable with diligence and watching their attack patterns (especially with [[FinalBoss the Berserker King]]). However, there is one very notable exception: Hromundr the Cruel and the Sisters of Illska. Not only are there three of them, making picking a target difficult (thank all the gods above that the two sisters share a health bar), but the enclosure of the battlefield makes it exceptionally difficult to maintain a depth of field, Hromundr '''does not stop''' attacking you no matter what and the two bitches of Illska unleash barrages of unblockable elemental attacks and AOE strikes, so you essentially have to have a 360 degree defense zone to survive! Many times, you'll find that you've beaten the sisters but are quickly struck down by Svipdagr or you manage to kill Svipdagr but then get completely wrecked by the sisters.

* Out of all the bosses in ''VideoGame/{{Bug}}'', one of them stands out as ''far'' more frustrating than the others: The swamp worm from [[BubblegloopSwamp Splot]]. Bug was on a floating platform for almost the entire battle, and getting hit even ''once'' would cause him to be knocked backwards, very likely off the platform and subsequently [[SuperDrowningSkills into the water for a watery death]] (MercyInvincibility did NOT save Bug if he touched the water). Halfway through, Bug will have to board an even smaller platform than the initial one, thus knockback and drowning death was certain if Bug took damage meaning that there was almost ''no room for error'' after this. The boss' lunging and SuperSpit attacks had to be dodged perfectly, and the player had to GoombaStomp it correctly without letting momentum throw them off course from the platform or else it's one life lost and having to do the boss fight from the start (including its overly long intro animation) again.

* ''VideoGame/ArmoredCoreVIFiresOfRubicon'': Balteus quickly established itself as one of the most difficult bosses in the game, being the last major fight in the game's first chapter (The "Attack the Watchpoint" mission) and a WakeUpCallBoss ''par excellence''. Its weapons include machine guns, shotguns, grenade launchers that will track where you're going before firing, and a MacrossMissileMassacre device that it will use a lot, all of which will quickly place you in a stagger state if you don't stay on your toes, and it says a lot that the least punishing move he has is said missile massacre. Putting Balteus into stagger is a monumental task unto itself, thanks to its Pulse Armor protecting it from any stagger damage until it breaks, in addition to it being extremely nimble and hard to pin down. After reducing its health by about a third, it then decides let out a massive AOE blast of Assult Armor energy that you need to get out of the way unless you want to see a massive chunk of your AP gone before deciding to break out its flamethrowers to attack at close range, which ''will'' quickly kill you unless you can dodge them, Stagger you if you somehow don't die, and will make you easier to stagger if he keeps hitting you with them. Also, keep in mind that before this fight, you have to do battle with another AC, Sulla, before you get to the main event of fighting Balteus. Sure, there's a checkpoint before both him and Balteus but it's not going to matter if you don't have the right build to handle both of them if and when you decide to go for a S rank on "Attack the Watchpoint".

The transition between its two phases is also often accompanied by a massive AOE attack that ''will'' kill you (or leave you mostly dead) if you don't get out of its way, fast.

* VideoGame/UltimateSpiderMan has quite a lot of these.

*** Don Octavio, who is quite difficult for the first boss. Think an old guy like him would be slow and easy to take out? [[LightningBruiser WRONG.]] You can't even hit him unless you flood the arena with tar; try to punch him when he's not in it and he counters by jumping on your head. You've also got to deal with his rushing flurries of punches and [[ShockwaveStomp ground pounds]] as well. Even though Murray has a good deal of health, he'll easily chop it off. Even when slowed, most of the time punching him will knock him out of the tar, forcing you to chase and deal with his strong attacks. And in the second phase, he gets a pretty strong [[MakeMeWannaShout projectile attack]] to deal with as well. And if you lose? Back to the very beginning for you. But then there's the bonus mission where you have to defeat him under a ''very'' strict time limit. That's no fun.

** The giant babies. They are ludicrously fast, frequently speeding into your view, stunning you with [[CollisionDamage collision damage]], then speeding back out. Good luck even hitting them. What's more, they transform into a normal, rescuable baby when they are defeated, meaning they must be beaten to finish the level.
