History Main / MarathonBoss

** In ''VideoGame/YsIAncientYsVanishedOmen'', you're evidently supposed to fight the final boss at level 24 (that being the {{Cap}} in the original UsefulNotes/PC88 version and the [[VideoGameRemake remake]]), but walkthroughs for the Platform/TurboGrafx16 version generally recommend level 40 so you're killing him by a method other than DeathOfAThousandCuts. It's a bit harder to tell what level you're supposed to be at for the second game's fights, but killing every {{Mook}} you see, then consistently hitting the boss with fully powered-up attacks, leaves you doing so little damage that you need to hit the bosses twice to even notice a change in their screen-spanning life bars.

* ''VideoGame/Destiny2'': The Ghost of the Deep Dungeon bosses Ecthar and Šimmumah ur-Nokru both have larger health pools than most raid bosses. The last boss Šimmumah ur-Nokru especially has a lot of health. Even with 3 people it can take around 2 to 3 damage cycles to fully kill. If you are doing it by yourself, it can take far more damage cycles. All the while Nokru can summon lucent moths that can quickly burst you down and you are in a room full of enemies. Even after killing Nokru(and Ecthar), the encounter doesn't end until you crush the ghost.

*** On Gin's path, you lose your demons, ALL of your demons, before going up against Babel's final form. This is annoying on your first playthrough, but your characters would probably be roughly on par with your demons so it wouldn't be THAT bad if you prepared for it. However, if you're not aware of how the fight works and are on your third or fourth playthrough, during which you probably completely relied on the end-game demons you carried over from each game, it's a good chance you'll lose due to being underleveled. Now, while the story hints at this, it's easy to assume you'd lose your demons AFTER Babel dies. Nope.
* Diablo himself in ''[[VideoGame/{{Diablo}} Diablo II]]'', who not only has a ton of HP, but most certainly ''is'' a threat. You'll spend a lot of time attacking and [[TrialAndErrorGameplay a lot of time dying]].

* ''Videogame/FinalFantasyXV'': The Adamantoise makes its return. Mercifully, it doesn't have as much HP or is as powerful as the ''XIII'' ones, but since the game doesn't have the stagger mechanic, it'll easily take at least half an hour to kill this thing.
* ''Videogame/FinalFantasyXVI'': The final boss definitely qualifies. He is first fought in a cinematic battle in which Ifrit, Phoenix, and Bahamut team up to take on a transformed version known as Ultima Prime. Clive then fights him one on one, then the player takes on the form of Ifrit Risen while Ultima himself becomes Ultima Risen, and he is afterwards fought in four separate phases as Ultimalius.

* ''VideoGame/{{Gaiapolis}}'' have it's last boss, a DraconicAbomination large enough to take up half the arena it's fought in, and has '''60''' layers of health. And it's immune to attacks when unleashing it's fiery breath, only vulnerable when you wait for it to pause, land and recharge. It only has two attacks, breathing fire and occasionally using it's claws, but the fight's going to take quite a while.

* The final bosses of both GBA ''VideoGame/GoldenSun'' games. The first game's final boss is also a SequentialBoss (and its first form being a DualBoss). Many of ''VideoGame/GoldenSun: The Lost Age'''s {{superboss}}es also qualify, most notably the Star Magician. The Dullahan can be, because it's a PuzzleBoss (unless you're massively overleveled) with attacks capable of screwing up your strategy.

** For the first Golden Sun, there was Deadbeard, who was considerably harder than the final boss because of the fact that he resided in the biggest, hardest dungeon in the game.

* The final bosses in most of the ''VideoGame/HouseOfTheDead'' games, especially The Wheel of Fate and The World (two forms and two lifebars, to boot).

* Of the six bosses in ''VideoGame/{{Iji}}'', three could be easily said to be marathon bosses, especially on higher difficulty levels; worse still is the fact that they're [[PuzzleBoss Puzzle Bosses]] who you're supposed to damage with either the arena or by reflecting one of their attacks, which serves to make the fights very repetitive. And any attempt to defeat the Sentinel ''without'' using the power fields (something you have to do if you want to get 100%), or Tor later on with Maximum Charge, ''on Ultimortal'', will effectively take you upwards of ten minutes -- and that's if you're lucky/skilled enough to beat them within that time frame. To put it into perspective, the ''maker'' of this game [[https://www.youtube.com/watch?v=67eLpLhxEPg takes more than seven minutes]] to put the second one down!

*** During her [[ThatOneBoss/KingdomHearts first stage]] [[WesternAnimation/TheLittleMermaid1989 Ursula]] who can be this if you don't know the trick, which King Triton rather vaguely tells you. [[spoiler: You have to use spells on her cauldron until it blows up in her face.]] If you don't do this, you'll have to hit her ''a lot'' because she's the ''only'' boss who doesn't take normal damage. Though, [[LevelGrinding if you level up enough]], Ursula can be easily defeated entirely without magic.

** ''VideoGame/KingdomHeartsBirthBySleep [[UpdatedRerelease Final Mix]]'' has No Heart. Like most {{superboss}}es in the series, he attacks almost constantly. On top of this he has 9 Health bars and excellent defense (Roughly 1800 HP and the most a player can ever do is 10-15 with maxed level and equipment). This amounts to 20-40 minutes of battling, monstrous compared to the 2-5 minutes typical of the series. No Heart takes so long because he is expected to be faced by multiple players at once, in a multiplayer battle, which would result in a more "reasonable" time to beat. When ''Birth By Sleep Final Mix'' was remade for the [=PS3=] (as ''2.5 HD Remix''), No Heart's HP and defense were heavily [[{{Nerf}} nerfed]] because multiplayer is no longer an option in the Playstation 3 version, resulting in a [[https://www.youtube.com/watch?v=nR0llMU8S4M&list=UU7BSMVFWQZmSqZsWUQ63o3g considerably shorter fight.]]
*** The vanilla version of the game and the UpdatedRerelease have Vanitas Remnant, a Monochrome PaletteSwap of a recurring boss throughout the game. He doesn't have much health, 200 compared to the 700 he has when you encounter the normal version at the end of the game, but has staggeringly high strength; 80 compared to his endgame normal version's 26, and extremely high defense; the Remnant has 27 defense compared to the normal endgame version's 15 defense. In addition to that, Vanitas Remnant has several devastating attacks that the normal version didn't have, including one that makes him totally invincible while he launches a series of devastating ranged attacks. But wait, there's more! He also takes 50 percent reduced damage from physical attacks, as well as 75 percent reduced damage from fire, ice and lightning attacks, and is immune to everything else, combine that will his already high defense, and you'll probably spend the entire fight hitting him for ScratchDamage unless you've done an obscene amount of level grinding. ''Then'', if you take damage at any point in the fight, it will almost OneHitKill you unless you have Second Chance and Once More equipped, due to his aforementioned staggeringly high attack, but you can't use the Cure/Cura/Curaga spell to heal yourself, or he will just use Cure/Cura/Curaga on himself instantly, healing him probably back to full health since he has so little health to begin with. So you're forced to use your limited amount of curative items, which will deplete over the course of the fight. The entire fight will probably consist of you dodging his attacks, getting in one or two scratch damage attacks, and then going right back on the defensive until he opens himself up again.

-->"Dang it!" you shout. "How many times do I have to kill you? This battle has taken over a half an hour and there's no save point!"

** And there's no easy way around ''VideoGame/LufiaTheLegendReturns'''s [[{{Superboss}} Iris]]. Not only do you have to make it through the [[MarathonLevel 200-floor]] [[BonusDungeon Ancient Cave]] just to get to her, you have to take down her 50,000 HP while she throws the game's strongest attacks at you, inflicts status ailments including the dreaded Confuse, and reflects attacks back at their users. [[PercentDamageAttack Percent Damage Attacks]] would help you here, as they do in the game's other tough boss fights...unless you didn't find any in the randomly-generated Ancient Cave. And all this [[CheckpointStarvation with no save points]] on [[UsefulNotes/GameBoyColor a battery-powered portable system]]!

** Two bosses from ''VideoGame/MetroidPrime3Corruption'' take a long if you don't know how to beat them: Mogenar and FinalBoss Aurora Unit 313. If you try to use the wrong strategy against Mogenar, its regeneration will prolong the battle more and more. However, if you attack him the right way (and are quick), his regeneration won't even factor into it. Aurora Unit 313 is even worse because it's got four different attacks, and they all take a major chunk out of your remaining energy if they hit.

** Any monster that takes a long time to kill will just be a nightmare when you have to fight more than one at the same time. The only mercy applied is that they do have a slightly lower HP.
* Some of the later bosses in the UsefulNotes/NintendoDS FPS ''Moon'' can take 192 bullets from your rifle (that being the maximum you can carry) and still be less than halfway to dead. Matters are exacerbated by the fact that sniper rifle ammunition is rare and the pistol's hard to use while dodging, so you'll be using your assault rifle for the rest of the fight, which damages bosses so little that only on the rare occasions they stop shooting at you temporarily will you be able to see their health bars going down as you pump them full of lead. Dying and retrying four or five times can lead to physical pain in one's left hand (that being the one in charge of holding down the L button to rapid-fire.)

** Among the regular bosses, Orochi stands out for the need to destroy the seal (within a bell) in his central belly, and then the eight heads one by one. There's also [[spoiler:Yami]], which has to be fought across five lenghty phases, and in them Amaterasu has to retrieve the stolen brush techniques one by one, which further prolongs the fight.
* The final boss in the original [[UsefulNotes/NintendoDS DS]] version of ''VideoGame/PacNRoll'' has five different phases, each of which are the same length as one of the previous boss fights in the game. As there are only four other bosses in the game, this one fight is longer than all of the others combined.

** In ''Rock Band'', the Endless Setlist challenges will take (on average) 5+ hours. The challenge itself is to play the entire game's tracklist in one concert. 84 songs x 3(on average though usually higher) minutes, = approximately 300 minutes, or 5 hours.

* ''VideoGame/SonicTheHedgehog'':

* Depending on your character build in ''{{Franchise/Star Wars}}:'' ''VideoGame/KnightsOfTheOldRepublic'', Malak can potentially become this. If you have no powers to take out the machines from which he drains captive Jedi, you're stuck whittling down his HP no fewer than nine times as he continues to heal himself. Keep in mind you've just fought through well over 100 enemies and so are possibly low on items, and on higher difficulties, his attacks can do around 80 points of damage -- needless to say, [[UnintentionallyUnwinnable you might be screwed.]]

* The fourth installment of ''VideoGame/SuperSmashBros'' has the final battle at the end of Classic Mode, which just keeps adding on forms as the difficulty slider increases. At the highest difficulty required to fight the battle in its entirety (7.5 in the 3DS version and 6.0 in the UsefulNotes/WiiU version), the final battle has a whopping '''''six''''' (''five'' for 3DS) phases. That's Master Hand/Crazy Hand and all of [[spoiler:Master Core's forms: Master Giant, Master Beast, Master Edges, Master Shadow, and in the Wii U version, Master Fortress]] before the whole thing is through.

** Another Tales' {{Superboss}}, [[ThatOneBoss Nebilim]] from ''VideoGame/TalesOfTheAbyss'', is basically the same, except that there's no All-Divide. Fortunately her damage output has been adjusted downward.

** A rare ''VideoGame/TalesSeries'' example in which the Marathon Boss is ''not'' a {{Superboss}}: In ''VideoGame/TalesOfDestiny 2'', [[spoiler:Fortuna]], the FinalBoss takes ''forever'' to beat. Look up videos of it on Website/YouTube, and you'll notice that they're often split into multiple parts or have most of the fight edited out. The only indication that they're going down is that the music changes.

* ''VideoGame/{{Touhou}}'':
** ''Perfect Cherry Blossom'' has [[{{Superboss}} Yukari Yakumo]], who takes ''over 10 minutes'' to defeat, and over 15 minutes if you try to time out her attacks (say, to graze for score). Many shmups take about 20-30 minutes to complete, total. And to even ''get'' to Yukari, you have to beat the [[{{Superboss}} Extra boss]] Ran Yakumo. ''Twice.'' You see, Yukari's not PCB's Extra boss. She's the Phantasm boss. No other Touhou game ''has'' a Phantasm stage.
** In general, every Extra boss in the Touhou series is relatively guilty of this. The only thing that really puts Yukari in a league of her own is her final card/attack, Danmaku Bounded Field. She's invincible during the whole thing, and it lasts for a minute and a half. Have fun. The timer for her last card stops any time you die or bomb until your invincibility wears off, unlike every other time-out card in the entire series. Have fun, indeed.

** In ''VideoGame/YsIAncientYsVanishedOmen'', you're evidently supposed to fight the final boss at level 24 (that being the {{Cap}} in the original UsefulNotes/PC88 version and the [[VideoGameRemake remake]]), but walkthroughs for the UsefulNotes/TurboGrafx16 version generally recommend level 40 so you're killing him by a method other than DeathOfAThousandCuts. It's a bit harder to tell what level you're supposed to be at for the second game's fights, but killing every {{Mook}} you see, then consistently hitting the boss with fully powered-up attacks, leaves you doing so little damage that you need to hit the bosses twice to even notice a change in their screen-spanning life bars.

** The upper echelons of the series most powerful fighters are full of these. As a result, battles at this level tend to be marathon bosses fighting each other, and their battles are known to last multiple days. One of the first such battles shown in the series is Portgas D Ace, at the time an up and coming pirate, vs Jimbei, a Warlord of the Sea with ties to the pirate Emperor Whitebeard, which took place over five days before Whitebeard intervened personally and recruited Ace.

* ''VideoGame/BorderlandsThePreSequel'' has [[spoiler:Shadow Trap]], the final boss in the Claptastic Voyage DLC. He has an ungodly amount of health and it takes a ridiculously long time just to get rid of his shields, it can easily take anywhere from 30-45 minutes to defeat him in your first playthrough, and potentially over an hour in True Vault Hunter Mode.
** The regular final boss of the game, [[spoiler:The Sentinel]], could also qualify. It has three separate phases that require depleting it's considerable shield bar, after which it disappears and transforms into another elemental form. After you do this three times, it warps back in with one final transformation where you now have to deplete its even larger health bar. Once you do this, you'd think it's over, but out of the ground comes [[spoiler:The Empyrean Sentinel]]. You now have to fight an even larger, nastier boss with three more forms, each of which has health and shield of 2-3 phases of the previous boss. While it's a nice, big target, it's also only vulnerable on one specific spot each phase. Overall, killing both forms of the final boss can easily take longer than killing the final bosses of the first two games in the series ''combined.''

* Real life example: Many of the animals early humans preyed upon before the invention of ranged weapons that allow us to safely kill them from a distance, particularly most Ice Age megafauna, and even some wildlife still preyed upon by a few select hunter-gatherer tribes today, require the hunters [[SuperPersistencePredator to constantly chase their prey for many hours]] until it is exhausted to the point that the prey can no longer escape.

* ''VideoGame/Destiny2'': The Ghost of the Deep Dungeon bosses Ecthar and Šimmumah ur-Nokru both have larger health pools than most raid bosses. The last boss Šimmumah ur-Nokru especially has a lot of health. Even with 3 people it can take around 2 to 3 damage cycles to fully kill. If you are doing it by yourself, it can take far more damage cycles. All the while Nokru can summon lucent moths that can quickly burst you down and you are in a room full of enemies.

* ''Videogame/FinalFantasyXVI'': The final boss definitely qualifies. He is first fought in a cinematic battle in which Ifrit, Phoenix, and Bahamut team up to take on a transformed version known as Ultima Prime. Clive then takes on the form of Ifrit Risen while Ultima himself becomes Ultima Risen, and he is afterwards fought in four separate phases as Ultimalius.

* In one of the ''LightNovel/SwordArtOnline'' novels, Kirito told Lizbeth of the time he participated in a raid against a floor boss that was fairly weak, but had so many hit points that it took them ''two days'' to kill. They had to fight it in shifts so that every squad in the raid party could get some sleep.

* ''VideoGame/RabiRibi'' has a few pretty long fights, but two of them stand above the rest:

* The {{Superboss}}in ''VideoGame/ShadowHearts'' that is required for the GoodEnding is a real grind. It's not particularly challenging, as its attacks don't vary much, but the fact that you have to fight it with only one character, who takes all the damage and has to do all his own healing, can make the fight last half an hour or more.

* [[spoiler:Jubileus]], the final boss of ''VideoGame/{{Bayonetta}}''. You fight her for a while and take away a bit of health, then avoid fire balls in a lava field, then ice balls in an ice field, then thunder balls in the middle of a freaking ''hurricane'', then fight her directly again for a while, then bond her with your hair and take away the last of her health, then punch her from Pluto to the sun while avoiding to [[EarthShatteringKaboom crash her into a planet]]. And ''finally'' you have to destroy what remains of her body. The whole process will take a good ten minutes even for the best players, and likely twice as much the first time.

* ''VideoGame/AbomiNation'': The FinalBoss, Awakened Furcifume, has absolutely massive HP and MP totals, dwarfing those of any other Abomi. (Naturally, [[HealthDamageAsymmetry this is the one Abomi you can't recruit for your own team]], even under Total Chaos randomization.) [[SubvertedTrope In practice, though, he's not much longer than other boss fights]], as you only need to defeat him instead of a whole team. PercentDamageAttacks also work, which can really help clean his clock.

* ''VideoGame/SuperRobotWars'' games have a bad habit of this; not only will bosses have absurdly high health, they'll frequently have [[CutscenePowerToTheMax scripted events]] where getting their health low enough just makes them restore it completely. The worst offenders are probably the ''VideoGame/SuperRobotWarsOriginalGeneration'' games. In ''Original Generation 2'', any boss worth mentioning is going to have over 100,000 HP, and the last few stages will have [[SequentialBoss lots of them in a row]]. All of the last three stages (four if you face the TrueFinalBoss) are going to have over a million HP's worth of bosses, and that doesn't even include {{Mooks}}' HP. There are also the end bosses from ''[[VideoGame/SuperRobotWarsAlpha Alpha Gaiden]]'': [[TrueFinalBoss Shu]] regens ALL his health 5 times.

A boss fight which requires a significant amount of time to defeat. Can be related to SequentialBoss, as while one part of the boss isn't long, all the parts together ''are''. Or it may simply be an extreme case of a DamageSpongeBoss. God help you if it's both. Has a good chance of happening with [[FinalBoss Final]] and {{Bonus Boss}}es. See the MarathonLevel for the level version of this, which may well have a Marathon Boss at the end.

* Amaltea, the Guild Quest Bonus Boss from ''VideoGame/ArcRiseFantasia'': High HP, multiple layers of defense against magic, physical, and Excels (single, Trinity Acts, and Excel Trinities).

* ''VideoGame/FinalFantasyV'' doesn't have a true marathon boss, per se, but it has a tactic that turns any boss into a marathon boss: Quickleak. Basically, you first have a Time Mage cast Quick, and then have them perform a Bio-based spell or attack to induce Sap status, including breaking a Bio Rod. However, you then DON'T use your other Quick turn, and wait. As [=ARavingLoon=] explained [[https://www.youtube.com/watch?v=1x7zRK-Fsv8 in this helpful video]], Quick stops the in-game timer. Because Sap is linked to the timer, it will continue to run indefinitely as long as you're still in Quick until the enemy you use it on perishes. Moreover, being in Quick means the enemy can't attack you. Because Sap is a joke status (it only hits for 7.5 dps), every enemy, including {{Bonus Boss}}es Shinryuu and Omega, are susceptible to it. ''However,'' because Sap hits for so little damage, late-game bosses, with their HP in the five digits, take a couple hours at minimum to defeat. Because you have to cast it for each part, Neo-Exdeath takes '''eight hours'''. And in all of this, you can't do anything in-game. So you can either sit around and wait...or [[https://www.youtube.com/watch?v=ryzaT1s8alI play a game of golf]].

** {{Bonus Boss}}es Ruby and Emerald Weapons. Emerald Weapon is a particularly cruel case in that the game gives you a 20-minute time limit to beat it, unless one of the characters is equipped with a [[GuideDangIt stupidly obscure piece of materia]], which is more or less mandatory if you don't have a special strategy in mind.

* The final bosses of both GBA ''VideoGame/GoldenSun'' games. The first game's final boss is also a SequentialBoss (and its first form being a DualBoss). Many of ''VideoGame/GoldenSun: The Lost Age'''s {{Bonus Boss}}es also qualify, most notably the Star Magician. The Dullahan can be, because it's a PuzzleBoss (unless you're massively overleveled) with attacks capable of screwing up your strategy.

*** One of the bonus bosses, the Ice Titan, is a pain because the primary way to damage it is to deflect one of its attacks back at it, which as the fight goes on, it will do less and less, and often whilst you are in no position to be able to deflect it.
*** Sephiroth, another bonus boss, is easier to damage, but has a ridiculously large shield to whittle down before his health bar even begins to deplete, and has attacks which will almost kill you, even at full health. He's mostly the same in the second game, where he has 15 health bars (the final boss has at most 7/8).

** ''VideoGame/KingdomHeartsBirthBySleep [[UpdatedRerelease Final Mix]]'' has No Heart. Like most {{Bonus Boss}}es in the series, he attacks almost constantly. On top of this he has 9 Health bars and excellent defense (Roughly 1800 HP and the most a player can ever do is 10-15 with maxed level and equipment). This amounts to 20-40 minutes of battling, monstrous compared to the 2-5 minutes typical of the series. No Heart takes so long because he is expected to be faced by multiple players at once, in a multiplayer battle, which would result in a more "reasonable" time to beat. When ''Birth By Sleep Final Mix'' was remade for the [=PS3=] (as ''2.5 HD Remix''), No Heart's HP and defense were heavily [[{{Nerf}} nerfed]] because multiplayer is no longer an option in the Playstation 3 version, resulting in a [[https://www.youtube.com/watch?v=nR0llMU8S4M&list=UU7BSMVFWQZmSqZsWUQ63o3g considerably shorter fight.]]

*** Rather fittingly, the bonus boss to end all bonus bosses in the franchise, ''VideoGame/KingdomHeartsIIIReMind'''s Yozora, will take you an absolute age to come out on top against, assuming you can at all. For starters, he has ''20'' life bars, more than any other boss in the whole franchise. And this doesn't take into account his high defense and the ridiculous amount of highly-damaging attacks he has, one of which can steal your items, and another of which can steal your weapon. And this isn't even the worst part. [[spoiler:One of the items he can steal is your Kupo Coin, an AutoRevive that replenishes your HP to full if you take a lethal blow. And if you deplete his health after he's done this, he goes into a fake death animation before getting 10 of his life bars back]].

* ''VideoGame/ShinMegamiTenseiIV'' has the {{DLC}} {{Bonus Boss}}es Ancient of Days and Sanat Kumaya. The former especially, as it has Diarahan (a spell that restores ''all of its health'') and it will spam it if you hit its weakness (this forces you to get ''another'' DLC that provides the only source of the Brand ability other than Ancient of Days himself). The third DLC {{Superboss}}, Masakado's Shadow, would be this if not for the fact that it has a turn limit, especially since it doesn't hit terribly hard compared to the other two.

** The Celestial Queen and Lenneth, while not even possessing a fraction of her power can drag on for an eternity. Raise Fayt's defense to the point that he takes zero damage from their attacks, and the fight still drags on for on the upper echelon of 45 minutes. Ridiculous doesn't even begin to describe ''VideoGame/StarOceanTillTheEndOfTime'''s {{Bonus Boss}}es.
* In ''VideoGame/StarOceanTheLastHope'', many story line bosses and {{Bonus Boss}}es can go on for an hour or more. The final boss has around 2 million HP on Galaxy ([[IdiosyncraticDifficultyLevels Normal]]) mode.

** The ClimaxBoss of Lostbelt 7, [[spoiler:ORT]], is possibly [[SerialEscalation the most extreme example in the game]]. Not only are they a SequentialBoss, but [[ExaggeratedTrope its second and fourth form count on their own]]! For clarification

*** Most raid bosses have at most three health bars. [[spoiler:ORT]] had ''ten'' in both of its raid phases.
*** The first raid phase has ''1 million hp per health bar''.
