History AwesomeBosses / Undertale

* Chapter 2's BonusBoss Spamton NEO, in a way, delivers on something fans of ''Undertale'' had wanted for years; a ''true'' battle against [[ZeroEffortBoss Mettaton NEO]]. It takes the [[UnexpectedShmupLevel Yellow SOUL]] mechanics and expands on them, adding a [[strike:charged]] [[BIG SHOT]] and power-ups that Susie and Ralsei can create using TP, while Spamton's... ''[[TalkativeLoon eccentric]]'' personality gives him a whole array of bizarre attacks for you to deal with. Topping it all off is the music, which takes elements from "Power of NEO" and "THE WORLD REVOLVING" and combines them with Spamton's own theme to incredible effect.

Fighting all of these awesome ''VideoGame/{{Undertale}}'' bosses ''will'' fill you with determination.

* The FinalBoss of No Mercy, Sans, deserves special mention as he is brutally difficult not by being powerful, but by [[DeconstructedTrope turning the conventional ideas of Turn-Based [=RPGs=] onto their heads.]] Bosses use their ultimate / special attack near the end of the fight? Hell no, he [[AlphaStrike opens the battle with his strongest attack right away]]. Bosses have a BattleIntro that they will say every time they're about to fight? He'll ''[[TalkToTheFist skip]]'' his intro to sucker-punch you. You have 99 ATK and DEF while he has 1 ATK and 1 DEF? He'll mock you for thinking numbers equal power by simply sidestepping your overkill strikes and delivering a DeathOfAThousandCuts that bypasses your DEF '''and invincibility frames'''. Turn-based [=RPGs=] are supposed to be Turn-Based? He'll attack you while you browse your menu, during your turn. You start getting used to his attack pattern? He'll start using SmashCut to trick, misdirect, and confuse you. And the best part? He ''knows'' of your Save/Load antics, and every time you die against him, [[HaveANiceDeath he]] '''[[HaveANiceDeath will]]''' [[HaveANiceDeath rub it in your face.]]

* The FinalBoss of the Neutral Route, Photoshop Flowey, is an amazing fight. The buildup for it is great, as when Flowey gets the souls that Asgore gathered, the game window closes. Upon booting the game back up, the opening sequence glitches out and your save file has been seemingly hijacked by Flowey. Selecting this file leads to a terrifying battle with the power-mad flower, who has turned into a strange but terrfying EldritchAbomination comprising photo-realistic faces, mechanical parts, and plants. You don't even get to use your menu commands at first. Instead, you simply have to survive, dodging several bizarre and erratic attacks. To cap it off, he can save state during the fight, which he can later load to catch you off guard. The whole fight in all has been compared to [[VideoGame/EarthBound Giygas]] and [[VideoGame/RadiantSilvergun Stone]][[VideoGame/{{Ikaruga}} -Like|| in its unexpected creepiness.

* Papyrus is a pretty awesome introduction to the types of bosses the game will throw at you. It's a very humorous boss fight that seems easy at first, even when he uses his telegraphed "Blue Attack"... but then [[spoiler:[[InterfaceScrew your soul/heart also turns blue, forcing you to jump to avoid his attacks]]]], which makes the fight harder, yet also makes it more fun and exciting, showing what kinds of curveballs the game might throw at you.

* Undyne's fight is just as amazing. Her first move is to turn your soul green, which prevents you from escaping but also gives your soul a kind of shield. This shield allows you to deflect her attacks -- which come at you from all sides, by the way. They also come at various speeds: at one point, [[spoiler:you're faced with an extremely slow moving attack coming at you from one side, only for ''several'' quick attacks to come at you from the other side]]. Eventually, she adds attacks that flip around to your exposed back, requiring you to spin around quickly to block them. [[spoiler:Near the end of the encounter, she throws a lot of these attacks at you, making you spin around rapidly trying to block them all.]] In some rare in-battle dialogue, the entire act of Undyne turning your soul green is stated to be her handing you another spear to fight her fairly. Picturing the fight as a sparring match between Frisk and Undyne makes the battle a whole other layer of awesome.

* Mettaton [[spoiler:EX's]] battle starts with him revealing that [[spoiler: the entire 'killer robot' routine was a hoax Alphys created with Mettaton's help to make Alphys look good. In fact, Mettaton doesn't want to kill humans; it's his lifelong dream to perform for them.]] Mettaton tells the player that Asgore will almost definitely beat them and proceed to destroy humanity, and he simply cannot let that happen. The fight includes (in no particular order): an epic [[spoiler: transformation sequence,]] unique sparing mechanics, bombs being shot out the sky, pop quizzes, viewer call-ins, a smoke machine, lots of poses, [[ItMakesSenseInContext tiny robots floating in and attacking the player with hearts,]] and [[spoiler:[[ShesGotLegs Mettaton's legs.]]]] All watched by the entire underground on live television. It ends with Mettaton realizing, after the aforementioned viewer call-ins, how much he means to his fans in the underground, and how much [[PetTheDog they mean to him.]] Still not convinced? The battle theme is called 'Death By Glamour'.
* [[spoiler:Asgore Dreemurr, King of all monsters]]. One of the few bosses you absolutely ''cannot'' spare and must defeat by force. The boss begins by [[spoiler:'''[[ViolenceIsTheOnlyOption destroying the MERCY button]]!''']] The battle has no sudden tricks to throw you off or anything you haven't faced before -- it's a pure test of your skill at dodging bullet patterns and reacting to blue and orange attacks. Even using tricks to make the battle easier, the fight is still pretty long and difficult.

* [[spoiler:Asriel Dreemurr, from the Pacifist route. SugarWiki/VisualEffectsOfAwesome plus a healthy dose of SugarWiki/AwesomeMusic with "Hopes and Dreams" is one thing. But the fact that it's an inverse of a HopelessBossFight is worked into the story; you can't lose, because your determination to save your friends and the world is strong enough to endure the pain his attacks deal to your SOUL. Even when you can't move, and can't [[ArcWords SAVE]] yourself anymore, then maybe you can save your friends. You enter Asriel's SOUL, save your friends, and even save the boss. Your determination brought you a long way.]]
* For the opposite reasons, both of the bosses exclusive to the No Mercy route, [[spoiler:Undyne the Undying and Sans]]. Respectively, [[spoiler:Undyne, basically souped up in one of the most awe-inspiring moments in the entire game and given dialogue that calls out to pretty much every climactic moment where the hero wins by pure willpower (the difference here is that you're a VillainProtagonist), as well as being given one of the best music tracks in the game,]] and [[spoiler:a boss who's fully aware of your save game antics, combining awesome music and a hectic, incredibly difficult fight into a thrilling battle, featuring a combination of new tricks and the return of the "blue attack" in a way that will make experienced players ''remember'' what they did to Papyrus. Made even better when he [[ISurrenderSuckers turns your own tricks against you]] or refuses to end his turn so you can't have yours.]] They're considered two of the [[ThatOneBoss hardest bosses in the game]] in a route where anyone playing knows damn well by now both how much they ''[[VideoGameCrueltyPunishment deserve]]'' harder fights than what the rest offer, and that [[ChallengeSeeker this is exactly what they wanted]]. For some people, in fact, throwing themselves at these two bosses is the entire ''point'' of running No Mercy.
* The FinalBoss of No Mercy deserves special mention as they are brutally difficult not by being powerful, but by turning the conventional ideas of Turn-Based [=RPGs=] onto their heads. [[spoiler: Bosses use their ultimate / special attack near the end of the fight? Hell no, they [[AlphaStrike open the battle with their strongest attack right away]]. Bosses have a BattleIntro that they will say every time they're about to fight? They'll ''[[TalkToTheFist skip]]'' their intro to Sucker-punch you. You have 99 ATK and DEF while they have 1 ATK and 1 DEF? They'll mock you for thinking numbers equal power by simply sidestepping your overkill strikes and delivering a DeathOfAThousandCuts that bypasses your DEF '''and invincibility frames'''. Turn-based [=RPGs=] are supposed to be Turn-Based? They'll attack you while you browse your menu, during your turn. You start getting used to their attack pattern?

They ''know'' of your Save/Load antics, and every time you die against them, [[HaveANiceDeath they]] '''[[HaveANiceDeath will]]''' [[HaveANiceDeath rub it in your face.]]

* Muffet's battle takes Papyrus's battle's reason for being awesome and takes it UpToEleven.

Then she curveballs ''that'' by [[InterfaceScrew making the bullet box move]] while still throwing spiders at you, which in turn precedes her sending her pet to chase you, requiring you to [[RiseToTheChallenge climb up the webs to avoid it]] [[RuleOfThree while still dodging spiders.]] While frustrating for first time players, the unique mechanics make it one of the most complex and thrilling battles in the game.
