History Characters / UndertaleMainCharacters

* DefiantToTheEnd: [[spoiler:If you choose to kill him in the Neutral run, he gives one last evil grin and proclaims "I always knew you had it in you."]]

* {{Troll}}: Enjoys messing with you, [[http://i0.kym-cdn.com/photos/images/original/001/020/845/f52.png this]] ('''spoilers''') shows how.

* ISurrenderSuckers: [[spoiler:Do you enjoy sparing people only to kill them when their guard is down? Well, if you think Sans is being sincere when he offers a truce to a mass murderer like you... [[KarmicDeath prepare to get dunked on.]] Besides just slashing him again, there's something that first-timers can look out for to realize he's faking. Remember how when enemies are in the sparing range, their names turn yellow? Sans' name does... but the "spare" option, which normally does as well, does not.]

* ISurrenderSuckers: [[spoiler:Do you enjoy sparing people only to kill them when their guard is down? Well, if you think Sans is being sincere when he offers a truce to a mass murderer like you... [[KarmicDeath prepare to get dunked on.]] Besides just slashing him again, there's something that first-timers can look out for to realize he's faking. Remember how when enemies are in the sparing range, their names turn yellow? Sans' name turns pink when he "spares" you.]]

* ISurrenderSuckers: [[spoiler:Do you enjoy sparing people only to kill them when their guard is down? Well, if you think Sans is being sincere when he offers a truce to a mass murderer like you... [[KarmicDeath prepare to get dunked on.]]]]

* VillainousFriendship: [[spoiler:With Frisk in No Mercy. Flowey is much less condescending and much more genuinely kind in this route, treating the Fallen like an old friend, which may not be far from the truth. Unfortunately, this comes back to haunt him when he realizes just how horrible Frisk really is...]]

* MeaningfulName: Asgore ''Dreamer''. He's known for his dream more than his person.
* NamesToRunAwayFromReallyFast: Just listen to his name: Asgore... Can you imagine what a guy named that could do to you? And the not-so-funny thing? He really ''can'' do what you just imagined to you, [[spoiler: though that doesn't mean he'll ''enjoy'' doing it, and he'll do his best to stave off doing it for as long as possible.]]

* ImprobableWeaponUser: Starts out armed with a stick, and moves on to a toy knife, a single leather glove, ballet shoes, a notebook, a [[FryingPanOfDoom frying pan]], and finally a gun with no ammunition. [[spoiler:The final weapon, bucking the trend, is an ''actual'' knife, although if you're not on the No Mercy path it's an old and weathered one. Also, an event at the very end of the game implies that everything but the stick and the actual knife were possessions of the each of the six people who came here before you and didn't survive. The knife is likewise implied to be the Fallen Child's.]]

* MortonsFork: When you finally fight Undyne, she'll be angry regardless of how you played: if you killed Papyrus and/or some minor monsters, Undyne will say she thought humans were compassionate, but you're just a monster. If you played as a pacifist, Undyne will say she thought humans were cool, but you're just a wimp. However, this is an unusual [[JustifiedTrope justified]] example of this trope; the monsters need your SOUL in order to achieve their dreams, so Undyne invents a reason to kill you regardless of what you do, because the fact that you still ''exist'' delays the monsters' hope.

* SeenItAllSuicide: [[spoiler: In the No Mercy route, he says that after spending so long scared of death and reliving loops through saving, loading and resetting, he's finally come back around to being ready to die for good because everything's become routine no matter what he does differently, but he also decided he doesn't want to go out alone, and [[OmnicidalManiac wants to take everything else out with him]], though on a neutral or pacifist route, he changes his plan after he sees how you go through the ruins.]]

* SeenItAllSuicide: [[spoiler: In the No Mercy route, he states that he's grown bored of living out every possible existence, seeing everything that can be done in every way it can be done, and just wants to die. However, because SAVE and LOAD prevents his permanent death, his final suicide aims to [[OmnicidalManiac take out quite a bit more than just himself]].]]

* BossRemix: "Your Best Friend", the song that plays when you first meet him in the Ruins, gets a reprise in "Your Best Nightmare", "Finale", "Hopes and Dreams", and "SAVE the World". These are, respectively, the battle themes of the two phases of [[spoiler:God/Omega Flowey]] and the two phases of the fight with [[spoiler:Asriel]], both of which are [[spoiler:more powerful forms of Flowey.]]

* {{Leitmotif}}: "Your Best Friend". [[spoiler:He gets a DarkReprise (or a dozen insane ones) in "Your Best Nightmare" for his boss battle.]]

* TheWorfEffect: You later learn that Toriel is actually [[spoiler:the former queen of the Underground]], but while Toriel is a WakeupCallBoss as described above, she's not nearly as hard as Papyrus, Undyne, or Mettaton are later on. [[JustifiedTrope Justified]], as Toriel is holding back in your boss battle with her since she has no desire to kill you.

* MeatPuppet: [[spoiler:Frisk is not truly a cipher for the player character. They're an individual with their own will, but ''extremely'' little ability to act on it. This isn't actually too horrible on a Pacifist route, as Frisk's desire mostly match up with the player's and they eventually gain enough autonomy to assert their own identity; the player can be thought of more as a guide than a controller. For No Mercy, one can only Frisk isn't [[AndIMustScream aware]] of what they're doing.]]

* MysteriousPast: We don't know a single thing about the Child's past - only that at one point they decided to climb Mt. Ebott for an ambiguous reason.

* ConditionedToAcceptHorror: [[spoiler:Attacking monsters hurts them by [[KillingIntent conveying desire to do so]]. Frisk's empathy initially causes them to resists the player's orders to attack, and thus do less damage. But, as Sans explain, hurting people drives you away from them, [[ItGetsEasier making it easier to hurt them even more]], and this is basically what your LV really measures.]]

* CorruptTheCutie: You [[spoiler:and the Fallen Child]] cause this over the course of a No Mercy run. Their true nature [[spoiler:as Frisk]] is benevolent, but a No Mercy run causes them to [[spoiler: be overtaken by the spirit of the Fallen Child and]] slowly become more sociopathic and violent. [[spoiler:CharacterLevel in this game is a measure of willingness to hurt others, so gaining ''any'' EXP represents some degree of corruption. Frisk starts the game with the lowest LV possible and zero EXP, indicating they would have never killed anyone without the player's influence.]]

* CorruptTheCutie: You [[spoiler:and the Fallen Child]] cause this over the course of a No Mercy run. Their true nature [[spoiler:as Frisk]] is benevolent, but a No Mercy run causes them to [[spoiler: be overtaken by the spirit of the Fallen Child and]] slowly become more sociopathic and violent. [[spoiler:Gaining ''any'' EXP represents some degree of corruption as CharacterLevel in this game is a measure of willingness to hurt others. Frisk starts the game with the lowest LV possible and zero EXP, indicating they would have never killing anyone without the player's influence.]]

* TheComicallySerious: They never change that overwhelmingly neutral expression of theirs, no matter how wacky, horrific, or tear-jerking a given situation might be. [[spoiler:Averted during an encounter with an Amalgamate in the True Lab, in which they [[NotSoStoic start crying]] while attempting to laugh, should the player tell them to do the latter. It's also one of the only times outside of the No Mercy run where Frisk acts (somewhat) independently of the player. It's also noticeable that they display hesitation in the bathtub area, as their walking movement suddenly slow as they approach it, and re-examining suspicious areas appear worded as if reassuring themselves.]]
* CorruptTheCutie: You [[spoiler:and the Fallen Child]] cause this over the course of a No Mercy run. Their true nature [[spoiler:as Frisk]] is benevolent, but a No Mercy run causes them to [[spoiler: be overtaken by the spirit of the Fallen Child and]] slowly become more sociopathic and violent.
* TheDeterminator: To the point that save points exist because of it. Using a save point shows that something interesting in the room makes the protagonist determined. [[spoiler:However, killing as many enemies as you can drops the fluff, and the protagonist now simply ''is'' determined.]]
** This goes ''so'' far that eventually [[spoiler: Frisk's determinator tendencies reach the realms of AntiMagic, being able to recover from fatal blows simply because they ''refuse to die''.]]

* TheReveal: [[spoiler: They have an identity that is ''not'' the person you named at the beginning of the game- their name is Frisk. You named the Fallen Child.]]

--> '''Upon [=CHECKing=] Papyrus:''' Forgettable.
--> '''Initiating battle with [[spoiler:the Monster Kid]]:''' In my way.
--> '''[=CHECKing=] [[spoiler:Monster Kid]]:''' [[SerialKiller Looks like free EXP.]]

* CombagPragmatist: Where to begin? When he gets off his lazy butt, he can be quite DangerouslyGenreSavvy. [[spoiler: When he opens up his fight with you, he begins with a dramatic monologue, then proceeds to abruptly take the first turn, instead of letting you have it. Not only that, he uses it to unload his most powerful attack. If you die, [[SNKBoss (and you will - lots)]] and come back, ready for this trick, he will ''interrupt his own monologue and launch the attack early.'' He makes up for his lack of HP/Def by simply dodging out of the way of incoming attacks (and his speech seems to imply anyone is capable of it, but no one had ever thought of doing anything except just standing there and taking your hits before now) and his attacks completely ignore your MercyInvincibility. Halfway through the battle [[ISurrenderSuckers he offers you a Mercy option]] and, if you take it, he hits you with an unavoidable OneHitKill attack. As the fight goes on, he pulls pretty much every dirty trick you can imagine, including cutting between multiple attacks, and attacking you while you're navigating the menu screen. Finally, when all else fails, he unleashes his special attack: nothing. As in, he literally stands there doing nothing, refusing to allow you to take your turn, figuring that sooner or later you'll get bored and quit.]] The whole thing is probably best summed up with this one-liner:

* DangerouslyGenreSavvy: Does not even begin to describe it. Let's review: [[spoiler: When he opens up his fight with you, he begins with a dramatic monologue, then proceeds to abruptly take the first turn, instead of letting you have it. Not only that, he uses it to unload his most powerful attack. If you die, [[SNKBoss (and you will - lots)]] and come back, ready for this trick, he will ''interrupt his own monologue and launch the attack early.''

Finally, when all else fails, he unleashes his special attack: nothing. As in, he literally stands there doing nothing, refusing to allow you to take your turn, figuring that sooner or later you'll get bored and quit.]] The whole thing is probably best summed up with this one-liner:
-->'''Sans''': huh. always wondered why people never use their strongest attack first.

* UnwittingPawn: [[spoiler: To [[BigBad Flowey]], who'd been whispering things to Papyrus in the absence of Sans since before Frisk arrived. In the route to the True Endng, it's even '''''heavily''''' implied that he had Papyrus call Frisk to send them to the True Lab, before having him call everyone to Asgore's Castle -- the latter of which was outright stated.]]

** Flowey threatens you with this [[spoiler:by overriding your save states in the Omega Flowey boss fight so you would be trapped having him kill you again and again. You manage to persevere.]]

* ExactWords: Seems to be fond of these, in keeping with his persona as a ruthless prankster: Sans never actually lies to you during his boss battle, even though the implication of his words and his actions don't line up. When asking you to Spare him, he says it would "make his job a lot easier," which is technically true in that he proceeds to kill Frisk while they are off guard, and once you do Spare him, he responds that he "won't let this go to waste," which he also doesn't... it's just that what he isn't wasting is his chance to take Frisk out cleanly.

* BrilliantButLazy: Sans is definitely this. [[spoiler:Despite all his shirking off duties and constant disappearances, not only is he well-aware of alternate playthroughs that you have made by which he will judge you accordingly but, during a full No Mercy run, '''he is literally the most powerful monster in the entire game.''']]
