Undertale/Characters

Flowey
The first character that the player meets when starting a new game. A friendly little flower who introduces you to the mechanics of the game. Though its advice ends up appearing a bit odd and misleading.


 * And I Must Scream: Flowey is a flower, thus
 * : After
 * : Except in the
 * Book Ends: Flowey is
 * : In the
 * : Of the Neutral route. Technically not just the Neutral route, however.
 * : The more you find out about what Flowey is and where he came from, this trope becomes all the more glaring.
 * Not So Different: The player and Flowey, most notably if you
 * : Flowey wants to
 * The Reveal: Flowey is actually
 * Schmuck Bait: After
 * Who Wants to Live Forever?:
 * : Flowey's
 * Schmuck Bait: After
 * Who Wants to Live Forever?:
 * : Flowey's

Toriel
A friendly female monster who guides the player throughout the Tutorial Level. She insists on helping the player a great deal, perhaps more than is necessary (though the player eventually finds out why she's so overprotective).


 * Beware the Nice Ones: Toriel is powerful, and will give you a taste of it if you decide to ignore her warnings.
 * Heartwarming in Hindsight: Toriel was already heartwarming by default, but when you later discover that the reason why Toriel treated you as her child is because
 * Leitmotif: "Heartache".
 * Mother Goat
 * My Beloved Smother: Toriel treats you as her child, and keeps a close eye on you.
 * Nice Lady
 * : Depending on the route the player takes.

Sans
A funny skeleton who loves puns and often pulls pranks. The player meets Sans after leaving the ruins. He lives in Snowdin Town with his brother, Papyrus.


 * Beware the Nice Ones: If you don't, you're gonna have a bad time.
 * Brilliant but Lazy: Sans is a self-described lazy skeleton without a care in the world. However,
 * Dem Bones
 * Good Is Not Soft:
 * Hero Antagonist:
 * Joke Character: in one of the most incredible ways possible.
 * Leitmotif: "Megalovania". Although the song was composed by Toby Fox long before he made Undertale. See: Homestuck
 * Meaningful Name: Sans is derived from Comic Sans, the font which his dialogue is in. Which is also a Pun; "Comic Sans" because his name is Sans and he likes to tell jokes.
 * Neutral No Longer:
 * Skull for a Head
 * What the Hell, Player?: If the player has been cruel throughout the game, Sans will probably call you out eventually.

Papyrus
Brother of Sans. Papyrus aspires to become a member of Asgore's royal guard, and receives training from royal guard commander Undyne, who recently gave him the order to capture the player by demand of the king.


 * Dem Bones
 * The Ditz
 * Gentle Giant: Undyne mentions that Papyrus is actually very strong, and that the only reason he's meek during battle is because he's too nice and doesn't actually want to hurt anyone.
 * Good Is Dumb: Papyrus is very naive.
 * Joke Character: Downplayed. Your fight with him isn't that easy, depending on the route. But it is definitely a light-hearted battle. Papyrus also is far from weak; he's likely taking it easy on you because he dislikes fighting.
 * Leitmotif: "Bonetrousle".
 * Man Child: He's a tall skeleton who's really immature.
 * Meaningful Name Just like Sans, his name is derived from the font his dialogue is in. Papyrus also refers to a form of paper used in ancient Egypt; Bonetrousle, his theme, has a stereotypical Egyptian sounds to it.
 * Nice Guy: Papyrus always sees the good in everyone, and bears no negative feelings to any creature, be they human or monster. Despite his aspiration to become a royal guard, in truth he could hardly hurt a fly because of how nice he is; which is also why Undyne isn't granting him the position; Papyrus is powerful enough to be a royal guard, but he'd be too friendly to ever get his hands dirty.
 * Skull for a Head
 * Trademark Favorite Food: Spaghetti. He will let you know about this fact, many times.
 * Trademark Favorite Food: Spaghetti. He will let you know about this fact, many times.

Undyne
Leader of the royal guard. She hunts the player in order to deliver their SOUL to the king.


 * Action Girl
 * Blood Knight
 * Cute Monster Girl
 * Defrosting the Ice Queen:
 * Determinator: Undyne's defining character trait is how determined she is. She never gives up, not even when she's at the point of getting utterly destroyed.
 * Jerk with a Heart of Gold: She's overall quite mean, but deep down nothing matters to her more than protecting others. It becomes more literal when
 * Good Costume Switch: When she transforms into Undying Undyne.
 * Good Is Not Nice
 * Good Is Not Soft: She's eager to destroy those who seek to do evil. Even though she's done a lot of bad things herself, in the name of good
 * : When the player
 * Heel Face Turn: In a Pacifist run, she
 * Hero Antagonist:
 * Heroic Spirit: Her Undying form is this, literally. She
 * Knight Templar: She's been hunting humans, taking their SOULs and delivering them to the king. She believes this is the right thing and has complete trust in the king's vengeful mission against humanity. Though the player's actions may cause her to have second thoughts, proving to her that not all humans are bad.
 * Pet the Dog: Several cases where she does this.
 * During a Neutral/Pacifist run, if the player
 * During a
 * Tsundere: When you attempt to befriend her during a pacifist run, she clearly does warm up to you, while trying to play it cool, still calling you a "dork" and threatening to attack you.
 * Yandere: She doesn't lose her violent self when you try being her friend.
 * Tsundere: When you attempt to befriend her during a pacifist run, she clearly does warm up to you, while trying to play it cool, still calling you a "dork" and threatening to attack you.
 * Yandere: She doesn't lose her violent self when you try being her friend.

Alphys
The king's chief scientist. She's a socially awkward monster who loves anime.


 * Adorkable
 * Otaku
 * Stop Helping Me!: Alphys is a little overbearing when it comes to trying to help you during your journey.

Mettaton
An entertainment robot who also happens to be programmed to kill human beings. As a result, his shows are inclined to take a murderous turn whenever any humans are involved.


 * Anticlimax Boss: Mettaton NEO. He looks strong, but
 * Alas, Poor Villain: On the
 * Ambiguously Gay: Despite his camp behaviour, he's probably asexual, due to being a robot.
 * Camp Gay: He likes to call people "darling" and has a flamboyant attitude. At one point he
 * Pragmatic Villainy: Mettaton's primary concern is his audience, which is more important to him than killing you. Though he multi-tasks quite well...
 * Zero Effort Boss: Mettaton NEO, despite looking powerful, is no match for.

Asgore
King of the monsters. Asgore cares deeply for his subjects and is prepared to do anything to free his people, whilst protecting them from humans. He bears a serious grudge towards humanity, for several reasons, thus he decided to start collecting human souls


 * Affably Evil: He offers you tea, before realizing that there's no time for that.
 * Anticlimax Boss:
 * Anti-Villain
 * The Big Guy
 * Final Boss:
 * Knight Templar: He deems his actions as necessary for the prosperity of all monsters, but it's clear he'd end up likely causing even more suffering if his plan succeeds; his war against humans would give mankind more reasons to fear and hate monsters.
 * It's arguable whether this trope truly applies because Asgore KNOWS what he's doing isn't morally justifiable, but he feels he needs to do these things for the greater good, thus he does see his actions as the right thing overall.
 * Nice Guy: {{spoiler|He once was, before the loss of his children. He still shows shades of this afterwards, and goes back to being a nice guy at the end of the True Pacifist route.
 * {{spoiler|Redemption Equals Death}}: During a Neutral run. Luckily this trope is averted during a True Pacifist run.
 * Totalitarian Utilitarian: Asgore genuinely believes his plan will make the monsters happy. Though he views it as a matter of necessity, believing that there's no other way.
 * Well Intentioned Extremist
 * {{spoiler|Tragic Villain}}
 * {{spoiler|Tragic Villain}}

{{hardline}}

Frisk
A human who fell into the underground.


 * Determinator: Frisk doesn't give up on befriending even the most hostile of creatures, even when they're actively trying to murder Frisk. The Arc Words "determination" add to this; Frisk's whole journey is about sheer, undying determination.
 * Friend to All Living Things: Literally. His goal is to befriend everyone, even those who on the surface appear to be irredeemable.
 * Good Is Not Nice: Although devoted to not killing a single monster, Frisk isn't necessarily nice to others.
 * Jerk with a Heart of Gold: Can turn out as this, depending on how things progress.
 * Pacifist

Chara
A human who, long ago, fell into the underground.


 * Ax Crazy: Boy howdy. But that's to be expected when your endgame is to
 * Big Brother Bully: Implied by
 * This is taken to the extreme
 * Complete Monster: In a game full of antagonists who are misunderstood and friendly at first, and still posessing redeeming qualities and good points to their character at worst, Chara is a complete anomaly. Humans are bastards indeed.
 * Creepy Child: Even before, it was clear that there was something off about this kid from the start.
 * Determinator: Chara's determination is so strong that they become unstoppable.
 * He Who Fights Monsters: A very literal case of this trope. Though it's subverted as in
 * Kick the Dog: When ISN'T Chara kicking the dog!?
 * Knight Templar: Chara is implied to be doing these terrible things as an act of vengeance against humans (similar to Asgore), even though in the process they end up destroying the monster world as well.
 * Not So Different: Chara's deeds are all one massive reflection of
 * : Chara's goal ingame is to
 * Tomato in the Mirror
 * You Cannot Grasp the True Form: Ultimately it's not clear
 * Chara is recognised as
 * You Cannot Grasp the True Form: Ultimately it's not clear

Muffet
A female spider monster who runs a shop, selling baked goods. She has a low opinion of humans because she heard that they like to step on them or their their legs off.


 * Cute Monster Girl: Though, considering that female spiders eat their mate...
 * Hypocritical Humor: Whenever someone refuses to buy her wares, she considers them to be "greedy". Meanwhile she's incredibly greedy herself.

Monster Kid
A young monster who lives in Snowdin Town. He/She idolizes Undyne, leader of the royal guard, and temporarily travels with the player, hoping to see Undyne (who is currently tracking down the player).
