Top Ten Most Evil Undertale Characters

The Top Ten
1 Frisk

Everyone keeps blaming Chara. "Oh, Chara made Frisk kill Papy! I totally didn't kill him with the tough glove!" (I actually heard one of my friends say this.) Dude, we don't even meet Chara until after the genocide run. They also try to stop you in a few spots. If it was up to me, Chara would be a lot more like a "Guardian of the Underground." So stop saying they're evil just because you don't want to take the blame. Chara's innocent, but you aren't.

Okay, I hate people blaming Chara for everything that goes on in the genocide run. It's kind of like, "Oh, I didn't do all this," *sees Chara* "Oh, look! S/he's standing in front of me, so s/he must be the one responsible!" She is none other than the person that everyone blames, when in reality, "it's you." But I guess in your reality, Chara is the villain, when s/he really isn't. Well, I'll leave you be.

2 Flowey Flowey is a flower in the RPG Undertale. He is the first character you meet, and also your best friend.

Flowey is... I think pretty evil, but he kinda... couldn't not be evil? I mean, he had no soul, which means he couldn't feel for anyone, so he just pushed them away from his life. Plus, as the game said (I think XD), the more you distance yourself, the easier it is to hurt people.

Flowey started to distance himself, and his curiosity took control of him. He said in the genocide route he wanted to know what would happen if he killed them... and... uh... I'm rambling, aren't I...

Hmm, why could Flowey be here? Maybe because:
He killed everyone multiple times.
He tried to kill a child.
He absorbed your friends' souls when you thought you were going to get a good ending.
He mocks multiple people.

The only good point he has is he can't really not be evil because he literally has no soul. That's it.

3 Chara Chara is a character in the game Undertale by Toby "Radiation" Fox who is one of the seven people to fall to the Underground prior to the fall of the player character. Their name can be changed by the player and will be assumed as the player character, until the Pacifist Route when Asriel asks for the... read more

I feel like she actually should've been number 1. She takes over Frisk's soul entirely. And you should know what happened when she did. She was on a rampage, killing monsters without mercy, and even killed Papyrus, who never threatened to kill Frisk.

She destroys everything no matter how you decide and then steals your soul! She should definitely be number 1, as she is the true Satan of Undertale. She then haunts you for the rest of your time playing Undertale. If you play the pacifist route after doing the genocide route, she brings you into an after-game genocide route and kills all of the monsters just when they've made it to the surface!

She has no remorse for her actions. She is no longer human. She's a demon!

4 Asgore Asgore Dreemurr is a boss monster and the king of the monsters in the 2015 RPG Undertale made by Toby Fox. Asgore is the portrayed main antagonist who plans to acquire seven human souls and use their power to break the barrier that seals the monsters underground . Aspects of his character are hinted... read more

Asgore is kind of evil. He declares war on humans and takes the souls of six humans, with the help of Undyne and possibly some other monsters. He did it because humans had taken everything from monsters, especially Asgore. He lost his son to humans, so he declared war out of anger. He then regrets his actions.

Asgore declares war based on anger, which is something that almost anyone would do in that situation. Really, it's the humans' fault.

He only needs one soul to cross the barrier. Don't you think it's a little suspicious that he goes on to kill five more? I personally think he is doing it for fun, no matter how innocent he seems.

5 Mettaton Mettaton is a character in the popular 2015 RPG game, Undertale. He is a robot with a soul built by Dr. Alphys, and is the sole television star of the underground. Mettaton is a popular character in the fanbase. His notable features include his legs, and his catchphrase "OH YESSSS!"

Mettaton tries to kill a child for public fame. If we didn't see his change of heart by the end of his part of the game, he might've been the most evil character in the game. However, he changes his ways and ultimately doesn't kill anybody.

A terrible monster, abandoned his cousin for fame, tried to kill a child for views, stressed out his creator, and never apologized. Just terrible.

He is evil at first, trying to kill the human for no reason. But after a while, he becomes a pretty good guy!

6 Omega Flowey

He is evil! He absorbed every being in the Underground's soul. He is truly evil.

I mean, I guess he's evil, but is it really his fault? He doesn't have a soul.

Listen to him laugh, do it twice, then come back and vote for him.

7 Undyne Undyne is a main character in Toby Fox's 2015 RPG, Undertale. She is the heroic fishlike captain of the Royal Guard, who takes it upon herself to protect the monsters of the Underground. Her name is derived from the word "Undine", and is a pun on the word "Undying". Her most loved monsters are her mentor,... read more

Undyne has no remorse for humans and tries to kill you. Is she evil? No. But she has probably killed at least one human before you. She was just following the orders of her king.

Undyne is just defending the Underground from your shenanigans, especially in the genocide route! The player is the most evil!

Wants you dead because you were defending yourself. I mean, who does that?

8 Sans Sans or Sans the Skeleton is a character in the 2015 RPG Undertale created by Toby Fox. He is a lazy, pun-loving skeleton who is a supporting protagonist in the "pacifist" and "neutral" routes of Undertale, and a heroic antagonist/final boss of the "genocide" route. He is known for his incredibly difficult... read more

He will be as ruthless as Undyne the Undying if you take the genocide route. He is the genocide final boss.

9 Jerry

This monster is the most evil of them all. He's merciless and can murder you with sheer annoyance.

He is the reason everything bad in the universe happens. We must make sure we burn him.

No one likes Jerry because he is evil. Fin.

10 Alphys Alphys is an adorably dorky, lab-coat-wearing, bespectacled, yellow-skinned lizard scientist who resides in her lab in Hotland in the critically acclaimed cult classic RPG known as Undertale, wherein she partakes in the daily act of watching insane amounts of anime and having a vast majority of the... read more

She reactivated traps that could have killed you and sent Mettaton to torment you, all so you would think she's a good person.

She wanted to look "cool" and was basically being evil because of it.

Her lies put you in danger.

Also, she made the amalgamates.

The Contenders
11 Mad Dummy

He fires his dummy companions, hires robot replacements, fires them, then throws a knife at you.

You would have been unable to leave if Napstablook hadn't shown up.

12 Asriel

He wants to literally reset the world and hold victory right away from you.

Asriel is just like Flowey. He lied to you and tried to kill you at the beginning of the game. Then he absorbed the souls to try to destroy the timeline.

He wasn't always evil, but because of losing his soul, he did become evil.

13 Muffet Muffet is a character from the game Undertale. She appears in a region called Hotland, selling pastries to raise money to rent a heated limo to help the spider clan from the Ruins (who are also raising a bake sale) reunite with the one in Hotland because the spiders can't cross Snowdin.

Not completely evil, she does care about her spider friends, but she is stingy with her money.

She was willing to kill a child for money. Plus, all spiders are evil by default.

Muffet traps you and bombards you with spiders. I died at least 20 times to her when I played the game.

14 Papyrus Papyrus is a character from the 2015 game Undertale, made by Toby Fox. He is the Younger brother of Sans the skeleton, royal guard in training, and a sentry in the town of Snowdin. Opposite to his brother, papyrus is active, loud, and full of himself; but in an endearing way. Papyrus means to become... read more
15 Vegetoid

This plant thing has made a handful of new players quit or give up.

16 Heats Flamesman Heats Flamesman is a character in the video game "Undertale." He is a fire-based monster who enjoys performing music and is often seen playing the saxophone. Heats Flamesman's quirky personality and catchy tune have made him a memorable and endearing figure within the game's diverse cast of characters... read more

He distracts people who meet him by making their brains focus on his name.

17 Annoying Dog

Toby Fox must be the worst guy in the world!

18 Toriel Toriel is a goat like monster who is the secondary major character in Toby Fox's 2016 RPG, Undertale. She saves the protagonist from Flowey and guides them through the Ruins, of which she is the self-proclaimed caretaker. She is the ex-wife of Asgore, the mother of Asriel Dreemurr, the adoptive mother... read more

Although she seems nice, she secretly hates humans. When Toriel tells the player to stay there, she has absolutely no intention of returning, leaving the player there to rot. She also refuses to help with puzzles, and despite pretending to be so protective, you still can die in her battle. (You cannot die to Papyrus.)

Very selfish and rude to humans. She doesn't care about humans at all.

19 Quacky Guy
20 River Person

Not gonna lie, River Person is kinda suspicious. The fact he knows about Gaster is a bit unsettling.

He is the only one (besides Sans) who knows Gaster! Isn't that suspicious and evil!? (Please mind my grammar.)

21 Temmie Temmie is minor character from the 2015 game Undertale made by Toby Fox. Made in the likeness of her artist, Temmie Chang, in appearance and character. Both a character and a species of monster, temmies are defined by their mix of cat and dog features, as well as their broken English. Their hidden village... read more

She's definitely hiding something behind that cute smile and improper grammar. We even caught a glimpse of her true self in the genocide route when she says, "You will regret this." A threat in proper English! Not to mention, she basically steals the money you give her for college.

Where do the Temmies even sleep or live? What is that Temmie doing in the wall, just staring at you? Why is the mushroom in so much pain? Why does nobody seem to know where they are or that they even exist? Why are they so keen on keeping their history a secret? If I were you, I'd stay away from the Temmies.

22 Napstablook Napstablook is a secondary character from Toby Fox's 2016 RPG, Undertale. He is the cousin of Mettaton, who left him in order to become famous. Due to this, poor Blooky has crippling depression.
23 Grillby

He doesn't say a word. He silently judges and manages to avoid death at the hands of the player and Chara.

24 Greater Dog
25 W. D. Gaster W . D Gaster is one of the characters from the very popular game, UnderTale . Basically, he was once the royal scientist long ago, but then was forgotten and left in the void ... read more

From what I see, people should feel bad for him. He's been stuck in the void. I'd understand if he would want to kick my ass because I'll beat him anyway. Wait... I forgot. "How can you kill something that doesn't even exist?"

I used to think Gaster was a nice dadster, but now I think otherwise. His numbers in code were all variants of 666, his followers are all afraid of him, and my headcanon is that Sans and Papyrus were his test subjects.

Honestly, he seems like he's controlling Chara to be evil, but that's just my theory.
