Top Ten Best Undertale Characters


The Top Ten

1 Sans 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 more.

Sans is obviously fan-favorite, not only because he is hilarious in the True-Pacifist run (puns, Grillby's, MTT Resort dinner or whatever, head-dogs, etc.), but MAN, he is a complex character. He is a total beast when it comes to the Genocide-run, (keeping this kid-friendly) but it seems he has a bit of background with different elements of different topics, such as his scientific background or how he is with Papyrus, etc., and he seems like a pretty complex dude. But, if I may, he is pretty much a character that stands out from the rest. (I might get off topic) Sans is a character that just seems to have a different kind of feel to him, not only for how remarkable he is, but just how he links strongly to each story-line of the game itself. He is one of the major characters, for example, in a book or a movie you just have to question what he will do next, only to find out he did a hilarious move or something. One of the last things I wanna say is just that Sans is one of the most ...more

I really like his character. It's so complex, yet easy going. I absolutely love bad jokes, so this guy was pretty much the coolest in my book. But when I got to the genocide, I died so many times it wasn't even funny. It took me 3 months, playing over and over every day to beat him. Needless to say, I had Megolivania stuck in my head for several weeks. Even though this game is 4 years old, It is still, and always will be, the best game I have ever played. And Sans (despite the memes) is still the coolest character. And his theme is still great. I'll admit, I was super discouraged by the fandom when thinking about playing the game. And fangirls were literally everywhere, but I'm glad looked past all the toxic stuff, because this game, and this character were both really amazing. So... yeah. I also tell bad jokes left and right, and my friends love the character as well.

Sans is such a complicated character. I am totally a Sans fangirl, but that's not the only reason why I like him, just because he's popular. There's so much we know about him, and so much we don't. Toby did an excellent job creating a character with so much mystery around him. Sans seems lazy, comedic, and maybe even selfish on the outside, but really he's slightly depressed (more so depending on the route), he's serious, and he really cares about his friends. He's the weakest enemy but will give you a serious bad time. He could have also been a scientist at one point. Also, he loves bad jokes, so how much better can you get?

Sans is hilarious and he stands up for his friends and family and what he believes in. His boss fight is super hard. The hardest in the game in my opinion. That is to teach you a lesson. Also, when you do the true pacifist ending, Sans try's to help and encourage you. He also has a good taste in condiments. He is very mysterious and he can do things no other monsters can. He is also very strong willed and he's like me when it comes to being comfy and lazy. And if something even scratches his little brother Papyrus, he will destroy it. Sans has a very good taste in puns. He is such a "bonehead! "

2 Papyrus 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 more.

PAPYRUS IS THE BEST! He tought me so much about confidence, laughter, fun, love (not LOVE), and more! He is goofy, more complex than we see, and he shows us that anyone can be a good person if we just try. He is such a kind monster, and he never fails to make me smile. This game seems too real for it to be a game, the characters are too real and the plot is touching. I seem to be obsessed with Undertale, I have a little bit of a hard time with the fanbase, I always have to make sure it is labeled kid-friendly or clean. But the game is for the most part, child friendly.

I have only seen what my brother has played (he has played like 10 times and I've seen him play a lot), but this guy. THIS GUY is by far my favorite. He's so goofy, and he still believes in you even if you kill him. Plus that first few times you see him in the game are hilarious! - Qryx

It hurts to see papyrus getting killed by frisk mercilessly - Radzz202

3 Undyne Undyne Undyne is a main character in Toby Fox's 2016 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, more.

*starts screaming spear of justice*

She tasted good as sushi. - lemur


She is the best fight me if u disagree

4 Flowey (Asriel) Flowey (Asriel)

Holy HECC he is one great guy. Favorite character, I rate him infinity/10. I think I've written over five multi-paragraph essays on why he is the best character in Undertale (and also one of the best video game characters of all time). First of all, he's probably one of the most (if not THE most) important and pivotal characters in the game. Without him, there would be no beginning conflict, as there would be no Flowey or Omega Flowey. In the end, he sacrifices his own potential happiness and freedom to secure the happiness and freedom of others (and there is no way to save him). He is also the final boss of the pacifist route, which makes him pretty important if you ask me. Plus, his fight is awesome. It's something you don't really see in most games now. And his character development is amazing- it's rare that I care about a fictional character as much as I care about Asriel because somehow Toby Fox found a way to give him an un-annoying and truly tragic backstory, unlike other ...more

I just wish he could give us more friendliness pellets - lemur

I am the best flower to ever exist. (Grins like satan)

My first impression of Flowey was a psychopath who cackled with a twisted smile over tricking me to go after the 'friendliness pellets.' Everything changed when I realized he was just a child who lost compassion and his best friend. You can't help but fall in love with his complex story line!

5 Alphys 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 more.

Okay lets get this down Alphys is my number 1 favorite character, no doubt. Sure people may hate her for bothering the player during the second half of the game but honestly unlike characters like Navi from Legend of Zelda, Alphys can actually be funny and it is very realistic but I can understand why people can hate her for that. But also I like her character because she is very relate able due to her tragic past and her not knowing if she can come to terms with herself or not, its just very relate able but anyways she is my favorite character. - tacoperson

I think we give Alphys a lot less credit than she deserves. One of her lines in the quiz show basically foreshadowed the creation of Deltarune (As it was in development at this time, or at least an idea) and she also basically saves the dark world by sending the two heroes of light. Besides, she's one of the more relatable characters: She's a nerd, she uses Social Media, she lies to make people think she's cooler than she says she is, and she's socially awkward. Besides, she's LGBTQ+. How often do we see positive representation of that in video games? (Ok, well I know it's in a lot of games now, but a while ago any of the representation was either criminalized or censored)


Alphys is the most realistic character. She just wants others to like her.

6 Mettaton 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 is the best second character in Undertale for me!

7 Toriel Toriel Toriel is a main character in Toby Fox's 2016 RPG, Undertale. She is an amazing blend of goat and mother.

Basically, I absolutely love Toriel and she is BY FAR my favorite character in Undertale. And perhaps she is my favorite character from any media I have ever experienced.

I'll come forward and say I might even consider it to be an obsession (up for debate). Although I feel that it has positively affected me overall.

If you want the LONG explanation, Read on:


Toriel spoke to me (figuratively) in a way that that no other character in could. Her struggle and her backstory are things that I can relate to and sympathize with. I lost my cat to old age. And I witnessed the funeral held by a family who lost their dear son (After he had been part of their lives for over 20 years).

Toriel's situation I found to be analogous to what I experienced. I felt powerful emotions resurface when exposed to Toriel's back story.

I also adore her character. I am so drawn to her motherly nature and the loving warmth, sweetness, care and ...more

Goat Mom is my absolute favorite character other than Papyrus. She is me. I feel this connection with her unlike any other character from anything honestly. Think about it.. Who has been the most affected by this whole story? Toriel. Yet.. She has held it together. Somehow. And here you are. Her next chance at happiness with a child. But, she has to let you go.

She’s such a sweet and caring goat mama

Oh man I love goat momma and when I got to the end when I was going to fight the king when you go back to her house I almost cried my favorite character

9 Asgore 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 more.

Okay even though we don't see Asgore for 3/4 of the game and when we do his character is not fully shown but lets be honest...HE'S ADORABLE, okay sorry for sounding weird but come on, but besides that he's a pretty good character. - tacoperson

Second best - lemur

Asgore is better than a lot of the other characters in this list, both in term of personality and depth but also in his comportment and in his manner of thinking. And he decided to sacrifice a lot to help all of them.
Unlike Sans, he did had faith in you from the beginning and didn't want you to die. Which is ironic, because he is the one that had to kill you but easily the one monster that want to do it the least. He deserves a place highter than Metatton, Alphys and especially Toriel, who is arguably the character I dislike the most in this game (dude, in my second run, after I take the time to study her character, I don't hesitated to attack her all the way, and then I realized Asgore still deeply love her, and I stop right before beginning a Genocide route, by sparing her).
Which is one of the many points that make him more complex than the top 3 of this list.
What annoys me the most is without a doubt Sans's fans.
It's like any popular character's fan. They are fans ...more

Asgore is Asriel Father He great and good above Chara but Not as same level as Top 8

10 Chara 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. Her name can be changed by the player and will be assumed as the player character, until the Pacifist Route when Asriel asks for the more.

You think that you can blame your faults on Chara. That, it doesn't matter that you did a genocide run- because it was Chara's fault...Just shut up. YOU did the genocide run. They're young, impressionable...they need to be taught how to act, because they sure enough didn't live a happy life on the surface-- There's no villain in Undertale, and there doesn't have to be, unless YOU decide to take that role.

Just like when you have to sacrifice Yoshi to avoid falling in a pit in a course, that's YOU doing it, not Mario. - Pokemonfan10

I already wrote about chara in the top ten best video game characters

Chara = Characters LOL

Hmmm, lots of people wonder...
Is Chara the evil or good.
Depends on your perspective
Guess we will never know the answer...
But personally, I think shes good

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 more.

Temmie such a cuute

13 Muffet 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.

Muffet is awesome

One of a kind. No other monster in the underground like her.


I know it's weird (since she's such a minor character) but Muffet is probably my favorite character in Undertale. On the surface, she seems overly-greedy and mean, but you realize that's not the case when you look at her below the surface. All she wants is to protect her friends: the spiders. Though it may look like she's fighting you because she'll get paid to do so, but in actuality, she only attacks because she thinks you hate spiders, and she has been told that you rejoice in killing them. The moment she finds out that's not the case, she immediately forfeits the money and lets you go, going so far as to apologize for the trouble. After that, she looks at Frisk as another friend, and goes so far as to try to protect him/her from Flowey at the end of the game. Her love for her friends and selfless willingness to stand up for them makes me admire Muffet. She's like Undyne in that regard. However, the fact that it isn't as obvious as it is with Undyne, I feel, makes her a very ...more

17 Burgerpants Burgerpants Burgerpants is a vendor in the 2015 RPG video game Undertale, who sells various kinds of fast food working in MTT Resort, such as a hamburger dubbed "Glamburger", ice cream dubbed "Starfait", and even a steak in the shape of Mettaton's, his employer, face.

Bad idea. - lemur

He's just HILARIOUS. I think that he is even tied with Papyrus for the funniest character in the game. - Yendks

Burgerpants is life. Easily the realest character for me.

"I can't go to hell. I'm all out of vacation days." This sentence sums up why I love burgerpants. HUMOR

19 Asriel Dreemurr Asriel Dreemurr Asriel Dreemurr is a character from the 2015 game "Undertale". He was created by Toby Fox. more.

Asriel: I did several bad things of my own volition.
Fandom: Noo, it's okay! You're amazing!

Chara: I did one bad thing as a result of the player's actions.
Fandom: EVIL! 11

In all seriousness, Asriel is my favorite character in Undertale, and that's saying something. - TheCrystalWolf

Not the goat aghhh - lemur

Man, not only is this character sweet at heart, but I mean, his god form makes One Punch Man look like a mosquito.
The sheer fact that Asriel risked his life in the attempt to free the underground is a truly heroic thing to do...something that someone like Sans had never attempted in the game (Besides judgement, that was sorta brave)

35 Mettaton NEO Mettaton NEO

I love Mettaton Neo, for one he has an epic design (Probably my faviorate character design of all time). His theme song has amazing potential, the Ikarus Remix really did it well. But most importantantly he is the best character on the genocide run, he fights you even when he has no chance, he as far as everyone knew was the last hero of the Underground. Mettaton Neo is the reason I Mettaton is my faviorate character.

Though his epic transformation didn't stop you, the whole reasoning behind his transformation wasn't only to stop you, it was also because he wanted to be himself before he died, because he knew it was impossible to stop you...

Metteton NEO is the most coolest person and in one video you can see his transformation and I love the blaster for a hand

METTON NEO IS SO COOL! I whsh he acylay had attacks though.
