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.

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 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! "

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

Sans is by far the best character in the game, and the a large amount of the undertale community are in love with his personality. In pacifist he is a mocking, lazy, and somewhat flirty character. What most achknowledge is his caring and friendly traits towards the protagonist, and this is shown when he has dinner with Frisk. However, in the Genocide route, he is a mysterious, sinister individual. It is understandable as he has to live through reset after reset and watch his brother get slaughtered. Personally, I think he is absolutely fantastic.

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 so innocent and cute, and he provides some comic (sans) relief. I just find him to be the funniest characters with many layers to him. In genocide, he believes in you even if you kill him.

For me he is tied with sans, but I think Sans has enough love already. The sweetest character.

My sister used to play this game and she always said his name 24/7 - Breadwinnersislofe

Such a funny and cool character. I love him

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.

Undyne is just cool, I and her like the same things: a fair battle. She also cooked like me

Undyne touched my heart in a way that hasn't been done by any other video game character for years. Her smile, her humour, her love, and her DETERMINATION to fight for her friends, everything about her is incredible.

Smells like sushi. - Meredy

I think her whole portrayal is brilliant and realistic (not to mention her design), but the thing that I appreciated quite a lot that others sort of discard was her relationship with Alphys. Although it was sort of vague at first, you soon began to see signs of clear adoration-- the letter, commenting on her intelligence, how her dress on the date looked cute, and ESPECIALLY how she got so triggered when she saw Frisk and Alphys on the "date". I see why Alphys is basically playing the "notice me senpai" card: Undyne's truly fantastic!

I also love how much she cares about Papyrus! When she tells Frisk that he's too nice to fight and teaches him to cook spaghetti instead, I finally felt like my dreams for Undyne's inner personality were validated.

Obviously there were other characteristics about her that I revere, but you guys already covered them nicely

Undyne is so awesome. We're supposed to think she's a big villain at first, but then we find out later that she just wants to protect monsters. She's HILARIOUS in the pacifist run, and a badass in the genocide. In every single run, she's not afraid to lay down her life to save everyone else. If she isn't one of the most awesome, hilarious, and well-developed characters in Undertale, I don't know who is!

4 Flowey (Asriel) Flowey (Asriel)

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!

His twist was the best twist I've ever seen in any media, and the fastest I've been convinced that a character that seemed so sinister wasn't evil after all.

I Love Flowey because he is just awesome and looks super even Omega Flowey is cool but even MORE cooler and I like hin because he is a flower

I've always liked Flowey/Asriel. I like Flowey because I like evil character or something. And I love Asriel! The cute goat child!

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

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

I get why peple chose sans but alphys should be higher then this

She is like the female lizard version of myself. I can totally relate to her. I am always on social media annoying people, I have a crush on someone who acts as a great friend, I can't stop writing stupid fan fictions, I sometimes feel suicidal, I am always nervous around my friends and new people, I love anime, I like to get creative when I think of new things and I make A LOT of mistakes. That's why I love her so much. She is one of the most realistic characters of the game. - Daviddv0601

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

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.

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

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

Toriel is so sweet I just want to hug over and aver again

7 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!"

I don't know why I like him so much...

Best character by far, sans sucks

Why is he so low. He deserves to be in the top 5. - xdanxlei

The battle is so fun, I especially like the quiz.

*Are you a boy or a girl?
*But are you a he, or a she?
*I'm a kid!
*No. What's in your pants?

Frisk is my favorite

Much determination

I acidantly voted that sans is evil favorite undertale character here

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

For a long time sans was easily my favorite, but the amount of hate Asgore gets made me reconsider. The humans attacked them, his adopted son/daughter die, the humans killed his other son, and humans trapped all the monsters in a place underground. His actions are completely justified. He is a combination of mysterious and dark. I love it.

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

Love Asgore, so humble and compassionate. Honestly the best character by far.

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

*You realise you were the one who held the knife throughout your genocide.

She is a very strong entity. She would fare well in other games.

I can't believe Frisk stole her soul when she fell in the Ruins! All she wanted was to see the flowers from her village! - url8bit

The Contenders

11 Temmie 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 more.

She is too adorable

I love Temmie she is adorable

HOW DARE TEMMIE BE SO LOW! ;-; Temmie is obviously the best character in Undertale, people can't disagree with that. #TemIsLoveTemIsLife

She is hilarious.
Enough said.

12 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

How can you resist the fluffy boy? He's caring and a true hero. He sacrificed himself for everyone else in the Underground. Also, did I mention that Asriel is the best?

The fact that Asriel has only 2% of votes on here shows how overrated Sans is. He deserves more love than that. And I don't mean LOVE.

Asriel is the best character in Undertale. I have no idea why he isn't in the top 10. His story gives off the most feels, his boss fight is the coolest, he has infinite health, meaning that NOTHING can kill him...and he's just a sweet little boy who just wanted to FEEL again. He didn't know what he was doing as a flower. He just did what his mind told him to do. He's also a really cute character and everyone, and I mean EVERYONE wants the same thing: to SAVE Asriel. And if everyone wants to SAVE him, then why isn't HE at the top of the list?...I guess during the genocide run, people just forgot about him and forgot about who he was.

In short, Asriel is an adorable character who has the most tragic backstory that I've ever heard. He deserves more love. Not LOVE, but love. All of it.

...Don't forget the goat child. After all, he's YOUR best friend.

14 Gaster 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 . more.

Add it to the tall black and white group: Slenderman, the puppet, night nations and Gaster!

Gaster is awesome. 'enough said.

No one even knows anything about this character. Yet, he’s my favorite.

WingDings Gaster is the best UnderTale character ever, because much is unknown and there are many comics and other things that say so much about him. I recommend 'The Man Who Speaks In Hands' and 'Ask Frisk and Company".

15 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.

My favorite characters is a draw between Muffet, Sans and Napstablook.

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

Her soundtrack is such a pleasure in mind!

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

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

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)

HE'S SO GOD HE'S ON THE LIST THREE TIMES! (technically) - Pokemonfan10

He is a pretty cool character and he does have a good boss fight as well.I like this character a lot.

Azzy just wants to feel again, and he’s just a broken child underneath all those delta runes. His battle theme is, in my opinion, the absolute best, and it creates this feeling even beyond the finality of Asgore. Sans fangirls, watch out for this bad boy!

33 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.


I think he is a good meme why don't most people like him he's SO CUTE that's just my opinion though
