Top Ten Best Undertale Characters

The Top Ten Best Undertale Characters

1 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

Sans is the definition of awesome, amazing, funny, and epic. Sans is obviously the best character ever - MasterHand

So his puns are PUNNY yup like "we all got it down to the bone." like that pun there's many more I also like sans because he is strong and hard in genocide.

I like Papyrus but, Sans will always be forever in my heart! I love him! (Even though I love Papyrus's spaghetti)

2 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 a very nice brother to Sans. He is so confident! Love him!

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.

His personality is so charming, his theme song is really really good and overall he is a good character for Sans to share conversations and chemistry with. - PizzaMan

I LOVE papyrus he is my favorite character he holds a special place in my heart

3 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.

I just LOVE her personality and everything else about her! All time favor!

Just one of the strongest and coolest characters (papyrus is still the coolest nyeh heh heh)

I don't know I always thought of undyne as some other creature until I l, well let's just say I watched like 50 youtube videos about her and she is THE BEST CHATACTER because unlike any other video game I felt a connection with undyne. Also the name chara is hidden in the word character =)

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

4 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 used to think Flowey was Satan...until I saw that he was just poor Asriel - WitheredBonnie

Personally, asriel is just straight up a well-made character
sad yes but his story is so connectable to mine some people in my own school call me the human version of asriel. - chaddreemurr

! chara char x asriel and Tammie Tammie x closet ship I cool is Closet

5 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.


she is a summary of me (except I'm straight) but umm I just love how she is!

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

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

6 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!"

WHY!?!? METTATON aid a fan favourite he should be number one, Because Sans is overrated!

says this is a family friendly TV show when you type a swear word yet trys to murder you and also says swear words mettaton is a hypocrite - ds567

People keep talking about Sans Sans Sans, but Mettaton is also really great!

He has the coolest boss fight in neutral and pacifist, and has an amazing theme

7 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

Heh she is a very caring person and she helps out pap with his cooking he is learning how to make pizza

My favorite! I draw her at school instead of doing my work sometimes. Hehe

I love her really much. People are mean saying that she is mean to Asgore just by not willing to restart a relationship with him. They are also mean if they think that she must be kind to him even if he is the killer of her children. Yes, she abandonned her people, but it was to have the chance to save children who didn't deserved to have their soul eaten by a giant goat dad and, by saving them, she could manage to prevent the iminent war between human and monsters. She even saved asgore in the end of de pacifist! What a cool character.

8 Frisk

Frisk is very determind and is very good character.(like Chara)

Frisk is the best! She is filled with determination and also she helped save Asriel and free the monsters! But in Genocide things got rough, so I don't play the game but I know it I wish I could play but my mom doesn't let me. Welp that's it *YOUR FILLED WITH DETERMINATION*

They are the main CHARActer! (Lol I had to do that) Do I HAVE to explain?!

I look like frisk if I take my glasses off so I am now frisk now we know frisk's gender female

9 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.

you can't sit and not feel bad for Asgore, he really wants to save his people but what he has done... it sorta prevents him from doing so.

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 such a lovely character. He doesn't WANT to kill you, and isn't the 'disgusting monster' that the fandom portrays him as. He gives you every chance to go back when entering his battle-- and even though he could easily kill you in just one hit...He doesn't. He's just a big sad goat dad!

Seriously, this guy needs way more recognition. He's my favorite character in the game, just because of how sweet but powerful he is at the same time. And you never really ever get to see his true power, because you can tell he's holding back by the look on his face when the battle starts. The music is the best music in the game in my opinion, and just seriously, who could hate this guy?

10 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 actually have no idea why but I think she's the best CHARActer (sorry)

I think chara is the best character ever you guys are crazy if you put chara as the last one

Chara is great she goes to erase the world and I love she gives you a choice to join her! She should totally be in the top 3

The Contenders

11 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.

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

It's a cat.

Its cute.

What more do you want

Temmie want to go to college to all of you proud

Hunting temmie for Halloween guys you should show temmie some more love

12 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.

Napstablook is one of those characters we can all relate to. He was neglected, scared, and had anxiety, but someone chose to change that. He shows that you can over come depression, meet your goals, and be satisfied with just one piece of family. I'm surprised he's not higher. Looks like people went for the unrealistic depression who is a badass, typical.

He is just so adorable! I definitely would smooch this ghost.

He's a cute ghost with a love of music.

Napstablook fight theme is in my opinion one of the best songs in Undertale. Also, his personality is familiar to mine.

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.

She is cute and very nice and I agree with this your statement

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

I love how all the characters tend to have these deep motives for their actions, and Muffet's just like, "Give me your money."

Muffet is my favorite for many reasons 1 she just wants to reunite the spider clans if you and your family where separated what would you do you would probably do what she is doing try to reunite and the only reason she wants the money is to help out spiders

14 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.

He is cool and very mysterious I hope we get to hear more from him

Genius stong fast powerful mysterious how to sum up this guy he's so cool he could dodge till tired then he has enough hp tlo take the hits

He is so strange and yet so cool he is so unknown and that's what I love about him!

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

15 Mettaton EX

Sexy robo man

He's already on this list by the way

Mettaton EX is the best EX ever!

This is 22? seriously?

16 Grillby

Why does everyone forget Grillby? - QuarterGuysApprentice

Grillby is probably my favorite character. He should be higher.

Not a character, an extra - GGGofluckyourself

I love grillby

17 Lesser Dog Lesser Dog is a character from Undertale. He is part of the Snowdin Canine Unit, and is famous for his long neck.

Pet him to much he go's where no dog has been

Fly me to the moon. Wait. Actually. Don't. Please. - IEatPotatoes

Partner of the greater dog GOD - lemur

Pet the dog. - Puppytart

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

Asriel is one of the saddest characters in the game... but you can't hate him

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

Asriel Dreemurr babey! He definitely needs more attention and recognition. Asriel is a god both metaphorically and to my utmost delight, literally. Please get him above bone man. I refuse to let my favorite fictional character sit at #19. Not even #15, where he can at least be burger king foot lettu - ArmsOut4MrTrout

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)

19 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.

Out of all the characters in Undertale, this is the most relatable for me (and the quotes are amusing as well.)

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

Burgerpants is definitely one of the funniest characters in the game. - Garythesnail

20 Greater Dog

Strongest being ever know. Killed trillions of sans in a different timeline just by looking at them... - lemur

Before chara destroyed the world he killed her - lemur

But, you have not pet enough! - url8bit

He is the most biggest and most borkest

21 Aaron

Aaron is pretty cool

Remove an A and you get a Pokemon! - Lucas-De-Vero

Aaron is ready for your next flex - TheCrystalWolf


22 Underswap Sans

Might not be from undertale but he is sooo adorable holy crap

I thought this was talking about the original game? - Pokemonfan10

He is cute, sweet, adorable and the kindest sans ever

It's a mixture of sans and papyrus how can you not love it!

23 Doggo

I like it when he barks he's kinda cute and funny

"I am good Doggo" - Pokemonfan10

Smoke dog TREATS ever day

Doggo is adorable

24 Mad Dummy

What? Why am I so low on the list? Even people who are fanmade and not in-game are higher! Why, Why!, WHY!

Awesome, awesome, AWESOME!

Annoying fight, but funny character - SansTheComic

the best

25 Annoying Dog

Bark bark bark (dis dog is so annoying u couldn't even beat anything if dis doge is your pet lol JK)

So funny! Absorbing the orb, it's theme song, it even represents the creator of the game himself Toby Fox come on!

That dog is so much funny I really wanted that he was in the top 10 because he is so much weird and funny

His theme is really good for trolling and awesome.

26 Mad Mew Mew

She is the newest boss added in Undertale and I already love her

She is so much better than Mad Dummy

I love Mad Mew Mew in such a short time she became so popular in the fandom

She was recently added in Nintendo and I have to admit her boss fight is awesome

27 Woshua

Wosh your soul woshua

Yeah! All you people who dislike him... WOSH U SOUL!

Wosh you up. - Lucas-De-Vero

Wosh u away - Lucas-De-Vero

28 Shyren

Who doesn't love this stage-ready monster?!


29 Omega Temmie

This isn't even Undertale...

Hardest boss ever - lemur

OmEgA tEmMiE awesome

Temmie says bed time

30 Omega Flowey

Why is everybody ignoring the fact that his name is Photoshop Flowey?

I like Flowey so I like Omega Flowey too. Simple

Stop trolling it omega sans

Photoshop flowey/ flowey X. Not omega flowey - GGGofluckyourself

31 Endogeny

How is a skeleton better than a fusion of all my favorite snow puppers? It's mysterious, creepy and cute, and it's a dog,too. b a b e y

This thing is 100 puppies in 1. Who can't love him? - WarriorCatsHater

I love monster characters like this!

Why do I actually want to pet this freakish thing so much? also... WHY IS IT NOT EVEN IN THE TOP 20?!?

32 Mettaton NEO

I can't put into words how awesome this character is...


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...

33 Chairiel

This is terrible - ElSherlock

No...No...No!...NOO - Pokemonfan10

I don't know but I like it!

Choose The Chair!

34 Red

That's from Pokemon! - Lucas-De-Vero

Um... this is a fan made undertale character with her own game shes not undertale just a fan made battle - lucario_ninetales

35 Heats Flamesman

I'm Heats Flamesman! Remember my name! - TheCrystalWolf

I-I'm sorry, who? - Pokemonfan10

We should never forget his name.

Heats Flamesman is love Heats Flamesman is life. He should be a more important character. If you don't like him you should die

36 Catty

What about Bratty? - Puppytart

love her

37 Aphmau

Yup. Of course, how could I have forgotten - SansTheComic

What she look like in undertale?

Yes, Aphmau. The best Undertale character

She's not a undertake CHARActer

38 Froggit

Most controversial frog in the universe (including AUS) he MEOWs
