Top Ten Best Undertale Characters

The Top Ten

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

Nah, even though he is a funny lazybones, he is a tough battle skeleton.

BEST CHARATER OF ALL TIME! I've got a bone to pick with you if you DON'T like him!

This guy is amazing, he is so funny and made me laugh so much during undertale, but he also has a much sadder side to him, knowing about resets, timelines, and all that. I also really love how he is with papyrus, and trys to protect papyrus in the genocide route. Sans reaction to papyrus death is very real ( though we don"t get to see much of it), I would never do genocide, because thinking about what sana would have to go through, just breaks my heart. Also his theme (meglovaina) is AMAZING!

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.

He is my the 2nd top favorite character he makes me laugh, and he's kinda cute, he always protect his brother Sans The Skeleton, if you do pacifist ending papyrus care of you and miss you so much. I was so excited, even when we go through the Papyrus puzzle he doesn't give up even though we are hard on opponents he doesn't give up to be a Royal Guard he's so cool.

papyrus is AMAZING, he is really funny, and makes me laugh a lot. I find papyrus's death the saddest because even though he is on the brink of death, he still belives you can change and become a good person, papyrus has a huge heart made out of gold, and though he can be a little self absorbed, he is the BEST!

My favourite character in Undertale because he is so quirky and kind. I also love spaghetti

Papyrus is Just THE BEST His Spaghetti is fantastico and he is super nice!

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.

Undyne, Hero who tries to stop players from genocide and denying her death to do that mission

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

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.

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

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

The best
But why is this reincarnation of darkness above the true Asriel

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

three words: SAD GOAT BOI I love this guy! his story is just so SAD, and he is the only monster that doesn't get a happy ending, which is even more sad ( I also love "his theme") best song in the soundtrack in my opion.

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 smart, socially awkward, loves anime and really relatable.

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.


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

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!"

Who needs arms when ya got legs like these? *kicks you in the teeth*

mettaton has an awesome personality! he may seem like a stuck-up brat on the outside, but really, he cares about everyone!

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

Haha, Mettaton is amazing! He's really funny! And random, too. He's pretty fabulous in his EX form, but I prefer him in his normal form.

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

she's/he's just adorable and its not her/his fault the player took control of her/him she/he just wanted to be friends with everyone!

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?!

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.

In the pacifist Asgore battle, when Asgore destroys the mercy option, because he thinks he doesn't think he deserves mercy,it just breaks my heart ;-;

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!

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.

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.

*Is another character that sees the badness of players during the genocide route and help you even though she loses everyone she loves

A lot of people hate Chara because newer players who haven't played the game never looked at their dialogue where they specifically say "With your guidance I realized the true purpose of my reincarnation. Power." which means because you killed all of those people you pretty much corrupted Chara in the process. Also people may not realize it but Chara is arguably the most important character in the game. Why? Because if Asriel didn't mistake you for Chara in the true pacifist run, he probably wouldn't have stopped fighting and also because if Chara becomes evil because of your genocide run then you can never get a happy ending... Overall, Chara is an under rated character and deserves more attention.

He was good before genocide frisk(you) corrupted him. I also like that he blocks genocide frisk(you) from having a potentially fine ending by popping up & stealing your soul/destroying your world & exsistance.

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.

Temmie is cute and dreams collage. I want to see Temmie go to the collage.

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

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.

I just want to hug him. He always seems so depressed & insecure, but is pretty kind.

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.

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.

Sans: you've died 8 times, that's the number of fingers on a spider
Muffet: Bold of you to assume that my legs are fingers

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

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

Muffet is pretty meh, but I wanted to use all of my votes. She’s decent, not used for much though.

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.

Gaster Easter egg is Riverperson Is gaster and gaster with a mouth open=no hit gaster

wrong gaster should be in 1st place he's over powered god have you done any research before you even did this he can beat god and he is a god and he's not the father of sans and papyrus or anyone bet you don t have the game undertale

Gaster is so cool.He is one of the most mysterious carecters which makes him my favourite

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

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?

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

Not a character, an extra

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.

lol, look a Lesser Dog and Greater Dog. lol. Sans is AMAZING! Frisk is bootiful

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

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

Partner of the greater dog GOD

18 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.)

Never thought a shop NPC would be pretty deep. He seems like your regular adult who is stuck in an unlikeable job.

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 Greater Dog

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

Before chara destroyed the world he killed her

But, you have not pet enough!

He is the most biggest and most borkest

20 Aaron

Aaron is ready for your next flex

Remove an A and you get a Pokemon!

Aaron is pretty cool


21 Underswap Sans

Underswap Sans is so cute and should be higher on this list AND he should have his own picture!

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

I thought this was talking about the original game?

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

22 Doggo

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

Smoke dog TREATS ever day

"I am good Doggo"

Doggo is adorable

23 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!

Annoying fight, but funny character

Awesome, awesome, AWESOME!

the best

24 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.

25 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 should be higher
