Top 10 Cutest Characters in Undertale

It's wild how a game that lets you spare or obliterate monsters can also make you want to wrap them up in a fuzzy blanket and protect them forever. Undertale isn't just about boss fights and moral dilemmas. It's packed with characters so cute they make your heart go aww just looking at them.

From goofy smiles and awkward dance moves to nervous stammers and absolute chaos in a tiny dog body, this game has an all-star lineup of adorableness.

Some of them are sweet. Some are weird. Some are total chaos goblins. And yet they all manage to make you go aww or at least crack a smile.

It's not always about the big sad eyes or the cutesy voice either. Sometimes it's the way they talk, the things they say, or the way they just stand there awkwardly in a corner hoping you'll notice them. It's the kind of charm that sneaks up on you while you're busy dodging death.

Scroll through, click the heart-thieves that speak to your soul. Just try not to fall into the temptation of petting the screen. Some of them bite. Or explode. Or steal your wallet. It's Undertale, after all.

The Top Ten

Temmie

Temmie is a minor character from the 2015 game Undertale, created by Toby Fox. She is based on artist Temmie Chang, both in appearance and personality. A mix of cat and dog traits, temmies speak in broken English and live in Temmie Village, which contains the only shop where players can sell items. This... read more

She is SO adorable, especially when she winks at you when you buy something.

Hoi! She is one of my favorite characters. Can you say no to that face?

Temmie is so cute and says Hoi! She is a hidden part in Undertale. Did I say... CUUUTTTE?!?!
Asriel Dreemurr

Asriel Dreemurr is a character in the 2015 video game Undertale, created by Toby Fox.
He is the biological child of King Asgore Dreemurr and Queen Toriel, but he was believed to have died before the game's events. In the True Pacifist Route, where the player spares every character, Asriel's backstory... read more

I honestly just really like his character, and I feel bad for him. His backstory is sad, and he deserves more in the game than just being the final boss.

I actually own a bunch of goats, so I may be biased here, but young goats are adorable. They have little floppy ears, big old eyes, and sometimes their tongues stick out for no reason. Goats, Asriel included, are adorable.

I wish most in Undertale to save Asriel. I feel so, so bad for him. He never deserved to die and face such a horrible fate. I wish I could squish his paw again. I was completely numb from all the emotions I felt during the Asriel part. I'm never doing any other route than True Pacifist, and I'm not even going to reset.

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 serves as a supporting protagonist in the "Pacifist" and "Neutral" routes of the game, and a heroic antagonist and final boss in the "Genocide" route. Sans is known for his... read more

I just love the way Sans looks with his hoodie and the way he's always making cheesy puns. They nailed his character, in my opinion!

He's not cute, but he's a pretty cool dude, and he's pretty much my favorite character from the game, other than Temmie. Though she is adorable!

And cue the fangirls squealing with delight to talk about this subject.
Alphys

Alphys is a lab-coat-wearing, bespectacled, yellow-skinned lizard scientist who resides in her lab in Hotland in the critically acclaimed RPG Undertale. She watches large amounts of anime and is responsible for major plot developments, including the creation of the robot Mettaton. Alphys also harbors... read more

Personality-wise, I think Alphys should probably be #1, personally.
On a semi-related side note, Alphys' Bad School Day (and quite a bit of my other Alphys-related stuff) is hilarious as well.
And let's not forget I See Alphys, I See Francis...

I think she should be number one. I saw this picture of her on another list, and I decided to watch an Undertale playthrough just so I could see her. She is cute.

Also one of the funniest. "Kissy Cutie Mew Mew 2 isn't kissy or cutie. It's trash!"
Napstablook

Napstablook is a secondary character from Toby Fox's 2015 RPG Undertale. He is a melancholic ghost and the cousin of Mettaton, who left to pursue fame. Napstablook is characterized by his low self-esteem and depressive personality, often staying at home and enjoying music.

As soon as I first met Napstablook, I loved him. He just looks so lonely, and it makes you want to hug him. The music in his fight, though, is almost too awesome.

OK, Sans is my favorite character, but Napstablook should really be ranked higher than him.

Napstablook is the sweetest character because he is so shy and gentle, and it's just too cute! Especially when he wears his hat! So kawaii!
Papyrus

Papyrus is a character from the 2015 game Undertale, created by Toby Fox. He is the younger brother of Sans the Skeleton, a Royal Guard in training, and a sentry in the town of Snowdin. Unlike his brother, Papyrus is energetic, loud, and somewhat full of himself, but in an endearing and earnest way.... read more

He's cute in his innocence, not his appearance. Visually, he's not cute. But his view of people and the world around him is adorable. Paps is a good little bean, and anyone who kills him deserves to have a bad time.

Papyrus is so cute. He is Sans' bro, which only makes him cuter when he scolds him. He still believes in you after you kill him on the genocide route. That makes him even cuter in a way. And do I even have to say this? NEH HE HEH!

Papyrus is the cutest, coolest, best, nicest, purest, and overall amazing!
Toriel

Toriel is a goat-like monster who is a secondary major character in Toby Fox's 2015 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

She is very caring for Frisk. She wants to protect Frisk at all costs, and her design is, in my opinion, perfect for the game as a character who has gone through a lot.

The first character in the game to be made into an official plushie. Enough said. (Still, though, there really should be an Alphys one.)
Annoying Dog

This dog is so cute. How could I say no to him? I've seen many cute dogs in Undertale, but he is just way too adorable!

I'm sorry, I just have to give it to you, Annoying Dog. You're way too cute! Why aren't you higher on the list?

Another who should be ranked higher than Sans. I mean, look at his face! It's adorable!
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 only television star in the Underground. Mettaton is a popular character within the fanbase, known for his flamboyant personality and dramatic flair. His notable features include... read more

I'm not a girl, and I have a crush on Mettaton.
I'm.
Gay.
For.
Mettaton.
Frisk

Frisk is the main protagonist in the 2015 RPG Undertale, created by Toby Fox. They are the eighth human to fall into the Underground and serve as the player's character throughout the game. Frisk's name is only revealed at the end of the True Pacifist Route.

She is not Dora because Dora is dumb and ugly, and Frisk is literally the cutest little girl in that game. The part where she hugs Asriel in the True Pacifist route is completely wholesome and the exact opposite of heartbreaking. I died of cuteness.

Just imagine a small human. Now imagine this small human petting random dog guards to become friends. Adorable, right?

Okay, to the person who said that Frisk's eyes are closed, they're not. Their eyes are just very small. Wait, you call their eyes eyebrows?

The Contenders

Muffet

Muffet is a character from the game Undertale. She appears in the Hotland area, where she runs a bake sale to raise funds for the spider clan. Her goal is to help reunite the spiders from the Ruins with those in Hotland, as they cannot cross the Snowdin region.

I like her because she is not keeping money for greed. She is simply helping the spiders in the ruins to rent a heated limo so they can go back with Muffet in Hotland. It's so cute that she put the effort into making a bake sale for the spiders in the ruins.

Muffet is absolutely adorable with her somewhat elegant appearance, tiny little fangs, and pigtails. I just want to hug her and forget about the world's troubles.

Not many people realize that Muffet is, in fact, rather cute. Probably because they were too busy raging because Muffet kept making them spend their cash.
Lesser Dog

Lesser Dog is a character from the indie video game Undertale. He is a member of the Snowdin Canine Unit and becomes increasingly enthusiastic when the player chooses to pet him. As the encounter continues, his neck stretches longer and longer, creating a humorous and memorable experience for players... read more

Once again, should be ranked higher than Sans. Lesser Dog is adorable!

Cuter. Take everything from Greater Dog and double it!

I don't know him, but I heard he is cute.
Greater Dog

If it is one of the greatest beings in the world (cats and dogs), then it is automatically cute. How is Sans cuter than two dogs and two goats?

It's a dog. Do I need to say anything else?

I don't know him, but I heard he is cute.
Chara

Chara is a character in the game Undertale by Toby Fox and is one of the seven humans to fall into the Underground before the protagonist. The name Chara is chosen by the player at the start, though it is later revealed that this name actually belongs to the first fallen human. During the Genocide Route... read more

Asriel: I did a lot of bad things of my own volition.
Fandom: No, it's fine! It wasn't your fault, you're amazing!
Chara: I did one bad thing as a result of the player's actions.
Fandom: EVIL!

Asriel: I did a lot of bad things of my own volition.
Fandom: No, it's okay! It wasn't your fault, you're amazing!
Chara: I did one bad thing as a result of the player's actions.
Fandom: EVIL!

Despite being clearly "evil," they are adorably rosy-cheeked and smiling.
Flowey

Flowey is a character in the RPG Undertale. He is the first character you encounter and initially presents himself as your friend. However, his true nature as a manipulative antagonist is soon revealed as the game progresses.

Flowey's actually really cute! Well, when you see him first. Not when you know he's ready to kill you.
Burgerpants

Burgerpants is a vendor in the 2015 RPG Undertale who works at the MTT Resort. He sells fast food items like the "Glamburger," "Starfait," and a steak shaped like Mettaton's face. Burgerpants is known for his jaded attitude and humorous dialogue about his job and life.

Am I the only one who thought he was a bear?

He is a cat. Who doesn't like cats?
Monster Kid

Yo! I kinda think Temmie is the cutest character, but Monster Kid is adorable! He's like a stegosaurus Yoshi. His face-falling animation is the cutest thing about him! Monster Kid would be #2 on my list!

Yo! Monster Kid is like a Yoshi that talks and falls down all the time. Just the cutest monster possible, especially with the Undyne obsession. Yo! Monster Kid is so cool!

Yes! He falls on his face all the time.
Omega Flowey

What do you mean he's scary? He's cute!
Asgore

Asgore Dreemurr is a boss monster and the king of the monsters in the 2015 RPG Undertale, created by Toby Fox. Asgore is portrayed as the main antagonist, with a plan to collect seven human souls to break the barrier trapping the monsters underground. His character is slowly revealed through hints and... read more

Light is shining through the barrier.
It seems like your adventure is almost over.
You're filled with determination! I love this bit when you meet Asgore.

I want to stay with Asgore.
"Would you like a cup of tea?"
Heck yeah!
Endogeny

Endogeny is a minor character from the indie game Undertale, which was developed by Toby Fox. It is one of the "Amalgamates," a group of monsters that have been fused together as a result of unethical experiments.
This creature appears as a disturbing blend of several dogs and is encountered in... read more

I hope this creature exists in the real world. Imagine it panting like a real dog and wagging its tail while emitting many distorted barks. It would probably take over my whole kitchen, but it would be worth it to keep as a pet. Even with its flesh and fur dripping everywhere, washers and dryers exist, so it would definitely be worth it. Long live this cute doggo!

I personally find him cute, but I also find snakes and jumping spiders cute (as long as they don't touch me).
Onionsan
Gaster

W. D. Gaster is a mysterious character from the game Undertale. He was once the Royal Scientist before Alphys, but was erased from existence after a lab experiment went wrong. Though not directly encountered in the game, Gaster's presence is hinted at through cryptic messages and rare NPC encounters... read more

Poor Gaster. You should know what he is going through, being forced to watch a world in which he doesn't exist, with few people having knowledge of his existence.
"I can't imagine what Doctor Gaster must be going through."
"Beware of the man who speaks in hands."
"Although he should be gone, he's still there."
Vulkin
Undyne

Undyne is a main character in Toby Fox's 2015 RPG Undertale. She is the fish-like, armor-clad captain of the Royal Guard, devoted to protecting the monsters of the Underground. Her name is a pun on the word "Undying" and a reference to the mythical water spirit, "Undine."... read more

I'm not sure if I'm the annoying dog or Undyne. Injustice makes me mad, and I want to keep everyone alive from a genocidal maniac.
WHO'S WITH ME!? This world, it will live on...
