Top 10 Best Undertale Characters

When it comes to Undertale, few things stand out more than the unforgettable characters that populate its world. From the moment you step into the underground, you're surrounded by personalities that are funny, emotional, and often surprising. Each character brings something unique to the table, whether it's through their story arc, combat style, or the quirky dialogue that has made this game a fan favorite.

This list of the best Undertale characters is a celebration of those personalities that have stuck with players long after they've finished the game. Maybe you have a soft spot for a certain skeleton with a penchant for bad puns, or perhaps you're more into the high-energy, show-stopping style of a certain robot. Whatever your preferences, this is your chance to see how your favorites stack up against those of other fans.
The Top Ten
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

Sans obviously had to be number one. He is definitely a fan favorite. His personality, humor, and even puns are loved by all.

Also (spoilers if you do not know), his genocide battle is extremely difficult. His flashing eye, smile, and wink catch people's attention and make them smile or laugh.

He is also very mysterious. He looks nothing like his brother Papyrus, who is in the number two spot. When you kill him in the genocide route, he bleeds like a normal human. He also winks, like I mentioned before, but a skeleton would not be able to wink. The only possible explanation would be a mask, but masks cannot wink either.

It gets stranger. When Sans talks, his mouth does not move. Anyway, we are getting off track. My point is that Sans is, without a doubt, always going to be number one.

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

Papyrus may act like a dork, but that's the reason why I love him! It's kind of adorable and hilarious to see him behave like that. He's such a big sweetheart, too, he just doesn't like to show it.

Also, I'll be honest, he's quite relatable. That moment when you feel like a useless being, wanting to have friends but having none, is something I've experienced. I had depression due to those things. What I admire about Papyrus is that he stays positive and he knows there are still good things in his life. I don't care if Sans is cool, popular, powerful, edgy, or funny. Papyrus will always be my favorite.

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

Undyne is confident, incredibly strong, a bit cocky, and most importantly, a true heroine.

After chasing you for ages, appearing like an ominous clanking metal tower, you discover during the pacifist run that she's a jerk with a heart of gold. Making friends with her and helping her get together with Alphys are two of the highlights of the game. In the genocide run, however, she becomes Undyne the Undying, a badass filled with determination to save her friends and the Underground from you, the real monster. Her death, and she does not die easily, is the most tragic in the Genocide run.

Basically, she's a fantastic character. She's no Mary Sue.

Flowey (Asriel)

Asriel is the best character in Undertale. I have no idea why he isn't in the top 10. His story is the most touching, his boss fight is the coolest, and he has infinite health, meaning that nothing can kill him. He's just a sweet little boy who wanted to feel again. He didn't understand his actions as a flower. He simply followed his instincts. He's also a really cute character, and everyone, and I mean everyone, wants the same thing: to SAVE Asriel. If everyone wants to save him, why isn't he at the top of the list? Perhaps during the genocide run, people forgot about him and who he was.

In short, Asriel is an adorable character with the most tragic backstory 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.

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 love Mettaton for many reasons.

1. He is incredibly hilarious. I love when he "sings" in the musical or randomly turns into a humanoid robot with awesome legs!

2. He is consistently funny. Try to think of a moment that completely stands out in hilarity. Hmm... you have the quiz show, the cooking show, the musical, and when he turns into Mettaton EX. Wait, that's every funny moment!

3. Though he appears to be a selfish jerk, he is only doing "evil" things for Alphys. He reunites with his cousin at the end of the true pacifist route. He only attempts to take your soul to save humanity from Asgore (and fulfill his lifelong dream) but realizes that he is an incredibly important character for the underground, as so many people would be depressed if he were gone.

4. He is also very important to the story. If he were never made, Alphys would never have become the royal scientist and Flowey would never have been created, therefore stopping the true pacifist or any ending from working.

These are the main reasons I love Mettaton. Sorry if I rambled on for a long time, but I hope that others agree with me!

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

Okay, let's get this down. Alphys is my number one favorite character, no doubt. Sure, people may dislike 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 dislike her for that.

Also, I like her character because she is very relatable due to her tragic past and her not knowing if she can come to terms with herself or not. It's just very relatable. But anyway, she is my favorite character.

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

Toriel is an amazing, well-written character. She is the tutorial character of Undertale, of course, and she assists you with the game, unlike Flowey, the supposed tutorial character.

Throughout your journey in the ruins, you come to love her, but her flaws become apparent at the end of the ruins where you must fight her to leave. Playing normally, you might think Undertale is a regular RPG that relies on killing enemies to proceed, but this is not the case at all, and you may end up killing a character you learned to love.

Overall, Goat Mom is simply the best.

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

Asgore is so underrated. He is the greatest and most complex character in all of Undertale. Sans knows how to hack life itself and prefers to sell hot dogs and threaten Frisk. Papyrus is naive, yet managed to get a literal god to protect him. Undyne is a fish warrior who struggles at her job. Alphys is a scientist who did cruel things in the name of science. And Toriel left her husband because she loves children and never broke the barrier until it was the seventh child that Asgore needed to open the gate. Asgore, on the other hand, was a father who held no grudge against humans for trapping them underground and also adopted a random child that fell into the mountain. When both of his children died, instead of succumbing to despair, he chose to take action. And he is the bad guy because adults and those in charge are often portrayed negatively.

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.

Frisk is the main character but even though we all know them and think that they're good, I mean they are, but think about it, they're kind of heroic in a way. If you've played UNDERTALE, you know what I mean. Chara and Frisk are trying to save the Underground. They both have no reason for any hate alongside any UNDERTALE character.

It's the main character. Some people believe that you only truly play as Frisk in pacifist mode, but I believe in genocide mode it's just an influence from Chara, and we are always Frisk. We just choose what we think.

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

A lot of people dislike Chara because newer players who haven't experienced the game often overlook their dialogue. Chara specifically says, "With your guidance, I realized the true purpose of my reincarnation. Power." This indicates that by killing all those characters, you essentially corrupted Chara. Additionally, many may not realize that Chara is arguably the most important character in the game. Why? Because if Asriel didn't mistake you for Chara during the true pacifist run, he probably wouldn't have stopped fighting. Moreover, if Chara becomes evil due to your actions in the genocide run, you can never achieve a happy ending. Overall, Chara is an underrated character and deserves more recognition.

The Newcomers

? River Person
? Final Froggit

A non-boss monster found in the CORE. He knows exactly why it's here.

The Contenders
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... read more

Temmie is funny, cats and dogs are my favorite animals, and she is the only vendor you can sell to. Also, she has Temmie armor, the best pacifist armor.

What, why isn't Temmie number 10 or lower? Mettaton is just liked for "dem legs," but you can actually buy and sell with the adorable character Temmie. Hopefully, people vote for Tem! #Tem2016

Temmie is the best! They are based off an artist and they are funny, happy, and derpy. If you are looking for a cosplay then I would recommend this fun and loved Undertale character. However, the cosplay may take a lot of hard work, hardship, and attention. I am working on my Temmie cosplay outfit right now!

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 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 that's not the case once you delve deeper. All she wants is to protect her friends: the spiders.

Though it may appear that she's fighting you because she'll get paid, in reality, she only attacks because she thinks you hate spiders and have been told that you rejoice in killing them. The moment she discovers that's not true, she immediately forfeits the money and lets you go, even apologizing for the trouble. Afterward, she views Frisk as another friend and even tries to protect him or 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, her subtle qualities make her a very interesting character.

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.

When I first saw Napstablook, my heart exploded into millions of tiny pieces. Blooky was a character I could relate to, with their feelings and emotions, their love for music, and their introverted nature. There is no reason why you shouldn't cherish this lovable ghost. They are courteous to others, do not want to waste your time, and even Blooky's themes (yes, even Ghouliday) are, in my ultimate opinion, amazing.

It is a shame we do not see Blooky often in the game, but they are a character I will always return to because of the amazing features that make them unique. So, at the end of the day, with the question asked, heck yes. I would definitely kiss that ghost.

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

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'.

A true mystery of a character never to be revealed. The first Royal Scientist, a figure who was erased from the timeline when he fell into his creation. Perhaps I should stop there, I needn't gossip about someone who's listening and watching.

Gaster is by far one of the most mysterious and interesting characters in Undertale. He is a mystery and is very mysterious.

Greater Dog

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

A dog that's greater than Lesser Dog must mean he's better and cooler somehow.

Listen to "Dog Song," and you will understand.

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.

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

"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.

Annoying Dog

He is literally Toby Fox! He is honestly a god and he is never annoying. He is always funny. I always love seeing him pop up even if he is a bomb.

So funny! Absorbing the orb, its theme song, it even represents the creator of the game himself, Toby Fox. Come on!

Super funny and cute, but I still don't know what it did to the legendary artifact.

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

Fly me to the moon. Wait. Actually, don't. Please.

I spent forever petting him. It was great.

Grillby

Ah, the chill bartender. He really should get his own theme or be a bigger character. He must not want it, though. He really wants Sans to pay his tab then.

He's hot. He's a bartender. He's patient with Sans and his tab. And he has a lovely supposed niece.

Grillby said he would get you a glass of water but doesn't touch the stuff.

Mad Mew Mew

Mad Mew Mew is a really underrated character. She has a great design, a great story, and basically an anime around her.

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

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

Aaron

Remove an A, and you get a Pokémon!

Mad Dummy

The Mad Dummy is such a weird pick, but a cool character nonetheless. I wish it was more utilized than just one (or two depending on what you play on) mini-boss.

The music is very catchy, and the fight is funny. Why is he rated so low?

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

Doggo
Woshua

Everybody's favorite germaphobic turtle! Who can say no to that face?

Shyren

Shyren is my favorite common enemy in the game, even though they're only found in literally one room. They have so much more character than all the other monsters.

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