Top 10 Strongest 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.

Alright Sans is definitely the hardest boss. He also the weakest, but since the protagonist chose genocide, he become the strongest. He was a complete counter to the protagonist making it almost impossible for us to even hit him. His knowledge and speed make it practically a curb stomp. Sans is by far the strongest character, the best counter to the protagonist.

Sans IS stronger than Chara. Chara, when possessing Frisk during a Genocide Route, can only beat him after dying to him countless times and memorizing his attack patterns. Sure, the Fallen Human can destroy the world, steal souls and take possession of other living humans' bodies, but if they somehow came back to life and faced Sans head-on, the fan-favorite skeleton would still win. - Yendks

I'm only voting here because I wanted to say something. This isn't about "Favourite characters". It's about the strongest character. Sans isn't the strongest, example, Frisk/us/Chara can whitsand death determination (i'm not talking about the resets). If you're talking about how he has the Kr/Karma ability, it doesn't matter. He may be difficult but that's different from strength. His karma ability makes it so that his bones don't disappear and makes it so you get poison. Chara Literally killed your game with 230+ 9's... Though... We are able to hack the game, so can Toby...

Thank you very much for this much needed comment. I've seen several karma and favorite votes. I personally voted for Chara. - Darktail_of_FireClan

Definitely the hardest boss. He is like one punch man except he can't kill you in one hit. It may say on stats that he only has "1 attack and 1 defense, the easiest enemy. can't keep dodging forever, keep attacking." Well hoho they are wrong there. He uses his magic in such a way where his "1 damage" keeps attacking you as long as you are at a place where you take damage. Its sort of like poison. And yes, he dodges your attacks. He is the only one WHO can do that. You literally have to memorize his attacks. The only way you can attack him is when he uses his special attack witch is literally nothing. He gets so tired he falls asleep. After he does, start moving your soul to the left and the box will start moving. After its above the fight button, start moving it down, and attack. He will dodge the first time, but you will slash at him again and this time, it hits! He starts bleeding from the stomach, and mouth and starts moving to the side saying he is going to ...more

2 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.

Statistically. Completing a Geno makes Chara the "player" of the game as they take your soul. The player killed Sans and can do again if they want. If Chara=Player then Chara is stronger then Sans but only after a Geno.

Chara is quite a strong character. They were able to kill sans and everyone else in the underground. They were even able to erased their entire game and not get affected by it.

Chara ends up dying in the end anyway so what is the point of putting her in second place?

Has corruptted the game no one can top that except annyoing dog impossible to kill only annoying dog can kill it - kyleb79

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

Chara and Asriel would basically have an endless battle. they could not beat each other. I give the edge to Asriel though. Like the Player, Chara can reset. She is pure evil so she could not beat Asriel. Asriel could kill Chara but she would reset, but due to the fact that Asriel can kill her, I give him the edge and the title of most powerful character. - Bswaggers

Asriel has sans soul, so how can sans be stronger?

I'm sorry, but asriel beats everyone. He has infinite health and does infinite damage, and all his attacks are OP.

If Asriel Dreemurr is technically stronger than Sans cause he took the Six human souls and all monster souls including Sans.He became the GOD OF HYPERDEATH and he has infinite Attack,HP and defense so he has to be stronger than Sans.

4 Frisk Frisk

Frisk can be killed and often is killed but Frisk never truly dies, they just come back and try again over, and over. Frisk can RESET EVERYTHING, so Sans stands no chance, Chara can only ERASE the world with Frisk's guidence and Asriel does not seem to have full power over the timeline as if so, why wouldn't he just RESET instantly? He has to kill Frisk over and over to make everyone forget Frisk before he can!

Before someone hates me, this is my opinion and all of the characters above Frisk have their own reasons which are completely valid I am just showing my opinion.

Frisk should be number 1 not sans. You the human can defeat sans. The human can defeat anyone. You can spare and fight.

I think Frisk would be the strongest because the human has a chance to win any battle that comes

Sans only for Dumb Retard
Frisk Beats a 100000000000000000 Monsters in Undertale
How about Sans the Overrated Skeleton?
He do just 1 damage
Wuw 1 Damage can beat anything, That’s Rerarded

5 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.

She too can use determination, that was the burning feeling she couldn't describe, and no matter what run you are doing, if you ever get her life to zero, she refills it.

Em... Also she WANTS a fair battle...
And if you didn't dodge the first bullet on purpose lots of times, she will fed up and her attacks will be impossible to avoid

Undyne. She has got determination, spear, and she is my favourite. Normal Undyne is strong, but Undyne the Undying is much stronger!

Spearfish should be higher up

6 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.

Three words-Gaster Blaster Master! - buttersock

Canon:? Fanon: OP, Void-torn god - Chara

He should be number 2

This guy is way better than sans sans has gaster blaster this guy CREATED gaster blaster how is a friggen lazzy as he** skeleton BETTER THAN the GUY WHO CREATED HIS STRONGEST ATTACK?!

7 Flowey Flowey Flowey is a flower in the RPG Undertale. He is the first character you meet, and also your best friend.

Why so low, let's not forget that in geno run Flowey mentions she(i know she's a boy but I always imagined and always will imagine her as a girl) lived through if not thousands of timelines, in some she was nice in some she slaughtered everybody, but she also says she never got to even touch the six souls, so she murdered EVERYBODY without being Omega Flowey, also her "friendliness pellets" bring you down to JUST 1 HP, wich NO characters do!

Omega flowey is OP


She is unkillable, as she is able to go back to her ‘savepoint’, wich she even prevented from frisk to do in the omega fight. Plus she could’ve killed all your friends, if she didn’t want to see you flipping crying behind your monitor, because she even knows it's a videogame.

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

She is my sister

She is so kind, her kindness would blow ALL THE EVIL OUT OF THE FRIKIN ATMOSPHERE!

9 Annoying Dog Annoying Dog

He created the game. End of story.

He strongest Undertale character

Made the game he can edit it delete any characters, its in the thumbnail. Period.

10 Asgore Dreemurr

Actually this guy should be number 5 - kyleb79

The Contenders

11 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!"

He is stronger than Undyne because of 3 reasons. 1 He can dance on you and make you have to dodge tons of legs. 2. He has mini versions of himself to help protect him. 3. His standard form is indestructible and his EX form has lots of tricks like bombs thrown at you... legs kicked at you... mini mettatons thrown at you... and even his own power source. I think Undyne is strong... but Mettaton is slightly stronger. I think she should go here and Mettaton should go at number 8. Asgore would go to 7.

I resemble metaton ex to the point were its scary, we're both so FABUlOUS

Ahhh so powerful!

sooo cool

12 Omega Flowey

Easy choice

13 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.

You know he has attack 8 one more then undyne. Which is strange...

14 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.

She one shots me every time... End of story

What? her pet is so hard!

15 Mettaton NEO Mettaton NEO
16 Napstablook 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 the only character in undertale that can not die by chara or anything

He just lowered his health because he's nice. You can't really kill him

Napstablook can't be killed. brooo

17 Ultra Sans Ultra Sans

Hey it's cool to have a cool character in the game. Besides the title says Top 10 Strongest Undertale Characters not Top 10 Strongest Undertale Characters From the Game.

Who put Ultra Sans here? He isn't even a character in the game!

Well he isn't an Undertale character either

He mest be in the to 10

18 Error Sans

Sans has strings that can take souls but he's not strong enough to kill ink sans

Can kill every thing

19 Jerry

Sans is tough. Jerry is the hardest boss in the history of gaming and makes all other bosses look easy. Sorry Sans, but you didn't make me rage quit 100 times then quit Undertale. I came back 2 weeks later and cannot get past Ruins Dummy.

One Punch Man's worst enemy. Too strong and can take on all of Undertale's characters at once and beat them. With its eyes closed. Without moving.

Sans can make him crap

I agree! Jerry can one shot goku, superman, chara, he needs to be nerfed right now! - Chara

20 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.

Bob would have been a better pick - kyleb79

TeMy dO I nEeD To sAy aNyThInG?

Tem is no power, tems power is cootness, Annoying Doggo Is Second.

TEmY iS poWerFuL

21 W. D. Gaster

Gaster is so strong he can only be fought in a cheat code, then again he has almost never been beat.

22 Dusttale Sans

Hey bud Dusttale Sans is from an AU not Undertale who put dis here

Dusttale sans is the best. End of.

(spoilers) He is basically a genocide version of sans after 372 genocide routes. also, anyone who voted or made flowery in the top ten, he's a murderous lunatic, HE EVEN KILLS HIS OWN BROTHER, PEOPLE!

Sans would never over 100 trillion pounds kill his brother.The ONLY people who could beat him is chara, asrial and the Annoying Dog.


When you encounter him in the secret cave thing, he says "I don't have enough..." this means he's a murder and a lunatic, bloodthirsty for EXP (Execution points) and LOVE (Level of Violence).

One of his attacks is a red, spinning bone wheel. After 4 seconds, the whole box goes red.It doesn't hurt you, BUT THE BONE WHEEL IS STILL SPINNING, YOU "MAD DUMMIES."

please vote if you agree after this statement, thank you!

23 The Sassy Ruins Rock

If it showed its true power, it would be the 2nd strongest thing in Undertale, only Jerry is more powerful.

Be glad this absolute unit wasn’t getting serious with you

24 Ink Sans

Ink sans is strong enough to go to different universes and strong than error sans

Ink Sans should be #1. First of all, he created every AU, and secondly, he protects them and he is able to draw whatever he wants and make it come to life. Ink is easily the strongest. - Sans_The_Skeleton

Draws The AU's

25 Mad Dummy
26 Whimsun

Whimsalot is the strongest it just can't be beaten

27 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.

He has created Mettaton give him time for more powerful monsters. ps he made undyne so powerful

28 Froggit
29 Cross Chara

Bro.Chara would just slay away at everyone.She has a knife almost as big as him/her.She can also just take control of anyone,ANYONE.

30 Dummy
31 Monster Kid Monster Kid

This mans stood in your way even when he knew you were demolishing him in genocide
he deserves an oscar.


32 Mad Mew Mew
33 Alphys NEO Alphys NEO

She is considered to be the most difficult enemy.She is harder than Mettaton NEO whose does absolutely nothing but instantly takes between 900,000 and 999,999 damage.
Alphys uses Mettaton's attacks and uses yellow mode... She also uses straight beam projectiles that emerge from skeletal faces, known as " Gaster Blasters."
When she loses all of her hp, she resumes the battle after gaining determination. As the fight progresses she continues to melt along with deteriorating the music with her fast forward and rewind. after surviving the phase, she stands there to finally be taken out.

34 Final Froggit

Its hard to dodge its attaks but its near mettaton too

35 Fell Sans

Fell sans will do nothing not to kill I mean his motto is KILL OR BE KILLED
