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.

He's not the strongest character he's just one of the hardest bosses in Undertale. And notice how I said "ONE" of the hardest bosses in Undertale meaning that there are more hard boss battles in Undertale.

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

Just because he's hard to fight doesn't mean he's the most powerful. - Terrain

So hard in Geno yet so kind in pacifist!

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.

Human nature at its worst

Chara is simply the weakest character. We don't know anything about her abilities. I don't get why people say Chara is the strongest.

Determination and insanity don't mid

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.

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

Overall Asriel Dreemurr is the most powerful character in all of Undertale.

Why you ask? Well let's start of with the fact that Flowey had consumed 6 human souls to become a being of unimaginable power. Now let's add all the monsters in the underground's souls and you have a being that has infinite attack and defense.

Asriel can use every monster in the underground against the player but not to their full extent.

Sure Sans has his gaster blasters and his powerful abilities but the people only consider him to be a hard boss. Sans would be the hardest to fight because Asriel Dreemurr is impossible to destroy.

All and all the Asriel is the most powerful character in Undertale due to having 6 souls and all the monster souls. - Terrain

Asriel is the strongest and he is the god of hyper death

HOW IS THIS THREE?! He literally has control over all of time and space!

Asriel is a prince who has a lot of power.

4 Frisk Frisk

Resetting. Need I say more?

Without question - lukemcnamara72

Sans may be insanely tough, along with Chara and Asriel, but there's one thing that makes Frisk the strongest, no matter what anyone says: resetting. -_-

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.

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.

Undyne The Undying
Literally the hardest and the most unpredictable enemy (second only to sans), still, very hard in general. Also, she is the only monster to overcome determination (Alphys did say monster soul can't contain determination, but I guess Undyne's was too strong, even stronger than death).

Spearfish should be higher up

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

So damn determined

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.

We don't know ANYTHING 'bout his abilities, too. Why is he even here.

He could be related to Sans

Watch MatPats theory on DeltaRune and this dude controls everything.

In The Game Files, Gaster Has More Health Then Asriel, Which Makes Him Most Powerful Character.

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

Flowey killed me...

Omega flowey is OP

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!

8 Annoying Dog Annoying Dog

He should be #1! he made the game!

Honestly, the strongest and most powerful Undertale character

He can kill Sans with only one script

This should be number 1

9 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!

10 Asgore Dreemurr

Actually this guy should be number 5 - kyleb79

The Newcomers

? Uranus

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 should be #3!

Ahhh so powerful!

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.

12 Omega Flowey

He is literally a god

It's so ridicolous cause this is lower than regular flowey

I voted for asriel on another device, so I’m voting on photoshop flowey. He is a powerful demigod (basically) with the power to create save points anywhere. The souls revolted only when you reminded them flowey is evil. His attacks are insane (from nukes to lazer fingers with flower heads) and very difficult to avoid. Normal flowey is a fraction of this strength, SO WHY IS HE HERE?

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.

What? her pet is so hard!

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

15 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.

For god sake guys you are wank as hell Napstablook was easily by Chara including multiple timelines and (for some reason high ball) Multiverse

Napstablook can't be killed. brooo

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

Can’t be killed

16 Mettaton NEO Mettaton NEO
17 Ultra Sans Ultra Sans

Get dunked on?!?!?

Well he isn't an Undertale character either

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!

18 Error Sans

Why does everyone say ink is stronger than Error?
They are equals

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

Can kill every thing

19 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.

Shouldn't good ol' Tem be higher on this list? I mean, the Tem shopkeeper can make the most powerful armor in the game.

TeMy dO I nEeD To sAy aNyThInG?

Bob would have been a better pick - kyleb79

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

20 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

One of the strongest! Seriously!

21 Ink Sans

I think ink is stronger then ever UA because he the god of creation

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

22 W. D. Gaster

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

23 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!

24 Mad Dummy


25 The Sassy Ruins Rock

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

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

26 Cross Chara

I thought this was undertale, not UT AU’s. But still, they have the overwrite option. Let’s see frisk come up with anything better. The only possible stronger foe is asriel, but he is already at no. 3. Show Cross some love too!

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.

27 Monster Kid Monster Kid

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


28 Whimsun

Whimsalot is the strongest it just can't be beaten

29 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

30 Froggit
31 Fell Sans

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

32 Dummy
33 Mad Mew Mew
34 Ice Cap
35 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.

36 Final Froggit

Its hard to dodge its attaks but its near mettaton too
