Top 10 Strongest 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, in my opinion, is basically the hardest boss to encounter in the game. Before skipping this, I have something to say. Yes, sure, True Pacifist bosses are really strong (Omega Flowey and Asriel Dreemurr, for example), and Chara can basically kill you anytime they want, but in game, Sans is the hardest in all means. In Omega Flowey's fight, you have checkpoints, with the help of the 6 souls. Asriel Dreemurr's fight basically blocks inevitable deaths, meaning you cannot die. Sans' fight doesn't do that. There are no checkpoints/no-death policies in his fight. Although Sans is basically the weakest character in-game (less than Monster Kid), he uses Karmic Retribution (or whatever it's called) and basically poisons you throughout his fight, bringing a bit more stress to the player, even in the menu you're not safe from his attacks, with you still getting KR damage (I'm going off-topic here) which NO other boss fight does. Honestly, I'll keep this brief. Although Chara is the true #1, ...more

Sans is much more powerful than asriel, due to him being the only character that doesn't the standard fight mechanics(other than photoshop flowey). Combining that with the fact that he doesn't give you invincibilty after being hit, and deals karma damage makes him the most powerful character in all of undertale. I know this because I have played bad time simulator.

Gaster blasters, bones, the only monster that can doge and most importantly KARMA he uses this when he fights chara in geocide this is KR and when you get hit you take more damage because that is your sins attacking you. But only has 1 HP

His Karma ability is an ability that he alone has because of the fact that he is the punisher, not some guardian or something. Karma, as an ability, gives him the ability to attack a person with their sins or LV in this case, And that's not all he also has the ability to stop Time...

Am I the only one who knew that?

2 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. Their 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.

Cute and strong; the whole package. I'm someone that thinks Chara is a good person so I think that they decided to unleash their power to kill you in the end of a geno route

can erase the world and to add on, she is a demon in a body, making her twice as strong. This is because she says that she is the demon in the player' soul and she wants to get rid of the world( Earth and the underworld). So all in all, Chars is the strongest character in undertale.

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.

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

Simply because of his infinite defense, attack, and health, he simply is EASILY the most powerful Undertale character, that is, unless you include the annoying dog. Asriel Dreemurr was NOT defeated because of your own determination, he was defeated because he started to FEEL again, and then stopped. Yes, he isn't the HARDEST boss, sans is, but Asriel is CLEARLY the strongest character considering his stats. You can even play the actual game to realize he has these stats. Ofc, his infinite attack might've been not used to it's full potential considering Asriel says he was only using a portion of his power during the fight, and then uses his god of hyperdeath form 100 %. Yes, it doesn't do inf attack like the stats said, but it has to be possible, so Toby probably just did that for the game's purpose.

Asriel has the power of all monster and human souls, making him quite literally a god. Sans is the weakest enemy, and the only reason he even does slight damage is due to karma and for some reason I frame removal. If we're talking about fights, yeah sans is the harest, but if we're talking about POWER asriel easily dominates.

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.

Asriel Dreemurr should EASILY be at the top of the list, simply because of all the power he has with those souls. Sure, Sans can dodge almost anything, and Chara and Frisk can completely erase everything, but if you think about it, with all the power that Asriel gets from absorbing every soul in the underground (barring only Frisk's soul, and including all the other human souls, which there are a total of six of), he could easily do either, or even both of those things. Plus, even if he didn't, no matter how many times he gets hit, and who hits him, he doesn't get hurt. So yeah, it peeves me a little that he's in third.

4 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.

Killed Sans. Didn't die when Chara erased the universe. Defeated Asriel Dreemurr (though Asriel is more powerful). And revives every single time he dies through sheer determination.

I think frisk is pretty powerful but not the most powerful due to the average Undertale player not being able to defeat sans and Undyne The Undying.

Well Frisk is basically you, the player, and he could defeat everyone except for Chara, and Chara only appears through Frisk.

5 Undyne Undyne is a main character in Toby Fox's 2015 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 is proven stronger, than Sans, because San's is just learning his patterns, and can only do one damage, Undyne has more health, & is accurate, Sans can only dodge so well because you hit in the same place every time you attack him Undertale, also frisks "Being able to erase the world," Doesn't count, I only admit that Asriel is stronger because he can control time, therefore, stronger.

She literally wanted to murder you from the beginning, and if you couple that with the fact that she is made out of pure determination on the genocide path and has very quick attacks, I think we can all agree that she is extremely powerful.

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).

I cast my vote on this one because
1. The power of her DETERMINATION.
2. I still can't beat UtU (Undyne the Undying) on the Genocide run! I rage quit l0l. Now, I'm not a heartless human, I just wanted to experience all routes!

6 Asgore Dreemurr

Asgore took me days to finish I coudn't finish him because I didn't even have butterscotch pie or a single healing item, so I quit, you fight him in every route except pacifist.

He can spew fire everywhere, and he can rapidly change the color of his trident to almost always hit you with it. This makes him very powerful.

Asgore can be super nice or he can be super hardcore and kill you bro, we should put him in the top 2 at best!

This guy...
Really strong, but gets a LOT easier when you learn his attacks.

7 Toriel

Same as Papyrus, she's actually pretty powerful and would be a really hard boss battle if you could die, but you can't because she's just so caring...

Toriel is so forgiving and they are really kind and sweet they are the best!

If Toriel didn't stop attacking us, she would be a pretty hard boss.

Goat Mom!
Don't care, Want her to be with asgore
For some unknown reason

8 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!"

Mettaton is immortal until you flip their switch, and even when you do, they have that very annoying attack where they throw their soul out (their soul spews out lights which is very hard to dodge).

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.

His/her normal form is Iindestuctible. He should me at least number 5

9 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.

Though they aren't truly canon, Disbelief and Revenge imply that Papyrus' true capabilities are stronger than we could ever imagine. He's just too kind to try to kill Frisk

Papyrus is an awesome dude, and if I use the theory that Gaster was Papyrus' father, then Gaster must have taught him at least the basic attack moves that he used. Although Papyrus was using his easy attacks in the game,...he's just too cinnamon rolly for the world and uses kindness to make sure Frisk/Chara doesn't get hurt.

Yay! Papy may seem like a harmless cool dude, he is Sans' brother and using the theory that Gaster is their dad, Gaster may have at least taught him to use maybe some basic moves.

Almost every time I fought him I skipped the battle but I beat him first try on my second family route.

10 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.

Alpys is just great they always try to impress the player in pacifist route. She is very kind and weird in her own way.

We all know why she is here.

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

She killed flowey
