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 ...read more.

Honestly I LOVE Sans he's super funny and can be more powerful and the only reason he "Died" in the game was because he was SUPER tired How would you feel if you had to keep fighting over and over and over again I would be super tired and he also can see all the timelines which I know some others can do BUT Sans has a good soul too as he tries to keep a promise from goat mom for you AND (I don't know if this actually happens as its just in animated video) he picks you up like when you die a final time maybe? I'm not sure but he tries to be kind to you. Besides he is also mentally strong, people don't realize that he has to watch his friends Die over and over and over again and be the only one to remember it would be pretty hard and honestly I wouldn't be surprised if he actually was depressed an that big smile was fake... please take this into mind before saying someone else should be at the top... because sans has been through much more...

He can defeat you the player with the ability to reset time. He has the ability to dodge, and he has that karma thing that will deplete your health until it is at 1 and then just one hit and you are finished. Plus, the fact that he has not given up even through all the genocide timelines shows that he has a strong soul. Also, tibia honest the puns, they tickle my funny bone.

I think sans because he's really cool

1.he could teleport
2 he could control how frisk/Chara moves
3 if you give him mercy he could kill you
I just wonder why he doesn't kill frisk/chara immediately without giving mercy

Okay, let's see...
-Can teleport
-Telekinesis
-Gaster Blasters
-Only boss that does poison damage.
He should be a cop because this is one justice-loving skeleton.

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

Aerial should be on the top of this list. He's literally god and can use all the souls at his will. The only reason you don't die is because in the omega flowey fight he says he wants to watch you die over and over again. Another thing, he's the only one to break the barrier. No other monster could do that. Finally, he never takes damage and all his attacks do more than one, he's clearly stronger than sans.

Well, basically Asriel is supposed to be second because he can control the timeline, and if he wanted he could've reset everything if he wanted to.

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.

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.

3 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 ...read 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

Chara is Cute for me then I like her power as a demon Me and Chara Are The same My Birthmonth is September,My Birthday is Sep.19 and hers is 9 I’m scared of spiders Same as her TwT and last My Favorite Food CHOCOLATE! :D

Chara
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.

4 Frisk

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

Frisk powers

1. Determination (Revive after death)

2. Is A Human (As said in the game, it would take every monster soul in the underground to equal the power of one human)

3. Save files

4. Reset (Frisk's most powerful ability in the game)

5. Exists outside of the game (You are 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.
Thanks!

He/She was able to change the world and defend himself/herself against all monsters and continuously avoid their attacks.

5 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, ...read more.

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!

Undyne is the strongest monster, excluding Flowey with SOULS. Her insane spear attack, her great speed, her insane defense, but, most importantly, DETERMINATION.

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).

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.

6 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!

If he has the 6 souls, he beats everyone. The only reason he was beaten was because the souls rebelled.

He's just a flower but he's still hella strong and evil.

Total weirdo, but true strength...

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

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.

She's can actually kill you.

She is my sister

8 Asgore Dreemurr

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.

A kid and a flower beat him

He's a king.

9 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

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

I had a lot of fun battling MTT

10 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 ...read 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.

Papyrus is actually really strong like sans.He just uses weak attacks since he is to nice to hurt you.He's a big cinnamon roll.

The Contenders
11 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 ...read more.

she is the bottom because she is a boss
(just joking you know why she would be the last)
I've bee wondering if she have magic or not...? or she rather just don't show it
(froggit is even stronger)

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

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

We all know why she is here.
