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.

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 that sans is stronger than he looks he can dodge and knows the resets and other timelines and I think he didn't die in the genocide route cause he has ketchup under his jacket and we didn't see him DIE we only heard him DIE...I think hie was still alive...

He's my favorite character. His puns are so funny and he's stronger than he looks. I've seen some people rage over his boss battle because he was so good.

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

with the power of all the human souls he I just a god he could beat sans easily so I think he should be top of the list

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.

He has every soul in the underground, how is he not the most powerful? He's basically a god.

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 more.

I think Chara is the strongest because she can kill anyone, steal Frisk's soul, and she can erase the world.

Yes, Chara is very strong. But she doesn't truly have a battle so technically from what we know of her she is lower than sans.

She is a stronger character than sans but if sans use determination of frisk chara lose

Why is Chara below Sans?! Sans is literally THE WEAKEST character in the game! He has 1 HP, 1 ATTACK, 1 DEFENSE! Poor Chara should be number one!

4 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)

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

The starter of the genocide, the one that corrupted Chara with evil, the REAL killer

Just like Chara he can erase everything and he has a lot of potential

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, more.

In dying phase undyne too weak but if be undying phase undyne will strong (maybe... just maybe)

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

She has the spirit of a true warrior and is really determined to get to her goal. She has all the qualities of a true warrior.

undyne shoots spears at your face and in pacifist the only way to beat her us to run away

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!

its kill or be killed, but what if I kill myself

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

Omega flowey is OP

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

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

She is my sister

she's strong

Don't laugh

8 Asgore Dreemurr

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

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!

he was hard to get past

He Is Stronger Than Asriel For Some Reason

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!"

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

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

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 more.

Poor bone boy at "bottom". But he just isn't as strong as the others.

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.

Why is The Great PAPYRUS number 10?! HE should be AT LEAST in the top five!

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.

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 more.

We all know why she is here.

kinda strong

She killed flowey

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