The Top Ten
1 Asriel Dreemurr Asriel Dreemurr is a character from the 2015 game Undertale. He was created by Toby Fox.

Asriel is the child of King Asgore Dreemurr and Queen Toriel, but he seemingly passed away prior to the game's events. His backstory is only focused on in the True Pacifist Route, which means the player does not kill a single character. As a young child, he was a close friend of Chara, a human child who... read more

This was a toss up between him and Chara because they really cannot beat each other. Despite Char being killable, Chara can reset. Asriel can not be killed. He can only be beaten by someone PURR OF HEART. And that right there is why Asriel wins. Chara is a psychopath. She is pure evil, thus she cannot harm Asriel. On the other hand, Asriel could simply kill Chara over and over again. Him having the ability to kill Chara gives him the edge and title as most powerful character. Plus he is a god so

He literally is a being made up of EVERY soul in the underground. Sure, his boss fight is easy, but he has the power of: Seven Human souls (If I have my facts straight, he had absorbed Chara's SOUL and I think he still has it, and he did absorb the six human souls that King Asgore had), The head of the royal guard who refused to die if you go on the Genocide run, The king AND queen of the Underground, A royal guard in training, two ghosts, AND the guy that took me 50 tries to beat him (Sans)! He is the most powerful monster in the underground. And that's a fact.

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 player's name, which is Frisk. In the genocidal route (achieved by killing as many monsters as you can without sparing), they appear by the end to destroy the world, which happens regardless of the player's choice or intervention. Due to this, most people see them as a villain.

Chara is probably the most unbeatable character in the game. Like Frisk, she can reset. She can basically kill every monster with just one slash (except for Asriel). No matter how many times sans defeats her, she only needs to hit him once.

Please don't yell at me, I don't think that Chara is evil, I think that she/he was just driven mad by the player, because they were *cough cough* just KILLING EVERYONE THEY HAD EVER KNOWN?!?!?! *cough cough* and don't give me the “but what about the tapes? Where she/he laughs at Asgore getting sick? ” It is seen many times that laughing in Undertale is more of a coping mechanism for grief than anything else. Take Sans. He is always joking, laughing, and making puns, right? Well, he is always haunted by the thought that the player might kill everyone he has ever know. Also, snowdrake’s father in the MTT cafe thingy laughs and then says, I quote, “That’s not funny.” So, I rest my case.

3 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 boss fight, bad puns, and the phrases "geeetttt dunked on!!!" and "you're gonna have a bad time." He is also named after the font "comic sans." Known for also being Ness from the Mother series. (known as Earthbound in Western territories.)

Sans has to be the most overrated character in undertale. Despite this, do not underestimate him. Though he only has 1 hp, it is nearly impossible to hit him due to his teleportation. He is the hardest boss in the entire game. I could make a long montage of him killing me over and over and over again. Oh, the horror.

4 Frisk

She is the protagonist. Of course she will be on here. She “defeated” Asriel and somehow beat a ginormous flower monster. If that was real, she would lose. She has beaten every monster in the game. Though Asriel was only using a fraction of his power.

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

Flowey is 100% just like chara

6 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, ...read more.
7 Asgore Asgore Dreemurr is a boss monster and the king of the monsters in the 2015 RPG Undertale made by Toby Fox. Asgore is the portrayed main antagonist who plans to acquire seven human souls and use their power to break the barrier that seals the monsters underground . Aspects of his character are hinted ...read more.
8 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 . Gaster feels like a character that is left behind since nobody really visits him . But you can encounter him in the waterfall exhibit while following Sans to Grillby's . W. D Gaster is also believed to be the father of Sans and Papyrus .

He is kind of adorable. I forgot my own name.

GASTER IS IN CONTROL OF ALL TIME AND SPACE

The one who made this list doesn’t know that something which is labeled as „Non-Existend“ has no Hit-box and Health-bar
Wich means you can't kill Gaster.
He also is in control of the void.
And he can use the power of every soul except determination wich also means that he LITERALLY is able to control time and space.
Also the fact that he is Non-Existend means that he has no soul wich means he can’t run out of stamina/energy
If Asriel and Gaster would fight each other Gaster would win because Asriel may be the God of Hyperdeath but Gaster has a power wich is far beyond anything even a god could understand ,wich means that Gaster vs Asriel is like Rocketlauncher vs Housefly.
Basically Gaster possesses a power wich is more than enough to create a multiverse so Gaster has the power of Omnipotence wich means that he can kill a entity with just a thought wich makes him the most powerful and dangerous character in the whole game.

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!"
10 Toriel Toriel is a goat like monster who is the secondary major character in Toby Fox's 2016 RPG, Undertale. She saves the protagonist from Flowey and guides them through the Ruins, of which she is the self-proclaimed caretaker. She is the ex-wife of Asgore, the mother of Asriel Dreemurr, the adoptive mother... read more
