Top 10 Strongest Undertale Characters
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 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 six souls. Asriel Dreemurr's fight basically blocks inevitable deaths, meaning you cannot die. Sans' fight doesn't do that. There are no checkpoints or 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, or the Protagonist, whichever one you prefer, Sans is the boss-fight that kills you (possibly) more than bosses such as Omega or Asriel in-game. Sure, I do agree other bosses have their amazing amounts of strength, such as Flowey almost killing you in one hit in the beginning before Toriel saves you or Chara at the end of a Genocide run if you decline their offer of the erasing of the world, but in technical terms, my vote goes to Sans.
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... read more Chara can erase the world. 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's soul and she wants to get rid of the world (Earth and the underworld). So all in all, Chara is the strongest character in Undertale.
Frisk can defeat all monsters at LV 1 and easily defeat them in the genocide route. At LV 20, Frisk can easily kill Flowey. In fact, Flowey knows he's no match and is so afraid of you that he even knows his Omega/Photoshop form is no use.
Chara… they overpower Frisk's choice when they say "Do not (erase everything)." Frisk can't even bring everything back if they want and have to strike a deal with Chara to do so. Even with max LV, Chara obliterates Frisk with infinite damage and surpasses any defense Frisk has. It's a huge mistake bringing out this kid.
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... read more
Overall, Asriel Dreemurr is the most powerful character in all of Undertale.
Why you ask? Well, let's start off with the fact that Flowey had consumed six 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 in all, Asriel is the most powerful character in Undertale due to having six souls and all the monster souls.
Frisk has a human soul, and she can't lose it because of her determination. She can reset the universe and has killed everyone in the genocide route.
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 guidance, and Asriel does not seem to have full power over the timeline. 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. All of the characters above Frisk have their own reasons which are completely valid. I am just showing my opinion.
Thanks!
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 Undyne is proven stronger than Sans because Sans is just learning his patterns and can only do one damage. Undyne has more health and is accurate. Sans can only dodge so well because you hit in the same place every time you attack him in Undertale.
Also, Frisk's being able to erase the world doesn't count. I only admit that Asriel is stronger because he can control time. Therefore, he is stronger.
Undyne the Undying is literally the hardest and the most unpredictable enemy (second only to Sans). Still, she is very hard in general. Also, she is the only monster to overcome determination (Alphys did say monster souls can't contain determination, but I guess Undyne's was too strong, even stronger than death).
We never saw his true power and he was most likely holding back while fighting Frisk. But, he did destroy the mercy button, which is very impressive. He also fought in the war between humans and monsters (probably).
Asgore took me days to finish. I couldn'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.
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 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.
Okay, I think this is fair because she doesn't actually kill you. She backs off on like her third attack.
If Toriel didn't stop attacking us, she would be a pretty hard boss.
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 three 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.
Mettaton is immortal until you flip their switch. Even when you do, they have that very annoying attack where they throw their soul out (their soul spews out lights which are very hard to dodge).
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 He has such precise control of his attacks to weaken you to 1 hp. Also, in the true pacifist route, when Flowey traps everyone with vines, he uses two vines for everyone but Papyrus. Flowey used more than two vines for the others.
Papyrus may be stronger than you think. He has such precise control of his magic to make you go to 1 hp without killing you. Also, in the true pacifist route, Flowey uses two vines to tie everyone except for Papyrus. Flowey used more vines for 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.
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 Alphys is just great. She always tries to impress the player in the pacifist route. She is very kind and weird in her own way.
She only attacks you once, and it's while she's a lost soul. It ends up being a little bit of Mettaton's attacks.
She has created Mettaton. Give her time for more powerful monsters. P.S. she made Undyne so powerful.
