Top 10 Undertale Bosses


The Top TenXW

1MettatonMettaton 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!"

All right! I think we were all expecting Sans but I definitely think Mettaton is the best. He also has by far the best theme song and of course the best legs.

Wow! It's cool to see him at number one! He's probably my favorite. - Garythesnail

Hell yeah look at those ratings - SpyroZap99

2SansSans 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.

Such a troll and the theme is so awesome I could listen to it for 10 weeks straight. I'm a lot like him too. I'm lazy and I can't stop making bad puns. I've listened to multiple versions of the song and all are rated over 1 million!

Seems like a cool boss, but I haven't got anywhere near the heart that a Genocide run requires. - Garythesnail

No explanation needed. Just prepare to get dunked on.

3Asgore Dreemurr

The epic opening, breaking mercy, forced to fight the kindest monster in the underground, his final words, the bitter end. no other boss represents Undertale better than Asgore

This is a boss that is not only difficult, it's a pretty emotional one. He's reluctant to fight, he can't even look at you in the eye, the music fills the atmosphere, his attacks weaken as your HP lowers, etc. enough said.

4Asriel Dreemurr

He's not the hardest boss but it is an amazing showdown

He's not very hard since you really can't lose, but he's the boss that'll probably pull on your heartstrings the most, only behind Asgore.

Asriels my personal favourite character and has a variety of attacks

5PapyrusProbably the second most popular character from the already insanely popular 2015 indie RPG known as Undertale, Papyrus the skeleton is Sans' taller and skinnier younger brother (much like how Luigi is to Mario in the Super Mario Bros series, except that Papyrus is physically stronger than Sans) who more.

I love this boss but there is one downside, to spare him you just have to die to him 3 times (I think)

6Photoshop Flowey

First thing that comes to mind: WHAT IN THE NAME OF ALL THAT IS LIFE IS THAT?! This guy has no strategy, no mercy, just pure bullet hell. The only reason I don't really consider him top 3 worthy is because he really isn't that hard (unless you're doing a no-hit run, then good luck).

7Undyne the Undying

Her song is one of the best I've heard in this game, her fight is innovative, it's fairly challenging, enough said.


She's definitely one of the easiest bosses, but also one of those bosses that can really pull on your heartstrings.
