There is some spoilers here.
The Top Ten
1 Ballos (Cave Story) Ballos is a character in the video game "Cave Story." He is a powerful magician who was sealed away due to his misuse of dark magic. Ballos is both tragic and menacing, serving as a formidable final boss in the game. He embodies themes of power, corruption, and the consequences of unchecked ambition, contributing to the game's intricate narrative.

You have to get past the whole UNDERWORLD to get to him.
Oh, and if you die on him, you go back to the start of the underworld!

2 Tabuu (Super Smash Bros Brawl)

Why is Ganon from ocarina on here? Yes. he's challenging but he's hardly a candidate for hardest boss battles. This guy is the hardest because he can one shot you and dodging the off waves is hell.

3 Demise (Skyward Sword)
4 Majora's Mask, Incarnation, and Wraith (Majora's Mask)

No joking, I actually beat this boss on my first try.
Well, maybe I'm the only one who thought it was easy...

5 Monster X (Cave Story)
6 Ganon (Ocarina of Time
7 Galactus (Marvel vs Capcom 3)
8 Sans (Undertale) 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.)
