Hardest Nintendo Bosses


The Top Ten

1 Inner Agent 3 - Splatoon 2 Octo Expansion

I have to go to therapy from this

Took over 10 hours to finally win

To you casual, uneducated, normies who can't beat a boss with a challenge more minor than your worth, git good.

I was almost shaking during this. My armor was broken at least three times a phase and the autobombs almost made it impossible. If I was the director of Octo Expansion, I would fire whoever came up with this level.

2 Cackletta (Last Battle) - Mario and Luigi Superstar Saga Cackletta (Last Battle) - Mario and Luigi Superstar Saga

One of the only times a Mario boss has been hard, was about to pick Bouldergeist, but realized one of the only reasons I was terrible against him was because I sucked at 3D Mario games, and I still kind of do.

1 hp just 1... I lost a few times!

She is a VERY, VERY HARD boss. My opinion of the hardest boss in Nintendo's history, maybe the hardest boss in VIDEO GAME history!

Great call for a difficulty spike!

3 Bouldergeist - Super Mario Galaxy Bouldergeist - Super Mario Galaxy

Is this hard? People are crazy. The attacks are slow, a million bomb Boos spawn each time and he's so big, you can't avoid hitting him.

Definitely the most difficult boss of all time, It is much harder than. Really impossible

I spent two hours trying to beat this guy on the daredevil run

4 Ganon - The Legend of Zelda Ocarina of Time

It took me FOREVER to figure out how to beat him. I hated having to go through the castle every time.

It is not that difficult - Retroman64

5 The Hag 1 - Banjo-Tooie

Very difficult to pass on replay mode with 5 health! Dodging the back lasers and positioning to get the clockwork kazooie eggs in on time is difficult but worth it.

6 Metal Madness/Overload - Sonic Heroes

This boss is hard but it's not a Nintendo boss it's a Sega boss

7 Egg Emperor - Sonic Heroes

Not Nintendo, just sega

8 Master Core - Super Smash Bros For Nintendo 3DS and Nintendo Wii U

He,s in possible to destroy! ¡!

This boss attack moves are like ultra sans

9 Bonetail - Paper Mario: The Thousand Year Door

You mess up, and you have to start again FROM THE FIRST TRIAL.

10 Tabuu - Super Smash Bros Brawl

He wasn't even hard in my opinion.

14 The Shadow Queen - Paper Mario: The Thousand Year Door
15 Gyorg - The Legend of Zelda: Majoa's Mask

If your jump isn't perfect you DIE

Why he's not on this list? He is hard as hell! You need to get in the water to hit him and if you don't escape from the water quickly, you lose like three hearts!

33 Disciple Lorithia - Xenoblade Chronicles

Undyne is nothing compared to the Sans in genocide. I haven't played the game, but trust me. - Synchronocity

43 Takumi - Fire Emblem: Fates
44 The Creators - F-Zero GX
45 Diamond Dog - Earthbound

Diamond Dog is the final Sanctuary boss of Earthbound (or Mother 2 as it is known in Japan)

46 Zanza - Xenoblade Chronicles

This guy took me 30 tries to beat.
First of all, his amount of HP is HUGE. You can barely see the health meter drop every time you hit him.
Secondly, he will constantly give you annoying debuffs.
And lastly, every once in a while, he will unleash an unavoidable attack killing everyone on your team except for your tank, or perhaps maybe someone with a defense buff.
