Top 10 Hardest Nintendo Bosses

The Top Ten
1 Inner Agent 3 - Splatoon 2 Octo Expansion

I like how octolings have the aim of a blind man, never use their sub weapons, and can't use special weapons usually. And then there's this.

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.

Hard. Takes two hits from 3 to break your armor, then u need to shoot them 10 times. Plus autobombs and panic splashdown when your armor's broken in last phase

There is no other words to describe this other than just mean. I had to take several breaks during the fight.

2 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.

Great call for a difficulty spike!

I can never get past this.

Wow this was very hard

3 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

Hardest non-final non-secret Nintendo boss.

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

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.


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

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

All the people saying tabuu is hardest obviously didn't hear of sm4sh

This boss attack moves are like ultra sans

He,s in possible to destroy! ¡!

No. Just use a power-modded Captain Falcon.


8 Tabuu - Super Smash Bros Brawl

Even on the easiest difficulty I had a hard time with this guy

Beyond incredibly hard on Intense mode! Should be number 1!

Almost impossible on Intense Mode

He wasn't even hard in my opinion.
You have like 7 characters to kill him.


Not Nintendo, just sega

Ah yes, my favorite Nintendo boss: [REDACTED]

10 Bonetail - Paper Mario: The Thousand Year Door

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

The Contenders
11 Mike Tyson - Mike Tyson's Punch-Out!!

I was only able to beat him by using the nintendo switch online rewind butten.

Instant kills every hit for 90 seconds.

How the heck this guy number 13

Should be number 1


Ah yes, my favorite Nintendo boss: [DATA EXPUNGED]

13 Weldar - Banjo-Tooie
14 Gyorg - The Legend of Zelda: Majoa's Mask

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!

If your jump isn't perfect you DIE

Water boss enough said

15 The Shadow Queen - Paper Mario: The Thousand Year Door
16 Red - Pokemon HeartGold and SoulSilver Red is a Pokémon Trainer from Pallet Town, Kanto. He is the first character to be playable in the Pokémon series and his initial appearance is set in the Generation I main games. He has since then made various appearances in Pokémon media, including the Generation III remakes of Red, Green, Blue, more.

This guy as 17?
Try battle tree in Ultra Sun and on super battle,And beat him!

17 Marx Soul - Kirby Super Star Ultra
18 Grodus - Paper Mario: The Thousand Year Door
19 Dark Link - Zelda II: The Adventure of Link

The only reliable way to beat this fight makes you feel like a cheater, but if you try to fight him any other way it's basically just luck-based.

Let’s be real who really played Zelda two without quit or taking eyedrops from that one stupid temple

20 Bald Bull Title Defense - Punch-out Wii
21 Shadoo - Super Paper Mario
22 Fiery Gobblegut - Super Mario Galaxy 2

Awesome but really annoying and ugly

23 Mimi; Second Fight - Super Paper Mario
24 Paint Roller - Kirby Canvas Curse

This boss is hard but definitely not the hardest boss in the kirby series.

25 Mother Brain - Super Metroid
