Top 10 Hardest Nintendo Bosses

KirbySonicDonkeyKong

The Top Ten

1 Inner Agent 3 - Splatoon 2 Octo Expansion

Who the heck even made this? Inner agent 3 brings out my SALTY-NESS

The real reward was bragging rights, not a toothpick.

I have to go to therapy from this

Took over 10 hours to finally win

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

I can never get past this. - smobowser

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!

Great call for a difficulty spike!

3 Bouldergeist - Super Mario Galaxy

He is easy as pie! just throw some bomb boos at him, and BOOM! boss fight is over!

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

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

He,s in possible to destroy! ¡!

This boss attack moves are like ultra sans

All the people saying tabuu is hardest obviously didn't hear of sm4sh - VideoGamefan5

No. Just use a power-modded Captain Falcon.

Not Nintendo, just sega

9 Tabuu - Super Smash Bros Brawl

Hard for sure, but not insane. I beat him on all difficulties except intense. he's like Toads Turnpike REGULAR NOT MIRROR ddifficulty.

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

Beyond incredibly hard on Intense mode! Should be number 1! - Blubbydubber1

Almost impossible on Intense Mode

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!!

Should be number 1

How the heck this guy number 13

Instant kills every hit for 90 seconds.

12
13 Weldar - Banjo-Tooie
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!

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

47 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.
