Top 10 Hardest Nintendo Bosses
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.
It took me about a week, everything about this battle is hard, the autobombs, the bubbler and what killed me the most the splashdown

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

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.
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
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
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.

Not Nintendo, just sega
Ah yes, my favorite Nintendo boss: [REDACTED]
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
Hard for sure, but not insane. I beat him on all difficulties except intense. he's like Toads Turnpike REGULAR NOT MIRROR ddifficulty.
You mess up, and you have to start again FROM THE FIRST TRIAL.
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]
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

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

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.
Awesome but really annoying and ugly
This boss is hard but definitely not the hardest boss in the kirby series.
