Top 10 Hardest Nintendo Bosses
Easily the hardest boss fight in a 3D Nintendo game and the hardest secret Nintendo boss. Bouldergeist has attacks that are easy to get used to once you have tried to beat him several times. Meanwhile, Inner Agent 3 can be quite unpredictable at times. Their aggressiveness and special usage test the skills of your movement and your ability to utilize surroundings to your advantage.
If you are very skilled, then you should have no problem beating them in fewer than 30 tries like me. Though, I can't imagine what they would be like on a harder difficulty.
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.
It took me forever to figure out how to beat him. I hated having to go through the castle every time.
Bonetail is not too difficult if you have the right equipment. The difficulty is apparent because you have to battle 99 sets of enemies in a row without dying. Most likely, you'll drain your resources if the enemies beat you up really well. Other than that, the actual boss is about as difficult as Bowser from Paper Mario 64.
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 you'd think. Really impossible.
Hardest non-final, non-secret Nintendo boss.
One of the only times a Mario boss has been hard was when I was about to pick Bouldergeist but realized one of the only reasons I was terrible against him was that I was not good at 3D Mario games, and I still kind of am.
Spend a turn healing, dodge, and then you should be good. Doing this with no heals and 1 hp, however, is a valid reason to rank this as hard as it is.
Great call for a difficulty spike!
Beyond incredibly hard on Intense mode! Should be number one!
Mike Tyson should be number one. Most of these bosses are vastly easier compared to him.
I was only able to beat him by using the Nintendo Switch Online rewind button.
Instant kills with every hit for 90 seconds.
Tip: When Shadow Queen uses her hands, charge up Yoshi Kid with Mario's turn, and use the Stampede to wipe out the hands for two turns.
This guy is number 17? Try the Battle Tree in Ultra Sun and Moon on Super Battle, and beat him!
Why isn't he on this list? He is extremely difficult! 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!
Wally Warbles is extremely super hard on Expert Mode!
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.
