I made a new poll for the hardest boss of KH Series because I realized I forgot some bosses that some people very kindly pointed out. I will make the max amount of things u can vote 4. (Note: 10 is the max) Plz vote. If someone wants to make a point of another boss please post it.

That fight with Riku in KH1 when its just you and him. OMG! I was on that for 3 days I could not beat him to save me.

I think you should add Kurt Zisa, still havent beat him and i beat sephiroth in 1 so i guess that was easier

kh rcom marluxia preety hard

I demand a Xaldin option! He's the only boss that has made me so mad that I broke a controller! Three days of constantly trying and dying... three painful days..........

 

Okay I can't pick Xaldin but I can pick some pretty good ones on here.... Vanitas lingering sentiment for me. I was stuck on him for a bit til I got in the groove and won. Then Sephiroth in KH1... I have only beaten him once... don't care to try again.

His name is NOT Terranort. If you don't believe me read the Credits.

So far my hardest battle was Sephiorth from Kingdom Hearts II on Proud Mode.

 

Its a fan term Sora, seriously...

KHII Sephiroth the only boss I could never beat

Sephiroth was always annoying I hated fighting him

WHY DON'T YOU GUYS TALK ABOUT THE DUSTFLIER?! THE ONLY BOSS I HAVE NEVER BEAT!!!!

Sephy KH1 and Terra' Remnant.

 

I was looking for No Heart and MF, but they weren't there...

Haven't played any of the final mixes, and both the Sephiroths were kinda easy. Lingering spirit Vanitas is hard as BAWLS!!! Still haven't beaten him. Honestly I gave up after a little while lol rage quit.

The Lingering Sentiment is by no doubt the hardest KH boss I've ever faced. I once fought against him for 5 hours straight and got my ass handed to me over and over again.
