Hardest Boss?

I did find him easy...but thats mostly becuase I healed everytime my life was low...I let him knock me around a few times after words just to use micky but other then that he was easy...

 

Hardest boss fight would be Demyx he's hard using his water wave power and also his water guitar people on the second in the clock. -_-.......

 

I agree with that, It stressed me out until I finished him off

 

SEPHIROTH, Like holy crap I lost my mind when I beat him.

 

I still didn't beat him yet -_-

 

I didn't have much trouble with most bosses because I tend to grind even early on. Demyx, like stated above, was a pain. Simply the way he kills you by you not being able to defeat his water notes got annoying.

 

I would say Xaldin and the Grim Reaper from Port Royal.
Although Xaldin was reaaally hard the first time I played the game, I enjoyed fighting him because it's a challenge, and the Grim Reaper was just plain annoying. Seriously, every time I got the coins and wanted to put them back he took them again. I was so glad when I finished him.

 

Xaldin.

Being able to play as Mickey almost made me want to die, but Xaldin was pretty hard, although I only died once.

 

The first time I played it through Xigbar hands down was most difficult, playing it again I'd say Xaldin I think.

 

Xaldin is hard but once you get used to him his movements are pretty predictable...

 

Hardest boss is Sephiroth, no doubt about that. I had some trouble with Xigbar, and Xaldin. Demyx was pretty annoying with his water clones, which were the only reason I lost against him many times.

 

Demyx... RAGE.
Not only his water clones, but his constant spamming of overpowered long-ranged water pillars made the fight almost as hard as the final boss -_- however Sephiroth is the hardest boss, no doubt about that.

 

Xaldin, it pissed me off having to fight with Mickey due to me constantly dying.

 

Terra in KH2 Final Mix
that was hard as heck
But i beat him
-MY ADVICE IF YOUR GONNA GO AGAINST HIM-
he has an MP Drain thing so dont pack much ethier's and go strong on the Potions in your invo
And for this i would also try to use as many negative combo powers+items you have

 

Never played final mix but I had trouble with Xaldin like the others though. once I have all of the bosses patterns memorized i usually die on purpose to play as Mickey I think whether you can is determined by your drive gauge.

 

In Kingdom Hearts one I had the hardest time with Arsala. In Kingdom Hearts 2 I had the hardest time with Demyx and Xaldin.

 

Even though I replayed and beat Kingdom Hearts 2 atleast 10 times, I could never perfect Demyx and Xaldin, Those were the two most annoying.

 

Shadow Stalker. I was way underlevled at the time...

 

Oh man i was never able to beat to defeat the big robotic looking dragon thing at the end. right after you "beat" xemnas. ugh that thing was very difficult and i kept dying

 

Xaldin. Before today I only managed to beat him after being saved 4 times in a row by mickey :s I battled him on standard today at level 38 and only got saved once.... I'm getting there... slowly.
I also used to find Demyx's battle infuriating but I've discovered comet makes destroying the forms so much easier.
