Have you beaten him on KH2? His Sin Harvest attack was even more of a pain in the ass because he flew up into the air and if you were on the other side of the arena the only way you could possibly get to him in time was to glide.Catkid906 said:Sephiroth from Kingdom Hearts 1.
He had a shield around him so you can't make a hit on him. It turns off for 2 seconds at some point, but then he decides it would be more fun to use more powerful attacks. This is a real pain on the hardest difficulty.
