I beat him with Ars Arcanum and the Metal Chocobo Keyblade.When he started glowing i just started dodge rolling like crazy, i heard that players are always getting defeated from his Heart Releasing 1-hit kill move, and my sister also had trouble with that move. I guess i was so good with it because i beat all of the other English released games before KH1, because i was really young when it first came out and the closest i was to an RPG back then was watching my older sisters playing The Legend of Dragoon.
