I definitely play the best as Aqua, which honestly surprised me at first because she is a magic-based character and I have never been very magic-heavy in any other KH game. I thought I would be the most comfortable playing as Terra, but no, definitely Aqua. I love her aerial movement, her 360 degree block, and I also think of all the characters, she's the most powerful overall. Her magic can literally one-hit KO most Unversed at level 30-ish.
