I decided to restart ffx with the cheat codes for the hell of it. So I start the game with all the celestial weapons and what glitches happen? Auron is using Wakka's ball, but the ball has replaced Auron's hand. On his other hand, is Lulu's weapon, but his hand has gone through it.

On Tidus, his weapon is fine, but on his other hand, is Yuna's staff and its located on top of his glove, so it looks like its attached. Funny stuff.
