Drive Extension
Early on in Kingdom Hearts 2, Sora receives new clothing, replacing his rather silly looking attire from the original game. At the same time, he earns the ability to use Drives which, among many other things, further alter his appearance while activated. Interestingly enough, there is a simply way to extend the length of a Drive's visual transformation, so as to reflect in cut-scenes as well: During any of the game's numerous objective based fights, simply complete the event with a Drive activated and Sora will retain his modified appearance for the story event that follows.
