I can't think of anyone I hate. I just love KH so much that I love all the characters. Even the most annoying ones. But I have to agree that some characters still need some development. To tell you guys the truth, I don't see any use for hating a game character. It's not like they really exist or anything(not that I'm supporting hating people in real life), but it's just a game. Don't need to take it so seriously. Besides, it's a waste of your brain cells.
