I think that Oogie Boogie is pretty annoying because he's always making those weird noises, and in the first battle in the first game, it's so confusing!
Why would people hate Kairi? I like her because she's a nice person and she cares about people.
Well, we've played as Sora for both games but Roxas is pretty cool and he's in the Organization, so I can't really choose.
I like blindfolded Riku because he looks really cool and I love how he fights Roxas to see Sora.
