[Super Buu]

Koola, Silver and Bujin aren't doing a 'split personalities' thing as such, by the way. They've just got demonic souls trapped in their bodies via tattoos. I think it's just a storyline. I actually quite like it, because the personalities are pretty unique, not, as I said before, just generic voices of Good V. Evil.

Buu's personality shifts slightly as he turns into his Spiritken form, but I view that as more of a 'focusing' rather that a new personality. He's the same guy, but just more focused, more strategic, and less liable to mess around during a fight. Sort of the opposite of the whole 'SSJ Rage' thing.
