You know what I think they did? They took pieces of their personality from certain games. Like, they took how jealous Riku was in KH and made that his main personality in their doujinshi. Same with Sora, he cries ONE time in KH2 *and for good reason* and they blow it up so he's this crybaby woobie in their doujins. Kairi isn't TOO horrible in their comics, but still. It's....frustrating to read. Anything with a good story are horribly drawn or ok... anything awesomely drawn are ooc. Of course there are exceptions, but not always. =_=
