Deffinetely Riku. He is such a bad@$$, Sora is way to childish. His clothes are like...red and blue and he wears like so much. I dont get how he can even move..and he lives on a hot island, i thought he would die of heatstroke.
Riku is dressed more suitably (sp?) In a tank!! And his hair is so cool lol, silver!!! And when he was possessed, he looked so cool!!
So Riku by a really long shot.
