I dunno. I just like the mysterious characters better. No matter if it's Anime, FF, anything.
Like, I like guys like Squall, Vincent, Auron, Sasuke for example just because they fit what I like in characters.
Cloud I find is too much of a blonde bimbo that is more then anything used as fangirl bait. I didn't mind him at first, hell I actually thought he was a pretty awesome character. But fangirls killed it.
