oh, he's got character. Just too much of it. If you know what I mean.

Now, if your talking about the game characters liking him, then I stick with my previous reasoning: he's good-looking. Said and done.

If your talking about real people (aka players) well that's a whole new story. Who knows. Many things. For one, he's a very weak character. This makes him seem more human, and would make him a more appealing character to some. Unique weapon always helps. Also, he's got one screwed up past, one that simply gets people totally absorbed in it, as they try to unravel it. This is just something that many people find interesting, so he comes out as a favorite. (why do people like extremely complex chars? I have no idea. o_O) Not to mention he's the major love interest of other extremely popular chars. So that's a bonus. and again, maybe it's just for the character design. It's all on personal preference.

Or it could just be because of that hair........
