I don't like most DC characters. (Superman I found was jsut a cheap character.) But what I liked most about Batman was.... He's just this guy. He's not a mutant, and he doesn't have any alien artifact, or anything of the sort. He's just a guy in a cool cape that has cool gadgets. Sure, he's a billionaire and everything, but he's so normal! You point a gun at him, he gets scared. He can easily die. And I like that he's a good guy in a bad guy costume. He's so evil looking, but he's so nice, but so hardened by his past. Man, HE'S SO COOL!
But, I jsut like the depth of Marvel comics, and how even the most powerful of characters have inner demons and everything (a fine example of that would be Spiderman, as we all know) And even users of the power cosmic (my favorite power EVER!) has troubles coping with what he does. (Not Galactus, Silver Surfer, my fav ultima-hero [hero that has near ultimate power])
Well, I'm just a normal fanboy that has something some other fanboys don't.
