Not to mention their weaknesses. What's Superman's weakness? Kryptonite. (Lame.) Green Lantern? The color yellow. (WTF?) I think Batman has the only real weakness and that is...bullets, knife, falling from a high place (though the movie tend to do away with those with his body suit, but you get the gist of what I'm saying.) Batman might be DC's poster boy, but he's anti-DC in the fact that he's a normal guy in a costume who has a tragic beginning, normal weakness, and an internal struggle. I don't know much about DC, but it seems to me that Batman stands out in those regards. And look at his costume: gray and black (with an occassional splash of yellow depending on the artists.) Most of the other ones have bright colors. Anyway...I digress. Weaknesses are lame and kind of half-assed attempts to throw in conflict.
And on the Marvel side? Same as Batman's weaknesses! Spidey or Captain America sees you trying to pull out a shiny green rock to save yourself a thrashing and they're going to laugh at you and punch you in the face. Now...a bullet to the gut (depending on their body armor, ability to deflect or dodge it) is another story. Spider-Man isn't likely to get shot, but in the event he does, he's gonna bleed.
