which makes Thor able to carry more heavy stuff to throw.
Thor's hammer is enchanted, that's why Hulk can't pick it up. So it doesn't necessarily mean Thor can lift more weight then hulk, just means he can pick up his hammer.
Batman hands down. He has like, every gadget ever. Spiderman may be some college nerd, but he's dumb compared to Batman. Also, Batmobile, and Batrangs, and Batplane, and Batcycle, and Batgun--wait, no guns. But Spiderman has 0 weapons. Batman has several weapons. Also, Spiderman is very hard to miss, with his red suit, while Batman is pretty stealthy.
Now..it depends. If they get no preparation time and it is a completely random battle, Spiderman wins EASILY. If they get preparation time, then Batman wins.
I've always liked the idea that, if you're rich enough, you can become a superhero. Even though it's a strongly fictional idea, Batman made it a reality for himself. Spiderman got bitten by a spider and acquired his powers by chance and luck. There's nothing cool about that.
2) He was never a villain. He was always an anti-hero. He started out as a mercenary (merc with a mouth) and then all the fun stuff happened that would be too long to get into and I have to go anyways
