does spiderman have a kryptonite? is it mary jane? if so, what is batman's "kryptonite"? having to defend my position on this and need some insight/back-up. new poster, thanks. -J
In order...
1. Spiderman - no kryptonite. But he isn't the strongest character at Marvel (unless you count box office gross). So, you can say that any character that is stronger, faster or smarter than him "is his kryptonite", which would be Thor, Captain America, Iron Man, Hulk, and on and on...
2. Sure, Mary Jane too. (Not really.)
3. Batman isn't bullet proof, needs to get rest, has to shave in the morning, and so on. So, because he doesn't have "super-powers" - he doesn't need something like kryptonite to kill him. A gun would do just as well.
Good luck defending you position.
