Batman is cool because he doesn't need toxic waste or gamma rays to be a great superhero. He's equipped with some of the most awesome weapons, such as Batarangs, and, of course, the Batmobile.

Batman is the best because he doesn't even need super powers to fight crime and be awesome! Even in his alternate identity, he is still an awesome rich guy!

all the gadgets & the sweet ride

No other hero could bring him down, he's always ten steps (at least) ahead of everyone else

Spider-Man has been the coolest Marvel comic for a long time. Countless comic books have tried to beat Spider-Man, but it seems close to impossible

I think Spider-Man is really cool because he has web in his suit and it can shoot out! And his costume is super cool!!!!!

The suit is so awesome. I wish I could wear one forget superpowers, super iron man suit beats the all. Tony Stark is a geniusM+38

Cool, funny, easygoing attitude. He's also a genius. He's really a personal favorite of mine because once this guy who thought I was a genius said that I should build an Iron Man suit to go to school. That would be awesome - I've already started to work on it :) Easily the best Avenger and probably the best superhero!M+29
