Take strength, agility, intelligence, and additional powers into consideration when answering this. I've noticed on the battle forums that good Spider-Man fights are hard to come by.
He's in this weird place where he whoops on most street-level heroes not named Batman, and yet he seems to get owned by anybody else with serious superpowers.
I want to say the closest hero I can think of in terms of power level is Captain America. But when you think about it, Cap doesn't technically have superpowers. I guess most people agree that Spidey would own Deadpool, but then again it seems most Marvel characters beat up on Deadpool.
What do you guys think?
