You forget that Spider-Man also borrows a lot of Superman keys..
We all know that Black Cat is the Marvel version of Catwoman. I still want her in a movie.
By the way..
Superman: Wears a red and blue suit, has super strength, laser eye vision, ice powers, flight, probably a lot more crap I don't know about since I don't actually read comics (>.<), never knew his parents, is the hero of Metropolis (which is practically New York), main villain is the head of a large company who wears a green and purple armor suit. Has Lois Lane.
Batman: Has a symbol based off of a creepy animal, uses his intelligence to make his combat gadgets, parents were killed which prompted him to fight against crime, he is the hero of Gotham City (which is practically New York), main villain is a crazy wacko who smiles a lot and wears a green and purple suit and uses 'gadgets' that look like clown/prank toys. Has Catwoman.
Spider-Man: Has a red and blue suit with a symbol based off of a creepy animal, has super-strength, and uses his intelligence to make his main tool (webshooters). Never really knew his parents, uncle was killed which inspired him to use his powers against crime. Is the hero of New York City, main villain is the crazy head of a powerful company who wears a green and purple battle suit, who also happens to be 'jokey'. Has Black Cat. Has Gwen Stacy and Mary Jane.
