From movies or from the comics? As far as the comics are concerned, many characters have assumed the roles of the famous super heroes. There hasn't been just one batman or one spidy. I like Steve Rogers as Captain America the most. The alternative versions not so much, though Bucky Barnes was good too.
I love the trinity, am a huge fan of Justice League. Also loved Nolan's treatment of Batman and Bruce in the trilogy.
And not exactly a superhero, but Loki kicks ass.
