You all know the heroic adjectives of Marvel. The Incredible Hulk. The Invincible Iron Man. The Mighty Thor. The Spectacular Spider-Man. The Uncanny X-Men. But from what I can tell, the big-name Captain America doesn't get one of those. It could be that the rank of Captain counts to this purpose, but most of the others have names that work perfectly fine without them (though the Fantastic Four might run into a snatch with this). And the last time I checked, America isn't an adjective.
So does Captain America have one of these heroic adjectives, either in the title of his books or used for him in said books? Or have the writers neven given him one, possibly because he predates the others?
