15. The Rocketeer

Here’s another blast from the past! The Rocketeer was basically the Iron Man of the 1930s. As the story goes, racing and stunt pilot Cliff Secord found a package left behind by gangsters who were being chased by the police. To his surprise, the package contained a rocket backpack. When he used the gadget, Secord became the Rocketeer and began fighting crime.

Sure, he wasn't a household name as many others on this list are. However, the Rocketeer is a font of references that literally transport the reader to other eras. Blame it on nostalgia or be grateful, but this character's adventures (some of which reference other pop culture heroes, such as Indiana Jones) are among our favorites.

The Rocketeer may not be a superhero, but he has all the traits necessary to be one. Plus, Alex Ross’ artwork is exceptional!
