Bruce This ultramasculine name keeps The Hulk undercover. But considering other famous Bruces include Bruce Lee, Bruce Springsteen, Bruce Willis, and of course, that other famous crimefighter, Bruce Wayne (AKA Batman), you can't go wrong with this classic, which means "plants, flowers and trees."
Tony Iron Man Tony Stark uses the most popular nickname for Anthony, a name that means "priceless." Anthony still ranks in the top 10 baby names in the U.S., so odds are the popularity of The Avengers will only push it higher on the charts. If you're looking for a girls' name, consider the feminine variation, Antonia.
Steve What's more all-American than a name like Steve? Captain America Steve Rogers uses this shortened version of Steven—a name that just dropped out of the top 100 a few years ago.
