Avengers: Age Of Ultron - Ranking The Powers Of Earth's Mightiest Heroes

4. Captain America

The super soldier serum flowing through Captain America's veins make him especially strong, resilient, and agile in a battle. He may not have a magic hammer or wear a powerful suit of armour, but Steve Rogers is someone you should want to lead you into battle, and is without a doubt one of the toughest and strongest members of Earth's Mightiest Heroes. His shield may come in handy (especially as Tony Stark has added a magnet to it in Avengers: Age Of Ultron which means Rogers can call it back to him at any time), but Captain America doesn't need gadgets or a costume to kick some serious butt. He's squared off with both Thor and Iron Man and come out unscathed, and should really take it to Ultron. Of course, the fact that he's the only member of The Avengers to be able to slightly move Thor's hammer - because he's worthy, not just strong - might be an indication that the sequel is going to show just what Cap is truly capable of if he gets to actually wield it.
