While the Marvel Cinematic Universe has adapted the vast majority of Marvel Comics superheroes to live-action, the DC Universe still has a long way to go. Although longtime DC Comics readers are familiar with iconic and obscure heroes alike, general audiences have yet to be introduced to characters like Plastic Man or Powergirl. It's possible that when the day comes for their live-action adaptations, they get promoted from B-rated characters to A, much like Iron Man when Robert Downey Jr. stepped into the role.
