5. Justin Hammer
Sam Rockwell rules in movies. He's so great. And he's even super great in Iron Man 2, a movie that isn't very good.
But his performance as Justin Hammer is pretty killer. A knock-off imitation Tony Stark is a great idea, and the specific pieces in play here really do work. Dear Lord, I love his bad fake tan. It's such genius character work.
Again, Hammer’s one of the few MCU villains who escape death at the end of their movies. Instead, he was arrested for his crimes involving Whiplash and the Hammer Tech drones, and wound up in Seagate Prison.
We actually saw him again after that! He popped up in the All Hail the King Marvel One-Shot, still an inmate in the prison. It's very likely that he's being kept out of general population, since his presence in the jail seemed more like a rumor during Luke Cage flashbacks.
