Robert Downey Jr. is returning to the MCU, but Iron Man isn't. Instead, he'll be taking a new name and wearing a new mask--that of Victor von Doom, one of Marvel's greatest villains. RDJ kicked off the MCU and introduced superheroes to Earth-616 in 2008's Iron Man and ended his run as Tony Stark in 2018's Avengers Endgame. This could be the MCU's coolest moment--or its silliest.

Downey revealed his new role on the Hall H stage, coming out in a Dr. Doom mask and tearing it off to reveal his face to a surprised audience. His comment was simple: "New mask, same task."
