Robert Downey Jr. is returning to Marvel — this time as an MCU villain.
Marvel and RDJ revealed the surprise at the end of the franchise's panel at Comic-Con on Saturday, Deadline and others reported.
Previously, Downey Jr. played Iron Man from 2008's Iron Man to 2019's Avengers: Endgame (when, not to spoil a five-year-old movie, but he died). Now, he'll play villain Victor Von Doom aka Doctor Doom in Avengers: Doomsday.
