Avengers: Doomsday plot

The plot for Avengers: Doomsday is being kept under wraps, and Marvel have done well to keep all the details of the upcoming film a secret.

What we do know, however, is that Robert Downey Jr. will be returning to the Marvel Universe. Not as Iron Man (who we saw die in Avengers: Endgame) but as the villain of the film, Doctor Doom.

The announcement was made in July 2024 at SDCC, where Robert appeared on stage to confirm his new Marvel role.
