Robert Downey Jr. is reportedly set to portray Doctor Doom instead of Tony Stark/ Iron Man in the upcoming Avengers installment, often referred to as Avengers: Doomsday. The report focuses on speculation about the character shift, noting that fans were surprised when Tony Stark died in Avengers: Endgame in 2019.

In the sources provided, the main context is the established Marvel storyline in which Tony Stark’s death occurs at the end of Avengers: Endgame. The reported casting direction implies continuity of Downey’s involvement with the franchise while changing roles. However, the materials shared here do not include official confirmation details, production timelines, or statements from Marvel Studios or the actor, so the information is presented as a storyline development rather than an independently verified announcement.

Overall, the outlets converge on the same core claim: Downey is linked to Doctor Doom, with the character change framed against Iron Man’s prior on-screen death.
