Robert Downey Jr. Will Not Return as Iron Man, Confirms Marvel Studios President

Marvel Studios president Kevin Feige confirmed that Robert Downey Jr. will not reprise his role as Tony Stark/Iron Man in the Marvel Cinematic Universe (MCU).
Feige stated that they would not 'magically undo' Stark's death in Avengers: Endgame, which marked the end of Downey Jr.'s tenure in the MCU.
Downey Jr.'s portrayal of Tony Stark/Iron Man was a key part of the MCU, with the actor appearing in 10 films from 2008 to 2019.
Despite rumors suggesting the potential return of the character through the multiverse, Feige's comments indicate that this will not happen.
The decision to not bring back Downey Jr.'s character is seen as a move to respect the emotional weight of Stark's sacrifice and the narrative arc of the MCU.
