Robert Downey Jr. surprises Hall H to announce his return to the MCU as Doctor Doom.

The one surprise at Marvel‘s Comic-Con Hall H presentation Saturday it saved for last: Robert Downey Jr is returning to the Marvel Universe as Victor Von Doom in the Russo Brothers’ Avengers: Doomsday and Avengers: Secret Wars.

Along with the Russos returning to helm a two-part Avengers movies, they mentioned they’d need to tee up before Avengers: Secret Wars, a dream project of theirs, with another movie: Avengers: Doomsday. This clearly replaces Avengers: Kang Dynasty.

Essentially Kang Dynasty was deflated in the wake of the actor who played him, Jonathan Majors, getting fired from the MCU after being found guilty of reckless assault and harassment.

Since the start of the MCU with 2008’s Iron Man, Oscar winner Downey Jr. played that title character who finally died in Avengers: Endgame.

The Russo Brothers said tonight that they needed the right actor to move forward with another set of Avengers.

At that point an actor stepped onstage as Dr. Doom, with a steel mask and green cape and hood. Unmasking, it was none other than Downey, who many know as Tony Stark/Iron Man in the MCU.
