When Robert Downey Jr. returns to the MCU, here are some ruthless variations of Iron Man that the actor could get to play in his turn as a heel.
WHY ROBERT DOWNEY JR RETURNS AS DOCTOR DOOM
Robert Downey Jr. is poised to make a comeback in the MCU as Doctor Doom, despite being the face of the franchise for more than a decade as Tony Stark. Starting with his time in Iron Man, the actor became the definitive Tony Stark and one of the world's biggest stars when he led the Avengers. His ultimate sacrifice made him a legendary hero.
While fans seem to be on the fence about his appearance as Doctor Doom messing with his legacy as Iron Man, the character seems to have many variations in the comics that could make sense in the Multiversal Saga of the MCU. Some of his variants are so evil they put Hugh Jackman's Wolverine variants to shame.
Only Robert Downey Jr. may be a controversial casting two times in a row in the MCU. Casting the actor as Iron Man was a big task at the time for director Jon Favreau as he was still dealing with his legal issues. But his performance and the film's success at the box office cemented him as a resurgent star.
