The only option to resurrect the MCU after Marvel's plans for Kang the Conqueror collapsed was to go larger. Marvel has been restructuring its business practices, and going forward, it will concentrate on its most successful properties and characters. Therefore, the introduction of doctor Doom is a fantastic way to set up the Multiverse Saga's climax, and Downey is an intriguing option to play the character.
 

Even though Downey's lengthy tenure as iron Man in the MCU may have caused some misunderstanding, the actor really has a history with the Marvel villain he will now portray. This is due to Downey's audition for the role of doctor Doom in the Fantastic Four films released in 2000. Given their previous collaboration and the actor's recent Oscar-winning villain performance in Oppenheimer, RDJ can elevate doctor Doom to a significant MCU force that necessitates cooperation from all of the heroes.
 

The explanation behind the MCU's casting of Tony Stark as doctor Doom is actually rather easy to understand. As Downey's Doom enters the Multiverse Saga, it's possible that he originates from a different reality and is attempting to take control of it all. This might lead to conflict with the Avengers and other heroes. There are strong rumors that Marvel's Fantastic Four reboot takes place in a parallel reality, meaning that in Avengers: Doomsday, Robert Downey Jr.'s doctor Doom may go from that universe to Earth-616.
