AI Summary

Avengers: Doomsday will formally introduce Doctor Doom to the Marvel Cinematic Universe, positioning him as a threat greater than Thanos. Although Robert Downey Jr.’s casting as Doom has generated excitement, the character has already appeared in MCU material via a post‑credits scene in VisionQuest, the animated short The Fantastic Four: First Steps, and an added scene in the re‑released Avengers: Endgame. Doomsday will be the first MCU entry where Doom can display the full extent of his powers against the entire Marvel universe.
