Overview
- Marvel premiered a special look at Avengers: Doomsday that debuted at D23 and shows Robert Downey Jr. as Victor von Doom confronting Thor and stopping his attack.
- The trailer teases Doom's large-scale power and an army of Sentinels, putting mutants and X-Men–adjacent threats into the film's scope.
- Marvel's D23 display included a second, softer Doom costume and a damaged TVA set, which have been taken as visual clues about Doom's timeline ties or a transformation in his character.
- Fans on social media have offered competing theories—two Dooms, Doombots, or time-slipping—while reporters note those ideas remain unverified and based on trailer and exhibit discrepancies.
- Separately, Disney confirmed Downey will also reprise Tony Stark/Iron Man for two Disney California Adventure attractions opening in 2028, and Avengers: Doomsday is set to arrive in theaters on December 18, 2026.
