Overview

• Viral images of an X‑Men lineup and a supposed first look at Robert Downey Jr. as Doctor Doom were identified as AI creations, including by the original posters and digital artist BossLogic.
• Reporters and community testers point to verification tools and tells—such as Google SynthID results, incorrect social‑media handles, and flawed device designs—to spot fabricated pictures.
• Kelsey Grammer said he interacted with Chris Hemsworth’s Thor, “sort of” shares a scene with Downey’s Doom, and worked with Pedro Pascal’s Mister Fantastic, per Entertainment Tonight comments reported by GamesRadar.
• Marvel has not released official costume photography, and outlets suggest a first teaser could arrive next month, potentially attached to Avatar: Fire and Ash, though this has not been announced by the studio.
• Avengers: Doomsday remains slated for December 18, 2026, as a large ensemble featuring legacy X‑Men, the Fantastic Four, multiple Avengers lineups, and Downey as Doctor Doom.
