Avengers: Doomsday Theory Hints at Marvel Trickery, But Spider-Man: Brand New Day Might Have Ended the Debate

Theory Briefing

• A visible gap in the Doomsday trailer's hero lineup is the core evidence fans cite for a hidden character being digitally removed before release.
• Marvel has a real precedent for trailer edits — past MCU trailers did remove details later revealed in the films, lending the theory genuine credibility.
• The same "edited-out character" theory circulated for Spider-Man: Brand New Day's Hand attack scene, and turned out to be completely false.
• Competing guesses for the mystery figure range from Doctor Doom himself to Loki disguised as Steve Rogers to the long-hoped-for return of Scarlet Witch.
