Fans watching the newly released Avengers: Doomsday trailer believe Marvel has deliberately edited a key group shot to hide certain characters, continuing the studio's long-running practice of using misleading trailer edits to protect plot secrets. The shot in question shows the Avengers, New Avengers and Fantastic Four assembling before confronting Robert Downey Jr.'s Doctor Doom, but viewers have spotted what looks like an edited gap where Doom and Steve Rogers appear to have been digitally removed, fuelling speculation about a twist in which Doom initially poses as an ally before betraying the team.

Fans have floated several theories about who might be concealed, including Doom himself, an unannounced reunion between Loki and Thor, or surprise appearances by characters such as Spider-Man, Doctor Strange, Captain Marvel or the Eternals. The article notes Marvel has form here, having previously hidden Andrew Garfield and Tobey Maguire in a Spider-Man: No Way Home trailer, inserted a non-existent Hulk shot into the Infinity War trailer, and altered footage in Endgame and Thunderbolts*/The New Avengers to mask plot details. A further theory suggests the bearded, long-haired Steve Rogers seen in the new trailer may not be the same version glimpsed earlier with a baby, hinting at a possible villainous alternate version of the character.
