The newly released trailer for Marvel's Avengers: Doomsday has generated significant excitement online, with comic book readers spotting several details that casual viewers may have overlooked. The film, due for release on 18 December 2026 alongside Dune: Part Three, will see the Avengers face Victor Von Doom, played by Robert Downey Jr, in what Thor describes as their greatest threat to date. While the full plot remains under wraps, the trailer offers clues that reward close comic book knowledge.

Among the details highlighted are more comics-accurate costumes for several characters, including Cyclops's classic blue-and-yellow suit and new looks for Mystique, Gambit and Namor, a departure from the X-Men films' earlier black spandex designs. The trailer also teases mismatched fights between characters, such as Gambit against Shang-Chi and Mystique against Yelena Belova, pairings that appear unbalanced when judged against the characters' comic book capabilities. Additionally, hints suggest a possible betrayal storyline involving Mystique, who is shown at the X-Men mansion amid suggestions she may align herself with the team.
