New promo art for Avengers: Doomsday has surfaced on social media, offering what could be an early look at the film’s enormous character roster.
The artwork highlights Marvel’s merging of the MCU, Fox’s X-Men, and other corners of the franchise under the guidance of the Russo brothers.
Who’s Featured
The art shows Doctor Doom alongside the Fantastic Four, with Mr. Fantastic, Invisible Woman, Human Torch, and Thing all present.
X-Men veterans also appear, including Magneto, Beast, Xavier, Cyclops, Gambit, and Nightcrawler, while Mystique is featured as well.
MCU regulars Bucky Barnes, Yelena Belova, Red Guardian, Shuri, Sam Wilson’s Captain America, Shang-Chi, M’Baku, Ant-Man, Loki, Falcon’s successor Joaquin Torres, Namor, Sentry, Ghost, and U.S. Agent are also depicted.
Franklin Richards is shown too, suggesting Marvel may be moving quickly to establish the Fantastic Four’s legacy.

Costume Notes
Some details in the designs stand out. James Marsden’s Cyclops is drawn wearing the iconic blue-and-yellow costume from the classic X-Men animated series, marking a clear nod to fan nostalgia.
Chris Hemsworth’s Thor looks close to his Infinity War appearance, sporting short hair and armor reminiscent of that period rather than his more recent costumes.

What It Means
While promo art doesn’t always represent what will appear on screen, the sheer scale of the lineup hints at Marvel’s ambition for Avengers: Doomsday.
With Robert Downey Jr. returning as Doctor Doom and so many major characters converging, the film is shaping up to be the MCU’s most expansive crossover since Endgame.
