Avengers: Doomsday builds its biggest crossover yet with the Wakandans and the Fantastic Four.

Marvel’s fourth release teaser for “Avengers: Doomsday” widens the board again, placing Wakanda at the center of the movie’s next big crossover. The spot moves fast, but it delivers a clear message: the Marvel Cinematic Universe is stacking worlds on top of worlds, and old borders are no longer holding.
The teaser opens on a vast desert landscape, serving as a mood-setting backdrop for quick flashes of Tenoch Huerta Mejía as Namor, while Mabel Cadena appears as Namora. The clip then pivots to the Wakandans, where Letitia Wright returns as Shuri in her Black Panther role. Winston Duke also appears as M’Baku, who is framed as Wakanda’s king in the teaser. The tone leans serious, with Wakanda presented less as a victory lap and more as a nation bracing for impact.
Ben Grimm Enters the Picture
The teaser’s headline moment is the introduction of the Fantastic Four into this corner of the MCU. Ben Grimm, played by Ebon Moss-Bachrach, arrives and meets Shuri and M’Baku. The scene reads like a first contact between super-powered allies who have not shared the screen before.
How This Connects to the Earlier Teasers
This fourth teaser continues Marvel’s steady rollout strategy, which has used previous spots to spotlight different corners of the saga. Earlier teasers leaned into Captain America, followed by a Thor-focused entry, and then an X-Men-centered tease with Cyclops, Professor X, and Magneto that signaled mutant involvement in the next phase. Teaser number 4 adds another lane by tying Wakanda to the Fantastic Four while keeping Talokan present in the background.
Avengers: Doomsday in theaters on December 18th, 2026.
