The fourth teaser trailer for Avengers: Doomsday has leaked after a theater screening, with Polygon noting the sneak peek places Wakandan and Talokanil forces on screen alongside a member of the Amazing Fantastic Four. The clip opens with Shuri, the current Black Panther, joined by Wakandan King M'Baku and the Dora Milaje, before cutting to glimpses of Namor and Namora from Talokan. A line of voiceover from Shuri precedes a moment of tension: “I’ve lost everyone that matters to me.” The footage appears to set the stage for a renewed intersection between Wakanda and other corners of the MCU, with hints of a Fantastic Four arrival threaded into the Doomsday narrative. It also teases a potential encounter between the Thing and M'Baku, a moment that suggests Ben Grimm could be stepping into the wider Doomsday equation.
From there, the trailer footage shows M'Baku introducing himself to Ben Grimm with a succinct descriptor: “King M'Baku, of Wakanda.” Grimm replies with a quintessential Yancy Street greeting: “Ben. Uh, Yancy Street, between Broome and Grand.” The exact placement of this exchange within the film remains unspecified, but the sequence strongly implies the Fantastic Four’s involvement may be tied to the Doomsday events unfolding across Wakanda and Talokan. The theory: the Thing and possibly other FF members land in or travel through Talokan as part of their MCU arc, which could connect to Thunderbolts’ post-credits setup and the broader multiversal chessboard Marvel has been building.
Marvel Studios has continued a pattern of releasing character-focused teasers that spotlight specific corners of the cast, and Doomsday is no exception. The roster cited in coverage includes Robert Downey Jr. as Doctor Doom, with returning Marvel veterans and a broad cast that appears to feature Chris Evans as Steve Rogers, Chris Hemsworth as Thor, Anthony Mackie as Captain America, Sebastian Stan as the Winter Soldier, Letitia Wright as Shuri, Paul Rudd as Ant-Man, Wyatt Russell as U.S. Agent, Vanessa Kirby as Sue Storm, Pedro Pascal as Mister Fantastic, Joseph Quinn as the Human Torch, Simu Liu as Shang-Chi, Florence Pugh as White Widow, Kelsey Grammer as the Beast, Lewis Pullman as Sentry, Danny Ramirez as Falcon, David Harbour as Red Guardian, Hannah John-Kamen as Ghost, Tom Hiddleston as Loki, Alan Cumming as Nightcrawler, Rebecca Romijn as Mystique, and Channing Tatum as Gambit.
A broader, more traditional Avengers: Doomsday trailer is rumored to land in tandem with Super Bowl LX on February 8, following Marvel’s usual release cadence for high‑impact teases. If the studio adheres to its playbook, the fourth Doomsday trailer is expected to debut officially on YouTube on Tuesday, January 13. Avengers: Doomsday arrives in movie theaters on December 18, with a follow-up, Avengers: Secret Wars, planned for December 2027. These dates anchor a film that, at least in leaks, is leaning into a cross‑section of Marvel’s sprawling lineup, pairing Wakanda’s leadership with Namor’s realm and the ever‑expanding Fantastic Four mythos.
