Marvel Studios has dropped the fourth official teaser trailer for Avengers: Doomsday (December 18, 2026), and this one is all about Wakanda and the Fantastic Four finally crossing paths in the MCU.

The teaser, released online January 13, 2026 after first playing in theaters with Avatar: Fire and Ash, focuses on the Wakandans preparing for war while introducing the Fantastic Four in a surprising way. Here’s the full breakdown, key moments, and what it means for the biggest MCU event yet.

Teaser Breakdown: Key Moments & Reveals

The clip opens with a somber voiceover from Shuri (Letitia Wright), now the current Black Panther:

“I’ve lost everyone that matters to me… The king has his duties to prepare our people for the afterlife. I have mine.”

We get quick shots of Wakandan leaders:

• Shuri in full Black Panther armor
• M’Baku (Winston Duke) as King of Wakanda (confirmed after his challenge at the end of Wakanda Forever)
• Namor (Tenoch Huerta Mejía) and Namora (Mabel Cadena) from Talokan in updated comic-accurate suits (black, collared design)
• The Dora Milaje ready for battle

The tone shifts to humor when Ben Grimm / The Thing (Ebon Moss-Bachrach) meets M’Baku:

• M’Baku: “King M’Baku, of Wakanda.”
• The Thing: “Ben. Yancy Street, between Broome and Grand.”

The teaser ends with the bold text: “The Wakandans and The Fantastic Four will return in Avengers: Doomsday.”

This is the first time the Fantastic Four (post-The Fantastic Four: First Steps) interact with the MCU mainline Earth – and it’s happening in Wakanda.

Major Changes & Confirmations

• M’Baku is King of Wakanda – Winston Duke’s character successfully challenged Shuri for the throne (post-Wakanda Forever).
• Namor’s New Suit – Comic-accurate black collared design, not just trunks.
• Fantastic Four Integration – Ben Grimm’s introduction confirms they’re crossing into the main MCU timeline after their 1960s debut. Pedro Pascal (Mr. Fantastic), Vanessa Kirby (Invisible Woman), and Joseph Quinn (Human Torch) are expected in the full film.
• Shuri’s Grief – Her voiceover references losing T’Challa, Ramonda, and others – setting up emotional stakes.

Why This Teaser Matters

This is the fourth character-focused teaser (after Steve Rogers, Thor, and X-Men). It confirms:

• Wakanda is a major battleground.
• The Fantastic Four are fully in the main MCU timeline.
• Crossovers are happening – Wakandans, Talokanil, and F4 teaming up against Doctor Doom (Robert Downey Jr.).

Fans are already theorizing:

• Wakanda as a strategic hub for heroes.
• M’Baku’s kingship leading to new alliances.
• Doom targeting Wakanda’s resources.

Avengers: Doomsday arrives December 18, 2026 – directed by the Russo Brothers.
