Warning: This post contains potential spoilers for Avengers: Doomsday.
The fourth and final trailer for Marvel’s Avengers: Doomsday has leaked online after it began playing in theaters.
The trailer opens with Shuri (Letitia Wright) approaching Talokan. We briefly see Namor’s (Tenoch Huerta Mejía) new look. It then cuts to Shuri walking alongside M’Baku (Winston Duke) as they arrive to meet Ben Grimm, a.k.a. The Thing (Ebon Moss-Bachrach), aboard a Wakandan aircraft. The scene then cuts to black. The Wakandans and the Fantastic Four will return in Avengers: Doomsday.

The description follows:
Shuri: “I’ve lost everyone that matters to me. A king has his duties—to prepare our people… for the afterlife. I have mine.”
M’Baku, introducing himself: “King M’Baku of Wakanda.”
Ben Grimm: “Ben. Yancy Street, between Broome and Grand.”
It has been confirmed that Mabel Cadena will officially return as Namora in Avengers: Doomsday.

Directed by the Russo brothers from a screenplay by their longtime collaborator Stephen McFeely and Michael Waldron.
