The trailer depicts the technologically sophisticated African nation coming to terms with the death of King T'Challa, who was portrayed by the late Chadwick Boseman, just as the teaser did.
Also, it depicts battle with Atlantis and its ruler, Namor, who is portrayed by Tenoch Huerta, a newcomer to the series.
Marvel Comics #1, published in 1939, featured the character Namor, the Sub-Mariner, for the very first time.
"He is not addressed as king or commander by his people. He is known as Kukulkan. God of the feathered serpent, "M'Baku of Winston Duke is admonished. "Killing him might lead to an endless conflict!"
The strong character can be seen flying in the clip owing to his comic-accurate feathered ankles. Letitia Wright's Shuri says, "He's coming for the surface world."
The two kingdoms are seen fighting each other both on land and in Namor's home territory, the sea in the movie.
In the teaser, Riri Williams, played by Dominique Thorne, can be seen flying in her own Ironheart armour, which was modelled by Tony Stark's Iron Man outfits.
At the end of the trailer, a new Black Panther has assumed the role: A figure suddenly appears in the screen
wearing a distinctive vibranium outfit, but the helmet obscures the face, so we can't tell who it is.
At San Diego Comic-Con in July, 1st trailer for "Black Panther: Wakanda Forever" appeared. In "Wakanda Forever," a new enemy will be revealed for the Wakandans to defend their country against.
