Black Panther: Wakanda Forever centers around 'The nation of Wakanda is pitted against intervening world powers as they mourn the loss of their king T'Challa,' according to the film's IMDb page.
Ryan Coogler wrote and directed the film and had to include a plot that ended the T'Challa storyline because actor Chadwick Boseman tragically passed away in 2020.
The actor, who was 43 years old, died of colon cancer. He never told the public he was sick, instead carrying on as if he did not have the disease.
Black Panther: Wakanda Forever is set for release on November 11.
Ironheart is a superhero who is a successor to Tony Stark's Ironman.
She wore huge goggles and appeared to have some machinery locked around her torso.
In addition, the posters showed off the villainous Namor (Tenoch Huerta), an underwater king who serves as both villain and an antihero in the comics.
Namora, Namor's cousin, appeared in another photo, a breathing mask over her vibrant blue face.
