Actor Anthony Mackie offered insight into Chris Evans' returning character in Avengers: Doomsday, clarifying that whilst Steve Rogers will appear in the film, he will not resume the Captain America role. Drawing from comic book source material, Mackie hinted the character may follow an alternative trajectory in the adaptation.

In Marvel comics, Nomad represents the original Captain America's identity after he abandons both his title and association with the United States government following disillusionment with it, freeing him to operate as a hero without national constraints. The specific manner in which this narrative element will manifest in the Marvel Cinematic Universe remains unconfirmed, particularly given that the character was previously depicted as an elderly man.
