Sam Wilson can't continue his past manifestation as the Falcon since he has been raised to the place of Captain America close by Steve Rogers.
Sam Wilson has been effectively searching for some taken vibranium in his ability as Captain America.
He has followed it as far as possible from the southernmost mark of the United States to Latveria,
where Dr. Destruction condemns him for abusing his region.
Sam enters Wakanda secretly to see what he can find once the path becomes ineffective. Dark Panther isn't satisfied to find them
there without approval since it just so happens, Crossbones has concocted a snare for him to fault him for attacking the African country.
