The Endgame title surely confirms another clue. An early clue about the title came from the Russo brothers who ruled the Infinite War. A theory of fans claims that the film title is Avengers: Anarchy, based on a thorough study of a photo shared by Russos on Twitter.
After the Infinity War has spent much of the time with the characters introduced since the first Avengers movie, the fourth Avengers movie will probably find six nuclei that will correct the mistakes of Thanos’ world movement. As for the new characters, Avengers 4 will be the first in the series with Captain Marvel, who will debut in his own film.
