The title for the fourth film has been the source of numerous speculations and fan theories as Marvel Studios confirmed that it is a separate story [VIDEO] rather than a continuation of "Infinity War."

CosmicBookNews [VIDEO] previously reported that their source "Richard" claimed that the title is "Avengers: Endgame" and it will close the chapter in Phase 3 in the MCU. The previous film featured Thanos trying to assemble the Infinity Stones so that he can initiate his plans for a universal genocide to bring balance. Earth's Mightiest Heroes, along with the Guardians of the Galaxy, tried to stop him and his army but failed in the end.

Thanos was able to change the universe and that resulted in the deaths of several heroes such as Spider-Man, Doctor Strange, Star-Lord, Black Panther, Scarlet Witch, and more.

New status for Hulk

CBR theorized that Bruce Banner and his monstrous persona will end up joining S.H.I.E.L.D. during the events of "Avengers 4" as both personas will act as one, resulting in a new version of the Incredible Hulk. Marvel Studios has always treated both Banner and Hulk as separate individuals, as Mark Ruffalo's character always referred to the jade giant as "the other guy."

The leaked character promo showed the Hulk wearing tactical armor similar to his "Doc Green" or "The Professor" persona in the comics. This suggests that this new Hulk has the genius intellect of Bruce and uses this suit as leverage when he faces Thanos.
