The latest updates and spoilers for "Avengers 4" reveal new details about its title and one founding member will join S.H.I.E.L.D. during the story. Express UK reported that the possible movie title will be revealed during the "Avengers: Infinity War" DVD and Blu-ray releases.

ComicBookResources came out with a theory that Bruce Banner (a.k.a. The Hulk) will likely become an agent of S.H.I.E.L.D. in the Marvel Cinematic Universe based on his character design from the leaked promo image of the fourth film. The sequel will feature the surviving heroes last stand against Thanos in order to save the universe and their fallen friends.

Fourth 'Avengers' title hinted in 'Infinity War' Blu-ray release

According to Express UK, Hollywood analyst Jeremy Conrad speculated that the DVD and Blu-ray releases of "Avengers: Infinity War" might reveal the official title of "Avengers 4." Conrad stated that the digital release for "Infinity War" will be on July 31, while the Blu-ray release is scheduled on August 14. He is positive that Marvel Studios may have put a featurette about the fourth film in as extra content.

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 rather than a continuation of "Infinity War."

CosmicBookNews 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.
