Half The Universe Is Dead?
As it stands now, half of all life in the MCU has stopped to exist. When Thanos snapped his fingers toward the end of Avengers: Infinity War, a tremendous lump of heroes got dusted away. These include any likes of Black Panther, Scarlet Witch, Spider-Man, and that’s just the beginning.
What The Fan-Theory Says:
As per one fan theory, everybody will, in the long run, make their return in Avengers: Endgame. However, their arrival will come at a colossal expense.
As the fan theory specifies, the new Avengers will return simply after the first Avengers — including Iron Man, Captain America, Hulk, Thor, Black Widow, and Hawkeye — sacrifice their lives with the goal that they can return.
Jumping into the theory, it says that the first Avengers may need to “link up” as the Guardians did in Guardians of the Galaxy to take the brunt power of the Infinity Stones as they take a shot at crushing Thanos. Consequently, the stones would expend them and reestablish order to the world.
What Other Theories States:
It’s been generally theorised that a portion of the original characters will finish up being killed sooner or later inside Endgame for a huge number of reasons.
As a matter of first importance, should the Avengers turn around the events of Infinity War with no sacrifice — physically or specifically — it’d remove a ton of the seriousness Infinity War depicted.
Also fueling theory of approaching deaths is the way that a portion of the actors are confronting expired contracts once Avengers: Endgame comes. In fact, Avengers star Chris Evans himself has implied that it’s the stopping point for some of the characters.
“Myself, Downey, Hemsworth, we all kind of started roughly at the same time, and I think we all, through Avengers 4, kind of wrap it up,” Evans said. “So at this point, I don’t know what’s next, but yeah, by 2019, that’s it.”
