Avengers 4: 8 Major Plot Predictions
5. The Original Avengers Die For The New Avengers
It's no accident that the complete, "original" Avengers crew - Iron Man, Thor, Cap, Black Widow, Hulk, and presumably Hawkeye - are left standing at the end of Infinity War.
The decision of which characters turned to dust and which were left unscathed was certainly one that writers Christopher Markus and Stephen McFeely, the Russo Brothers and Marvel Studios discussed at great length, so there's definitely something we can read into here.
Characters like Black Panther and Spider-Man are definitely coming back, make no mistake, but how will they be brought back? That's where things get interesting.
Sacrifice was a big theme in Infinity War, and the movie already touched upon the idea of exchanging a soul for a soul when Thanos sacrificed Gamora to retrieve the Soul Stone. So what if this idea is something that Avengers 4 expands upon?
Maybe the dead Avengers are all trapped in some sort of soul world/realm, and the living Avengers must trade their souls in order to bring their friends back - essentially "passing the torch" to the new generation of heroes.
It's not hard to imagine Tony Stark giving his life to save Peter Parker, and if the Avengers' aforementioned time travel mission isn't able to save everybody, this could be one way for the team to undo the horror of Thanos' finger snap.
