TONY STARK EXITS STAGE LEFT IN ENDGAME
It's universally known that Robert Downey Jr. will exit the MCU as Iron Man in Endgame, although we don't know if he'll retire or be killed off. Judging from the Far From Home trailer, many fans are thinking that Tony will no longer be around in the MCU after the events of Endgame.
These theorists believe this is why we see Fury stepping into the mentor role, to carry out Stark's work by ensuring the kid becomes the best Avenger ever, and also to honor whatever sacrifice Iron Man made to save the world. Of course, Fury would see the boy as a soldier, so that's just an added bonus.
Stark's absence also looms large with Happy Hogan now seemingly dating Aunt May, possibly filling the father role Tony had adopted. Given that Stark was a pseudo-substitute for Uncle Ben, it's easy to see Spidey continuing to fill that hole in his life with these men.
ENDGAME CREATES A WARPED WORLD
Some fans believe Far From Home is actually occurring in a warped world similar to Marvel's Infinity Wars, and that everyone who died in Thanos' snap has been transported to a new world to live, perhaps within the Soul Gem. They even believe that Gamora's residing there, and that she brought with her all the souls the Mad Titan wiped out.
This theory stems from us seeing characters who died in the snap, or whose status was left unknown, like Fury, Happy and Aunt May, in the trailer. The warped world theory also blows open the door to the multiverse, and could easily allow the X-Men and Fantastic Four a way into the MCU. Either way, with a new world created, Far From Home as an alternate reality could be highly possible given that no one's depressed in the trailer, hinting they either forgot the snap or that both worlds are aware and accepting of each other, and that they're doing their best to safeguard both.
Opening July 5, director Jon Watts’ Spider-Man: Far From Home stars Tom Holland, Samuel L. Jackson, Zendaya, Cobie Smulders, Jon Favreau, JB Smoove, Jacob Batalon and Martin Starr, with Marisa Tomei and Jake Gyllenhaal.
