Avengers 4: 10 Theories From The Endgame Trailer

10. Tony Dies

Right off the bat, this trailer spends nearly half of its runtime with a space-stranded Tony Stark on the verge of death as he records an apparent goodbye message for his beloved Pepper Potts. This confronts the long-standing rumor that Tony Stark will wind up sacrificing himself for the team pretty head-on.

Honestly, it would make a lot of sense for Tony to die in this film. Robert Downey Jr.'s Tony is the one who started it all back in 2008 and one of the most effective and easiest ways for Marvel to really show fans just how much they mean business in terms of changing the roster of heroes moving forward would be to kill Tony Stark.

There's also ample amounts of evidence from previous films in terms of foreshadowing to back this theory up, from his almost self-sacrifice in The Avengers, to his dire dream sequence in Age of Ultron, to him striking a Jesus pose in the middle of the Infinity War poster.

It's safe to say he won't die on the Milano (as there are literally dozens of characters with ways to save him from this predicament in the MCU) but the sheer fact that Marvel continues to go to great lengths to make viewers think Tony could die is a solid sign that his time may finally run out in this film.
