Avengers: Endgame will see Earth's Mightiest Heroes going up against Thanos in order to reverse his snap, which wiped out half the life in the universe. Taking on the Mad Titan is going to require sacrifices, and a new theory suggests Tony Stark might have to sacrifice his own child in the film.

This theory is definitely related to time travel, which many figure will play a role in the upcoming film. We think that Tony Stark might have to sacrifice the life of his own child by creating a new timeline.  There are a lot of indications that Pepper Potts might be pregnant in Infinity War, and storywise, there's a good reason Tony might have to sacrifice himself.

Check out the video below for more on the theory Tony will have to sacrifice his child in Endgame.

There are a lot of fan theories that figure Tony will die in Endgame. However, at this time, there's no such death confirmed. We did get a brief glimpse of Happy Hogan in the trailer for Spider-Man: Far From Home, but Tony was nowhere in sight. It's also possible Tony might take more of a backseat in the MCU going forward and only rarely have a cameo. Still, fans will have to wait until Endgame releases later this month to see what happens to the hero who started it all.
