The Avengers: Endgame trailer starts on a grim note as we see a dying Tony Stark drifting through the cosmos in the Guardians’ ship, but we have a theory on how he might survive his predicament, and it’s centered around the love of his life, Pepper Potts.
In the comics, Pepper has her own version of the Iron Man armor equipped with protective gadgets to save people, which is why she takes up the superhero name Rescue.
