In the multiverse, anything is possible. There have been many rumors that Marvel Studios has instantly tried to bring back its iconic Infinity Saga characters to undo whatever the internet has been complaining bout. As much as Phase 4 and 5 have been a bit more varied in their quality, there’s certainly something curious about the amount of rumors people still clamor around.
In an interview with Vanity Fair, however, Marvel Studios CEO Kevin Feige has once again highlighted that they are not going to undo the big heartbreaking death of Tony Stark’s death in Avengers: Endgame. He gave the following statement that they won’t “magically undo it in any way.”
We are going to keep that moment and not touch that moment again. We all worked very hard for many years to get to that, and we would never want to magically undo it in any way.Kevin Feige
However, we should keep in mind that this doesn’t mean Robert Downey Jr. could still return in some form in the franchise. They could have him take on a different role and still appear in the multiverse franchise. The fact they haven’t used the actor since they started the multiverse storyline showcases that they are holding back and likely only reintroduce a version of him if it fits the story thematically.
