According to one theory, Doctor Strange saw multiple Avengers victories over Thanos in Endgame, but he sacrificed Iron Man for the survival of the universe.
If more than a year after the release of Avengers: Endgame , fans are still wondering if Robert Downey Jr. could reprise his role as Iron Man in the MCU, the answer is still the same: it’s no. Tony Stark sacrificed himself to wipe out Thanos and save the planet, and while it saddens us a lot, his loss could be the entire universe’s only chance for survival according to a new theory. Based on Screen Rant’s thinking, Doctor Strange could have been lying when he told the Avengers that they had a one in 14,000,605 chance of beating the Mad Titan. The hypothesis maintains that the Sorcerer Supreme would have seen several other situations in the future in which the villain would be defeated, only the one where Iron Man sacrificed himself would be the only one that would make the future sustainable . The reason ? With Stark Industries, Tony Stark has already done too much damage: with each new innovation, bad guys were created, it was time to stop it.
