Tony Stark’s place in the MCU may not be as closed off as Avengers: Endgame once made it seem.

A new theatrical version of Avengers: Endgame is set to arrive in September with additional scenes connected to Avengers: Doomsday, giving Marvel Studios a clean way to bring Robert Downey Jr. back into the story without reversing Iron Man’s death.

The move comes as Marvel prepares to push the Multiverse Saga toward its biggest chapter yet. Avengers: Doomsday is scheduled to unite the Avengers, the X-Men, and the Fantastic Four against Doctor Doom before Avengers: Secret Wars follows in December 2027.

Marvel’s current saga has moved faster than the Infinity Saga, which took 11 years to reach Avengers: Endgame. The Multiverse Saga began with WandaVision and is expected to reach Secret Wars after roughly six years.

Avengers Endgame Re-release Adds New Doomsday Link

Marvel Studios confirmed after its CinemaCon 2026 presentation that Avengers: Endgame will return to theaters in September with new scenes.

Those scenes are designed to connect directly with Avengers: Doomsday, though Marvel has not revealed what footage will be added or which characters will appear in it.

The timing has drawn attention because Avengers: Doomsday is expected to continue from the aftermath of Avengers: Endgame. That gives Marvel room to place new story material inside the 2019 film while keeping the original ending intact.

One possible route is Tony Stark. New scenes could revisit him before his death during the Battle of Earth, especially because Endgame left some parts of his time-travel breakthrough moving at a very quick pace.

The film already showed Stark solving the key problem behind the Avengers’ time heist, but it did not spend much time on what he may have understood about the risks. A re-release gives Marvel a chance to sharpen that part of the story.
