Chris Evans has reportedly signed up to return in Avengers: Secret Wars

Similarly, Iron Man perished in the battle with Thanos in Endgame. Tony Stark sacrificed himself to use the Infinity Gauntlet to undo everything that Thanos did with the "snap", which in turn rendered the hero un-revivable - at least at the time.

With Evans and Downey Jr. presumably on board for the Multiverse story arc finale, the only remaining member of the team who has not been enlisted to return is Scarlett Johannson. The Black Widow star stirred controversy when she filed a lawsuit against Walt Disney for breach of contract.

Johannson argued in the lawsuit that the company violated the terms of her contract by releasing Black Widow simultaneously in theaters and Disney+. However, with former Disney CEO Bob Chapek out, it would be Kevin Feige's task to fix the issue and facilitate Johannson's return.

Fans are divided by the new casting rumors as there are concerns that the return of Evans, Downey Jr., and Johannson to the MCU would downplay the ending of Avengers: Endgame. Others are excited to see all six of the original members possibly reuniting again.

There have also been rumors that Marvel plans to recruit all possible characters for a major set-piece battle similar to the events of Endgame. This includes characters that are not yet part of the MCU like the X-Men, as well as old characters that are either dead or have been replaced. Given that this is the Multiverse Saga, anything is possible.
