In Doctor Strange 2 , Marvel’s sacrificed superheroes are very likely to return thanks to the way the multiverse operates in the film.

Doctor Strange in the Multiverse of Madness (Doctor Strange 2) has been officially produced by Marvel in the summer of 2019 and is expected to release in May 2020. However, due to the effects of the Covid-19 epidemic, the film was delayed for release until January 5, 2020. 

Doctor Strange 2 is also an opportunity for Marvel Studios to bring some of the non-existent characters in the main timeline of the Marvel movie universe (MCU).

Iron Man

Stephen Strange and Tony Stark did not know each other even though they lived in New York . The couple are tied together by the threat that Thanos poses in Avengers: Infinity War . Together they battle superhero teams on the planet Titan, home of Thanos. Strange knew Tony’s tragic fate five years before the events of Avengers: Endgame.

Now Marvel Studios can exploit a variety of scenarios, maybe even develop ideas for Strange wearing Iron Man suits. This is a scene that was filmed on the set of Avengers: Infinity War but has been cut off. Doctor Strange 2 can recreate the video in a way that fits the narrative of the sequel. On the other hand, the sorcerer can also travel through countless parallel realities for the next mission and meet another version of Tony Stark.

Captain America

Captain America decided to retire and pass the shield on to Sam Wilson. Captain America can go back in time to live with Peggy Carter or create a branched timeline. Doctor Strange 2 also has the ability to go to the alternate timeline where the Captain marries Peggy and interact with the new version of Captain from another universe.

Vision

Besides the appearance of Scarlet Witch,  Doctor Strange in the Multiverse of Madness  will also have links to WandaVision . According to Screen Rant , Doctor Strange played an important role in bringing the twins of Wanda and Vision, Billy and Tommy Maximoff, in the comics to the screen.

Vision is not among those resurrected in Avengers: Endgame , so how he returns is still a big question. As time goes on, WandaVision will debut first and it’s likely that the wizard’s appearance in WandaVision may be related to the content in Doctor Strange 2, helping explain the question of how Vision can return. OK.

Thanos

Thanos can appear in Doctor Strange 2 when he is the last to use the Time Stone. The stones have been destroyed at the beginning of Avengers: Endgame and are likely to trigger events in Doctor Strange 2 , because they play an important role in maintaining the status quo.  

With Captain America returning the stones they received at the respective time and place, Doctor Strange lost his main weapon. He can travel through multiple universes and meet Thanos in hopes of obtaining the Time Stone once more, in order to protect the reality of which he is responsible.

Ancient One

With the multiverse being an important part of Doctor Strange 2 , Ancient One is likely to return to help and guide Doctor Strange when the witch takes on his new mission.
