It is almost confirmed now that Ms. Marvel (Iman Vellani), Kate Bishop (Hailee Steinfeld), and Cassie Lang (Kathryn Newton) will return in Marvel’s Avengers: Doomsday.
In the latest Alex Perez Q&A (via The Cosmic Circus), it is reported that Ms. Marvel, Kate Bishop, and Cassie Lang will appear in Avengers: Doomsday, though the full Young Avengers team won’t be formed before Doomsday—they may officially come together in Avengers: Secret Wars.
Billy and Tommy Maximoff, the twin sons of Wanda Maximoff (Scarlet Witch) and Vision, might reunite in Secret Wars in a way similar to the comics. Also, other young heroes like Tommy (Speed) could be involved, based on concept art leaks.
Recently, a leaked concept art piece shows Wong, Star-Lord, Ms. Marvel, Kate Bishop, Cassie Lang, Billy Maximoff, and his brother Tommy Maximoff from Avengers: Secret Wars. Check it out below.

The Russo Brothers will direct the upcoming Avengers movies, and Stephen McFeely will pen the script.
In a recent interview with The Playlist’s The Discourse podcast, Christopher Markus, the co-writer of Avengers: Infinity War and Endgame, said he couldn’t return to write Doomsday and Secret Wars because of his work with AGBO. He says that Marvel movies require a full-time, years-long commitment, which he couldn’t take on right now.
In Avengers: Doomsday, Robert Downey Jr. will play the role of Doctor Doom, Chris Evans as an Nomad, Tom Holland as Spider-Man, Pedro Pascal as Reed Richards, Joseph Quinn as Johnny Storm, Wyatt Russell as US Agent, Vanessa Kirby as Sue Storm, Florence Pugh as Yelena Belova, David Harbour as Red Guardian, Sebastian Stan as Bucky Barnes/Winter Soldier, Anthony Mackie as Sam Wilson/Captain America, Ebon Moss-Bachrach as The Thing, Benedict Cumberbatch as Doctor Strange, Chris Hemsworth as Thor, Elizabeth Olsen as Wanda Maximoff/Scarlet Witch, and Yahya Abdul-Mateen II as Wonder Man, Dafne Keen as Laura Kinney/X-23 and Kelsey Grammer as Hank McCoy/Beast, and Channing Tatum as Gambit.
Produced by Kevin Feige, Louis D’Esposito, and Russo Brothers will produce through their AGBO banner.
Avengers: Doomsday will be released on May 1, 2026, and Avengers: Secret Wars will come out on May 7, 2027.
