The release of Avengers: Doomsday is less than a year away, and excitement is building rapidly. With two trailers already out and more coming soon, fans are incredibly eager to see the film. For months, the only official content available was a four-hour video of empty chairs on set, but even that confirmed many of the actors who would be in the movie. Now, rumors and speculation about potential surprise appearances by other Marvel stars are adding to the buzz around Avengers: Doomsday.
With so many actors potentially appearing in upcoming Marvel movies, including Avengers: Secret Wars, one rumor is gaining traction. Actress Kathryn Newton, who played Cassie Lang in Ant-Man and the Wasp: Quantumania, recently shared a puzzling post on social media. If it wasn’t meant to mislead fans, it might hint at a significant, unannounced detail about Avengers: Doomsday and who will be in it.
Avengers: Doomsday May Finally Assemble the Young Avengers

A recent social media post by Kathryn Newton has sparked excitement among fans. She shared a seemingly ordinary photo wearing a hat from the set of Avengers: Doomsday. Because the official cast reveal video didn’t show a chair for her, many believe this confirms she’ll be returning to her role as Cassie Lang in the movie. This has led to speculation that other young heroes from the Marvel Cinematic Universe might also appear in the film alongside her.

Marvel Studios has long wanted to create a Young Avengers team, and recent hints suggest it’s finally happening. The end of 2023’s The Marvels showed Kamala Khan and Kate Bishop teaming up, signaling the start of a new group of heroes. While the full lineup for the Marvel Cinematic Universe remains unknown, characters like Ironheart, Patriot, America Chavez, and Speed are strong possibilities. This new team could even play a role in a future Avengers movie, potentially titled Doomsday.
Okay, so everyone’s buzzing about Kathryn Newton hinting at the Young Avengers in the upcoming Avengers: Doomsday movie, but I’m not entirely convinced it’s a done deal. Remember the tiny chair they showed off to confirm Paul Rudd’s return as Ant-Man? Well, his daughter Cassie is also in the film, and it’s possible her role is only connected to her dad, and not necessarily to any potential Young Avengers team. Honestly, right now it’s all just guesswork. Take Newton’s social media post with a grain of salt, folks – it might end up being a total red herring! We just don’t know for sure yet.
