Avengers Doomsday: A Major MCU Return May Have Been Confirmed

Kathryn Newton Just Teased Her Avengers Doomsday Return, and the clue comes straight from her own social media. The Ant-Man and the Wasp: Quantumania star posted a Disneyland photo proudly wearing an official Avengers: Doomsday crew hat—an item that almost never appears publicly unless an actor is involved.

In this breakdown, we explore what this reveal means for the expanding Avengers Doomsday cast and how it connects to Marvel’s massive 2025 lineup announcement. While Marvel confirmed returning heroes like Thor and Ant-Man, plus the Fantastic Four and Thunderbolts, the Young Avengers were conspicuously absent. That’s why Newton’s apparent confirmation has sparked new theories surrounding Cassie Lang’s future.

Could Cassie be more than a cameo? With Doomsday teasers heavily emphasizing parenthood and multiversal sacrifice, her role may be emotionally critical—even if her screen time remains small. Fans have speculated through Cassie Lang theories and MCU Doomsday predictions that she may act as Scott Lang’s emotional anchor, or even as a catalyst for the film’s multiverse narrative.

Cassie has already proven herself in the fight against Kang, and her presence signals the MCU’s commitment to its next generation. Whether she steps up as a Young Avenger or fuels the emotional core of Doomsday, her return could reshape the road to Secret Wars.
