Photos from the studio's Avengers: Doomsday display have surfaced online, offering our best look yet at several costumes from the upcoming Marvel event film, along with a few intriguing surprises that are already fueling fan theories. The display is anchored by a new Avengers: Doomsday-themed Marvel logo, but it's the costumes that are grabbing everyone's attention. Marvel also revealed our first official look at a Sentinel head, and it couldn't look much closer to the comic book version. After last year's schedule shakeup, Avengers: Doomsday is now set to hit theaters on December 18, 2026, while Avengers: Secret Wars will follow on December 17, 2027. If this SDCC display is any indication, Marvel is finally starting to pull back the curtain, and there's a lot more waiting to be revealed before Avengers: Doomsday arrives in theaters.
