The 2026 edition of San Diego Comic-Con (SDCC) is almost upon us, and you know what that means: all manner of rumors and speculation about the surprises Marvel might have in store for us at its now-customary Hall H panel.

Marvel Cinematic Universe (MCU) diehards had expected the first official trailer for Avengers: Doomsday to be the focal point of the comic book titan's next presentation. With Avengers: Doomsday's main trailer released on Monday (July 20), though, Marvel must have something just as significant around which to center its forthcoming panel on July 25 at 5:30pm PT.
