These are the latest photos of What If...? merchandise to leak online ahead of the show's premiere on Disney+ this summer. A separate image revealed a poster featuring multiple characters from the series as part of a group identified as the "Guardians of the Multiverse." Among those depicted were Uatu and "Party Thor," along with Erik Stevens/Killmonger; alternate universe versions of Natasha Romanoff/Black Widow, Stephen Strange and Gamora; "Captain Carter," a new iteration of Peggy Carter who's taken the Super-Soldier Serum; and T'Challa as Star-Lord, voiced by the late Chadwick Boseman.

Inspired by the Marvel Comics anthology series of the same name, What If...? explores what might've happened if key moments in the MCU's history had played out differently. Creator and executive producer A.C. Bradley has avoided revealing too much about the show beyond what's already been confirmed, including how superheroes like "Party Thor" differ from their MCU counterparts. However, he did confirm there would be "more than a few surprising MCU cameos... and characters can and do pop up in more than one episode!"
