Carbon Costume

Captain Carter is a character in Marvel’s What If…? streaming on Disney+. She stars in the first episode of the animated series, titled “What If…Captain Carter were the first Avenger?” In this universe, Peggy Carter receives the super soldier serum instead of Steve, thus becoming the hero dubbed Captain Carter. As opposed to Captain America’s stars and stripes, this costume uses a Union Jack as its emblem as a nod to Peggy’s background. She even has her own matching shield. Hayley Atwell, who portrays Peggy Carter in the movies, voices her animated counterpart. Spoilers: Hayley makes a cameo in Doctor Strange: Multiverse of Madness as a live action Captain Carter.

The Watcher (voiced by Jeffrey Wright) is a recurring character in the Marvel show, What If…? on Disney+. He starts each episode by explaining the many realities of the multiverse and introducing himself as the Watcher. He possesses abilities such as energy-manipulation and clairvoyance. But he never shares his origin, as he exists outside space and time, watching the events of different universes unfold. The Watcher never interferes, but when Ultron-Vision finds his observatory haven and threatens all realities, he must break this rule.
