Marvel Zombies, Captain Britain, and more will be a part of the animated What If?'s first season on Disney+. And in a surprising twist, the show's Captain Britain will be the aforementioned Peggy Carter, voiced by Hayley Atwell.
"Almost every member of the MCU will be on it," said Marvel Studios President Kevin Feige. "Time is more than a linear path."
Feige showed footage from the series, including this still:

Other characters confirmed to be involved are Star-Lord, Bucky Barnes, and two versions of Steve Rogers - a Zombie Captain America and Iron Steve Rogers.
Here is Disney's official description of the show's portion of the panel:
"For Marvel Studios’ What If…? Hayley Atwell was on hand to greet the audience.
