What If? Marvel

Ever wondered what would have happened to Wakanda if Killmonger had defeated T’Challa? Or if Thanos’ finger snap had wiped out a completely different set of Avengers? Or what about if Marvel made an animated TV series with an all-star voice cast that could take up those questions and more?


Fortunately, we know the answer to that last question is a resounding yes, thanks to the unveiling of What If?, a Disney+ series set to inject some hypothetical chaos into the MCU.

When is Marvel’s What If…? series on TV?

The series is currently slated for a Summer 2021 release. Hopefully, the streaming service will be available in the UK by then…

What is Marvel’s What If…? 

Like the comic books of the same name, the animated show will delve into the MCU’s flagship moments and ask what would happen if they transpired another way.

It won’t be canon, but it will hopefully be a lot of fun. The anthology show could ask what would have happened if Peggy Carter became Captain America or how the world would have looked if Howard Stark made an Iron Man suit for Steve Rogers. The possibilities are endless.

The comic book series – launched in 1977 – also pondered on alternate timelines where Spider-Man joined the Fantastic Four and Hulk had the brain of Bruce Banner (something that later became reality in the comics and the MCU: see Endgame).

At Disney’s D23 conference, Kevin Feige debuted some footage from the series, including the story of how Peggy (voiced by live-action star Hayley Atwell) was enhanced by the super-soldier serum instead of Steve Rogers, and another where Bucky (Sebastian Stan) confronts a zombie Captain America.

The series is animated in a cell-shaded, animated style.
