Marvel is reportedly working on an animated series based on the What If comics for the soon-to-be-launched Disney+ streaming service. The What If series are one-shot adventures that exist outside of the comics canon and ask questions like "What if Loki had found the hammer of Thor?" or "What if Spider-Man didn't become a crimefighter?" The series will operate under the same idea, giving different takes on what has happened in the Marvel Cinematic Universe canon.
The series is reportedly being developed by Kevin Feige and Marvel Studios. And we could expect some of the bigger Marvel stars to come in and voice their characters. This show will join the already-announced Loki series and other rumoured Marvel shows that'll revolve around characters like Vision and Scarlet Witch and another with Falcon and the Winter Soldier.
