The very first trailer of Marvel's What If...? animated series is finally out, and it has brought back Chadwick Boseman's T'Challa, aka Black Panther. The animated series talks about the story of alternate realities and what would have happened to the comic world if certain realities were changed or altered in some way or the other.

During the Disney Investor presentation, Kevin Feige shared the very first trailer of Marvel Studios' first animated series What If...? The animated show is based upon the comics of the same name where alternate realities are imagined. For example, what would have happened if, instead of Steve Rogers, Howard Stark chose Peggy Carter to become the super-serum soldier; or if Bucky Barnes had to fight a zombie Captain America.

The animated show would be narrated by The Watcher (voiced by Jeffrey Wright). In the Marvel world, The Watchers are a race of extraterrestrials whose purpose is to watch over the multiverses. However, they are very much different from TVA, which is going to make a debut in the Disney+ Loki TV show. The Watchers appeared briefly in Guardians of the Galaxy Vol. 2.
