What If…? is Marvel’s fourth series on Disney+, but don’t expect it to be like WandaVision, The Falcon and the Winter Soldier, or Loki. For one, What If…? is the MCU’s first animated show. It also just might be Marvel’s most bonkers show yet.

That’s because What If…? takes iconic MCU moments and adds a reality-bending twist. We’ll get to see what would have happened if Peggy Carter had taken the super soldier serum instead of Steve Rogers, or if Yondu had brought T’Challa to space instead of Peter Quill.

Also, there are Marvel zombies, and a mysterious figure known as the Watcher who…watches over everything that’s ever happened. The possibilities for these alternate realities are endless (and very exciting). Many Marvel cast members return to voice their characters, including Chadwick Boseman in his final performance as T’Challa/Black Panther.

What If…? starts streaming August 11 on Disney+, with new episodes every Wednesday.
