Trivia:
Originally, the villain was named Peppa.AVI, who would've used her "epik demon powah!" to tear the multiverse apart. Was scrapped because it was a dumb idea; Nova thought it would make it too unserious.
SuperNova28 considers this one to be her favorite due to "the mixture of the goofy charm the first 3 had, and seriousness".
The MPA wouldn't have existed if it wasn't for this movie, as the entire reason the PPCU has a focus on the multiverse is because Nova thought it would be funny to reference "Doctor Strange in the Multiverse of Madness".
