Earth-1199999 is a universe heavily inspired by the mainstream Marvel Cinematic Universe. As such, most of the films are inspired by their MCU counterparts, though how closely inspired they are will vary from film to film. The main difference between the universes is that, in this version of the MCU, Marvel Studios retained the rights to all its characters from the beginning.
