This is a list of fictional universes in film and television, in which multiple works have occurred outside a single series or within a series across multiple media, either in an unnamed universe, a hypothetical future universe or in a fictional locale in our current present or past, while excluding any number of works that could reasonably be assumed to exist within the current understanding of our own universe or exist solely in a single series and medium.
A place in which supernatural phenomena exist, and supernatural evil can be challenged by people willing to fight against such forces and the setting of Buffy the Vampire Slayer and Angel series are set.
Universe that revolves around the fictional and non-existent town of Storybrooke, Maine, whose residents are actually characters from numerous fairy tales and other works that were bought into the present-day world by a powerful curse. In addition, the universe also covers the Enchanted Forest (where most of the characters originated from) and other worlds and realms that were affected by or after the events of the curse, including the events that took place in the spin-off Once Upon a Time in Wonderland.
A Hypothetical Universe that encompasses St. Elsewhere and numerous other television shows (primarily those produced by US network NBC) which are directly or indirectly connected through fictional crossovers and spin-offs.
