In addition, multiple continuities are visited in the comic book series "What If", "What The--?!" (formerly "Not Brand Echh") and "Exiles". The concept of continuity is not the same as a "dimension" or a "universe"; for example, characters like Mephisto and Dormammu hail from parallel dimensions and Galactus from the universe that existed before the Big Bang which began the current universe, but they all nevertheless belong to the Earth-616 continuity (where all the parallel dimensions and alternate universes seem to be connected to the same main timeline). A continuity should also not be confused with an imprint; for example, while the titles of some imprints, such as Ultimate Marvel, take place in a different continuity, some or all publications in other imprints, such as Epic Comics, Marvel MAX, and Marvel UK, take place within the Earth-616 continuity.
