Earth-Prime, in which all five shows and two upcoming will take place on. However, since Earth-Prime is an amalgamation of three universes and with a brand new history, as of characters brought over from Earth-38 and Earth-BL along with Earth-1 characters. If a person existed on more than one of those Earths, would all of that persons histories merge into one when this new multiverse was created?
