Let's play a game: soon we will se a future state book called Superwoman with Kara Zor-El as the title character. Suppose than DC then decides than it is already time for Kara to graduate to Superwoman, specially considering the ending of the CW series and as a publicity stunt. Naturally, DC doesn't want to lose the name of the character and decides to use it for another character, publishing at the same time a Supergirl book and a Superwoman book. (Something hardly to see considering the status of DC today, but let that pass).

Who do you think could be the New Supergirl? Some previous character like Linda Lee (the earth angel), Cir-El or even Natasha Irons? Kara In-Ze maybe? Someone rescued from the silver age mythos? Laurel Kent? Laurel Gand?

Or could be someone completely new, like for example a daughter of Superman? A new inhabitant of Kandor? A clone of Kara Zor-El? SOmeone tottally not related to the kryptonian myths?
