Worlds' Finest writer Paul Levitz talked to CBR today about his upcoming Earth-2 transplants series. He talks about the scope of the book, what we can expect the style to be (a bigger type of book than say Huntress was,) and teases some of the potential supporting cast and guest stars, saying:
"You can't bring these characters to Earth without them being interested in who Superman and Batman and Robin and Supergirl are."Also, interestingly enough, he straight up confirms that this version of Helena Wayne is still Earth-2 Catwoman's daughter, and doesn't hesitate to answer questions referring to her as Bruce's daughter as well...
THEN WHY IS EARTH-2 BATMAN USING ESCRIMA STICKS!? GAAH.
