At the DC All Access Panel at Denver Comic Con, writer Marguerite Bennett revealed that in the world of the DC Bombshells, based on the art of Ant Lucia and set in an alternate World War II, Bruce Wayne's parents were never killed. Instead they were saved by Batwoman…
So there is no Batman.
Bennett says that the "whole conceit of the story is that heroines came first, that there were no women who were derivative of their male counterparts",
The series begins in August.
