After the launch of the Superman/Batman comic book series, Executive Editor Dan DiDio had been looking for a way to simplify the Supergirl character from her convoluted post-crisis history; the simplest version of course, was Superman’s cousin. Jeph Loeb and editor Eddie Berganza found an opening to reintroduce the character following the conclusion of the first story arc of Superman/Batman.
The modern version of Kara Zor-El made her debut in Superman/Batman #8 (2004). Kara takes the mantle of Supergirl at the conclusion of the storyline. The Supergirl comic book series would later be relaunched, now starring Kara Zor-El as “The Girl of Steel”. The first arc of the new series was written by Jeph Loeb and illustrated by Ian Churchill.
