The Criss Cross Conspiracy!

A woman named Katrina wanted to be crime fighter like Batman so she donned her own costume and joined him when he battled the Riddler. She catches the Riddler but in an act of spite he removes her mask revealing her true identity. A few years later, she’s bitter and wants to get back at the Riddler so she goes to Felix Faust and asks him to give her a spell. She then calls Batman and he goes to her place and she enacts the spell which allows her to swap bodies with Batman. She then goes out to find the Riddler while Batman trapped in Kristina’s body tries to find a way out.
