Another character created by the Batman animated series, Renne Montoya was the only female cop to be named during the show. And even helped out Batman on numerous occassions. In one instance, she caught Poison Ivy and Harley Quinn by herself.
She was later brought into the comics as a member of the GCPD once more. But later on, she became the second person to take on the identity of The Question. She was also a character who came out as gay, and had a long relationship with Batwoman Kate Kane.
