However, according to our friends at the BBC, she's back, with a new look - and a new outlook:
Comic book heroine Batwoman is to make a comeback as a "lipstick lesbian" who moonlights as a crime fighter, a DC Comics spokesman has confirmed.
Batwoman - real name Kathy Kane - will appear in "52," a year-long DC Comics publication that began this month. In her latest incarnation, she is a rich socialite who has a romantic history with another "52" character, ex-police detective Renee Montoya.
[Other "52" characters] include Mexican teenager Blue Beetle - who replaces the character's previous white incarnation - and the Great Ten, a government-sponsored team of Chinese superheroes.
Regular characters Firestorm and The Atom, meanwhile, have been reinvented as black and Asian heroes respectively.
You go, girl.
