"Batgirl" Yvonne Craig, a true television pioneer who paved the way for female superheroes on her Batcycle, has succumbed to breast cancer. She was 78.
Her family announced her passing on the star's website.
"She had been in chemo almost continuously for the past two plus years since being diagnosed and that had weakened her immune system as well as her body," the family statement said.

"This didn’t dampen her sense of humor or her spirit, she intended to fight and win this battle. In the end, her mind still wanted to fight but her body had given up."
Craig joined Burt Ward (Robin) and Adam West (Batman) in the third and final season of the Batman television series in 1967.
She played Barbara Gordon, the sharp-as-a-tack daughter of Commissioner Gordon who joined the campy dynamic duo to battle the Penguin and other Gotham City villains.
She even had her own, super-funky them (see video above) music. Craig's batgirl tooled around Gotham's streets on a lace-frilled purple Batcycle.
A secret wall that spun around in her very feminine bedroom -- there was no cave -- hid her vanity and Batgirl outfit.

Craig also had one of the most memorable female appearances on Star Trek, playing th green-skinned seductive Orion slave girl, Marta.
A trained dancer, the athletic Craig did most of her own stunts.
Her family said that Craig did not want her loved ones or fans to "waste a moment of their time in mourning for her loss in sadness."
Instead, she wanted them to "celebrate the awesome life she had been fortunate enough to live. She felt that she lived a wonderful life and was blessed in many ways."
"I hear from women that I was their role model," she once told CNN.
"'When I was a little girl, I realized that girls could kick butt just like guys."
