The Ultimate Vampire Resource and Directory

Cybergirl is a super heroine living under the secret identity of ordinary teenage girl Ashley Campbell. In reality, she is a "Cyber Replicate" from a distant planet.
Her powers include super-human strength, super-human speed, and the ability to interface directly with electronic devices and computers. She is also able to physically change her appearance between that of the blue-haired, ethereal-looking Cybergirl and the less conspicuous, mousy-haired Ashley, and can alter her clothing at will.
