Charlene Davidson, better known as Charley, is a female mechanic, and the best friend of the Biker Mice on Earth. The Mice are always backed up by Charley, an auburn haired, green-eyed beautiful girl mechanic, who owns the Last Chance Garage in Chicago. She is a headstrong woman and is always ready to go into battle, though the Biker Mice try to keep her out of dangerous situations, never because they think she is incapable or weak, but because they could not bear anything bad happening to her. Aside from being the target of Vinnie's affection (which she playfully blows off) and being close with Modo, she is also responsible for repairs and upgrades to the Mice's bikes, is a high-tech genius in her own right, and is as skilled a biker as the Mice. Her name is an obvious pun on Harley Davidson.
Rock and Roll Music[]
In the songfic, she, the Biker Mice and Ikran's younger self-narrator were hanging out in her garage as Vinnie was jamming to the Beach Boys' hit of the same name after she'd been struggling with critical thinking questions in her grammar reading class; Charley and Throttle wanted to teach her how to use her mind to solve problems even when on the fly.
The Myth of Mars[]
She was mentioned subtly as she took in the Biker Mice in her repair shop in Chicago. After she moved to Mars, there were some evidence of leftover relics from the Biker Mice such as VHS tapes, tools, motorbikes, etc. Thanks to her it was proof that life existed on the Red Planet! Thus, humanity evolved and migrated there! And the Mice had become extinct with the other races.
