Biography
Cynthia appeared in "Goku's Ordeal". She was assigned as Piccolo's driving instructor. She was beautiful and stylish, but under this exterior she was really a speed demon in that her personality completely changed the moment she took the wheel. Even her speech style changed, becoming extremely rude. She coaxed Piccolo when he raced with Goku. The complete opposite was seen with Goku's driving instructor, Yuzukar.
