*Cynthia (シンシア, Shinshia) is one of the teachers at the hovercar training facility in which Goku and Piccolo attended.

In the anime, she appears on the surface to be friendly and nice. However, as a driver her personality switches, becoming rash and wild in her speech and behaves in a manner unbecoming of a driving instructor, as she drives aggressively and recklessly, even encouraging Piccolo to race with Goku.

In Kakarot, her personality however is similar to Yuzukar and behaves as one would expect a driving instructor to, reprimanding Piccolo if he drives recklessly.*
