"Katherine Knolls", voiced by Lisa Picotte

For some time, Jade lived a secret life as an auto-vigilante. Her family never knew her driving skills were also put to the test outside the racetrack. Probably for their own good. Her looks can be deceiving, as many find out who cross her path. One day, while leaving a race track in Texas, she spots a large group of auto-villains. The local police does not interfere, as if they know something she does not. She goes after them and stumbles upon something big. The game begins with her brother Groove taking up her cause, hitting the road in her Piranha. Jade's handle was "Vixen." She has a younger sister named Skye.
