Cindy is the sister of Jimmy and an aspiring race car driver.
Physical appearance[]
Cindy is a young girl with blonde hair held in two pigtails. She wears an orange and black jumpsuit worn by racers with a black zipper and a blue collar. She also wears a pair of black sneakers with white soles.
Personality[]
Just like her brother, Cindy is confident about her racing abilities, but she is more boastful and prideful than her brother. Usually, her brother would stop her from boasting with a glare, and she would humbly credit her father for teaching her about racing. Nevertheless, she shares the same spite against racing officials with her brother, feeling disrespected and underestimated due to her age. Because of this, they turned to crime to fulfill their ambitions of racing, using dishonest means such as controlling their car remotely and sabotaging other racers.

What's New, Scooby-Doo?[]
Season three[]
Cindy and her brother, Jimmy, attempted to enter the Gainesville 500, but were deemed too young to compete. Angry at the race officials, they created a plot to win the race by remote-controlling a race car, placing a crash test dummy disguised as their father in the driver's seat. While Jimmy controlled the car, Cindy controlled a second vehicle, a monster truck operated by a skeleton driver. The Skeleton Driver would sabotage competing racers by attacking them on the racetrack, often destroying their cars. They controlled both vehicles remotely from a radio tower, where the signal would be strong enough to reach the entire track.

Cindy unmasked.
Mystery Inc. first met Jimmy and Cindy in the trailer park near the track. Mystery Inc. spotted their "father" inside their trailer, but they noted that he did not respond to their calls (as he was really a dummy). Jimmy and Cindy then planted a device in Fred's race car, allowing them to remote-control the car. In the race, Jimmy and Cindy hijacked Fred's car, forcing it to crash into a billboard and swerve uncontrollably. However, the other members of Mystery Inc. rescued him, as Shaggy entered the vehicle, found the device, and disabled it. Velma then modified the device to block radio signals, stopping both the Skeleton Driver and Jimmy's race car. Mystery Inc. spotted Jimmy and Cindy atop the radio tower and exposed them for their crimes.
