Whirl is a 14-years-old Cybertronian police trainee who transforms into a blue and light gray police helicopter. Cybertronians are a race of autonomous robotic organisms from the distant planet of Cybertron. Cybertronians can age slowly, and have the ability to scan vehicles and transform into said vehicles. Cybertronians who transform into aerial vehicles such as Whirl are known as Flight-Bots or Aerialbots. Whirl aspires to be a Rescue Bot police officer like Chase, though while her senior has a no-nonsense approach, Whirl is all optimism and heavily into Earth culture like fellow Aerialbot Blades. Her enthusiasm for the work can be overwhelming, and her sense of judgement may lead to some simply ridiculous theories and quotes, giving her fellow recruits pause; more often than not she's proven right, though it may take some time for her friends to follow her advice. Whirl was among those selected to be a recruit at the Rescue Bot Training Center on Earth. Her other teammates includes the swaggerer Hotshot, the shy engineer Hoist, the hotheaded Wedge, and the callous medic Medix.
