Kestrel is a peregrine falcon and the reigning champion of an underground aerial racing circuit where anthro flyers compete at breakneck speeds through urban obstacle courses. He is the fastest flyer anyone has ever seen, capable of reaching speeds over two hundred miles per hour in a dive. He is laser-focused, hypercompetitive, and runs on pure adrenaline. Off the course he is restless and impatient, a speedster trapped in a world that moves too slowly.
