Maureen Corley, known as Mo by her acquaintances, is the illegitimate and only daughter of the CEO of Corley Motors, Malcolm Corley. She was raised away from her father and mother. A mechanical genius, she rebuilt her first carburetor at age of four. Together Malcolm and Mo built a vintage hardtail one summer, but eventually left her alone because of Adrian Ripburger's suggestion. Malcolm still let her secretly enter the Corley Motors factory to help her father with bike designs. He used to call her the "Diapered Dynamo".
