Fat Chicken is a vanship pilot from Norkia. She is a member of the Vanship Union and an active racer. She is one of Claus and Lavie's largest racing competitors; Lavie has given her the nickname "Piggy Bird" due to her weight. Fat Chicken competes in the 75th Norkia Cup Race, starting in the second position, but is forced to withdraw after experiencing difficulty navigating one of the narrower sections of the course. Fat Chicken later participates in the rebellion against the Guild as a member of the Alliance, piloting her vanship in a torpedo run against a fleet of Guild Battle Ships.
