Bunbee is part of the evil organization Nightmare, the main villains in Pretty Cure 5. Throughout the series they try to steal the "Dream Collet", a powerful magical artifact held by Pretty Cure, in order to destroy the world. Bunbee is introduced as one of the higher-ups in the organization, but soon serves - because of his great misfortune, constant failures and sometimes stupid behavior - as a comic-relief. His appearances are often quite random (bursting into a laughing group of girls by laughing like a little girl). Bunbee is the only villain to survive both Pretty Cure 5 Seasons.
