She is an anthropomorphic Leopard and of the guards at Trebdanek is another distinguishable. She wears a white blouse, a dark green skirt, a dark green jacket, black leather gloves black boots and a black belt across her waist but her belt also has a gun holster. Another thing that distinguishes Kerryn is that she often wears a brown cloak and on occasion this cloak is hooded and most of the time she often wears the cloak on night duty and also often sneaks out of her barracks. Most of the time Kerryn carries a riding crop in one hand and a pistol in the other but is very rarely seen carrying both and instead either carries a riding crop with her pistol in it's holster or her pistol with her riding crop tucked into her belt.
Of the way most prisoners are tortured at Trebdanek Kerryn's is the most fearsome because though she does beat victims she also takes someone to be executed, takes out her magazine from her pistol and shoots the victim in the back of the head which is a mock execution. Sometimes she lets the victim live but after she sends them off she re-loads and sometimes shoots her victim as they are leaving her in the back of the head or in the chest before shooting them again. Either way any victims of Kerryn always end up dead.
Beneath her murderous personality Kerryn seems to be a sympathetic character because at night she often sneaks out and takes small children out of their camp and to her barrack but in actuality she is none of the sort because eventually she tires of them and sends them to their deaths.
Kerryn is one of many guards who hears Mechanikat's message but decides not to kill herself and instead flees with Hannah. Or tries because the group is eventually captured by the Animalian Patriotic Front. She is later tried at the Anthro Junta Trials and sentenced to three years in prison. Today she lives in Animalia.
