She is an anthropomorphic Snow Leopard who also wears different clothing to other members of Trebdanek. Melissa wears a white blouse, a black knee length skirt and standard colored tights but like some other guards she goes barefoot.
Like her friend Melanie Melissa likes to show her body off. Most of the time she merely walks round Trebdanek waiting for someone to look at her at her and if anyone does she has them killed. Also like Melanie she often likes to wear little clothing as most of the time Melissa's clothing merely consists of a blouse and a pair of tights and also like Melanie often likes to walk around Trebdanek bare chested. Melissa also likes to exploit female prisoners often in the most humiliating ways possible.
After the fall of the Junta Melissa tries to flee with Hannah and though others have pressured her to leave she refuses every single time and after the Animalian Patriotic Front advance on Trebdanek she is arrested by the A.P.F. At her trial Melissa is found guilty of theft, exploitation of prisoners and acts of sadism and sentenced to 20 years in prison. Today she resides in Animalia.
