Madeline is a former Animalian politician and former member of the Animalian national Socialist Union.
She is an anthropomorphic Alaskan Malamute and unlike Charlotte and Indira whilst her dog breed is muscular she has a rather muscular physique unlike Indira who's dog breed is muscular but her body is feminine and Charlotte who is only muscular because of her suit. Like the Belgian vixens Beatrix and Astrid Madeline wears more ancient clothing but does not wear armor. In this case her clothing is white Ancient Chinese style boots, black knee length trousers and a grey Ancient Chinese style jacket with a green belt and green edges where it is fastened like an ancient Chinese warrior, less extreme though than a Samurai.
If there's one thing that Madeline loves then it's power but she does not crave it as much as Shannon does instead accepting her role in the Animalian Union but nonetheless she does enjoy power and also abuses her position of power instead exploiting prisoners for her own ends. She can be very social darwinistic often seeing sympathetic allies as being "weak" as well as fiercely misogynistic also wanting to capture the Romanian dogs Ioana and Maria but mainly many female dogs in the Animalian Patriotic Front. However she also dreams of taking the Junta babies Josefina and Santiago into somebody else's care, Josefina into her care and Santiago into somebody else's, who's care she intends to put Santiago into is not entirely known but it is assumed that they are in the Animalian Union or the Junta.
Her power hungry personality also is boosted by many who enjoy her personality namely Mechanikat, Oswald, Helen and her boss Irma, fortunately she knows most power goals are too unrealistic but nonetheless like Shannon the power she wanted goes to her head and destroys her. Usually she is un-accepting of defeat but the end of the Junta years is an exception. But despite her power hungry personality Madeline does respect her allies and eventually her old enemies as well as the members of the Fox Junta and their allies.
