Like Sage and Nova, Dementia has the same hairstyle, except it's all messy and she prefers the colour blue. Dementia also wears a spiked collar with a tag that says "666" on it, as well as an animal tag on her ear, and a blue, spandex straitjacket.
Dementia 13 was dropped off in an asylum called "Downpours Asylum for the Criminally Insane" for a vast long time as a newborn. Believing that the doctors and inmates were her "family" she grew fond of them all. She was always in her best behavior (until 6 O'Clock) and enjoys electroshock therapy. The doctors were fascinated with Dementia 13 that they proceeded to experiment harsh tactics on her (In her own will). As she was raised in the asylum, she became psychotic, unstable and mentally deranged.
