Dementia is a genetic whose power consists of manipulating (through telepathy) the centre of fear in the brain of her opponent (or any man and woman for that matter). This manipulation leads to manifestation of the nightmares to the person affected.
While straneous to her, it's possible for her to cause heart failiure due to adrenaline flow in the body caused by the fear, or cause a rapture of a blood vessel in the brain of her opponent.
Although she has other "assets" this one is a "hard candy". Hard enough to make you poop your pants. A sadist, psihotic and a sciopath. Hope you like her. All rights reserved by the artist.
