Demencia (or Dementia[5]) is one of the main characters of the show Villainous.

Personality
Demencia's shown to be a very energetic, rebellious, mischievous, flirtatious, and scatterbrained girl. She acts without thinking first often, which it causes many of the group's problems. Also she can be very difficult and go directly against orders or rules. Demencia's madly in love with Black Hat, much to his annoyance. 5.0.5.'s usually the victim of her pranks; it's implied that this's because Demencia sees 5.0.5. as weak and timid.

Demencia has intense cannibalistic tendencies. This was seen three times in the pilot episode alone:

1.The superhero that was lowered into her pit for breakfast, during her introduction.
2.A cheerleader she tried to eat while waiting for Sunblast to show.
3.Catching and swallowing an escaped shrunken Sunblast with her tongue like a frog.

Appearance
Demencia's outfit consists of a navy blue vest attached to a hood which it resembles a reptile (possibly a dragon), mismatched sneakers (her left shoe's red, while the right shoe was teal until "The Lost Cases of Rhyboflavin"—ever since then, she's lost it, and she currently wears a black one[6]), a tracking device[7] on her ankle, and long, striped stockings, which the one on her right leg's torn. She wears a black skirt and she has a black fingerless glove on her right hand. Although she's usually covered by her hoodie, a spiked choker's fastened around her neck, similar to the bracelet she wears on her left wrist. Although it's not pictured in the show due to its art style, Demencia wears black nail polish.

She has a long, distinctive neon-green ponytail that comes out from behind her hood, and her bangs are dyed pink. Her right eye's an odd eye with yellow iris, while her left eye has a slit pupil with no visible iris. She has two black bar-shaped earrings in her right ear, and somehow she managed to take a bite out of her own left ear. When she's crawling on all-fours, her hoodie, her bangs, and her hair combine to form a giant lizard, with the bangs forming the tongue, and the rest of her hair forming the body and tail.
