Demencia from Villainous is, in spite of what her excitable and outgoing demeanor might insinuate, an incredibly competent super-villain who works as Black Hat's main hitman for the organization. She is cheerful, energetic mischievous. She is romantically obsessed with Black Hat, tends to pick on Dr. Flug and 505, though she does have some care for them. She is able to swallow others whole and digest her prey, something she might do given her cannibalistic tendencies.
