Collins, and Blair Montgomery's supposed fiance. She first appears in Serial 11 "The Planet of Genetic Misadventure" under a hypnotic trance, walking around Halloween's palace talking about how much she is in love with Blair. Later on it becomes clear that she is being used as a pawn by her mother as means for Halloween to gain untold amounts of wealth, and thus it falls on the Amazing Detectives Agency members Spike Malone, Richie Watson, and Gene Taylor to save her from a terrible fate. Being a member of the Ruling Family of Halloween she has her own magical powers, though they are nowhere near the level needed to contest her mother or Blair's magic.
Like the other members of the Collins family, her last name is a reference to the Collins Family from Dark Shadows.
