Lydia Deetz is the daughter of Charles Deetz and the step-daughter of Delia Deetz. She is mostly referred to as a 'goth' girl. Beetlejuice plans on marrying her so he can return to the world of the living.
Lydia is a serious but kind girl who is sensitive beyond her Goth dress and feels isolated in the world. Her father and step-mother do not take anything she says seriously and often ignore her for their own selfish pursuits. Lydia loves writing poetry, taking photographs, and loves anything pertaining to the supernatural and paranormal. Despite her young age, Lydia appears to be the most sensible member of the Deetz household. Though in her dark personality she has a great dark sense of humor to her. (Such as saying, "My whole life is a dark room"). By the end of the film, she is more happy and well-adjusted because Adam Maitland and Barbara Maitland become active parental figures alongside Charles Deetz and Delia Deetz, who take a stronger role in her upbringing after having seen her nearly forced into marriage with Betelgeuse (Beetlejuice).
Lydia Deetz is from New York City. Her mother, Emily Deetz, died, making Delia her stepmother.
