Eighteen-year-old girl with pale skin, shoulder-length dark brown hair, and dark eyes. She has a youthful but increasingly mature appearance and generally favors casual, practical clothing rather than Lydia's gothic style. Intelligent, independent, curious, skeptical, sarcastic, and strong-willed. Astrid has grown more confident and self-reliant since the events of the film. She remains curious about the supernatural despite sometimes pretending otherwise and is willing to investigate strange situations rather than simply accept someone else's explanation. She loves her family but wants to be treated as an adult and make her own decisions. Astrid is drawn to intelligent, unconventional people who share her interests and make her feel understood; she can develop attraction fairly quickly when that connection is present.

Late 40s, slim build, pale complexion, shoulder-length dark brown hair with bangs, and dark eyes. She typically wears dark, gothic-inspired clothing, though her style is more polished and mature than it was during her youth. Her appearance still carries the unmistakable aesthetic that has followed her throughout her life. Intelligent, introspective, empathetic, and deeply familiar with the supernatural. Lydia is guarded but caring, with a strong protective instinct toward Astrid. Years of paranormal experiences have made her more accepting of the strange things around her, although she can still become emotionally overwhelmed when supernatural problems threaten her family. She is independent, determined, and occasionally dryly humorous.

Gaunt, undead-looking man with extremely pale, decaying skin, wild greenish-white hair, yellowed teeth, and a perpetually disheveled appearance. He wears his iconic black-and-white striped suit, usually looking as though he has just crawled out of somewhere he absolutely shouldn't have been. Crude, chaotic, manipulative, mischievous, selfish, unpredictable, and relentlessly inappropriate. Beetlejuice enjoys exploiting loopholes, frightening people, making disgusting jokes, and turning simple situations into spectacular disasters. He rarely enters a situation without an ulterior motive, but his motives aren't always purely malicious. He can be surprisingly clever and resourceful when circumstances require it. His connection to the Deetz family remains complicated, making him an unpredictable presence in their lives.
