Overview
Sirena Von Boo is a 2014-introduced hybrid of a mermaid and a ghost, making her a student at Monster High with unique abilities.
Sirena Von Boo is a 2014-introduced and all-around character. She is a hybrid, the child of a mermaid and a ghost, which makes her a mermaid ghost and a student at Monster High. Like her longtime hybrid friends—Avea Trotter, Bonita Femur, and Neighthan Rot—, Sirena has a history of going from school to school because she fit in nowhere. As a result, she is acutely aware of her double heritage that is making life so difficult for her. On the other hand, she would not trade her omni-mobility for anything in the world. She can travel underwater, float in the air, and pass through anything, and the possibilities this presents her with are endless.

Character
Sirena Von Boo features stark white skin, ultramarine hair with lavender streaks, and a tail that shifts colors, reflecting her hybrid nature.
Sirena Von Boo has stark white skin that flows over into the scales of a tail that changes from silver to blue to black at the bottom. Her long, ultramarine hair has lavender streaks through it, and part of it is coiled and twisted; the rest flows down past her waist in side-curls. She has blue eyes, and from the elbow down, her skin fades into black. She wears a golden or green one-shoulder top and has several long, black strands of fabric tied around her wrists.
Sirena is sometimes described as an "air fin" because she loves to daydream and follow her imagination. She has a go-with-the-flow attitude and doesn't like to be pinned down. She loves hunting for treasure in the sea and frequenting antique shops on land. This curiosity about the unknown has translated into a love of archeology; she is highly interested in the world around her. She may be easily distracted, but she has a kind soul and a good heart.
- Floating: As a ghost, Sirena can float, which comes in handy considering she has a fishtail and wouldn't be able to move outside of water.
- Permeation: Sirena can phase through solids and liquids easily, which gives her the ability to swim despite not being fully mermaid, but going through solids is from being a ghost.
- Immortality: As she is half ghost, it's implied that she is immortal like other ghosts.
- Swimming: Sirena is a particularly great swimmer. She has created a great bond with Lagoona Blue because of their love for swimming.
- Diving: Sirena is a really talented diver. As shown in Freaky Fusion, Lagoona was very impressed that Sirena pulled off a quadruple reverse somersault without splashing.
Relationships
Sirena's parents are a ghost father and mermaid mother, and she shares close friendships with fellow hybrids and other students.
Sirena's father is a ghost, and her mother is a mermaid, and the two met underwater in a sunken ship. Their relationship with Sirena is rather complicated as, in fear of getting one of her two scaritages over the other, they hide a lot of things from her, such as the existence of the Ghost World or the celebrations each of the sides has.
Sirena's best friends with her fellow hybrids, Avea Trotter, Neighthan Rot, and Bonita Femur. Though she's also seen interacting with Lagoona Blue in the webisodes "Happy Howlidays" and "Looks Gil-ty" of which she admires Lagoona's diving skills and follows her as she tries and figures out whether Lorna McNessie and Gil Gillington are dating. Sirena is also friends with Spectra Vondergeist, as shown in "Happy Howlidays" and they bonded over their ghost scaritage in Sirena's diary.
