Spooky

Spooky is a cartoon ghost of a 12-year-old girl.
Personality: Spooky loves silly pranks and sudden jump scares. She enjoys dark humor. She's sarcastic, capricious, hypocritical, and has a love of murder. Spooky also respects people who find her even the slightest bit scary.
Appearance: Spooky has the appearance of a cute, cartoonish, floating ghost. She has round, simplified facial features, pale skin, black, cartoonish oval-shaped eyes (which sometimes have white highlights), and a black, cartoonish, toothless mouth. Spooky has long, blue-gray hair with bangs. Spooky typically lacks legs (but can create them when she needs to).
Clothing: Spooky wears only a pale blue dress with short sleeves and a torn hem.
Traits: When Spooky blushes, her cheeks glow a cool bluish color.

Immortality and Intangibility - Spooky is like a ghost, immune to physical damage, disease, and old age. Spooky can float freely in the air and pass through walls.

Becoming Tangible - Spooky can become tangible at will (but she is also immortal and does not feel pain) to interact with people and objects.

Space Distortion - Spooky can change the structure of rooms, generate new corridors, and lock doors with a snap of her fingers.

Teleportation - Spooky can instantly teleport to any point in his mansion, suddenly appearing in front of the player at checkpoints.
Mind Control and Illusions: She is able to inflict hallucinations on her victims and suppress their will, causing them to go mad with fear even before they encounter the monsters.

Stamina Manipulation (Running Block) - Spooky can cast a curse that completely disables a person's ability to run for several minutes.

Materialization of Objects - Spooky is able to create objects out of nothing.

Physical Mergence with the Mansion (Vessel Binding) – Most ghosts are bound to dolls or small objects, but Spooky was able to bind her spirit to the entire enormous mansion. This gives her the status of an absolute god within these walls.

Ghost Telekinesis - Spooky is able to move heavy objects through the air.

Invisibility and Surveillance - Spooky can become completely invisible, tracking a person's movements through the walls of rooms, remaining undetected until she decides to show herself.

Technology Interaction - Spooky can interact with technology.

Possession of people - Spooky can also possess people and control them as he wishes.

In life, Spooky was an ordinary girl who loved Halloween and adored scaring people. However, because of her cute appearance, no one took her seriously.
One Halloween, Spooky decided to pull a major prank on her father (or, according to another version, her neighbor), disguising herself and using explosive bags/firecrackers. Her father, a war veteran with severe post-traumatic stress disorder (PTSD), mistook the sounds of the explosions for an attack and, in a panic, shot and killed his own daughter.
Her parents tried to revive her in the hospital, but in the end she became attached to this mansion.
