|Introduced in||"The Creeps"|
|Latest appearance||"King Worm"|
The Ghost Lady appears in "The Creeps" when Finn thinks he's the last one "alive," and hides in a room in the Castle. Suddenly the Ghost Lady appears through the wall, and she gazes at Finn while her hair slowly fills the room. Finn then breaks through the wall to the next room to escape (which had a chair and floorboarding that also attacked him). He later finds out the party was just a prank by Jake , but when he mentions the encounter Jake is puzzled, and says that Finn must have imagined it. Later while leaving the castle he decides to forget the experience by putting it "in the vault."
She made a reappearance in "King Worm" when Finn unleashed his subconscious fears to escape his dream. This reveals that although Finn put the memory of her "in the vault" he is still subconsciously afraid of the specter.
AppearanceEditThe Ghost Lady has light greyish-blue skin with scale-like lumps and long, green seaweed-like hair. Her neck is unusually long. Her scales are light blue, her irises are black, and her pupils shine red. Interestingly, her appearance differs from the most of the other Ghosts in the series, who are all less colorful and more smoothly shaped. Her design is also similar to a Japanese style ghost.
In the castle, just before the top floor, there is a picture of a blue-ish green woman with long orange hair hugging a mutant bull. The woman in the picture bears a resemblance to Ghost Lady and could have very well been her when she was alive.
The Ghost Lady phased through a wall, which was preceded by a ripple effect on the space and a humming sound. Her green hair grew to fill the library that Finn was hiding in, as if trying to reach him. She was also able to tear holes through the floorboarding, move a chair, and summon crows from a painting while either offscreen or invisible (or there might have been other ghosts in the house that were responsible).
