Lilith Clawthorne is a major character in The Owl House.

Lilith is the older sister of Eda Clawthorne and the disgraced former leader and lead historical scholar of the Emperor's Coven. She was living with her parents, trying to make up for lost time and to develop a cure for her and her sister's curse, along with getting a job in the interim until the Day of Unity, where she was captured by the Collector.

Lilith is a tall, slender, middle-aged woman in her mid-to-late 40s (two years older than Eda). She has ivory skin, pointed ears, black lipstick, and mint green eyes. She also has dark claw-like nails. In her debut, Lilith has long straight hair which she dyed a dark-navy color. Her natural hair is fluffy and orangish-red, as shown during her childhood and the epilogue. After splitting the curse between herself and Eda in "Young Blood, Old Souls", Lilith's right eye becomes gray, and she obtains a gray streak on the right side of her hair. In the second season, Lilith's skin has gotten paler, and she has prominent wrinkles under her eyes. In "Follies at the Coven Day Parade", the lower portion of her hair becomes fluffy and curly. In "For the Future", her hair has been cut short, exposing her natural red hair. In the epilogue to "Watching and Dreaming", her hair is further grown out, maintaining its curls.

As the Raven Beast, she resembles almost all of Eda's characteristics in her cursed form, but with black hair, large, crooked fangs, a longer neck, black claws, her ears having small ridges with no hair growing out from them and is much larger than the Owl Beast.

As a harpy, her form is exactly like Eda's, but with her orange hair, mint green eyes with black sclerae, a black kite-shaped gem, and raven-like wings. She also seems to be able to change into this form at will, as well.
