Lily is the matriarch of the Munster family. She is a beautiful and slender woman who appears to be in her middle age years, although she is actually hundreds of years old. Later incarnations of the character, played by different actresses, would change her skin from green to pale white. Lily usually dresses in an ankle-length pale pink gown that appears faded and old, and she sometimes also wears a scarf. Her necklace features a bat-shaped medallion. When away from the Munster house, she often wears a long silver cape with a hood, which in reality is a casket liner. In the episode "Munsters Masquerade", Lily demonstrates the ability to float in the air while dancing. She is very close with her niece, Marilyn. She has a werewolf for a brother, who appears in one episode, and a sister who is mentioned a few times who is Marilyn's mother. Lily is the voice of reason in the Munster household, often relied upon to set problems right, and typically mediates when Herman and Grandpa squabble.
