Lucy Mann

Lucy Mann is a character in the animated series "Ben 10," Ben and Gwen's cousin, who works as a plumber for the Cosmos (the space police that catches alien criminals). She is an alien from the Lenopan race. She can transform into various other living beings (such as Ben Tennyson and Kevin Levin). Lucy is a cheerful and mischievous girl who loves to play pranks on people. She is quite competent, considering how she managed to graduate from the Plumbing Academy in a relatively short period of time. Lucy is also a creative person; she writes poetry well, sculpts, and paints.

Appearance: Lucy has long blonde hair, pinkish-purple eyes, and freckles. She wears a black dress with a red collar, a star on the chest, white knee-length socks, red shoes, and red lipstick. Her hair is pulled back into a ponytail with a red ribbon. Lucy has two Lenopan forms: a natural form, legless, with larger antennae on her head and less human-like features, and a smaller humanoid form, with legs and a more human-like face. She can also take any form she wishes.

Underneath a regular old plumbing store is a giant green base where alien criminals are kept, and this is where the headquarters of the space plumbers (that's the space police) is located.
