Lucy Mann is a girl from the Ben 10 series. For more info, click here.
Lucy is a very upbeat and mischievous girl, who loves playing pranks on people, as she especially enjoys teasing her cousin Gwen. She's very silly, but is also apparently quite competent, seeing as how she managed to get through Plumbers' Training Academy in a relatively short amount of time.
In the original series, Lucy has long blonde hair with blue eyes. She is shown wearing a black sleeveless shirt with a star on it, along with a red skirt. She also has two distinct whisker marks on her face.
In Omniverse, 11 year old Lucy's skin is more pink, the whisker like marks on her face are gone, with freckles taking their place. Her eyes have changed color, becoming purple.
16 year old Lucy wears a sleeved dress, with a red collar, a star on the chest area, socks that go over her knees and wears red lipstick.
Lucy's 10 year old Sludgepuppy form was not shown.
Lucy has two different Sludgepuppy forms, her more natural one, lacking legs with larger head tendrils and less human facial features, and her humanoid form, which is smaller, has legs, and a more human like face with mud flowing around her head, resembling hair.
- Lucy bears a resemblance with a Wonder Girl.
- She is the first ever Sludgepuppy to become a Plumber.
- So far, she appears to be the youngest Sludgepuppy seen in the Ben 10 series.
- According to Ben, Lucy is Gwen and Ben's "Grandpa Max's brother's son's wife's mother's sister's daughter", or simply, their cousin.
- Lucy resembles the female form of Naruto (from the anime of the same name) when he uses a disguise technique, making it the second such episode to feature a background character, that resembles a Naruto character (the first was "Merry Christmas"). Lucy also resembles Kitten (who is also voiced by Tara Strong) from Teen Titans in Date with Destiny.
