Psych!

”

Lucy Mann is a Lenopan Plumber and Camille's cousin. She was one of the Lenopans not to be involved in the sabotage of Camille's wedding.

Appearance

Human Form

In the original series, Lucy had long blonde hair with blue eyes. She wore a black sleeveless shirt with a star on it, along with a red skirt. She also had two distinct whisker marks on either side of her face.

When performing as the flower girl, Lucy wore a green dress with a pink rose in her hair.

In the Omniverse flashbacks, 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 pinkish purple. She also wears a red hairband.

As a teenager, Lucy wears a black sleeved dress with a red collar, a star on the chest area, white socks that go over her knees, red shoes and red lipstick. She wears her hair in a ponytail.

In Mud Is Thicker Than Water, Young Lucy wore Gwen's favorite shirt over her black sleeveless shirt.

Lenopan Form

Lucy has two different Lenopan 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.

Her young humanoid Lenopan form looks exactly like her teen self, except she's smaller.

Personality

Lucy is a very upbeat, mischievous and happy-go-lucky girl, who loves playing pranks on people. Her catchphrase is "Psyche!" She especially enjoys teasing her cousin Gwen, much to her other cousin Ben's amusement.

Lucy is quite competent, as she managed to get through Plumbers' Training Academy in a relatively short amount of time.

Lucy likes pottery, and anything having to do with mud or clay.

History

Ben 10

Lucy first appeared in Big Fat Alien Wedding, where she comes to Camille's wedding to perform as the flower girl. She is first seen at the wedding rehearsal where she talks about how thrilled she is about being the flower girl and dancing with Ben although he didn't share her enthusiasm. At the wedding she is forced to flee with most of the guests when Mr. and Mrs. Mann and their bodyguard attack but later returns with Camille's bridesmaids once the battle is over to accompany her cousin and Joel as they finally get married and dances with Ben, although he ends up tripping with mud since she had partially turned back into her Lenopan form, most likely because Ben, still not knowing how to dance properly, kept stepping on her shoes so she had to turn her feet back into mud to avoid this, causing Ben to trip and Gwen to take a picture of the incident while Lucy seemed very amused about the whole thing.

Five Years Prior to Omniverse

In Mud Is Thicker Than Water, Lucy is in Gwen’s room, she reveals to her that she’s staying at her house for a few months. Gwen gets mad when she sees Lucy wearing her favorite shirt and using her hairbrush. Lucy asks Gwen what is Kevin like, and she responds saying he’s the worst since he’s so tough and bad. Lucy believes Gwen likes Kevin and starts to tease her, but she rejects that theory.

In From Hedorium to Eternity Lucy is at Ben’s House along with Ben and Gwen. Lucy along with Ben, Gwen, Cooper, and Jonesy team up with Kevin underground. Lucy helps to defeat Zy’skarr. Lucy teases Gwen about liking Kevin which causes Gwen to chase her.

Omniverse

Lucy returns in Mud Is Thicker Than Water, where she is brought in by the Plumbers to pose as Liam to find out who was the mole in Plumber HQ. Gwen is convinced that Lucy herself is the mole (due to her feelings towards Lucy from when they were kids), but Ben defends her asking Gwen if Lucy is truly capable of such actions and that "Cousin Lucy is awesome". The Plumber's attempt to bait Psyphon's Gang into coming out into the open by transporting a fake Annihilargh (the real one was revealed to have been rebuilt by Blukic and Driba). Gwen truly believes that Lucy was the spy and that she was behind the sabotage at the base, until Lucy reveals herself to be the spy in Psyphon's Gang (while revealing her Lenopan form in the process).

Working together, Ben (as Crashhopper), Gwen (in her Anodite form), and Lucy (in her humanoid Lenopan form) battle Psyphon and his gang. Lucy impersonated Vilgax and terrified Psyphon before tripping him with some of her sludge and leaving Crashopper to defeat him. Gwen then apologizes for suspecting that Lucy was the traitor, Lucy forgives on the basis that they are family and promises to return the favor when she is promoted to commanding officer. Gwen laughs at the prospect of this, but quickly becomes serious and worried when she realizes that Lucy could possibly not be joking. Lucy walks off and laughs while Gwen nervously chases after her.

Lucy is referenced in Collect This when Ben tells Deefus Veeblepister that he has "a few Lenopan cousins."

Trivia

• Lucy is the first ever Lenopan to be a Plumber.
• No matter how big or small she makes herself, Lucy will still retain her normal Lenopan strength.
• Lucy's eyes went from being blue to purple because Matt Wayne modeled her human look after Elizabeth Taylor, whose eyes were either blue or violet, depending on the light.
• Lucy bears a striking resemblance to a younger Cassie Sandsmark/Wonder Girl from DC Comics (specifically her Young Justice incarnation) due to her blonde hair and her shirt, which was one of Cassie's first costumes.
• The whisker marks on her face give Lucy a striking resemblance to the female illusion form of Naruto, from the popular anime series of the same name.
