Lucy Mann

Lucy Mann's History

Ben 10

Lucy first appeared in Big Fat Alien Wedding, where she came to Camille's wedding to perform as the flower girl. She was first seen at the wedding rehearsal where she talked about how thrilled she was about being the flower girl and dancing with Ben, although he didn't share her enthusiasm. At the wedding, she was forced to flee with most of the guests when Mr. and Mrs. Mann and their bodyguard attacked, but later returned with Camille's bridesmaids once the battle was over to accompany her cousin and Joel as they finally got married and danced with Ben. He ended up tripping with mud since she had partially turned back into her Lenopan form. Gwen took 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 revealed to Gwen that she would be staying at her house for a few months. Gwen got mad when she saw Lucy wearing her favorite shirt and using her hairbrush. Lucy asked Gwen what Kevin is like, and she responded saying he's the worst since he's so tough and bad. Lucy believed Gwen liked Kevin and started to tease her, but she denied it.

In From Hedorium to Eternity, Lucy was at Ben's house along with Ben and Gwen. Lucy. along with Ben, Gwen, Cooper, and Jonesy teamed up with Kevin underground. Lucy helps to defeat Zs'Skayr. Lucy teased Gwen about liking Kevin which caused Gwen to chase her.

Omniverse

Lucy returned in Mud Is Thicker Than Water, where she was brought in by the Plumbers to pose as Liam to find out who the mole in Plumber HQ was. Gwen was convinced that Lucy herself was the mole (due to her feelings towards Lucy from when they were kids), but Ben defended her asking Gwen if Lucy is truly capable of such actions and that "Cousin Lucy is awesome". The Plumbers attempted to bait Psyphon's gang into coming out into the open by transporting a fake Annihilarrgh (the real one was revealed to have been rebuilt by Blukic and Driba). Gwen truly believed that Lucy was the spy and that she was behind the sabotage at the base, until Lucy revealed 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) battled Psyphon and his gang. Lucy impersonated Vilgax and terrified Psyphon before tripping him with some of her sludge and leaving Crashhopper to defeat him. Gwen then apologized for suspecting that Lucy was the traitor, Lucy forgave her on the basis that they are family and promises to return the favor when she was promoted to commanding officer. Gwen laughed at the prospect of this, but quickly became serious and worried when she realized that Lucy was possibly not joking. Lucy walked off and laughed while Gwen nervously chased after her.
