In her only appearance in the series, she wants aid from Mouse and Skillet after her gunfight with them. She talks about people who find the New Angel and "get out". That night she gave Mouse the only thing that could kill her (apparently a large silver bullet), then turned into a werewolf like creature called she-wolf, though her fate is unknown after she was transformed. On the surface, she appears to be transsexual, because of her shaved beard, chest hair and very raspy voice.
She is voiced by Ted Murphy in her only appearance.
Physically she is depicted as a tall woman with high-heeled shoes and fishnet stockings, with two pistols and a rifle. She has red colored hair and she wears black bikini-like clothing.
- "Enter the Sandmouse" (only appearance)
- Her design and character resemble something out of Aqua Teen Hunger Force, Matt Maiellaro's other Adult Swim show.
- Her name is misspelled "Leigh", on sources and websites related to the show such as 12 oz. Mouse Central.
- On a transcript on the 12 oz. Mouse Central website related to "Enter the Sandmouse", the transcript calls her "Gun Woman" instead until she says her own name. It uses the same incorrect "Leigh" name instead.
- She mentions three other people to Fitz and Skillet, their names are "Brandy", "Breezy", and "Butterfly" who "got out" and found the New Angel. This is never explained or mentioned again in the series.
- This character is most likely non-canon to the series since she doesn't appear or is referenced in "Invictus" and Season 3.
- She's possibly voiced by a second person due to their being an echo in her voice every time she spoke.
