Camille was originally simply a normal high school duck, with a personality that left her an outcast. She developed a fascination with chameleons and their ability to adapt to any environment. She extracted the essence of the chameleon, gaining the power to shape-shift. She also retained chameleon attributes, such as green feathers, a tail, and a lisp.
Camille's experiments were expensive, and she was still unable to interact with people and hold a job. So Using her shape-shifting powers, she attempts to create her own money by posing as Mrs. Howl, owner of a large newspaper chain. This led to a second confusing encounter between the heroes and the criminal, with Camille quickly imitating Gosalyn, Launchpad McQuack, and even Darkwing Duck himself as she attempted to flee the scene and/or capture them. It got so bad that Darkwing almost beat up Honker, and Launchpad actually clobbered DW inadvertently in attempting to subdue the criminal.
The situation was resolved when Honker Muddlefoot, himself suffering an identity crisis thanks to Darkwing's egotistical meddling, realized that if Camille had taken on the traits of the chameleon, that she had also become cold-blooded. Turning up the heat in the room caused the criminal to lose control over her metabolic rate and her changeling abilities and to lose her disguise, rapidly shifting between forms out of control. It culminated in Camille degenerating into a small chameleon lizard, easing her capture. Darkwing would sentence her to "ten years in a maximum strength terrarium."
Boom! Studios comics
Being a one-shot villain on the show, Camille never appeared in any Darkwing Duck comics published when the show was on the air, but she eventually made the jump to the print medium in Boom! Studios' DuckTales comic book, appearing in the arc "Rightful Owners". Camille first appears disguised as King Fulla Cola's son and tries, with the help of the Beagle Boys, to steal the candy-striped ruby (Rockerduck sent both her and the Beagle Boys after Scrooge to prevent him from returning the ruby). At the start, she seems to have the upper hand and easily defeats Scrooge McDuck and his nephews; however, at the end despite all her attempts to steal the ruby fails, and Scrooge manages to return it to its original owner. She then tries to escape with a submarine which she manages to do successfully, only to be thwarted and caught by the Navy.
Camille reappears in the DuckTales/Darkwing Duck crossover story "Dangerous Currency", where she is a member of "The League of Eve-ill" along with Magica De Spell, Ammonia Pine, and Cinnamon Teal. They are in an alliance with The Phantom Blot, the Fearsome Four, and the Beagle Boys. They are also later joined by Negaduck. However, "Dangerous Currency" was never approved by Disney and is not considered canon (this likely applies to "Rightful Owners" as well).
- Camille's last name refers to a chameleon, a lizard that can change colors.
