Madame Rouge is a villainess from the DC franchise.
Origin in the comics
Laura De Mille was originally a French stage actress until an automobile accident caused her to sufffer multiple personality disorder where she have a dual good/evil split personality. At this point, she attracted the notice of The Brain and his associate Monsieur Mallah. With Mallah's help, the Brain performed surgery on De Mille that was, from his perspective, successful, sublimating her good personality and allowing her evil personality to remain dominant. As Madame Rouge, De Mille became the only female member of the Brotherhood of Evil, and assisted the Brotherhood in its continuing conflicts against the Doom Patrol. At first, Madame Rouge was simply a master of disguise; subsequent surgery by the Brain eventually gave her the ability to alter her appearance and stretch her limbs.
Later, Rouge's split personality manifested again, with her good personality occasionally appearing. Rouge was romantically linked to the Doom Patrol's leader, Niles Caulder ("The Chief"), who was able to help Rouge overcome her evil side and ally with the Doom Patrol.
Ultimately, Rouge's mind reverted to its evil state, causing her to seek vengeance against both the Brotherhood of Evil and the Doom Patrol for their previous interference. She was apparently successful in murdering both groups.Years later, Robotman and the Teen Titans tracked down Rouge and her ally, General Zahl. Beast Boy (then Changeling) killed Rouge, although at the moment of her death, her good side apparently manifested; she forgave Changeling and called to Niles, her apparent true love.
Madame Rouge's daughter, Gemini, also a shapeshifter, appeared years later to seek revenge against Beast Boy. In Blackest Night, Madame Rouge has been identified as one of the deceased entombed below the Hall of Justice. Madame Rouge's corpse is revived as a Black Lantern during the event.
Even before she gained her powers, Madame Rouge was a deadly opponent for the Doom Patrol. Originally a beautiful French actress named Laura De Mille, this mad mallable mistress was born out of a car accident that gave her a split personality...something the Brain and Monsieur Mallah used to their advantage.
Recruited into the Brotherhood of Evil, Madame Rouge was a ruthless adversary for the Doom Patrol. To make her able to match their abilities, the Brain performed an experiment on Rouge, giving her the power of super elasticity, and shape shifiting abilities. The Doom Patrol's leader, the Chief, the man she was secretly in love with, tried to help her fight her evil side, but alas, it was too strong, and she turned on the Brotherhood. In the original DP's last adventure, Rouge and her associate, General Zahl, seemingly murdered both groups and got away with this horrific deed (although Robotman, Negative Man, the Chief, and the Brotherhood all survived, with the exception of Elasti-Girl)...or so they thought. Years later, Rouge met her end at the hands of Elasti-Girl and Mento's foster son, Beast Boy, when he killed her in battle, avenging Elasti-Girl's death
