Catwoman is a recurring antagonist in the DCAU. She is a thief who Batman tries to stop and has a romantic fellings towards. She is also an activist.
As a cat-burglar, Selina Kyle ran through Gotham, stealing precious items of value, such as jewels. Catwoman's crimes were quick and efficient until Batman intervened. Though he failed to catch the thief, Catwoman was impressed, and quickly became infatuated with the Dark Knight.
Selina had intended to set up a wildlife preserve, but industrialist corporation Multigon purchased the land from under her and set the foundation to build a resort. Though she and Bruce argued with the Multigon execs, their efforts were fruitless. Meanwhile, Catwoman broke into the complex. Though she was careful, she had been caught in the act: Red Claw sent spies to follow the burglar, and they discovered her secret: Catwoman and Selina Kyle were one and the same person.
Assassins attempted to kill Selina on the highway, but Bruce Wayne's evasive driving saved them both. Catwoman became ever concerned about the true nature of Multigon, and broke into the facility created in the mountains. She was captured, and tied together with Batman. Red Claw had stolen a plague and activated it to kill the two.
