Growing up an orphan in one of Gotham’s worst neighborhoods, Selina turned to a life of crime to not only keep herself alive but her friends as well. The vivacious villainess elevated cat burglary to an art form, stealing whatever may be necessary—and sometimes even more—to survive and protect those closest to her. Utilizing a cat mask and suit to steal from the city’s rich and corrupt, she's a master at hand-to-hand combat and acrobatics, stealthy as a ninja and an expert at breaking and entering.
