Selina Kyle

Selina Kyle is a mysterious figure who is quietly infiltrating Gotham’s seedy underbelly to further her own agenda. She is a flirtatious thrill-seeker who loves danger and evading capture. Her fierce attitude and tenacious agility are the perfect tools to excel as a cat burglar, but hidden underneath the array of identities and the motorcycle leathers is a protective soul who’s more at home with the city’s strays than its citizens.[3] Like the Batman, Selina also isn't afraid to explore the darkest corners of Gotham City in the pursuit of justice—or if she feels that that's not a realistically possible outcome—coldblooded revenge.

Selina carries a personal vendetta against her father Carmine Falcone due to him allowing her to go into the foster care system after her mother was murdered via strangulation despite them both knowing that she was his illegitimate daughter. This grudge would eventually lead to her plotting to steal his money believing that it's owed to her for years of neglect. It's not until later, when it's revealed that he was the one who had Selina's roommate Annika Kosolov kidnapped and personally strangled that she connected the dots and realized that Carmine had also likely murdered her mother. Consumed with rage over Carmine repeatedly ruining her life, she snaps and tries to take justice into her own hands by attempting to kill him.

Due to her neglected childhood, Selina has a strong hatred for the rich people of Gotham. She even says the Riddler is not entirely wrong in killing all the corrupt political and millionaire people and believes that he's actually doing the city a favor by uncovering all of their dirty secrets.
