Selina Kyle

Selina Kyle is a teenage girl and is a skilled street thief residing in Gotham City. Known under the alias of Cat, she is well known around the city through her connections in the criminal underworld and around the streets. She witnessed the murder of Thomas and Martha Wayne after a pickpocket incident which led her into the alley as she watched Bruce Wayne have his parents murdered in front of him, sparking an interest in him. After suffering from a near-death experience, she forms a partnership with Barbara Kean and Tabitha Galavan. Although she usually prioritizes her own survival above all else, she increasingly fluctuates between her loyalty to the Sirens and her personal affection for Bruce until she is critically wounded by Jeremiah Valeska, leaving her with possibly permanent spinal damage.

Early life
Selina is a young orphaned street thief with a fascination with cats. When she was five, her mother abandoned her at St. Maria's orphanage, but Selina never believed she was dead. At some point in her life, Selina befriended Bridgit Pike and Ivy Pepper.

Witness to a murder
Selina Kyle is running over rooftops in Gotham City before stopping to look down; she sees something and smiles before leaping off and then sliding down to the sidewalk. She walks up behind a woman carrying a paper sack of groceries, opens up a switchblade knife, and cuts open the sack. When the groceries spill out, Selina quietly steals a quart of milk that drops out and walks away. Then, she passes by a man and takes his wallet. When the man chases her, she climbs up a fire escape and the man gives up and goes to report it. She then comes down a fire escape near the Theatre District to give milk to a stray cat, running up the fire escape upon seeing the Wayne family entering the alley after they leave a movie theater. There she witnessed the deaths of Thomas and Martha Wayne.

Later, she is observing the Waynes' funeral from above a mausoleum, taking off her hood in respect. She is then on the wall outside the Wayne mansion. Selina is under a railroad underpass, playing with a necklace. She, along with a group of homeless kids are approached by Patti and her partner, Doug. Patti introduces herself as a member of a Homeless Outreach Program organization headed by Mayor Aubrey James. Doug starts giving out food to the homeless children; however, Selina is cautious and refuses to take any. Upon seeing Patti drugging the teenagers, Selina discretely escapes, leaving the teenagers behind. The next morning, Selina observes Detective James Gordon from behind a fence, perched on a rooftop ledge. After the case had been supposedly "cracked", Selina along with other homeless children, are escorted from their shelters, into GCPD vehicles. Selina is in a line leading to a bus that will take her upstate to a Juvenile Detention Center. While talking to a female chaperon, she states that "there had been a mistake" and that she is incorrectly being sent to juvie. She demands to talk to James Gordon, but the chaperone tells her "you'll be allowed a phone call once up-state". The chaperon, who asks for her name, dismisses her onto the bus, listing her as 'Jane Doe'. Upon seeing Patti enter the bus, Selina bolts for the rear exit; she is held at gunpoint and is forced to sit back down. After the bus arrived to its undisclosed location, and the children were mustered into cargo containers, Selina hides inside the bus, narrowly avoiding Patti who was searching the bus for a missing child. She attacks one of the men working with Patti, scratching his eyes out to the point where the sockets appeared empty. After searching the entire premises, Patti finally manages to catch Selina. Patti holds Selina at gunpoint, Patti is then tackled by James Gordon.

Selina is in the GCPD Headquarters, where she is arguing with an officer about being sent upstate. The officer tells her that aside from having outstanding warrants, she is 13 years old with no legal guardian. Selina tells him that she has a mom somewhere even though the officer reads that her mom is deceased. She manages to get the officer to call Detective Gordon over and proposes a trade; she gives Gordon something he "really wants" and he gets her out of juvie. She tells him, "I saw who really killed the Waynes, saw him clear as day."

A man from juvenile services brings Selina to GCPD and puts her in Gordon's custody; Gordon then takes Selina to the alleyway where the Waynes died. When she asks him why he cares who killed them, he says that he wants to see the killer brought to justice; she scoffs at this and he tells her that he made a promise to Bruce. She describes how the Waynes were killed and then tells him that she saw the killer's face because she can see in the dark. She also explains the pick-pocketing she performed leading up to her being in the alleyway. When she tells him that she chucked the wallet she stole into the sewer, he handcuffs her to a stairway while he goes down the sewer to investigate. Gordon is unaware that Selina had stolen Harvey Bullock's pen and she uses it to escape the handcuffs. Selina drops the handcuffs down the sewer, tells Gordon that she will need them, and runs away.
