Catwoman (Injustice)

Selina Kyle a.k.a Catwoman is one of characters who appears in the comics Injustice: The Regime, She was formerly part of the regime of the now deranged Superman but soon defected and join with the Insurgency afterwards.

Injustice: Year One
Selina appears as one of the first Insurgents to aid Batman in his fight against Superman. She recruits Black Canary to the cause as well. She supports Batman and acts as a confidant, but is still uneasy that he refuses to tell her some things, namely how Bruce knew Hawkgirl's whereabouts when they kidnapped her.

Catwoman later helps disperse a mob of cultists that Superman had inadvertently created after saving Earth from countless Parademons from Apokolips.

When Batman details his plan to infiltrate the Fortress of Solitude and take one of the Super-Pills, Selina is among the Insurgents to go with him, including Captain Atom, Green Arrow and Black Canary. When Green Arrow becomes separated from the other Insurgents after the ceiling caves in, Selina tries to convince Dinah that they need to leave in case Superman comes back.

After both Nathaniel and Oliver have died and the remaining Insurgents return to the Insurgency Base, Selina attempts to convince Bruce not to go to the Batcave, for fear of Superman's heading there to kill Bruce. In response, Bruce kisses Selina and uses a sleeping gas to subdue her.

Injustice: Year Two
Catwoman serves as a member of Oracle's new Birds of Prey in order to mount a resistance in Gotham City after Superman sent his soldiers there.

When the Insurgency/GCPD strike force attacks the Hall of Justice, Catwoman disguises as one of the Regime soldiers. After Harley Quinn detonates a bomb to destroy the entrance to the hall and allow the strike force inside, Selina is flung into the structure but is rescued by The Flash. However, she injects a drug into his neck which knocks him unconscious. She is then confronted by Robin, who attempts to unsettle her with snide remarks about Bruce and the rest of the Insurgents. She defeats Robin, and takes him to a secure location in the Tower of Fate.

Injustice: Year Three
Catwoman continues her membership in the Insurgency and aids Batman alongside the former Birds of Prey and magicians of the Insurgency.

Epilogue
''At last, Superman had paid for what he had done to Catwoman. Feigning allegiance to his Regime had cost Selina her beloved Batman and her best chance at happiness.'' ''Pride and anger kept her from attempting reconciliation with Bruce Wayne. But his inspiring reconstruction of Gotham and Metropolis fostered in her a desire to remain close to him. Until she was ready to approach him again, she did her part to keep Gotham's streets clear of crime. Nascent underworld organizations had both the the Bat and the Cat to fear.''
