Nocturna (real name: Natalia Knight) is a criminal in Gotham City who kills her victims by draining their blood and allowing them to bleed to death. She appears in the first season of CW's Batwoman.
She is portrayed by Kayla Ewell, who also portrayed Caitlin Ramirez on The Bold and Beautiful.
Natalia Knight was born in 1992 or 1993 with a unique type of porphyria, which means that she cannot be exposed to sunlight and her kidneys have trouble cleaning her blood. She was adopted by Charles Knight.
Birth of Nocturna
After her adoptive father, the man who would often provide Natalia supplies of fresh blood, died of a heart attack, Natalia needed fresh blood because of her disease and started to kill people by seducing them, draining their blood and then leaving them for dead. After she killed two club-goers in Gotham City, she was dubbed by the media as "Nocturna".
When Nocturna tried to kill another person, she was confronted by Batwoman. Whom she got into a fight with. Nocturna bit her in the neck, injecting ketamine in her blood to subdue her. She then hung Batwoman up, but before she could drain her blood, she had to flee from Crows Security.
When she saw Alice outside of the Hold Up, she followed her to her hideout were she subdued her. After tying Alice up, she was seduced by Alice to attack Mary Hamilton instead of draining her. She wanted the blood from the Desert Rose-cure Alice gave to Mary. Nocturna attacked Mary and took her to the Gotham Cathedral Church. When Batwoman came there to free Mary, Nocturna engaged her in combat with a candle holder. After a short struggle, Natalia pinned her down and was about to bite her but was knocked away by Alice who kicked her in the face. As she tried to run away, she was confronted by Batwoman again. Batwoman confronted her about her killings to which Natalia said she did not deserve to die and justified her deeds by telling her victims partied their lives away while she suffered. Nocturna fought Batwoman again with a wooden shelf but Batwoman beat her by recreating sunlight with blacklight and burning her face before cuffing her to the cathedral. She was then picked up by the Crows and brought to Arkham.
Suffering from terrible health problems her entire life, Natalia was fostered by her adoptive father her entire life. After he died, she needed fresh blood in order to combat her disease. She began to seduce partygoers for fresh blood. She justified her killings by stating that she suffered health problems while they were healthy but choose to ruin their bodies with booze and drugs. Natalia seemed to take some joy out of her killings as she mocked a captured Batwoman repeatedly when defeating her and was about to drain her blood.
