Cat-Woman (Earth-43)

Selina Kyle (Earth-43) is the alternate version of Selina Kyle from the world of Earth-43, where Batman became a vampire to defeat Dracula (Earth-43).

History
While out walking one night, Selina is attacked by the vampire Creach- Creach being one of the few surviving vampires after the majority were killed in the destruction of the Batcave-, who turns into a wolf to hunt her. Although he bites her in his wolf form, Selina escapes him by falling into a river, subsequently returning to her apartment to collapse.

Upon awakening, Selina discovers that she now transforms into a cat-creature in the light of the full moon, leaving her resolved to rip apart the monster that turned her. While out hunting that night, Selina encounters Batman as he hunts for the remaining vampires. Although Batman initially rejects her offer of help, his increased trouble in dealing with his thirst for blood prompts him to contact Selina, her subsequent devotion to him as she holds him through his pain helping him to overcome his thirst.

With Selina now having joined Batman's fight against the vampires, the two learn that the attacks are being coordinated by the Joker, who has taken control of the vampires, prompting Batman to contact his daylight allies to stake the Joker's minions during the daylight. With the Joker down to only fifteen vampires, he lures Batman and Selina into a trap, only for the two to easily defeat the vampires, Selina even killing Creach during the fight. However, just as Batman kills the last vampire, the Joker fired a crossbow bolt at him, Selina only preventing it killing Batman by throwing herself into its path, her last words being to assure Batman that the 'long night' they shared was good while it lasted.

Legacy
Despite Selina Kyle's positive- if brutal- attitude and history in this universe, her legacy was horrifyingly dark. With her death having removed Batman's last hope at finding human compassion in his current state, he finally lost control of his bloodlust, drinking the Joker's blood and leaving him as damned as all other vampires.

In Bloodstorm's sequel, Crimson Mist, the now-corrupted Batman reflects grimly that he can no longer understand Selina's noble sacrifice after his psyche has become increasingly corrupted by his surrender to his vampire side, regarding it as a foolish action rather than th eselfless nobility it once was.

Powers & Abilities
Although her civilian skills and life were never explosed in depth in this universe, as a were-cat Selina possessed enhanced strength, speed, and senses, sufficent to challenge even trained vampires with no hints at her possessing combat training herself. However, she could only transform at night- it was unspecified if she would have transformed under any moon but a full one as she died before the nights of the full moon could end-, and she apparently retained human vulnerabilities, as shown when she was killed by a simple wooden crossbow bolt despite the superstition of were-creatures only being vulnerable to silver weapons.
