Elektra Kyle was a daughter brought up in the tough streets of Cairo, whose father was an ambassador for United States of America. After his assassination, Elektra was taught the martial art of ninjutsu and took the alias Catsai. Hired by Tombstone the Ravager to assassinate Dare The Terminator, she and Dare struck up a friendship and killed Tombstone instead.
The two began to work alongside one another, and both went to assassinate The Big Question, the crooked mayor of New Gotham City. Although she has no actual superpowers, Catsai is an expert with bladed weapons like Dare.
Catsai holds a love for cats and has a very sadistic streak about her, with "shadow-warrior grace and dominatrix passion". In a possible future, Catsai becomes the mother of the hero known as Wild Hunt.
