Kayla is a Necrian who was the boss of Gary Green as well as his ex-fiancée. She assisted Bishop in kidnapping various creatures throughout the universe, including Sara Lance. Kayla is also the girlfriend of Mick Rory. After Bishop died, she and Mick left the Legends to raise their kids.
Abducting aliens and people
Kayla has been using her ship to abduct and confine different aliens and humans, such as Spartacus. In London in 1977, Kayla abducted Sara Lance. She worked for another whom Gary described as a "power hungry space lord".
She was later attacked by Spartacus, who escaped, but she impaled him with one of her tentacles and then ate him alive. Kayla then sent Gary to check on the containment cells. After Gary returned, she went to check on the cells herself. There, she was confronted by Sara who threw a pole at her, which she caught before starting to fight against Sara. After she won the fight against Sara, she put her back in her cell, but Sara broke out again and sent Kayla flying through space right into the temporal zone, together with multiple containment cells. Kayla sheltered herself in a cryochamber to survive.
Landing in Cuba
When Lord Knoxicrillion describes his abduction by Kayla, Mick Rory gets the idea to find her to find Sara. Following that idea, Mick and Gideon find information on Kayla, leading them to 1962 Cuba.
Meanwhile, Kayla's cryochamber lands in Cuba, 1962 and she is captured. Ava Sharpe saves her from being vivisected, but Kayla awakens and attacks Ava, before Mick uses the heat gun to save her and makes Kayla run. Kayla runs to the office of Fidel Castro but she is repelled by Behrad Tarazi wielding the Air Totem.
Kayla sought a spacecraft to leave Earth, but thought a missile was one instead. With Spooner as a translator, Mick talked Kayla into boarding the Waverider with the plutonium from the nuclear missile, so the ship has enough fuel for their trip. Mick and Kayla go without the Legends. So Mick can understand what Kayla is saying, she wears a transmografication ring to assume a human form.
Kayla and Mick took the Waverider to the planet governed by Bishop and flew into the section that had an artificial atmosphere; the rest of the planet was hostile to most forms of life. Kayla determined that her ship was damaged and needed a new fuel cell to operate. Mick was interested in rescuing Sara so he went arrogantly against the AVA Clones that were nearby and was captured. Before Kayla could return to the Waverider, it was stolen by someone else.
Kayla steals a battery, but, as she is dragging it to her ship, the atmospheric dome disappears and Kayla is exposed to poisonous gas. Mick, who notes that he is not strong enough to move the battery alone, appears with a breather which they share.
Just as the two arrive to her ship, Zagurons surround them. Kayla and Mick hide in a cryochamber and Kayla admits that she fears the Zagurons. Alone together in the cryochamber, Mick and Kayla make-out, with Kayla switching between forms. During this intercourse, Kayla laid her eggs in Mick's head through via his ear canal during intercourse with her tentacles, making him the host of her eggs.
