Kayla (Earth-Prime)

"We can't stay here. Do you understand? I am trying to protect our children. I'm not leaving without my kids. I'm not abandoning my friends or this planet. You know, I could just snap your head off and take that stupid button of yours. Yeah, but you won't. There's a part of you that cares."

- Kayla and Mick Rory

Kayla is a Necrian warrior and an ex-bounty hunter hired by Bishop to abduct the finest specimens across the universe for his hybrid expansion, one of those being Sara Lance.

Early Life
Kayla was born to Kamaya and Kyle on Necria, where she was raised to become a fierce warrior.

On Kayla's 300th rotation, her mother, gifted her ship.

Engagement
At some point, Kayla became the boss of Gary Green and was engaged to him. Later, they kidnapped countless aliens across the cosmos, including Spartacus, a human gladiator from the past, who was kidnapped to serve as Kayla's food.

Kidnapping of Sara Lance
In 1977, Kayla brought her ship to London and kidnapped Sara Lance. They then placed her in a cryo pod and were attacked by Lance and Spartacus after their escape from their pods. However, Spartacus' reckless actions allowed Kayla to grab him using her tentacles, eventually swallowing him. She then sent Green to inspect further escapees.

As Green returned to the cockpit and talked to Kayla, she left and inspected the cryo pods, finding out Lance was missing. Surprisingly, she appeared behind her and fought Kayla using a pipe. Unfortunately, she failed, and Kayla was able to lock her back in a cryo pod until her subsequent escape. Lance then opened the airlock and sucked Kayla out to the portal to the Temporal Zone.

Landing on Earth
Kayla later entered one of her pods and landed on the Sierra Maestra Mountains in 1962. She was then taken by the Cuban Armed Forces and experimented on. The Legends soon arrived, and Ava Sharpe prevented her death with aesthetic gas. Kayla woke up and attacked Sharpe, only to be defeated by Mick Rory with his Heat Gun.

Afterward, Kayla went to Fidel Castro's office and attempted to assassinate him. Behrad Tarazi used his Air Totem and rescued Fidel Castro.

Kayla then sought a spaceship and thought the missile was a spaceship. Rory used Spooner Cruz's powers to convince Kayla to take the Waverider instead. Kayla took took the plutonium from the missile and boarded the Waverider with Rory. She powered the Waverider with the element and allowed the two to travel to Pliny X-19 in search of her ship and Sara Lance. However, Rory was unable to understand Kayla until she activated her Image Inducer. Rory was impressed by Kayla's strong metabolism, allowing her to drink stronger alcohol.

Searching for Fuel Cells
Days later, Kayla and Rory arrived on Pliny X-19. Rory attempted to make Kayla wear an oxygen mask, with Kayla throwing the mask away and exiting the cargo bay, claiming the environment is Earth-like. Kayla inspected her ship and determined the damage. Kayla and Rory searched for fuel cells within the Electrostatic Barrier. However, Rory's impulsive decision to search for Lance led to his capture by the AVA Troops. Kayla quickly ran to the Waverider, only to find it being taken by Amelia Earhart.

Now with no way to escape, Kayla stole a power cell and was affected by the sudden deactivation of the Electrostatic Barrier. Rory, who escaped from being tied to a tree, shared his oxygen mask with Kayla and returned to Kayla's ship. They entered a pod and made-out, with Kayla's tentacles entering Rory's ear and laying eggs.

Escape from Pliny X-19
Hours later, the Zagurons left the ship and the two exited the pod. Kayla promised Rory to leave when the third moon on the planet rests. Rory ran and attempted to rescue Lance from Bishop. Despite her promise, Kayla left before the moon rested due to the Zagurons causing damage to the ship. Luckily, she was able to rescue Lance, Rory and Green from the Zagurons. Kayla arrived and reverted to her true form, fighting Zagurons and eventually went missing. Rory refused to leave without Kayla until Lance convinced him that they would wait for her on the ship. Unfortunately, Kayla never returned, and the trio left the planet in a ray of light.
