The Leviathan Moya was subjected to a hybridization experiment by the Peacekeepers while in captivity. A synthetic stimulant/conceptive was placed in her by a peacekeeper Leviathan expert called Velorek, leader of the experiment. It was accidentally released by Ka D'Argo six months after their escape from peacekeeper captivity, leading to the conception of a fetus. Roughly six months later, Moya gave birth to a baby Leviathan, though the baby was far from normal: unlike typical Leviathans, which are streamlined and have no weapons whatsoever, the infant was "covered with weapons." During the birthing process, Talyn's external weaponry caused him to become stuck in the birth canal, and he had to fire a low-yield shot from those same weapons to free himself. Shortly after his birth, he had a few disagreements with his mother and refused to talk to her. Moya felt that a Peacekeeper should talk to him. Aeryn boarded Talyn and succeeded in convincing the young Leviathan to listen to his mother. Moya asked Officer Aeryn Sun to name her offspring, and Aeryn named it after her father, Talyn.
