Ko Sai 科·赛|
The chief scientist of the Kaminoan cloning project. Ko Sai oversaw the biological aspects of the Republic's clone army, ensuring that the clones were of the highest quality. Under her guidance, the clones' genetic code was altered to accelerate their growth to twice the normal human rate, and their mental structure was subtly reconfigured to make them obedient to authority. Her black cuffs were a mark of honor, their thickness indicating her high scientific rank. Early in the Clone Wars, Ko Sai went missing and became the subject of intense searches by the clones, Chancellor Palpatine, and other Kaminoans. Each had their own reason for seeking out Ko Sai: For the Republic, it was imperative that her methods not fall into enemy hands. Palpatine quietly sought a genetic solution to immortality. For Kal Skirata, finding Ko Sai meant unlocking the mystery of the growth acceleration that doomed the clone troopers to a shortened lifespan.
Skirata's agents found and imprisoned Sai, destroying her collected research and demanding that she reveal which genes held the secret of the clone growth acceleration. While Ko Sai eventually agreed to cooperate, she committed suicide, hanging herself before turning over all her information.
