Kati was a genetically-engineered Augment from Earth's 20th century, follower of Khan Noonien Singh, and survivor of the Eugenics Wars. Kati escaped Earth aboard the SS Botany Bay in 1996.
In 2267, the Botany Bay was discovered in suspended animation by the USS Enterprise, where Kati was one of thirty women among the seventy-two surviving members of Khan's original group of eighty-four.
She was initially revived by Khan, whereafter she participated in the attempted takeover of the Enterprise. She was then sent to Ceti Alpha V with the rest of Khan's people after their attempt to capture the Enterprise ultimately failed. (TOS: "Space Seed")
Kati was played by actress Kathy Ahart, who was credited simply as "Crew Woman".
