Chen Tiejun was one of the genetically enhanced Human "superwomen" that were bred in the Chrysalis Project on Earth in the late 20th century. She later founded a matriarchal colony on a remote island off the coast of New Zealand.
She and her group of "Amazon warriors" were instrumental in Gary Seven's plan to destroy Khan Noonien Singh's newly-bred lethal bacteria that would destroy the Human race entirely—with the exception of the Chrysalis supermen. Chen and most of her fellow warriors died during the attack on Khan's "Chrysalis Island", Muroroa, in 1995. (TOS - The Eugenics Wars novel: The Rise and Fall of Khan Noonien Singh, Volume 2)
