She is a member of a telepathic alien species with a life span of only nine years. She leaves the ship in the fourth season after her powers threaten to destroy it. She reappears in an episode in the sixth season and features in Star Trek: Voyager novels and short stories. Voyager's creators intended Kes to provide audiences with a different perspective on time.
