Created by Richard Donner and Mario Puzo for Superman and Superman II, Miss Teschmacher, portrayed by Valerie Perrine, is one of Lex Luthor's two main assistants, alongside the bumbling Otis. She operates from Luthor's subterranean lair beneath Grand Central Terminal, aiding Luthor in his plan to destroy the West Coast of the United States using hijacked nuclear missiles in order to increase the value of his desert land holdings. Despite her complicity, she shows reluctance when Luthor reveals he is willing to let millions die—including her mother who lives in Hackensack, New Jersey. After Superman is weakened by kryptonite and left to die, Teschmacher, disturbed by Luthor's cruelty and attracted to Superman, removes the kryptonite and rescues him, on the condition that he first intercepts the missile headed toward Hackensack.In Superman II, she reappears as Luthor escapes from prison and infiltrates the Fortress of Solitude. Although her role is reduced, she continues to show dissatisfaction with Luthor's obsession with power and his disregard for human life. She ultimately abandons Luthor after he allies with General Zod and betrays her trust.
