Teschmacher has subsequently made further appearances in film, television, and comics, including the television seriesSupergirl, portrayed byAndrea Brooks,[2][3][4] and the filmSuperman (2025), portrayed bySara Sampaio.
Created byRichard Donner andMario Puzo forSuperman andSuperman II, Miss Teschmacher, portrayed byValerie Perrine, is one ofLex Luthor's two main assistants, alongside the bumblingOtis. She operates from Luthor's subterranean lair beneathGrand Central Terminal, aiding Luthor in his plan to destroy theWest Coast of the United States using hijackednuclear 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 inHackensack,New Jersey. AfterSuperman is weakened bykryptonite 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.
InSuperman II, she reappears as Luthor escapes from prison and infiltrates theFortress 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 withGeneral Zod and betrays her trust.
Eve Teschmacher appears inSuperman (2025), portrayed bySara Sampaio.[5] This version isLex Luthor's girlfriend who previously datedJimmy Olsen, who she still stays in contact with. Having grown disillusioned with Luthor's plan to defameSuperman and take over the country ofJarhanpur, she sends Jimmy a collection ofselfies that contain incriminating information against Luthor in the background. Luthor finds out about her correspondence with Jimmy (though not realizing the hidden in plain sight background documents), and imprisons her in an artificialpocket universe, while Jimmy's friendLois Lane releases the images on theDaily Planet's website. After Luthor is arrested and his plans are thwarted by Superman and theJustice Gang, Eve is freed from the pocket universe and resumes her relationship with Jimmy.
Tess Mercer, acomposite character based on Eve Teschmacher,Mercy Graves, andLena Luthor, appears inSmallville, portrayed byCassidy Freeman.[6] She is introduced after Lex Luthor's disappearance and is appointed CEO of LuthorCorp. Tess is responsible for executing Lex's remaining plans, managing his covert operations, and protecting his legacy. She conceals his involvement in illegal experiments, including those related to the cloning of Lex. Tess operates as Lex's proxy, delivering messages, enforcing threats, and negotiating withClark Kent andOliver Queen. She infiltrates the Veritas society, attempts to control alien technology, and works with the Checkmate organization. Though she begins as a loyal operative, she gradually resists Lex's influence, questions his methods, and pursues her own objectives. Her shifting loyalties place her in direct conflict with both Lex and his enemies, leading to her eventual betrayal and death at Lex's hands.
Eve Teschmacher (Andrea Brooks) appears inSupergirl as media executiveCat Grant's and later CEOJames Olsen's assistant. Teschmacher also serves as assistant to corporate scientistLena Luthor when Lena conducts research onBlack Kryptonite at L-Corp and later the DEO to produce superhuman abilities in humans. Teschmacher is later discovered to be a mole sent by Lex Luthor. After Lex is killed, Teschmacher tries to flee but is coerced into working for covert organizationLeviathan as their assassin after her father is killed. Lena captures her and uploads the artificial intelligence Hope into her brain, enabling Hope to control Teschmacher's body. After an attempt to use a weapon satellite, Hope in Teschmacher's body takes the blame and Teschmacher is arrested by the FBI. Lex, now returned to life, persuades her to work as his mole while providing protection for her mother and offering to identify who killed her father. Teschmacher serves as Lex's accomplice, and is tricked into killing former DEO agent Jeremiah Danvers, who Lex claims killed her father. Lex later reveals his lie and blackmails her with the footage. Teschmacher is followed by investigative journalist William Dey but Teschmacher captures and wounds him. Teschmacher is subdued by Lena and Supergirl learns that Lex manipulated Teschmacher and sympathizes with her. Teschmacher's testimony at Lex's trial is discarded due to her emotional involvement with him.
Teschmacher has been subject to academic analysis, including the interpretation that her first name functions as a reference to the biblical Eve, reinforcing her thematic role as a morally ambivalent woman influencing powerful men.[7][8]
