Arianna Carlin

Arianna Carlin is the main villainess from the episode of Lois and Clark: The New Adventures of Superman titled, "Madame Ex." She is the ex-wife of Lex Luthor. She was played by Emma Samms.

Seeking revenge for the death of her ex-husband, Lex Luthor, Arianna takes a woman who was in an auto accident and has her undergo plastic surgery to look exactly like Lois Lane, and sends her out to slander Superman's good name in public, while Arianna lands a job at the Daily Planet. As for the real Lois, the evil Arianna later captures her, and attempts to kill Superman with a kryptonite-laced bullet. Both she and the Lois clone get away afterwards, but Superman (sans kryptonite bullet) apprehends both villains.
