One of the three women Harry Mudd was transporting as wives for lonely settlers in 2266, whose beauty depended on the illegal Venus drug and who ended up among the miners of Rigel XII.
Magda Kovacs appears in the episode Mudd's Women. She comes from the Helium Experimental Station, a place she says offered a woman no prospects, and has signed on with Harry Mudd in the hope of finding a husband on a frontier world.
Rescued from Mudd's disintegrating ship along with Eve McHuron and Ruth Bonaventure, she has a hypnotic effect on the men of the Enterprise. On Mudd's instructions she charms information out of the crew, lifting a communicator so that he can contact the lithium miners of Rigel XII and strike a bargain behind Kirk's back.
Like the others she owes her allure to the Venus drug, and without it she looks worn and plain. On Rigel XII she is paired off with one of Ben Childress's two partners and remains there. She was played by Susan Denberg.
