Panamanian-born American actress (1952–2018) who played Ardra, the confidence trickster posing as the devil of Ventax II, in the Next Generation episode Devil's Due.
Marta DuBois was an actress with many American television credits, among them a recurring part in Magnum, P.I. as the hero's wife Michelle.
In Devil's Due she plays the woman who appears on Ventax II claiming to be Ardra, the supernatural being to whom the Ventaxians supposedly sold their planet a thousand years before. She shifts shape, makes the ground shake and takes a fancy to Picard, appearing in his quarters uninvited.
Picard challenges her contract in an arbitration judged by Data, and the Enterprise-D crew find the cloaked ship that powers her tricks. DuBois plays her with relish, and the exposed fraud is led away still flirting.
