Spoiler warning: Plot and/or ending details follow.
Stella Mudd was a female Human in the 23rd century and the daughter of arms dealer Barron Grimes. She was also Harry Mudd's shrewish wife he had fled from years before. He created an android in her image - with a cut-off switch so he could get the final word in at last. James T. Kirk deactivated the switch, leaving her to punish Mudd. (TOS episode & novelization: I, Mudd; DSC episode: "Magic to Make the Sanest Man Go Mad")
