Lora

"Lora" was supposedly a humanoid female whose appearance was once assumed by a Rigelian hypnoid, while the creature was being manipulated by Harcourt Mudd. In an effort to convince an audience on the planet Motherlode to buy love potion crystals from him, Harry Mudd was trying to persuade the crowd that having exposed Lora to the crystals had caused her to fall in love with him. Thus, "Lora" spoke affectionately to Mudd, claiming to have been lonely for him and pleading for him to return to his ship with her. After Spock fired a phaser at the illusory female, the hypnoid resumed its natural, reptilian form, losing the appearance of "Lora".
