 One of the laws is a rule against harming or killing humans; this becomes an important plot point near the conclusion of the film when Robby refuses to kill the Id monster, recognizing the invisible creature to be an alter ego/extension of Dr. Morbius.Hollywood purposely, and misleadingly, depicts Robby in the film’s advertising posters as a terrifying adversarial creature carrying a seductively posed unconscious maiden (Altaira), but no such scene is in the film and the images do not reflect in any way Robby's benevolent and intelligent character.Robby only carries one person during the film, the Earth starship's Dr. Ostrow, when he is mortally wounded near the end of the film.
