human disguise

A human disguise (also human guise and sometimes human form) is a concept in fantasy, folklore, mythology, religion, literary tradition, iconography, and science fiction whereby non-human beings such as aliens, angels, demons, gods, monsters, robots, Satan, or shapeshifters are disguised to seem human. Stories have depicted the deception as a means used to blend in with people, and science fiction has used the dichotomy to raise questions about what it means to be human.
