Human Disguise

From gods to aliens to robots and beyond, there are always stories of non-humans disguising themselves as humans, maybe even ghosts pretending to be living versions of themselves.

Super Trope to Hugh Mann, a human disguise done badly. Sometimes accomplished using a Mobile-Suit Human. See Humanshifting for shapeshifters who are only able to change into humans from their natural form. They Look Like Us Now is when an enemy species figures out how to do this.

Examples:

Anime and Manga
  • Wolves in Wolf's Rain have learned to project illusions that make them appear as humans in order to survive extinction. Rare humans (like Quent Yaden) can see through the illusion under certain conditions, while others must come into direct physical contact with the wolf to do so.

Comic Books
  • Martian Manhunter is a shapeshifter who disguises himself as a human when not working with the Justice League, so that he may live on Earth among humans as one of them.
  • While Superman was raised under the name Clark Kent and is a Human Alien, as an adult he refrains from using his powers in noticeable ways in public while being Clark Kent, in order to be able to keep living quietly as Kent with a job and family separate from Superman.
  • Supergirl adopts a human name and identity after arriving on Earth, which she uses as her secret identity.
  • The MAD comic "National Gorilla Suit Day" is an Overly Long Gag about various people revealing that they are actually Killer Gorillas wearing human suits.

Film

Literature
  • In the Ukiah Oregon series, the aliens are actually The Virus, but they arrived on Earth in the bodies of aliens. The last remaining original invader (referred to as Hex), is a Not Quite Human alien who uses heavy clothes and similar to disguise his differences when necessary.

Live-Action TV
  • The Slitheen of Doctor Who kill humans and use their skin as a disguise.
  • Bajorans, Klingons, Romulans, Vulcans, (with a little bit of plastic surgery and perhaps a haircut) and Trill (bit of makeup to hide the spots) can do this in Star Trek.
  • The main characters from 3rd Rock from the Sun are Human Aliens that pose as a human family.
  • The Good Place: In order to secretly torture the four humans whom they live with, the demons give themselves human skins so the humans don't notice anything odd.

Web Comics
  • The many supernatural creatures living in Kellwood forest in Charby the Vampirate rarely bother with proper disguises beyond sunglasses when traveling into the nearby human city due to the super strength Perception Filter on the place. When Charby and Mye invite Yiska into town with them she insists they disguise themselves as human first although Mye points out that it's not really necessary.

Western Animation
  • Tiny Toon Adventures:
    • In the short, "The Year Book Star" (part of "Toon Physics"), Babs and Plucky compete against each other to see who can star in the most photos of the school yearbook, with the loser having to suffer the humiliation of the winner's choice. During the official count-off, the two appear to have tied, until it is revealed that a human boy wearing an orange hat appeared in the background of every photo either of them was in, causing him to win easily. The Boy in the Orange Hat then reveals himself to be Buster Bunny in a latex mask and suit, who entered the competition to teach Babs and Plucky not to compete to win a bet, but all this does is prompt Babs and Plucky to beat him up as the short irises out.
    • In the episode, "Thirteensomething", Babs wishes she could audition for the titular Show Within a Show, and Buster dares her to. Knowing that the casting office only hires humans, Babs disguises herself as a human and changes her name to "Babs Bunawalskioversmith". Unlike Buster's disguise in "The Year Book Star", Babs is able to pass for human simply by covering her ears. The fact that her face is covered in fur doesn't quite go unnoticed: "You really should get a wax, dear. You have a lot of facial hair!"
  • Roger of American Dad! always dresses up as a human in public to keep people from realizing he's an alien.
  • Jumba and Pleakley from Lilo & Stitch are two aliens living with Lilo Pelekai's family in Hawaii. Both of them wear some rather poor disguises (only just sets of human clothing — female in Pleakley's case) that somehow fool most people.
