- The titular zombies of Zombie Land Saga use... makeup. Granted, it's a lot of makeup, since they're blue-green rotting corpses with sunken red eyes covered in scars and bandages without it, but it's somehow wildly effective; they comment on their surprisingly good looks, they're able to perform without arousing suspicion even when one of their members falls apart on stage, and the cop who's shot at Sakura twice completely fails to recognize her face to face in the third episode.
- Many a Monster of the Week in Sailor Moon disguise themselves as a human until they transform to battle the Soldiers. More common in the earlier seasons (almost all the Youma do it).

- In Scary Gary, shape-shifter Sheila seems to use her shape-shifting powers mainly to look like various human women to increase her chances of getting a date.

- Our Friend Power 5:
- When the turtles want to fit in on Earth, they try to disguise themselves as humans. Unfortunately, the only human they saw up to that point was Dalgeun dressed like a jiangshi...

- In Who Framed Roger Rabbit, the Toon who really killed Marvin Acme turns out to be Judge Doom, who wears a rubber suit to disguise himself as a human. We never get to see what he really looks like — other than his ever-shifting red eyes, which he normally hides by fitting a pair of glass ones into the eyeholes of his rubber mask.
- In Toomorrow, the aliens walk among humans wearing skinsuits with Latex Perfection masks.
- Isaac Asimov's "Spell My Name with an S": The numerologist is actually an Energy Being trying to prove a bet. They created The Little Shop That Wasn't There Yesterday just to present the idea of Dr Zebatinsky changing his name to Dr Sebatinsky.
- The Murderbot Diaries: The titular Cyborg goes undercover as a human when it's freed from the company that created it. Since it was mass-produced as a Faceless Goon, this consists of a long-sleeved shirt to hide its Arm Cannons and data port, plus an Auto-Doc session to tweak its build just enough that it won't match the profile on computer sensors. However, it takes some coaching from a sentient spaceship before it's able to avoid Uncanny Valley.
- Sunshine: Vampires have an Undeathly Pallor and a powerful Uncanny Valley effect, but Constantine is somehow able to look like a normal human in front of The Men in Black. Since he can turn it on on cue and it makes him distinctly shorter, it appears to be a supernatural ability.

- Ice Fantasy: After Ka Suo and Shi have to leave the Ice Tribe in a hurry, they quickly realize that their white hair and blue eyes draw too much attention among the mortals. Consequently, both magically change their appearance to a more human one, with dark hair and brown eyes.
- Interview with the Vampire (2022): For reasons unknown, the vampire Armand pretends to be Rashid, the human personal assistant of Louis, whenever he's in Daniel's presence, even going through the trouble of putting on brown contact lenses to hide his orange vampire eyes and wearing gloves to conceal his vampire fingernails. He drops the disguise at the end of Season 1.
- 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 13 Ghosts of Scooby-Doo episode "Ship of Ghouls" had a ghost impersonate a human travel agent as well as a human ship captain named Captain Ferguson. For the former, he simply made his body more opaque. For the latter, he wore a lifelike mask.
- Roger of American Dad! always dresses up as a human in public to keep people from realizing he's an alien.
- Zim of Invader Zim, uses this when he arrives on earth. However, he only uses human-like eye coverings while he retains his green skin, which Dib Membrane is the only one who notices.
- Lilo & Stitch franchise:

- 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!"
