When the heroes cannot directly challenge the villain or his mooks they disguise themselves as monsters or build something that's basically a tank with a threatening exterior. Usually relies on intimidation more than any actual weapons. When villains resort to this tactic, it's a "Scooby-Doo" Hoax.
Compare and contrast Monster Façade, which is a similarly terrifying act put on by a Gentle Giant or a Reluctant Monster, who would have the strength to actually harm their opponent but prefers not to. See also Weapon for Intimidation. Compare El Cid Ploy, where the nonexistent threat is the heroes' dead or absent leader.
- Disney Ducks Comic Universe:
- A repeatedly used plot element in lesser Donald Duck comics — a variant involves making some idol worshiped by primitive people appear to speak and tell them to stop roasting the heroes or whatever.
- The Life and Times of Scrooge McDuck from Don Rosa — the first chapter when Scrooge scares the Whiskerville away by making a fake ghost. They were so scared that, years later, all the Whiskervilles have white hair (their first appearance showed them black and brown haired, so it wasn't a family trait before that).
- One Sam & Max: Freelance Police story ("Monkeys Violating the Heavenly Temple") has Max about to be used as a sacrifice for a volcano cult. Sam tries this trope, covering himself in mud to ape the volcano god the cult worships. Not only are the cultists not fooled, they beat the stuffing out of Sam.
- Fables uses a psychological Anti-Hero version when a reporter discovers the Fables' (fairytale characters who are actually real) society, though with the belief that they're vampires. Ultimately they kidnap him and trick him into believing they are indeed vampires who have tasted his blood and will control him into committing suicide along with publishing pictures painting him as a child molester (staged with the help of a 300-year-old Pinocchio) should he ever release his discovery. The reporter gets scared out of his mind and complies, but is ultimately killed a few days later by one of the more evil fables acting on his own.
- One of the few books Red Sonja ever experienced in-universe was The Tales of Gravaha the Clever, where the heroine dresses a field of cornstalks as an army to intimidate a foe with terrible eyesight.
- Scooby-Doo! Team-Up: The Top Cat crossover features two realtors whose project threatens the local suburbs. Since what they're doing isn't illegal, no matter how despicable they are, Officer Dibble pulls the Bedsheet Ghost trick to get rid of them. It takes some time to convince them it's a real ghost since Top Cat had previously tried the trick to keep his illegal gambling operation a secret and dressing up as a ghost is the first thing they teach at realtor school and, when they're finally convinced, they flee not in fear of the ghost itself but of how unprofitable the land they want becomes because of it.
- Modesty Blaise fakes an alien visitation in "The Moonman" arc.
- This is the modus operandi of The Phantom. The natives of his home country think he's an immortal personification of justice and protection, when he's actually the great-great-great (and so on) grandson of the original Phantom, with a Charles Atlas Superpower. Stories generally climax with him using a Scarecrow Solution to convince criminals that he's immortal.
- An American Tail, the Giant Mouse of Minsk.
- The Land Before Time, the original, four of the dinosaur children cover themselves in tar and pile on top of each other to save Cera from a group of aggressive Pachycephalosaurus.
- A Bug's Life, the fake bird. The solution part is subverted because the villains see the trick, but it is for the better, because the ants finally find the courage to rebel against the grasshoppers and send them packing for good as a more permanent solution. Also, the scarecrow was still vital to this turn of events, because it helped them consider the possibility in the first place, that the grasshoppers are not unbeatable. And then it's subverted again when Hopper comes face-to-face with what looks like another fake bird, only to discover that it's quite real, and has hungry chicks to feed.
- In Pom Poko, the tanuki attempt to save their home from urban development by shapeshifting into ghosts and monsters and parading down the streets to scare the humans away. It backfires when the humans mistake it for a publicity stunt for an amusement park.

- Rolli Amazing Tales: When Rölli and the Forest Fairy discover Seesteinen and Lerkkanen littering and making noise in their forest, they disguise themselves as a giant in a Totem Pole Trench style and attempt to scare the humans away. It fails nearly immediately because the "giant" and its threats provided by Rölli confuse the humans more than scare them, and the quilt worn by the two heroes falls off. However, while Seesteinen and Lerkkanen chase the duo, they run into the Big Rölli who really scares them.
- In Star Wars, Obi-Wan first appears by scaring away some Sand People who were about to kill Luke.

- In Lady Ninja Kaede, Yumeama uses a ninja technique to pose as Koharu's ghost and scare a confession out of Kichiemon.
- Kehaar in Watership Down, albeit only halfway intentionally great coincidental timing on his, Bigwig's, and the weather's part make it appear to the Efrafans that the bird was summoned out of lightning by Bigwig.
- Another early example features in Edgar Allan Poe's The Narrative of Arthur Gordon Pym of Nantucket, when the protagonist dresses up as a dead sailor's ghost to scare mutineers into abandoning ship.
- Doctor Syn ("The Scarecrow") is a vicar with a Secret Identity. Dressing as a scarecrow definitely has the secondary benefit of being a bit scary.
- Galaxy of Fear has a book where a Jedi ghost repeatedly terrifies Tash to try and spook her away from a threat, because until near the book's end she is only vaguely aware of him and can't understand what he says. He can't actually do anything to her, but it seems like it for a while.
- The Little Golden Book The Lively Little Rabbit has the rabbits and an owl build a long dragon costume out of tree bark and leaves, with all of the rabbits underneath it and the owl's wings protruding. It's a surprisingly awesome-looking dragon. It succeeds in scaring away the mean old fox.
- The Cordwainer Smith story "Golden the Ship Was— Oh! Oh! Oh!".
- In "Imprint of Chaos", the first story in The Traveller in Black by John Brunner, the protagonists build a giant scarecrow-puppet-thing to scare off a god. (It wasn't a very smart god.)
- In one of the Babar books, Babar defeats the rhinoceros army by disguising the elephants as monsters, painting giant eyes on their backsides and putting bushy wigs on their backs.
- Romance of the Three Kingdoms sees Zhuge Liang combine this with Thanatos Gambit. After his death, he has the Shu army set up a wooden statue of him, and then luring Wei's army into the main camp. Upon arrival at Shu's base, Sima Yi then saw the statue, and panicked, thinking Zhuge Liang to still be alive, causing him to retreat.
Chinese proverb: A dead Zhuge scares away a living Sima.

Tom wants to tell the truth but his uncle agrees with the farmer and makes Tom and his brother claim they saw the ghost to ensure kids don't come to the mines.
- In the The Adventures of Superman episode "Great Caesar's Ghost!", Perry White starts seeing Caesar's ghost. This turns out to be a trick by a gang of crooks to ruin his credibility as a witness in an upcoming trial. Superman turns the trick around on the gangsters, disguising himself as another criminal who had been killed by the gang, causing them to give up in terror when their bullets apparently just go right through the "ghost".
- Doctor Who: In "The Girl Who Died", part one of the plan to defeat the Mire involves altering what they see through their video interface, so that a ship's figurehead becomes a terrifying sea serpent and so on. Part two involves taking a video of the proud warrior race cowering in fear from obvious puppets, and threatening to effectively upload it to Space YouTube to ruin their reputation.
- When Bo and Luke were mistakenly declared to have drowned on The Dukes of Hazzard they faked a haunting by coating the General Lee with glow-in-the-dark paint and having Cooter rig it to run by remote control, using it to intimidate Boss Hogg to prevent him from blaming them for a theft. Subverted in that Boss Hogg isn't fooled for more than a few moments, and immediately suspects Cooter's involvement.
- Serenity herself was used in such a fashion in a Firefly teaser.

So, Don Diego spreads the rumor of the ghost of a mad monk roaming the grounds by talking to the impressionable Sergeant García. Later that night, Zorro disguises as the ghost and scares all the soldiers into fleeing, leaving Monastario alone.
- In Scooby-Doo, though it's often the villain who does this to scare away the Damsel in Distress from a Real Estate claim, etc., the heroes often use this technique as well.
- Gabe/Toxic Terror from What's New, Scooby-Doo? is a good one. In fact, the next to final scene has Gabe, Shaggy, Scooby-Doo, and the camp kid disguise them as Toxic Terrors and sending Clyde packing.
- Velma Dinkley, the brains of Mystery Inc. itself, does this in Scooby-Doo! in Where's My Mummy?.
