The Dog Was the Mastermind
aka: The Dog Is The Mastermind
The Man Behind the Man turned out to be about the least conspicuous person possible. The Hidden Villain was underneath your nose the whole time. The dog was the mastermind! Guess sometimes it is the person you least expect. You've seen him before. Maybe once, maybe a few times, maybe repeatedly throughout the story, but you never suspected a thing up until The Reveal. Sucker. The Butler Did It is the classic, Cliché example (which never really was a cliché.) Beware, however, in certain types of fiction, such as when you are supposed to guess the identity of the villain, this can come off as an enormously crappy twist ending. Or at least a really confusing one. Keep in mind that this is a Reveal Trope, so beware of spoilers!

Anime and Manga
- In Code Geass, no one could have possibly guessed that the co-Big Bad of the story was actually Anya, the fairly emotionless girl. Even less likely is anyone figuring out that the dear old Mommy everyone loves could be one of the biggest evil bitches in anime history.
- In Domu, the psychic menace terrorizing the apartment block turns out to be the mentally-deficient little old man.
- In Eden of the East, the mastermind behind the Selecao organization, Mr. Outside, is really an old taxi driver. You may remembering seeing him in the earlier episodes, long before his reveal near the end of the story.
- Fullmetal Alchemist. The Homunculus Pride is little Selim Bradley. The biggest clue to his identity are his speech patterns in the original Japanese, which wouldn't get through to an American reader. One translator did pick up on this and correctly predicted his identity.
- In an anime episode of Golgo 13, Duke Togo is hired to kill a British aristocrat running his own private intelligence agency, but misses a perfect opportunity when he steps out of his armored limousine. Togo instead kills his manservant, having realized that the aristocrat was just being hired as a front. The man who hired Togo is impressed that, even when given the wrong information, Golgo 13 always gets his target!
- Who is the Claw in GUN×SWORD? The old man talking to Wendy in the park.
- Used in Hayate the Combat Butler. Santa in Hayate's 'imaginations' from the first chapter is revealed to be Mikado. Although the reveal doesn't really unnerve Hayate, since he's already been unnerved by this point in the plot.
- In Higurashi: When They Cry, this is done so well that even if the Big Bad had a creepy moment or two, you wouldn't have known who it was until The Reveal. The Big Bad has been shown in every single arc, and, as far as the viewer was concerned, had no chance of being the villain. After all, it is extremely difficult to suspect a character that looked like she was promptly killed off every single arc. Even with the very few creepy moments before The Reveal, who would suspect that it was the dead nurse faking her death every time?
- Comedic example: The villains of the first arc of Jinrui wa Suitai Shimashita are the headless, skinless chickens that had appeared earlier but did not even show evidence of intelligence. This should tell you everything you need to know about the series.
- In LASBOSS X HERO the demon lord is the heroine, Nina. What.
- The lesser-known Lily C.A.T.. takes all of the tropes from the movie Alien and puts them in a blender. There's even a cat on board the ship, and a secret android working to bring back the murderous alien at the expense of the crew. The catch...is that the cat is the android.
- In the Medabots anime, the Big Bad turns out to be a (cybernetic) house cat using the body of a mad scientist as its puppet.
- Naruto: The mysterious leader of the Akatsuki ninja terrorists is neither Pain nor Orochimaru nor Madara, but the Plucky Comic Relief Tobi.
- In Rosario + Vampire, the leader of the terrorist organization Fairy Tale and most powerful character in the series is eventually revealed to be Miyabi Fujisaki, the guy who was almost married off to Mizore back at the start of Part II. This character was important when first introduced, but was never mentioned again afterwards, and certainly showed no signs of being Alucard himself.
- One story of Outlaw Star had the main characters seek out and eliminate the leader of a small-time gang operating out of an ice cream truck. The leader turned out to be the potted cactus with Mind Control powers.
- Hardly anyone could have expected Aji Tae, the Big Bad of Shin Angyo Onshi, Diabolical Mastermind who had already brought down a country before the series began and is stated to be an Evil Sorcerer of the highest order to be that Adorkable Pretty Boy healer with a pet goose who shows up to save one of the main characters and clearly plays into the role of not-so-covert sage mentor later. All exactly as planned by him. The fact that he completely changes his appearance between flashbacks and actual story helps to mislead readers.
- Shugo Chara! has one. Who was the Man Behind the Man? Hikaru Ichinomiya.
- In Steins;Gate, it turns out that the SERN spy is none other than Okarin's landlord, the completely un-suspicious Mr. Braun, who had never spoken a single line about anything plot-worthy until then.
- Tantei Gakuen Q has an epic "Whaaaat!?" moment when the high priest behind five murder cases in the Kamaikakushi village is revealed to be the cute and innocent Fuuma Mio, who later turns out to be a Anti-Villain thanks to More Than Mind Control that Broke the Cutie. Result? Eventual redemption and Tears of Remorse.
- Time Bokan series: "Zenderman". Oddly enough, it was the Trio's pet this turn around who turned out to be the Big Bad.
- In chapters 6-7 of Zodiac PI, Lili is behind someone who names itself "Sirius", thinking it's the one she already met in the past. In the first of those two chapters, a girl with huge glasses named Yukiji appears multiple times in the background, staring down Lili multiple times, and also briefly helps her in the latter chapter. At the end, after Lili discovered that the Sirius they were searching for was not the same one as the last time, Yukiji is shown briefly monologuing about that guy who called himself "Sirius"... then she takes off her glasses and a wig revealing she was the other Sirius all along, annoyed because someone stole her moniker and she wasn't the one who punished him for his evil deeds.
- In Mushoku Tensei the Big Bad has many potential agents, all of which Orsted has identified and tracked in the past save one. The single agent whose actions constantly foiled Orsted's plans while never drawing any attention was Gisu, a man with no combat power or political sway.
- Tokyo Ghoul pulls this off to an astounding degree. The One-Eyed King, the mysterious leader of Aogiri Tree, turns out to be Eto, the strange and childlike member of the organization always hanging around in the background. Then it takes it even further, revealing at the same time that she's also Sen Takatsuki, the oft-mentioned and Adorkable horror novelist.
- Astérix: The villain behind the sickle-trafficking gang in Asterix's second album, "Asterix and the Golden Sickle": He appeared time and again before the reveal? Check. Was he Beneath Suspicion? Check. Is it a surprise both to the heroes and the audience? Check. Does it make sense with the general theme of that album? You bet, because this is the only way the not so bright members of the sickle-trafficking gang could get away with an operation like this for so much time.
- In a two-part story in Detective Comics (circa 1989), Batman tries to stop the anti-establishment villain (or anti-hero depending on individual viewpoint) Anarky. Over the course of the two issues, the reader is shown scenes of a family man and his son, both together and apart. These scenes slowly imply that Anarky is the father, and he even tries to take responsibility when Batman catches him with Anarky's cape. Turns out he was just covering for his son, who was the real Anarky. The son was a middle schooler at the time.
- In the Darkwing Duck comic book series, a recurring villain is a genetically engineered house cat who fakes his own kidnapping from a research laboratory. Yes, in the Darkwing Duck universe ducks can keep cats as pets.
- In the Doom Patrol comic, the would-be cosmos-destroyers in the Cult of the Unwritten book are led by the Archons of Nurnheim—i.e. a couple of Punch and Judy puppets. Why, yes, as a matter of fact, this was written by Grant Morrison.
- This happens twice in 52. The first time is a huge early reveal that the time issues going on are the work of Skeets, Booster Gold's sidekick. Oh, and he kills Booster. In the very last issues after Booster is revealed to be alive due to time travel tricks, it's discovered that Skeets is possessed by Mister Mind. Said villain had only appeared in a few panels without ever saying a word in the early issues.
- In the third ever Justice Society of America story in All Star Comics #5, the JSA bust up a series of rackets headed by a mysterious figure known as Mr X. At the end of the story, an innocuous milquetoast who had appeared in each of the individual chapters turns up the police station. It turns out he is really Mr X and now, with all of his rackets smashed, he intends to turn himself in and live off the state in prison.
- Nick Fury, Agent of SHIELD, threw the readers a curve when the identity of HYDRA's leader, Don Antonio Caballero, proved to be an alias. Ripping off his life-like mask, the true Supreme Hydra stood revealed as Fury's long missing WW2 arch enemy Baron Wolfgang von Strucker. It was a moment so jarring, artist Jim Steranko made it a two page panel for the occasion.
- Rat-Man: One story has the eponymous "hero" meeting Graziello, a stick figure who annoys him by telling corny jokes and laughing in a monotonous way, and Rat-Man can't get rid of him. In the end we discover that everything that happened in the issue was Graziello's plan: as a failed comic book character who never got the chance to be published, he lured Rat-Man to the comic book school and in doing that he had appeared in a Rat-Man issue, thus finally being published and read by many people!
- In the original Silver Age Spider-Man comic book, The Big Man—a New York crimelord and leader of the Enforcers—was revealed to be Frederick Foswell, a browbeaten reporter at The Daily Bugle.
- This is something of a reoccurring theme among Spider-Man villains. The original Green Goblin was eventually revealed to be Norman Osborn, the father of his best friend (this being long before Norman established himself as the Lex Luthor of the Marvel Universe). The Jackal, better known as the villain who set up The Clone Saga, was Peter's nerdy science professor. The Hobgoblin, a villain modeled after the Green Goblin, had a two-for-one deal. He was originally revealed to be a Daily Bugle reporter and longtime minor supporting cast member Ned Leeds until a Retcon explained that he was yet another minor supporting character who had since faded into near-obscurity.
- One particularly jarring example involves Spider-Man searching for the murderer of a scientist who had created a crime cataloging supercomputer. The culprit is none of the three suspects, but the computer itself.
- A variation in Jonathan Hickman's Avengers comic book. The Starbrand has come to our Earth, and we're shown several scenes at a college focusing on different characters we believe are potential hosts. At the end of the issue, the Starbrand chooses an inconspicuous background character that had meaningless interactions with each of the candidates.
- Homaged in Bongo Comics' Radioactive Man series which generally parodied most of the major cliches in comics, superhero especially, and had the final issue reveal that Radioactive Man's deadliest foe was Radioactive Worm, an Expy of Mister Mind, who reveals it was caught in the same explosion that created RM. Indeed, as pointed out in a footnote, if you look back at the first issue's splash page of Claude caught in the atomic explosion, you can see a tiny earthworm crawling up from the ground right below him and being in it as well, thus planting the reveal as this rather than one of the Stranger Behind the Mask variety
- Similarly, in their short-lived Bartman comic, the true villain behind the crime wave that's taken siege of Springfield? Lenny, thanks to the fact that a faulty leak had dropped minor radioactive waste on his head resulting in him going temporarily insane, a moment that's briefly seen early on in the first chapter as a Funny Background Event while Mr. Burns and Smithers were talking.
- An Anti-Hero version of this trope happened in Watchmen. Rorschach's identity was mostly a secret until it is revealed he was that random homeless guy that was always hanging out in the background.
- In Batman Eternal, all of Batman's Rogues Gallery are brought together and manipulated by a mysterious hidden villain who seems to have learned Batman's identity. Each time Batman seems to be getting close to a big mastermind (Hush, Riddler, Owlman, even Ra's Al Ghul), it turns out that they were just invited by the real Big Bad. In the finale it's revealed that the villain was Cluemaster, a fairly minor member of Batman's rogues who rarely pulled off anything big. As it turns out, Cluemaster had gotten fed up with his constant fights with Batman and decided to apply himself to making a full-proof scheme to destroy him; to divert attention from himself he invited a bunch of big-name Gotham villains to the team-up to make Batman think the culprit had to be a huge and major enemy like the Joker. That way, Batman was focusing on the idea that the mastermind would be this ungodly powerful person and never stopped to think that any of the c-listers would be able to pull something like this off. The twist was ultimately subverted: The plan was indeed Cluemaster's, but far more likely and foreshadowed villain Lincoln March pulled a Hijacked by Ganon in order to serve as the story's final boss.
- The Harry Potter story Backward With Purpose involved Harry, Ginny, and Ron traveling back in time to fix a Bad Future. At the same time (relatively), someone else is also traveling from the future and tweaking things behind their backs. It is revealed to be Harry and Ginny's son Albus, who was never seen previously and had not yet even existed in any form or timeline from the main characters' (and audiences') perspective. Perhaps most bizarrely, if you read the sequel it all makes sense.
- In the Firefly fanfic Forward, it turns out that the mastermind behind the events of the "Charity" episode was Katie, the little girl following Zoe around, who was actually a powerful psychic.
- In the Legend of the Five Rings fanfic Rokugan 2000, the champion of the Realm of Evil turns out to be Hoshi Jack, the motivational speaker who stars in a cheesy TV talk show.
- A Harry Potter fanfic called The Ones You Never Expect starts off with Colin Creevey being revealed to have faked his death in the final battle. He then meets up with his brother to report to Dedalus Diggle. All three report to Crookshanks. Who reports to "The Queen": Hedwig. As it turns out: The war wasn't between Voldemort and Dumbledore; it was between Nagini and Fawkes. And Hedwig as been waiting on the sidelines, faking her death, until the two sides butchered each other so that she could take over the world in the aftermath.
- At the very end of The Unchosen One, it turns out that the mastermind for the whole operation—a plot including the near-destruction of Equestria, Twilight temporarily turning evil, and Trixie getting ascended into an alicorn, although the last one wasn't actually part of the plan—is actually Princess Cadence, with some help from her henchman Discord. The whole thing was done so she could get her hooves on the Element of Dominance in order to establish her control of Equestria. No, this character has had no bearing on the plot whatsoever up until this point.
- In the last part of Reality Is Fluid, the person who sabotaged an experiment on the USS Bajor turns out to be a random background character who only even appeared in three paragraphs in what seemed like a throwaway scene in the middle of part I.
Films — Animated
- The villain in Hoodwinked fits this to a T. Except instead of a dog it's a cute little bunny rabbit named Boingo. The fact that he keeps appearing in the stories may send up warning flags to the savvy viewer. Used again in the sequel, where Hansel and Gretel, the supposedly kidnapped and innocent kids, are behind everything.
- In Meet the Robinsons, the Big Bad turns out to be the bowler hat.
- The Adventures of the American Rabbit has the eponymous hero getting a big surprise when he tackles the Big Bad, only to have him suddenly deflate. It turns out that the human-like figure was a decoy and the pet vulture who is usually perched on him is the real villain all along.
- In Blood Work, the serial killer turns out to be the protagonist's drunkard fisherman friend from the same marina.
- In Cube 2: Hypercube, the supposed superhacker and mastermind Alex Trusk turns out to be... a blind girl?
- Dream House throws suspicion over nearly every character introduced. The actual killer? Someone who drove by the main character's house during one scene and did not become relevant again until The Reveal.
- In Galaxy of Terror, Kore, the unassuming cook, turned out to be The Planet Master who had sent the crew of the starship Quest to the planet Morganthus.
- An early cut of House of 1000 Corpses had the relatively harmless Grampa Hugo Firefly turn out to be Dr. Satan. Rob Zombie decided this would have been anti-climactic and changed it.
- The entirety of Identity's plot consists of a massive build up to who the murderer will be. Upon reaching the happy ending, it turns out it was the kid all along, and the viewer is treated to a hilarious montage that involves a grumpy looking kid walking away from an explosion and an obese maniac talking in a high voice.
- In the Hungarian film Kontroll, the masked killer is a welder who appears briefly in one scene. (Although that's not revealed in context; you can only find it out from behind-the-scenes information about the same actor playing both parts.)
- Played straight, and somewhat deconstructed, in the German Film "Net of Steel - The witness" (Stahlnetz - die Zeugin). The murderer is the eponymous witness, a 12-yr-old girl picked on mercilessly by her family and threatened by others because of their secrets. The deconstruction applies because the girl is not a "mastermind" - rather a desperate (but still aggressive) child - and before The Reveal she is seen just as a random girl who saw too much.
- Subverted in Phone Booth. At first, it looks as though the Caller was the pizza guy who only had a very brief appearance at the start of the film. However, it turned out the real Caller had the pizza guy hostage until he got caught, when he slashed his throat and left him as a decoy to escape. The real Caller only appears in person at the very end, when he reveals himself to Stu.
- The first Saw movie. The "dead man" in the middle of the room (John Kramer) is also seen in a flashback, where he's equally inconspicuous as a patient at the cancer ward. There is a hint, though. When someone starts loading the revolver the guy on the floor supposedly committed suicide with, it's empty. Revolvers don't eject spent cartridges. You can't kill yourself with an empty revolver...
- In Scary Movie, the Scream-esque serial killer is actually revealed to be the apparently retarded officer. Then again it is a parody.
- Scooby-Doo has a literal example, as it turns out that the mastermind is Scrappy-Doo, who, up until that point had only appeared in a short flashback.
- Debbie Salt, the seemingly harmless journalist reporting the murders, is the killer in Scream 2. And mother to the previous film's killer.
- Source Code: Major suspicion is cast on every person in the hero's immediate area (including The Hero himself!), and then in an interesting twist the Villain turns out to be a background character who at most appears for maybe about five seconds each time the protagonist goes back into the program, during which time he gets off the train when it stops- so he can plant phoney evidence of his death and detonate the bomb without killing himself in the process.
- In the Japanese film Suicide Club, the real culprit turned out to be the 14-year-old singers of the band named Dessert, who are often shown singing songs on the television at regular intervals but not actually playing any role in the plot—until The Reveal.
- In The Bone Collector, the killer is Richard, the technician from the beginning of the movie.
- All of the movies in The Thin Man series operated this way. Start with a murder, present a colorful parade of suspects, end by revealing the killer to be someone the audience had no reason to suspect
- Parodied in the "Scooby-Doo Ending" of Wayne's World, where it's revealed that Ben is really Old Man Withers, the amusement park owner who Wayne spoke to for five seconds near the beginning of the film..
- In White Noise, a random construction worker seen for all of three seconds earlier in the film turns out to be behind the kidnapping repeatedly mentioned in the background and in league with the evil spirits.
- Played double in Takeshi Kitano's Zatoichi, when the leader of the Yakuza is revealed to be the tavern keeper. Then it's revealed that even he was a decoy for the elderly busboy, who was the real power behind it all.
- In Friday the 13th Part V: A New Beginning, the copycat killer of Jason Voorhees turns out to be the paramedic, Roy Burns.
- Verbal Kint is Keyser Size in The Usual Suspects.
- The wolf in Red Riding Hood is Valerie's father, the village drunk Cesaire.
- The killer in I Robot is not a robot but VIKI, the AI that controls all the robots.
- The Bodyguard. Rachel's sister Nikki hired the hitman who's been hounding her the whole movie.
- The Hangover. The three friends find out their other friend was kidnapped by a gangster, who turned out to be the naked Asian guy that was in the trunk of the police car they stole the night before.
- The Harry Potter series has its own page for Chekhov's Gun and its various Sub-Tropes, so this comes up a few times. These became so expected that Rowling ended up adding a page to her website's FAQ where she asked readers not to assume that EVERY named character in the series had a world-exploding secret. In particular, fans had fixated on a random Muggle kid who appears at the beginning of book five, with many emailing Rowling and saying they had "figured out" that he was the true key to the entire storyline. In reality, he was just a random Muggle kid who was never seen again who Rowling had (accidentally) made a Red Herring by giving him the same surname as Harry's mother.
- One of the most famous examples from mystery fiction is Agatha Christie's The Murder of Roger Ackroyd. To put it simply, the narrator did it.
- In the second book of the Foundation trilogy it is revealed that the Mule is Magnifico the clown.
- In The Hitchhikers Guide To The Galaxy, the masterminds of Deep Thought's experiment were the lab mice that humans thought they were experimenting on.
- In the Star Wars Expanded Universe series New Jedi Order, an evil alien race called the Yuuzhan Vong invades. Their leader is Supreme Overlord Shimrra, a God-King who truly looks the part. The last novel in the series reveals that he is actually being force controlled by his jester, Onimi, a being so far below Shimrra that he was considered as little more than a pet.
- In the Star Trek New Frontier novel "Stone and Anvil", the Excalibur crew needs to find the man who created Janos' intelligence to help him extend it. To bad he doesn't exactly know how to do that...the real mastermind is his pet Gribble, a small animal no larger than a rat. Before the Gribble can do anything, though, Janos eats him.
- Charles Stross
- In Accelerando, everything that happened turns out to have been masterminded by the Macx family's robotic cat.
- The Big Bad in The Jennifer Morgue is evil media tycoon Billington, the Blofeld-alike, right? Nope, it's his white Persian cat, Fluffy. Okay, it's actually a Cthonian war god possessing Fluffy.
- Occurs in Zilpha Keatley Snyder's The Egypt Game—the murderer is not a suspect and is only mentioned once in passing.
- Quentin Makepeace, a foppish playwright in the Prime Minister's company, turns out to be the mastermind of all the events in The Bartimaeus Trilogy.
- In Murder In Pastiche, the killer turns out to be the ship's purser, who was a detective fiction fan and thought it would be a waste if there were so many famous detectives on board and they didn't have a murder to solve.
- In the first Norby book, Ing is Fussbudget 2 Gidlow.
- Sherlock Holmes
- In the story "Silver Blaze", the murderer was a horse.
- In the story "The Adventures of the Lion's Mane", the murderer was a lion's mane jellyfish.
- In the book version of The Bone Collector in the Lincoln Rhyme series, the main villain was the doctor, also seen only briefly at the beginning and end.
- This pattern is also repeated in other books of the Lincoln Rhyme series. The Coffin Dancer is pretending to be a hobo taken into custody as a witness and The Ghost is masquerading as one of his own victims, as a Chinese illegal immigrant.
- In Isaac Asimov's Lucky Star and the Moons of Jupiter, while there is a human villain, it turns out the real bad guy is a robot dog who served as a Seeing-Eye dog for a scientist. Subverted in that the dog was just the tool of the Big Bads, revealed by doing something he shouldn't be able to do. There's an early brief clue concerning his reaction to a Venusian Frog.note
- In Skulduggery Pleasant: The Faceless Ones, we find out early on that the elusive Batu is the man behind the Diablerie, but the mystery remains: Who is Batu? It was a mortal farmer who wanted to bring back the Faceless Ones as a means of getting his own magical powers.
- In Bridge of Birds, the true identity of the tyrannical Duke of Ch'in turns out to be the meek, perpetually-scared Key Rabbit. Oh, and his greedy peasant wife is a long-lost goddess. It actually makes perfect sense once Master Li explains it and there are many hints dropped throughout the novel, especially for the latter part, but it stunned many first-time readers.
- In The Dresden Files, this is Molly's reaction when she is shown a photograph of the traitor on the White Council in Turn Coat:
...huh. Who's that?
- In Doorways in the Sand, there's a near-literal example: the mastermind is in nearly every scene, disguised as the cat. Also, the being who was influencing Fred to steal the artifact in the first place was the artifact itself.
- In Harry Harrison's Star Smashers of the Galaxy Rangers, the race of Big Bads, who were mentioned throughout the book turn out to be tiny turtles with Psychic Powers kept as pets by another race.
- In William Tenn's 1955 short story The Servant Problem, the ruler of a future Dystopia is a Smug Snake subconsciously controlled by his education minister, an Out-Gambitted Magnificent Bastard subconsciously controlled by a Magnificent Bastard psychologist, who in turn was Out-Gambitted and controlled by a junior technician. Things go pear-shaped for this Man Behind The Man Behind The Man Behind The Man when it turns out that he, like everyone else in the world, was conditioned to worship the ruler; this dystopia is evidently now a dog chasing its own tail.
- In one of the Agaton Sax kids' detective books, someone who appears to be an average-looking member of the crew of crooks turns out to be the criminal mastermind boss himself.
- In Hush, Hush, it turns out that the person trying to murder Nora was Jules. Given how he was virtually nonexistent in the story, it was rather...jarring.
- In Gone Girl, the person behind Amy's disappearance is Amy herself.
- Pretty Little Liars does this a few times with the reveal of each A. The first A turned out to be Mona, one of the main characters' best friends who pretended to be an A victim herself. The second A was Alison—the real one. It's revealed that all along the girl they thought was Alison was actually Alison's twin sister, Courtney. The current and third A has yet to be revealed.
- Inverted in the Robert Cormier novel We All Fall Down. One of the two main POV characters is an eleven-year-old boy who calls himself The Avenger after killing a bully with his grandfather's gun and then killing his grandfather to cover it up. It turns out he actually committed the murders a couple of decades ago, and he is actually a seemingly insignificant middle-aged character who appeared briefly earlier in the novel. He's no mastermind, but rather a pitiful, profoundly mentally-ill man who regularly retreats into the delusion that he is still a child.
- The same idea was used by Kim Newman in Dracula Cha Cha Cha (aka Judgment of Tears). The book has some parallels to the James Bond series and the Bond character shoots the Blofeld character. However, Bond had misread the situation. The real villain was a vampire shapeshifter. He was the cat and the Blofeld character carrying him around was just one of his minions.
- Often done by Fred Vargas : in quite a few of her novels, the murderer is a very inconspicuous and/or sympathetic character. Ariane Lagarde, in This Night's Foul Work, Lawrence in Seeking Who He May Devour and Louis Nicolas Emeri in The Ghost Riders of Ordebec are notable examples. The latter gets extra points for being the cop initially tasked with the investigation of the Ordebec murders.
- In the Dale Brown novel A Time for Patriots, the Big Bad is actually Uncle Pennybags Judah Andorsen.
- In The Burglar in the Rye by Lawrence Block, Bernie Rhodenbarr has to find out who stole Gulliver Fairborn's letters and murdered Anthea Landau and Karen Kassenmeier so that he doesn't get sent to prison for the crimes. Karen, the second murder victim and absent owner of the hotel room in which Bernie hides from the police, was the thief with some help from the hotel clerk. Erica, Bernie's best friend's overly-controlling new girlfriend, is the murderer.
- In The X-Files novel Goblins, the invisible killer turns out to be the dispatch of the local police, whose role in the story up that point has been saying few words over the radio. She is recognized by her Catch Phrase.
- The Herman Melville story "Benito Cereno" concern's an American ship captain's encounter with an under-provisioned Spanish slave ship. The Spanish captain's account of his navigational troubles doesn't quite add up, and his erratic behavior leads the American to suspect that he is a tyrant or insane. At the same time, he seems too ill and weak to be able to enforce his will at all. The explanation turns out to be that the African slaves on the ship carried out a successful uprising, and are using the captain as their puppet to win the American's trust. The captain's "devoted" black manservant is actually the leader of the rebellion, and is following him everywhere in order to keep him in line.
- Smallville. In "Roulette", Oliver is put through a series of life and death games. Whoever designed it has a really sick sense of humor. It is Chloe Sullivan.
- Good guy version: In the Get Smart episode "The Mysterious Dr. T", it turned out the genius inventor Dr. T was a kid seen selling newspapers.
- Sherlock has already pulled it twice. In "A Study in Pink", the serial killer turns out to be a cabbie, seen earlier when Holmes and Watson chased down his cab because they thought the passenger might be the killer. In "The Great Game", Moriarty is revealed to be Molly's boyfriend Jim, who showed up briefly earlier in the episode. Though this last was guessable, considering "Jim" is a nickname for "James".
- The second example also incorporated a subversion—for a moment or two, before the real mastermind appeared, the audience is led to believe that Watson is Moriarty.
- Many made-for-TV cop shows have this, but it was especially noticeable in Murphy. The killer is the bloke who is in the background of scenes. If most of the suspects are interviewed in a club it's the barman—also expect him to be a long-lost relative of a victim or chief suspect.
- Mr. Yang in Psych is revealed as this through flashbacks when Shawn meets her at the end.
- In the Monk episode "Mr. Monk Makes the Playoffs", it is revealed that Monk met Bob Costas after helping him out with a matter of a cat salesman who sold demented cats. In particular, Monk proved that Costas's cat planned to kill him with a squeeze toy.
- An episode of Community has the study group trying to discover who among them stole Annie's pen. It turns out it was Troy's pet monkey living in the vents, who we hadn't seen since his only episode one season ago. The study group doesn't find this out until much later in the season, though. At the time, they all decide that the most logical explanation is that a ghost stole Annie's pen.
- In an episode of Pushing Daisies, the killer was, of all people, a pig. It was an accident, so the characters promptly adopt him as a pet.
- One episode of Bones has the killer turn out to be the father of a friend of the victim, who was seen once in the beginning of the episode and had no lines whatsoever.
- Quite literally applied in an episode of Married... with Children when the Bundys are arrested for harboring fugitive Steve Rhoades. They all accuse each other of ratting Steve out to the police, but the true mastermind was Buck, the Bundys' family dog.
- Star Trek: The Next Generation:
- In "Aquiel," where the crew finds out that a shape-shifting organism is behind the Mystery of the Week. Two people, a Klingon and the eponymous Aquiel, are suspected of being the monster, but it's really Aquiel's dog, which served as a minor comedic subplot during the episode.
- In "Future Imperect", Riker awakens sixteen years in the future with apparent amnesia. However, the details of his future life don't add up; when he question his surroundings, the Enterprise bridge reveals itself to be a holodeck, with the evil Romulans pulling Riker's strings. Seems plausible. Yet, even this reality doesn't jibe with what Riker knows to be true. The real mastermind is Riker's "son", who is present in both realities. The boy is actually an orphaned alien let behind on a desolate planet, with only a holodeck to amuse himself. When Riker came upon the cave, the boy was delighted to have a playmate and pieced together a false world from Riker's memories.
- In the Angel episode "Harm's Way," Harmony wakes up after a one-night stand to find the guy dead, and though she doesn't quite remember what happened, she eventually realizes that she was set up for the murder. It turns out the real killer was...some random other vampire chick named Tamika working at Wolfram and Hart, whom Harmony had bumped into earlier. Tamika was upset that Harmony was on "the fast track" just from knowing Angel and his friends before they took over the company, and framed her so that she could take her job.
- In The Sarah Jane Adventures: Mr. Smith is a supporting character who gives information on aliens that land on Earth. It turns out he's a Xylok (sentient crystal) who created the computer as a host—and the most important thing to a Xylok is their purpose. Mr. Smith's purpose is to destroy the Earth's crust to free his kind—they were trapped there after their ship crashed to Earth (wiping out the dinosaurs). Mr. Smith escaped in the eruption of Krakatoa.
- An unusual inversion in that it's from the POV of the dog. Merlin is Arthur's manservant, and thus while the audience sees everything he does, Arthur has no idea. So when all is revealed, it's probably going to be shocking to a lot of people that the king's clumsy, cowardly manservant has been behind everything (or at least aware it was going to happen).
- Particularly noticeable in the Series 4 finale, where Morgana takes over Camelot and Arthur loses his belief that he can be king. Merlin guides him to the Sword in the Stone, telling him that it belongs to the rightful king of Camelot (when in reality Merlin put it there specifically for him), thus restoring his faith. Then, when everyone falls asleep, he sneaks into Camelot and leaves a Voodoo Doll under Morgana's bed to disable her powers. So, while it seems to Arthur that he was destined to retake Camelot, Merlin controls the entire situation.
- In a third season episode of NCIS: Los Angeles, Sam and Callen gun down a group of arms dealers, including Callen shooting the leader's driver in the cheek when he made a run for it. In a later episode, "The Chameleon", the driver turned out to be the mastermind, and everyone else was just hired help for that one job. The team started calling him the Chameleon after this turned out to be his standard M.O.
- The head of the Dirty Cop organization "HR" in Person of Interest turned out to be a guy who was onscreen for all of five minutes: a mayoral candidate's campaign manager.
- The killer in the season 4 episode "Terra Incognita" was the hotel doorman.
- Subverted in the conclusion of the Carver arc in Nip/Tuck. As Ryan Murphy said, "It's always a horrible cheat when it's someone like a neighbor who you met once, and they're the killer."
- In The Prisoner, Number One turns out to be a previously un-hinted-at duplicate of the hero, Number Six. Some of the writers have also hinted that in some way, The Butler was behind everything.
- In Criminal Minds, the BAU are investigating the death of a child who was believed to have been killed by a captured pedophile. It turns out the pedophile was guilty of killing several children, but not the one they found. The real killer was the boy's older brother, who was a budding sociopath, and his parents were trying to cover it all up.
- In a third season episode of Lost Girl, one of the therapists at a psychiatrist office is believed to be influencing the patients to commit suicide by attempting to enact dangerous childhood dreams. The main suspects are a regression therapist who practices hypnosis and the receptionist, who is a type of Fae that feeds on despair. However, it turns out to be the regression therapist's pet cat, "Dr. Bob", who is actually a shapeshifting rakshasa.
- In Broadchurch, a boy is found dead and the main suspects are an old man with a sex-crime record, a technologically-savvy vicar who likes to volunteer at the school, and a woman who had hidden evidence from the police. In the end the killer is revealed to be Joe Miller, the husband of Detective Sergeant Ellie Miller who had been investigating the case.
- In True Detective, the primary culprit of the murders, and the "Green-Eared Spaghetti Monster" ends up being the caretaker on the lawnmower from Episode 3.
- New Tricks: In "Ghosts", the murderer in a 60 year old murder case turns out to be another resident of the nursing home where the wife of the victim now lives who Gerry interviewed once to gain information about the wife.
- Dollhouse has a brutal example of this when it is revealed in the last few episodes of the final season that the big bad head of the Rossum cooperation, who Echo has trying to remember all season, is trusted friend, mentor, and ultimate father figure Boyd. He had been our Audience Avatar and Echo's Big Good for pretty much the entire run of the show. The outcry of horror and betrayal from the fans was overwhelming, even for a Joss Whedon show.
- The largest distributor of crystal meth in the American Southwest in Breaking Bad was posing as the manager of a chicken restaurant.
- The Good Guys. The serial peeper turned out to be the guy with the glasses in Ruiz's yoga class.
- Once Upon a Time season 4. The Author turned out to be posing as a peddler who point Snow and Charming to the Apprentice.
- In one of the more infamous angles of the late 90's, The Undertaker, then leader of the Ministry of Darkness, had been terrorizing Vince McMahon and his family, going so far as to kidnap his daughter Stephanie and attempt to crucify her on a cross. During the angle, it is revealed that The Undertaker actually answers to a Higher Power, though nobody knows his/her true identity. After Stone Cold Steve Austin hits the ring to save Stephanie from being crucified on a segment of Raw, he is jumped by the Ministry and tied to the ropes as the Higher Power reveals his identity to him. Stone Cold is livid as the show goes off the air. The next week, the Higher Power is hilariously revealed to be Vince himself, who ridiculously concocted the plan to apparently get over on Austin. "IT'S ME AUSTIN! IT WAS ME ALL ALONG AUSTIN! YOU ALL BOUGHT IT!…." It's generally thought by fans that this was pulled off amazingly well. Vince's line "It's me, Austin!" and JR exclaiming "Aw, son of a bitch!" are still quoted by fans today. Despite all that, this storyline is looked at as being stupid because there was no real point for McMahon and his cohorts to go through all that trouble just to mess with Austin. It was a great moment until you think about what just happened. It is also generally known that Vince being the Higher Power was at least a Plan C. One of the original choices was Mick Foley, but he turned the angle down because he didn't want to turn heel with no foreshadowing and wasn't in good enough shape to wrestle an angle with Austin. It's widely believed that Don "The Jackyl" Callis was another choice, as he originally managed the Acolytes and stated that he would be controlling everything from behind the scenes. This was apparently dropped when Jackyl was released before the angle ended.
- Hornswoggle was the anonymous RAW GM - the same RAW GM who was sending messages via computer to then-heel-commentator Michael Cole to screw with the other wrestlers. Responses to this reveal were typically negative.
- Parodied in The Far Side when (what else?) a cow suddenly stands up in court and says, "All right, I confess! I did it! That's right! The cow! Ha ha! And I feel great!"
- Played with and subverted in Luann. In the arc where two of the teachers (acting as chaperones) ended up dancing with each other, and getting recorded by an anonymous student via cell phone and posted on the internet and getting in trouble with the principal, one of the teachers thinks Luann did it, while another felt it was more likely that Tiffany did it. The male teacher's reason was because of this trope, to which the female teacher pointed out that he would also qualify for that exact trope to prove that it shouldn't be used. It turns out Tiffany really did do it, after Luann tricked her into revealing to her deed by claiming credit as being between her and herself, although she ultimately wasn't able to reveal it after Tiffany recorded her changing and then used her old cell phone as a decoy in case Luann did attempt to tell her.
- Late in BIONICLE's run, one of the serials revealed that a Great Being was disguised as one of the characters we already knew. About a year after the serial went on a hiatus, it was revealed that that the Great Being was not only Velika - a Cloud Cuckoolander that frequently spoke in riddles - but also that he was the one that killed Karzahni and Tren Krom.
- In the game Art of Murder: FBI Confidential, the killer turned out to be Raches, a character briefly mentioned in a newspaper article and supposed dead. Although this is minorly subverted because Raches is- in fact- your boss, Leon Chaser. Actually pretty obvious when you compare the two names.
- In Portal 2's co-op campaign, the robots are sent to kill what turns out to be the bird from Chapter 6 of the single-player game.
- In this case its played both metaphorically and literally. In Deadly Premonition the happy go lucky Forrest Kaysen turns out to be the Red Seed Killer the whole time- and his faithful companion Willie? He INTRODUCED Kaysen to the Red Seeds. SWERY 65 confirmed Willie is Kaysen's "keeper" and was relaying orders from the Red Tree. If you take a closer look at the game map, it's intentionally shaped like him◊, part of a bigger background story SWERY left out of the game.
- In The Witch's House, the Bigger Bad turns out to be the savepoint cat, who was actually the demon Ellen summoned to claim her powers.
- The Dog ending from Silent Hill 2 is a literal example, although it's really a parody. Said dog (named Mira) makes cameos in future joke endings.
- After spending the short four hours playing through the 12 other ranked bosses in MadWorld, you find out Rank 1 and a major accomplice in Deathwatch is none other than the man who hilariously gives tutorials for the bloody minigames. The Black Baron gets extra points for being the most challenging and epic fight in the game.
- Sam & Max: The Devil's Playhouse: Beyond the Alley of the Dolls plays this to excellent effect; the true mastermind turns out to be the ventriloquist's dummy Max has been carrying around for half the episode.
- In the beginning of the series finale, The Narrator of the series so far shows you a wall of pictures showing characters from the series, and proclaims that "one of the characters you see before you will betray Sam and Max." This sounds like an unnecessarily leading Reveal, until it's shown that "one of the characters you see before you" includes The Narrator himself.
- As well as the Season 2 finale What's New, Beelzebub?, where it turns out that the Soda Poppers have taken over Hell itself and have masterminded the events of the season in an attempt to make Hell more efficient (even going so far as to kick out Satan).
- Subverted, though, in that Telltale thought they were playing this trope straight, because they thought the Poppers were quite popular little schlubs, when in fact much of the fandom considered them The Scrappy, and thus thought The Reveal that they were the villains behind the entire last season was only too appropriate.
- Subverted in MARDEK Chapter 3, as the mastermind is a major villain that everyone suspects, but he's disguised as a "dog", Clavis, an enigmatic but inconspicuous character. The persona was actually made up by the villain in order to talk some sense into Rohoph, who was sprinting towards becoming a Knight Templar hard and fast.
- In The Bastard Of Kosigan, the real mastermind behind the whole plot happens to be Alexandra de Velan, your childhood sweetheart, who also happens to appear to die near the end of the second module.
- Persona 4 practically runs on this trope, in keeping with its theme of not letting first impressions or outward appearances deceive you. All three of the major players in the kidnappings and murders can be frequently found around Inaba doing absolutely nothing out of the ordinary.
- The real kicker is that the true final boss, the one who set the events of the game into motion, turns out to be... the nameless, forgettable gas station attendant whom you met at the very beginning of the game, who turns out to be none other than the goddess Izanami in disguise. Made even better by the fact she didn't have a character portrait, which is a good indicator of a notable character, until AFTER the reveal.
- Tomator at the end of The Lost Vikings 2 turns out to be the Bratty Half-Pint that sometimes appeared in the middle of the levels to be annoying.
- The head of the evil organization, H.A.R.M., in No One Lives Forever turns out to be a recurring background character that shows up drunk in most levels as a Running Gag.
- The player is given one hint: he sputters an alarmed "Uh-oh!!" when interacted with on the space station. He reverts to his usual drunken behaviour afterwards. This can also be taken as quite the compliment as most everyone else has been doubting Archer's abilities the Big Bad responds to her appearance with Oh Crap!!
- In endings of Vampire: The Masquerade – Bloodlines where the Ankaran Sarcophagus is opened, the whole affair is revealed to be a massive practical joke orchestrated by Jack and the cab driver (who may or may not be Caine).
- In Heavenly Sword it's revealed that King Bohan's bird is actually The Raven Lord; a demonic warlord from the sword's backstory. The final battle is against a fused version of the two.
- In Taz: Wanted, TWEETY is the mastermind behind it all. This is especially mind-numbing when you consider that he's been your tutorial and hint provider for the ENTIRE GAME, including the final level.
- In Baten Kaitos: Eternal Wings and the Lost Ocean, it turns out the traitor is the one person everyone suspected least: Kalas, the player character.
- At the very end of BlazBlue: Continuum Shift, it is revealed that the Imperator of the NOL is Saya, who we thought was a Damsel in Distress all this time.
- Until the reveal from a Drama CD revealing that Saya was brought forth to Relius shortly after her kidnapping and Relius made a cryptic comment that she's going to be a vessel for something, meaning Imperator Saya, for all means, could be a Puppet King manipulated by Relius and Hazama, therefore the mastermind may have been both of them since the very beginning.
- In BlazBlue: Chrono Phantasma, this turns out to be triple subverted. In the end, Saya backstabbed them after their failures, and left them to their fates, claiming that they have played their parts, and seized Phantom for herself. But it was because the mastermind isn't exactly Saya herself, but the Goddess of Death Izanami who was possessing her. And it turns out that she is the aforementioned 'something' that Relius modified Saya as the vessel of. A Goddess of Death is no mere 'dog', my friend.
- One that's really only known in Japan is the culprit in the old mystery game The Portopia Serial Murder Case (although some may have heard about its Shout-Out in Haruhi-chan). The culprit is the one you'd least suspect, because not only is he your assistant, he's also (since the main character is an unseen Heroic Mime) the guy executing the player's commands and speaking for the main character. The revelation was so out of left field that the phrase "Yasu is the culprit" is something of a minor Japanese meme for this sort of trope.
- This meme gets used in Umineko: When They Cry, when we find out the culprit's 'real' name is Yasu.
- In Wild AR Ms 3, you'll occasionally notice a purple-haired little girl. She might just walk by for a second as you enter a town or dungeon, or show up standing near a plot-important character as he begins conspicuously talking to himself. She is the Big Bad Manipulative Bastard.
- In the open-world First-Person Shooter Boiling Point: Road to Hell, a patron in the bar at the beginning of the game turns out to be the game's Big Bad.
- Played with in the "Killerman" event in Illbleed. Midway through, you're asked to finger a suspect for the role of Killerman (if you're right, you win more money). Besides the proper suspects you've encountered, the choices for who may be the murderous Killerman includes... Killerman, and the player. The latter is explained that playing Illbleed drove you insane and made you go on a killing spree. (This being Illbleed, this is at least somewhat plausible.) As it so happens, Killerman is the correct answer. Turns out the ghosts of those who've died at the park possessed one of the Killerman suits and have started murdering the employees in order to get their revenge.
- In Ghost Trick, it turns out that the course of the entire game was orchestrated by an alternate future version of seemingly-irrelevant-to-the-overall-plot character and literal dog Missile — in the form of a desk lamp that has no apparent role after the tutorial for the vast majority of the game, at that — trying to prevent the death of Lynne and Kamila that would have happened if he had not convinced Sissel to interfere. In the original version of events, The Bad Guy Wins. What makes this particularly memorable is that at this point, everything is wrapped up in a neat little package; what other game waits until the end to justify the tutorial?
- Played very straight in Discworld Noir. The serial killer who has been ritually murdering the citizens of Ankh Morpork (including the main character Lewton) is revealed to be the god Anu-Anu. When his worshipers are all gathered in church praying to him, his power grows and he transforms into a large bestial monster... but the rest of the time, he's trapped in the form of a small dog, which Lewton sees outside the Guild of Tomb Evacuators shortly before he is killed.
- This might count as a subversion, though, since Anu-Anu himself is manipulated by some members of his cult.
- In Pokémon Colosseum the diabolical Evice is none other than the mayor of the town you saved at the very beginning. And he promised he'd help!
- In Pokémon XD: Gale of Darkness, Mr. Verich, the rich man who buys food for the sailors in Gateon Port and whose bodyguard helps you early on, is Greevil, the Grand Master of Cipher.
- In the first Laura Bow game, Lilian turns out to be the Big Bad. You would have easily suspected anybody else but especially Rudy since they all had motive. However; it turns out that the inheritance was after all a Red Herring and the real motive was a psychological disorder on Lillian's behalf, thinking everyone was getting in between her and the Colonel.
- In The Last Express, it turns out the thing that killed the main character's best friend, Tyler, was the very MacGuffin he was hiding: a gorgeous golden egg covered in gems. When a certain sequence is entered and a whistle is blown, it turns into a mechanical falcon that comes to life and kills everyone present.
- The first case of Ace Attorney Investigations 2 involves the attempted assassination of a visiting president. At the end, after you had apparently caught the culprit, it turns out to have been orchestrated by a clown at the local circus, and someone you had defended earlier in the game.
- In the last case of Justice For All, the true culprit is your very client, Matt Engarde. Yes, the dumb TV poster boy is actually a cold blooded coward who couldn't even do the dirty deed himself. In Apollo Justice, the mastermind who orchestrated Phoenix Wright's disbarment and two out of four murders in the game is your own boss, Kristoph Gavin. And finally, in Dual Destinies, the most dangerous person in the whole franchise, with an astounding score of two murders, three attempted murders, and three bombings, one of which occurred in a courtroom full of people, is none other than Bobby Fulbright. Bobby "In Justice We Trust" Fulbright, the goofy, overdramatic detective who helped you throughout the ENTIRE game.
- In the Stylistic Suck "movie" Dangeresque 3: The Criminal Projective, which is an episode of Strong Bad's Cool Game for Attractive People, after a plot involving Dangeresque's nemesis Perducci and Uzi Bazooka, the true identity of actually, impostor of Dangeresque Too, the Big Bad is Craig, a character played by The Cheat, who had been in multiple scenes, unnamed, and previously referred to with the in-game tooltips by "The Cheat" when everyone else was described using their characters' names in the tooltips.
- On the Homicide Desk in L.A. Noire, you are tasked with solving a string of murders, all seeming connected to the real-life Black Dahlia case. At the end, you discover the killer...Garret Mason, a bartender you had interviewed as an incidental witness in the first case, and had likely forgotten about by the third.
- However, Genre Savvy players can actually guess the murderer's identity once he tells you that he's a part-time bartender who fills in for other bartenders in most of LA's bars, something the Black Dahlia murderer would find rather useful to pick his victims. Furthermore, after the first case, all the other bartenders you meet mention a temp agency which makes the connection all the more obvious.
- DS Visual Novel Time Hollow posits the notion, in an optional extended ending, that Sox the cat was the being behind most if not all of the game's events, or at the least that he's a mightier being than he lets on.
- The World Ends with You : Okay, on the one hand, something was seriously wrong with Joshua. On the other hand, nobody really was expecting him to be the Composer.
- The Infocom Text Adventure game Bureaucracy (written by Douglas Adams of The Hitchhikers Guide To The Galaxy fame) eventually revealed that the bureaucratic troubles the player had to navigate through during the entire game were secretly masterminded by an annoying nerd character who kept appearing at random and nagging the player to buy useless junk (and asking female characters for dates).
- In the Metal Gear series, you don't find out who the founder of the Patriots really is until about halfway through Guns Of The Patriots. It's Major Zero, the Mission Control from the Snake Eater. It's particularly a shocking reveal, since the character in question had not been revealed to have undergone a Face-Heel Turn or have traits of a Well-Intentioned Extremist.
- In Hotline Miami, who is organizing hitmen in animal masks to murder the Russian mafia? It's the two janitors you see briefly in one of the first few missions in the game.
- In Blue Dragon, the mastermind and final boss behind it all turns out to be the friggin' blue frog thingy the bad guy carried around all the time.
- In Rayman Origins, it turns out the person behind the all mess is the magician who gave you advices in levels and collected your lums at the end of each one. Many players barely notice his appearance through the game leading to Shocking Swerve . This twist was a holdover back from a time in development when the game still had an actual story, namely that The Magician idolized Mr. Dark, the ever-mysterious Big Bad of the very first game, and the whole plan was an attempt to emulate him.
- Appears often in the Professor Layton series. Many seemingly innocuous, or at least well-meaning, characters, including Chelmey in "The Curious Village," Flora in "The Diabolical Box," Doland the butler in "The Last Specter," and Angela in "The Miracle Mask," are revealed to really be villains wearing infinitely clever (and impossibly detailed and well-fitting) costumes.
- It is especially prevalent in Professor Layton and the Unwound Future, which sees Dimitri Allen disguised as the bartender at the Thames Arms, and Clive disguised as Future Luke. The latter plays it particularly straight because Clive has been parading around, as Future Luke, with Layton and his friends for most of the game, and had deceived his partner-in-crime, Dimitri, into believing he was building a time machine, when in reality, he was creating an enormous robotic weapon with which he intended to destroy London.
- The inverse also occurs in Unwound Future, when Don Paolo disguises himself as Layton as part of a plan Layton devised to foil Dimitri's attempts to trap him at the top of the Towering Pagoda.
- In the indie game Pizza Delivery the real mastermind in the house was the doll.
- In the When Gravity Fails licensed game Circuit's Edge the mastermind behind what is going on turns out to be the guy running the carpet shop who had no earlier involvement in the plot and you do not even have to meet at all when pursuing leads.
- Just when you think Trails in the Sky has a simple story, Professor Alba reveals, among other things, that he's behind everything.
- In Fallout: New Vegas, the metaphorical dog is.... YOU! Well, if you take the Independent route. You usurp Mister House, you savage the Legion, and then the pièce de résistance, you reveal to General Oliver that you suckered the NCR as well. You're initially, and throughout the game, a courier. The three great factions vying for the Mojave essentially got suckered by their mailman.
- In Tsukihime, the person who started the chain of events leading to the Near Side routes and was primarily responsible for everything that happens on the Far Side routes turns out to be Kohaku, Akiha's maid
- Dangan Ronpa has a variation of this trope. The Super Highschool Level Fashion Gal Junko Enoshima is killed early on, but late in the game it's revealed she was The Dragon. The real Big Bad is... the actual Junko Enoshima, who was using her Backup Twin as a decoy.
- In RosenkreuzStilette, the person responsible for instigating RKS' rebellion against the Holy Empire turns out to be Iris Zeppelin, the biological daughter of Count Michael Zeppelin whom we all thought as just an average Damsel in Distress, who is also revealed to be a reincarnation of Rosenkreuz. In the sequel, ~Freudenstachel~, she also instigated the church's founding of the Schwarzkreuz and the witch-hunt of the Magi (with help from Eifer Skute).
- In Nine Hours, Nine Persons, Nine Doors, the true mastermind; the person that planned the Nonary Game, planned the kidnapping of you and the other 8 people, blew up two people, and put you through the hellish game of life & death, is the protagonist's childhood friend and love-interest, Akane/
- Virtue's Last Reward manages to top it's sister game "999", by having the mastermind behind everything be the MAIN CHARACTER HIMSELF.
- In Murdered: Soul Suspect, The little girl that the protagonist first meets in the spirit world, after he is murdered, is the mastermind behind everything. She is originally presented as a friendly ghost who gives the protagonist a few tips about navigating in the spirit world. Then you don't see her again until the reveal that she is a witch who has been possessing the body of strong men to murder other witches, including the protagonist when he was alive. Then she sets the men up to be murdered to cover her tracks. If the player takes time to find all the collectables in the game, they'll uncover the truth before the reveal.
- The Adventures of Dr. McNinja story has one such reveal in the story "There Is A Raptor In My Office". It turns out everything was engineered by the Fox News weatherman. Earlier in the story, he was all puffed up to do a story about three hurricanes in the Atlantic forming a Mickey Mouse shape only to be deflated by a lead in story about velociraptor riding banditos. The entire story sprung from his efforts to keep Dr. McNinja's latest adventure under the rug so that everyone will be interested in his story.
- In RPG World, after Galgarion disguises himself to infiltrate the heroes, we get an extremely elaborate Red Herring Mole in the form of Eikre. Galgarion's actual disguise? A flower that Eikre had bought and attempted to give to Cherry.
Eikre: "Galgarion is Cherry's butt?! This is gonna be the coolest boss fight ever!"
- One Electric Wonderland story detailed Trawn's attempts to report on the bombing of the Nettropolis Mall. Lululu helps her find the man she suspected of causing the explosion, but he turns out to be a decoy. Who really led the attack? The cat seen sitting on the suspect's table while Trawn searched his apartment for evidence. Anyone can take on any form in Cyberspace, after all.
- Homestuck has two key examples.
- Betty Crocker and Her Imperious Condescension. Both of them are little more than background references until it turns out that they're actually the same person and a major villain in Act 6.
- Everybody figured that Lil' Cal was at minimum extremely creepy. It was a bit of a shock when he's revealed to be Doc Scratch's "father" of sorts. Then it's revealed that Cal himself contains the soul of Caliborn, also known as Lord English - the primary antagonist of the entire story. ARquisprite and half of Gamzee Makara are also stuck inside his body.
- The Roommates special titled "Mystery" would be a pretty standard Fair Play Whodunnit, if the culprit wouldn't turn out to be (for everybody's surprise including the detective) a freaking Muppet. It was background color and didn't seem to have any life of its own (carried around by a puppeteer) until the reveal. It... she also gives a pretty awesome Motive Rant to explain why she did it (she was jealous of the Cult Classic status of some other muppets running around the comic).
- In Greek Ninja, the one behind the attacks at Ariadnio and the danger unlike any the world had ever faced before, turned out to be none other than a weak and bitter man from Sasha Hunter's past. Really really past life....
- The identity of the butcher in There Will Be Brawl turns out to be a duo: Ness and Lucas, who were seen briefly in an early episode. This was so effective that nobody in Wild Mass Guessing correctly guessed it. Word of God near-explicitly denied the possibility beforehand, claiming that Ness or Lucas wouldn't play a large part in the series, since child actors were too hard to work with. While not technically false, since they only appeared in those two scenes and had no speaking parts, this was a highly misleading statement that helped to divert suspicion from the culprit(s).
- In episode 86 of Bonus Stage it was revealed the second version of Evil was MALCOLM, a very minor character who only appeared in one episode prior and never showed any signs of being evil.
- It was originally going to be revealed to be someone else, but Matt Wilson got sick of doing the series and just ended the arc on an Ass Pull.
- Occasionally happens in Shadow Unit—due to the nature of the anomaly, the gamma could be anybody, including the sweet little old lady, the shy teenager, a member of the team...
- In OH GOD THE RAPTURE IS BURNING, Cockroach Jesus was meant to be a throwaway creature, the warmup to all the silly crazy creatures in the serial novel. However, by about Act III, it is discovered he is the Big Bad of the entire thing, and is the emissary to the universe-destroying Rapture.
- Used/Parodied by Linkara in a "previously" that had nothing to do with the comic.
Linkara: You! You're the secret manipulator behind everything! *pulls out a stuffed bear* BEARRRRRRRRRRRRRRRRRRR!
- The "DNA Evidence" arc of Homestar Runner. After being Arc Words in a number of otherwise unrelated shorts, we get a story about a vial of green DNA Evidence that keeps changing hands and getting stolen. Turns out that it was from Strong Sad, who doesn't want anyone to find out if he's part elephant.
- In Becoming Human, it turns out the killer is Mr. Roe, the mild-mannered teacher, helpful teacher who was the only character to never be a suspect. A second more minor example is the janitor, who spent a lot of time in the background before being believed to be an accomplice, but eventually turned out to be a Red Herring... or was he?
- The Twist Ending of this one-off My Little Pony: Friendship Is Magic fancomic.
- Phelous has some fun with trope while reviewing The Amityville Horror 4. Why? The big villain is a demon possessed lamp. No, really.
Lamp: NO ONE EVER SUSPECTS THE LAAAAMP!
- The genocide arc of Gaia Online's storyline started in 2010 with vampire assassin Zhivago taking out a hit on Johnny K. Gambino, then reporting back to someone. Since Zhivago's previous boss was Killed Off for Real in 2007, the forums were abuzz with speculation on who the new boss would be, with guesses ranging from a resurrected Vlad Von Helson to the de-powered demigods to Gambino himself. Finally, an update revealed Zhivago talking to his new boss... Don Luca Kuro, a side character from a half-canceled forum event the year before.
- Similarly, the main villain in Gaia's MMO game, zOMG!? Labtech X, a character who hadn't been heard from since his apparent death in 2005. Most of the players didn't know who that was, unless they'd been very thorough in reading the plot events and comics.
- Le Visiteur du Futur: When confronted to the Big Bad, who so far only had been shown in the shadow, the Visitor asks him who he might be, successively suggesting a future or past version of himself, a future version of Raph or even a future version of their idiotic henchmen. Turns out they were... a future version of two of Raph's friends who had only appeared briefly in the first episode of the season at this point.
- In one Global Guardians PBEM Universe story, the mastermind behind the assault on a bank was the ten-year old boy the bank robbers released as a "good faith" gesture to the police.
- The trope name comes from an episode of The Simpsons, where Homer produces a remake of Mr. Smith Goes to Washington in which the villain is replaced by a dog, made obvious (to Homer) because "the dog has shifty eyes". The exchange is below, courtesy of SNPP:
Mel Gibson: You want me to replace the villain with a dog? I mean nobody will know what's going on.
Homer: They will if you set up that the dog is evil. All you do is have to show him doing this. [lowers eyelids and glances around in shifty-eyed fashion] The people will suspect the dog.
Principal Skinner: It was the butterfly, I tell you! The butterfly!Chief Wiggum: He's crazy. Take him away, boys!Camera pans to Bart-reborn-as-a-butterfly holding an incredibly obvious and large gas tank, laughing maniacally.
- As a Brick Joke, a dog with shifty eyes appears at the end of the episode.
- The two-part episode "Who Shot Mr. Burns?". The culprit was Maggie.
- Funnily enough, there's a "shifty-eyed" moment that lets you know it: in Part 1, Mr. Burns asks the angry mob who's actually brave enough to stop him. Watch that scene and notice the one person who just keeps glaring without looking away.
- This twist ending gets a call-back a few seasons down the line, when a Mob gang that has come to punish Homer are all taken down with precise, non-life-threatening shots from an unseen sniper. Who shot Fat Tony? Who do you think?
- "Nobody suspects the butterfly..."
- The deer in the Adventure Time episode "No One Can Hear You".
- In the Batman: The Animated Series episode "Beware the Gray Ghost", the Hidden Villain Mad Bomber is The young toy collector that bought Simon Trent Gray Ghost memorabilia earlier in the episode.
Simon Trent: What did you find?
Batman: Fingerprints on the toy car. And they belong to you, Simon Trent.
Simon Trent: That's not possible.
Batman: Your prints are on this car. You had the only copy of the show. The Mad Bomber followed the show step by step.
Simon Trent: But I'm not the Mad Bomber, Batman. I'm not. I sold my Gray Ghost cars months ago to pay for my... No, it can't be him.
- In Ed, Edd n Eddy, one episode has the Eds track down someone who went to great lengths to frame them for various crimes. It ultimately turned out to be Jimmy, who was angry at Eddy for casually giving him a wedgie.
- One episode of The Fairly OddParents has Timmy accidentally wish for a crew of pirates led by a captain named Dirtbeard that begins to pillage the town. In the end its revealed that Dirtbeart is NOT the leader, his parrot is. Dirtbeard got a chicken bone stuck in his throat decades ago, and the parrot has been interpreting his unintelligible screeching wrong on purpose to lead the crew from behind the scenes
- In the Ten Little Murder Victims episode of Family Guy. James Woods invites the core cast, "Family, friends and neighbours" to his mansion during a storm and people start getting killed off one by one. Turns out its Diane Simmons; Tom Tucker wanted to replace her with a younger sexier co-star which would cost her her job so she started murdering people in order to frame him. Another twist, is that Lois is the only one who knew she did it, so she was going to kill Lois. But Stewie from the mansion roof kills her first, saying no-one kills Lois but him. The twist about this is that several seasons back he gave up trying to kill her and turned from the psychotic murdering child, into a giddy cheerful (possibly) homosexual, so it was unexpected to see Stewie acting like his old evil self.
- The climax of the movie, Into the Wild Green Yonder, involved Fry trying to figure out the identity of the Dark One, who was the only individual whose mind Fry wouldn't be able to read. After he's able to read the mind of seemingly everyone else there, he comes to the conclusion that he himself has to be the Dark One. He isn't. The Dark One is the leech that Leela saved at the beginning of the movie, and which has been attached to her neck more-or-less ever since.
- In "That Darn Katz!" Amy finds out the professor who failed her doctoral presentation was an elaborate marionette worked by his cat, who sabotaged her so he could steal her idea to use it to sacrifice Earth to save the cat home planet.
- An early Hey Arnold! episode has the Twelve Angry Men Plot, as Arnold tries to defend Eugene from the accusation of having pulled the school fire alarm. The evidence for his innocence piles up and eventually Curly, one of the other jurors, confesses. This was the first time the culprit had any sort of characterization, but sure enough s/he can be seen several times in the background when the crime was committed.
- Spoofed in an episode of Invader Zim: Zim is plotting in his lab, and we get several establishing shots of his surroundings, including an inexplicable cooked turkey with flies buzzing around it. A few minutes later is suddenly bursts open to reveal his robotic servant, GIR.
GIR: It was MEEEE! I was the turkey all along!
Zim: (Beat) I was wondering what that turkey was doing there.
- At the end of Johnny Bravo Goes to Bollywood, it turns out the mastermind behind the whole evil plot was Johnny's helper monkey Jeeves.
- The villain from the Justice League mini-arc taking place in a parody of Silver Age comics was actually the Jimmy Olson Expy that had only appeared a few times before that and had actually created the false reality with his mind.
- The Big Bad of ¡Mucha Lucha!'s movie is a random girl that appears at the beginning.
- The episode "MMMystery on the Friendship Express" of My Little Pony: Friendship Is Magic, which ends with the reveal of Everybody Did It, in a show about being truthful and unselfish. Any resemblance to a famous mystery novel is wholly intentional.
- The three-parter "Brainwashed" of Pinky and the Brain has several false leads behind the mastermind heading the plot to dumb down the world. Turns out it's the cat belonging to the scientist responsible for genetically modifying the eponymous mice.
- A throwaway scene in the third Robot Chicken Star Wars Special reveals that Jar-Jar engineered the events of both trilogies, as he was a powerful Sith Lord.
- Scooby-Doo! Mystery Incorporated uses this a fair bit - usually, of the named characters, the culprit is the one who seems secondary, is introduced completely outside the course of the mystery, and doesn't seem to have anything to do with it at all. The biggest examples are probably the Trickel's Triquids mascot from "Revenge of the Man Crab", who only appeared for 10 seconds, and the Minner brothers from "Battle of the Humongonauts", who didn't appear at all before the unmasking and were only mentioned in radio ads and one scene on a billboard.
- Appears in an episode of What's New, Scooby-Doo? that took place in Greece involving a series of centaur attacks. At the end of the episode, Velma explains all the evidence that suggested that the criminal was the archaeologist, then unmasks it to reveal... a woman that she doesn't know. The mastermind was the archaeologist's partner, who appeared in the teaser before the gang showed up. The trope is even lampshaded when Velma complains that this should not count as her being wrong because she'd never seen the woman before and begins to sulk.
- The A Pup Named Scooby-Doo episode "Chickenstein Lives" had the monster be an unidentified man, who was actually "Granny Sweetwater" without the wig and dress. And one-upped in "Wrestle Maniacs" where the monster was really an unidentified man, who was really "The Coolsville Comet", who looked different because he wrestled with a different mask on that made his face look completely different!
- Older Than They Think. In the original series episode "A Clue For Scooby Doo" no-one recognizes the unmasked monster at first, until Shaggy of all people puts a beard on him. The ghost of the dead Captain Cutler was actually... a very much alive Captain Cutler.
- In Camp Scare the culprit ended up being Deacon who was really Babyface Boretti and Velma actually said "I did not see that coming."
- Steven Universe has an In-Universe example: Steven and the Gems are watching a kung-fu movie, and the bad guy turns out to be the janitor. Pearl says it was obvious, since he had been in the background of every previous fight and was also on the DVD cover.
- South Park:
- In "About Last Night...", Kyle's toddler brother Ike was the key player in Obama and McCain's Ocean's Eleven-style heist.
- A variation occurs in the Mysterion Trilogy (Coon 2: Coon and Friends, Mysterion Rises, and Coon vs. Coon and Friends) when Kenny as Mysterion tries to find out the origin of his immortality, learning it has something to do with the Cult of C'tulu. When a Jor-El type man in a glowing ball appears to explain everything completely out of nowhere, it turns out he was actually talking to Bradley Biggle AKA Mintberry Crunch, a character introduced for these episodes, who learns he really is a super hero who combines the powers of mint and berry. Kenny never really learns the truth about himself and is as confused by the entire encounter as the audience.
- The Grim Adventures of Billy & Mandy
- The true mastermind behind the events of the second movie was a carton of chocolate milk. It Makes Sense in Context, sort of.
- An even stranger example occurs in one episode where Billy and Mandy are taken by a demonic circus troupe to be performers. The episode ends with an obvious spoof of Scooby-Doo-esque unmaskings when everyone is trying to figure out who was really the one behind the circus. The culprit is revealed to be disguised as many random characters, including Eris and Billy's mom, but it turns out that the real culprit was a common earthworm. It's only made even more screwy that everyone acts like this makes perfect sense, except Billy, who is, for once, understandably confused.
- In The Powerpuff Girls episode "Cat Man Do", the girls defeat a villain and adopt his Right-Hand Cat — only the cat was the real criminal, using hypnosis to make his "master" do his bidding.
- "Nahhh, it can't be you."
