Evil All Along

Go To

"So Zoe's a villain now, hmm? I've had bigger twists with my lemon in my rum and coke... with no lemon, but hell, let's just go with it."

A character that is thought to be one of the good guys turns out to have always been evil.

For example, the hero is searching for a very special treasure. Too bad he doesn't know his way around. He meets a very nice person who offers to help the hero find the treasure. But wait, wasn't the temple supposed to be toward the south? Then why are you walking north? And why won't his guide answer his questions? And oh drat, there's the Big Bad. That "guide" was his minion, and thus evil all along.


Also known as the "Dadolf Scmitler". If the movie is constantly trying to deceive the audience like this, it can be harder for the audience to get to know the villain.

Compare Big Bad Friend (the hero's friend turns out to be the main villain), The Mole (a member of the hero team is really a minion of the villain infiltrating the group), Bitch in Sheep's Clothing (a Nice Guy turns out to really be a Jerkass), The Dog Was the Mastermind (the true identity of the main antagonist is the least likely suspect), The Killer in Me (the main character turns out to be the killer), Treacherous Advisor (the hero's mentor turns out to be the bad guy), Broken Pedestal (someone finds that the hero they looked up to isn't nearly as heroic and noble as they thought they were), Love-Interest Traitor (the love interest turns out to be evil), and Bait the Dog (where a bad guy does something nice, but only so they can then do something vile). Contrast Good All Along, Big Bad Slippage and Subverted Suspicion Aesop.


See Hidden Evil for subtropes. Not to be confused with Face–Heel Turn, which is a legitimate good guy going evil. This is when the character was always bad and faking good, not a fall to the darkside.

As this trope often involves major Plot Twists, all spoilers are unmarked.

    Anime & Manga 
  • Attack on Titan: The series zigzags this all over the place due to its Grey-and-Gray Morality.
    • Annie Leonhart, Reiner Braun, and Bertolt Hoover are revealed to be enemy spies sent to infiltrate the military and responsible for much of the bloodshed during the first half of the series. Then things become more complicated, with the revelation that while they are enemies....they are also complex, emotionally-damaged Tyke Bombs who express remorse over their actions and don't seem to have any choice but to carry out their mission.
    • The Military Police Brigade are infamously corrupt, but turn out to have a special Branch that operates out of the Capitol. This branch is the Secret Police charged with protecting the Government Conspiracy, primarily through torturing and murdering such dangerous individuals as weapons inventors, Bold Explorers, curious miners, teachers that question official versions of history, and powerful officials' mistresses. When the Survey Corps gets a little too close to the truth, they launch an extermination campaign against them by framing them for murdering civilians, smearing their already-poor reputation through propaganda, destroying their hideouts, arresting any of them that can be found, and sending out specialized units to kill them on sight, leading to a large civil war.
  • Bleach:
    • Aizen was initially introduced as one of the nicer Captains of Soul Society, and even questions the higher-ups decision to execute Rukia. He turns out to be The Man Behind the Man who started the whole conflict to begin with.
    "The Aizen you knew...never even existed."
    • And Ginjou, who, with the help of his accomplice Tsukishima's ability, manages to make it seem as though he and Tsukishima are enemies (because courtesy of Tsukishima's power, he actually believes they're arch-enemies, enabling him to get close to Ichigo and use him in his plan until it involves Tsukishima using his power on him again, reverting him to normal.
  • Blue Dragon: Zola near the end of the series. Though it appears at first that it's just a simple Face–Heel Turn, the characters try to fool themselves into thinking that. Evidence in the last episodes proves otherwise.
  • Danganronpa 3: Chisa was forced into having a Face–Monster Turn after being brainwashed in Episode 9 of Side: Despair in which they never found a cure for her brainwashing and she secretly pretends to a Nice Girl so that nobody suspects her into a Remnant of Despair.
  • Digimon:
    • In Digimon Adventure 02, Ken was the evil Digimon emperor all along. This is made glaringly obvious from his first appearance onwards.
    • In his first official appearance in Digimon Savers, Akihiro Kurata claimed to want to help Data Squad and his old friend Commander Sampson. He showed his true colors soon enough.
  • Dragon Ball Super:
    • Freeza's apparent Good Counterpart Frost turns out to be the very same as Freeza, just less prideful and is a Villain with Good Publicity. While Frieza simply wiped out the populations of planets and sold them to the highest bidder, Frost instigates wars so he can be seen as a "hero" by stopping them and buys the ruined planets on the cheap so he can fix them and sell them for profit.
    • In Dragon Ball Z: Battle of Gods, Beerus seemed to be subject to Blue-and-Orange Morality due to his duties as God of Destruction being necessary, while in the anime, the Elder Kai outright states that Beerus' acts of destruction are pointless and petty. This is taken farther when the anime adds several scenes of him wiping out entire races just for being unable to fulfill his appetite. While initially that could be dismissed as him needing to destroy something, the Universe Survival arc reveals that the Gods of Destruction aren't just supposed to destroy planets randomly; they're supposed to destroy evil people. All along, Beerus has been abusing his power by choosing to destroy good or neutral people for kicks, while letting evil people like Frieza's family run rampant through the cosmos and do as they please. This is rubbed in further when the Grand Priest notes that Universe 7's mortal rating is the second-lowest, meaning Beerus is quite possibly the worst of the Gods of Destruction.
  • Elemental Gelade: Rasati and Lillia's guardian. He broadcasts it from a mile away, but Rasati doesn't seem to notice.
  • Future Diary: In Chapter 50, Akise claims that Yuno is the actual villain, and is planning to use Yukiteru to drive him to the brink of despair and kill him in order for her to become God. It seems that Akise was right and wrong at the same time. Yuno wants to kill him, but only so they can be together forever via an endless cycle of Peggy Sues. Maybe.
  • Hellsing: Walter, Hellsing's butler and soldier, is revealed to be working for the Millennium Nazis (only in the manga).
  • Naruto:
    • Kabuto Yakushi actually did manage to pull off the "helpful, harmless stranger" routine pretty well. From his personality, to his appearance there's very little to tip you off to his being a threat. He was trained from childhood specifically for this, having worked as a spy on behalf of the Hidden Leaf Village from within all of the other major ninja villages.
    • Shinnō of Naruto Shippuden the Movie: Bonds spent fifteen years posing as a kind doctor, Cool Old Guy, and even a Parental Substitute to Amaru when in reality he's a callous, heartless Jerkass who was secretly using the nearby villagers' negative emotions to gather dark chakra for the Zero-Tails. Not only that, but it's revealed that he himself taught Orochimaru several of his trademark reincarnation techniques.
    • Sasuke Uchiha is revealed to have been this near the end of the series. Promptly after Kaguya is sealed away, with Obito and Madara also defeated, he announced his plan to kill the Kages and seal away the Tailed Beasts, revealing that his supposed Heel–Face Turn was really just an Enemy Mine.
      • Somewhat diminished both by Sasuke having genuinely abandoned his original goals and changing sides (it's just that his new plans to do good come from the same fundamental difference in his and Naruto's personalities and he's still not on Naruto's side) and by this mainly being a surprise to the audience (and Sakura): Naruto wasn't that shocked and Sasuke had already made his future intentions known to a number of people present, none of whom said anything because they knew he'd fight it out with Naruto to decide which of their philosophies was superior and they'd given up on any long-term plan beyond "hope that gets settled this go-around".
  • One Piece:
    • Nami is a minor case of this: she was introduced as a thief who stole only from pirates, but after about three arcs of her being seen as a good person, the fact that she stole their ship and treasure still came as a surprise…but nowhere near as much of one as when she's revealed to be a member of another, much more ruthless pirate crew. What makes this a minor case is that while she had been planning on betraying them the whole time, by the time she finally did, she had already gone too far into Becoming the Mask, and clearly missed them. That's not the full story, of course…but it's enough for this trope.
    • Klahadore from the Syrup Village arc is introduced as a strict but good-natured butler to a sick and kind young rich girl. A short while later, it's revealed that he's Captain Kuro, a cruel and cunning pirate captain who had faked his death three years prior, and since then had been plotting to kill said rich girl and steal her fortune for a quiet retirement.
    • In the Jaya arc, Blackbeard encourages Luffy to continue to pursue his dreams after he is mocked by another pirate crew. This guy would go on to defeat Luffy's elder brother Ace and hand him over to the World Government. When his and Luffy's goals cross over in Impel Down, he gloats about this in his face, provoking a small fight.
    • In the Enies Lobby arc, it turns out that four of the main antagonists had been undercover as good guys for five years: the ventriloquist shipwright Rob Lucci, the flying shipwright Kaku, the dutiful secretary Kalifa, and the kindly bartender Blueno are all revealed to be government-sanctioned assassins.
    • From the Totto Land arc we have Pudding. Originally introduced as the White Sheep in Big Mom's family and Sanji's sweet, innocent fiancee. It later turns out that her entire personality is a lie and she's just as evil as her mother.
    • From Big Mom's backstory in the same arc, the beloved Mother Carmel is not as holy and innocent as she seems. The kindly nun is just a front for child trafficking orphans and selling them off to the World Government. Had a young Linlin not eaten her, she would have ended up a Marine or a bodyguard for the Celestial Dragons.
  • Panty & Stocking with Garterbelt: In the last minutes of the final episode, we find out that Stocking is actually a demon.
  • Pokémon:
  • Yu-Gi-Oh! ZEXAL: Good heavens, Shingetsu. At first, he called himself a "Barian Guardian", and though it was clear he was a native of the Barian World, he seemed to be a decent guy who opposed the evil plans of the others, befriending Yuma and offering to help him. As it turned out, this was cruel deception. His true identity was Vector, who was not only evil, but likely the most evil and sadistic member of the Barians (or any villain of the current series) to date. (To make this worse, it is very likely that he was actually subordinate to an even stronger Barian.)

    Asian Animation 
  • In Season 7 episode 29 of Happy Heroes, the Supermen meet a woman named Jenny who is willing to be their mother (the Supermen don't have an actual mother, and their father Doctor H. isn't even biologically related to them). She has her evil side unveiled later in the episode, when she calls Big M. saying she's gained the Supermen's trust. After seeing how much the Supermen genuinely care about her, however, Jenny does a Heel–Face Turn.

    Comic Books

  • Deadpool has Shiklah. Word of God, Gerry Duggan says he received complaints about how evil Shiklah sometimes acted to Deadpool, and how he was ruining their relationship. He states that he reminds people that Shiklah is a demon, and that she did try to kill Deadpool when she first met him -he was just spared by his Healing Factor. Editor Jordan White, via social media, also mentions that Shiklah has always been evil. He says Shiklah only seemed more sweet and innocent during The Gauntlet series because she was new to the modern world, thus more naive to how everything worked, thus she had an infant curiosity and excitement to things.
  • Every time Mystique seems like she is going through a Heel–Face Turn, it will end like this. In one alternate future her name becomes the equivalent of Judas. Somehow she's just that good at faking it that people who know her full history still get taken in when she pretends to be reformed.

Diana is rocked to discover that Barbara had a long record as a thief and con artist who'd been using Diana to get her hands on various rare items. The Cheetah spirit had been meant to protect a tribe but the inner darkness of Barbara turned it into a beast. Diana is stunned to realize Barbara was never her friend, never an innocent and (as Batman puts it), the Cheetah didn't corrupt her, Barbara corrupted the Cheetah.
  • In the first arc of Detective Comics (Rebirth) Jacob Kane (Batwoman's father) is revealed to be the leader of the Colony, the initial antagonists of the series. He had been planning for years for Kate to join the Colony one day, even adapting his expectations to her own independent vigilantism in the wake of her dismissal from the Army. Downplayed in that Jacob isn't portrayed as evil or even a villain, but a man blinded by his personal vendetta against terrorism who completely misread his own daughter's expectations and goals for her own life.
  • In one 2000 AD Space Western short story, a group of cowboys help protect some human townsfolk from alien raiders who's trying to kill them.

By the time the cowboys realizes the truth, the towns folks revealed their true forms and kills all of them.
  • Sentinel was revealed in Youngblood: Judgment Day to be the one who was responsible for the vast majority of heroes being so dark, violent, and borderline insane, having rewritten the world with Hermes' book to match his ideas of what superheroes were supposed to be like. To that end, he kills Riptide and frames Knightsabre to get the book back and resume his control.

  • Numerous Disney movies seem to be very fond of this trope, revealing that an (un)expected character was actually the Big Bad the whole time, to the point that this twist can become predictable after a while. Examples include:

    • In Blood Promise, Avery Lazar acted as a friend to Lissa and Adrian. Was revealed to be manipulating them for her own ends. She had no problem on driving Lissa to suicide.
  • Brandon Sanderson:
  • Warbreaker:
    • Played with, though not exactly subverted, as Denth the mercenary, who has been leading princess Vivenna in her quest to overthrow the government of T'Telir (under the pretense of following her orders), betrays her, murders her best friend, and tries to steal her Breath. She is surprised, but since he had been warning her the entire time that he could not be trusted, she felt kinda stupid, too. Best line: "Do you know what I hate most about being a mercenary, Princess? Fulfilling the stereotypes. Everyone assumes they can't trust you. The thing is, they really can't."
    • Bluefingers, the God King's benevolent, fatherly, somewhat timid chief scribe, is the Big Bad and Denth's employer. He's not terribly evil as Big Bads go- the book casts him as a Well-Intentioned Extremist and Word of God describes him as a good man who got carried away- but he's still the ultimate mastermind behind the threats facing the protagonists, and the kingdoms of Hallandren and Idris more generally.
    • InLiterature/ Skulduggery Pleasant/Last Stand of the Deadmen throughout the Skulduggery Pleasant series, Erskine Ravel was shown to be a reserved and trustworthy member of the Dead Men, enough that when the time came, he was given over the role of Grand Mage of Ireland and took it upon himself to ensure the safety of both the human and magic communities that threatened to reveal themselves to the world, well, until it was revealed that he was secretly a member of the Children of Spiders and his true desire was to have sorcerers take over the world. After [[killing Ghadtly Bespoke and Anton Shudder]] to attempt to complete his goal, he gets what’s coming to him [[by Darquesse giving him constant pain for almost every hour of the day for his troubles]] and [[is sacrificed to the Accelerator to prevent the world from being destroyed]]**
    • The Stormlight Archive:
      • King Taravangian is presented as a kindly, if somewhat scatterbrained, authority figure who is famous for sponsoring hospitals in his city-state. He's actually The Chessmaster behind at least one of the major conspiracies active in Roshar and his hospitals are a cover to allow him to study the prophetic statements people have sometimes started making immediately before death.
      • Sadeas is a lesser example. While he was always evil, he put on a good show of being a Well-Intentioned Extremist trying to protect the king and kingdom in his own way. Then he abandons his oldest friend and thousands of soldiers to die, all so he could be the king's sole adviser. In the second book, he admits to himself that he's going to kill the king himself when the time comes, all for his own personal power and bloodlust. Literal bloodlust, too—his primary motivation is that he only feels alive when killing people.
  • In the final chapter of the final book in the Sundered Lands series, it's revealed that Percy is in fact Grinder Prickleback, the hedgehog who unintentionally blew up the world and is hellbent on seeking all six crowns so he can Take Over the World. He wastes no time betraying Trundle and Esmeralda once his true intentions are revealed.
  • In The Dinosaur Lords, Bogardius and Violette are presented as two of several leaders of benevolent sect called the Garden and become good friends to Melodía, helping her cope. Only later are they revealed as having been working for Raguel - who seeks to wipe out most of human population in the world - all along, and while Bogardius has Heel Realization, Violette goes on to become a Mouth of Sauron for Raguel.
  • Starting with Windmills of the Gods, Sidney Sheldon became fond of this trope; between that and the ten novels that followed, seven of them involve at least one character who turns out to be this, serving as the Big Bad or the Big Bad's accomplice. The Doomsday Conspiracy and The Sky Is Falling have many characters who fall under this trope, though the former also has a Good All Along character to compensate. An eighth book, Tell Me Your Dreams, has the heroine turn out to have an alternate personality that's "stalking" her and gruesomely murdering men, making her a debatable case of this trope.

    Live-Action TV 
  • 24 has Nina Meyers in Day 1, Charles Logan in Day 5, and Tony Almeida (sort of, it kind of gets complicated) in Day 7, as well as Dana Walsh during Day 8.
    • Jack (somewhat) during his Rogue Agent period in Day 8 is debatable. He definitely undergoes a Face–Heel Turn during that point, though it's left unclear if he did so immediately after the double whammy of Renee's death and President Taylor's betrayal of him and his claims that he was just trying to expose the Russian conspiracy were outright lies, which if so would loosely follow this trope, or if he did genuinely mean to follow this out and only abandoned it for the notion of killing everyone involved after murdering Dana. There are some hints that lean toward the former, including a "I was perfectly fine settling with justice, but that was taken from me!," rant near the end of the series.
  • In Agents of S.H.I.E.L.D., Agent Garrett is revealed to be The Clairvoyant, and Agent Ward is The Dragon to him.
  • Arrow:
    • In Season Four, John Diggle's supposedly dead younger brother Andy is revealed to be still alive, and a member of the terrorist organization H.I.V.E. Worse, evidence slowly mounts that he was a villain long before he was "recruited" into H.I.V.E. His arc explores whether or not he was always evil and if he can be redeemed. He demonstrates he is truly evil by betraying the group, directly leading to Laurel's murder by Damien Darhk. He even taunts John about it and threatens to kill the rest of his family before being gunned down by his enraged brother.
    • In Season Five, seeming ally Adrian Chase, the best known Vigilante in the comics, is revealed to actually be Prometheus — and what's more, his real name is Simon Morrison, and his entire arc is a deranged gambit to destroy Oliver. Vigilante is revealed early in the next season to be an unrelated character.
  • Ash vs. Evil Dead: The end of season 1 reveals that Ruby Knowby, previously hinted to be a Jefe like Ash, is actually a Dark One, and the true Big Bad.
  • Invoked in an episode of Bewitched. A chimp Samantha turns human lands a spot in an ad campaign for cologne and makes an immediate impression on Larry Tate and his client. Samantha, however, intends to take him back to his owner and suggests that, in order to get fired, he show his true colors, which he does by biting one of the crew behind the project among other things.
  • Charmed (1998)'s Christy Jenkins is rescued from years of being locked in a cave by demons. It turns out she's now working with them to corrupt her sister, so they can kill the Halliwells.
  • Boyd Langdon in Dollhouse. Turns out he was secretly the Big Bad all along and running a ridiculously complex Evil Plan with Echo and co. at the center. And he seemed like such a nice guy. Although he wasn't completely evil. He was more of a Well-Intentioned Extremist in the end.
  • The Flash (2014):
    • While Harrison Wells in Season One is obviously shady from the start, it's slowly revealed that not only is he the Reverse-Flash, he's actually Eobard Thawne and merely stole the real Wells' identity after murdering him and his wife.
    • Similarly, in Season Two, "Jay Garrick" from Earth-2 turns out to actually be Hunter Zolomon, better known as Zoom, and to have been manipulating the heroes all along by stealing the identity of the real Jay Garrick from Earth-3.
    • The first few episodes of the third season introduce Julian, Barry's co-worker who he doesn't get along with, and Alchemy, a mysterious masked person who's been giving people the powers they had in Flashpoint for unknown reasons. Viewers quickly guessed that they were the same person, to the point where the end of the seventh episode was seen as a Captain Obvious Reveal. Subverted when it turns out Julian had no idea, as he was being possessed by Savitar, the real Big Bad.
  • Game of Thrones:
    • Ramsey Snow/Bolton is a particularly horrific example of this trope. He is introduced by seemingly rescuing Theon from being tortured, claiming that he was an Ironborn agent sent by his sister, and appears to be Theon's saving grace. However, this was all just part of a twisted game, and Ramsey soon reveals himself as possibly the most evil and sadistic character in the entire show, and tortures Theon himself to the point that he becomes an empty shell of a man.
    • Roose Bolton and Walder Frey were rather unpleasant all along, but the Red Wedding cements them as completely irredeemable bastards.
  • This and a few other related elements are the Reveal for season 1 of The Good Place. Michael, the seemingly benevolent architect of the heavenly neighbourhood, is actually a demon (although they don't like the term), and the neighbourhood is actually an Ironic Hell intended to force Eleanor, Chidi, Tahani and Jason to torment each other forever.
  • Haven had William, who at first seemed to be a kind, mysterious stranger who helps Audrey recover her memories and get back to her friends. Then he turns out to be a cruel, remorseless man who enjoys giving people out of control powers to cause untold destruction.
  • In Lost it turns out that Henry Gale was really the backstabbing, manipulative leader of the Others...
  • Once Upon a Time despite being a show where typically Rousseau Was Right and nearly every villain has a sympathetic origin still has a few examples:
    • Cruella's backstory is that she was locked in her attic by her abusive mother, who was also a Black Widow. It turns out Cruella herself was the one murdering her stepfathers, and that she's been wicked ever since she was a child.
    • Dr Jekyll and Mr Hyde appear in the sixth season, at first showing Jekyll as the good persona and Hyde as the evil one. But when the backstory comes around, we discover that Jekyll once murdered the woman he loved and framed Hyde for it.
  • The Outer Limits (1995): In "Corner of the Eye", a group of aliens who look like demons befriend a priest, heal his cancer, and grant him a Healing Hands ability. They claim to want to help humanity and ask the priest to vouch for them when they eventually reveal themselves as their appearance would frighten humans. Eventually, the priest's friend finds out that the aliens are just as evil as they look. Everything they did for the priest was just to get him to trust them so that they could use him as a pawn in their plans to slowly take over the world.
  • Raising Dion: Pat Rollins, who for the mayority of the series is presented as a lovable nerd, a Parental Substitute to Dion, and Dogged Nice Guy for Nicole, is eventually revealed to be The Crooked Man. He killed Dion's father and several other superpowered people.
  • Sleepy Hollow: Henry Parrish the Sin-Eater, the heroes' supposed ally, is revealed in the first season finale to actually be Jeremy Crane, Ichabod and Katrina's supposedly dead son, who agreed to serve Moloch as the Horseman of War in exchange for escaping being Buried Alive and the chance of revenge on his parents for abandoning him. Everything else he did up to that point in the series was to earn the heroes' trust so he could betray them at the opportune moment.
  • Star Trek: Discovery:
    • While he was hardly a paragon of virtue, Captain Gabriel Lorca eventually turns out to be native to the Mirror Universe, manipulating the events in order to get close to Burnham, to whom he's attracted to (he raised and then seduced Mirror!Burnham). His final goal is to use her and, possibly, the Discovery to stage a coup in the Terran Empire and become Emperor himself with Burnham at his side.
    • Lieutenant Ash Tyler turns out to be a Klingon Manchurian Agent named Voq, the same Voq, who was named as T'Kuvma's successor. He does get better, however, after the Voq personality is erased for good, leaving behind just Tyler with two sets of memories.
  • Supergirl (2015): The episode "O Brother, Where Art Thou?" reveals in its twist ending that Eve Teschmacher has been working for Lex Luthor since before actually being introduced on the show, acting as his spy.
  • Supernatural:
    • Ruby was the only demon who had so far actually helped the Winchesters, yet the season four finale showed us that she was working for Lucifer all along and she helped Sam specifically for him to kill Lilith, and so bring back Lucifer to the Earth.
    • In the episode "Repo Man". Back when they were hunting Lilith, Sam and Dean exorcised a demon out of a man named Jeffrey. Now in season seven, women were dying in the same way the demon killed them back then, so the brothers return to town. It turns out Jeffrey and the demon were working together and had a relationship.
    • In the finale of season eight, it turns out that the angel Metatron, who advised the brothers on the last trial to seal Hell and was guiding Castiel in another set of trials to seal off the now corrupt Heaven, was not as harmless as he appeared — he didn't warn the Winchesters that completing their trials would kill Sam, and the trials he was helping Castiel with were actually components of a spell to banish all angels from Heaven as petty revenge for being cast out himself.
    • The Season 4 finale reveals Zachariah was working to start the apocalypse. In fact most of the heavenly host is in on it, as they believe Utopia Justifies the Means.
    • The episode "Freaks and Geeks" has the reappearance of a hunter from an earlier episode named Victor, who is training a group of children to hunt after their families were killed by vampires in an attempt to ensure that the next generation of hunters doesn't have the problems of the current ones. It turns out that the monsters he was sending them after were actually scapegoats for murders that were committed by a single vampire had committed on his orders.
    • The Season 14 finale reveals that Lucifer and Amara were right all along — God/Chuck really is an utter sociopath who treats reality (especially the Winchesters' suffering) as his entertainment. When they realize this and refuse to keep following his script, he turns on them.
    • The first few episodes of Season 15 have the Winchesters being aided by a demon named Belphegor, who says he's just a Punch-Clock Villain who wants to help restore the stability of Hell after Chuck unleashed all its souls. In actuality, he's playing them in order to enact a plan where he can absorb all those spells and become a god.
  • Timeless: Lucy's mother Carol turns out to be a high-ranking Rittenhouse member. Also, Emma, who seemingly fled into the past and spent a decade hiding from Rittenhouse, is eventually revealed to be a Rittenhouse sleeper agent.
    • Played with via Timey-Wimey Ball when Wyatt suddenly finds out that his dead wife Jessica is now alive. He doesn't want to believe anything fishy, but she soon turns on the team and reveals herself to be Rittenhouse as well. However, the original Jessica he had known before joining the Time Team probably had nothing to do with Rittenhouse; it was only because Rittenhouse was targeting Wyatt that they went back in time and corrupted this alternate version of her in her childhood.
  • True Blood tends to do this a lot, especially with their Big Bad of the season. As it turned out, Rene Lenier was just hiding behind his nice exterior while being a bloodthirsty sexist murderer, and in a more extreme example, Maryann Forrester who turned out to be a freaking homicidal Maenad. Season three followed suit with the Faux Affably Evil King Russel Edgington who quickly turns into a genocidal maniac, and season four arguably averts it by giving its Big Bad Marnie a bit of a Face–Heel Turn. Or rather, it shows her Start of Darkness.
    • Played somewhat straight with Rev. Newlin (Jr.); although it was clear from the beginning on he was more than just another bigot, few viewers were expecting him to turn into a full-fledged villain who imprisons the protagonists and wants to burn another character to death. Given, no-one was expecting him to become a vampire!
  • Van Helsing (2016): Midway through the first season, it becomes apparent there's a Serial Killer hiding among the protagonist group of survivors. It's ultimately revealed to be Sam, the deaf man who previously appeared to be a harmless Gentle Giant.
  • Veronica Mars: It's revealed in the season two finale that Cassidy was the one who raped Veronica before the series began, and killed a bus full of his classmates in the season premiere. During the final confrontation he also blows up a plane with three people on board, does something abusive to Mac, and seems to enjoy tasing Veronica before trying to kill her.
  • Thomas Cromwell of Wolf Hall. During the first season, Cromwell is presented to the audience in a more heroic light than other works about him. He is shown as loyal, hardworking, caring, a good listener, and respectful even to his enemies. However, during the final episode, his corrupt nature that he's historically known for reveals itself, after he schemes to have Anna Boleyn beheaded. Lampshaded by King Henry VIII who calls him a viper.

  • Several times in Dickensian parody Bleak Expectations, the person helping Pip Bin with his latest scheme, such as the engineer who Pip employed to build a sewage system under London, is blatantly his evil nemesis Mr Gently Benevolent (in that case planning to dig out the capital, float it across the Channel with hot air balloons and sell it to the French).

    Video Games 
  • Ace Attorney as a series does this several times, particularly in its more recent games.
    • The first major example would be Matt Engarde, your client for the last case of Justice For All. The nature of the game conditioning you into expecting him to not be a villain really helps.
    • In Dual Destinies, you discover that the "Phantom", an international spy, ruthless assassin and bomber, is none other than Detective Bobby Fulbright, the cheerful detective who's been ever-present in the game since the second case. (Technically, the real "Bobby Fulbright" has been dead since before the game's timeline started, but The Phantom is the only one you've met in the game). One thing that makes Ace Attorney's presentation of The Reveal very unique is that it has you pick the person's name from a list late in the game after providing some final hints.
    • The Japanese-only Ace Attorney Investigations 2 reveals the lovable and frightened circus performer Sōta Sarushiro (known in the fan translation as Simon Keyes), whom you actually DEFEND from an overeager prosecutor in the second case, has been tricking all the other murderers in the game into killing off his old enemies in a complex revenge plot, and is even responsible for both an attempted, and later successful, presidential assassination.
  • Another Code: Ashley's father's old coworker was evil all along, having killed Ashley's mother and stuff.
  • Assassin's Creed:
    • In II, "Lost Archives" DLC reveals that Lucy had switched to the Templar's side before the first game's beginning. She even allowed Subject 16 to die from the bleeding effect when he discovered her betrayal. Everything she did throughout the games was a ploy she and Vidic devised to use Desmond to obtain the Apple of Eden. It would have worked too, if Juno hadn't programmed the Apple to force Desmond to kill Lucy. She's a particularly unusual example in that she gets killed before getting a chance to reveal her evil side.
    • At the end of III, Juno herself reveals her true nature. Even worse, Desmond has no choice but to do what she wants since the alternative would be letting civilization be destroyed again and having the whole Assassin vs. Templar war repeat itself.
  • Asura's Wrath: The true cause of most of the game's events is revealed to be the Golden Spider, AKA Chakravartin.
  • Baten Kaitos: Eternal Wings and the Lost Ocean does a very unusual form of this. You know Kalas, the main character? He's actually been working for The Man Behind the Man this whole time.
    • Origins does a more standard version: Quaestor Verus is far worse than Lord Baelheit could ever be...
  • Batman: Arkham Knight features a subplot in which Batman and Robin are trying to find a cure to an infection caused by the Joker's Titan-tainted blood, which mutates those infected into clones of the Joker, which Joker himself sent to hospitals before his death in Arkham City. One such infectee, Henry Adams, is apparently immune, and Batman believes him to be the key to a cure... but as it turns out, Henry had not only been faking his immunity, but had hacked the Batcomputer right under Batman's nose and alerted Harley Quinn to the existence of the other infected. The end result: there is no cure for the infection, and all of the infected end up killed by Henry. Including Henry, once he sees that Batman is also infected, as he believes Batman will make a much better replacement for Mr. J than himself.
  • BioShock: This is part of the main plot twist that occurs about 2/3rds of the way through the game. Turns out Atlas, your main ally and Mission Control, was criminal mastermind Frank Fontaine all along.
  • BlazBlue: Calamity Trigger: In her story mode, Noel is accompanied by a mild-mannered pacifist intelligence officer named "Hazama." If you've seen trailers for Continuum Shift, you'll recognize him as Terumi, the one behind the events of Calamity Trigger. What did he want from Noel? To Mind Rape her to take Nu-13's place as a living weapon of mass destruction.
  • Bomberman 64: Sirius presents himself as Bomberman's ally and aids him in reaching Altair's fortress and battling its guardians only so that he could steal back his Omni Cube from Altair and use its power to conquer the universe. When his plan succeeds, he thanks Bomberman by putting "Destroy Planet Bomber" first on his list of things to do.
  • Bookworm Adventures: Professor Codex reveals that he was the cloaked individual that kidnapped Cassandra and that he sent you on the long quest because every enemy you defeat is placed under his control. Then you fight him.
  • Bravely Default: Airy, of all people, turns out to have been manipulating you the entire time. There's even an alternate ending if you manage to figure it out before her plan is completed. Not that it's all that difficult; the subtitle on the game's title screen even slowly morphs from "Where the Fairy Flies" to "Airy Lies" as the game progresses, just to make sure you get the message.
  • Child of Light: Norah turns out to be one of the Big Bad's lackeys. The worst part is she's your character's sister, and while their other sister is bad news, Norah was far better at hiding it. This is really annoying because she's one of your best tactical options experts, and you don't get her back until the New Game+ (she has to be killed as a boss).
  • Dead Island: Colonel Ryder White, the Mission Control that leads you through most of the game, turns out to be secretly evil (although this actually doesn't come as much of a surprise to most of the characters, due to their strong anti-authority attitude). He betrays your group near the end, steals the experimental cure for the zombie virus, and ends up being the final boss of the game. This is complicated even further in the single-player DLC where you actually play as Ryder White, and it's revealed he was never the Mission Control at all, and it was really Kevin (another supposed ally) who was impersonating Ryder the whole time over the radio, and who manipulated Ryder and the original 4 heroes into fighting each other.
  • Dead or Alive Dimensions: Genra is revealed to be a manipulative and power-hungry man, willing to do anything to get revenge for playing second-fiddle to the main branch of the clan, and that his loyalty and honor are just a facade to hide it. On top of it all, DOATEC didn't kidnap him and turn him into Omega; he went right to them and let them do so.
  • Dead Rising 2: Off the Record: In the alternate timeline, it's revealed that Stacey was the Big Bad all along. As soon as the reveal occurs her personality jumps straight from Girl Next Door to a cruel and sadistic Baroness.
  • Dead Space: A regular part of the series: Kendra in Dead Space, Diana and Marker-Nicole in Dead Space 2, Tyler in Dead Space Mobile, and Colonel Bartlett in Dead Space 2: Severed are all revealed to be secretly evil bastards after spending a large amount of time as your primary ally/Mission Control.
  • Diablo: The Witch of Tristram, Adria, was one of your biggest allies in the original game, and come the third game, after her rescue from Belial's Dark Coven, she sends you on a quest to obtain the Black Soulstone and outlines a plan to capture the last two Great Evils, Belial and Azmodan, in it so that she can shatter it and end them, and the rest of the Great Evils, forever. Only it turns out that not only does Adria have a far darker agenda, she was on the side of evil from the very start — after killing her own father and co-leading the Dark Coven with Maghda, she was drawn to Tristram by the dark power of the Lord of Terror, and not only pledged herself to his service, but had a kid with him by way of the possessed Aidan. She would use this kid, a bright young girl by the name of Leah, to bring about the rebirth of her master as the embodiment of all seven Evils in one being, the Prime Evil, in the cruelest betrayal of the entire series.
  • Your first quest in Act 4 of Diablo II is to deliver a Mercy Kill to Izual, a Fallen Angel who Tyrael tells you was a victim of Being Tortured Makes You Evil. When you kill him, he reveals that the Evil Plan you've been spending the whole game undoing was his idea in the first place, suggesting his betrayal runs deeper than Tyrael ever realized.
  • Die Reise ins All: One of many characters from literature appearing here is Sherlock Holmes]While he appears as nice as usual at first, it's later revealed that he was Moriarty in disguise] Counts also as Adaptational Villainy.
  • Dragon Age: Inquisition: The ending reveals that ally Solas was the one responsible for the rift breach in the first place, by giving the Big Bad the means to start his uprising. Solas only helped the Inquisition so that he can gain possession of the Orb and continue his plans unnoticed.
  • Drawn to Life: The Next Chapter: In the Nintendo DS version, you get a new Raposa to join the gang, named Sock. You find him in a town where he doesn't live, and he goes with you to find his real home. Well, you're supposed to believe that. Near the end of the game Sock asks for a valuable item, gets it from Jowee, and throws it away. He then appears to be Wilfre all along. It also goes for Mari a bit, although she just thought she would help everyone by it (she worked with Wilfre).
  • Eternal Darkness: At the start of Lindsey's chapter, a friendly patron by the name of Paul Augustine leads him to the Cambodian temple where Mantorok is entombed. Then it turns out that Augustine was actually Pious using an illusion spell.
  • The Far Cry franchise has a character like this in nearly every game, usually someone who started as the player character's friend or ally.
    • The first game has Harland Doyle, the very guy you're trying to rescue from the Big Bad. He still wants the rescue, but only because he's stolen the main villain's research and plans to sell it for his own benefit. Changed up in the console version, where the character is completely rewritten.
    • Instincts has Kade, who was working with the rebels the whole time.
    • Far Cry 2 has both of the warlords engaged in the civil war]], especially after you learn the nominal Big Bad isn't actually that bad.
    • Citra, Dennis and probably all the Rakyat by association in Far Cry 3. Despite serving as Jason's ally against the pirates throughout the game, they don't plan to let him leave the island.
    • Sabal and Amita in Far Cry 4 become, or maybe just reveal themselves to be, increasingly ruthless the further you go, until you start to wonder if Pagan Min isn't that bad after all.
  • Final Fantasy Adventure: The mysterious wizard who occasionally helps you out is eventually revealed as Julius, who's been using you the entire time to get his hands on the girl and her Mana Pendant. Retconned out in the Sword of Mana remake.
  • Fire Emblem: The Sacred Stones:
    • Everyone knows Prince Lyon is being devoured by the demon king, but that doesn't stop the main characters from believing he's still good. He's an interesting case where he actually invokes this trope to get Ephraim motivated to kill him so that he could die before the Demon King brings about the end of the world. He claims that all of their time they spent together as children he was pumping the siblings for information for the invasion of their kingdom just to make Ephraim angry enough to actually kill him, though it does not work as Ephraim and Eirika still believe in Lyon's inherent goodness. Even as they slay him.
    • Orson appears to be evil all along too, but unlike Lyon, the players can actually play him as a character. Later he appears as a boss and it turns out he used to be sincerely good, but after his beloved wife's death he became a huge case of Love Makes You Evil.
  • Jak II: Renegade: Near the end of the game, Kor is revealed to be none other than the Metal Head leader, the Greater-Scope Villain who had been attempting to destroy Haven City.
  • Kingdom Hearts:
    • Kingdom Hearts I: Ansem, the researcher who was studying The Heartless whose reports the player has been running all across the worlds to find. Turns out, he's the Big Bad and The Man Behind the Man. And both directly and indirectly responsible for everything that's been going wrong in the worlds for the past ten years or so! In a subversion, it turns out that the guy we were calling "Ansem" was actually the Heartless of the guy who stole Ansem's name. The real Ansem is more of an Anti-Hero.
    • Xemnas in Kingdom Hearts II presented himself as a Tragic Villain, someone made into a heartless monster who only wanted to regain his ability to experience emotion again for himself and his followers. Kingdom Hearts Dream Drop Distance puts the lie to that statement, revealing he lied to his fellow Nobodies, intentionally preventing them from naturally growing new hearts for themselves in the name of making them vessels to become extensions of Xehanort's own will. Kingdom Hearts III splits the difference a bit: Xemnas felt guilt for doing so and genuinely misses his deceased Nobodies and laments it in his final moments.
  • Kirby:
    • Marx from Kirby Super Star & Ultra. At first he seems to be an innocent jester creature who just wants the Sun and Moon to stop fighting, and tells Kirby to find Nova. He then later reveals that he really wanted Nova awakened so he could wish for world domination.
    • Magolor from Kirby's Return to Dream Land is another example. He asked Kirby and his friends for help repairing his ship and then defeating an evil dragon called Landia, but it ultimately turns out that Landia wasn't evil at all, and Magolor lied to the heroes so he could get his hands on the Master Crown that Landia was guarding and use its power for... yep, world domination. Thankfully, he reformed as of Kirby's Dream Collection: Special Edition, unlike Marx.
  • Knights of the Old Republic: It turns out that YOU, THE PLAYER are Darth Revan, former Big Bad of the setting, but didn't know it thanks to Laser-Guided Amnesia from the Jedi Council, leading to an Inverse of Criminal Amnesiac if you decide to return to The Dark Side.
    • Of course, you can fully defy this by playing as a Light side Jedi.
  • Legacy of Kain: In the original Blood Omen, Moebius the Time-Streamer is depicted as having simply been afflicted by Nupraptor's insanity like the rest of the Circle of Nine. As revealed in Soul Reaver 2, he was a devious Chessmaster and Manipulative Bastard long before then.
  • Mario & Luigi: Partners in Time: In the part where Princess Peach gets a purple mushroom on her face — it's not Peach. It was Princess Shroob the whole time, trying to take over the future castle.
    • And her big sister does even better - most people won't trust a random NPC who shows up out of nowhere with no foreshadowing whatsoever - but put on a familiar costume (Star Spirit) and they'll trust you just fine.
  • Mass Effect 3: Maya Brooks, the goofy, jovial, friendly Alliance Staff Analyst from the Citadel DLC, as it turns out, was an ex-Cerberus officer who left the group out of disgust because the Illusive Man had started looking to non-humans for help. She also was the one who orchestrated the mercenary ambush in the Wards to intercept Shepard's Spectre code and the one who killed Khan. She was working with Shepard's clone in an attempt to steal Shepard's identity, and, after leading Shepard and their party into a trap, leaves them to suffocate to death in an iridium vault. At the end of the DLC, she shows that she doesn't even have any loyalty to Shepard's clone, as she leaves them to their death as well. She at first appears to be one of the nicest characters in the series, but ends up being one of its most heinous.
  • Massmouth 2: The QBot. When first encountered, he offers to be your guide on the strange planet you've crashed on. As it turns out, the oddly numerous accidents and threats that befall you on the way are not coincidental, as he was working for the Big Bad the entire time and deliberately led you into danger.
  • Medievil: In the proposed and cancelled third game Medievil 3: Fate's Arrow, the plot kicks off from the ending of Medievil 2 and it turns out Kiya somehow became aware of Zarok and was all along manipulating Dan into taking her back to Gallowmere's time. Using the Anubis Stone she would raise an army of undead and join forces with Zarok to change the outcome of the battle of Gallowmere and ensure their victory to take over the world and enslave mankind forever.
  • Mortal Kombat 11: Sindel's backstory has always presented her as the queen of Edenia and mother of Princess Kitana, and forced to become Shao Kahn's wife after her husband Jerrod was killed following Shao Kahn's conquest of the realm and merger with his own Outworld. She eventually committed suicide in grief, but was resurrected in Earthrealm as part of Shao Kahn's plan to invade it and brainwashed to serve him until she was freed and joined the heroes. In the DLC story mode Aftermath, Shang Tsung convinces the good guys to resurrect her precisely because her heroic, non-brainwashed personality will help ensure their success against Kronika. What she does instead is join with Shao Kahn and, between them, help Shang Tsung basically wreck everything the good guys have been trying to accomplish for their own ambitions while proclaiming genuine love for one another. As this happens it's revealed that her death was not a suicide, but murder by sorcerer Quan Chi; she was not forced to marry Shao Kahn but did so of her own will, much preferring how he would flaunt his power and privilege in true Evil Overlord fashion to Jerrod's being a ruler for and of the people. Consequently, Jerrod was killed not by Shao Kahn, but by Sindel herself.
  • Murdered: Soul Suspect: Abigail is introduced as a possible friendly spirit that gives Ronan some tips on how to function in the spirit world. She is actually the Big Bad that is responsible for his death, and the deaths of all the teen girls in the game and throughout Salem's history. She possessed different police officers, including Ronan to carry out the murders in the game. Afterwards she killed them off. In the past, during the Salem witch trials, Abigail was one of the main people accusing others of being witches until she was caught lying and executed. Why? Because she has a personal vendetta against witches, even suspected ones. The Stinger? She's a witch herself.
  • OFF: The Batter intended to destroy the world all along.
  • Paladin's Quest:
    • The student who goes with you to the forbidden tower on the academy grounds and goads you into accidentally freeing Dal Gren at the very beginning of the game is revealed at the end of it to be the Big Bad Evil Overlord Zaygos in disguise.
    • A much more shocking example is Gabnid, legendary hero and founder of the Wizarding School where the game started. Unlike the rest of the Power Trio of Sufficiently Advanced Aliens, who wanted to help the population of Lennus, Gabnid's goal was always to rule over them as a god.
  • In Persona 3, Shuji Ikutski is introduced as a Nice Guy with a questionable sense of humor who often serves as the Mission Control and is set up to be the Big Good of the game. He's actually a part of the Big Bad Ensemble who manipulates the main cast to trigger the apocalypse so that he can "cleanse" humanity and Take Over the World. Though at least his sense of humor was genuine.
  • Persona 4:
    • Firstly, Detective Adachi, the true culprit who murdered the first two victims, framed a copycat killer and was indirectly responsible for the rest of the incidents by manipulating Namatame into kidnapping potential victims and throwing them into the Midnight Channel.
    • Secondly, the True Ending has the gas station attendant from the very start of the game, who is actually the deity Izanami and the mastermind behind the entire plot. Though she's less evil and more of a Well-Intentioned Extremist with Blue-and-Orange Morality.
  • Persona 5 has you mainly battling people who encompass Villain with Good Publicity, as they're all in positions of authority, and due to a combination of societal corruption and their own guile, maintain a positive public image. Some of such villains, such as Suguru Kamoshida, Masayoshi Shido, and most of the Mementos targets, are clearly shown to be despicable from the outset despite having their reputations protect them. However, there are some villains who do a better job of maintaining a friendly facade before being exposed, such as Ichiryusai Madarame and the traitor, Goro Akechi, who presented himself as a Sympathetic Inspector Antagonist before being revealed to be a Serial Killer furthering a devious agenda. The real kicker, however, comes with the True Final Boss, Yaldabaoth, who imprisoned Igor and impersonated him throughout the entire game, pretending to be the Big Good and your guide while being the very embodiment of the authoritarianism you're fighting against.
  • Pokémon
    • In Pokémon Colosseum, the mayor of Phenac City is actually the head of Cipher. In Pokémon XD: Gale of Darkness, the same goes for Mr. Verich, who is actually named Greevil.
    • In Pokémon Ranger an old man you help, named Gordor, is actually the head if the Go-Rock squad. In Pokémon Ranger: Shadows of Almia, a teacher in the ranger school, Mr. Kincaid, actually works for an evil organisation Team Dim Sun. Also, the Altru corporation and their leader Blake Hall are evil, and you don't know that till the end of the game.
    • Dusknoir from Pokémon Mystery Dungeon 2. In the Explorers of Sky remake, you learn that he's extremely skilled at pulling this off.
    • In the main series, there's Colress in Black and White 2 and Lysandre in X and Y.
    • Most of the Aether Foundation in Pokémon Sun and Moon end up being this, with their leader trying to summon fearsome alternate universe creatures to this world to destroy it, though the series later suggests that they were at least partially under the influence of UB-01, thus making the exact amount of 'evil all along' questionable.
  • Professor Layton: In the first two games, the antagonist Don Paolo disguises himself as other people. He's disguised as Inspector Chelmey in The Curious Village and as Flora in The Diabolical Box, though the real Flora does appear earlier in the game. Jean Descole does the same thing in the prequels.
  • Ratchet & Clank:
  • While the true nature of Dutch van der Linde's Sanity Slippage in Red Dead Redemption II is left open to interpretation, this is one of the conflicting opinions of the members of his gang In-Universe. Arthur and John believe that he was this but managed to keep in under control/hidden for a long time while Charles and Sadie think he truly changed. Notably by the time, the first game takes place twelve years later John believes the latter theory (though it's unclear if that's actually a Nostalgia Filter or just comes from them having built the narrative of his downfall backward).
  • Rhythm Thief & the Emperor's Treasure: Jean-Francois. Made worse by him being Marie's guardian in the first place, conspiring against her with Napoleon.
  • Sam & Max: Freelance Police: The Soda Poppers want revenge in season 2 of the game series.
  • The Secret World: during Issue #7, players are introduced to a sexy Russian super-spy apparently acting as the Council of Venice's representative in the field; though she's a little dead-set on you doing all the work, she's still helpful enough to blow up the Orochi forces at the dam for you, and she seems a little bit much of a pastiche of Bond girls to really be threatening... right up until the Russian stabs you in the back with a syringe. Turns out she's not a Council agent at all, and was only tagging along so you could help her find Emma. And the real name of the agent? Lilith.
  • Shounen Kininden Tsumuji: The Big Bad is revealed to be Fubuki who first appeared as a helpful person, however halfway through the story he orders Tsumuji and Chijimi to stop their journey, as soon they encounter him once the shadow tower appears his true self is revealed.
  • Silent Hill 2: Maria. To add insult to injury, you spend a lot of her "good guy" time trying to keep her alive.
  • Sly Cooper:
    • Neyla in Sly 2: Band of Thieves. During the first three chapters, she's quite friendly to the Cooper Gang and helps them deal with Dimitri and Rajan using a Loophole Abuse, only to betray Sly and Murray to Interpol when given the opportunity. The final chapter reveals she's actually working for the Klaww Gang, and is further revealed to be the actual Big Bad when she merges with Clockwerk and kills the Decoy Antagonist Arpeggio.
    • Sly Cooper: Thieves in Time reveals Penelope to be the Sly Cooper franchise's version of Prince Hans, in that she faked being in love with Bentley in order to get him to design weapons, profit from terrorist organizations, and Take Over the World, while also planning to kill off Sly and Murray out of jealousy. Whether she's always been a heartless scumbag or became one during the Time Skip is intentionally left ambiguous, but one line after her defeat implies the former.
  • Splatterhouse: In the original series, the third game revealed that the Terror Mask had ultimately planned to conquer Hell, and was using Rick to destroy those demons that were in its way. The entire series amounted to its Batman Gambit.
  • Tales of Monkey Island: LeChuck From the moment that Guybrush Threepwood inadvertently turns him into a human who acts like a Harmless Villain and helps out on Guybrush and Elaine from Chapter 2 up to Chapter 4 (all the while wearing his charming belt buckle), then kills Guybrush in a clever ambush as soon as our hero cures everyone of the Pox of LeChuck; Elaine sees that "with or without all that voodoo, [LeChuck is] still nothing but an evil sack of scumm".
  • Tekken: In the original game, Kazuya appears to be The Hero, planning to defeat Heihachi in the tournament and take over the Mishima Zaibatsu. By the time 2 rolls around, he's revealed his true colors and, now in charge of the Zaibatsu, proves to be far more openly brutal and evil than Heihachi ever was.
  • The Legend of Zelda: A Link Between Worlds: Princess of Lorule Hilda sends Link to rescue the seven sages of Hyrule who have been captured by their common enemy, the wizard Yuga. After Link saves all of them and gets the Triforce of Courage, Hilda reveals that she and Yuga have been working together to steal the Triforce in order to restore the fallen kingdom of Lorule to its former glory but doing so by dooming the kingdom of Hyrule. This is downplayed when Yuga betrays Hilda and reveals that he never intended to save Lorule, but rather remake the country in his own image, bringing further destruction. After Link defeats Yuga, Hilda rears for a Last Stand against Link, but Ravio comes just in time to make Hilda realize her actions.
  • There are oh so many in the Trails Series
    • Trails in the Sky has Colonel Alan Richard, an army colonel and disciple of Estelle's father who turns out to be the Big Bad of the first game, Professor Alba, an archaeologist who turns our to be a high ranking figure in the Secret Society Ouroboros, and Renne, a little girl who turns out to be an Enforcer in Ouroboros.
    • The Crossbell duology has Joachim Gunter, a doctor at the local hospital who turns out to be the head of the DG Cult, Dieter Crois, the banker-turned-mayor of Crossbell who is the descendant of a clan of alchemists, his daughter Mariabell Crois, Arios Mac Laine, a bracer who wants revenge for the death of his wife and blinding of his daughter, and Ian Grimwood, a lawyer who similarly wants revenge for the death of his family.
    • Trails of Cold Steel has Vita Clotilde, a famous songstress who turns out to be another higher up in Ouroboros, and Crow, a party member and fellow Thors student who turns out to be C, leader of a terrorist organization.
  • The Scooby-Doo video game Scooby-Doo, Who's Watching Who? has a character named Mace Middlemost, who is the producer of the reality show ''Ghost Scene Investigation. At first, he seems harmless, but in the end he turns out to be the true identity of the Ghost Hunter Haunter, having menaced the Ghost Scene Investigation team while disguised as a ghost for the purpose of boosting ratings in an unethical manner.
  • Super Robot Wars Z: Rengoku-hen introduces several new allied characters note . Without exception, EVERY SINGLE ONE of them turns out to be a bad guy by the end of the game, though admittedly Kravia's case is "brainwashed heroine".
  • Xenoblade:
    • Shortly after Big Bad Egil is revealed to be something of a Well-Intentioned Extremist, albeit consumed by vengeance, Dickson—Shulk's surrogate father and Dunban's best friend—is revealed to be one of the Co-Dragons of Zanza. Better example with Zanza himself, the source of Shulk's visions, his power, his life even, who had been guiding the party from the start and helping them against Egil with countless Deus Ex Machinas, is really a Manipulative Bastard who did all of that just so that he could return to power and then harvest all life on Bionis to preserve his immortality.
    • Alvis is something of a subversion. He was also one of the Co-Dragons, but when it gets right down to it, he was never really capable of resisting, being no more than a computer programmed to follow the orders of his users.
  • Yoku's Island Express: Kickback, your helper who had been assisting you throughout the game, is in fact the evil God Slayer. It's possible after defeating him to find and forgive him, in which case he'll being helping you again.
  • Ys Seven: This game plays around with a lot of JRPG tropes. One of the major plot twists is that the Big Bad of the game is actually, of all people, Tia, the flower girl who you meet early on and who seemingly takes the role of potential main love interest. Unlike, say Luna or Lufia, Tia was secretly evil from the start instead of being forced into a Face–Heel Turn midway through the game.

  • Red vs. Blue:
    • Felix is revealed to be this after spending Season 11 and the first half of Season 12 pretending to be a good guy. When he betrays the others, he goes on an angry rant declaring that pretending to be a good guy and the heroes' friend was sickening, and now they will suffer and die for forcing him to go through that.
    • The Chairman, who had previously been something of a Reasonable Authority Figure and a good counterpart to the Director but with a ruthless streak and hints of some ulterior motive, is officially outed as this at the end of Season 12. As it turns out, he's Control, the one who wants to take over Chorus for its rich supply of lost alien technology, and hired Felix and Locus to manipulate the Civil War of Chorus until everyone is dead, so that he can reap the benefits of the planet once it's clear.
  • This video by DarkMatter2525 seems to take this stance about Yahweh.
  • Tonin: Pai-Meio was just pretending to be good and helpful until Tonin defeated Vilano-san. He reveals his true colors once Vilano-san is seemingly killed and starts taking over the village the defeated villain used to rule.
  • In this GoAnimate video, Caillou befriends a "meme police" officer after being caught using discredited memes by her and they seem ready to set off to find fresher memes when they discover that all of their memes are outdated. Near the end of the video, however, out of nowhere the woman reveals herself to be a spy for Boris and Doris and gets Caillou (and Rosie, who broke her legs with a mallet) grounded.
  • RWBY: The nameless narrator of the first episode seems to be cynical and depressed, with a bitterly pessimistic view of the world's chances against the Creatures of Grimm. Then, in the volume 3 finale she is revealed to be the Big Bad Salem. All her talk about how humanity had no chance was a threat.
    Salem: It's true that a simple spark can ignite hope, breathe fire into the hearts of the weary. The ability to derive strength from hope is undoubtedly mankind's greatest attribute. Which is why I will focus all of my power... to snuff it out.
  • TOME: The Netking named Rubirules seems friendly, (if not slightly egotistical,) but was actually the one leading the hackers, and was generally responsible for the events of the series.

    Web Original 
  • In The Gamer's Alliance, several seemingly heroic characters such as Cain, Desdemona, Mordecai and Vaetris end up having been evil all along during the Godslayer era.
  • In Noob, both the webseries and novel have the Noob guild manage to hire a replacement for Arthéon after he has to start attending Boarding School. Too good to be true for a Ragtag Bunch of Misfits that is dragging around the reputation of being the worst guild in a fictional MMORPG? Yes.
  • In Nan Quest, Henry, one of the first secondary characters that Nan meets and one of her two potential Love Interests, is actually a a vicious, Ax-Crazy killer called "The Pilgrim", who plans on sacrificing Nan in a desperate attempt to escape the hotel.
  • Clawing at Glass introduces the sweet, perky wing-sage Zada as Jondi's aide and a major source of emotional support in his life, constantly encouraging Jondi to cling onto the best parts of himself and even getting him to go on a field operation that ends with almost everyone there slaughtered by monsters. As it turns out, Zada orchestrated that event in league with the Big Bad Duumvirate the whole time, as part of her twisted fascination with the goodness inside Jondi—that she can't and never has been able to feel or understand.
  • In the final chapter of Smirvlak's Stone, not only is it revealed that Nickolas Corveel's protective brother, Gnekvizz, is secretly part of a cult and wants to destroy all life on earth, but he also murdered their parents.
  • The sixth chapter of Help Not Wanted reveals that kind ogre Ogrell Syn'Gorrsh is in fact a cannibalistic Serial Killer who was Obfuscating Stupidity.
  • Howto Hero discusses the possibility that a reformed villain might secretly be this.

    Western Animation 
  • In the Adventure Time episode "The Enchiridion!", Finn saves a group of creatures who are trapped in a pool of lava, not realizing that they're actually Ax-Crazy monsters who love killing old ladies.
  • Alpha Teens on Machines has an interesting example of this trope. In the first season, industrialist Mr. Lee seems to be the team's mentor. In the second season, The Reveal is that he's been a Corrupt Corporate Executive and a Mad Scientist all along. He uses DNA samples from the Alpha Teens to create the Mu-Team, an evil, superpowered group of Psycho Rangers.
  • Many episodes of Archer use this as a last minute reveal. In "Honey Pot," there wasn't even a strategic advantage to the villains pretending to be good guys; they just genuinely liked Woodhouse and wanted to have some fun with him.
    Charles: Oh, we're a hit squad. Forgot to tell you.
  • Buzz Lightyear of Star Command: When Buzz finds out his dead partner Warp Darkmatter working for Emperor Zurg, he goes through just about every sci-fi cliché (Brainwashed and Crazy, Evil Clone, Robot Double, etc.) to justify why his friend is working for the enemy. Warp insists he's been working for Zurg as long as he's known Buzz. By the end of the series, though, Warp seems to be a Friendly Enemy, at one point pretending not to get Zurg's messages and letting Buzz go.
  • In Disenchantment, Bean's Missing Mom Dagmar turns out to not only be alive (kind of), but is apparently working with Cloyd and the Enchantress, and uses her family's trust in her to secure them the victory in the first season finale.
  • Several of the characters encountered by the kids in Dungeons & Dragons turned out to be this, usually because they were Venger in disguise. (The very first episode had him posing as Merlin.)
  • Throughout the duration of Ed, Edd n Eddy, Eddy periodically brings up his unseen older brother, usually building him up to be the coolest, toughest guy in Peach Creek. In Ed, Edd n Eddy's Big Picture Show, we finally get to see him face-to-face... and it turns out that he's a sadistic Big Brother Bully who constantly abused Eddy before he went away.
  • Futurama plays this for laughs with Bender. Particularly in "The Lesser of Two Evils", in which Bender's Evil Twin Flexo has apparently stolen their valuable cargo - but was actually trying to inform them that Bender had stolen it.
  • Green Eggs and Ham: "Evil" may be a stretch, but it turns out that Sam isn't as innocent as he lets on and broke Mr. Jenkins out of the zoo not to return him to his habitat, but to sell him to an evil animal collector.
  • In his first appearance on Kim Possible, Kim doesn't realize that Monkey Fist is a villain.
  • The Legend of Korra: In season two, Varrick's true nature is revealed to be that of a Corrupt Corporate Executive, staging thefts of shipments in order to drive Future Industries into bankruptcy so he can buy a controlling interest and taking advantage of the Water Tribe Civil War to expand his business.
    • It's also later revealed that Korra's uncle was a member of the anti-authoritarian Red Lotus group who wanted to kidnap her as a child to brainwash her into their anarchist ways (kind of odd for a guy went out of his way to frame Korra's father out of his right to rule the Northern Water Tribe), but even they didn't plan on him fusing with the spirit of Chaos.
  • Miraculous Ladybug: "The Collector" reveals first that Gabriel Agreste is, as many fans predicted, actually Hawk Moth, and that his assistant Nathalie is aware of this and is helping him.
  • Cozy Glow in Season 8 of My Little Pony: Friendship Is Magic turns out to be the true Big Bad of the season.
  • Ninjago: the meek and eccentric Dr. Saunders who debuted in the special episode "Day of the Departed" is actually a villain named Krux who is the main antagonist of Season 7 and has been waiting for his brother's return to enact a revenge plan on Ninjago.
    • And then there's Princess Harumi, who at first appeared to be a Love Interest for Lloyd and a major new supporting character. She is, in fact, The Quiet One, and the Big Bad for the season she appears in (as well as a Manipulative Bitch).
  • Over the Garden Wall: Beatrice spends about half of the miniseries leading Wirt and Greg to "Adelaide of the Pasture, Good Woman of the Woods", implied to be a sort of Fairy Godmother who can send them home. The twist is that Adelaide is a Wicked Witch in service of the Beast, with Beatrice (who, to be fair, wasn't fully aware of Adelaide's true nature) working for her to break the curse on her family.
  • In the second season finale of Rapunzel's Tangled Adventure, Cassandra steals the Moonstone for herself and undergoes a transformation.
  • Samurai Jack has this pulled with a mysterious female swordsman who teams up with Jack in an early episode. Turns out she's Aku in disguise the whole time. The twist actually marks a rare The Bad Guy Wins ending for the episode.
  • It's a common practice for just about every Scooby-Doo show to have at least one episode where the costumed crook's true identity was a person who had earlier pretended to be an ally toward the Mystery, Inc. gang.
  • Sheep in the Big City spoofed this in the season one finale "To Sheep, Perchance to Dream", where the episode's twist ending reveals that Sheep was the real villain all along and that he intended to use the show's narrator Ben Plotz in a narrator-powered ray gun. This is completely disregarded in the second season.
  • The Simpsons:
    • In "Brick Like Me", Homer retreats into a Lego-themed Happy Place to escape his fear of Lisa leaving him behind. The Lego! Comic Book Guy seems like a Helpful Hallucination... until Homer decides it's time to face reality.
    CBG: All you need to do is open the box back to your so-called reality. But I. Can't. Let. That. Happen. (rotates his Lego head to a menacing expression)
    Homer: Huh? You're the bad guy? I thought you were the rule-explainer-guy!
    • In the much earlier episode "Krusty Gets Busted", Sideshow Bob is a straight example of this trope when it turns out that he framed Krusty out of a malicious attempt at getting back at him for the times he mistreated him.
    • In "The Boys of Bummer", Bart meets up with retired baseball player Joe LaBoot, who appears to be sympathetic towards Bart's problem. Upon learning who he is, however, he shows his true colors when he maliciously chastises him into tears.
    LaBoot: Bart? Are you Bart Simpson? The kid who dropped that easy fly ball? You stink like a Dutchman's throw-up! Talking to you is the biggest error of my life!
    (Crowd boos at Bart)
  • SpongeBob SquarePants: In New Leaf, it appeared that Mr. Krabs and Plankton had finally reconciled and were friends again. Krabs trusts him so much now that he gives him the Krabby Patty formula... but then it turns out that Plankton was faking it all along, saying that he finally won. Yet Krabs revealed that he had outfoxed him first.
  • The Magic High Commission from Star vs. the Forces of Evil initially seem to be the flawed but heroic Big Goods... until it’s slowly revealed that they’re actually selfish, controlling, and short-sighted bigots who are responsible for (or exacerbated) many of the terrible things that happen over the course of the series, including Meteora’s descent into villainy and the Mewman kingdom’s discrimination against monsters. By the final season, they gleefully support the Big Bad in a coup against Eclipsa and even create new Solarian Warriors for her, not realizing that she’s not going to stop at just overthrowing Eclipsa and could potentially destroy the world.
  • Star Wars: The Clone Wars: In the Umbara arc, General Pong Krell seems to be a heroic, if jerkish Jedi at first. It turns out that he is secretly planning on becoming Dooku's new apprentice and is willing to sacrifice clones to sabotage the Republic war effort.
  • Steven Universe: In "Room for Ruby", Navy, the Ruby Squad member that seemed the nicest and least malicious of the five, turns out to be a lying, manipulative sadist with a sugary personality. She fakes defecting to Earth and gets in the good graces with Steven and Peridot (while Lapis remains suspicious), all so she can steal back her ship and rub it in Steven's face. Steven did lie to her, trick her and space her, but while Steven did it out of necessity, Navy took a perverse pleasure in her actions.
  • In Stretch Armstrong and the Flex Fighters: Powerful businessman and the Flex Fighters' mentor and benefactor, Jonathan Rook, turns out to be the villainous Stretch Monster, and has been manipulating them and some of the show's other villains for his own ends. Near the end of season two, Malcolm Kane, Rook's seemingly unwitting right-hand man, is revealed to be Number One, the leader of the Tech Men, who has been undermining Rook by pretending to be loyal to him, all while hatching his own evil plan.
  • Pumyra in ThunderCats (2011) was revealed to be The Mole who was working for Mumm-Ra the whole time. Unfortunately, the episode in which this revelation occurred was the last one produced.
  • In Totally Spies!, Terrance and Dean first seem like Dean was evil all along. Then Dean turned out to be good all along. The same goes for the episode in which Tim Scam was introduced. It also applies for a lot of "villains of the day".
  • In Ultimate Spider-Man, Deadpool turns out to be this. (Or very least, Amoral All Along.) First introduced as a freelance hero who used to work for S.H.I.E.L.D.; he's later revealed to be a amoral mercenary who will work for the highest bidder.
  • Throughout The Venture Bros. Dr. Jonas Venture Sr. was slowly revealed to be an Abusive Dad and habitual womanizer whose negligence and lack of morality led to things like a group of orphans being trapped under his compound for 30 years, but Season 7's "Morphic Trilogy" cemented his status as a villain when it was revealed that he blackmailed his friend the Blue Morpho into doing his dirty work (after possibly sleeping with his wife) and rebuilt him as a cyborg after his death, only to try to betray him again and steal his body after Jonas became a Brain in a Jar.
  • In season 2 of Wakfu, Qilby appears to be a friendly mentor to Yugo. He's actually an insane Omnicidal Maniac scheming to claim the Eliacube so he can go back to draining entire worlds of their wakfu.
  • In season 2 of Winx Club, the new teacher Avalon appears to be an evil impostor in the end.
  • Young Justice opened its revival with a version of Batman and the Outsiders character Helga Jace seeming to be the Token Good Teammate of Baron Bedlam's operations and a Reluctant Mad Scientist, then willing to help the heroes to atone for her role in things. Come "Antisocial Pathologies", and it turns out that much like her comics and Black Lightning counterparts, she's insane, evil, and very much a willing Mad Scientist.


Video Example(s):

Alternative Title(s): The Bad Guy All Along



It turns out that supposed New Repulic ally & Jerk with A Heart of Gold Felix, was actually working with Locus all along, helping to manipulate the war of Chorus.

How well does it match the trope?
