* When Mike and Sully first uncover Randall's plan in ''WesternAnimation/MonstersInc'', Sulley goes to Mr. Waternoose for help. Five minutes later, he has asked them [[HaveYouToldAnyoneElse if anyone else knows about it]] and has banished them to the human world.

'''WARNING: Examples can be major spoilers for a climactic [[TheReveal reveal]]. Read ahead at your own risk.'''

* In ''VideoGame/{{BioShock|1}}'', [[spoiler: your guide throughout most of the game, former revolutionary figurehead Atlas, turns out to be mobster Frank Fontaine, who was thought dead according to the back story. You're [[TomatoInTheMirror a genetically-altered and hypnotically-conditioned assassin]] created by Fontaine as part of his scheme to seize control of Rapture from Andrew Ryan, and Atlas's CatchPhrase "Would you kindly..." was actually [[TriggerPhrase the command phrase to make you obey his orders.]]]]

* In both ''VideoGame/MetalGear'' and ''VideoGame/MetalGearSolid'':
** The player-hero receives advice via radio [[spoiler: much of which is revealed to come from each respective game's BigBad.]]

** ''Subverted'' in ''VideoGame/MetalGearSolid4''. Drebin [[spoiler:was put in place by the AncientConspiracy...in order to help Snake defeat the BigBad]]. He also makes it clear from the beginning that he [[WildCard works for everyone who can pay him]], and is telling the truth when he says he won't betray his customers, Snake included. He even saves the man's life on occasion.

* In ''VideoGame/ModernWarfare 2'', [[spoiler:General Shepherd, the main US Army commander, is TheChessmaster and ultimate BigBad, having manipulated the massive invasion of Washington DC and the war between the US and Russia to demonstrate the US's military might as revenge for having 30,000 of his troops nuked in the first ''Modern Warfare'']].

** ''VideoGame/{{Persona 2}}'' features a variation; in both games, the Time Count provides useful services -- ones that can't be gotten anywhere else in Eternal Punishment. He turns out to actually be an avatar of Nyarlathotep, the BigBad. Unlike most examples, it's not part of some overarching scheme -- being a trickster and manipulator, he decided it'd be more fun this way, and arrogantly believed that even if he helped them, the heroes couldn't possibly defeat him.
** In ''VideoGame/{{Persona 3}}'', [[spoiler: it turns out that Shuji Ikutsuki was actually trying to summon Nyx and end the world since long before the game even began, and that serving as the mentor for SEES was his way of using them as a weapon to accomplish this task. Without his own Persona, he had no way of defeating the Full Moon Shadows who needed to die in order to free Nyx, so he found some people who could get the job done, and...]]

* In the ''WesternAnimation/MenInBlack'' AnimatedAdaptation, Kay's first partner and mentor Alpha turned out to be a scheming bastard. When Kay refused to join him, Alpha shot him and left him for dead. It's no wonder Kay became an emotionless robot after that.

* In the ''Franchise/PuellaMagiMadokaMagica'' series, MentorMascot Kyubey is revealed in the original anime and manga as the true BigBad and a HiveMind species who set up the Puella Magi system so contracted magical girls will inevitably [[AndThenJohnWasAZombie become witches]], and intends the [[KillAllHumans destruction of humanity]] to use their energy to power the universe. In almost all installments, they deceive the girls into contracting and get them to make a wish that will [[JackassGenie almost inevitably backfire]], leaving out critical information about being a magical girl and justifying it by saying YouDidntAsk, to intentionally drive the girls to despair, which will turn them into witches. The only exception is ''Manga/PuellaMagiTartMagica'', where Cube, the Incubator unit, is completely honest to Jeanne and actually grows to care about her to some extent.

---> [[spoiler:Barlowe: How dare you... even forget... who raised you... you... STUPID DISCIPLE!]]

* In ''VideoGame/WarioLand 3'', Wario gets advice from a sealed away mysterious figure who will apparently give him riches and power if released. But sadly for him, it turns out this figure is actually Rudy the Clown, a MonsterClown who conquered said pocket universe the game is set in and transformed all the people into monsters.

--> [[spoiler:Barlowe: How dare you... even forget... who raised you... you... STUPID DISCIPLE!]]

%% * From ''VideoGame/AssassinsCreedI'' [[spoiler: Al-Mualim is not only a Templar himself, but the BigBad.]]

* In ''VideoGame/AsurasWrath'', [[spoiler:the Golden Spider]] offers Asura cryptic advice several times in the game [[spoiler:while he is in Naraku]] to aid him in his battle against the Deities. [[spoiler:The Spider is actually behind the rise of the Gohma (and consequently the Deities' villainy as well) which was apparently a test of the Deities' worthiness to wield Mantra, and he's only aiding Asura because he wants to claim Mithra as his vessel and is grooming him to be his heir.]]

So the {{heroes}} consult a {{mentor|archetype}} when they're battling TheEmpire, digging up an AncientConspiracy, slaying demons, or something of the sort, and have hit a dead end. Surely they’re in a position to be helpful? After all, they’re the scholar/politician/military person/whatever, and just likely to have the information they need. Not to mention they can keep a secret.

** Subverted with Daitokouji-sensei, Judai's teacher and ally, who was revealed to be TheMole, and then later TheMole for the good guys.

* In the first ''VideoGame/BookwormAdventures'' game, [[spoiler:Professor Codex appears to be happy to help Lex the bookworm rescue [[DistressedDamsel Cassandra the oracle]]. However, Lex learns that the BigBad who kidnapped Cassandra wasn't {{Dracula}}, as Codex told him, but Professor Codex himself, who used his imprisonment of Cassandra (and Dracula's apparent kidnapping of him) to maneuver Lex into fighting the books' monsters and unknowingly breaking the chains of fiction that kept them in the books. Thanks to Lex [[NiceJobBreakingItHero doing such a great job]] with these monsters, Codex can now control them as his minions.]] Fortunately, he gets a final boss battle to set things right.

* In ''Film/TheWitchfiles'', Jules is the [[GothGirlsKnowMagic goth girl]] who introduces the other girls to magic and gets them to form a coven. She is also a [[Really700YearsOld 300 year old]] witch who returns to Brunswick every 17 years, forms a coven, and then drains the life force from the other members to maintain her youth and vitality for another 17 years.

* In ''Comicbook/{{Bookhunter}}'', after the Library Police finally retrieve the stolen book, Agent Bay realizes that the stolen copy was actually another forgery--because the original book had already been stolen by the Chief of Library Security.

* The French series ''ComicBook/LaQueteDeLOiseauDuTemps'': [[spoiler:Mara, the old witch-princess who sends the heroes on the quest in the first place]], secretly wishes to steal the powers of the GodOfEvil as opposed to [[SealedEvilInACan sealing him]].

* ''Comicbook/SpiderMan'':

%% * ''[[Literature/DeltoraQuest Deltora Quest]]'' has a textbook example with [[spoiler:Mother Brightly]] in its TournamentArc, the Rithmere Games.

* Literature/RomanceOfTheThreeKingdoms has several, including one who served Liu Bei but was tricked into serving Cao Cao; he refused to give meaningful advice from then on and kept his mouth shut when he saw through the ruse at Chi Bi. More importantly, [[spoiler: it's the descendants of Sima Yi, Cao Cao's strategist, who ends up unifying the three kingdoms; one Cao son even gets ''murdered in broad daylight'' by the Sima clan]].

%% * [[spoiler: The Elder]] in Terranigma. Also, [[spoiler: Yomi or dark side Yomi.]]

* In Webcomic/{{Pibgorn}}, [[http://www.gocomics.com/pibgorn/2005/01/22/ a succubus can see that our heroes still find him useful]].

* ''ComicBook/RobinSeries'': Ali Ben Khadir, the young leader of Dhabar, meets Ulysses Armstrong, otherwise known as "The General", and is impressed by someone near his own age with so much military knowledge. The two become friends while talking strategy and military history and Ali invites Ulysses to come back home with him as a military advisor. After arriving in Dhabar Ulysses gleefully uses his new position to try and start a war even though Ali wants peace.

* ''FanFic/MegaManDefenderOfTheHumanRace'' has Governor Deacon's adviser, Newkirk, who didn't have well-laid plans. While not outright treacherous, he showed little to no concern for public safety. This got Newkirk fired.

The dead giveaway for this character type is accepting the heroes' theories with a complete lack of skepticism. If it were anyone else, the first thing out of their mouth would be, "Why should I believe you?" If the character says "[[HaveYouToldAnyoneElse Have you told anyone else]]?" or "It's a good thing you came to me." be warned: they're either about to give TheReveal or planning on making some calls and starting a massive cover-up as soon as the hero leaves the room.

%% * ''[[Series/TheFlash2014 The Flash]]'': [[spoiler:Dr. Wells turns out to be the Reverse Flash AKA the Man in Yellow. He is later revealed to be Eobard Thawne, who used a device to kill the real Dr. Wells and [[FaceStealer steal his identity]]]].

* From ''Series/{{Heroes}}'':
** Claire has been hiding from her father the fact that she heals incredibly fast. She finally can't take the pressure anymore and decides to tell him... and he tells her he already knows and asks her whom else she's told. Subsequently, every person she mentions has their memories of it wiped, and Claire herself is targeted for a wipe.
** In an ironic twist, though, HRG was trying to ''protect'' Claire (and the others) by doing this.

* ''VideoGame/KirbysReturnToDreamLand'' has [[spoiler: [[BitchInSheepsClothing Magolor]]. The reason why he tasked Kirby and friends to repair his spaceship and defeat [[OurDragonsAreDifferent Landia]] is because the dragon is guarding [[CrownOfPower the Master Crown]] to keep it out of evil hands. Magolor's first attempt to beat Landia resulted in the Lor Starcutter being shot down, thus kicking off the plot, and he reveals his true nature to Kirby after finally claiming the Crown for himself.]]

* ''VideoGame/KirbysReturnToDreamLand'' has [[spoiler: [[BitchInSheepsClothing Magolor]]. The reason why he tasked Kirby and friends to repair his spaceship and defeat [[OurDragonsAreDifferent Landia]] is because the dragon is guarding [[CrownOfPower the Master Crown]] to keep it out of evil hands. Magolor's first attempt to beat Landia resulted in the Lor Starcutter being shot down, thus kicking off the plot, and he reveals his true nature to Kirby after finally claiming the Crown for himself.]]

* In the SNES ''Film/JurassicPark'' game, Dennis Nedry will occasionally call the player and give false information such as spitters giving you more life, raptors only attacking you if you move, approaching a T-Rex will give you a OneUp, or it's okay for you to touch the electric fence. He'll even sometimes say "SUCKER!" when calling you at times.
