There are people who we idolize, and who change us forever. These mentors and idols teach us to use our full potential and do great things, and we love them for this. We will be forever loving of them; without them, we would be nothing.
And if you're a TV character, chances are high that they are the scum of the earth, or at least have come to be by the time you meet them again—especially if the audience has just heard about them for the first time. If you're in law enforcement, you can count not only on being forced to learn of their darkest secrets, but also on being the one who has to arrest them. Expect them to have abandoned their ideals, switched sides, or been Evil All Along.
The hero is likely to recite one of the mentor's or idol's old quotes to show how far they have fallen or highlight their hypocrisy.
Most of the time, this disillusionment is the result of the idols taking great pains to hide their dark secrets, but sometimes, those who worship them also had an overly idealized image of them.
When the mentor or idol is actually worthy of the admiration, but is flawed enough to make them unlikeable, that's Warts and All.
Related to Beleaguered Childhood Friend and Big Bad Friend. Compare Fallen Hero and Historical Hero Upgrade. Contrast with Evil Mentor, who was Obviously Evil from the beginning. Not to be confused with Broken Base. Also contrast Rebuilt Pedestal, when a formerly Broken Pedestal is forgiven or exonerated. Contrast with Blind Obedience, where this usually isn't the case.

Anime & Manga
Zaied from Full Metal Panic! is a mild version of this. Not that Sousuke really worshipped him or felt so eternally grateful to him...but Zaied was a respected memory to Sousuke of an honorable, dead comrade of the past. Needless to say, any feeling of goodwill on Sousuke's part completely vanishes when he realizes that Zaied decided to team up with Gauron and kill a bunch of his current comrades. Let's face it - Zaied's alliance with Gauron was enough to piss Sousuke off to the point where he thinks absolutely nothing of killing Zaied, and is afterwards never shown to ever think about the guy again.
An indirect example: In the Sakura Taisen TV series, Kohran idolizes the inventor of the kohbu armor, whom she knows only by reputation and from the notes and plans he left behind. When she discovers that he switched sides long ago and now leads the demonic forces against which she and the other Hanagumi fight, she undergoes a crisis of faith.
Sara Werec of Soukou No Strain learns that her beloved brother has gone insane, defected and killed her friends. (Pithy statement: "Only you can do what you've decided to do. If you feel that way, there's nothing you can't do.")
Zelgadis from Slayers looked up to his guardian and great-grandfather Rezo, a powerful spellcaster, as the epitome of good, nobility and selflessness. He even allows himself to be turned into a monstrous chimera (part human, part golem, part demon) in order to be stronger and more able to further Rezo's cause. Understandably, Zel is quite bitter when he finds out that everything Rezo was doing, up to and including his experiment on Zelgadis, was intended only to find a cure for his blindness. What Rezo failed to realize is that his blindness is a seal. By opening his eyes a fragment of Ruby-Eyed Shabranigdo awoke, destroyed his body, and nearly destroyed the world.
Naruto revealed that Itachi's massacre of the Uchiha clan happened with the approval of Konoha's elders, the end result of the village's fear and suspicion of the Uchiha clan ever since Madara's one-man rebellion when he was denied the position of 1st Hokage. However, this is somewhat mitigated by the fact that the Uchihas really were planning a coup. It's also worth noting that while the Third Hokage knew the truth behind the massacre, he did try to prevent it from happening.
An interesting example is Naruto toward the Fourth Hokage. In the first chapter Naruto admits to having a deep respect for the Fourth due to his actions and abilities. He never shows any change in attitude towards the man until actually meeting him, at which point Naruto promptly punches him while yelling about how tough his life was thanks to the sealing.
In the second Shippuden movie Shinnou turns out to be one for Amaru. Amaru is quite shocked, but separates the person who taught her medicine and served as an inspiration to save lives and the person who is the Big Bad.
In the Six-Tails arc, Utakata has one in his master, whom he killed as he tried to extract the Six-Tailed Beast. It's played with as Utakata hears that his master did it for his own good, but Utakata refuses to believe it until it's finally subverted when Utakata realizes, with Naruto's help, that his master wanted to help him. In the same arc, there's also Shiranami for Hotaru.
Chapter 599. The look on Kakashi's face once he realizes just who Tobi is is heart wrenching, especially considering that Obito was remembered as a hero of Konoha and was the one who inspired Kakashi to consider bonds with comrades most important. The fact that Kakashi spent years trying to live up to Obito's loyalty and kindhearted nature, to the point of emulating his personality and mannerisms as a memorial to him, just makes it worse and drives the knife in even deeper than it already was.
At the start of Monster, Tenma greatly looks up to his boss and seems to view him as a father figure. Said boss exploits his surgical skills for media publicity, plays political games that get one of Tenma's patients killed, and screws Tenma's career over for daring to defy him.
Nine years later, Tenma still tells his patients about that young boy he's so proud to have saved. Yeah...
Its implied in episode 20 of Code Geass R2, and confirmed in the subsequent episode, that Empress Marianne is Lelouch's broken pedestal, by virtue of being complicit in her husband's Assimilation Plot and abandoning Lelouch and Nunnally for years, among other things. She's certainly quite the Magnificent Bitch and Lady Macbeth, instead of the borderline Purity Sue that Lulu thought she was.
In Genesis Climber MOSPEADA (a.k.a. Robotech's Invid Invasion saga), Stig ("Scott") Bernard's mentor and hero, Major Johnathan ("Colonel Johnathan Wolff") has sold out to the Inbit, running a free town of would-be rebels while leading the most serious ones into certain death. He does experience Redemption Through Death by the end of the episode.
The Robotech example gets subverted in Robotech: The Shadow Chronicles. There we see Marcus Rush, Marlene's little brother who wants to avenge their (presumed for Scott) deaths. When he meets Scott, he is overjoyed and regards him with high respect...until he finds out about Ariel, at which point he goes berserk. The subversion is that Ariel IS a friend, even if she is Invid.
Subverted in Hamtaro. Laura finds out that her favorite pop singer, Glitter, is a sharp-tongued Yandere who tried to steal her crush Travis, but at the end of the episode, she writes in her diary saying that she feels sorry for her.
Azusa to Yui in K-On! is a mild example because her worship doesn't turn to hate like every other case here, but it still fits: she's inspired to join the Light Music Club after their performance in the high school entrance ceremony, admiring especially the frontwoman (whose little sister is a friend of hers). As it turns out, she knows more about musical theory than Yui (who really doesn't know one iota of it) and is absolutely appalled to see that she spends 90% of her time in the club slacking off rather than actually, you know, rehearsing or training. In the end, it's Azu-nyan who snaps at Yui when she screws up horribly at their school festival performance. And all of this in one manga volume.
In Zatch Bell!, when under Zofis's control, it seems like Koko is this for Sherry.
One Piece - Dr. Hogback for Tony Tony Chopper, as Chopper realizes that he was doing research on zombies, and enabling Moria to create an army of beings that should not naturally be alive. Hogback also admits that he was in medicine for the money and he doesn't particularly care what Chopper thinks of him (although he does point out that he plans to kill Chopper and reanimate his corpse with a shadow so that he can serve the doctor he admired).
Vice Admiral Vergo for the marines of G-5, who admired him for taking command of marines who couldn't fit in anywhere else, until it turned out that he was working as The Mole for Donquixote Doflamingo and was responsible for the children being kidnapped.
Caesar Clown for Brownbeard, who pretty much worships the ground he walks on after he saved him and his crew, only to find out that he doesn't return the respect in the slightest and only treats them as expendable forces.
Kyoshiro to Towa no Sora has Ayanokouji Kazuya, the presumed deceased older brother of the main lead, Ayanokouji Kyoushirou. Kazuya was originally portrayed as Kyoushirou's, unsurpassable better: the handsome, intelligent, diligent scientist who sacrificed himself in an attempt to prevent a lab accident involving the release of the Absolute Angels from destroying the world. Toward the end of the series, Kyoshiro and Kuu find out that Kazuya engineered the accident with the intent on wiping out all life on the planet so that he could be alone in his utopia with his beloved, the most powerful of the Absolute Angels. Also, he survived the first explosion and is more than willing to try it again.
Graham could very well be one for Hayate, too, but we don't know if she knows the truth about him. Granted too, he still did a lot that was respectable, accepted he was in error and got off with just resigning his TSAB post.
After being rescued, by the titular character in the first episode of Magical Girl Lyrical Nanoha StrikerS, Subaru had admired Nanoha almost to the point of worship and was genuinely happy that she has been given the opportunity to work with her idol. When Nanoha shot down her partner and friend mercilessly during training as punishment for insubordination and afterwards removed said partner from combat readiness during an operation she was visibly upset. The trope gets subverted after she learns why Nanoha acted the way she did: she was looking out for her trainees' well being by planning their training regimens step by step to avoid the necessity of Training from Hell, something that Subaru's partner constantly subjects herself into as Nanoha herself suffered almost career ending injuries when she was younger because of overtraining. After this, Subaru's admiration for Nanoha returned and possibly intensified even more.
Detective Conan loves to apply this trope to murderers and victims. The best example comes when Conan Edogawa, during the "3K's of Osaka" storyline, realizes that his idol, the famous European soccer player Ray Curtis, is the murderer of the week. Not only that, but the rumors about his heroin addiction were, in fact, true.
Ran goes through this twice. First, the karate champion she idolizes is Taking the Heat for his girlfriend, the true murderer. Later, she not only finds out that her favorite school teacher also was the killer of the week, but has to actually reveal the truth, making said episode a massiveTear Jerker.
Another instance involves a woman who worked at a pastry shop and was kind to Ayumi...who had lured her downstairs neighbor under her window and dropped a flower pot on her head. Ayumi didn't want to believe she could have done it, and was broken-hearted when it turned out she did.
It happened again when the Detective Boys investigated a case of "self-defense" by a man Mitsuhiko idolized and discovered it was actually premeditated murder.

Rio Kurotori for Biko, and to a lesser degree, Muhyo and Yoichi in Muhyo And Roji, although Biko seems to forgive her after she defects from Ark.
Gilbert Durandal in Mobile Suit Gundam SEED Destiny. Just...everything about him qualifies. As ZAFT's Glorious Leader and an apparent moderate he was idolised by his own followers and much of the world. And then we find out that he's a Well-Intentioned Extremist who aims to make the world a better place by imposing a genetic determinist utopia. In the end, much of his fleet switches sides after this gets outed. His last real follower, Rey Za Burrel, is the one who does him in after Kira gives him a Breaking Speech.
Earlier, in Mobile Suit Gundam SEED Astray, Kisato Yamabuki is shown to be a major fan of George Glenn, the first Coordinator. When the GG Unit, a device containing the algorithms of the man's brain, is hooked up to a hologram on the ReH.O.M.E., Kisato's shocked to find out that the man is laid-back and scatterbrained and not the pioneer that she invisioned him to be. On the other hand, Glenn admits he didn't become a Coordinator for any particular purpose and later tells Lowe Guele that a true Coordinator is just one who betters himself at life.
Charmander. Completely oblivious to the fact that his Jerkass of a trainer abandoned him because he was weak, waited for the day for that trainer to return, even through a fierce storm (which would be fatal to Charmander, had it not been for Ash and friends).
Similarly, Shamus for Tepig. After the pedestal is crushed and he suffers a brief Heroic BSOD, Tepig evolves into Pignite in a Heroic Resolve.
A major plot point in Pokémon: Lucario and the Mystery of Mew is that Lucario believed that the Knight of Aura that he looked up to, Sir Aaron, abandoned Cameron Palace in its time of need. It was not helped by the fact that, the last time Lucario saw him, Sir Aaron sealed Lucario inside of a staff seemingly for no reason at all. However, Lucario would later learn that Sir Aaron in fact did save the kingdom by sacrificing himself, and he sealed Lucario because he didn't want the Pokémon to follow him and do the same thing.
Captain Sosuke Aizen to everyone in Bleach, especially to his lieutenant, Momo Hinamori.
With Tousen with both his long-time friend Komamura and his vice captain Hisagi.

In the anime-only Zanpakuto Unknown Tales arc, Koga for Muramasa, who betrays him after being freed from his seal.
Soifon regarded Yoruichi this way after her defection though, truthfully, it had more to do with abandoning her than breaking the law. What's worse, Yoruichi never offers her an explanation for it.

According the Official Bootleg, they've since reconciled their differences and their bond is as strong as ever.

Another pedestal is smashed in its gaiden series Saki Achiga-hen. Arata really idolized Akado Harue and was greatly disappointed when the latter stopped playing mahjong after a crushing defeat in a very important match (cross-checking with Saki reveals that she lost to Sukoya).

Guts has the misfortune of having gone through two of these in Berserk, both of whom betrayed him in unforgivable fashion. The first was his adoptive father Gambino, who first taught him how to fight as a wee little boy, but who had him raped by one of his men and eventually got drunk and tried to murder him, both acts of which were done out of hatred for him born from blaming him for the death of his lover Sys, itself born from the superstitious belief that a child taken from a corpse is bad luck. The other was Griffith, who refined Guts' fighting skills and made him an able battle commander, but who was also a Manipulative Bastard who became obsessed with him over time, which would lead to him falling apart when Guts left the Hawks, growing to hate him during his year of torture, and finally hitting his Despair Event Horizon upon learning Guts was in a relationship with Casca, his Number Two, and were discussing the possibility of leaving him behind, which would set off the events of the Eclipse in which Griffith betrayed and sacrificed everyone he'd led to the Godhand to become their fifth member, Femto — and then went on to personally betray Guts further with what he did to Cascaright in front of him.

After Miho summons the nerve to ask her mother whether this was necessary, her sister goes up to her, apologizes for her aloof behavior and tells Miho to find her own way of tankery; the last scene of the chapter also indicates that Maho is trying as hard as she is to be a good Nishizumi heiress so that Miho can live the way she wishes.

Hivefled; Gamzee is at first overjoyed to discover his own ancestor, the Grand Highblood, is taking him as a personal apprentice. Thatdoesn'tlastlong.
In Story Of The Century, the pedestal Light has been on becomes broken when it's found out that he really is Kira and had been all along. It's also implied that the task force loses a lot of trust and respect for L too, given everything he did throughout the investigation. L ends up Dying Alone by the end, mostly by choice.
Erin: Forget trust and respect, I don't even know how they stand you after what you've done to them.
In the sequel, this is what triggers Mello's Face-Heel Turn. It can be inferred that Near has undergone a similar reaction since he found out about L's death around the same time, but he takes on his title anyway and so far hasn't shown signs of being explicitly evil. Dickish and creepy, though? Definitely.
In Diaries of a Madman, Celestia and particularly Luna's reputations take a severe hit over the course of the story, as various events and scandals catch up with them. It is suggested that Luna is trying to drag her sister down with her as well.
In The Masks We Wear, Prince Zuko learns that General Iroh and the Order of the White Lotus want him to 'redeem' the Fire Nation by helping the Avatar overthrow his father and become a puppet Fire Lord in all but name. It does not end well.
System Restore: Hinata struggles with this after it comes out that Komaeda, whom he considered an easygoing and helpful friend, was secretly planning to murder somebody at Togami's party. This is made worse by how he isn't able to get any closure, due to how Komaeda ended up being the first victim, meaning he never got a chance to explain himself.
The second chapter has a double-whammy of this. Togami's hit hard when he realizes that Pekoyama, whom he saw as one of his most dependable allies, let Kuzuryuu play Twilight Syndrome and set into motion the second murder, and Koizumi is also upset to hear that Pekoyama, whom she regarded as a friend, tried to convince Kuzuryuu to kill her. Before Togami can properly recover from that, everyone gets blindsided by the second murderer's identity, especially Souda and Tanaka, who had feelings for her.
Mito is this for Tsunade in Eroninja. Tsunade always imagined her grandmother to be a Proper Lady, but when she's resurrected Tsunade learns that Mito only acted as this after her husband died to keep the nobles and council happy. In reality she's a Hard-Drinking Party Girl. Thankfully they later reconcile.
Later this also happens between Kushina and Minato. After she and Naruto are accidentally sent to the past, Kushina admitted to herself that she could accept Minato's refusal to attempt to Set Right What Once Went Wrong after realizing Naruto was right and they couldn't predict what, if any, affect it'd have on the future. What she couldn't forgive though, was that Minato erased his own knowledge that eventually his wife would die and he'd make their son into a jinchuuriki. In her mind, it showed Minato was willing to make horrible sacrifices but but did so in a way he wouldn't have to live with himself for making them.
In Perfection Is Overrated, Ishigami becomes one to his student, Akira when she learns about his plan to manipulate Yukariko into helping him gain control of the Hime Star, which would likely involve defeating her and killing Takumi in the process. Her reaction is understated, but it's implied that she's more upset about it than she lets on.
In the Saki fanfic, Yumi, Maiko Miura Yumi's senpai and old girlfriend turned out to be this, after moving on to university and dumping Yumi for someone else without even telling her.
Rosario Vampire: Brightest Darkness: Dark always lived his life in honor of Arial, who granted him his freedom before she died, while Mizore often gave thanks to Arial at night as well. Come Act VI, when Arial comes Back from the Dead, they discover that she had become infatuated with Dark, nearly killing Mizore in a jealous rage. Dark himself suffers a major Heroic BSOD which, several chapters later, results in a massive Freak Out, believing that everything he had fought for in Arial's name was meaningless. Mizore sums it up quite nicely in Act VI chapter 17:
Mizore: Damn it, I've had enough of this girl. She's not the angel my Dark spoke of. She's not the angel I gave my thanks to at night. She's a fucking nightmare!!
Come Act VI chapter 27, however, Arial realizes and accepts that she is Dark's guardian angel/mother figure and nothing more, and they reconcile. In the case of herself and Mizore, however, things are still quite frosty, no pun intended.

In Treasure Planet, Jim's trust in Silver is broken when he finds out that he is a pirate and the mastermind behind the ship's mutiny. Silver makes up for it in the end, though.
Mr. Incredible, Bob Parr, is this for Syndrome in The Incredibles. As a child, Buddy Pine starts out as Mr. Incredible's self-proclaimed biggest fan, and spends the entire opening sequence of the film trying to persuade the superhero into letting him become his sidekick, "IncrediBoy". However, he repeatedly gets on Bob's nerves until he coldly tells him, "I Work Alone." Soon after, Buddy's attempts to prove himself cost Bob his chance of apprehending one of his archenemies, and he turns the boy over to the police to bring him home. This act disillusions Buddy from not just Bob, but all superheroes in general, leading him to take his frustrations out on all supers as the villainous Syndrome.
In Up, on arriving in Venezuela, Carl Frederickson meets his childhood hero, the explorer Charles Muntz, who has spent his life trying to capture a rare bird that lives on the plateau near Paradise Falls...and has become dangerously obsessed with his quest, to the point of killing people he even thinks are trying to get the bird back to civilization before him, and threatening Carl and Russell.

As everyone knows, in Star Wars Luke Skywalker grows up wondering what happened to his father Anakin, but his foster parents only tell him vaguely that he had been a pilot of a civilian ship and died during the Clone Wars. Obi-Wan Kenobi meets Luke and tells him that Anakin was once his apprentice and one of the most noble and powerful Jedi he had ever known and that he was also skilled as a fighter pilot. Anakin was a war hero who was the very best at what he did, he could fight on sea, air, or land, even in space, and was known as the hero with no fear-his father was someone to be admired. Luke wonders aloud how such a great hero could have died and Obi-Wan tells him that his father was betrayed and killed by the Empire's dark enforcer Darth Vader during the Clone Wars and this causes Luke to hate Vader, even moreso when Vader eventually kills Obi-Wan too. However, Vader eventually reveals the truth to Luke-he is Luke's father, once named Anakin Skywalker, and the Empire's ruthless enforcer of terror and fear Galaxy-wide. Needless to say, he doesn't take this very well.
In Star Trek, Zefram Cochrane is revered as a visionary, the man who invented warp drive and ushered humanity into the stars. In person, he's an alcoholic and depressed man whose only motivation is his own self-benefit. As he puts it: "You wanna know what my vision is? Dollar signs. Money. I didn't build this ship to usher in a new era for humanity. You think I wanna go to the stars? I don't even like to fly! I take trains!" Unlike most examples of this trope, the crew doesn't actually seem that disappointed, or at the very least they hide it well. Ultimately, first contact turns Cochrane into the man that the crew remembers.
The idea behind their lack of disappointment is probably that by the 24th Century, humanity is a much more enlightened race than now, and thus are more capable of accepting the idea that their heroes and idols aren't what they expected them to be. Riker puts it well when he quotes Cochrane from a future speech where he says "Don't try to be a great man, just be a man, and let history make its own judgments."
Nicholas Angel relates such a story about his uncle in Hot Fuzz.
Nicholas Angel: I don't remember a time when I didn't want to be a police officer...apart from the summer of 1979 when I wanted to be Kermit the Frog. It all started with my Uncle Derek. He was a Sergeant in the Met. He bought me a police pedal car when I was five. I rode around in it every second I was awake - arresting kids twice my size for littering and spitting. I got beaten up a lot when I was young, but it didn't stop me. I wanted to be like Uncle Derek.
Danny Butterman: He sounds like a good bloke.
Nicholas Angel: Actually, he was arrested for selling drugs to students.
Danny Butterman: What a cunt...
Nicholas Angel: Probably bought the pedal car with the proceeds. Needless to say, I never went near it again. I just let it rust. But I never lost the profound sense of right and wrong I felt at the wheel of that pedal car. I had to prove to myself that the law could be proper and righteous and for the good of humankind. It was from that moment that I was destined to be a police officer.
If you look carefully when Nicholas is packing up for Sandford, you can even see him taking a picture of a child in a pedal car off his noticeboard.
Gordon Gekko from Wall Street to Bud Fox. Thankfully, Bud gets even.
Baines (who is a composite of several historical characters, but none actually ended up the way he gets portrayed) in Malcolm X helps Malcolm to turn his life around, but is later shown to have motives much less pure than Malcolm's.
In The Rocketeer, Jenny Blake greatly admires film star Neville Sinclair until she finds out he's a creep and a Nazi spy.
In Transformers: Dark of the Moon, Optimus reunites with his mentor Sentinel Prime, who was believed to have been lost in Cybertron's final battles. Optimus, with all due respect, offers Sentinel back the Matrix of Leadership, but Sentinel declines, saying that Optimus knows more about the human world than he does. It's later revealed that Sentinel has sided with Megatron, compromising the beliefs he taught Optimus in order to ensure the survival of the Cybertronian race. Optimus, after recovering from his shock, battles Sentinel, eventually executing him with (the now dead) Megatron's fusion shotgun.
Sean to Mark in The Social Network. Mark admires Sean's power and ideas but his faith wavered when he finds out about Sean's arrest for partying and doing drugs with under-aged interns.
In the 1980 John Ritter movie Hero at Large, Steve Nichols becomes a national hero for foiling a robbery while dressed as Captain Avenger. But when a reporter announces that the last robbery he foiled was staged, specifically to make him look like a hero, the crowd turns on him.
Senior narcotics officer Alonzo Harris to rookie cop Jake Hoyt in Training Day.
The Dark Knight Rises: Robin John Blake is an idealistic young cop, whom Commisioner Gordon quickly promotes to Detective, seeing something of himself in Blake. Blake looks up both to Gordon (for being an honest cop who cleaned up the department) and Batman (whose identity he figures out pretty quickly). However, he ends up being disappointed in both: at Batman for his Refusal of the Call, and at Gordon after finding out that Gordon lied about Harvey Dent.
Harvey Dent become this to the entire population when Bane exposes his rampage eight years ago. With the White Knight's reputation in the gutter, it doesn't take long for the population to start, in Joker's own words, "losing their minds" as they simply give up on everything and start to riot when Bane encourages them to do so.
In Iron Man 2, Whiplash sets out to invoke this trope among the public regarding Iron Man.
Randy Robinson in The Wrestler is this to his daughter, Stephanie. After disappointing her by missing out on his promise to have dinner with her, is abandoned by her for the final time with no chance of forgiveness, which leads to his final journey to self-destruction.
In Cloud Atlas, Zachry and his people worship a goddess called Sonmi. It comes as a shock to him to learn that Sonmi in fact was a human being.
In Trick Or Treat, Eddie, the protagonist was a fanboy of the film's Big Bad, Sammi Curr, who gradually shows his true colors over the film. When Eddie tries to break off contact with him, we get this gem.
You got to be loyal to your heroes...they can turn on you.
In A Pure Formality, the inspector is a huge fan of the French author Onoff. His admiration comes to an end when he meets the author, accused of murder, in person in his office.
"It is me, your grandfather!" "I buried my grandfather." Ichiro and Mariko, respectively, later on in The Wolverine. Right before she stabs him in the throat. Also, Yukio's look right before the latter did it suggests that she felt disappointed realizing what kind of a person the man who saved her life is.
Jake: "It's all your fault! I used to see you as a hero, Elfangor. A leader. But the truth is you just couldn't see another way out! You sentenced us to hardship and pain and suffering. We were just kids! You made us question every value we had ever learned! You had no right to heap that weight on us, huge and impossible. You used us!"
Andalites in general for all of the kids.
The Dresden Files: Ebenezar McCoy took Harry in after he used magic to kill his evil mentor, and taught Harry all about how magic comes from human life, and how using it to kill perverts its very purpose. Which makes it all very ironic when McCoy turns out to be the Blackstaff, the one member of the White Council allowed to use magic to kill. In fact, the very reason Harry was paired with McCoy was so that someone could take him out if it happened again.
Subverted in that he's not terribly happy about it, and dislikes the role. Harry still doesn't take it very well.
He mostly gets used to it. Eventually.
The Fault in Our Stars: Both Augustus Waters and Hazel Grace love and are obsessed with the book An Imperial Affliction by Peter Van Houten. Augustus uses his one wish to take Hazel to meet Van Houten in Amsterdam. Unfortunately He turns out to be a total cynical Jerkass, not the wise and poetic writer they'd imagined him to be when they read the book. This is because he lost his daughter to cancer, and it is implied that Hazel painfully reminds him so much of his beloved daughter.
Harry's father James. In Harry Potter and the Order of the Phoenix, when Harry gets a glimpse into the past, he sees his father as a young man and finds out that he used to be a Jerk Jock. Sirius and Lupin do concede James was an idiot, but add that he grew out of it - which, considering that James died in an Heroic Sacrifice to try saving Lily and Harry from Voldemort, is true as well.
Dumbledore himself experienced this with Grindelwald, especially since Word of God's revelation and Deathly Hallows implying that there was more to their friendship, at least on Dumbledore's side.
The dad in The Night of the Hunter, who is hanged for robbing a bank around the beginning. And Uncle Bertie, who for all his talk of being there to help, is uselessly drunk the moment something bad happens. And Harry Powell, although we learn he's a Serial Killer before his fans do. And, if you look carefully, you can see that Rachel Cooper is too proud of her parenting skills to realize that her foster-children are in dire need of attention lest they go crazy.
A Series of Unfortunate Events: While nothing decisive is explicitly revealed, it is hinted in the last two books that the much-revered Baudelaire parents were involved in the murder of Olaf's parents.
In The Secret History, Julian Morrow's students look upon him as a divinity. By the end of the book, however, Richard sees his characteristic warmth and kindness as a mask for his essential lack of concern for his students or insight into their lives.
The main character is this for a whole lot of people in The Death of the Vazir Mukhtar, as he seems to have made a complete Face-Heel Turn from writing an incisive social satire to seemingly becoming one of the characters he has satirised. He realizes this too, though it's technically all rather more complex than that.
The Vorkosigan Saga features several of these, as Miles' generation encounters the fallout of some really horrible things done of the previous generation. Major examples include Miles and Elena learning about Sergeant Bothari's mental instability and the atrocities he committed while working for Admiral Vorrutyer in Warrior's Apprentice, and Emperor Gregor's depression and self-destructive behavior in The Vor Game when he first learns that his father Prince Serg wasn't the hero Barrayaran history makes him out to be, but rather whose death in a botched invasion was the best thing that could have happened to Barrayar.
The series also features a major inversion. Mark had been made to believe in his parents'note The parents of the person from whom he was cloned, to be precise— in-universe, at least on the mother's home planet of Beta Colony, it's considered the same thing alleged tyranny. (His father is undeservedly known far and wide as "The Butcher of Komarr.") Then he meets Aral and Cordelia and they're kind, loving, genuinely good people rather than what he's been led to expect. Because he'd built so much of his identity on opposing their supposed evil, the shattering effect on his worldview is just as severe as if the trope had been played straight.
In the early Sweep books, Morgan looks up to Selene Belltower after she discovers she's a witch, admiring her power, her reputation, even the way she makes her own essential oils (for spell ingredients). Then Morgan discovers what Selene really wants from her...
Subverted in The High King, the final book of the Chronicles of Prydain, when Taran is horrified by Prince King Gwydion inviting him to share in the treasures of Annuvin. Luckily, a tiny Glamour Failure is enough to make Taran quickly realize that it's not really Gwydion but Arawn Death-Lord in disguise.
I returned to the saloon, fearing and yet hoping to see Captain Nemo, wishing and yet not wishing to see him. What could I have said to him? Could I hide the involuntary horror with which he inspired me? No. It was better that I should not meet him face to face; better to forget him. And yet—
Sisterhood Series by Fern Michaels: Played as straight as an arrow with Henry "Hank" Jellicoe, owner of Global Securities. In Game Over, the Vigilantes and the Big Five, particularly Charles Martin, look up to Hank and think he's the best there is. Cross Roads ends up having them lose their respect for the guy, and Charles was just upset that his friend could possibly pull a Face-Heel Turn. Deja Vu goes further and makes it clear that Hank was Evil All Along, and that it's only now that the disguise has worn thin, and nobody can deny it any longer.
Jason Black to Hayleigh Griffin in Fat. Hayleigh is harbouring a massive crush on Jason, based on tv interviews, his music and magazines for teenage girls. Jeremy arranges for them to meet while she's in the hospital. Unfortunately, Jason is coked up to the eyeballs the entire time and hasn't washed in at least a week. This freaks Hayleigh out somewhat, but is actually the turning point for her, as getting over her crush on Jason is what triggers her recovery.
In A Song of Ice and Fire, Daenerys Targaryen suffers this when she learns from Barristan Selmy that the stories of her father being "the Mad King" weren't just lies. In a similar vein, Cersei Lannister's view of her father Tywin was broken when she found a dead prostitute in his bed. She had always believed her father was above sleeping with prostitutes, and desperately grasps at alternative explanations for her presence.
Minor, but present in The Mark of Athena, of the Heroes of Olympus series. Hazel, who looked up to Jason as a fair and capable leader, is enraged when he votes against rescuing her kidnapped brother Nico because he thought his behaviour suspicious. Everything is soon settled.
Later in that same book Jason and Piper encounter Hercules, who seems a decent guy at first, but soon turns out to be a world-class jerk. Piper calls him out on it. Hercules' pedestal has in fact been crumbling since The Titan's Curse when Percy realized that Hercules was the one who betrayed Zoe Nightshade and ruined her life.
In the first book, Into the Wild, the main character Fireheart puts Tigerclaw/Tigerstar on a pedestal. Then he finds out that Tigerclaw is a team-killing psycho, and they become arch enemies.
In the Tigerstar and Sasha manga Spin-Off, Sasha is in love with Tigerstar until she finds out about his evil actions.
In the Omen of the Stars arc, all of the Dark Forest apprentices except Breezepelt and Redwillow eventually have this when they realize how evil the Dark Forest is.
Jagged Peak from Dawn Of The Clans used to look up to Clear Sky, his older brother, until the latter kicks him out of the forest for having an unhealed broken leg. The pedestal crumbles to dust when Clear Sky starts bullying him in front of Gray Wing, causing Gray Wing to defend their brother and Jagged Peak to call him out on his behavior.
In Seven Days in May, Colonel Martin "Jiggs" Casey is a Marine who finds out that his CO, General James Scott, is heading a conspiracy to initiate a Military Coup and overthrow the President. In The Film of the Book, Casey also gets a nice Shut Up, Hannibal! moment when General Scott demands "Are you familiar with who Judas was?" when his part of the conspiracy is unmasked:
"Yes, I know who Judas was. He was a man I worked for and admired until he disgraced the four stars on his uniform."
In Protector of the Small, King Jonathan breaks his pedestal for Keladry when he accedes to Lord Wyldon's demand that she be admitted as a probationary page, despite the fact that there was no such provision attached to the law allowing girls to train for knighthood when it was signed ten years ago.note Keladry is the first girl to try. It gets worse when she learns that he stopped his daughter from becoming a page, making Keladry one of the few female Tortallan characters who never loves King Jon. (Later she comes to understand the political necessity of such decisions, but that doesn't mean she likes it.)
Averted in Ciaphas Cain THE HERO OF THE IMPERIUM. Cain's actions continue to make him a galactic hero, despite each of them being motivated by cowardice and self-preservation. The only people who ever saw through it are an Inquisitor, who doesn't mind, and possibly a commissar cadet who dies anyway.
In Martin The Warrior: Felldoh was a slave all his life, Brome completely innocent towards the evil in the world looked up to Felldoh as an older brother and a badass. Yet as the story goes on, Felldoh becomes darker and obsessed with killing in his quest for revenge against the slavers. To the point where Brome didn't even know who he was anymore, he hated what Felldoh became to the point where he vowed to be as un-Felldoh-ish as possible by becoming a complete pacifist.
A Mage's Power: Eric idolized Dengel ever since he read the ancient mage's book, "The Spirit and It's Power". After he becomes a Heroic Host for Dengel, he exclaims that he keeps that book on his bed side table. Then he pulls a Grand Theft Me and Eric realizes that he's a treacherous and power hungry opportunist.
Miss Fisher's Murder Mysteries: Georges Sanderson to Jack, in the second-to-last episode of the second season.
Sara's best friend, a prosecuting attorney, is confined to a wheelchair — ostensibly shot by an unknown man who killed her husband. When Sara reopens the investigation, she learns that there was no intruder — her friend was the one who shot her husband. (Sara doesn't quite use the stock dialogue, but does point out the hypocrisy the attorney has been demonstrating in her demands for justice.)
Catherine discovered that the cop who inspired her to become a CSI rather than a stripper had planted evidence in a homicide investigation. (Pithy statement: "Good evidence doesn't need help.") She points out that he threw away his integrity, which is the thing that he himself taught her that you can never give up.
Warrick's mentor lost it after the murder of his daughter and assaulted the suspect, who turned out to be innocent. (Pithy statement: "An eye for an eye and the whole world goes blind.")
Oddly enough, the trope was subverted in this show as well. The episode revolved around the murder of a psychic; one of Brass's buddies, on the verge of retirement, showed up saying that he had been consulting the psychic regarding a cold case he has been pursuing, and that his suspect murdered the psychic to stop her from providing the location of the body. The suspicion is raised that the old cop is trying to frame his suspect, but he turns out to be completely legit.
CSI: NY gets in on the action as well, although they play around with it a little. Flack's mentor and friend is found to have tampered with a crime scene in order to protect his son, who was present when the murder took place. The mentor is arrested, but Mac is the one driving the investigation; Flack is pissed to have to go after a friend and remains bitter about the incident for some time.
Jack Bauer, on 24 has seen this happen with two of his mentors; Christopher Henderson, who brought him into CTU, first turns out to be embezzling assets seized by the government and later becomes the point-man for a conspiracy that kills an ex-president and several of his best friends.
James Hellar, the Secretary of Defence, is probably the show's first Benevolent Boss and someone that Jack admits he "looked up to like a father". The pedestal gets broken over the course of three seasons as Hellar fails to live up to Jack's high standards: he obtains evidence against the President Evil but tries to use it for political leverage, he leaves Jack to rot in a Chinese prison for two years, and generally treats him like a mindless disposable resource. His remarks on Jack being "a curse" to everyone around him are particularly harsh, if more than a little true. There's the minor complication of Jack being in a relationship with Hellar's daughter...
No one on 24 can ever manage to retain their original loyalties throughout a season. Including Bauer himself.
Subversion: Former Special agent Mike Franks, NCIS, mentor of Agent Gibbs. Something of a jackass, but a Jerk with a Heart of Gold, though a very small heart of gold and a HUGE jerk. Some of Gibbs's more notable mannerisms came from him, but the main difference is he retired, Gibbs didn't (not permanently, anyway).
Happens retroactively in the Star Trek: The Next Generation episode "The Pegasus". The eponymous starship was Riker's first post-Academy assignment. The ship's former captain (now an admiral) was conducting illegal cloaking-device experiments until the crew mutinied. Riker defended his captain, and helped cover up the truth later. When said admiral comes back to retrieve said device, Riker admits that, given a second chance, he would have joined the mutineers instead (a claim he gets to fulfill in spirit later on).
Riker: I wasn't a hero, and neither were you! What you did was wrong, and I was wrong to support you, but I was too young and too stupid to realize it! You were the captain; I was the ensign. I was just following orders.
In Star Trek: Deep Space Nine, we get Admiral Leyton, whom Sisko admired... until he tries to usurp power and declare martial law.
Then we learn that Odo had not always placed justice first and 3 innocent Bajorans were executed as a result.
And Admiral Ross works with section 31!
And in "Valiant", Nog meets Red Squad, the elite Cadet group from Starfleet (whom he adored) and they are stubborn, hubris-filled and intolerant, and get themselves killed, with Nog, Jake and some girl barely escaping.
Sisko gets to play the role himself once, to the audience. The entire episode uses a Framing Device of a log over the past week or so. During this week, he lied, broke laws, and was an accessory to murder in his quest to bring the Romulans into the Dominion War on the side of the Federation.
An in-universe example, Kor (one of the Original Klingons) joins Worf and General Martok on a raid in Dominion space. He is able to captivate the crew with tales of fighting the Federation. However, during the battle with the Dominion, when command falls to Kor, he believes he is fighting the Federation with his long-deceased friend Kang. This nearly destroys the ship.
Law & Order: Criminal Intent: Goren doesn't find it especially hard to believe that his FBI profiler mentor might also be the Serial Killer who kidnapped his partner. The twist reveals the killer is actually the profiler's daughter, who washed out of the FBI and wants to disprove her father's theory that women can't be Serial Killers (let's just say he couldn't leave the shop talk at work and she liked to use his recordings of people being tortured as a test for prospective high school boyfriends before getting intimate with them) in a desperate bid to get his attention. Needless to say, it worked.
Then, in a later episode, said mentor helps Goren's archnemesis kill his younger brother, and then kills her himself, in order to become closer to Goren. Goren doesn't understand it either.
In Chuck, Casey's mentor comes back and is a Fulcrum agent.
Also, Chuck's old college girlfriend turned out to not only be a spy, but also a Fulcrum agent. In all honesty it seems like everyone in any way connected to Chuck is involved with Fulcrum in some way...
Not exactly. Nowhere in the episode is it stated that Ty Bennett was working for Fulcrum, and he is instead set up as having instead been working independently and forming his own mercenary/terrorist organization. It's revealed in a later episode in which Casey is reunited with his former commanding officer—another Broken Pedestal who is now working for the Ring—that Bennett was actually working directly with or for him.
Daniel Shaw makes for one huge Broken Pedestal. Set up as Chuck's mentor in using the Intersect, and a great spy and everything Chuck was aspiring to become once accepting his destiny as a hero (YMMV how well this was played). Then he gets manipulated, broken, and turned by the Ring to become one of the most dangerous villains in the entire series. Only Quinn in the fifth season came close to hurting the team as deeply and personally as Shaw did.
In Bones, Brennan's old professor, whom she had and currently was dating, was an expert witness for the opposing side of the case she was working on. To specify, he's not doing it in service of the truth, which Brennan would respect him for, but because he's being paid to do it. Then he implies, on the stand, that she's not an objective researcher even though he and the scientific community recognize Brennan as the best and most objective in her field. He is also outright lying, since he had previously called Brennan's case irrefutable, meaning everything he said about other possibilities was wrong and he knew it. In the end she dumps him via a What the Hell, Hero? moment.
Brennan: This one isn't about winning a pasta dinner or showing up your former student. It's about putting two people away who murdered a 19-year-old girl.
Michael [the professor]: Tempe, you can't personalize the work.
Brennan: Do you remember in Central America standing in a mass grave being guarded by soldiers? We knew that they were probably the same soldiers who had killed the people we were digging up. I was just a student. I was scared. I turned to you and I asked, "What do we do?"
Michael: That was a different place and a radically different context.
Also Brennan's brother, who left her shortly after their parents were forced to flee their past. They reconcile later.
Scrubs does this a lot, usually JD reversing one of Dr Cox's pieces of wisdom back on him. Though Cox was a dick from day one.
Subverted, however, in the episode My Fallen Idol, where JD convinces himself that he's furious and disgusted with Cox for being a hypocrite about the advice he gave JD in the previous episode "My Lunch" after accidentally killing three patients, and then coming in to work stinking drunk the next day. However, JD gradually realizes that he actually doesn't care about what Cox did at all, and in fact admires the fact that even after years as a doctor, a patient's death could still affect Cox that deeply — he was just terrified over the idea of his tough, unshakable mentor being so badly shaken, and was using the things he did as an excuse to avoid him.
In a sketch on Little Britain, Sebastian (in love with his boss, the Prime Minister) is asked to destroy some secret papers which reveal that the Prime Minister reneged on a disarmament pact. Sebastian obeys, but sadly whispers "I thought you were perfect ..."
Dexter's gone through a lot of these. He idolizes his foster father Harry, adhering rigidly to the "Code of Harry" when he kills, only targeting criminals who've escaped justice, and never taking risks of being caught. Then, in Season 1, he finds out Harry knew Dexter's biological father was alive and kept the info from him, and destroyed the file on Dexter's Harmful to Minors moment. If that's not enough, in Season 2, Dexter decides to abandon the Code-or at least shift it to suit his means-when he finds out that Harry likely killed himself because he couldn't stand what he'd made Dexter into. He also had an intimate relationship with Dexter's birth mother, which was directly responsible for her murder.
In season 6, Dexter meets the man who inspired him to be a serial killer-the Tooth Fairy, a man who ripped the teeth out of his victims, and once dumped a fresh body on a District Attorneys lawn and still managed to elude capture. He's become an abusive, drunk old pervert waiting to die in a retirement home. Granted, its not like we'd expect much more from a serial killer, but the impact it has on Dexter certainly shows elements of Broken Pedestal.

Conan: Tell us about this scene. This is a fight scene?
Dean the Foley artist: Yes. This is between two principal characters, Chris Meloni and James Brolin. Chris Meloni just found out that James Brolin, who is his mentor, actually killed someone.
Conan: They always do. Mentors always disappoint, just as you've disappointed me today.
Monk: Though not quite a mentor, a child actress from Monk's childhood favorite TV showthe only TV show he ever watched and the only thing that made him happy as a child ("'The Cooper Clan' was my other family. Heck, the Coopers were my family, my family was my other family") wrote a tell-all memoir about her very sordid life and the lives of her costars. There wasn't enough Brain Bleach to help Monk after reading it...
In season 3, episode 8 of BBC's Robin Hood series, Robin's mentor appears, having agreed to help Prince John fake out the people of Nottingham with a lifelike wax dummy of King Richard, pretending that he's died. His reason for treason falls to Never Remove a Blood Knight From The Battlefield.

Variant: On Top Gear, when James May and Richard Hammond get to drive their childhood dream vehicles (a Lambourgini Countach and a Vincent Black Shadow motorbike, respectively), they find that the real things are harder to drive and less comfortable than they had imagined.
May: And [the Countach] looked so good on the poster. In fact, I wish it had stayed there. I'm absolutely gutted. But you know it's not the car's fault; it's mine. I've broken the Golden Rule: You never, ever meet your childhood heroes. ...Stick with the memories. They're just better.
A minor version appears in the Doctor Who episode "The Shakespeare Code". The Doctor and Martha Jones attend the premiere performance of "Love's Labours Lost" and Shakespeare himself appears on the stage at the end. The Doctor is initially thrilled at the prospect of meeting the greatest writer in the English language—until he acts boorishly in front of the audience. Somewhat amused, Martha quips to the Doctor, "You should never meet your heroes."
It gets even worse when he starts (quite unsuccessfully) hitting on her.
Played with in terms of Rose's affection for her dad, Pete. Since he died when she was a baby, he was built up by Jackie as being the perfect father- so when she travels back in time to his death, only to find that her parents were having marital problems, Pete was failing as a businessman and liked flirting with other women, she was upset. However, in the end, he proved to still be a good man; incredibly devoted to his wife and daughter, and willing to sacrifice his life to save others.

The Doctor goes through this when he meets Omega, one of the first Time Lords who apparently died giving the Time Lords the power source of time travel. Omega survived and is trying to drain away the Time Lord's power, driven mad by millennia of isolation.
At the end of audio drama "Zagreus" the Doctor says this has happened with all his Time Lord heroes, Omega, Borusa, Morbius and Rassilon.
Played a bit straighter in other situations, usually involving the Peacekeepers:
Captain Durka was a legendary figure among the Peacekeepers, and his ship, Zelbenion, was rightly feared throughout the Uncharted Territories. Then it's eventually learned that Durka was actually a coward and probably psychotic as well, faking his own death and surrendering to the Nebari when they attacked his ship.
A later episode has Sub-Officer Dacon, a legendary Peacekeeper officer who sacrificed his life to safely end an assault on a monastery filled with nothing but women and children. When the crew gets accidentally sent back in time to this event, turns out Dacon is just a cook. He is a decent person though, and it turns out his commanding officer was the real hero of legend, so there's that.
Shawn and Gus from Psych see a bounty hunter (played by Hercules) bringing in a thug in the prologue of "Bounty Hunters" (season 2 episode 9), and immediately decide he's the coolest thing on the planet. Then he turns his head and winks at them, taking a level in awesome, and the Hero Worship begins in earnest. Years later (i.e. later that same episode) they meet him again and it turns out he's a complete douche, the "wink" was just a tic, and he even tries to kill Shawn and Gus near the end of the episode.
The episode "Fallen Idol" of Mash. Hawkeye has to leave the O.R., due to a hangover. This breaks the pedestal Radar (and, according to Radar, many others as well) has put Hawkeye on.

The detective who taught Beckett everything she knew though she did chase his killer to Los Angeles
Castle's old school friend who inspired him to be a writer.
The cast of Nebula 9 (a Star Trek clone), specifically Captain Max Rennard and Lieutenant Chloe, for Beckett. She used to love the show (which only lasted 12 episodes) despite the cheesy premise, over-the-top acting, and awful-looking aliens and cosplayed as Lieutenant Chloe. Then, while investigating a murder at a 'con, Beckett meets the actors playing them. Rennard's actor is a pompous Jerk Ass and a washed-out actor who can't get a decent role and seems to think he really is Captain Rennard. Besides acting the "Nebula 9 Experience" to ridiculous extent, he tries to pick up any woman in the vicinity. Chloe's actress is a bitch who hates being type-casted because of the show and turns out to be the killer, trying to prevent the revival. Despite this, Beckett resolves not to let her affect her memories of the show. After all, her idols were the characters, not the actors playing them.

Supernatural - God himself. Castiel, a steadily descending angel spends most of season five looking for his father for guidance on how to prevent the apocalypse, only to discover that God just doesn't give a damn about any of them anymore, has effectively left them alone to get on with it, and doesn't care whether the apocalypse happens or not. This does not have a good effect on Castiel.
Castiel later becomes this to the Winchesters and the angels who follow him in the Angelic Civil War after it becomes clear that he has become a ends-justify-the-means Well-Intentioned Extremist and is making deals with demons.
Metatron invokes this when he positions Castiel to become a leader again during the Second Angelic Civil War, only to then frame Castiel as the mastermind behind a series of suicide bombings. The undecided angels respected Castiel for stopping the Apocalypse and thus flocked to him until Metatron's scheme showed them Castiel's flaws. Disillusioned, Castiel's followers switch their allegiance to Metatron. Castiel then turns it right back on Metatron by showing Metatron's most loyal followers what a Manipulative Bastard Metatron really is.
Buffy has moments like this with Giles, although she usually eventually gets over them. Until she doesn't.
Buffy: Yep. I thought you were a grownup. Now, it turns out that you're a person.
Giles: Most grownups are.

On Heroes, Hiro grew up being told of the legendary samurai warrior Takezo Kensei and his incredible battles against evil.

From Merlin, Arthur is a huge "Well Done, Son" Guy who's basically spent his entire life having it hammered into him that whatever he does, his father Uther does it better.

ER did an arc about Drs. Benton and Carter being taken under the wing of the illustrious Dr. Vucelich, the only doctor at County General to have never lost a patient. This is because he's a slimy cheat who drops every patient he knows is going to die from his care ahead of time.
Walter White from Breaking Bad has progressively become this more and more for his protege and partner-in-crime, Jesse, over the course of his slide into evil, as Jesse becomes more and more troubled and guilt-ridden over his actions and what Walter orders him to do. It seems to reach a head after Walt's rationalization over a child's murder and seeing through his manipulations. But it has finally culminated in him figuring out that Walter had Brock poisoned.
Played with on Frasier; after discovering that his mentor and Roz are having a relationship, Frasier believes he's experiencing this (and it's not helped by the fact that he saw his mentor wearing nothing but Roz's robe) but he comes to realize that it's actually jealousy that Roz has become attracted to someone very similar to him whilst having never demonstrated any kind of attraction towards him.
Roz: Frasier, did you ever stop to think there may be something special about not being picked?"
Frasier: Roz, that didn't work when I was cut from pee-wee football, it's not gonna work now.
Kamen Rider Gaim has a self-inflicted version of this: Micchy starts off the series viewing Kouta as the big brother he never had. Unfortunately, then they get caught in Triang Relations: both Kouta and Micchy like their teammate Mai, but she obviously likes Kouta. As a result, Micchy starts gradually changing his view of Kouta, viewing him as a naive idiot whose idealism only causes trouble. This leads to Micchy pulling a full Face-Heel Turn, complete with shooting Kouta in the back in the middle of his Rider transformation.
Brooklyn Nine-Nine: Peralta is initially thrilled to meet his idol, reporter Jimmy Brogan, who wrote a true crime novel about 1970s New York cops that inspired Peralta to become a cop.

Mighty Morphin' Power Rangers had this happen in the episode "Rita's Pita." One of Tommy's karate students, Danny, looks up to Tommy. That is until Rita plants a monster inside Tommy's stomach that makes him crave nothing but junk food.

When Tommy gets the monster out of him, he apologizes to Danny for the way he acted and Danny's respect for his teacher returns.
The Who's Quadrophenia brings us the Ace Face, a mod whom Jimmy, the album's protagonist, idolized during the Mod days. When he meets him later, he finds that he's sold out and is now a bell boy. The whole album is about Jimmy being let down by his idols.
The Phantom of the Opera: 'Farewell my fallen idol and false friend/We had such hopes but now those hopes lie shattered...Angel of Music, you deceived me/I gave you my mind blindly.' Erik goes from being a Stalker with a Crush into a full-blown wack job when he, in a convoluted Wife Husbandry plan kidnaps Christine and threatens to kill her fiance unless she agrees to marry him (Erik, that is).
Subverted with the protagonists' relationship in Wicked, as Elphaba and Glinda, who sing about how "People come into our lives, for a reason," genuinely feel that they have been changed for the better for knowing the other, even though Elphaba has turned her back on society, and Glinda has sold out to the love of the citizens of Oz.
Wicked also contains a straight example in the Wizard, beloved by all of Oz and idolized by Elphaba and Glinda, who turns out to be a con man and the Big Bad. Though the revelation takes longer for Glinda to process, she eventually accomplishes more with the knowledge than Elphaba.
Arthur Miller's All My Sons revolves around this trope after The Reveal.
Death of a Salesman: Biff, the elder of the two Loman sons, is the high school football star and pretty nearly guaranteed a full scholarship to the University of Virginia...until his Broken Pedestal moment. He gets into a scrape at school and goes to find his father, the eponymous traveling salesman, with the hope that his father can get him out of it. The result is that he discovers his father is a serial philanderer. He's so disillusioned by the fall of his idol that he ends up dropping out and throwing away his very promising future.
The Nerd by Larry Shue.
Assassin's Creed: Your mentor Al Mualim turns out to have been sending you on missions the entire time to distract you from his plot to use a mythical object to mind control all of the assassins, his allies.
In Assassin's Creed III, Connor eventually learns that George Washington and not Charles Lee was behind the razing of his village Kanatahséton and thus the death of his mother — and just ordered a new attack on it, to exterminate his people and salt the earth. Although Connor isn't fooled by how thick Haytham lays on the disdain, Connor's relationship with Washington never really recovers even after he prevents the attack by killing off Washington's messengers.
Sanchez of Suikoden is an excellent example. A part of your army since the very beginning, it eventually turns out he was a spy working for the enemy the entire time, and when the Empire is close to losing he gets desperate and fatally injures your army's chief strategist. The icing on the cake and what makes the situation relevant is that your faction ultimately decides that the newly-formed government could not withstand the scandal of one of its founding members turning out to be a traitor the entire time, and he lives out the rest of his life peacefully under a secret house arrest. Publicly speaking, his image as a hero is never tarnished.
A subtle hint is provided since the castle is founded: if you took the time to look at the massive tablet that has the 108 stars and people's names, you'll notice he's not on the list. You'll also notice he is the only one living in the castle who's not on the list.
Van Grants for Luke, Tear and Guy, Legretta for Tear, possibly Ingobert for his daughter Natalia; the two ultimately reconcile after the truth comes to light, but Guy suggests that they can't necessarily go back to the way they were before.
Interestingly enough, Legretta, in a final letter read after her death, mentions feeling concerned that her student Tear saw her as an ideal, and hopes that Tear will follow her own path, a rare case in which the character on the broken pedestal attempts to dispel the admirer's notions.
Also, The Emperor for his daughter, Sun Lian/Silk Fox. Even the revelation that Master Li is the Big Bad and the root cause of the plan to usurp the Water Dragon's power does not absolve him in his daughter's eyes.
Master Li is not only the Broken Pedestal for the Player Character but also for Dawn Star, especially when she finds out he's her father who doesn't give a shit.
Happened in Castlevania: Order of Ecclesia. Turns out Barlowe is a Dracula worshipper and uses the organization and Shanoa as a tool to revive Dracula. Depending on how the game is played, Shanoa may end up following him blindly (and dying in vain), or wises up and performs a Rage Against the Mentor.
Frimelda Lotice in Final Fantasy Tactics A2 had this happen to her. She was revered as a powerful Blademaster, and fought alongside her friend Luc Sudarc in many battles. She, however, didn't know that Luc was hugely jealous of her, as he just wanted to surpass her but couldn't no matter how much he trained. So, he poisoned her, sentencing her to wander Ivalice as a pink zombie...until Luso and the gang rescue her. They return her to human form with the help of a special potion, and to return the favor, she joins Luso's clan. And she's cute, to boot.
Arc The Lad 3. The main character becomes a Hunter because one saved his life when he was young. He later finds that Hunter working for the Big Bad.
Played with in Persona 4. After a major character is seemingly Killed Off for Real, the protagonist's surrogate father figure, a by-the-book and thoroughly incorruptible policeman, runs off apparently to kill the man thought responsible; this is part of a Batman Gambit on the part of the writers to induce the player to kill the suspect when given the opportunity, which is a one-way ticket to the Bad Ending. Later on, after having some time to chill out (like the player characters) he was able to see that the evidence surrounding him just didn't fit and wanted to just get some more info from him.
True Crime: New York City had Terry Higgins, a cop who helped Marcus from slipping off the slope; he is presumably dead early on. It was revealed he was The Mole and was quite corrupt despite how Marcus saw him. Marcus will either kill him immediately if his ethics are less than questionable or attempt to arrest him but Terry dying.
Subverted in Metal Gear Solid 3, in which we are initially led to believed that Naked Snake's mentor, The Boss, had defected to the Soviet Union. It turns out that the defection was a ruse to gain Volgin's trust and acquired the Philosophers' Legacy, but after Volgin framed The Boss for the destruction of Sokolov's Research Facility, alerting her presence to Khrushchev, the U.S. sent Snake to kill her and cover up her involvement. This essentially shifts the target of his broken bedestal moment from his mentor to his government. Increases even further in later games when it is revealed that the U.S. government fully intended to have Snake kill off The Boss from the very beginning regardless.
In the Fire Emblem series, this applies to (in Path of Radiance) Most of the Begnion senators, and (in Radiant Dawn) The god that most of the populace worshiped.
Disgaea 3 has Super Hero Aurum, beloved by humans (and some demons) and idolized by Almaz. By the end of the game, you discover that he has gone out of his way to make Mao into the most horrible villain imaginable, trying to manipulate him into attacking the human world, simply out of boredom from having no "worthy" opponents. And when this fails thanks to the Power of Friendship, even the demons of the party call him out for his blatantly villainous actions, with Mao declaring cowardly Almaz a far more superior hero than Aurum.
Tomb Raider (2013): Lara used to admire James Whitman, but by the time of the game has seen him for the narcissisticSlave to PR and Know-Nothing Know-It-All he really is. When she discovers a note to his soon-to-be ex-wife, in which he tries to convince her to wait until after the Yamatai expedition to divorce him largely because he wants to avoid negative publicity, she explicitly remarks she's disgusted with herself for ever having looked up to him.
In Star Wars: Knights of the Old Republic, Republic hero Carth Onasi was scarred when his mentor and idol, Saul Karath, turned out to be working for the Sith. He retains a deep mistrust of all Jedi, and the revelation that the player character is the amnesiac Darth Revan, former commander of the Sith rebellion doesn't help matters.
Mission's quest involves finding out her brother deliberately left her behind when he left Taris.
A Sith Warrior in Star Wars: The Old Republic invokes this trope when recruiting Jaesa. Jaesa is a gifted, but inexperienced Padawan who can "see" the true nature of others. Her master and Darth Baras (your handler) have a long-running feud. when confronting the old Jedi, you can force Jaesa to "see" her master has been hopelessly warped by his grudge, causing her to abandon him, and serve you instead. It is up to you if you want to keep her inclinations to the Light Side, or Break the Cutie by twisting her into a very psychotic verion of The Dark Side, however.
In The World Ends with You, Neku is a total CAT fanboy. Later on, he discovers that Mr. Hanekoma, a guy who's been real helpful to him, is the elusive CAT, and starts fanboying even harder. Then, in the final week, Neku discovers a lot of clues that suggest that CAT is the Composer, and goes through a textbook case of denial, then losing faith in CAT as they approach the Composer's chamber. Only, as Kitaniji tells him, Hanekoma is not the Composer. The very end of the game, plus the Secret Reports, however, tell you that he's still not someone to trust, albeit better intentioned than Kitaniji or Joshua.
In Viewtiful Joe, Captain Blue turns out to be one for Joe, after he reveals himself as the Big Bad.
However, After Blue has a Heel-Face Turn it seems Joe regains respect for him again.
Averted with Granas himself though. Whatever his nature his ideals were genuine and the only thing he was guilty of was coddling his followers far too much, stagnating independant human development (why bother innovating if your god can conjure starships out of thin air?). In the end, he died sacrificing himself to save his people.
In Baldur's Gate II, Jahiera has this in regards to the Harpers during her personal quest. First, Galvarey, the regional Harper leader in Athkatla turns out to be an opportunistic Smug Snake who wants to use charname in his bid for power. Jahiera is understandably dismayed by this, especially since the other Harpers, who are unaware of Galvarey's intent, consider the incident an act of treason on her part and a murder on your part. Once that is cleared up, she discovers that Dermin, her old mentor, was actually in on Galvarey's plot, and is just as much of a Smug Snake as he was. Needless to say, the whole affair shook Jahiera to her core.
In Guild Wars Nightfall, Varesh Osha is seen by many as an ideal ruler of her nation. Turns out she's a batshit insane worshipper of the resident Eldritch Abomination.
In Pokemon Mystery Dungeon Explorers of Sky, Wigglytuff's beginnings as an explorer are revealed. As a child, he met Armaldo in a deep forest. Armaldo told the then-Igglybuff that he was a retired explorer, and they went on lots of missions and found lots of treasure. Igglybuff idolised Armaldo and everything was going perfectly well...until Armaldo got arrested. He was a wanted criminal, not an explorer. Igglybuff almost had a mental breakdown and refused to believe that Armaldo was bad, even as he was being led away in custody. Whether they met again after Armaldo got out of prison is unknown.
And subverted. Armaldo really did care for Igglybuff and was curious to see how far he'd go as an explorer. Armaldo comforted Igglybuff and told him to continue exploring for him. And he promised to explore with him again once he did his time.
Present in Pokémon Black and White with N finding out that he's nothing but a brainwashed child soldier and that his father Ghestis is intent on banning Pokemon use so Team Plasma can "liberate" them all and use their power to conquer Unova.
Jacob Taylor's father, Ronald, vanished 10 years ago. When they receive a message and go to the unhabited planet to save them, turns out that after his ship crashed and the captain died, Ronald forced the lower crew members to eat the planet's toxic food, which caused their minds to degrade, while they tried to fix a beacon to call for aid. Female crew members were assigned to officers, like pets. A year later, the beacon was ready, but Ronald figured the report would look bad and wanted to stay. He then had the other officers killed. Gradually the degraded males started to rebel, becoming "hunters" as even in a decayed state they knew things weren't right. Ronald held out for ten years, until his supplies ran low and he called for aid. Needless to say, Jacob was utterly disgusted and would've killed his old man, if not for the fact he "wasn't worth pulling the trigger". If your Shepard is a renegade, you can suggest Jacob to give his father a weapon with one bullet. If you pick the neutral option, he will get killed by his own men.
And then there is Rael'Zorah, Tali's father and a part of the Admiralty Board. Her father is found dead on the ship and Tali was accused of treason. When she find out what happened, it turns out Rael'Zorah was willingly endangering his own crew's lives to create a measure to control the Geth much to her horror.
A few people, most prominently Ashley/Kaiden (even more hardhitting if they were your love interest in Mass Effect), consider Shepard to be one since s/he's working with Cerberus, a terrorist organization in Mass Effect 2.
Even before that, in the first game, you can make Shepard into one for Conrad Verner.
Through the first and second games, the Protheans have been regarded as a race of very advanced and powerful, but benign Benevolent Precursors. Then in the third game, we meet Javik, the last Prothean warrior, and find out that the Protheans were actually a highly imperialistic society who conquered anyone they encountered and integrated them into their empire as "subservient races." Liara in particular is quite disappointed, once implies that they were monsters, and comes to consider her earlier writings on them as foolishly naive.
Liara: You're a Prothean! You were supposed to have all the answers!
Given more time, she changes her stance a little, no longer feeling betrayed and able to think of them more objectively.
Liara gets another one when she finds out her own government has maintained their technological superiority by hiding a Prothean Beacon from the rest of the galaxy, in defiance of Citadel laws.
Cerberus becomes one for Miranda at the end of 2 and in 3.
Cloud got hit by this in Final Fantasy VII. As a teenager, he dreamed of joining the elite SOLDIER unit like his idol, the great warrior Sephiroth. When Cloud finally gets to go on a mission with Sephiroth, finding out that Sephiroth wasn't as noble as Cloud thought he was is the least of our hero's disappointments.
Infamous: Cole's girlfriend Trish breaks up with him when the Voice of Survival's Malicious Slander leads her to believe that Cole deliberately set off the Ray Sphere explosion that claimed her sister's life.

Then you find out about what he has done over the events of Dead Money where he used you to do his dirty bidding along with 3 others.
One resident of Megaton in Fallout 3 put the Enclave on a pedestal based entirely on their radio propaganda. When they actually show up, they rapidly break their own pedestal. Kidnapping said fan was probably the least evil thing they did in the game.
First Enchanter Orsino in Dragon Age II can become this to Bethany if she joins the Circle. If Hawke takes the side of the templars during the endgame battle sequence, they can get Orsino to admit that he protected the serial killer responsible for turning their mother into a Frankenstein bride. In the mage endgame, Orsino only mentions Quentin offhandedly and we don't see how either Hawke sibling reacts.
The "Legacy" DLC turns Malcolm Hawke into one with The Reveal that he was a Blood Mage. Probably the most sympathetic example of this trope ever since he did it to seal away a powerful evil, was forced to do it with a threat to his lover, and he made sure his mage child(ren) knew of the dangers associated with it. Malcolm was ashamed of his past and hoped his family would never learn of it. His children still don't take the news very well but understand why he did it.
The Grey Wardens can become this to Carver if he joined them, after learning that Warden-Commander Larius gave the order to blackmail Malcolm Hawke into performing Blood Magic, because they threatened to kill Leandra if he refused. Particularly as Leandra was pregnant with his older sibling at the time.
In Corpse Party Ayumi greatly respects Naho Saenoki, an occult expert despite just being in high school.

Ayumi calls her out on it. Naho doesn't really care and insults "occult freaks"...until Ayumi reveals that after Naho succumbed to The Darkening, she killed her beloved mentor, Kou Kibiki. She doesn't takethis revelation well.

When she tries to beat Red in a battle later to find closure, he ends up on a Rebuilt Pedestal and she declares her fangirlish love for him again. This does not please her newly acquired male fanbase.

In Injustice: Gods Among Us, Regime Captain Marvel, still a kid here, looked up to Regime Superman, even going along with his ideas of a better world.

Sadly, Regime Superman kills him before he can bail. However, it does inspire another to do so: Regime Flash.

However, Phelps was caught having an affair, causing everyone who held praises for him to hating his guts while he got demoted to Arson duty.
In Diablo, part of the reason why Farnham became The Alcoholic is the sense of betrayal he felt after Archbishop Lazarus betrayed him and the others to demons.
Mage Gauntlet has Whitebeard. The ritual to repair the Dark Realm seal requires sending a mage through the portal permanently, which is the ultimate fate of most of his apprentices. He only gave Lexi the gauntlet to make her an acceptable sacrifice. Furthermore, Hurgoth is merely a gatekeeper for much stronger creatures, and Whitebeard has been using his fame as an excuse for every kind of forbidden magical research in existence, ultimately getting one other mage turned into a lich, possibly getting another consumed by a slime hivemind, and creating an entire army of walking body horror.
In Phoenix Wright: Ace Attorney, prosecutor Miles Edgeworth discovers that the man who raised him after his father's death (and taught him everything he knows about law and prosecution) is his father's killer. And also a ruthless perfectionist who'd do anything to win, but he already knew that.
In another example for Edgeworth, he finds out that Ernest Amano, who financed his studies, and whom he respected enough that he would deliver the ransom money to his son's kidnappers as a personal favor, obstructs justice by buying the haunted house in Gatewater Land so that his son won't be exposed as a murderer, and is also affiliated with the smuggling ring. The closest he gets to a pithy statement is saying in the ending that he owes him a debt of gratitude, but he must pay his debt to society.
Kristoph Gavin, the mentor of Apollo in the fourth game ends being the murderer in the first case and the Big Bad of the game. Apollo is also livid to find out that Phoenix, a former ace lawyer whom he treated with the utmost respect, gave him a fake clue to make Kristoph confess to the murder of Shadi Smith, to the point of punching him. He only comes to work for him because with Kristoph's arrest, he's out of a job.
Damon Gant was the well respected chief of police. It turns out that He murdered an innocent man in order to frame a serial killer and years later killed a cop who was trying to find out the truth and let someone else take the blame for it.
Ema also has this reaction when her sister admits to forging evidence, although it later turns out that she was blackmailed into doing so by Gant, who had arranged evidence to make it seem as though Ema accidentally killed Neil Marshall.
Morgan Fey for Mia and Maya, who both loved their aunt and are upset to find out that she would try to frame Maya for murder out of jealousy, so that her daughter Pearl could become Master.
The killer was planning to invoke this trope in the second case of Dual Destinies. The reason why Florent L'Belle didn't kill Mayor Tenma as part of the plan to frame him for murdering Alderman Kyubi was so that once Mayor Tenma was convicted and exposed as the true identity of the Amazing Nine-Tails (the hero that everyone who opposed the merger rallied around), the Amazing Nine-Tail's popularity would plummet once people realized he was also a murderer.
In Investigations 2, Blaise Debeste becomes this for his son Sebastian after it's revealed that he's the killer in case 4 and that he never really cared for Sebastian in the first place.
In Dangan Ronpa, Mondo Oowada is this for Kiyotaka Ishimaru. At first, he refuses to believe that Oowada was the murderer of Chihiro Fujisaki in the second case, but then he is forced to confront with the truth and the poor guy suffers a Heroic BSOD. What makes the whole thing more painful is that Oowada was the first real friend that he ever had, since he was never able to make friends due to his focus on studying and working on school morals.
During Hatoful Boyfriend, Sakuya only seems to have any respect for his father and Doctor Iwamine Shuu, the latter of whom developed a medicine that saved the former. He's extremely defensive about criticism to either. Sakuya has been raised to think of his father as "pure", of the utmost value and to be obeyed unthinkingly. Through his route he can come to disobey, but it's in BBL that things really change. He insists privately that "I must not disrespect him (Shuu)... because that is what father told me." but is unable to ignore mounting evidence. Eventually he despises Shuu just like everybirdie else.
Sluggy Freelance has an example of this when Torg finds out that Riff is working for Hereti-Corp, although as Riff mentally notes shortly afterward, he had no idea how they were using the information he was sending them. Torg ultimately forgives him by the end of the arc, noting the contrast between how he treated him with how he believed Cloney was actually Aylee.
In Kevin & Kell, Rudy is shocked to find out that his biological father had an affair that resulted in Rudy's nemesis Vin Vulpen being born; Kell suspected this but didn't know for certain. Lindesfarne, after learning that Professor Antlerhead falsified his research on stem cells, notes that the only authority figures who have never let her down are her father and stepmother.
Happens in Juathuur...sort of. actually, Arvval stands by his principles from beginning to end. But when Faevv strays from her path, his bigotry becomes apparent and they don't really get along anymore.
In Starslip, Holiday enters her crush object Vanderbeam's mind to try and free him from an alien Lotus-Eater Machine. There, she discovers his long-harbored obession with the long-dead Jovia and the lengths Vanderbeem is willing to go to to get her back (i.e. throw his support behind a former criminal to gain technology that might enable him to save her, knowing the criminal wants the tech to try and regain his former power). When Vanderbeam refuses to see reason, reaffirming his willingness to do whatever it took to save Jovia, Holiday simply, and sadly says "You have no idea how much of my respect you've lost. For good." Ironically, this is enough to snap Vanderbeam out of it.
Antimony Carver of Gunnerkrigg Court learnt in Chapter 31 that Surma, her mother, acted as the Court's Honey Trap to lure Reynardine into the court. When she tries to confirm this unpleasant truth ("So my mother...tricked Reynardine into thinking she loved him?"), Kat's mother tries to justify with the threat Reynardine posed if he were allowed to roam free.
Katerina Donlan is rather upset upon learning what the founders of the Court, where she has grown up all her life, did to Jeanne and her lover. It sure doesn't help that Diego, Kat's robot-building genius hero, came up with the horrifying plan, and did so purely out of spite and jealousy.
Bittersweet Candy Bowl has Alejandro, Paulo's original "coolness teacher," which was really just Paulo being messed with by the older kid.
In Slightly Damned the reader is lead to believe that Sakido genuinely cares for her little brother Buwaro. While it may be that way now, it turns out she is acting as The Atoner for maiming and abandoning him 15 years ago. Her final line, recorded in a journal, really hammers home how tortured she was on that choice.
"If you are reading this and I'm no longer around, then I've gotten what I deserved."
Following the media smear campaign and everything else in Sonic the Comic – Online!, Sonic has become this to the remaining Freedom Fighters and Mobius. Let's just say that, when you know the Sonicverse as a whole, it's pretty jarring to see even Amy hating Sonic; Tails is literally the only being on Mobius who still believes in him.
In the beginning of the story, Elan positively adores Vaarsuvius, to the point where Elan dresses as a wizard to try to be like him/her. However, after Therkla, a ninja who had a crush on Elan, dies, Elan is extremely upset and Vaarsuvius simply is unconcerned about it, caring more about the danger to the world for the quest they are on. V also disintegrates Kubota without knowing what Kubota did, and accuses Elan of cheating on Haley with Therkla when he expresses sympathy for Therkla's unrequited love for him. V's cruelty causes Elan to abandon him.
Miko Miyazaki had a very troubled life, being orphaned at an early age and raised in a monastery. She found comfort in serving the Twelve Gods and Lord Shojo, serving him even when he became old and senile. Hinjo, Shojo's nephew, serves his uncle, the only family he has left, just as faithfully When Shojo is revealed to have lied to them about his senility, the Gates, and working with Belkar Bitterleaf and Roy, just having found out an army of hobgoblins is on the way, Miko and Hinjo are both crushed. Hinjo reacts lawfully, by wanting to try Shojo after dealing with the hobgoblins. Miko takes a different approach, and cuts Shojo in half.
KateModern has Rupert van Helding, whose teachings are admired by so many in the Hymn of One. It's a shame he's such a hypocrite.
The Union Series has a Captain Evan Mc Neil, poster boy for much of the Colonial military. While made out to be a cheerful, war-is-an-adventure type paragon of soldiering, the hard reality recruits are confronted by is that he is truly a tired, run down man, aged beyond his years, who's spent most of his adult life being flung from one incredibly bloody conflict to the next, with only the sincere desire that someone will get lucky and put a bullet through his head to end his misery.
Red vs. Blue has Agent Washington in regards to the Director of Project Freelancer. When first introduced, Washington is highly against the Director and is actively working to bring him down after seeing the horrors the Director inflicted on the Alpha AI. Season 9 then shows a younger Washington, who is highly devoted to the Director and claims the man has given him everything.
Xandra from the Neopets story The Faerie's Ruin was a powerful witch who was taken to Faerieland to study. Initially, like the rest of Neopia, she believed that the Faeries were Big Goods, but the Faeries repeatedly refused to intervene in cases where she felt they should have. Feeling betrayed and deceived, she set out to break the pedestal for everyone else. She fucking crashed Faerieland into Neopia!
This trope is given an interesting dimension in the Pony POV Series. Ace flyer Spitfire has a breakdown over how her team, the Wonderbolts, are useless when they actually try to help out and be heroes (a deconstruction of their poor track record in the FiM series itself). This is then reconstructed when Dash refuses to accept Spitfire's claims of being a Broken Pedestal, pointing out how they still inspire others to be heroes.
Sort of semi-subverted for Fantöm in the Noob franchise, as he turns out to have been Locked Out of the Loop, but still gets a hard time from some of the characters for not noticing that things were much easier for him than they should be on his own.
In the DuckTales episode "Where No Duck Has Gone Before", Huey, Dewey, Louie, and Doofus idol worship Major Courage, hero of the TV show "Courage of the Cosmos." The boys go on the show and are blind to the fact that their hero is just a vain, egotistical actor, and pay no attention to Launchpad and Scrooge's statements to the effect that his derring-do isn't real. When they realize that they have really been launched into outer space and real aliens have captured them, Courage panics, and the boys see what a coward he really is ("real heroes just do their jobs!").
Courage: What happened? What's going on?
Huey: We're going home!
Dewey: No thanks to you!
Doofus: You've been saved by a real hero — Launchpad McQuack!
Bravestarr did this in the simply-titled episode "Fallen Idol". A bit unusually, while Bravestarr is shocked to hear that his mentor Jingles Morgan is wanted for murder, he doesn't seem to doubt the truth of it at any point. (Then again, the evidence against Jingles is pretty overwhelming. The victim was his opponent in a martial arts tournament, who he killed in an arena in front of hundreds of witnesses.) Upon his arrest, Bravestarr attempts to understand why, only for Morgan to pause and show how far he is down the Moral Event Horizon by saying "I never asked to be your 'hero'".
One Saturday morning cartoon special about the 10 Commandments. In the "Thou shalt not worship false idols" segment, the dumber of the kids finds himself among crumbling statues of sports and rock-and-roll idols, although exactly why these kinds of idols aren't good (other than "not being God") isn't explored or has been lost to memory.
Batman: The Animated Series does this to some extent in the episode, "Beware the Gray Ghost". The eponymous character (voiced by Adam West) was the hero of an in-universe TV show that Bruce Wayne loved as a child, and an inspiration to the latter's own vigilantism. The actor, although not mean, is a bitter old man who has suffered from longterm unemployment, and briefly grows to hate his old role. Batman is quite disappointed when this Reality Ensues, but once it turns out that rediscovering the past is vital to solving a crime, the actor fortunately rediscovers his passion, aids Batman on his quest, and the episode ends on a very high note.
Also, "Baby Doll" is a rare example where a character feels this about herself. The villain, Mary Dahl, is a deformed actress who could never get any roles except as the baby in a sitcom. She goes mad and kidnaps the cast of the show, attempting to recreate the one situation in which she was happy. Eventually, when Batman tries to stop her, she initially resists, but eventually breaks down after realizing what she's become.
Men In Black: The Animated Series: Kay's mentor Alpha betrays him and the MIB after merging with some alien technology that allows him to combine with anything.
On The Venture Bros., Brock Samson's mentor Colonel Hunter Gathers is thought to have gone rogue and Brock is sent on a mission to hunt him down and kill him. Brock is disgusted to find that his mentor, who insisted on never killing women or children, apparently killed the woman he'd slept with the night before (she turns out not to be dead, but Brock doesn't know that). In the end, we see that his mentor ran off to get a perfectly innocent sex change, and the morals he passed down to Brock invalidated the now-female mentor as a target. Though as it turns out in season 4, he really did go rogue...but he wanted to do things his own way rather than following OSI's strict policies. And with the Season 4 finale, it appears that Colonel Gathers is the new commander of OSI, letting him come full circle.
Season 3 showed flashbacks where Dr. Jonas Venture Sr. was either a complete Jerk Ass or just too naive to realize the damage he was inflicting on his son due to his womanizing and seeming disregard for human life.
The eponymous character tracked down his favorite author only to find that she'd become mean and surly because of years of writer's block. His insistence that she was still his favorite author, despite how terribly she treated him before and during the interview for his school report, is the catalyst for her future change of heart and eventual return to writing.
Eugene turned bad when he found out the actor from his favorite TV show wasn't anything like the character he plays. The same episode also subverts it when the actor saves Eugene and Arnold from falling to their deaths, at great personal risk. As a result, it becomes a case of Warts and All, since Eugene realizes that for all his flaws, the actor is still a fundamentally good person.
Then there was the time Phoebe found out her favorite singer, Ronnie Matthews, was a lip-synching hack.
The Simpsons has an episode where Lisa learns that Springfield's founder Jebediah Springfield, contrary to his rugged frontier hero image, was actually a bloodthirsty pirate who once attempted to kill George Washington. Though initially dedicated to revealing the truth to the town, she changes her mind since she didn't want to take away the inspiring (fake) image people had of Springfield.
Family Guy does this with Stewie's love of fictional kids show Jolly Farm. He goes to London only to find out Jolly Farm isn't real, Pengrove Pig is a pervert in a suit and Mother Maggie hates children and speaks with a Cockney accent.
Daria has Tommy Sherman in the episode "The Misery Chick," who disappoints and disgusts everyone who meets him, even Kevin Thompson who idolizes him. As soon as he's killed in an accident, Kevin forgets all about his problems with Tommy's character.
In Book 2 of Avatar: The Last Airbender, Zuko is suddenly exposed to the horrors of what his beloved Fire Nation is actually doing to the world. He shoves it aside for a while, though, and helps Azula defeat Aang so he can return to the Fire Nation, where he's welcomed back by their father, Fire Lord Ozai and almost goes completely back to his old self, until Azula and Ozai plot to incinerate the entire Earth Kingdom, and he can no longer deny he's on the wrong side of the war.
The Legend of Korra: The Equalists, specifically the Lieutenant, to Amon. Amon preached equality and removed the Bending of people to achieve it. Amon was revealed to be a Waterbender, and that shook the support from his cause. When the lieutenant finds out, he smashes his equalist mask, and attacks Amon, calling him a traitor, and screaming that they all had trusted him.
In the Book 2 premiere, Korra hasn't had a good opinion of her father Tonraq since she learned he was one of the people behind the compound (Tenzin had a hand in that too) along with his exile from the Northern Water Tribe, and the fact he is treating her like a child. But later on, Korra swears off loyalty to Unalaq once it's revealed he not only fixed her father's trial to send Tonraq to prison and also to appear "merciful", but also caused Tonraq to be banished so that he could become chief of the Northern Water Tribe. After that, she reconciles with him and Tenzin.
Star Wars: The Clone Wars: When Ahsoka was framed for multiple murders, terrorism and sedition, the Jedi Council abandoned her and made no effort to conduct their own investigation, and the Senate Court were more than happy to sentence her to death. Anakin and Padmé were the only ones to support her in all what she went through, and even after it's discovered that she was innocent, and she was offered back to the Jedi Council with a promotion, the damage was already done. Her faith in the Council was shattered and she leaves them completely.
Batgirl: Yeah, you're Mother of the Stinkin' Year!
Sofia the First: Princess Amber used to have a crush on Prince Hugo until she saw him cheating during a failed attempt to keep Sofia from entering Royal Prep's Derby Racing Team.
Transformers Prime has this between Megatron and Orion Pax in the beginning of season 2. Millennia ago, they were both heroic until Orion Pax's becoming Optimus Prime caused Megatronus' jealousy to lead him to becoming the villainous Megatron. When Optimus loses his memory, Megatron quickly resumes the master-pupil relationship for as long as he can until Orion starts figuring out that Megatronus isn't quite as noble as he remembers.
In Codename: Kids Next Door, Cree was formerly Numbuh Five's mentor, her Cool Big Sis (literally and figuratively) and one of the best operatives of all time. As you might expect, then, the fact that she turned traitor made her one of the worst examples of this Trope, becoming the Cain to Numbuh Five's Abel in the process. (To make it worse, if Operation: M.A.U.R.I.C.E.) is any indication, Cree seems more than willing to reconcile with her sister, but only on her terms; she seemed overjoyed when Abby briefly seemed to be willing to join her. Fortunately, Abby's other idol convinced her otherwise.)
In Rocket Power, Otto learns that his favorite skateboarding action hero movie star is coming to town to film another one of his movies.
