Ben Kenobi: Obi-Wan Kenobi? Obi-Wan... Now that's a name I've not heard in a long time. A long time.
Luke: I think my uncle knows him. He said he was dead.
Ben Kenobi: Oh, he's not dead. Not yet.
Luke: You know him?
Ben Kenobi: Well of course I know him. He's me. I haven't gone by the name "Obi-Wan" since, oh, before you were born.
A character, usually the protagonist, is looking for someone, often an older, wiser character. During the search, he meets a stranger, and the conversation turns to the sought-after character. The stranger will typically either respond, "Oh, I know him well..." or else act as if he's never heard of the person. Either way, in time it is revealed that this stranger is the sought-after character.
Often, the stranger is playing dumb about their true identity in order to assess the searcher's character and intentions, the idea being that the searcher's behavior will be more genuine in the presence of someone they perceive to be just an ordinary stranger. This can lead to a painful lesson for the searcher once he learns the truth about the stranger, making this a favorite form of introduction among Trickster Mentors.
It still satisfies this trope if the person tells the searcher straight-out, without pussyfooting around or playing games, who he is, as in the opening Star Wars quote.
Further confusion can arise if the sought-after character is of a different gender, race, species, etc. than the searcher was expecting, such as when a sought-after "doctor" turns out to be a woman scientist. Or maybe the searcher was just Expecting Someone Taller.
Can also be Luke, I Am Your Father if the sought-after character is the searcher's parent. See also You Have No Idea Who You're Dealing With, Right in Front of Me, King Incognito, Actually, That's My Assistant, I Am One of Those, Too, ...But He Sounds Handsome, Mistaken for Servant, and ...And That Little Girl Was Me. Might invoke Your Costume Needs Work if a character thinks the person is just someone dressed up to look like them. For when you weren't expecting something to be a character at all, see I Am the Noun. Compare and contrast Something Only They Would Say and No Doubt the Years Have Changed Me, where the unrecognized character is someone the oblivious party had actually known before.
Not to be confused with Confronting Your Imposter, which is sort of an inverse of this trope. Also contrast Friend of Masked Self, where the misidentified character doesn't admit "I am him" because it would ruin his Secret Identity.
Given that this trope is about a plot twist, here be spoilers.
- A commercial for MagnaFlow exhausts has a police officer pull over a car for speeding, and while asking for the driver's license, asks who he thinks he is, Mario Andrettinote ? Mario promptly introduces himself and claims the car wasn't speeding. In a twist though, Mario is actually the passenger; the driver was his grandson Marco, himself an Indy Car driver.
- Happens at the end of the first Baccano! Light Novel, when a Japanese tourist in the frame story decides to ask the narrator (whom is assumed to be Maiza) where Firo is now, seeing as he's not present like everyone else is. "Maiza" responds...?
Isn't he right here?...Oh, That's right, I have yet to introduce myself. Well, normally with business associations, I just leave without having ever said my name...
- In a particularly funny example, in Black Cat, Train eventually acquires an impostor, who the gang meets. Sven and Eve want to smack him upside the head, but Train listens to his wild stories with a look of wonder on his face, and eventually agrees to become the impostor's apprentice. When people challenge the impostor, Train steps up to the plate, claiming that the other guys aren't "worthy for [Train's] master to spit on." THEN the imposter notices the XIII tattoo, and the unique gun...
- This is played with in Cowboy Bebop. When Spike and Jet go in search of the hacker known as Radical Edward, they get so many widely-varying stories about who Edward is and what he's supposedly like that Jet sarcastically comments that they're looking for a 3-year-old, 7-foot alien genius that plays basketball. When Ed hacks into their computer and they ask who Radical Edward is, she responds in her perpetual adorable third person way of talking, "But Ed is Ed." In case it wasn't clear: Edward is very much a girl tacking on the "Assumed Wrong Gender" part of this trope.
- Hilariously inverted in Dragon Ball Z, where, upon meeting a normal monkey, Goku instantly assumed him to be the legendary King Kai, and spent a while fooling around with him before the real Kai - who himself could easily qualify for this trope under different circumstances, what with how he looks and acts - shows up.
- A thorn in Edward's side in Fullmetal Alchemist, that people are more willing to believe that Alphonse is the famous "Fullmetal Alchemist" and not him. (Al is a walking suit of armor...)
- Played with in Howl's Moving Castle. It's not clear when Sophie realizes the strange young wizard is Howl himself.
- IGPX Immortal Grand Prix:
- Team Satomi's coach, Andre, turns out to be The Rocket.
- Also, Team White Snow's captain isn't Zanak, it's Max, although it's easy to make the mistake since he's the Forward and all the other team captains are Forwards.
- Kemono Friends: For much of the series, Racoon is chasing after a hat thief, and along the way she runs into a number of Friends who tell her about their encounters with an incredibly helpful person named Kaban. When she finally catches her prey in Episode 11, her friend Fennec, who's been paying more attention to those stories, calmly explains that the "Hat Thief" is Kaban. Racoon initially doesn't believe her, saying that someone as good as Kaban would never steal, but eventually she realizes that she had it wrong from the start and apologizes.
- In the manga adaptation of The Legend of Zelda: Ocarina of Time, Link meets young Zelda, who has escaped from the castle and disguised herself as a commoner girl. When Link asks her about Princess Zelda's whereabouts, she tells him that she and Zelda are good friends and that she'd introduce him if he played with her for a whole day.
- In Love, Chunibyo & Other Delusions, Shinka tries to convince Sanae that she's "Mori Summer," if only to be able to confiscate the latter's copies of her own Mabinogion. Fails miserably, because Sanae expected the philosopher from Mabinogion, not the jaded high-schooler desperate to purge her past delusions.
- Inverted in Monsters of Wanted! (1998). Ryuuma expresses the desire to meet and duel the "swordsman king" who is said to be the greatest swordsman in the world. After he saves the town from a dragon and leaves, one of the residents remembers that Ryuuma himself has been called the swordsman king by the various people he has saved.
- Guaranteed to happen three-quarters of the time in the Pokémon anime. This also applies to the games, to a lesser extent. To give one example, on Cinnabar Island, Ash and company run into an old hippie who tells them riddles to give them clues to find the Gym that is run by Blaine. When the figure out the last one and find the Gym, the old hippie is there - he is Blaine.
- Subverted with Max, who was only pretending to be the gym leader in Petalburg City. He initially managed to fool Ash...only for his sister and father (the latter being the real leader) to show up.
- Also happens in Pokémon Adventures; when Red wanted to battle the Cerulean City Gym Leader, Misty took him to the Gym and revealed that she's its Leader.
- And again in Pokémon Origins, when Red is upset about his Pokemon not being strong enough, a man shows up and suggests that Red take on the Gym Leader challenge to make himself stronger, starting with the gym in Pewter City run by Brock. When Red arrives at the gym, guess who Brock turns out to be? Of course, the viewer can tell that it's Brock the moment he appears.
- For the first few episodes/chapters of Trigun, the story follows Meryl and Millie investigating every lead they can find on the location of the most wanted criminal on the planet, Vash the Stampede. And, by chance, everywhere they go, they run into the same hapless, clueless, spiky-haired dork blundering into trouble...
- Made even funnier because Millie would do some variation of "hey there he is" in noticing their new friend every time Meryl would say to be on the lookout because there was a sighting in that town. Though, she does start to wonder about the fact both their target and new friend have the same name; but Meryl doesn't believe a goofball like him could be a deadly criminal.
- Early in Rave Master Haru finds himself so desperate for leads as to where to find the legendary blacksmith Musica that he's willing to be at the beck and call of a drunkard who may or may not know where the person was. Said drunk turned out to be...
- Happens over and over consecutively in almost every town the Sanzo party enters in Saiyuki. Quite often word reaches villages that the great Sanzo-party has happened through the area in which many humans search after them for blessings while many youkai look to eliminate them. What they don't expect is for the Great Holy Priest Genjo Sanzo to be a young jerkass blond guy with a gun and a smoking problem, and his devoted acolytes a group of youkai.
- In fact, it has happened so often that when for the first time it doesn't happen to them but instead, another group of wandering demon-slayers, they're actually taken by surprise.
- In The Vision of Escaflowne The Movie, Van and Hitomi are looking for a man named Dryden Fassa - then they meet someone who pretends not to know who Dryden Fassa is, before turning out to be actually him.
- In Dungeon Twilight, vol. 1: Dragon Cemetery, when Marvin the Red meets his idol Marvin the Dragon, the latter first pretends to be someone else.
- For years, Tony Stark had to put up with the story of Iron Man being his personal bodyguard. Thus, a recurring bit was how folks would bad-mouth Iron Man as "just an employee" right to his face. In his final The Avengers issue, Kurt Busiek finally paid off on this as a Stark employee berates Iron Man for using Stark enterprises for an adventure, howling that he had no right as just an employee. Her colleague takes her aside to whisper to her the news that just broke that Iron Man is Tony Stark and she's chagrined realizing she just chewed out her boss.
- The Adventures of Doctor Bell: When a rabbi and a priest show up asking for Joseph Bell, he answers with "I've had to stand him every day of my life."
- When Bruce Banner goes looking for the Panchen Lama in Ultimate Wolverine vs. Hulk, he is greeted at the monastery doors by a wizened old man who assures him that the Lama is inside and offers him hot cocoa. Banner shows a flash of insight by assuming the old man is the Panchen Lama, calling it "one of those Yoda things"... but nope. He's talking to Steve, who makes hot cocoa.
- The "Pagliacci" joke that Rorschach heard from the Comedian in Watchmen.
Rorschach: Man goes to doctor. Says he's depressed. Says life seems harsh and cruel. Says he feels all alone in a threatening world where what lies ahead is vague and uncertain. Doctor says, "Treatment is simple. Great clown Pagliacci is in town tonight. Go and see him. That should pick you up." Man bursts into tears. Says, "But doctor... I am Pagliacci".
- The Evabon Saga: When Gard and Tygra initially met the latter believed the former to be some long tormented victim of the former himself whom the latter perceived to be a monster. Upon realizing that Gard was not a monster and that by wanting to kill him he would have committed murder, Tygra breaks down into tears.

- In American Wedding, the main characters are looking for a particular dress designer to make a dress for the bride, and accidentally wind up in a gay bar. Their comical antics impress a group of gay men, one of whom finally reveals that he is the designer they're looking for.
- In Batman (1989), Vicki Vale corners a man at a swish party at Wayne Manor and asks whether he's seen elusive billionaire Bruce Wayne. He says he hasn't. Later, as she and Alex Knox are in one of Wayne's rooms, making fun of the statues, the man appears behind them and informs them that the elaborate antique armor they're currently laughing at is Japanese. How does he know? "Because I bought it in Japan. Bruce Wayne."
- Batman Begins. In order to get the needed training for his war on crime, Bruce seeks out Ra's Al Ghul, the head of the Asian League of Shadows. He ends up dealing mainly with Henri DuCard, the League's second-in-command. Ra's tends to sit in the background and be imposing while DuCard does all the work of testing and advising Bruce. When drama ensues and everything starts exploding, Bruce saves DuCard; he doesn't discover until much later that DuCard was really Ra's Al Ghul all along, using another man as a decoy.
- In Braveheart, as William Wallace arrives at Stirling before battle. This doubles as a Historical In-Joke, as the real William Wallace was a giant of a man, at least a foot taller than actor Mel Gibson.
Wallace: Sons of Scotland, I am William Wallace!
Scottish Soldier: William Wallace is seven feet tall!
Wallace: Yes, I've heard. Kills men by the hundreds, and if he were here, he'd consume the English with fireballs from his eyes and bolts of lightning from his arse!
[the Scottish Army laughs]
Wallace: I AM William Wallace!
- Twisted on itself in Circle of Iron, where the hero Cord is seeking the Book of Enlightenment held by the mysterious Zetan. Along the way, he adventures with the Blind Man, a wise man and incredible martial artist who serves as a sort of informal master. David Carradine plays the Blind Man, and also the characters for several trials Cord must face. In the end, Cord thinks the Blind Man is actually Zetan, but he isn't—he's just seen the Book of Enlightenment.
- In the movie version of Clue, in one of the possible endings, Wadsworth reveals himself as Mr. Boddy, saying that the alleged Mr. Boddy was, in fact, his butler, and not the other way around.

- In El Diablo, Anthony Edwards' character is searching for legendary "Kid Durango" with the help of a man named Van Leek only to later discover that the exploits of Kid Durango are based on the adventures of Van Leek.
- Subverted in Die Hard when the hero and the Big Bad meet. It looks like Gruber tricks McClane, but in fact McClane sees through it and gives his adversary an unloaded weapon.
- In The Distinguished Gentleman, when Eddie Murphy's love-interest-to-be enters a reception for the new Congressman Johnson (Murphy), she goes right up to him first and asks where Congressman Johnson is, then goes on to bad-mouth him a bit before he reveals his Congressman's pin (hidden behind a clipboard he's holding).
- In Dragonheart, Bowen swears vengeance on a Dragon who kept prince Einon alive with an ancient ritual and turned him evil (not realizing Einon was evil to begin with). When he meets Draco many years later and is told he is the Last of His Kind, Bowen's first thought is that the dragon he hunted must already be dead, and does not figure out that Draco is that dragon until they travel to Avalon together.
- Used in Jackie Chan's Drunken Master, where the main character Wong Fei-Hung flees from home in fear of being sent to train with the infamous Beggar So, master of the style of the eight drunk gods. He meets an old geezer who displays some highly unusual but equally effective moves, and they share a leg of the journey—no bonus point for guessing who this turns out to be.
- Sort of done in Face/Off: "I am Castor Troy!"
- In Fast & Furious, Dominic and Brian are searching for Campos, the leader of a narcotics gang. Only near the end do they realize Campos is actually the man who pretended to be his assistant.
- Dragged out to a painful degree in The Giant Spider Invasion, where the leading man meets the female scientist and persists in believing he must really be meeting with some male relative of hers for some time before she explains that, no really, she's the "doctor" he has an appointment with.
- A somewhat stranger version happens in the Muppet adaptation, Hey Cinderella!. Through various circumstances, neither Cinderella nor Prince Arthur realize they danced with one another at the ball, even though they already met. (Cinderella was looking for a gardener named Arthur and Prince Arthur was looking for a peasant girl named Cinderella). When Arthur goes searching the kingdom for the beautiful maiden he danced with, on his father's orders, he and Cinderella finally meet again and their actual identities are revealed to one another. Cinderella is pleased to learn that the prince she danced with and Arthur the gardener are one and the same, but it takes a little more evidence to prove that she really was the beautiful maiden.
- Indiana Jones and the Last Crusade: Indy and Marcus are instructed to meet Dr. Schneider in Venice to begin their search for the Holy Grail and Indy's missing father.

- In Kill Bill: Volume 1, The Bride pretends to be an American tourist upon first meeting Hattori Hanzo in his Sushi restaurant. Hanzo himself is an attempt to play the trope: He's a legendary sword maker posing as a sushi chef. Only the Bride knows who he is, so he can't play that trope on her.
- In The Last Starfighter, when Centauri asks who made the highest score on the Starfighter video game, Alex replies: "Alex Rogan. You're looking at him."

- Done with Holly Goodhead, the Moonraker Bond Girl.
- In Obsessed, when the main character and the psychotic temp first meet, the latter mentions having to deliver a file to "Derek Charles' office", not knowing that she is talking to him.

- Star Wars:
Padmé: You assume too much.
- The Phantom Menace: Queen Amidala traveled with a host of decoys for security purposes, it seems. What makes her an example of the trope is that she's always disguised as one of her own attendants, as opposed to moving completely behind the scenes. Qui-Gon knows handmaiden Padmé is the queen, and takes every opportunity to rile her up when mentioning how the queen will approve of his choices.
"Of course I know him; he's me."
- In A New Hope when Luke's looking for Obi-Wan Kenobi, although in that case he's actually already an acquaintance under another name ("Old Ben" Kenobi). Luke momentarily speculates that it might be Old Ben, but he's not expecting it. He also wonders if Obi-Wan might be related to Ben, and even asks him if that's the case. In this case, Ben tells him straight-out that he's Obi-Wan instead of hiding it.
- The Empire Strikes Back follows this formula perfectly when Luke is looking for Yoda. In addition, Darth Vader turns out to be Luke's long-lost father.
- Castor/Zuse in TRON: Legacy.
- In The Usual Suspects, it turns out that Verbal Kint is Keyser Sose.
- In the 1953 film version of The War of the Worlds, Sylvia gushes on and on about the scientist who was expected to visit the first landing site. When the man she is talking to says he knows the scientist, she asks him what he's like. He just mumbles a few words and gestures toward himself.
- In one scene of Young Guns, a bounty hunter is bragging to a woman about how he is going to kill Billy the Kid. It just so happens that Billy the Kid is in the same saloon, and questions the bounty hunter about how he's going to kill the outlaw when he finds him. Not knowing who he is talking to, the bounty hunter gives Billy his gun when asked to see it, and Billy removes all of the bullets before returning it. Billy then asks the bounty hunter for a description of himself, and upon looking in a mirror, exclaims that he has found himself. Amazingly, despite Billy admitting who he was to the bounty hunter's face, said bounty hunter refuses to believe that Billy the Kid, is Billy the Kid, until he is shot.
- Super Mario Bros.: The lawyer assigned to the Mario Bros. warns them that they don't want to deal with Koopa, who he describes as "one evil, egg-sucking son of a snake." It's ultimately revealed that their "lawyer" is Koopa.
Luigi: You're Koopa?! But you said you were-

Justice: Oh...(sheepishly) You know, you sound a lot taller on radio.
- In "A Witch to Live" from the 1632-universe short story collection Ring of Fire, when Father Friedrich Spee is sent to defend a young woman from a false accusation of witchcraft, he finds her case being retried by the Trapped in the Past modern Americans — and himself sitting in the rectory when Father Mazzare, the American priest, gets out an encyclopedia to look up the name of the great heroic opponent of witchcraft in the 1630s ... Father Friedrich von Spee.
- Robert A. Heinlein's short story —All You Zombies— in which, thanks to a great big Timey-Wimey Ball, every character, male or female, was actually the same person.
- In The Anubis Gates, Doyle/Ashbless tells his buddy Jacky about Elizabeth Tichy, the young woman he'll be marrying the next month (from Doyle's familiarity with Ashbless' biography), and is surprised by how annoyed Jacky is by his confidence on the subject. Turns out that Miss Tichy's middle name is Jacqueline...
- At the end of A Brother's Price, when Jerin returns to his fianceés after getting kidnapped, he tearfully confesses that he may have slept (he doesn't remember the night clearly) with his rescuer, Cira, and is now Defiled Forever, so he can't marry them. Whereupon his bride Halley, whom he has not met yet, turns around to show her face: She is Cira, and remembers well that he resisted her attempts to seduce him.
- In George Bernard Shaw's Caesar and Cleopatra, 16-year-old Cleopatra is hiding from the invading Romans, and she runs into a nice old man who turns out to be Caesar. Hilariously, she tells him she's heard Caesar has a nose as big as an elephant's; he self-consciously fingers his nose in response. Then, when he decides to break part of the truth to her: "Do you notice that I have a rather long nose? It is a Roman nose, Cleopatra."
- Ciaphas Cain: On his first deployment with the Valhallan 597th, Cain finds himself chatting with a very attractive Glamorous Wartime Singer by the name of Amberley Vail. Seeking to impress her, he goes on at length about the Inquisitor who's already on the planet, who is obviously the rogue trader Orelius (a very popular disguise to the point of Flanderization), to which she responds with appropriate gasping and widening eyes. Later on, he gets called in to rescue the Inquisitor from a firefight, at which point he is introduced to... Amberley Vail, Ordo Xenos Inquisitor.
- Less embarrassing given that Orelius is a close associate of Amberly and was at that moment doing exactly the job she'd have to if he hadn't been in the area. Cain's reasoning justifying the presence and activity of an agent of the Inquisition was good enough, and his talk about rogue traders funny enough, to genuinely impress her - a fact which greatly influenced the remainder of Cain's career.
- In one book, Conan the Barbarian is invited to meet the leader of a group of rebels plotting to overthrow their king. Perhaps as a safety precaution, the person he is led to and the person leading him are impersonating each other.
- A variant in Feet of Clay when a man claims to be a good friend of the Commander of the Watch to intimidate the watchman he's talking to, who is in fact Commander Vimes. As a bonus in an earlier letter to Vimes the same man claimed to be a good friend of the Patrician, an unlikely claim to anyone who knows the Patrician. As Vimes does.
- In Monstrous Regiment, Vimes assures the protagonists that he'll take them to the leader of the Ankh-Morpork regiment.
- And in Snuff, when Vimes boards a riverboat claiming to be the police, an incredulous man asks "Who do you think you are? Bloody Commander Vimes?" The commander replies by asking the man if he's always this lucky.
- Thief of Time: A young braggart monk confronts the little bald wrinkly smiling "cleaner" Lu Tze. His teacher uses the moment to hammer home Rule 1 — "Do not act incautiously when confronting little bald wrinkly smiling men". It's implied that the rule was written with Lu Tze in mind.
- In The Divine Comedy, a pagan poet just released from Purgatory introduces himself by explaining how the wisdom of Virgil (especially in The Aeneid) allowed him to appreciate the newly-emerged Christianity and convert in secret. The Protagonist can't stop himself from smiling at this to the poet's confusion; this confusion allows Dante to reveal that his guide through the afterlife is "that same Virgil from whom [he] derived the power to sing of men and of the gods."
- An almost identical incident occurs in Louis L'Amour's Fair Blows the Wind, when a tall, weather-beaten Scot tells Tatton Chantry that he can lead him to the legendary sword master Fergus MacAskill, with whom Chantry wants to study fencing. The Scot is Fergus MacAskill himself.
- Averted in the book Fangirl. Cather while in college meets a fan of her fanfic Carry On, Simon, who gushes about how well the author writes. Cather decides not to break the news to her but quietly relishes the praise.
- In Assassin's Apprentice, the first book of the Farseer trilogy by Robin Hobb, Fitz asks a woman where he can find Hod, who is going to teach him swordfighting. Naturally, the woman is Hod.
- Used in the Geronimo Stilton book My Name is Stilton, Geronimo Stilton, when Stilton prepares to meet his new personal assistant, Pinky Pick, whom he hired without even an interview, based on her impressive resume. When he finds a 14-year-old girl in the lobby who announces "My name is Pick!" he assumes that she's the daughter of his new assistant, until she clarifies that she is indeed his new assistant.
- In The Great Gatsby, the title character throws lavish parties at his mansion, but does not mingle with his guests. Consequently, hardly anyone even knows what he looks like.

- Harry Potter

- In Harry Potter and the Prisoner of Azkaban, Remus Lupin says of Moony, Wormtail, Padfoot, and Prongs, "We've met." He's Moony.
- Judge Dee frequently disguises himself as a peasant or traveling martial arts instructor (the latter suits him much better) during his investigations. This frequently results in him dropping "I am the magistrate" when things get serious and someone suggests to report to the judge.
- In the Chinese Light Novel The King's Avatar the protagonist Ye Xiu reveals that he is in fact a famous pro gamer to his new boss Chen Guo, she doesn't believe him at all.

He plays along for a little while before revealing his identity.
- This occasionally happens to Halt in Ranger's Apprentice. Given that he's an in-universe Memetic Badass, people expect a seven-foot-tall man who wrestles bears, shoots fireballs from his eyes, and lightning bolts out his arse. They're disappointed, and sometimes flat-out disbelieving, when it turns out that Halt is a short Deadpan Snarker who cuts his hair with his own knife.
- In The Reader (2016), it's revealed near the end that Rajar, the assistant of Tanin, is the one who has been commanding the Impressors to kidnap young boys and leading the raids on the Ephygian bay in the name of Serakeen. Serakeen isn't a real person, but for all intents and purposes Rajar fulfills the role required of the character.
- Shannara: In the Heritage of Shannara series, Morgan Leah spends a long time arguing with a boy mopping floors that he wants to meet with Matty Roh, a resistance contact and owner of the inn they are talking in. After being thrown out twice by the small, skinny boy, he comes in holding the resistance leader's badge, pushes it in the boy's face and demands to speak to Matty. Turns out the reason a small skinny boy can beat a burly highlander is that she's not a boy and she knows Waif-Fu.
- The last Sherlock Holmes novel, "The Valley of Fear", culminates in the infiltration of a criminal gang by a man from Pinkerton's. A trap is set for the private investigator, where it is revealed that McMurdo is Birdy Edwards.
- In one of the Star Trek: Stargazer novels, Admiral McAteer is strolling the Starfleet Academy grounds, and starts thinking about Boothby, whom he admires. At least, he's heard good things about the man. He encounters an elderly groundskeeper whose general attitude annoys him (and who has the gall to tell him off). Eventually, he demands the groundskeeper's name. Upon being told he's talking to Boothby, McAteer walks off spluttering.
- Star Wars Legends: Isard's Revenge varies this when Wedge Antilles disguises himself as an Imperial with a prosthetic hand and half a face, and has to make conversation with an actual Imperial, who has a conspiracy theory that the members of Rogue Squadron are actually quite easy to kill, but the reason why members like Wedge Antilles seem to have stuck around for so long is because they get cloned. Later in the book Wedge takes off his disguise in front of this Imperial.
Wedge: You recall mentioning that you'd killed plenty of Rogue Squadron members at Brentaal, and that Wedge Antilles would be back?
Wedge: You were right. I'm Wedge Antilles. I'm back. (shoots him)
- Turned around early in the Sword of Truth novel Wizard's First Rule. Kahlan seeks out a Last of His Kind wizard, and Richard leads her to his old friend Zedd, who he's confident can help them. Richard later figures out the wizard is his friend, Zeddicus Zul Zorander.
- Played at least twice more in later books. First, in book two, Richard goes into the Prelate's office in order to speak to her. He first mistakes her for a maid (powerful magic users don't tend to dress too elaborately in the series). In book four, an old childhood friend is told by a witch to seek out Lord Rahl, who can help her find Richard. Of course, she meets Richard himself, and has trouble believing he is Lord Rahl.
- A recurring theme in Water Margin. Every outlaw, criminal, and bandit in China admires Song Jiang but very few know what he actually looks like. Many times do these bandits and outlaws serendipitously discover that they have just met Song Jiang just as they are about to rob, murder, or inflict some other mayhem on him.
- Occurs in A Spell for Chameleon, the first of Piers Anthony's Xanth novels, the first time Bink encounters Magician Humphrey.
- In The Young Ancients the protagonist Torrence is known to all his friends as Tor. This is also the name that gets spread around when he becomes a wizard famed across an entire continent, leading to some confusion in formal settings where he uses his full name. Several other people just flat out refuse to believe the skinny kid in front of them is the same wizard they've all heard of.
- Deliberately invoked in the Dragonlance trilogy The War of Souls. Morham Targonne, the Lord of the Night, is a mild, unassuming middle-aged man despite being the head of an order of Black Knights feared across the continent; when giving an audience to people he hasn't met before, he'll typically invite them into his office and keep working quietly at his desk without acknowledging them, leaving the visitor to assume that this man is the Lord of the Night's secretary. He'll watch their reactions for a while, magically read their mind a bit to steal secrets, and once he's satisfied himself only then announce to said visitor that they are, in fact, in the presence of the Lord of the Night. Cue Oh, Crap!.

- Played With in the HBO Comedy Special Rodney Dangerfield: Nothin' Goes Right. The cold open has Rodney having his makeup done by an attractive woman, and a male barber giving him a shave. Putting the moves on her, Rodney says, "Why don't you tell your husband you're working late, and then you and me'll go out for a drink?" She replies, "You can tell him that yourself.

When he meets with the class in the Roosevelt Room, he gives them a fake, fanciful history because he doesn't know anything about the White House. The class's teacher takes him outside the room and berates him. He responds by telling her his and the administration's travails (including that he "accidentally slept with a prostitute"), and asks her to tell him which of the students is Leo's daughter so he can see that she gets personal attention. The teacher reveals that she herself is Mallory, Leo McGarry's daughter, to which Sam responds, "Well, this is bad on so many levels."

At the premiere, Jimmy uses the restroom at the same time as Kevin Smith (as himself). Jimmy does not know Kevin Smith.

- This is a very old trope: Jesus does it in The Gospels no fewer than three times after his resurrection, showing himself to the disciples — but somehow they don't realize it's him. (John 20:14, 21:4; Luke 24:16). The conversation with the Samaritan woman in Sychar (John 4:1-26) comes close to it as well, with Jesus revealing at the end of the conversation that He is the Messiah for whom she's waiting.
- In Homer's The Odyssey, Odysseus is helped by the gods to disguise himself as a an old tramp. He then enters his own household to investigate how suitors of his wife (believing him dead) are abusing his estate's hospitality. He initially introduces himself to his own son, Telemachus, to observe his reactions and intent to the developing situation. Once satisfied that his uninvited guests are pillaging his stores and furthermore treating him with disrespect, much to his son's chagrin, he reveals his true identity and proceeds with the help of Telemachus to slaughter the lot of them. This is undoubtedly the oldest example of the trope known. Later in the novel he reveals himself to the swineherd and cowherd after determining that they were still loyal to him, shortly before springing his trap on the suitors.
- Robin Hood: Some versions have this with King Richard.
- This also happens to Saul in I Samuel when meeting Samuel for the first time. Saul is looking for a prophet of God and goes to a town where one is reputably staying.

Spaulding: You're Emanuel Ravelli?
Ravelli: I am Emanuel Ravelli.
Spaulding: Well, no wonder you look like him. But I still insist there's a resemblance.
- In Camelot, a nervous King Arthur and Queen-to-be Guinevere run into each other before the wedding. Guinevere, not knowing it's Arthur, complains a bit about having to marry a total stranger and is assured that the king isn't really all that bad.
- In the Richard Strauss opera Elektra, Elektra treats her brother Orestes as a stranger until he asks why his sister doesn't recognize him.
- She Stoops To Conquer takes place almost entirely within the space between the deceit and the revelation. Charles Marlow, on the way to a blind date, stops at what he thinks is an inn and flirts with the barmaid. He's actually at the manor he was traveling to, and the barmaid is his date.
- Played very simply in Assassin's Creed: Brotherhood, where Ezio helps a woman carry a box and talks to her about Ezio, eventually revealing that he is Ezio.

If Jensen has a CASIE aug, however, he can use it during the conversation to immediately see through Tong's act and call him out on it, winning the social battle.
- In Dragon Age: Origins, Oghren runs into you by this way if you didn't talk to him first in the tavern. When you're ready to set out to Deep Roads to mount a search party for a paragon who is needed to support a king candidate (and who happens to be Oghren's wife), he stumbles into you, asking if you have seen a Grey Warden. You can play dumb and ask what does (s)he look like, and he'll say a long list of Mary Sue Knight in Shining Armor qualities with appropriate Purple Prose, and is instantly disappointed to see that you're the person he is looking for.
Oghren: Seems that the requirements have gone way low.
- In Final Fantasy V, the sage Ghido turned out to be the turtle that Bartz was bugging at the moment.
- In Final Fantasy Tactics Advance the first time Marche meets Ezel Berbier, Ezel speaks about himself in third person and it isn't revealed until later that he was in fact Ezel Berbier.

- In Final Fantasy Tactics A2, the mage in the mountains (Lezaford) pulls this on Luso.
- In Fire Emblem: Path of Radiance, Ike is put to the task of finding the apostle, empress of the nation he was seeking assistance from, on his ship. He finds a small girl, and tells her to wait since he needs to find the apostle. Naturally, this girl turns out to be the apostle.
- In a bit of a variation, back in Fire Emblem, Dart tells Karel about dozens of legendary warriors, like a giant who shrugged off all blows and a mage who could freeze his enemies' blood.

- In Mabinogi the wandering merchant Price helps you try to find the missing ex-paladin leader Redire, it is later revealed that Price IS Redire.
- In Paper Mario 64, in what appears to be a similar example to the Secret of Mana example below, Mario comes back to town from Shooting Star Summit and told that Merlon is looking for him. When he knocks on the door, he'd told that Merlon is out. If he tries again, he is again told that Merlon is out, but the door opens, knocking him down. A man in a robe comes out, and when Mario gets up, they go inside, he reveals himself to be Merlon.
- Mario is trying to get to Dry Dry Ruins. He meets with a mouse called Sheek. Mario may part with an item to be told that Moustafa knows how to get there.

Upon following these directions, Mario arrives to find... Sheek! And he was Moustafa all along!
- In the mainstream Pokémon games, there are certain characters who would often help the protagonists throughout the story (Pokémon Red and Blue's Blue although he's also The Rival, Pokémon Gold and Silver's Lance, Pokémon Ruby and Sapphire's Steven, Pokémon Diamond and Pearl's Cynthia). Unless you know the plot of each game already, it would take much later until you find out that they are actually the Champion. In Pokémon Black and White, however, the identity of the Champion, Alder, is flat-out revealed to the player before endgame, because he actually introduces himself to the player the very first time they meet. Given what happens later, this is probably intended. Pokémon Black 2 and White 2 returns to the format with Iris showing up and helping the player character. She is already familiar from the previous game, but it isn't revealed until the end that she's now the champion. Continued in Pokémon X and Y with Diantha, although her less prominent role in the story makes her more of a Chekhov's Gunman.
- Secret of Mana: Sage Joch (or Sage Jerk as the fans like to call him) does this, sending the party out on five different sidequests before revealing that he was the person they were looking for all along.
"Go away! The sage is out!"
- The next game in the series, Seiken Densetsu 3 has a similar sequence in which the party needs to find a legendary (and tiny) strategist. The old man in town tells them that he's not in this place, and suggests they ask around. After a long fruitless search, they come back only to be told that the old man is the strategist. Justified with "I was walking around at the time, so I wasn't in any place". And then the town mocks them for their gullibility. *grumble*
- Shenmue 2: Ryo is looking for the leader of a Shaolin monastery and is told by a girl that he should look around the place for clues to understand the monks' beliefs and that only then will the master reveal himself.

- In Sonic the Hedgehog (2006), there's a mission where you're told to find a captain. Thing is, the person who gives you the mission actually IS said captain.
- As is to be expected from this game, it's hilarious. Since you start in front of the quest-giver when the "Find the captain" game starts, it's also not unknown for players to rush through the dialogue, accidentally choose "Yes" when they're asked to confirm their choice for the captain, and win without realizing what the hell they did.
- Star Wars Legends:
- In The Force Unleashed, the protagonist is assigned to kill a Jedi. Later on in the game, it's revealed that the Jedi survived, but lost his sight as a result of the battle.

At the end of the game we find out the Jedi suspected it was the protagonist but chose to help him anyway.

- Time Crisis 5 has Robert Baxter, the protagonist of Time Crisis II, help out the heroes in hunting down Wild Dog and a traitor from the VSSE, the latter of which they suspect to be Keith Martin, also a Time Crisis II protagonist. Not only is Keith not the traitor, but the real traitor is Robert.
- One side quest in Vampire: The Masquerade Bloodlines has the player hunting down a demon by the name of Zygaena. A drug dealer in the local bar will arrange a meeting in a nearby warehouse, but only if you tell him that you're planning to kill Zygaena. Guess who shows up in that warehouse.
- In A Very Long Rope to the Top of the Sky, Walker was supposed to deliver an apology from King Albus to Ivy, but didn't realize that Ivy was the nice lady giving him directions!
Walker: I'm supposed to deliver this to Ivy.
Ivy: I'm Ivy.
- In The World Ends with You: Neku spends much of the game looking for The Composer after partnering up with Joshua, who wants to take down the Composer and usurp his position. In the third week, Beat wants to become Composer so that he can end the Reaper's Game and bring Rhyme back to life, so the hunt for the current Composer resumes. After defeating the Final Boss, Neku learns that Joshua was actually The Composer all along, and he'd manipulated Neku into doing his bidding. Cue Neku's Heroic Blue Screen of Death.

- In Moon over June, an older man sternly lectures a twenty-something woman about nosing through the office of the new professor; then he spots the photo of recently minted and hired Dr. Hatsuki Hasegawa, PhD and her daughter on the desk.
Guy: I Say! Did you bring in a picture of yourself for the professor? That is really, really inappropriate, young lady!
Hats: Must... not... murder... brain-damaged... colleague...
- In Not a Villain, Paddy thinks Danni's avatar is a tribute to the late ballerina Daniella Morretti. Danni has to clarify that she actually is Daniella Morretti and is still alive.
- Stand Still, Stay Silent: After a battle during which Onni provided a lot of magic support long-distance, Reynir decides to check on him via the mage-exclusive Talking in Your Dreams system. Once in Onni's protected area, he sees an owl sitting on a tree branch, assumes it's Onni's luonto and goes to pet it while asking it if it knows where "his human" is. With the extra info that Onni has been shown to be able to take his luonto's form in a previous chapter, guess who Reynir turns out to actually be petting and calling "little buddy".

- Aang in the first episode and a half of Avatar: The Last Airbender. The others weren't actually looking for the Avatar, but their reactions when they find out that that's him definitely fit. The kid had his reasons for trying to hide it.
Katara: Why didn't you tell us you were the Avatar?
Aang: Because... I never wanted to be.
- Subverted at the start of Book 4 of The Legend of Korra. The owner of the underground fighting ring seems to recognize Korra as the Avatar, but she denies it.

When Jazz uses the Fenton Peeler to expose him, Jack and Maddie promptly demand to know what he did to "their boy", to which Dark Danny informs him he is their boy, followed by a "The Reason You Suck" Speech about their Parental Obliviousness:
Dark Danny: [evil laugh I am "your boy"! What kind of parents are you, anyway? The world's leading paranormal experts, and you couldn't figure out your own son was half-ghost! Hello! Danny Fenton. Danny Phantom. Ever notice the similarities?
- Inverted in the Justice League episode "A Better World": The Justice League are trapped in an Alternate Universe ruled by Knight Templar Evil Counterparts to the league, and are ambushed by the army.

Moe's bar, temporarily tremendously popular due to Moe's appropriation of Homer's drink, the "Flaming Homer", possesses a man going by "Hugh Jass", the fake name that Bart chose to prank the bar with.

- In Teenage Mutant Ninja Turtles (2003), Leo's first meeting with The Ancient One is a textbook example of the trope. Fortunately he figures it out on his own.
- This happens in an episode of Teen Titans: Robin went to study martial arts under a mysterious teacher called The True Master. To get to The True Master, he must climb a tall mountain before sundown. Along the way, he repeatedly encounters an old woman who requests his help carrying her things up the mountain, which he refuses because he's in a hurry. When he arrives, it turns out she is The True Master, but there's no implication that she concealed her identity on purpose. Robin just never thought to ask. You see, that was one of her lessons.
- Master Dashi in Xiaolin Showdown. When Omi traveled to the past to find him, he tried to ask Dashi if he knows him, without knowing he was talking to him. Granted Dashi didn't tell him, either. He tried to hide his identity, but a younger version of Dojo gave him away.
- Nestor Makhno, the Ukrainian anarchist revolutionary, caught a group of German officers going to a party held in their honour by Ukrainian landlords, who had welcomed the invading Germans.

At the end of the meal, a toast was offered to the capture of the dreaded anarchist Nestor Makhno. Makhno drank off the toast and announced, "I am Nestor Makhno." In the silence and horror which followed, Makhno tossed a bomb into the room as he and his men leaped out the windows and escaped.

He says his name is Joseph and he has lost his son. "How will you recognise your son?" "He has nails in his hands and feet." "Father!" "Pinocchio!" (Geppetto is a diminutive for Giuseppe, the Italian form of Joseph.)
- At one point right after confederation, Sir John A Macdonald (the first Prime Minister of Canada) was at a diplomatic reception in Washington, D.C., where he struck up a conversation with an American senator's wife.

Sir John A agreed with her on both points, at which point the senator himself wandered over and fully introduced him.

- Inverted in a story with Walt Disney. While he was secretly scouting out land for a second theme park on the US east coast in the mid 1960s, he'd travel under fake names. Eventually he was recognized (since he did host a TV show at the time, it was crazy that it hadn't happened before) by a reporter who asked if he was the real Walt Disney. Walt replied with "No, but I get confused for that bastard all the time. Trust me, when I find that son of a bitch I'm really going to let him have it." Since of course the "real" Walt Disney would never swear or threaten physical harm on anyone, the reporter decided it wasn't him and walked away.

- George Washington
- Painter Gilbert Stuart had a moment with George Washington. Stuart had been invited to a presidential levee and, assuming it was run along the same lines as similar events in Europe, presumed the room full of milling, chatting gentlemen was a sort of waiting room and he would in due course be ushered into the presence. Eventually President Washington noticed an unfamiliar guest wandering around talking to no one and, like a good host, went over and introduced himself. Stuart, it is said, never entirely recovered from this experience.
- A man was riding along when he saw an officer who was ordering soldiers to lift timber but not doing anything to help them. The rider asked him why he was just standing there; the officer sneered, "Why sir, I'm a corporal!" Upon hearing this, the stranger promptly dismounted and spent several minutes helping the men move the timber. As he was about to ride off, he turned to the pompous corporal and quietly said, "The next time you have a piece of timber for your men to handle, corporal, send for your commander-in-chief."
- There is a story concerning Peisistratus, a politician from Ancient Athens, who was walking through the Athenian countryside and got chatting with a farmer. Not realising who he was talking to, the farmer spent most of the conversation criticising Peisistratus' policies, calling him a tyrant and complaining about unfair taxes. Peisistratus listened patiently, then asked "What do you get from the land you farm?" The farmer replied: "Nothing but aches and pains. If only Peisistratus and his tax collectors would take their fair share of those." Peisistratus, having a good sense of humour, decreed that the farmer need never pay taxes again.
- British artist Sir Stanley Spencer was invited to receive an award at a ceremony in London. While getting off the train at Euston station, a gentleman mistook him for a porter and asked for help carrying his bags. Stanley obliged and helped the man carry his bags across London. When he arrived at the ceremony that evening, the award was handed to him by the gentleman he'd helped earlier that day.
- There is an almost certainly apocryphal story of various great leaders such as Napoleon or Peter the Great going out into his army disguised as a common soldier. He met a savvy veteran who shared that he had gotten short on money and taken his sword to a pawn shop, with the plans to redeem it as soon as he got paid. Until then, he had only the hilt of a sword attached to a stick that went into his scabbard. Later that day, Napoleon returned undisguised to hold a surprise inspection. He found a soldier who did not pass, then turned to the veteran and ordered him to cut down his comrade. The veteran, knowing he faced punishment if anyone knew he had pawned his sword, cried out "May God turn my sword to wood so that I need not do this thing!" He then drew his sword hilt which had a wooden blade. The next day, he received a beautiful new sword and a note saying "This one will get you more at the pawn shop," signed Napoleon.

- Simone Missick, who plays Misty Knight in Luke Cage (2016), recalls once being asked by a cashier, "Have you seen Luke Cage? You look like the woman on the show," to which she replied "Is it good?" and he said "I like it".
- In another joke, an officer moved to a Pentagon job finds himself overloaded with bureaucratic red tape. Worse, he notices that a young lieutenant in the next office is finishing far more paperwork in far less time. Swallowing his pride, he asks the lieutenant his secret, which turns out to be "Just stamp everything 'Route to Major John Smith' — somebody around here is bound to have that name and rank". One guess who that turned out to be....
- The Secret Service was protecting President Lyndon Johnson during a trip to Canada. A particularly keen agent stopped a middle-aged man who was about to walk into the house at Harrington Lake where the President was staying. "Who are you and where are you going?"

- An Athenian named Aristides, nicknamed "the Just" is said to have once been approached by a man who didn't recognize him who wanted help writing the name Aristides on an ostrakon (a piece of broken pottery that Athenians used as scrap paper) as his vote for who to ostracise. When asked why he wanted Aristides ostracised, the stranger replied that he'd never met him, but was sick of hearing him called "the Just". Being an honest man, Aristides wrotes his own name on the ostrakon, and ended up ostracised, though presumably by more than one vote.
