Some people just don't like their names. That's fairly reasonable--you don't exactly get a choice in that matter--but some find a way around that by going by a different name, usually their middle name or by rearranging their names.

In fiction, this can often be used to disguise the true identity of a character, and when their full name is revealed it is generally considered a major plot or character point. Also often used as a ShoutOut, a HistoricalInJoke, to reveal that EveryoneIsRelated once again, a character's use of a FullNameUltimatum, or to make a point by revealing a MeaningfulName.

[[folder:Anime and Manga]]
* ''Manga/DeathNote'' has L ([[spoiler:Lawliet]]), BB ([[spoiler:Beyond Birthday]]), Near ([[spoiler:Nate River]]), and Mello ([[spoiler:Mikael Keehl]]), and it's a major plot point that Kira doesn't know their names. Or L, in the case of BB. It's confusing.
* In ''Anime/PuellaMagiMadokaMagica'', "Kyubey" is revealed [[spoiler:to be the shortened name of his species: the Incubators.]]
* Brief[[spoiler:ers Rock]] from ''Anime/PantyAndStockingWithGarterbelt''.
* In ''Manga/FairyTail'', the BigBad Zeref's most powerful [[OurDemonsAreDifferent Etherious]] and Tartaros' is known simply as "E.N.D.". At the end of the Tartaros arc, his full name is stated to be [[spoiler:Etherious Natsu Dragneel--TheHero of the series]].
** Later on, the full name of Zeref himself is revealed in his StartOfDarkness chapter: [[spoiler:Zeref Dragneel, [[LukeIAmYourFather Natsu's older brother]]]].
* ''Manga/OnePiece'': One of the reasons why Corazon [[spoiler:(Donquixote Rocinante)]] tried to keep Trafalgar Law away from [[spoiler:his older brother]] Donquixote Doflamingo was because of his full name, which, had Doflamingo learned of it, would have gotten Law killed. Law himself was instructed by his parents to keep it secret -- [[spoiler:as it's Trafalgar '''''[[SecretLegacy D]].''''' Water Law]].
* This happens twice during the KCGC arc of ''Anime/YuGiOh''. Early on in the tournament, Seto Kaiba gets suspicious of a duelist named Zigfried Lloyd; upon investigating, Kaiba discovers that he's actually Zigfried von Schroeder, the son of Kaiba's father's rival. After Kaiba deals with him, a young duelist named Leon Wilson goes on to duel against Yugi. After the duel starts, one of Kaiba's {{mooks}} discovers that Leon Wilson is actually Leon von Schroeder, Zigfried's little brother.
* While he only appears in a couple of chapters in ''Manga/AttackOnTitan'', [[spoiler:Eren Kruger]]'s first name isn't given until just before his death, as it's [[spoiler:the name of the main character. It's implied Eren Yeager was named after him, as Kruger's the man that saved Eren's father Grisha]].
* In ''Manga/DrStone'', Senku's surname is revealed to be Ishigami. In the same chapter, [[spoiler: it's also revealed that the name of the village he's been living by for the last six months is Ishigami Village.]]

* The "Shadowplay" arc in ''ComicBook/TransformersMoreThanMeetsTheEye'' reveals the name of the senator who supported Orion Pax and modified him to carry the Matrix of Leadership, setting him on the path to becoming Optimus Prime: [[spoiler:Shockwave.]]
* After Dracula kills the would-be vampire slayer Hans in ''Comicbook/DraculaLives'', his pregnant lover Rachel swears that her son or his children will one day destroy him, and reveals her full name in the process.
-->''So I swear... '''Rachel van Helsing'''.''
* The "All New, All Different" Comicbook/XMen had been running for quite some time before we learned Character/{{Wolverine}} was named Logan (when he visits his old friends [[Comicbook/AlphaFlight Mac and Heather Hudson).]] Nightcrawler observes that he had never told him, and Logan says, "YouNeverAsked."
* In ''ComicBook/YTheLastMan,'' [[BadassIsraeli Alter]] has never revealed her real name due to an old Jewish superstition (her elder siblings died as babies, and keeping her name secret would protect her from [[TheGrimReaper the Angel of Death]]). Right before she thinks she's about to die, however, she reveals that it's [[spoiler:Yedida]].
** PlayedWith: Agent 355 reveals her name to Yorick, but the reader doesn't know what it is. WordOfGod says there are hints to it in the series. {{Fanon}} usually guesses that it's "[[spoiler:Peace]]," since you see it written on [[spoiler:her gravestone]].
* In ''ComicBook/KidEternity,'' the protagonist was only known as "the Kid" for decades, but when Creator/DCComics decided to do some CanonWelding with ''ComicBook/{{Shazam}}'' he was revealed to be Christopher "Kit" Freeman, Freddy Freeman's long-lost brother.

[[folder: Fan Works]]
* In ''Anime/FullmetalAlchemist'' fanfic ''FanFic/BuildYourWingsOnTheWayDown''  Hughes thinks Edward's blond university friend, Gabby seems familiar until it hits him:
-->'''Hughes''': [[spoiler: ''Catherine Armstrong?'']]
* ''FanFic/ThePiecesLieWhereTheyFell'': [[spoiler:Chapter 28 reveals that "Page Turner" is a pony-style alias. When speaking to Captain Memorizing Gaze, she gives her name as Lamella. Then, in chapter 30, it's revealed that her full name is Lamella Armor the Tenth.]]

[[folder:Films -- Animated]]
* In ''Disney/{{Tangled}}'', when Flynn and Rapunzel are caught in a flooding cave and it seems they might not make it out alive, Flynn confesses that he took his name from a hero in a book and that his real name is [[spoiler:Eugene Fitzherbert]].
* {{Subverted}} in ''Disney/TheSwordInTheStone,'' based on ''Literature/TheOnceAndFutureKing'' (see below). In this version Wart introduces himself to Merlin with that nickname, but adds that it's short for [[KingArthur Arthur]], rather than saving that fact for the end.
* ''WesternAnimation/TheLegoMovie'', Wyldstyle later reveals that she actually uses that as her nickname, as she doesn't like her real name, [[spoiler:Lucy]].

[[folder:Films -- Live-Action]]
* In ''Film/TheDarkKnightRises'', the closing montage reveals that John Blake's first name is [[spoiler:Robin]]. In this case the name is simply symbolic, since he's a CanonForeigner and no one in the ''Franchise/{{Batman}}'' mythos has that name anyway.[[note]] The Robins' real names are Dick Grayson, Jason Todd, Tim Drake, Stephanie Brown, Damian Wayne and Carrie Kelley (sorta), if you're wondering.[[/note]]
* In ''Film/MeetTheParents'', it's an important plot point that Greg's real name is not Gregory, but Gaylord.
* At the end of ''Film/{{Memento}}'', it's revealed that [[spoiler:Teddy]]'s real name is John Edward Gammell, meaning that he too is a John G, and therefore a candidate for Leonard's hit list.
* This has happened to Franchise/SherlockHolmes three times (-although twice in Films):
** During the climax to Creator/TheAsylum's {{Mockbuster}} ''Sir Arthur Conan Doyle's Sherlock Holmes'', Holmes's villainous brother repeatedly refers to him as "Robert". Holmes later reveals that his full name is "Robert Sherlock Holmes" and that he goes by his middle nwame because "who would remember a detective named Creator/RobertHolmes?"
** In the made-for-TV-movie ''Sherlock Holmes in New York'' (starring Creator/RogerMoore) Holmes, upon learning that Irene Adler has a young son named Scott, tells Watson that his full name is William Sherlock Scott Holmes. Similarly, in ''Series/{{Sherlock}}'', Holmes reveals that to be his name. That is actually as piece of Fanon: Holmes once used the pseudonym William Escott. Sherlockian writers took that as a play on William S. Scott and surmised that he was named after the writer William Sherlock.
* Another Holmes example from ''Film/YoungSherlockHolmes''. The villain, Rathe, is seen to have survived at the end of the movie and signs into a hotel under the name "Moriarty".
* A comic example comes from ''Film/RobinHoodMenInTights'', during the ceremony to [[spoiler:marry the unwilling Marian to the Sheriff. "We are here to witness the marriage of Mervyn, Sheriff of... ''Mervyn?'' Your name is ''Mervyn?''" Cue snickering onlookers and an embarrassed Sheriff whenever the Abbot says his name in the contex of the ceremony.]]
* ''Film/PitchPerfect'': During a round of telling secrets, Fat Amy reveals that her real name is [[spoiler:Fat Patricia]].
* In ''Film/TheRockyHorrorPictureShow'':
-->'''Frank''': Dr. Scott-—or should I say, Dr. ''von'' Scott!
* In ''Film/KillBill,'' the Bride's name is censored out for the first movie and a half; other than that, she's usually addressed by her old code name, "Black Mamba," or "Kiddo" by Bill. Only halfway through the second movie do we learn that her real name is [[spoiler:Beatrix Kiddo]].
* Played for drama in ''Film/StarTrekIntoDarkness'':
-->''"John Harrison was a fiction created the moment I was awoken by your Admiral Marcus to help him advance his cause, a smokescreen to conceal my true identity. My name is...[[Film/StarTrekIITheWrathOfKhan KHAN]]."''

* In the ''Literature/ChroniclesOfTheKencyrath'' stories, the main heroine goes by the name Jamie, with the few among her people who know that her full name is Jamethiel appalled that she was given the name of the most infamous woman in the Kencryaths' history.[[spoiler: They'd be even more appalled to learn that she's named after her mother]]
* ''Literature/{{Discworld}}'s'' Cut-Me-Own-Throat Dibbler, or just plain Throat, with his real name being [[spoiler: Claude Maximilian Overton Transpire Dibbler]].
** Vimes had previously only known Lord Vetinari by his last name; although it was given to readers beforehand (it's Havelock, which might be an UnfortunateName elsewhere but this is Discworld and it could be much worse), a rather casual GivenNameReveal by Sybil becomes actually unsettling to Vimes. He had never thought of the Patrician having a first name, or of anyone knowing him well enough to call him by it.
** Vimes' own first name, Samuel, only gets its first mention in the last couple pages of ''Discworld/GuardsGuards'', when he introduces himself to a friend of Sybil's who remarks that it's a trustworthy name.
* In the ''Literature/{{Goosebumps}}'' book "A Night In Terror Tower", Sue and Eddie learn that their full names are [[spoiler: Princess Susannah and Prince Edward of York]].
* This is a big plot point in ''Literature/HarryPotterAndTheChamberOfSecrets''. Harry comes upon a mysterious book that turns out to be the diary of Tom Riddle, who received an award for services to the school fifty years ago around the same time that students were getting attacked in a series of events similar to those of the present, which Tom tells Harry was for helping to stop the attacks. At the end, Ginny lying unconscious in the Chamber in question and Tom Riddle is right there. What does Tom do? He picks up Harry's wand, uses it to write out his full name (Tom Marvolo Riddle) in midair, and then rearranges the letters to spell out the message "I am [[spoiler:Lord Voldemort]]".
** PlayedWith in later books: Harry finds a note by left for Voldemort by "R.A.B.," but doesn't know who it is. In this case he already knew of the person, but lacked a ''middle'' initial: it's [[spoiler:Sirius' brother, Regulus Arcturus Black]].
* Strider in ''Literature/LordOfTheRings'' is revealed early on to be Aragorn the rightful king of Gondor.
* In the [[FirstEpisodeSpoiler first installment]] of ''Literature/TheQueensThief'' series, Gen presents himself to other characters [[UnreliableNarrator and the reader]] as a lowly street thief. Part of the reveal of his actual identity as a GuileHero prince involves the fact that his full name is the aristocratic sounding Eugenides (which in Greek basically means "well born"/"nobly born").
* Literature/JohnnyTremain's real name is Jonathan Lyte Tremain. His mother was the BlackSheep of the upper-class Lyte family, and he has a valuable OrphansPlotTrinket inherited from them. However, when he tries to cash in on this connection, it doesn't go well.
* In ''Literature/ATreeGrowsInBrooklyn'', Francie goes to a charity Christmas concert where a rich girl named Mary is supposed to give away a doll to any "poor little girl" in the audience who is also named Mary. The announcer asks any Marys to come up onto the stage, but even though there are "at least a hundred Marys in that audience," they're all too proud to accept the title of "poor little girl." Francie can't stand to see the doll go to waste and so she raises her hand and lies that her real first name is Mary, enduring another speech about the rich girl's unselfishness and the contempt of all the other girls, and after getting the doll she feels so guilty she decides that when she makes her confirmation, she'll take the name Mary so she won't be a liar anymore. But when she suggests this to her mother, her mother tells her that although she's called Francie after a friend of the family, she was also named after her grandmother and was actually christened Mary Frances.
* In ''Literature/GalaxyOfFear'', Uncle Hoole never reveals if he has more than one name until ''Army of Terror''. [[spoiler: He accidentally [[GhostPlanet wiped out all life on a planet]] under his first name, Mammon. When they all went to that planet, the vengeful wraiths chanted "Mammon! Murderer!", to the confusion of the Arrandas.]]
* In ''Literature/TheBartimaeusTrilogy'' [[IKnowYourTrueName birth names]] have power, which is why magicians stop using them and eventually take on pseudonyms. [[ParentalSubstitute Mrs. Underwood]], however, continues to call her husband's apprentice "[[ChildProdigy Nathaniel]]" long after she's supposed to...which allows [[NobleDemon Bartimaeus]], Nathaniel's unwilling {{Familiar}}, to overhear and get a bit of leverage on his master.
* The kid novel ''101 Ways to Bug Your Parents'' features a BigManOnCampus called [[TheAce Ace]], whose real name is unknown to any of his classmates. Eventually he and the protagonist are both waiting to talk to the principal and Ace gets called in by the name [[spoiler:[[MrSmith John Smith]]]]. The protagonist is rather stunned while Ace seems embarrassed.
* In ''Literature/{{Holes}},'' the Yelnats family has been cursed for generations since one of their ancestors stole a pig from an old Gypsy woman named Madame Zeroni. Eventually, the curse sends Stanley Yelnats IV to a juvenile detention camp for a crime he didn't commit. All the boys there use nicknames, though he eventually learns their real names as well. Though Stanley doesn't realize it, this lets readers catch on to the fact that [[spoiler:Stanley's friend, Hector "Zero" Zeroni, is the Gypsy's descendant]].
* ''The Gates of Rome'' by Conn Iggulden is about young Julius Caesar and his best friend Marcus, who is revealed to be [[EtTuBrute Marcus Brutus]] in the very last line.
* In ''Literature/TheOnceAndFutureKing,'' the main character is only known as "[[OnlyKnownByTheirNickname Wart]]" throughout most of the first book, though we're told that this nickname approximately rhymes with his name. Given that he's tutored by Merlyn and pulls a sword from the stone, it's not much of a twist when the last line names him as KingArthur. (See ''Disney/TheSwordInTheStone'' above.)
* In ''Literature/TheTraitorSonCycle'':
** The Red Knight has faked his death and has been going by this nickname for five years until [[spoiler:his brother]] identifies him by name and surname. Red Knight's slow return to his given name marks his character development.
** The Wyrm of Erch being named as [[spoiler:Lot]] marks the point where the characters finally start to learn something more about the underpinnings of the conflict they're embroiled in.
* In ''The Turbulent Term of Tyke Tiler'' by Gene Kemp, Tyke's narration frequently refers to "my real name, the one I hated". At the very end it turns out to be [[spoiler: Theodora; the first indication that [[SamusIsAGirl Tyke is a girl]].]]

[[folder:Live-Action TV]]
* ''Series/BigWaveDaves'': The character Jack Lord legally changed his name to honor the lead actor of ''Series/HawaiiFiveO''. It is eventually revealed that his original name is Earnest Hemingway, "[[NoodleIncident but that's a whole other story]]."
* ''Series/{{Bones}}'': Brennan learns that her parents were con artists who moved around a lot, and that Temperence Brennan isn't her birth name. It was originally Joy Keenan. Interestingly, both of those names seem to describe her well. As a girl, she was, presumably, happy and cheerful. Losing her parents and her brother has resulted in her keeping a lid on her emotions, hence the "temperance".
* In the 1981 TV series ''Bret Maverick'', the editor, publisher, and main reporter of the newspaper in little Sweetwater, Arizona was known as M.L. Springer. It is revealed early on that the initials stand for Mary Lou, and the revelation is used repeatedly (when a young Teddy Roosevelt comes to town, for instance).
* ''{{Series/Cheers}}'': Carla reveals that her husband Eddie [=LeBec=]'s first name is actually Guy (pronounced Gee) when one Valentine's Day while he's on the road he doesn't send her any flowers, so the gang buys some and pretends they're from him, signing it "Love, Eddie." If they were really from him it'd be signed "Love, Guy."
* An episode of ''Series/TheDickVanDykeShow'' discusses the history of their son Richie's EmbarrassingMiddleName, ROSEBUD. It's actually [[FunWithAcronyms an initialism]] of the various names their relatives wanted Rob & Laura to name him: Robert (Jr.) Oscar Sam Edward Benjamin Ulysseys David.
* In ''Series/DrQuinnMedicineWoman'' Dr. Michaela Quinn shows up in the small town she's been hired to be the doctor of, and everyone is expecting a male doctor named Michael. Horace the WesternUnionMan admits he left the "a" off her signature sent over the wire, to save the town a couple cents of fees because no one would care what "Dr. Michael A. Quinn"'s middle initial was.
* [[DefiedTrope Defied]] in ''Series/DoctorWho''. The Doctor has never revealed his true name. This was toyed with for an entire season once, and at the last episode of the season he apparently ''whispered'' it into River Song's ear at her wedding. It is played straight quite a bit with secondary characters, however:
** Turlough is only ever called Turlough until in his final story, when it is revealed his first name is Vislor.
** River Song's original name is revealed to be [[spoiler:Melody Pond, taking the other name thanks to a translation from the language of the people of the Gamma Forest. This reveals her as the child of the Doctor's Companions, and, later, the Impossible Astronaut. This makes her both the Doctor's murderer and saviour. She was (in between these revelations) also discovered to be Rory and Amy's rebellious childhood friend, Mels (who Amy named her daughter after), who regenerates into the portrayal by Alex Kingston when she gets shot by UsefulNotes/AdolfHitler.]]
** In her first appearance, Amy is introduced as seven-year-old Amelia Pond, so can go by Amy when she's older for a short while without the Doctor knowing.
** In "Utopia", we meet Professor Yana and then see the letters of his surname rearrange themselves vertically as he steps into a lift. They become an acronym of "You Are Not Alone", the last words spoken by the Face of Boe (they were delivered to the Doctor), and in the lift, the old Yana regenerates into a young reincarnation of the Master - another Time Lord (though decidedly more evil).
** in the 6th doctor episode "Timelash" the doctor accidently involves a victorian called Herbert in an adventure, at the end it is revealed that his full name is [[Creator/HGWells Herbert Wells]].
* In the ''Series/{{Firefly}}'' episode "Shindig," Kaylee's full name is revealed to be Kaywinnit Lee Frye. In TheMovie, Wash's full name is revealed to be Hoban Washburne.
* ''Series/{{Glee}}'': [[spoiler:Lucy]] Quinn Fabray.
* The first season of ''Series/{{Heroes}}'' for some odd reason had a big reveal in the final episode that one character's name was really Noah.
** Arguably not a reveal so much as the final stage in the humanization of the character, who started the show as a seemingly absolutely cold-blooded man in black but was gradually shown to be more sympathetic, complex and heroic over the course of the first season.
* ''Series/InspectorMorse'' (novels and TV show) waited until after he was dead to reveal his first name was [[spoiler: Endeavour]].
* In ''Series/ItsAlwaysSunnyInPhiladelphia'', Mac's full name was kept secret for several seasons. Then in the high school reunion episode, his name was revealed to be [[spoiler: Ronald [=McDonald=]]].
* ''Series/{{JAG}}'': Up until the season 4 episode "War Stories", none of the other main characters knew that the full name of their admiral, other than the [[OnlyKnownByInitials initials AJ]]. Which stands for is [[spoiler:Albert Jethro]].
* In an episode of ''Series/KeyWest'' we learn restaurateur [[RaginCajun Gumbo]]'s real name: Paul Beausoleil. When Seamus reacts with amusement, Gumbo replies, "What, you think my momma named me after soup?"
* In the GrandFinale of ''Series/TheNanny'' C.C. Babcock's real name is revealed as [[spoiler:Chastity Claire]].
* There was an episode of ''Series/NewsRadio'' in which Catherine Duke finds out that Bill [=McNeal=]'s first name is Evelyn, and torments him with it. (Pronounced "Eev-lyn," as he points out.)
* ''Series/NightCourt'': In separate episodes it's revealed that "Dan Fielding" isn't Dan Fielding's real, full name. First we learn that he changed his last name from Elmore to his middle name, Fielding. Then later we learn that "Dan" is completely made up: his original first name is Reinhold.
* ''Series/NorthernExposure'': regular guy Holling Vincouer reveals that his family name is actually du Vincouer, and that he's descended from French royalty - but every male in his family is a {{Jerkass}}, so he changed it to try to get away from that, which is also why he's decided not to have any offspring.
* In ''Series/OnlyFoolsAndHorses'', this is combined with EmbarrassingMiddleName at the wedding of Rodney [[spoiler:Charlton]] Trotter.
* In ''Series/RushHour'' Detective Lee does not want to tell Detective Carter his first name, but at the end of an episode Carter finds out that it is Jonathan, after making several wrong guesses, such as [[Creator/JackieChan Jackie]]. In the movies, Lee's first names are Yan Naing, so he could have just picked the closest anglicised name.
* In a Halloween episode of ''Series/QuantumLeap'', Sam investigates a haunted house with a kid who is later revealed to be Creator/StephenKing.
* ''Series/{{Scrubs}}'': In the Season 8 finale (which was originally intended as the series finale), the Janitor's name was revealed as [[spoiler:Glenn Matthews]].
* In ''Series/SexAndTheCity'', Mr. Big's name was actually just a nickname given to him because of how well-endowed he is. It wasn't until the finale that his real name was revealed to be [[spoiler:John]].
* ''Franchise/StarTrek''
** [[DefiedTrope Defied]] in the ''Series/StarTrekTheOriginalSeries'' episode, "This Side of Paradise".
-->'''Leila:''' You never told me if you had another name, Mister Spock.
-->'''Spock:''' You couldn't pronounce it.
** ''Series/StarTrekDeepSpaceNine'': A plot point with Garak, the only name anyone on the station knows him by. When dying from a mystery condition, he tells Doctor Bashir a number of contradictory tales about why he was exiled from Cardassia. All of them seemed to have one thing in common: a man called Elim who was either betrayed by Garak or who betrayed Garak, depending on the version of the tale. When Doctor Bashir finally tracks down the one Cardassian who can help cure Garak's condition, Bashir asks him whatever happened to Elim after Garak was exiled. The answer was not what Bashir had expected.
-->'''Bashir:''' Garak mentioned an old friend of his the other day. A member of the Obsidian Order. I was wondering what happened to him.
-->'''Tain:''' Did he give you the name of this friend?
-->'''Bashir:''' He said it was 'Elim'.
-->'''Tain:''' (chuckling) Elim....
-->'''Bashir:''' Mind letting me in on the joke?
-->'''Tain:''' I can see that Garak hasn't changed a bit. Never tell the truth when a lie will do. That man has a rare gift for obfuscation. Doctor, 'Elim' is Garak's first name.
*** Also, it's later revealed that [[spoiler:Garak is Tain's son, although, as head of the Obsidian Order, Tain couldn't afford to have such a weakness that his enemies would use against him, so he had Garak's mother Mila (Tain's maid) claim that someone else was the father. In a proper world, Garak's real name would have been Elim Tain]].
* ''Series/WKRPInCincinnati'': In the first episode we meet Venus Flytrap. Later in the season we find out that that isn't his real name (surprise, surprise), it's Gordon Sims and he's an AWOL fugitive from the US Army. When Mr. Carlson goes with Venus to the Cincinnati army base to clear it up, he doesn't know that Sims is Sims' real name, he thinks that Venus Flytrap is his real name.
* On ''Series/{{Wings}}'', Fay was going to be a marry a maitre d' named Lyle Bartlett however during the ceremony she finds out that his given name is George. This turns out to be a game changer since Fay already married and buried three husbands named George.
* Quite a big deal was made in ''Series/{{Seinfeld}}'' when George discovered [[spoiler:Cosmo]] Kramer's first name.
* ''Series/SisterSister'' had a BizarroEpisode[=/=]VerySpecialEpisode where Tamera, uninterested in studying about black history, time traveled to meet various important African-Americans throughout history. Eventually she meets a boy she can relate to, as he doesn't seem to have any ambition about school or college either, only for her to change her mind when she finds out his name is "[[UsefulNotes/CivilRightsMovement Martin King]]."
* On ''Series/BuffyTheVampireSlayer,'' [[OnlyKnownByTheirNickname Oz]]'s real name (Daniel Osborn) is only revealed in passing after he's PutOnABus.
* Franchise/StargateVerse: "Rodney" is assumed to be [=McKay=]'s first name throughout his guest appearances in ''Series/StargateSG1'' and through the first two and a half seasons of ''Series/StargateAtlantis''. Then, [=McKay=]'s sister shows up for an episode, calls him "Meredith", and the rest is (hilarious) history. To be fair, though, Meredith started out as a man's name before transitioning into gender-neutral territory and, eventually, being thought of as mostly feminine.
* Vey few characters on ''{{Series/CSI}}'' know D.B.'s because he doesn't like it-it's 'Diebenkorn'. The audience found out when Julie Finn left him a note about something and deliberately used it to rib him-partly for calling her Jules, which she also hates.
** On ''{{Series/CSI NY}}'', it was something of a surprise to the rest of the team when Mac's girlfriend, Christine, revealed his middle name was 'Llewlyn', which even they didn't know despite how long everyone except Jo had known him. Although, she and her brother WERE friends with Mac and Claire before both died, so it may be justified. The other characters were still surprised, though.
* In ''Series/MacGyver'', Mac's first name isn't revealed until the last season, in an episode that was probably a dream sequence anyway. It's [[spoiler:Angus.]] He doesn't like it.
* Near the end of season 3 of ''Series/{{Sherlock}}'': [[spoiler:William Sherlock Scott Holmes]], who reveals his full name in a attempt to get his best friend's baby named after him. (This is actually based on a bit of Fanon, deduced from a pseudonym that the literary Holmes once used, William Escott.) There's also a bit of a flashback that shows Sherlock repeatedly trying to guess John's middle name before giving up and getting his birth certificate from somewhere (it's Hamish). However, the audience already knew, since John stated it in a season 2 episode as a possible baby name for Sherlock and Irene (chronologically, the flashback happened before this, though).
* ''Series/QuantumLeap''
** In an early episode Sam doesn't know the name of the kid with the guitar who hangs out at his veterinarian's office, in mid 1950s Lubbock, Texas. Then Sam hears him sing "Piggy Suey," and realizes both the boy's name and what he's there to do. "Uh, [[Music/BuddyHolly Buddy]], why don't you try 'Peggy Sue' instead?"
** In another, horror themed episode (which may not have actually happened - it's complicated) a supporting character named Steve turns out to have been a young Creator/StephenKing.

* In Egyptian mythology, all gods had "[[IKnowYourTrueName True Names]]" that they guarded with their immortal lives. If someone were to find out these True Names, that person could Name the god, and have it do their bidding.
* In Literature/TheBible, {{God}} tells [[MosesInTheBulrushes Moses]] that his real name is YHWH, which roughly means "I am that I am" (or "I will be that I will be"). He notes that he did not reveal that name to any of Moses' ancestors (though The Book Of Genesis ''does'' use it; interpretations may vary).

[[folder:Professional Wrestling]]
* In the [[Wrestling/{{WWE}} WWF]] two WorkedShoot interviews Wrestling/JimRoss had with wrestlers who, during the course of the interviews, revealed their real names, which led to angles: Wrestling/{{Goldust}} (Dustin Rhodes) and Mankind (Wrestling/MickFoley). Foley's angle lasted much longer and better.

* In the musical ''Theatre/GuysAndDolls'', Sky Masterson reveals his real name (Obadiah) to Sarah Brown, then she reveals it to everyone else just before the finale.

[[folder:Video Games]]
* In ''VideoGame/CaveStory'', the {{Player Character}}'s name is revealed at the end of a long side quest filled with GuideDangIt moments that is required to achieve the game's GoldenEnding. [[spoiler:It's Quote, which fits in with the typographical ThemeNaming of another major character, Curly Brace.]] Of course, [[ItWasHisSled you're likely to have found this out already if you used an online walkthrough.]]
** After completing the game's BrutalBonusLevel but before fighting the TrueFinalBoss, you can see the name of [[BigBad The Doctor]] on a statue of him: [[spoiler:Fuyuhiko Date]].
* ''VideoGame/FiveNightsAtFreddys'' and ''VideoGame/FiveNightsAtFreddys2'' reveal the names of the {{Featureless|Protagonist}} security guards that you play as via when you see their paycheck after completing the game. The first game's guard is named Mike Schmidt and the second game's guard is named Jeremy Fitzgerald. [[spoiler:In ''[=FNAF2=]'''s Custom Night, you play as a different guard named Fritz Smith.]]
* In ''VideoGame/PokemonBlackAndWhite'', Inspecting [[OneLetterName N's]] room reveals his last name to be [[MusicalThemeNaming Harmonia]], which is [[spoiler:shared by [[AbusiveParents Ghetsis]], who later claims he is "not worthy of sharing the name Harmonia", [[KickTheDog Among other things.]]]] WordOfGod has stated that his full name is N[[spoiler:atural Harmonia Gropius]], [[AllThereInTheManual but his full name is never mentioned in-game.]]
* Doc from ''Videogame/StarWarsTheOldRepublic''. His name is only revealed at the very end. Then you can see why he never uses it.
* ''Videogame/TalesOfTheAbyss'': Guy's full name is [[spoiler:Gailardia Galan, a Malkuth noble]]. Van (Vandesdelca) and Tear (Mystearica) also have longer names revealed, but they aren't quite as revealing.
* In ''Videogame/TheWorldEndsWithYou'', Beat's true name is Daisukenojo Bito. He doesn't like being called it very much. In the ''Another Day'', he just simply finds it too long to say.
* System U-D, the Unbreakable Darkness of ''VideoGame/MagicalGirlLyricalNanohaAsPortable: The Gears of Destiny'', turns out to have once been called [[spoiler:Yuri Eberwein after it's revealed that she [[WasOnceAMan was once a human]]]].
* ''Videogame/BioShockInfinite'': Elizabeth Comstock's actual name is [[spoiler:Anna [=DeWitt=]]].
* In ''VideoGame/SuperRobotWarsOriginalGeneration: Dark Prison'', Yong's real name is [[spoiler: Gaytoba Sucheka. Apparently her house hold is not that high in the hierarchy, and that explains why she addresses Mekibos so formally, whenever he insists that they talk casually, she is completely bewildered and reject the notion.]]
* Whereas all the plot you get in ''VideoGame/TeamFortress2'' proper is "mercenaries killing each other over vague objectives," with the characters [[EveryoneCallsHimBarkeep only being known their job title]], the comics have shown the actual names of some of the characters: Soldier's name is [[spoiler: Sergeant-Barrister [[GenderBlenderName Jane Doe]] (although that almost certainly isn't his ''real'' name)]], Demoman's is [[spoiler: Tavish Finnegan [=DeGroot=]]], Engineer's is [[spoiler: Dell Conagher,]] Heavy's first name is [[spoiler: Misha (Short for Mikhail)]], Sniper's last name is [[spoiler: Mundy/Mun-Dee]], Medic's last name is [[spoiler: Ludwig]], and Scout's first name is [[spoiler:Jeremy]]. Fittingly, the names of [[DoubleReverseQuadrupleAgent the Spy]] and [[TheSpook the Pyro]] are unknown.
** When the ''VideoGame/TeamFortressClassic'' characters appear in the "Mann Co. No More!" storyline, we find out the Classic Demoman and Classic Pyro's first names: [[spoiler: Greg for Demo, and [[{{SamusIsAGirl}} Beatrice]]/Bea for Pyro.]]
* Solid Snake is known only by his code name until the end of ''VideoGame/MetalGearSolid'', when he reveals that his real name is [[spoiler: Dave]].
* In ''VideoGame/{{Undertale}}'', it's eventually revealed that [[spoiler: the character you named at the beginning isn't the player character, whose actual name is Frisk]]. This also happens right after [[spoiler:Flowey returns to his true form]]. [[spoiler:His]] name is revealed to be [[spoiler: Asriel Dreemurr]], which makes it clear that [[spoiler:he's the lost son of Asgore mentioned in the story at the end of the Neutral Route.]]

[[folder:Visual Novel]]
* In ''VisualNovel/UminekoWhenTheyCry'', Gretel's real name (Ange Ushiromiya) is extremely important to the plot. The readers know it from the get-go, but the main character (who's her brother) doesn't. [[spoiler:And considering she will die if she reveals her real name to him, she has reason to hide it.]]
* In ''VisualNovel/DanganRonpa'', Celeste's given name of Taeko Yasuhiro is critical to the third case, especially in regards to one of the last Truth Bullets Makoto collects.

* PlayedForLaughs in ''Webcomic/{{Homestuck}}''; when the [[spoiler:post-scratch kids]] are first introduced, [[spoiler:post-Scratch Bro and post-Scratch Mom]]'s names are deliberately obscured as much as possible, with the other two kids using [[LastNameBasis their last names]] or nicknames such as "Ro-Lal" and "Di-Stri". When it comes time to properly reveal their names, their name plaques are hidden a cat's tail and a tiny live pony. The next few pages later, they are revealed as Roxy Lalonde and Dirk Strider.
* PlayedForLaughs in ''Webcomic/TheOrderOfTheStick,'' when two MauveShirt Azurite soldiers go to [[YouShallNotPass hold off the enemy]] while the heroes escape. [[GenreSavvy Elan]] laments that they're sure to die, since [[NominalImportance they don't even have names]]. As they fight, the female soldier notes that she ''does'' have a name, Kazumi Kato. The male soldier is struck, apparently dying, and whispers to her that his name is Daigo...then suddenly gets better.
-->'''Kazumi:''' Do you have a last name?\\
'''Daigo:''' Yeah, but I think I should save it for an emergency.\\
'''Kazumi:''' Good idea.
** [[BrickJoke They follow up on it]] at their wedding, as they've still yet to come to such an emergency and avoid saying his full name. Still later, he ''tries'' to reveal his full name when a squad of ninja are trying to assassinate them, but only gets out "Daigo D" before being knocked unconscious.
* InvertedTrope in ''Webcomic/DumbingOfAge'', where some time after the introduction of Joyce's apparent brother Joshua, we get a ''Chosen'' Name Reveal as a major character point: [[spoiler:[[{{Transgender}} Jocelyn]]]].
* In ''Webcomic/ElGoonishShive'', Susan's [[ reveal]] that her first name is Tiffany leads to the first details of her BackStory.
* In ''WebComic/TheAdventuresOfDrMcNinja'', the titular doctor's first name remains a secret for most of the series. In a flashback episode, it's shown that Dr. [=McNinja=]'s grandfather used his name as part of a powerful spell to entrap a ghost who'd accidentally been unleashed during a simple assassination mission. Doing so deleted the doctor's name from everyone's minds except his own, and it could never be used again without undoing the spell. During the first part of the final story, Dr. [=McNinja=] gave his name to Sparklelord in exchange for help defeating King Radical; the consequences of this are in the midst of being explored. [[spoiler: His name, incidentally, is Patrick.]]

[[folder:Web Original]]
* In the ''Literature/ChakonaSpace'' 'Verse, Neal Foster has a reputation. He has hidden his full name in more than onc of his stories.
* ''Series/{{Noob}}'' has such a thing happen in two different ways to reveal a father-son connection between two of the characaters, depending whether the novels are read in parallel or not. The son's first name is mentioned at some point in the webseries, while the novel mentions his full name. Someone reveals the father's full name in Season 5, revealing the connection for novel readers. However, to keep webseries-only viewers up to speed, the father immediately shows up and brings up the son in conversation, while the following episode has a flash-back that mentions the son's first name and sheds any possible doubt on his identity.

[[folder:Western Animation]]
* ''WesternAnimation/KickButtowski'''s real first name is Clarence. It is revealed late in season one when Kick messes up and risks his friendship with Gunther. Gunther calls him by the real name as [[YouCalledMeXItMustBeSerious an indication of how much Kick has upset him]], and it is pretty much used regularly after that -- mostly by Kendall, who does it to needle him.
* ''WesternAnimation/PhineasAndFerb'':
** Candace's middle name is Gertrude -- revealed when Linda makes her promise against the Pharaoh's curse.
** Ferb's real name was ''about'' to be revealed to Vanessa when something happened that [[SubvertedTrope made her run off]].
* ''WesternAnimation/{{Recess}}'': the resident tough girl is named [[spoiler:Ashley]] Spinelli. [[spoiler:The Ashleys are the school's resident {{Alpha Bitch}}es]].
* ''WesternAnimation/TheFairlyOddparents'': In one episode, SherlockHolmes nearly reveals Timmy's parents' names. Then a book closes on them before their names are spoken.
* ''WesternAnimation/RegularShow'': In "Skips Strikes," Death and the Magical Elements go against the Skips and the park staff in a game of bowling. Skips is their best player, and Death, not wanting to lose, reveals that Skips' true name isn't Skips, threatening to tell everyone his real name if Skips participates in the bowling competition. Skips quits, not wanting his true name to be revealed, but later chooses to help his friends. Skips' real name is revealed to be [[spoiler:Walks, having changed it because he got tired of people asking him why he skipped while his name was Walks]].
* In ''WesternAnimation/TheSecretShow'', Victor's full name is revealed in one of the episodes to be Victor Thomas Jefferson Volt.
** Defied in ''WesternAnimation/TheSecretShow'' as well, as Changed Daily's real name is NEVER revealed, and is changed daily for "reasons of security." Usually to something awful, like Nincy-Nancy Lala or Hunda Von Lampgurgle. To the point where he has a dream in one episode that his name gets changed to Rock Justice.
* ''WesternAnimation/TheSimpsons'':
** Homer doesn't know what his middle initial, J., stand for. Then he finds out: it's short for [[ShapedLikeItself Jay]].
** In one episode, Flanders talks to the Comic Book Guy, who reveals apropos of nothing that his name is Jeff Albertson, "[[EveryoneCallsHimBarkeep but you can call me Comic Book Guy]]."
* On ''WesternAnimation/YoungJustice'' Comicbook/{{Robin}}'s real name ([[ComicBook/{{Nightwing}} Dick Grayson]]) is never really hidden from the audience, but Franchise/{{Batman}} prefers he keep it hidden from the rest of the Team for security reasons. The fact that [[FragileSpeedster Wally]] knows his real identity demonstrates how close they are. (In a tie-in comic Wally can snap out of a supervillain-induced HeroicBSOD by remembering that Robin trusted him with the information.)
** In season two, [[KidFromTheFuture Bart]] proves that he's from the future by casually giving away Dick and [[LegacyCharacter Tim]]'s real names. [[{{Animorphism}} Gar]] finds them kind of underwhelming.
* On ''WesternAnimation/{{Futurama}},'' Leela is being interviewed on TV and is introduced as "Turanga Leela"[[note]]Though this actually seems to be her surname[[/note]].
-->'''[[IdiotHero Fry]]:''' ''Turanga?!''
-->'''[[AsianAirhead Amy]]:''' That's her name, Phillip.
-->'''[[RidiculouslyHumanRobots Bender]]:''' ''Phillip?!''
** Bender himself once comments that [[XIsMyMiddleName Bending is his middle name]], his full name being [[RepetitiveName Bender Bending]] [[SuddenlyEthnicity Rodriguez]].
* ''WesternAnimation/HeyArnold'' made [[WiseBeyondTheirYears Arnold]]'s mysterious surname a RunningGag. WordOfGod and ([[SavedFromDevelopmentHell years later]]) ''[[WesternAnimation/HeyArnoldTheJungleMovie The Jungle Movie]]'' revealed Arnold's last name to be [[spoiler:Shortman. This is actually the AffectionateNickname his Grandpa had been calling him the entire series, meaning that his last name was actually HiddenInPlainSight this whole time]].
* ''WesternAnimation/LEGOStarWars: The Padawan Menace'', set during the prequel trilogy, features an orphan boy who stowaways to Coruscant and hides out with some Jedi younglings on a field trip. Since everyone else is wearing a name tag, he finds some letter decals and puts them on his shirt so that they say "IAN." Nobody addresses him by that name until the end of the episode, when he looks down and realizes that he made a mistake: [[spoiler:the "I" is actually an "H" turned sideways. [[CanonCharacterAllAlong His name is Han Solo]]]].
* On ''WesternAnimation/SouthPark,'' the identity of [[TheCowl Mysterion]] is deliberately left vague during his first few appearances. In "Mysterion Rises," however, Stan casually calls him "[[spoiler:Kenny]]" for a deliberately anticlimactic reveal.
** The {{Goth}} Kids are introduced in season 7, but only [[TheSmurfettePrinciple the one girl]], Henrietta, is named until season 17's episode "Goth Kids 3: Dawn of the Poseurs." The tall, curly-haired one is named Michael; the one with MultiColoredHair is named Pete; and the kindergartener is named [[OddNameOut Firkle]].
* Although WesternAnimation/{{Blackstar}} is called "John Blackstar" in the opening credits narration, he just goes by "Blackstar" in the show itself, until the last episode when his old girlfriend from Earth arrives on Sagar. His Sagarian friends are startled when she calls him "John."
* It isn't until the third season of ''WesternAnimation/TheAmazingWorldOfGumball'' that [[OnlyKnownByTheirNickname Gumball's]] name is revealed to the audience--''and himself''--to be Zach. [[spoiler:Although by the end of the episode we find this out, [[StatusQuoIsGod "Gumball" becomes his actual name.]]]]
* On ''[[WesternAnimation/TotalDrama Total Drama Revenge of the Island]],'' contestants can get points if they admit that an anonymous secret is actually about them. One of the secrets is that a contestant's real name is "Beverly." Everyone questions why that's supposed to be embarrassing...until [[OneLetterName B]] ([[GenderBlenderName a guy]]) reluctantly buzzes in.
* On ''WesternAnimation/GravityFalls'', we never learn protagonist Dipper Pines' real name throughout the entire run. It is only until the release of ''Literature/GravityFallsJournal3'' that we learn that his real name is [[spoiler:Mason]], when he talks with [[spoiler:his great-uncle Stanford (the Author of the Journals)]] between the events of "The Last Mabelcorn" and "Dipper and Mabel vs. The Future".
** Heck, it was so hidden that Jason Ritter, '''Dipper's voice actor''', didn't know about it until after the series ended!
* ''WesternAnimation/WeBareBears'': In "Citizen Tabes", after Ranger Tabes [[TenMinuteRetirement gives up being a park ranger]], she insists that the bears start calling her by her first name, which turns out to be "Dana".
* ''Franchise/LiloAndStitch'': In the ''[[WesternAnimation/LiloAndStitchTheSeries The Series]]'' episode "[[Recap/LiloAndStitchTheSeriesS1E14Fibber Fibber]]", Pleakley's mother reveals that his first name is "[[GenderBlenderName Wendy]]", which apparently means "great warrior" on his planet. Lilo and Nani were amused by this.
* ''WesternAnimation/TangledTheSeries'': "The Return of Strongbow" introduces Eugene's former partner in crime, Lance Strongbow. That turns out to be an alias, just like Flynn Rider, and Lance's real name is [[UnfortunateNames even more ridiculous]] than "Eugene Fitzherbert": it's [[spoiler: Arnwaldo Schnitz]].
