Zeta Gundam has a male lead named Kamille, who naturally hates his feminine-sounding name. He eventually falls in love with a girl named Four, who has similar issues with her name (in her case, because it signifies that she is a number rather than an individual). It becomes hilarious when you realize there never would have been a Zeta Gundam if he hadn't been named Kamille, and the AEUG probably would have lost or at the very least have a longer and bloodier war.
Ranma ˝ actually uses this as a plot point for one character: one Chinese village has a tradition that the person who gives a newborn baby its first bath must be the one to name it. Unfortunately, this gave panty stealing pervert Happosai the chance to name a baby, and since he loves women's garments so much he thought that the perfect name for a little boy would be Pantyhose Taro. Pantyhose Taro hates his name, and is on a constant quest to force Happosai to give him a new one, since Happosai is the only one who can change it. Unfortunately, his own choice of replacement first names aren't much better.
For the curious, the other names Pantyhose Taro could have ended up with (Happosai begins trying to list some alternatives in Pantyhose Taro's first story before he finally decides that he just can't think of a better name then "Pantyhose Taro"), include, between the anime and the manga, "Loincloth Shiro", "Underwear Saburo", "Cockroach Goro", "Bellywrap Shishiro", and "Heartburn Rokuro".
Bear in mind that the two things Happosai did was bathe him in the Jusenkyo Springs and name him, and he finds the name more offensive than the Involuntary Transformation bit (then again, he's well aware it's a Cursed with Awesome situation - he turns into a winged minotaur).
In Naru Taru, Shiina Tamai writes her first name in katakana (phoenetic characters) because she hates the kanji used for it, which is read as "empty husk" or "a seed that shall never sprout". It actually becomes a critical plot point near the end of the manga.
Hey, let's be fair—anyone who can get away with using the name "Fate" is gonna prefer it to anything else.
Bleach: Ichigo. Sure, the kanji reading amounts to "protects one thing" but the name is also homonymous with "strawberry" (and his hair is orange). Even worse, it's also a girl's name. It doesn't help him maintain a badass image. Characters, and even the manga-ka in chapter titles, are not above exploiting this. He's even called "Berry-tan" to his face by Mashiro. Lampshaded when he first meets Ikkaku who takes note of his name because they share "Ichi-" as part of the name, concluding it's an awesome, lucky omen for both of them. Ichigo observes that he's not used to that kind of reaction when admitting what his name is.
Run-Run/La-La in Mahoujin Guru Guru is utterly embarrassed by her name, and can get violently angry if people constantly repeat it or, worse, sing it. She will also go do all in her power to prevent people who don't know her name from ever learning it and is annoyed by Nike's persistence in the matter.
The main character of the manga Okama Report is named, well, Okama, which more or less means "gay guy."
In the Read or Die OVAs, Nancy "Miss Deep" Makuhari is embarassed by her Western first name and prefers to go by her code name.
Though she also finds her code name a bit embarassing as well, as she muses that it sounds like a porn star's name.
In the original Japanese version of Dragon Ball (the original), Bulma hesitatingly says her name when Goku asks what it is. This is because she original thought her name was embarrassing because of what it sounded like (in the manga; in the anime, Goku just though it was a "funny name"). All of this got lost in both the Vancouver dub, and in Funimation's redub. In the original, Bulma is called Buruma, which is a Japanese pronunciation of "bloomers", a type of women's underwear (compare her son Trunks and her father Dr. Briefs).
Then there's Goku's original name, Kakarot, used for his original purpose, when he was sent to Earth to cleanse all life from it. He rejected that name after rejecting his mission, but Vegeta and a few villains still refer to him by that name, even though he'd rather they not.
Hanai from Ookiku Furikabutte has "Azusa", which is commonly given to girls, for his first name. He hates it so much that he makes his own mother call him by their family name instead.
In Bakugan Dan's last name is "Kuso". "Kuso" essentially means "shit". It's odd since the series is Japanese so it's not a Critical Research Failure, and it's a kid show at that. note Although Japan is very lax with strong interjections and seems to have little, if any concept of "cuss words". You can find various words that translate to "damn" and "shit" used in children's anime quite often.
Durarara!! has a running gag of people making fun of Mikado Ryugamine's extremely pretentious name (lit. "The Emperor of Dragon Peak").
At least one person thought it was a really awesome name. Most people, however, (including Mikado himself) want to ask Who Names Their Kid "Dude"?
Juliet Nao Zhang of Mai-Otome strongly dislikes her first name, and everyone except Shiho (who strongly dislikes her) and some of her gang members call her "Nao".
Gou Matsuoka from Free! is considered to be referred to by her first name due to having a boy's name. She wants to be called Kou, as it sounds more feminine, but no one else calls her by that name.
Strangely enough, both of the main characters in part 7 of Jojos Bizarre Adventure: Jonathan Joestar (who changed into Johnny specifically because of the nickname Jo Jo) and Iulius Caesar Zeppeli (yes, that Julius Caesar).
In various old Finnish radio shows hosted by Pertti "Spede" Pasanen, the parrot G. Pula-aho prefers to be called as such. In a later episode, he is forced to reveal his first name to the police: Gunhild (a female name). According to him, a baby parrot is so small, that even with a magnifying glass you can't tell it's gender.
In Preacher, Bad Ass Irish vampire Cassidy goes by his last name. His first name: Proinsias. (Apparently pronounced "Francis", but that wouldn't help his image any.) "It's... a perfectly respectable Gaelic name... Oh Jaysis, Jesse, don't tell anyone!"
Well, it's the Irish Gaelic equivalent/translation of "Francis", but it's actually pronounced "pryne-SHEE-as". Yeah, I wouldn't tell anyone either.
Jughead and Jellybean Jones (from Archie Comics) are named Forsythe and Forsythia respectively. In one story, Jughead goes out of his way to keep Jellybean's name from being revealed to the public via billboard, and both characters have had stories where people who try to call them by their real names ended up with misfortune.
Oddly, in Jughead's case, his distaste for his name is partly because any girl who hears it thinks it's suave and romantic and starts chasing him.
Even odder, Reggie seems to suffer a string of continuous bad luck whenever he mentions Jellybean's real name, making him warn everybody not to say it, thinking it's a curse.
In the Tintin comics, the first name of Captain Haddock is only mentioned once (in the last finished album, no less). The Captain gets momentary amnesia after getting hit in the head, and when told by Tintin that his first name is Archibald he snarks and says that the name is ridiculous. Which might explain why nobody ever calls him by his first name otherwise.
Then again, few people gets called by their first name in the series, except Tintin, who doesn't seem to have any other name, and minor characters like Igor, Irma, and Allan.
Miracleman featured a cold hearted, stone-tough assassin named... Evelyn Cream. Wow.
Few characters in the Brit series of comics realize that the title character's name is short for Brittany.
In Le Scorpion, Hussar's first name is Aristotle. His father thought it would help him become a great philosopher.
In Death: The Time of Your Life, Foxglove's "minder" is Boris, who partly fits the trope of a Scary Black Man. Unfortunately, there are some things you can't hide from Death, so when in the course of a conversation she addresses him by his real name, Endymion, he hastens to point out to everyone present that he really prefers to be called Boris.
Quasar's first name is Wendell, and whilst he doesn't exactly hate it, he was apparently called Elvis (his middle name) in college.
Gen13 team member Grunge has the unenviable first name Percival. Naturally, he goes by his middle name, Edmund. Being that this isn't much of an improvement, he prefers the nickname Grunge.
At one time, Sonic the Hedgehog stood revealed to have a very embarrassing first name and his parents tried to mitigate it by calling him by his equally-Embarrassing Middle Name "Maurice". Nowadays, neither are brought up at all, especially after writers changed hands.
In Kira Is Justice, Justin's real name is Justice. Let's say it's both suitable and ironic since he's Kira.
In this (pre-Alpha) Homestuck fanfic, Bro's first name turns out to be Calvin, with "Charles" (the name he used in the author's previous Bro fics) being only his middle name.
A Harry Potter round-robin story, "The Most Private Journal of Auror Captain Harry James Potter", features a character with the name "Liar Whore Who Sucks Men’s Screaming Souls Out Through Their Penises" — known as Lia for short. Of course, since she's a succubus, her name is more like a job description... at least until she's accidentally bound to Harry.
Ash from the Evil Dead movies. His real first name is actually Ashley... which is probably why he goes by Ash even as the clueless yuppie from the first movie.
In Quantum of Solace, the agent sent to pick up James Bond in Bolivia only gives her name as "Fields," and deflects further questions about it. Given that the credits give her first name as Strawberry, it's hard to blame her.
Cobra's title character is actually named Marion Cobretti. He lampshades it at one point, when he explains "I'd prefer something a little tougher... like Alice."
Boss Spearman in Open Range doesn't reveal his actual name, "Bluebonnet," until he thinks he's facing his death.
And then of course, there's Michael Bolton, poor put-upon office worker (and not the "no-talent ass clown") from Office Space. "Why should I change my name? He's the one who sucks."
In real life, the singer's name was anglicized from "Bolotin."
In The Wrestler, Randy "The Ram" Robinson hates being called by his real name, Robin Raminski, partly because it's an embarrassing name and partly because he can't give up his wrestling alter-ego.
Stripes: "The name's Francis Soyer, but everybody calls me Psycho. Any of you guys call me Francis, and I'll kill you."
Lighten up, Francis.
In Seven Brides for Seven Brothers, the lumberjack brothers were all given names from the Bible in alphabetical order. Since there was no "F" name, the sixth brother got stuck with Frankincense. He violently insists on being called Frank.
In Ten Inch Hero, Priestly's first name is Boaz and Tish is short for Platisha. None of their friends know this about them because they hate their given names so much. Priestly's boss doesn't even know his first name.
Rubber Duck from Convoy reacts with embarrassment when he is addressed to by his whole real name which is Martin Penwald.
Roy O'Bannon from Shanghai Noon hides his whole real name, too, which happens to be Wyatt Earp. Judging by Chon Wang's reaction upon this, it is a truly embarrassing name.
In Tangled, the thief Flynn Rider's true name is Eugene. He changed his name because he thought it wasn't cool enough.
Glory Road has Evelyn Cyril Gordon, who went by E.C., often elided to "Easy", and later by "Scar" after he was injured in the Vietnam War. Which got misheard by his employer, the Empress of the Nine Universes, so he became "Oscar".
The Puppet Masters has "Sam", a secret agent who goes through several false identities. Only late in the novel does he go right up to his father and ask, "Dad, why did you name me Elihu?"
This is a staple of P. G. Wodehouse's Jeeves and Wooster books. This is likely due to Pelham Grenville Wodehouse disliking his first two names intensely, hence his use of initials.
Jeeves' first name was eventually revealed to be Reginald. This is shocking not because the name doesn't suit him, but because we always assumed Jeeves didn't have a first name. Brinkley/Bingley's tendency to call him "Reggie" made matters even more embarrassing for all concerned.
In "Big Money", the rich man's name is T Patterson Frisby. What does the "T" stand for? Torquil. Naturally, he doesn't use it, after all the bullying he got at school.
In Thank You, Jeeves, "Chuffy" Chuffnell has gone his whole life concealing that his first name is Marmaduke.
In one book, Lemuel Gingulphus Trotter goes by his initials, and has refused a knighthood because he could not stand the thought of being "Sir Lemuel". At one point, Bertie and Jeeves unsuccessfully try to blackmail him over this.
You know a guy hates his name when he prefers being known as Captain Underpants...
Mr. Krupp is a Hypno Fool. He doesn't know he's a superhero and vice versa.
In Little Women, Laurie's actual first name is Theodore. That's not bad in itself, but considering that his friends used to call him "Dora", it's not surprising that he went with a variation of his last name, Lawrence.
Harry Potter's Nymphadora Tonks, "who prefers to be known by her surname only" ("So would you if your fool of a mother had called you 'Nymphadora'"). While her mother Andromeda presumably uses this first name, and her father calls her "Dora," everyone else uses Tonks.
Robinette Broadhead is the male protagonist of Frederik Pohl's Heechee Saga.
Ermintrude from Nation changes her name to "Daphne" at the first possible opportunity.
Pratchett also likes inversions, e.g. Agnes in Discworld and Kirsty in the Johnny Maxwell Trilogy, both of whom are disappointed by their very ordinary-sounding names and insist on going by others.
Moist von Lipwig. He's learned to live with it, though, and Adora Belle comments that it must be his real name because nobody would choose it for their false name.
And his other half, Adora Belle Dearheart.
One Man Bucket in Reaper Man. He comes from a tribe where they name you after the first thing your mother sees when you're born, and his full name is One Man Pouring A Bucket Of Water Over Two Dogs. It's his slightly older twin brother you really have to feel sorry for, though.
Windle Poons: Don't tell me, "Two Dogs Fighting"?
One Man Bucket: Two Dogs Fighting? He'd have given his right arm to be called Two Dogs Fighting.
The very end of The Sherwood Ring reveals that Pat Thorn's real first name is one of these — Peacable, named after his ancestor.
The protagonist and titular characters of Percy Jackson and the Olympians attends by Percy, as his first name is Perseus,ironically, named after a demigod that is disliked by his father Poseidon
The 1632 series features three kids whose parents were hippies, and thus are all named after Tolkien characters (Faramir, Gwaihir and Elrond); their father later sobers up a bit and gives them the pseudonyms of Frank, Gerry and Ron so they don't get beaten up at school.
Tomboy Min Farshaw hates her full name, Elmindreda, which is most notorious as a folklore character who is shallow and flighty — not to mention very, very girly.
Another example is Zarine "Faile" Bashere, who hates her first name because to her it's a name for a woman who reclines on cushions while eating grapes. Her chosen name means Falcon.
In Lois McMaster Bujold's Vorkosigan Saga, Lieutenant Koudelka ("Kou" to his friends) and Miss Droushnakovi ("Drou" to her friends) are embarassed at their wedding when they have to publically admit to their first names, Clement and Ludmilla. (Drou continues to go by her nickname even though she chooses to take her husband's last name)
The title character of Yann Martel's Life of Pi is named Piscine Molitor Patel (after a swimming pool in France that his uncle greatly admires). He shortens this to Pi Patel to escape the inevitable schoolyard taunts about "Piscine" sounding like "pissing."
Witch Week takes place in a world where witchcraft is a serious crime. Dulcinea Pilgrim is a girl who is named after the most famous witch in history, so it's small wonder she goes by "Nan" and has asked the headmistress of her school to keep her real name a secret. Of course, the headmistress forgets....
As L.A. Confidential says: "They stick you with a name like "Wendell", you look for an alias"
As if "Percy" wasn't silly enough, Lord John's lover/stepbrother in Lord John and the Brotherhood of the Blade isn't actually named Percival, but Perseverance.
In An Echo In The Bone, we meet brothers Herman and Vermin. This trope is speculated upon. A little more excusable given that they are in actuality the sisters Hermione and Ermintrude. And in A Breath Of Snow And Ashes, Roger christens a little girl, who the family name in his honor... Rogerina.
In Beyond the Magic Sphere, the main character's name is S.B. Fields. She refuses to tell anyone her real first name, which turns out to be Strawberry.
Doctrine of Labyrinths: Mild-may-your-suffering-be-at-the-hands-of-the-wicked. (His mother got religion.) He goes by Mildmay.
He also mentions knowing a prostitute originally named "Fly-from-fornication-and-blasphemy"; apparently, "Butterfly" went over better with her clients.
Corbie apparently isn't too happy about having been named "Gartrett," either.
One The No. 1 Ladies' Detective Agency novel mentions, in passing, a former classmate of Mma Makutsi's, whose parents saddled him with a name meaning "Look out, the police have arrived" in Setswana. Apparently, he tried very hard to get people to call him something else...
But names, like false allegations, stick, and he had gone through life with this unfortunate burden, reminded of it every time he had to fill out an official form; looking away so that the person examining the form could be given the opportunity to smile, which they all did.
In the Inspector Morse detective novels by Colin Dexter, Morse refuses to tell anyone his first name: the closest he comes is when he jokes that it's Inspector. Only in the penultimate book in the series is it revealed that his name is Endeavour.
Freakonomics examines the Real Life case study of NYPD officer Loser Lane and (to a lesser extent) his brother Winner. In regards to the former, "Although he never hid his name, people were uncomfortable using it. 'So I have a bunch of names,' he says today, 'from Jimmy to James to whatever they want to call you. But they rarely call you Loser.' Once in a while, he said, 'they throw a French twist on it: ‘Losier.’' To his cop friends he is known as Lou."
For added Irony, his brother Winner is notable for his impressive criminal record.
Lucifer C. Dye is the protagonist of The Fools in Town Are on Our Side by Ross Thomas. He would go by his middle name, but that's "Clarence."
Lupe dy Cazaril, the protagonist of The Curse of Chalion. The book has a fantasy setting where naming conventions aren't quite as we know them, but it's clear that "Lupe" is considered embarrassing In-Universe both because the protagonist doesn't use it unless he has to and because of the other characters' reactions when it does come out.
It means "wolf" and people used to make fun of him by howling like wolves.
In Keys to the Kingdom, the main character's best friends in his new school are called 'Leaf' and 'Branch'. Branch goes by 'Ed' instead.
In the YA vampire novel Team Human, the protagonist, Mel, tells us fairly early that her name is not short for Melanie and she's not going to tell us what it is short for, except that it was arrived at in the same spirit of experimentation that saw her brother named "Lancelot". Eventually her best friend gives her a Full Name Ultimatum and reveals it to be Mellifluous.
The protagonist from Anna Dressed in Blood is "Theseus Cassio Lowood"—a name that came from his father's love of Greek Mythology and his mother's love of Shakespeare. He insists people call him "Cas".
Theodor Fontane's Der Stechlin has two examples.
Dubslav von Stechlin, the main character, hates his first name because it is a name atypical of Brandenburg (the province of Prussia in which he lives) and typical of the neighbouring province of Pomerania.
Czech supporting character Nils Wrschowitz dislikes his first name partly because it is Northern Germanic and does not fit with his Slavic surname, but more importantly because his father named him after the 19th century Danish composer Nils Gade, whom he, as a very pronounced Wagnerian, has come to detest. Wrschowitz thus went to the effort of earning a doctorate in music so that he could print "Dr. Wrschowitz" on his calling-cards without the embarrassing first name. In the novel he is shown so touchy about his first name that people are advised not to mention anything or anybody Scandinavian in his presence as he will suspect you of obliquely reminding him of his Danish first name!
Melvin O'Neal, better known as Boots, from Gordon Korman's Macdonald Hall series.
The title character of Horatio Hornblower thinks his first name is pompous and ludicrous, and nicknames just make it worse. He uses simply "H." as a signature on personal correspondence.
Security Officer V. Stelmach from Deathstalker. Much speculation on behalf of Captain John Silence and Investigator Frost as to what the V Stands for. Turns out it stands for "Valiant," and he's somewhat ashamed that he hasn't lived up to his name, ending up only a Security Officer (rather like a political officer.) His similarly-named siblings have all made much greater strides towards living up to their names than he has.
It's a mild example, but Mr. London from Dinoverse gets annoyed when his students call him Bob. One of his students, upon discovering this, introduces him to people by saying they should call him that.
In The Year Of The Rat two of the characters' faithful cows are named no less than Disease and Death, because they took part in a half-ritual carnival involving the banishment of disease and death.
Angel: Lorne's full name is "Krevlornswath" in his native dimension, and even he isn't too fond of the shortened nickname. (He has green skin, which apparently made some people think of Lorne Greene from Bonanza).
iCarly: "Fredward" Benson. No wonder he goes by "Freddy".
Bill McNeal from NewsRadio was actually Evelyn William McNeal.
In one episode, Dan Fielding reveals that his real name is Reinhold (the creator of the show was Reinhold Weege.) Also, Fielding is actually his middle name; his real last name is Elmore. (The guy who tells everyone this in the episode also mentions that Dan played the accordion as a child. The guy really didn't like him.)
When Mac and Quon Li's daughter is born, she wants to name her after the storybook horse Flicka. They make it her middle name after Renee.
MacGyver always seemed embarrassed by his first name. Even former lovers only ever called him "MacGyver" (his grandfather called him "bud"). In one of the show's final episodes, his first name was revealed to be "Angus", which isn't really all that embarrassing. His embarrassment was probably based on the name originally scripted for him, which was "Stacey".
A more infamous example is Kramer on Seinfeld, who went several seasons before finally revealing his first name was Cosmo.
Also, Elaine dates a man who shared his name with serial killer, Joel Rifkin. After one too many embarrassing moments, he opts to change it. This leads to his breakup with Elaine as neither likes the other's choices for a new first name.
One episode of Kids Incorporated revealed that the character who had previously been known only as "The Kid" was embarrassed by his traditional African first name, Ras'san (Also the actor's first name; with two or three exceptions, every character on the show was The Danza). After a Very Special Episode taught him not to be ashamed of his heritage, everyone started calling him Ras'san. Right up to the end of the episode, after which it was never mentioned again. The guy left the show shortly afterwards.
Fox Mulder of The X-Files once told Scully that he made his parents call him Mulder. Interestingly, his middle name is the perfectly normal William. When his parents actually show up, though, they call him Fox — in fact pretty much everyone but Scully and the Lone Gunmen calls him Fox occasionally, and he never seems to have a problem with it.
Doctor McKay of Stargate Atlantis prefers to be addressed by his middle name, Rodney, because his first name is Meredith. Strangely his teammates don't know it; you'd expect that it would've been in his file, unless he had it legally changed. Good luck getting his sister to stop calling him that, though. An Alternate Reality McKay goes a step further and prefers to be called Rod. Then again alternate-Mckay is so damn awesome that maybe he goes by Meredith but his reputation precedes him enough for everyone to call him Rod, if you know what I mean. The McKay from the main timeline laments that he could never get anyone to call him "Rod."
Jesse's real first name on Full House was Hermes. He had it changed in Kindergarten.
In one episode of Married... with Children a male stripper who calls himself Raul admits to Al that his actual name is "Wilbur" when he returns Marcy's wedding ring (after she lost it while tipping him).
Inspector Morse's first name was not revealed for some time on the show, because he was embarrassed about it. Even lovers only called him "Morse". His first name was eventually revealed to be Endeavour. This practice has a history with him: one of his college friends from Oxford reveals that his nickname all through school was "Pagan", because he refused to give his Christian name.
And in the most recent season, Perry's full name is revealed to be Percival Ulysses Cox.
Uncle Phil from Mad About You thought he was dying and made the Buchmans promise to name their first son after him. He then revealed that his real first name was "Deuteronomy". He didn't hold them to their promise.
When his "dying" proved to be a false alarm, he revealed that his reasoning was sound if a little odd-Deuteronomy is such an unusual name that there would never be any of the confusion in child identification that so plagues the parents who were foolish enough to name their child "Joe".
Later they ended up naming their daughter Mabel, which it could be argued was a lateral move at best.
Due South's second Ray goes by his middle name; his name is actually Stanley Kowalski. His father "had a thing for Marlon Brando." The themed naming is exacerbated by an ex-wife named Stella.
In one episode of Life Support, the character Penne finally gets her revenge on her parents for giving her an awful name by sending them to Germany and getting them arrested under its strict child-naming legislation.
On the show Boy Meets World, Mr. Feeny reveals Cory's real name in the series finale.
Mr. Feeny: So, Mr. Matthews...
Cory: You think we've known each other long enough for you to call me Cory?
Mr. Feeny: I think we've known each other long enough for me to call you Cornelius.
Cory: Ssh! Mr. Feeny, come on! Not even Topanga knows that!
Another episode showed Feeny knowing the real name of professional wrestler Vader as Leslie (Although it's actually Leon in Real Life...) Amy Matthews also refers to him as Francis at one point, and he doesn't correct her.
Myron Lawrence Finkelstein fron Dharma and Greg, who usually goes by his middle name.
Adam Klaus in Jonathan Creek turns out to be using a stage name when his older sister Kitty arrives and refers to him exclusively as Chester, not a name with much credibility for a stage illusionist. (Kitty's Scottish accent throws suspicions on Adam's supposed American-ness as well.)
Andy (a girl) in Kyle XY, who lets everyone believe that her name is short for Andrea... it's actually short for Andromeda.
Lt. Provenza of The Closer has yet to reveal his first name. ("What's your first name?" "Lieutenant.")
An affadavit later shows his full name as "Louie M. Provenza."
Peter Falk gave the same answer when asked what Columbo's first name was. (A close-up of a badge seen in the second episode reveals it to be "Frank," though this wasn't clear until the show came out on DVD.)
In Friends Chandler's first name is considered embarrassing, though not so embarrassing that he doesn't use it. In one episode, they name one of Phoebe's brother's triplets after him:
Chandler: So uh, now that little Chandler turned out to be a girl, what are they gonna name her? Phoebe: They're gonna call her Chandler. Chandler: That's kind of a masculine name, don't you think? Phoebe: Works on you.
He also has an embarrassing last name:
Chandler: From now on, I have no first name. Joey: So - you're just Bing? Chandler: I have no name.
Not to mention his middle name. In short, the reason Chandler uses his first name is because it's the least embarrassing of his embarrassing names.
Ross: "Chandler Muriel Bing. Boy, your parents never even gave you a chance, did they?"
As per the quote at the top of the page, Ross and Rachel discuss the name of their as-of-yet unborn child. They agree beforehand that if the other person doesn't like the name, for whatever reason, they can "veto" the name. The argument goes on for long enough that eventually Phoebe pipes up with "Is it just me, or is 'Vito' starting to sound really good?"
On The Pretender, Dark Action Girl Miss Parker once threatened to shoot someone who was about to reveal her first name (hardly an empty threat). Her first name is unknown to this day, though it might be Angel.
Get Smart's Chief unwillingly reveals his first name, Thaddeus, under oath.
Also, Hymie the robot.
Hymie: My father's name was Hymie.
On Desperate Housewives, Mike and Susan name their son Maynard, after Mike's deceased grandfather. Susan's not happy about this and would have preferred Connor, afraid for what her poor son will have to suffer through in school. They compromise by calling him MJ (the 'J' standing for "James", the name of Mike's other grandfather).
The Vicar of Dibley Geraldine Granger's actual first name is revealed to be Boadecea, although this is inconsistent with the later revelation that her name is actually Geraldine Julie Andrews Dick Van Dyke Supercalifragilisticexpialidocious Chim Chiminey Chim Chiminey Chim Chim Cher-ee Granger.
Doc Cochran from Deadwood has the first name of Amos. He won't allow Merrick to print it in the vaccine announcement.
Cappie from GREEK. We know that his real first name is embarrassing for a long time before we learn what it actually is; eventually it's revealed that his full name is Captain John Paul Jones, thus making Captain his first name.
It's hard to tell if the real name of The Kid in the cowboy drama The Young Riders is embarrassing, but we can assume so, given the lengths he goes to to conceal it. After he whispers it to his friend, Teaspoon, who's officiating at his wedding to another of the Riders, Lou (Louise), Teaspoon looks perplexed and aghast before deciding just to go with Kid instead. Must have been bad!
Most of the characters from Are You Being Served?. Mr. Humphries's full name is "Wilberforce Clayborne Humphries". Mr. Harman's first name is "Beverly". Mr. Rumbold's first name is "Cuthbert". Mr. Lucas's first name is "Dick", which everyone else seems to find hysterical.
Firefly has fearless transport pilot Hoban. Hoban Washburne, that is, better known as "Wash". As he explains in the Serenity novelization, "Why would anyone call themselves Hoban?" The trope is notably averted by Jayne, who seems manly enough to pull off a name that sounds exactly like "Jane."
River: Jayne is a girl's name.
Jayne: Well, Jayne ain't a girl! If she starts in on that girl's name thing, I'll show her good and all I got man parts.
Simon: I'm trying to think of a way for you to be cruder. I just... It's not coming.
William Andrew Phillip Bodie, in The Professionals only ever went by the name "Bodie".
Punky Brewster's actual first name was Penelope. When the baliff in the debut story arc "Punky Gets A Home" announces it in a custody trial, she interrupts and insists on being announced as Punky.
From Teen Wolf, we don't actually know Stiles' real first name, but his lacrosse coach knows, and he's sure that it constitutes child abuse. ('Stiles' derives from his last name, Stilinski.)
Leonard Hofstadter from The Big Bang Theory once revealed he hates his first name, because the last syllable sounds like "nerd". To make things worse, his middle name is Leakey (after Louis Leakey, the famous anthropologist his father used to work with and has nothing to do with his history of bed-wetting).
Also, Sheldon's father apparently thought this about Sheldon.
Sheldon (re-telling a fight between his parents): "Stop yelling! You're making Sheldon cry!" - "I'll tell you what's making Sheldon cry: that I let you name him Sheldon!"
Spike in Flashpoint tries to avoid mentioning his real name if he can help it. Though Parker calls him by it when he gets cocky. It's Michelangelo.
In Boardwalk Empire, Enoch Thompson is called "Nucky" by everyone. In the first episode, when a woman says that she would like to name her child after him, he responds: "Enoch? You couldn't possibly be that cruel."
The Conners' old friend Ziggy on Roseanne was named Norbert. Even worse, his mom used to call him Norby.
Rizzoli & Isles: Det. Frost's first name is Barold. He normally goes by Barry.
Lab Rats: Principal Perry's first name is Terry, noting that she is female.
Magnum, P.I.: Rick Wright refuses to go by his real first name of Orville in the present day, as in the show's very first episode, Magnum has to threaten to reveal it to all of Hawaii to get Rick to cooperate with him. However, this was not always the case: flashbacks show that he answered to it without any problems while serving in Vietnam.
The 'Boy named Sue' from the song of the same name (written by Shel Silverstein and Covered Up by Johnny Cash). Of course, it's stated to have just made him into a badass, by making him get mad and fight everyone who called him that. And trying to kill his dad for naming him that.
In the folksong "Queer Bungle Rye" a sailor on shore leave met with a "damsel who skipped up and down," who pawned a child off on him under the pretense that it was bootleg liquor. He decided to christen the kid for some reason and gave it the song title as its first name.
Says the parson to Jack "That's a mighty queer name" "I'll be damned then" says Jack "at the queer way he came Smuggled up in a basket and sold on the sly And the name that he'll go by is Queer Bungle Rye-Raddy-Rye"
"Beat"'s true first name, "Daisukenojo", is so stupid, Neku wasn't even able to recognize it as a name when he first heard it (he thought 777 was cursing at Beat). What's especially painful for him is that it's just a more sucky version of the perfectly nice Japanese name "Daisuke". Had his parents just held back the last two kana, they would have saved him a lot of suffering.
Resident Manipulative Bastard Mr. Kitaniji counts as well. His first name is Megumi, which is a unisex name, but it's more typically used as a girl's name than as a boy's. The manga based upon the game goes further, implying that the childhood trauma of being teased for having a girl's name was one of the driving reason behind Kitaniji's ultimate goal.
Konishi: "But I thought you hated your name due to getting picked on about it sounding feminine?"
While it's never really touched on in either the games or the anime (probably because it wasn't an issue in the original Japanese), the male Magma Admin in Pokémon Ruby and Sapphire/Emerald has the decidedly feminine name "Tabitha". Similarly, the manga-only Aqua Admin (both Team Magma and Team Aqua have two male admins in the manga as opposed to the one in the games and anime) is named "Amber".
Otacon from Metal Gear Solid prefers to be addressed by his nickname, as he claims to dislike his actual name, "Hal". Somehow being named after the supercomputer from 2001: A Space Odyssey is more embarrassing than choosing the abbreviation for "Otaku Convention" as your nickname. Go figure.
Ironically, as soon as he becomes romantically attracted to Naomi Hunter in MGS4, he insists that she call him Hal. Which she does.
This becomes a huge Tear Jerker when she later dies and then afterwards post-humously leaves an encoded message in which she rather lovingly addresses him and says her final good-byes.
Pecker the monkaw from Jak and Daxter. He blames it on the fact that his mother was "very vindictive." You gotta wonder what Pecker did as a baby to make his mother name him that.
Hisui Hearts of Tales of Hearts, whose name is a girl's in Japanese and translates to the equally feminine "Jade". For some reason, Hisui himself is only called out on this passingly (in a sidequest where the revelation of his name tears down a badass bruiser image he'd built), and his predecessor Jade Curtiss in Tales of the Abyss not at all.
In Mass Effect 3, Jacob Taylor (assuming he survived the second game) is starting a family. Since you saved their lives, his girlfriend wants to name the baby after you. The problem is, your first name is player chosen, so the baby's name would end up as Shepard Taylor.
Jacob: I'm gonna talk her out of it. No offense.
Since Shepard's first name is player-chosen, and thus never spoken by any of the cast, the player could invoke this trope by giving their Shepard a truly embarrassing first name (and given the senses of humor of most gamers, it's probably happened more often than not.)
The player character in Freelancer usually goes by his last name Trent, as opposed to Edison. When he's introduced by his full name, he's quick to assert "It's just Trent."
In Ar tonelico, gunman Jack Hamilton decided to change his name after leaving the Teru Tribe. His real name? Harmonica.
In General Protection Fault, Trudy Trueheart's original name (She had it legally changed) is Moonbeam Gertrude Glowerhausen. (Hippie parents, y'see.) Anyone who learned this information would not live long enough to share it.
Roast Beef of Achewood was initially believed to be a girl when he was born, so his parents gave him the name of Cassandra. No wonder he became The Woobie.
From Gunnerkrigg Court, George Parley. It's embarrassing because she's a girl. Her father was a famous psychic who filled out the birth certificate before she was even born and got everything right except the gender, but they found the whole thing so funny that they didn't bother to change it.
In a Questionable Contentstrip, it is revealed Raven's first name is Blodwyn (her parents are Welsh), prompting amused reactions.
Richard from Looking for Group doesn't really hide his first name, but he still tries to confuse anyone who'd ask him by concealing it in a hurricane of nicknames. And of course, calling him Dick is just asking for being fwooshed.
Another Gaming Comic brings us "Joe Chaos", who's actual name is Irving. Not so bad. Then we have Dang, who's name eventually turns out to be Davros.
In Freakangels, KK's real name is Kolfinnia Kokokoho. Considering that Kolfinnia means winter in some Norse language and Kokokoho means Night Owl in Japanese, it's actually a well intended name. Of course, that dosen't stop KK from being extremely angry at anyone who calls her that.
Dr. Jeremiah Cook despises his first name, largely because his mother gave it to him and he doesn't like her very much.
Tessa's adoptive parents named her "Angel" (ironically); she had it changed when she was an angsty teenager.
Nathan from Electric Wonderland almost never goes by his real name for reasons the comic hasn't gone into much detail about. Most people call him, "NJ" (which he once said stood for "NinJa"). Aerynn calls him, "Nate," since she had discovered that to be his real name (his official bio also lists it as such), but he doesn't like being called that either.
In Educomix, Headmaster Poppington's first name is Dooby, and Spikeclops' first name is Spikeclopstopher.
V4 character Yelizaveta 'Bounce' Volkova, even though that's just the roughly corresponding Russian name for Elizabeth.
Tech Infantry has Andrea Treschi. It's a guy, but he's not too concerned about the name. On the other hand, there's Corporal Tess. Corporal Reichenspurger Tess, whose parents moved from a planet that followed the Asian custom of "family name first" to one that followed the Western custom of "family name last". The bureaucrat processing their paperwork screwed hers up, so she just has everyone call her by her "last" name.
The full name of Dr. Poque, the Big Bad of Mega64, is "Dr. Diarrhea Poque", as revealed at the end of episode 4 of season 2. Derek and Rocko find out much earlier on in the first season's second episode, though the name wasn't actually revealed then. Rocko does comment that it sounds like "some kind of butt disease," however.
In Yu-Gi-Oh! The Abridged Series, Yami Bakura's real name is Florence. He hates his name, and it's one reason why he's evil. In one of the Evil Council videos, he has a dream where some of his greatest wishes come true: among them, Florence being voted one of the manliest names ever. (This is the result of 'Ascended Fanon', as Bakura only mentioned that his parents wanted to call him 'Florence,' but the fans just latched onto it.)
In the episode "A Boy Named Sue", Mandark revealed that his hippy-dippy parents had named him Susan, much to his humiliation. The title of the episode is itself derived from the song written by Shel Silverstein and sung by Johnny Cash, about a boy who wants to kill his father for naming him Sue. It doesn't help that when Dexter meets Mandark for the first time, he has long hair and wears a girly dress, and Dexter calls him a little girl, despite Mandark's insistence that he is a boy. And when Dexter asks him what his name is and Mandark gives an affirmative answer, Dexter starts laughing at him. This, apparently, is what sets their rivalry into motion.
Recess: Tomboy Spinelli's first name is Ashley. This embarrasses her mainly because her sworn enemies are a gang of girls called "The Ashleys".
Other examples include Conrad "Connie" Mundy and Irwin Lawson. Like Spinelli, they also go by a Last Name Basis.
Evil, ambitious Mad Scientist and high school principal Cinnamon J. Scudworth in Clone High. Yes, he is the primary antagonist of the series, and, yah, he's male.
Drill Sergeant Nasty Emily Dickinson Jones in Duck Dodgers is a subversion; while Dodgers finds it funny, Emily himself insists that the 25th-and-a-half century no longer has gender-specific names and genuinely has no problem with his mother naming him after her favorite poet.
While it may have been a reasonable first name when the comic books were first written, the Animated Adaptation of Teen Titans pokes fun at the fact that Beast Boy has the first name... Garfield.
In Lilo & Stitch: The Series, it's revealed that Pleakly's first name is... Wendy. While he insists that it means "powerful warrior" on his planet, it still earns him lots of chuckles, and he refuses to go by it unless he has to.
In Phineas and Ferb's Cliptastic Countdown, we find Major Monogram's first name is Francis, much to the amusement of Dr. Doofenshmirtz (who isn't really one to talk, considering his first name is Heinz).
Cartoon or comic, Will Vandom of W.I.T.C.H. can never escape her real name. In the comics, it's "Wilhelmina" and in the first episode of the cartoon, it's revealed to be "Wilma". The comics made a recent example when Will flipped out over her relatives calling her baby brother (named William) "Will"... and then, they all started calling her "Wilhelmina" once they found out her real name, much to her displeasure.
Although he had always had it since his first appearance in the games, Adventures of Sonic the Hedgehog portrays Miles "Tails" Prower as "hating" his real name. In the episode in question, "Tails' New Home", not only does Sonic threaten to reveal that to everyone if he didn't bail, it also caused Sonic to realize he had been duped by Robotnik. note Sonic had thought they found Tails' missing parents and returned Tails to them. As he's remininsing, he realizes they called him "Tails", not "Miles".
Sonic also has this. Depending on source his real first name is either Maurice or Nikki. Following with this trope he prefers being called Sonic.
In his Archie Comics appearances, Sonic is embarrassingly referred to by his father as "Maurice". It is quickly revealed to be merely his middle name, implying that Sonic's actual birth name is unspeakably worse (Ogilvy).
While he never expressed any dislike for his real name, Shaggy from Scooby-Doo almost never went by his real name of Norville Rogers... for some incomprehensible reason.
In fact, most characters in this show should feel more embarrassed about their names than about their skin colors, but probably the only other character to whom this applies would be Skeeter (a.k.a. Mosquito) Valentine.
Rocky and Bullwinkle's "Fractured Fairy Tales" has a segment about a young girl named Tussinelda Wolfenpinkle, "but she had such lovely gold curls that everybody called her Goldilocks, which was probably just as well."
In "Son of Rumpelstiltskin", the titular character goes through the same motions as his father. The princess admits defeat, but demands to know what his name is before she hands her child over. He realizes he doesn't know, and spends the rest of the short trying to find out. When he discovers his name is "Rumpelstiltskin", he's too embarrassed to go back and claim his prize.
Twister from Rocket Power hates it when people call him by his first name, Maurice.
In season 5 of The Venture Bros., panicky bodyguard Sargeant Hatred reluctantly reveals that his first name is Courtney, thanks to an old-fashioned mother. Despite being an EX-villain, accidentally growing breasts, and being highly emotional, "Hatred" suits him far better.
In the film adaptation of Coraline, we have canon foreigner Wyborne "Wybie" Lovat.
In one episode of CatDog, where the characters prepare for the impending Apocalypse, a few of the Greasers take the opportunity to exchange emotional confessions. Cliff confesses that his name is short for "Clifford", and Lube follows suit by confessing that his real name is "Ignatius". After the latter confession, Cliff promptly kills the mood by laughing hysterically at Lube.
