Just For Fun / One Mario Limit

Go To
Don't lie; when you read that title, you thought of this Mario, right?

"It's a-me. Mario!"
Mario Auditore, Assassin's Creed II

In Real Life, the popularity of names goes up and down over time. One factor that affects this is the emergence of celebrities with a particular name; if there is some highly successful and well-loved pop star called Mario, then expect the number of babies named Mario to rise significantly.

In fiction, however, the effect can be reversed. If one character becomes sufficiently iconic, they can come to "own" their first or last name so that whenever a person hears that name, they immediately think of that character. A good way to determine if a character counts as this is to search for their name on Google or Wikipedia. If said character dominates the results, then it's highly probable that they hold the one name limit.

However, note that the ability of characters to cause this effect is to some extent a function of the existing popularity of their name; for a character to really achieve this distinction, their name must be sufficiently obscure enough to be distinctive but common enough that other writers would have used it. Indiana Jones provides a prime example of a highly iconic character who doesn't count — the name "Indiana" is so obscure that it would probably never have been used again even if Raiders of the Lost Ark was a total flop, while his surname is too common to have any attachments to one specific individual. Completely made-up names, like "Daenerys", would never have been used by other writers anyway and thus don't count either.


Compare One Steve Limit, which is the principle of having only one character with each name within a work to avoid confusion. Renamed to Avoid Association can happen if the creators want to avoid the One Mario Limit and name their character some other thing that hasn't been monopolized. Contrast Name's the Same, where by coincidence, two unrelated works have characters with the same name, and Baby Name Trend Starter, for when fictional characters or celebrities popularize a certain name. See Named Like My Name for when an ordinary name becomes famous by association with a particular celebrity.

NOTE: Do not list aversions unless it's relevant to the example. It leads to Trope Decay.

    Anime and Manga 
  • Naruto:
    • Naruto Uzumaki is by far the most famous bearer of his first name.
    • Sasuke Uchiha is easily the first thing that comes to mind when you hear the name "Sasuke", despite being one of the many characters named after the folkloric Sarutobi Sasuke. He's definitely the most famous of the references, though. His clan is indeed the dominant image of "Uchiha" in popular culture.
    • It's virtually impossible for another "Kakashi" to ever exist. Much less with a "Hatake" family name.
  • Lyrical Nanoha: It may be a real Japanese name, but you're not likely to see many Nanohas after the inception of this series.
  • JoJo's Bizarre Adventure:
    • Good luck finding another Jotaro or Josuke except for all of the protagonists named some variant thereof in the various series. The nickname Jojo is also nigh-exlusively tied to the Joestar family in the manga scene.
    • People are also likely to think of the Dio in this series if anyone else named Dio ever appears.
  • Fist of the North Star: There have been people actually named Kenshiro in real life who predate Fist Of The North Star, but there aren't a lot of other characters who use the name nowadays.
    • Kenshiro Tatara is a character from the manga Nurse Hitomi's Monster Infirmary, however the appearances of him as a young boy have plenty of little references to the other Kenshiro.
  • The name "Eren" has become so associated with the characters from Attack on Titan that you probably won't see any character in fiction with the same name for a while.
  • The uncommon Japanese name Tomie is probably forever going to be associated (to Japanese and especially Western audiences) with the alluring and antagonistic regenerating woman starring in the horror manga of the same name.
  • No Light Novel writer would name their character "Kirito" since Kirigaya Kazuto already owns this name.
  • You can't find an anime character with the name Nobi or Nobita anymore, because this name is unavoidably associated with a lazy, wimpy and immature kid from Doraemon.

    Comic Books 
  • Superman: "Lex". If you want a nickname for an Alexander character, then you better stick with "Alex", "Al", or "Xander" — unless it's a direct homage to him, as in Lex Luger. Clark as a first name also applies with the only possible exception being Clark Gable
  • X-Men:
    • "Xavier" as a surname is also unlikely to be used by another comic book character.
  • Spider-Man:
    • When you hear the surname "Parker", most can't help but think of Spidey.
    • The surname "Osborn" is completely tied to supervillain CEO Norman Osborn (a.k.a the Green Goblin) and his son Harry to a lesser extent. Just searching for "Osborn" on Google will bring up his profile over literally anyone else, be them real or fictional.
    • No lady will ever dare to address themselves as "MJ". That's Peter Parker's girlfriend. "Mary Jane" is even less likely since that's also slang for weed.
  • Thanks to Turma da Mônica (Monica's Gang), no Brazilian work can name their female characters "Monica" without associating them to a little girl with buckteeth and a stuffed rabbit doll.
    • Similarly, if any franchise happens to have the word "Turma" (Brazilian Portuguese for "Gang"), it's likely to sneak some "Turma da Mônica" content in search results. Just ask "Turma do Bairro" (the Brazilian translation for Codename: Kids Next Door), which is probably the reason why they added "KND" before the title.
  • "Averell" is an uncommon name in the Anglosphere and unheard of anywhere else... except in the world of Franco-Belgian Comics where it's cemented as the stupidest and nicest Dalton cousin from Lucky Luke.

    Comic Strips 
  • Calvin and Hobbes:
    • "Calvin" is usually associated with a six-year-old boy with a stuffed tiger.
    • Hobbes the stuffed tiger is probably as well known as the man he was named after (Thomas "Hobbes Was Right" Hobbes), if not more.
  • Peanuts:
    • "Charlie" and "Brown" can definitely be used individually, but not together unless it's for a bald boy with a yellow shirt with a black zigzag. (except Brazil, thanks to the band Charlie Brown Jr.) An obscure Batman villain known as Kite Man is named "Chuck Brown" and is a deliberate parody of Charlie Brown.
    • The name "Snoopy" is forever associated with the white beagle.
    • It's difficult to find other characters named "Linus", and if one is found at all, it's unlikely that they are as recognizable as Lucy's younger brother. Outside of fiction, only Linus Torvalds (creator of the Linux kernel) or Linus Sebastian can really contend with him.
  • Garfield. Either a fat cat, or the good old 20th president of the USA.
  • Dilbert is a disgruntled white-collar engineer and nothing else.

    Fan Works 
  • Good luck naming an Original Character Ebony without being accused of making a reference to My Immortal.
  • No fanfiction writer would name their character Mary Sue unless they are joking or are oblivious to the meaning of the name.

    Films — Animation 
  • Disney Animated Canon:
    • Thanks to The Little Mermaid, "Ariel" is probably going to forever remain associated with the eponymous lil' mermaid (she composes 99% of the results for searching the name on Google Images). Sebastian is synonymous with crabs nowadays too (with the only other noteworthy fictional character with the name being the titular character of Black Butler), while Ursula is forever associated with the villainous Sea Witch.
    • In Arabic-speaking countries, "Aladdin" (or, rather, its un-Anglicized form, Alā ad-Dīn, and its variants) seems to be largely unaffected by this trope. In English-speaking countries, however, it's almost always understood as a reference to the story (and, by extension, the Disney film).
    • Originally Iago was most associated with the character in Shakespeare's Othello, but the parrot has since taken control of the name.
    • The name "Mulan" has been thoroughly seized by Disney despite the character being based on a real person, and numerous other people and places sharing the name.
    • Good luck finding anyone named Bambi or Faline apart from the Young Prince and his mate. Bambi had been a popular name among strippers, but the closest you're probably going to come to the latter is a The Elder Scrolls V: Skyrim NPC whose name is pronounced identically but is spelled "Faleen".
    • There are few characters named "Aurora" anymore besides the Sleeping Beauty character. This was even enforced with My Little Pony: Friendship Is Magic. Starlight Glimmer was originally named "Aurora Glimmer", but Disney wrote an angry letter causing Hasbro to change her name.
    • The Lion King (1994): "Timon" is nowadays far more associated with meerkats than with historical figures or Shakespearean characters (Timon of Athens).
    • Encanto: Ever since "We Don't Talk About Bruno" became a Sleeper Hit, the semi-obscure name "Bruno" has been associated with Bruno Madrigal and the famous song about not talking about him.note  "Mirabel" also counts, even in Latin America since "Maribel" is more common.
  • An entire generation of people (specifically those born 1996 or later) only know the names "Melman" and "Kowalski" as talking zoo animals.

    Films — Live-Action 
  • Bond. James Bond, and no-one-else Bond. Amusingly, he was named after a real ornithologist, and the name was picked to be inconspicuous. And in real life, the name is pretty common, to the point a David Letterman Top Ten List had a James Bond saying advantages of the name.
  • "Krueger" has a last name has been forever associated with the villain of A Nightmare on Elm Street.
  • "Jason" is a very common name in real life, but horror fans will immediately think of Jason Voorhees. In fact, the name is so iconic that (as James Rolfe once pointed out) most people wouldn't even know who you were talking about if you bothered to give the full name, but will understand when you limit it to the first name. "Jason Voorhees? Who's that?" "You know, Jason." "OHHHH!! Jason! Right, hockey mask, machete." Try to find another slasher villain named Jason who didn't predate him and isn't a parody of him. (The last name Voorhees is probably even more so an example).
  • Mary Poppins: The surname Poppins is a practically perfect One Mario unless you count Chelsea Poppens, former college basketball player for the Iowa State Cyclones.
  • Eternal Sunshine of the Spotless Mind hangs a lampshade on this trope: when Clementine and Joel first meet, she asks him to not make any jokes about her name, but he still does by singing "Oh, my darling Clementine".
  • "Ferris" was never popular as a first name to begin with, but Ferris Bueller's Day Off effectively killed whatever usability it may once have had, both in film and in real life.note  Younger audiences however, would probably connect it to "Ferris wheel" rather than a name.

  • Sherlock Holmes, so much that the series Sherlock only need his first name in the title.
  • Vladimir Nabokov once said in an interview, "I am probably responsible for the odd fact that people don't seem to name their daughters Lolita any more."note 
  • Harry Potter: The name Hermione was once fairly obscure, but not unheard of. Before Harry Potter, it was most associated with a Shakespeare character, which was where J. K. Rowling got it from, or the comically grand actress Hermione Gingold. Now you probably can't hear the name without immediately thinking about Emma Watson. Draco and Ginny will likely also get this reaction.
  • Despite "Isabella" being a common girls' name in the US (at least partly due to The Red Stapler effect), its short form, "Bella," has become almost irrevocably tied to Bella Swan, the protagonist of the Twilight saga.
  • "Waldo" is an actual name but it is associated with Where's Waldo? in North America.
  • Try naming a character "Winnie" without being reminded of Winnie-the-Pooh, even though he is almost exclusively referred to as simply "Pooh" in conversations. One exception is Tuck Everlasting, where the main character is named Winnie (short for Winifred).
  • You will never find a character named "Samara" that is not a Stringy-Haired Ghost Girl. The same applies to her Japanese equivalent, "Sadako".

    Live-Action TV 
  • Star Trek: The Original Series: The surname Kirk is unlikely to be used in sci-fi again anytime soon. (Apart from joking references to Star Trek, obviously.)
  • There won't be much use of the surname House either.
  • The Muppets made Kermit synonymous with a talking frog. In real life, it was a real but uncommon name; Theodore Roosevelt's son, born in 1889, was named Kermit Roosevelt. Additionally, a man named Kermit Love was a long-time designer/builder with the Muppets, however, he only first met Jim Henson several years after Kermit the Frog had been created.
  • Grover, Elmo, Bert, and Ernie are residents of Sesame Street, and no other place in the universe.
  • Buffy the Vampire Slayer: The likelihood of TV characters having the name Buffy has gone down dramatically. Or at least ones that deal with vampires. Andi Mack features a Buffy among the regular cast, though they get the obligatory joke out of the way in the pilot - the character's young enough that she might very well be named for the fictional vampire slayer in-universe.
  • Seinfeld: The surnames "Seinfeld" and "Costanza" obviously can't be used elsewhere without comparisons to Jerry and George being made.
  • Chandler as a last name is perfectly acceptable. As a first name, it's still tied to Chandler Bing from Friends.
  • iCarly: Carly Shay has OML'd the name "Carly".
  • Bewitched: Darrin and Tabitha hold the One Mario Limit on their names to anyone over the age of 40.
  • "Sheldon" is a fairly popular name in both real life and fiction, but ever since The Big Bang Theory became a massive hit, it's almost impossible to not think of Sheldon Cooper upon hearing the name. Google certainly doesn't disagree based on the search results from the name "Sheldon" and it's especially telling that the show's prequel spin-off is simply titled Young Sheldon as if everyone would know exactly which Sheldon is being referred to.
  • For most 2000s kids, the name "Esteban" comes to mind a silly Hispanic bellhop.
  • The popularity of The Amanda Show and its star Amanda Bynes caused the name Amanda to become rarely used in fictional works.
  • Dawson isn't a first popular name, but still most people will think of the main character from Dawson's Creek when hearing the name.

  • All Elvises are direct shout outs to The King. The ones who are not are forced to use their full names.
    • Elvis Costello named himself in reference to Presley. And he sometimes released music under the pseudonym "The Imposters". His last name competes only with Lou.
    • Merengue singer Elvis Crespo (of "Suavemente" fame) was named after THE Elvis.
    • Folk singer Elvis Perkins was named after The Elvis by his father, actor Anthony Perkins.
    • A Swedish series of children's books by Maria Gripe features a young protagonist named Elvis by his Presley-loving mother. (Swedish children are NEVER named Elvis unless it's a tribute to The King.note ) After The King dies, his mom starts calling him Edwin or Edmund.
  • Don't expect to be hearing of any pop singers named Britney in the future. Britney Spears owns the name. The name "Britney" in general is this, as it's even a redirect to her page on Wikipedia ("Brittany" and "Brittney" haven't been hit as hard, but they're not immune).
  • Shakira isn't a particularly common Hispanic name, but it's not rare either. That being said, pretty much everyone bearing the name has had to deal with the inevitable "Hips Don't Lie" jokes.
  • When Madonna Ciccone's given name is that uncommon and that strongly associated with one person, many people assume "Madonna" must be a stage name. Her name is only rivaled by the Virgin Mary.
  • Reba McEntire is at the point in her career where, there are so few other Rebas anywhere, she named her own sitcom Reba and is usually listed as just "Reba" on the music charts. It's actually a very uncommon diminutive form of "Rebecca".
  • Though Miku is a real and common Japanese name, most people when hearing the name will immediately think of Hatsune Miku. The names Kaito and Meiko are also primarily associated with the Vocaloid characters.
  • Adele isn't that rare of a name, but now it is mostly associated with the British singer, especially after her international breakthrough in 2011. She's the reason that Adele Sandé goes by her middle name Emeli. In fact, her article on That Other Wiki is at simply "Adele."
  • The Russian singer Valeria. It's a stage name; her real first name is Alla. No, there cannot be another Alla on the Russian pop scene.
  • Country duo Maddie Marlow and Taylor Dye have the latter go by Tae because there's only room for one Taylor in country music. This, despite the fact that Ms. Swift has become a pure pop singer now. Likewise, Swift also has a monopoly on Taylors in pop music.
  • Good luck to any aspiring singer named Ariana. After Ariana Grande become popular on Victorious and especially upon her explosion in popularity as a singer, she practically took ownership of the name.
  • The name Miley is associated with the former Destiny Hope Cyrus and no one else.
  • Bruno isn't that rare of a European name, but nowadays you'll be hard-pressed to to find someone who won't immediately associate the name with Bruno Mars. Thanks to Sammartino (from whom Peter Gene Hernandez took his Stage Name), it becomes a two-Mario limit to wrestling fans like "Lana", "Kurt" and "Zayn".
    • Nowadays this name becomes a three-Mario limit, thanks to Encanto.
  • All Katherines who want to be known as "Katy" must go with "Katie" instead, thanks to Ms. Perrynote . No wonder Katy Tiz's career never went anywhere, or why UK singer Katy B’s popularity is almost non-existent stateside.
  • There is only one Mariah, Mariah Carey.
  • "Whitney" will always be most associated with Whitney Houston.
  • Elton seems safely secure nowadays.
  • Out of "respect" for the Queen of Soul, Aretha is fully off-limits.
  • Deliberately invoked by Tay Zonday. He said in an interview he picked the name because it was the first one he came up with that didn't show any other significant personages in a web search.
  • The Beatles: There are many people named John, Paul, and George, but there is only one Ringonote .
  • Korean Pop Music
    • There is only one Boa.
    • The K-pop companies can't have an idol with the name "Jungkook" anymore, unless you expect him to forever be associated with BTS.
    • Although Hyuna (pronounce hyun-ah) is a real and common Korean name, in K-pop industry, the name is unsurprisingly associated with Hyun A.
  • "Macarena" is not that rare Hispanic name. But people from non-hispanophone countries can't hear the name without immediately thinking about a song of the same name.

    Professional Wrestling 
  • Kevin Steen, known as Kevin Owens in WWE, takes sole ownership of both "Steen" and "Owens", although definitely not "Kevin".
  • It's highly unlikely there's ever going to be another Bray in professional wrestling, and certainly we won't be hearing "Wyatt" again either (outside of the name of the stable he led).
  • While "Foley" is a common last name in real life, it's practically unusable in the wrestling world if your name isn't Mick.
  • There is room for only one André in the professional wrestling industry.
  • Despite being a common name, there have not been very many notable Christians in the wrestling business besides the mononymous wrestler who may or may not use the last name Cage.
  • Shawn is another very common name that is almost exclusively associated in the wrestling world with one person. The S-E-A-N spelling is available though ("Shaun" is probably not, though). "Michaels" is probably OML'd as well.
  • Alberto is associated exclusively with Alberto Del Rio and nobody else. "Del Rio" too.
  • Enzo Amore has made sure that the name "Enzo" won't be used again, especially after the rape allegations against him surfaced note . "Amore" is this too, although to a much lesser extent than "Enzo".
  • Outside of India, Jinder Mahal has OML'd the name "Jinder".

  • When you mention the name "Kobe", you almost always get former basketball star Kobe Bryant instead of the Japanese city, the meat, or League of Legends caster Sam "Kobe" Hartman-Kenzler.
  • Stephen Curry is pretty much the only man who can use the nickname "Steph", as it's otherwise exclusively reserved as a shorthand for the female name Stephanie. Even the pronunciation of his name ("Steffen" instead of "Steven") qualifies.
  • "Cristiano" is the Portuguese form of the common first name "Christian". However, the name is almost exclusively associated with Portuguese footballer Cristiano Ronaldo.
  • Subverted with Tyson in boxing, which even led to a rename of Balrog of Street Fighter (originally known as "Mike Bison", he had his name swapped around with two other characters' in the Western release [the third name in the wheel being "Vega"] exactly to prevent potential legal troubles with Tyson)... and then someone named after Iron Mike, Tyson Fury, also became a heavyweight champion. (with everyone noting that the name-surname combo was both Awesome and basically forced him to be a fighter)
  • Usain is mostly associated with Usain Bolt, the Jamaican Olympic sprinter.
  • Lebron is not a common name, but most people associate it with King James, so much that the Cleveland Guardians (known as the Indians at the time) signed Luis Lebron to a minor league deal, jokes were made about Lebron returning to Cleveland.
  • Shaquille has become a more common in recent years, but it's so commonly associated with Mr. O'Neal, that the other Shaquilles were likely named after him.

    Stand-Up Comedy 
  • Ricky Gervais invokes this trope in one of his shows; there are not many "Adolfs" around these days, although there are many Robbies and Kylies.

  • Most of William Shakespeare's more famous characters are strictly off limits, and no one uses their names unless they intentionally mean to evoke those plays, Romeo being the worst offender.
  • Oedipus, with all its psychological infamy. Although in Brazil, Édipo is still used as a name.

  • "Barbara" is a commonplace name in fiction. One of its diminutive forms, "Barbie", is not. Almost every character called "Barbie" is a reference to the iconic doll-line. It's to the point where many don't realize that Barbie's name is actually "Barbara".

    Video Games 
  • The Trope Namer is, of course, Mario. Outside of the Mario series, you would be hard-pressed to find a single video game use of the name that isn't a Shout-Out or a licensed game using the name of a real person/character from another medium. Luigi isn't that common either.
    • Assassin's Creed II features Mario Auditore, but lampshades the fact with his introduction — "Don't you recognize me? It's-a me, Mario!"
    • As does Just Cause 3 when it introduces its character Mario Frigo. They try to be subtle about it; the line reading goes out of its way not to sound like the OG Mario's catchphrase.
      Mario: Rico? Is that you?
      Rico: Si, it's me. [short pause] Mario?
    • Looking up just "Mario" on The Other Wiki goes to the article for the Mario. Even his brother shares this distinction.
    • And now, Masashi Kishimoto, author of Naruto, has the audacity to name his one-shot manga about the Mafia Mario. He seems to be aware of the connection to the plumber but doesn't care, as in that issue's Author's Notes, he jokes about making a sequel called Luigi.
    • Mario's popularity is enough to have other Real Life Marios reference him through a "Super Mario" nickname. There's the NFL wide receiver Mario Manningham, Mario Lemieux of NHL fame (who, interestingly, got his own game on the Sega Genesis of all platforms, leading to some confusion about a Mario hockey game on a Sega system), footballers Mario Balotelli, Mario Gómez and Mario Suárez (only the former is Italian, though), the singer Mario (Dewar Barrett), former Prime Minister of Italy Mario Monti and Mario Draghi, President of the European Central Bank. To be fair, both Mario and Luiginote  are very common names in much of Europenote , the plumbers' fame having never really influenced their diffusion in any way.
It's same with onomatopoeia , for example, the onomatopoeic sound Thwomp which was used in comics at at the time, Is now the name of a recurring enemy of the Mario games, so whether searching the word on Google Images, Most of the results are images of those rock faces from the games, Some comics do use the sound effect in recent times, but not that often, It's also recurringly used in webcomics, sometimes, but not a lot.
  • Although the name had existed long before video games (let alone the franchise), Zelda will probably never be a prominent character in a video game ever again.
  • It's unlikely there will be any other characters called Kirby in gaming, despite it being a common name in real life. There are minor NPCs from Bully and Pokémon Diamond and Pearl named "Kirby", but the latter is in direct reference to the Kirby — he uses Cleffa, a Pokémon that resembles the pink sphere and is highly associated with stars.
  • Believe it or not, Ness was a rare given name meaning "from the headland" (as well as an anagram for the SNES console; EarthBound is funny like that). After EarthBound was released, though, it has become even rarer due to this character, even if he debuted in Smash Bros. for most.
  • Assassin's Creed II probably made the name "Ezio" unlikely to be used for a videogame character ever again.
  • The name "Lara" (a not-so-common variation of "Laura") is going to remain forever associated with the protagonist of Tomb Raider .
  • Grand Theft Auto IV killed the chances of another video game character called "Niko" (an uncommon variant of "Nicholas") existing.
  • Without question, the most famous fictional character named Heihachi is Heihachi Mishima from Tekken. The same can essentially be said for his son Kazuya, and for both the Mishima and Kazama last names. (Literature fans however tend to associate "Mishima" with Yukio Mishima rather than Heihachi or Kazuya.)
  • Final Fantasy:
    • Specifically with Final Fantasy VII, you likely won't get another major game character named "Cloud", let alone "Sephiroth".
    • The name Cid tends to be highly associated with the series, as every entry having a character with that name is a series tradition. The most popular of them is probably Cid Highwind from Final Fantasy VII. The character CID from Saints Row IV is a parody of the tradition. Despite this, one Final Fantasy title - Final Fantasy XII - did contain two characters named Cid (Dr. Cidolfus Demen Bunansa, the game's "official" Cid, and the more comic-relief orientated Al-Cid Margrace).
  • Fate/stay night has pretty much laid claim to all future uses of the surnames "Emiya", "Tohsaka", and "Matou".note  The masculine name "Illya" is also unlikely to be used as a Gender-Blender Name any time soon, as it's the short form of Illyasviel here — either the master of Berserker or the young magical girl version of her from another universe.
  • Thanks to the popularity of the Kunio-kun games, the name Kunio will forever be associated with hotblooded tough guy delinquents.
  • “Belmont” is only synonymous to the Belmont clan of vampire hunters from the Castlevania series.
  • The French name "Shantae" is so obscure the only thing that ever comes up in searches is a half-genie hero.
  • "Phoenix" is a unisex name that sounds nothing odd for girls. But if Phoenix is a boy, people may likely to associate him with Ace Attorney.

  • A fictional universe example: in the web comic Jack, it's said that the titular character gave such a... specially strong... impression (being a genocidal dictator surely helps), that no one has had that name since his death, because everyone grew sick of that name and no one likes the connotations. And it was implied that it had happened several centuries since, so...
  • dolan pls. Otherwise, he's a cardinal from New York City or a pair of vlogging twins named Ethan and Grayson.

    Western Animation 
  • There aren't many cartoon characters called Mickey.
  • The Simpsons:
    • No one will ever be able to call a character Homer or Bart now as they near-universally associated with those characters. "Homer" has even supplanted the ancient poet, Homer, in the public consciousness.
    • The surname "Simpson", despite being fairly common in real life, has this effect on non-anglophone countries, where it's pretty much exclusively associated with the cartoon family. This might be the case in the U.S. as well, with Family Guy hanging a lampshade in an episode featuring controversial American football player O. J. Simpson.
  • Phineas and Ferb: "Phineas" is such an old-fashioned name that most of the search results are for a certain triangle-headed kid. The only other fictional Phineas that comes close is a character in the School Study Media A Separate Peace.
    • Even more extreme in the case of Ferb.
      • Not to mention Baljeet, Buford, Perry, and to a lesser extent, Candace and Heinz.
  • Scooby-Doo: Velma and Daphne are now synonymous with two meddling kids. Shaggy is as well, when not talking about the singer who was popular for a few years in the late 90s and early 2000s.
  • Casper was actually one of the Three Wise Men (also spelled Gaspar). It's a really nice name, but if you name your child Casper, you better be prepared for constant comparisons to Casper the Friendly Ghost.
  • The name "Thomas" is very common in real life, but in children's television, it will forever be linked to the tank engine.
  • Courage the Cowardly Dog has done this with Eustace and Muriel, the former in particular due to its rarity as a given name nowadays.
  • South Park:
    • You can't have a character with the surname Cartman anymore, unless you want said character to forever be associated with a fat sociopathic kid. Also good luck trying to name a character Butters or Kenny (at least without references to being killed).
  • Looney Tunes: Elmer Fudd is who most people would think of when they hear the name "Elmer". Either him or Elmer's glue.
  • You will have a tough time finding a musician called Alvin that is not a cartoon chipmunk. The fact that a character shouts this name at least Once per Episode in pretty much every animated adaptation further cements this. Most British readers of a certain age will immediately think of Alvin Stardust, though of course he was really Shane Fenton.
  • It might sound unbelievable, but "Loud" is not that rare of a surname in the US. Too bad if you attempt to use that for a character though, since there's a whole cartoon family of at least 13 people currently owning it.
  • The name "Peppa" is going to remain forever associated with Peppa Pig.

Alternative Title(s): One Mario Rule, Only One Mario
