->''"It's true that it is always the winners that write history. But it is the losers that do the Transformers Wikipedia entry."''

The term used for obsessive fans of a particular activity that goes a bit too far onto the creepy side. Unlike {{fangirl}}s (which usually refers to women obsessed with characters and their relationships with either other characters or themselves to the exclusion of the rest of the elements of the canon), the term "fanboy" is usually reserved for antisocial people with a self-inflated ego over their knowledge and/or mastery of the topic in question, often parading it around and belittling those around him. They are to fandoms what StopHavingFunGuys are to tournament rules. Other times, the term is used to describe people who overzealously defend the perceived objective quality of the object of their obsession.

In Japanese, the term {{Otaku}} is synonymous with this, but implies an almost stalker-like attitude as well. The original (very pejorative) meaning got lost when it was adopted by English-language fans of {{Anime}}.

* Graham Specter from ''LightNovel/{{Baccano}}'' is the No. 1 Ladd Russo fanboy.
* In ''Anime/CodeGeass'', the two racist classmates who bully Suzaku - the FatAndSkinny ones - are credited as "Otaku 1 and 2". In their first appearance, they're taking pictures of the scene of a massacre, and lamenting that the military didn't use heavier weapons. Then they complain that Suzaku broke their cameras when he ''saved them''.
* [[LoonyFan Mikami]] of ''Anime/DeathNote'' is a Kira fanboy that would do just about anything for "God".
* Akito Tenkawa and Gai Daigouji of ''Anime/MartianSuccessorNadesico'' are such huge fans of ''Geikiganger 3'' that they even use attacks and battle cries from that show when fighting the Jovians.
* Bartolomeo from ''Manga/OnePiece'' is a ''massive'' fanboy of Luffy ever since Loguetown, an event that would eventually lead him to becoming a pirate. To the point that his ship is a nearly exact replica of the Going Merry, save that the figurehead is Luffy and the name is "Going Luffy-senpai".
* ''Anime/YuGiOh5Ds'':
** Rua is a fan of both Yusei and Jack, since both have held the title of 'King of Riding Duels'. Yusei also has huge fans in fellow inmate Yanagi and Team Taiyou's Yoshizo. [[spoiler: A more creepy example is Z-One, who is ''such'' a Yusei fanboy that he surgically altered himself to look ''exactly like Yusei''.]]
** A young boy called Toby is a big Aki fanboy, to the point that he joined the Arcadia Movement due to his admiration of her. [[spoiler: This ends up [[KillTheCutie horribly]] for him.]]

[[folder:Comic Books]]
* ComicBook/{{Deadpool}} is such a huge fan of ComicBook/CaptainAmerica and [[ComicBook/TheMightyThor Thor]] that he doesn't mind the latter beating him up.
* The ''ComicBook/XMen'' villain Sauron is obviously a ''Literature/TheLordOfTheRings'' fanboy, as he named himself after that trilogy's BigBad.
* [[{{Adorkable}} Ironfist]] is an ''enormous'' nerd for [[BadassCrew the Wreckers]], including writing tons of data files on them, buying memorabilia, and knowing all sorts of minutae that would only interest hardcore fans of the team (the Transformers Wiki even notes "Oh dear lord, he's ''us!''"). He [[AscendedFanboy ascends]] to join the team he idolizes in ''ComicBook/TheTransformersLastStandOfTheWreckers''. Flashbacks reveal he has ''always'' been like this--before the Wreckers came into being, he geeked out over the Primal Vanguard, an early Cybertronian peacekeeping detachment.

[[folder:Fan Works]]
* Hiro (of ''Disney/BigHero6'') is a huge [[ComicBook/IronMan Tony Stark]] fan in ''[[http://archiveofourown.org/works/3212093/chapters/8076183 Magnets for Trouble]]''; after meeting him unexpectedly, Hiro nearly starts hyperventilating.

[[folder:Films -- Animation]]
* In ''WesternAnimation/TheBookOfLife'', Goth Kid becomes quickly enamored with both La Muerte and Xibalba. [[spoiler:He ''faints'' when La Muerte waves goodbye to him and the others]].
* In ''Disney/BigHero6'', Hiro Hamada is shown to be a mild fanboy of Professor Callaghan, complete with a small gush moment when he meets him.
* Syndrome of ''WesternAnimation/TheIncredibles'' used to be this for Mr. Incredible. He didn't take rejection well.

[[folder:Films -- Live-Action]]
* ''Film/TheAvengers2012'':
** Agent Phil Coulson has vintage Captain America trading cards. Completing the set took him years. Also, [[ThatCameOutWrong he watched Rogers while he was sleeping]].... we-we mean, he was... he was present, while [[HumanPopsicle Rogers was unconscious...from the... ice]].
** Tony Stark is a fan of Bruce Banner for the latter's work on anti-electron collisions, also [[TheLastOfTheseIsNotLikeTheOthers he claims that he is a huge fan of the way]] Bruce [[UnstoppableRage loses control and]] [[TheHulk turns into an enormous green rage monster]].
--> '''Bruce''': [[DeadpanSnarker "....thanks."]]
* Creator/PattonOswalt's character Paul in ''Film/BigFan''. Unlike most fanboys, Paul does not obsesses over Sci Fi, Fantasy, Comics, Anime, or Video Games, he is a football fan. He was beaten up by his sport hero, and does not press charges in order to support his favorite team The Giants.
* The film ''Film/{{Fanboys}}''. Duh.
* ''Film/FreeEnterprise'' is a whole film devoted to this. It follows two fanboys who fulfill the nerd dream of striking up a friendship with Creator/WilliamShatner, only to find out he's as much of a loser (in-universe, mind you) as they are.
* Kylo Ren is completely obsessed with Darth Vader and fulfilling his legacy in ''Film/TheForceAwakens''. He keeps Vader's melted mask in his room like a shrine and talks to it like someone might pray, and Rey finds out that his greatest fear is not being as strong as Vader was.
* [[AffectionateParody Affectionately parodied]] in ''Film/GalaxyQuest'' with the character Brandon, played by Justin Long.
* Jimmie "The Rocketman" Zara is this to Troy Bolton in ''Film/HighSchoolMusical 3.''
* Walt the Fanboy in Film/TheViewAskewniverse movies (''Film/{{Mallrats}}'', ''Film/ChasingAmy'', ''Film/JayAndSilentBobStrikeBack'').
* In ''Film/KayfabeAFakeRealMovieAboutAFakeRealSport'', Cam Cunningham is obsessed with the wrestling business and with Randy Tyler, and yearns to be a wrestler himself.

* ''Literature/HarryPotter'': Colin Creevey is Harry Potter's very eager fanboy.

[[folder:Live-Action TV]]
* ''Series/BuffyTheVampireSlayer'': Mr Trick is one of ''ComicStrip/{{Marmaduke}}''. "Nobody can tell Marmaduke what to do. That's my kinda dog."
* During the "iStart A Fan War" episode of ''Series/ICarly'', there is one fanboy for the Sam/Freddie 'Seddie' {{Shipping}} couple who is a textbook version of this. He stands up and shouts "SEDDIE!" over and over. For those with knowledge of the fandom, he's obviously based on one specific BigNameFan who became well known for those antics on the creators blog and websites.
* Fanbot from ''Series/VRTroopers''. Although mostly comic relief with his Hollywood fanboy personality and proved to be a bit clumsy, he was actually [[NotSoHarmlessVillain the most powerful monster of the week they faced all season]]. Before fighting the Troopers, he was assigned to destroy a traitorous ally's super powerful robot, which he did [[CurbStompBattle fairly easily]]. JB's normal finishing move (the laser lance) was so ineffective that be it impalement, slashing, you name it, it only tickled to the point where he made a joke about it. JB actually had to hit him with the techno-bazooka to defeat him, [[NighInvulnerable a weapon used against multiple aircraft]] (but repowered his laser lance and attacked the already defeated robot for some reason). His personality was lampshaded when JB said during the battle "sorry, no autographs" and "there's nothing worse than an angry fan". He actually wasn't a fanboy by designed but a giant industrial fan (he killed the other robot by sucking his parts through his blades), so his name was a [[IncrediblyLamePun pun on fan]].
* The character of "Whizzkid" in the ''Series/DoctorWho'' story "[[{{Recap/DoctorWhoS25E4TheGreatestShowintheGalaxy}} The Greatest Show in the Galaxy]]" is widely-seen as a demonstration of how the show's creators at the time regarded fanboys. Especially his rapid and horrible death.

[[folder:Pro Wrestling]]
* Wrestling/StevieRichards early days in Wrestling/{{ECW}} saw him wrestle under the ring names Stevie The Body, Stevie Flamingo and Stevie Polo. He was a fan boy of Wrestling/{{Raven}}.
* Dragon Shynron, ACH and Mr. 450 are fan boys of ''Manga/DragonBall'', the former two even [[TagTeam team]] together as "FusionDance". Unlike most depictions of fan boys, they're also ''awesome''.

* Solek from ''Toys/{{Bionicle}}'' is a Kopaka-fanboy, to the point that he changed his color to white to look more like his idol. When they meet, Solek's overjoyed and starts asking about his legendary adventures, which Kopaka doesn't remember due to amnesia.

[[folder:Video Games]]
* The Adoring Fan of ''VideoGame/TheElderScrollsIVOblivion'' was a character who would appear after you became the Arena Grand Champion and follow you everywhere. His obsessive devotion to your character has led many people to try to kill him by any means necessary, and his tendency to respawn only made him more annoying.
* Conrad Verner, Shepard's [[ThisLoserIsYou biggest fan]] in ''Franchise/MassEffect''.
* Elder Xelpud in ''VideoGame/LaMulana'' is an UsefulNotes/{{MSX}} fanboy, and a few of his quotes have him [[TakeThat railing against the]] [[UsefulNotes/NintendoEntertainmentSystem NES]].
* Dr. Hal Emmerich, in the ''Franchise/MetalGear'' universe, is a brilliant scientist...who self-identifies as an Otaku. His code name, Otacon, is derived from Otakon, the Otaku Convention. (This was done with the con's permission; in return, their program each year lists "Dr. Hal Emmerich" as their "Scientific Adviser.")
* The [[ShowWithinAShow fictional TV show]] ''Steel Samurai'' in the ''VisualNovel/PhoenixWrightAceAttorney'' games has a few of these, as well as its spin-offs like the Nickle Samurai and the Pink Princess and rival show Jammin' Ninja. Maya is a huge fan of all of these and is always dragging Phoenix into the mix, and in the third case of the first game, we meet Cody Hackins, a kid who obsesses over the show so much that he photographs all of the Steel Samurai's finishing moves and refuses to believe that the Steel Samurai would lose a fight/get murdered. Cody's Japanese name, Kyuuta Ootaki, is a similar to that of {{Otaku}}.
** The biggest Steel Samurai fanboy in the series, however, is Miles Edgeworth. It's subtle enough in the other games, but it's TurnedUpToEleven in Edgeworth's own spin-off game. At one point he even tells someone they're not fit to call themselves a true fan of the Steel Samurai because [[spoiler: they claim to have gone to the bathroom during the climactic scene of the play.]]
*** And oh, does the {{hilarity ensue|s}} when Edgeworth finds out [[spoiler: the guy under the Steel Samurai costume who he's been fanboying all evening is Larry Butz.]]
* Francis in ''VideoGame/SuperPaperMario''.
* Eusine from ''VideoGame/PokemonGoldAndSilver'' really, really likes Suicune.
* Hifumi Yamada from ''Franchise/DanganRonpa'' is literally known as "Super Duper High School Otaku."

[[folder:Web Comics]]
* In ''Webcomic/{{Skins}}'' Jordan and Rabbit are huge geeks despite being hardened supernatural soldiers. Jordan is enough of nerd to cosplay as [[spoiler: Commander Shepard]] and Rabbit attends the costume party as [[spoiler:Dante]] and [[http://lj-phillips.deviantart.com/art/Under-My-Skin-4-Say-My-Name-374116884 refuses to even answer Jordan unless she addresses him as such! ]]
* ''Webcomic/{{Sinfest}}'':
** Seymour to God
** Lil' E to Satan

* In ''Webcomic/TheSpecialists'', [[http://thespecialistscomic.com/page-81/ Max to Captain Victory]]. Poor Max.
* In ''Webcomic/ElGoonishShive'', Nanase and Ellen [[http://www.egscomics.com/?date=2013-05-31 gain one]] [[http://www.egscomics.com/?date=2013-06-03 in Elijah]] due to [[http://www.egscomics.com/index.php?arcid=107 their mystery solving adventures.]]

[[folder:Web Original]]
* Captain Hammer from ''WebVideo/DoctorHorriblesSingAlongBlog'' has a fan trio composed of two {{fangirl}}s and a CampGay fanboy. After his humiliating defeat, they abandon him in favor of Dr. Horrible.
* Website/ThatGuyWithTheGlasses has Douchey [=McNitpick=], a repulsive kid who [[BasementDweller lives in his mother's basement]] and represents FanDumb to the WebVideo/TheNostalgiaCritic, [[WebVideo/AtopTheFourthWall Linkara]] and WebVideo/TheNostalgiaChick.
* All four main members of [[WebVideo/BrainScratchCommentaries The Brain Scratch Crew]] are fanboys of the [[Franchise/SonicTheHedgehog Sonic The Hedgehog series]].
* In ''WebVideo/VaguelyRecallingJoJo'', Kakyoin is a big fan of ''WesternAnimation/ThePowerpuffGirls'' and he's a huge enthusiast of portable games, as he cried when his DS and PSP were broken.

* ''WebVideo/SwordArtOnlineAbridged'' tweaks Kuradeel's character to reveal that [[spoiler:he is this to Laughing Coffin, and he wants to kill Kirito for "tainting their image".]]

[[folder:Western Animation]]
* On ''WesternAnimation/AlmostNakedAnimals'', Howie is so obsessed with a stuntman named Dirk Danger that he hangs out in Dirk Danger's cave and tries to coax him out of retirement.
* In ''WesternAnimation/{{Animaniacs}}'', [[http://www.youtube.com/watch?v=hgd5S-X-_dQ The Please Please Please Get a Life Foundation]] was created to help these people.
* [[FanNickname Fan-named]] Frothy on ''WesternAnimation/AvatarTheLastAirbender'' counts, although personality-wise he's almost more of a male fangirl.
* One episode of ''WesternAnimation/TheClevelandShow'' has Cleveland get into an Administrivia/EditWar with someone over the grams of fat content of a microwave snack. The war escalates when the other fan in question slanders Cleveland's image. When Cleveland finally meets the person slandering him, the person is revealed to be an obese pre-teen who admits to eating the snack five times a day because he loves the snack and is a true fan.
* ''WesternAnimation/FanboyAndChumChum'': The title characters were clearly meant to be this, but aside from wearing superhero costumes and occasionally being seen reading comic books, they don't exhibit typical fanboy behavior. Oz, their acquaintance and the owner of the local comic book shop, is a textbook example.
* [[ExactlyWhatItSaysOnTheTin "Fanboy"]] (pictured) from ''WesternAnimation/{{Freakazoid}}''.
* Melllvar from ''WesternAnimation/{{Futurama}}'' is a ''Series/StarTrekTheOriginalSeries'' fan[[strike: boy]]-energy-cloud-thing. To the point of hosting his own ''Franchise/StarTrek'' convention, complete with MarySue fanfic, and being pissed that Fry's a bigger fanboy than him.
* On ''WesternAnimation/GoldieAndBear'', Bear and Goldie are this respectively to Prince Charming. He doesn't really care and is willing to put up with it so long as it gets him a day of fun away from his boring princely duties.
* Irving, in ''WesternAnimation/PhineasAndFerb''. A nerdy local kid who was introduced in "Hide and Seek" as an obsessive fan of Phineas and Ferb and their ambitious antics. He tags along with their daily projects on occasion in later episodes.
-->'''Irving:''' I jumped in the car when your mom stopped for gas: I'm just happy to be here!
* ''WesternAnimation/TheSimpsons'': Comic Book Guy: While often being used for TakeThat gags, [[Series/WonderWoman Lynda Carter]] has a restraining order on him and he was almost married with a [[Franchise/StarTrek Klingon]] priest. Of the three ''Star'' franchises, ''[[Franchise/StarTrek Trek]]'', ''[[Franchise/StarWars Wars]]'', and ''[[Franchise/StargateVerse Gate]]'', Richard Dean Anderson's is his third favorite.
* Darth on ''WesternAnimation/{{Sixteen}}'' is a ''Franchise/StarWars'' fanboy. He wears a cape and a Darth Vader helmet, carries a red lightsaber, and is part of the Jedi Knights club. Oddly, one of the "clones" (mean girls) is also in the Jedi Knights club, AnAesop about how you shouldn't label people.
* Control Freak of ''WesternAnimation/TeenTitans''. Aqualad even calls him out on it.
