->''" I'' should ''want to cook ''[Mr. Belvedere]'' a simple meal. But I'' shouldn't ''want to [[SuspiciouslySpecificDenial cut into him, to tear the flesh, to wear the flesh, to be born unto new worlds where his flesh becomes my key]]."''
-->-- '''Deranged fan of ''Series/MrBelvedere''''', ''Series/SaturdayNightLive''

A nut who follows the main characters everywhere out of obsessive admiration, either causing trouble or just creeping them out. Extreme loony fans may go to great lengths and evil deeds to [[PsychoSupporter "help" the hero they idolize]]. They take their eventual rejection very personally. Occasionally this character will really go off the deep end and attempt to ''replace'' their hero.

This can also overlap with the StrawFan, TheCollector, the {{Yandere}}, the PoisonousFriend, and/or the StalkerWithACrush.

Compare ActorRoleConfusion, CannotTellFictionFromReality. Contrast with AscendedFanboy.

Sad (and a little scary) to say, this is ''very'' much TruthInTelevision.

!!Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* A number of anime series feature cult-of-personality fan clubs in high school settings (ie. Fruits Basket, Love Complex). Usually played for laughs rather than played straight.
* Played for laughs in ''DarkerThanBlack'' (and maybe a little [[ShipSinking torpedo aimed at shippers]]). [[SassySecretary Kiko]] is portrayed as slightly crazy anyway, but her crush on "Li" tops all other quirks. She almost jumps on him with {{squee}}, loudly insults her "rival" Kirihara, and generally attracts unnecessary attention... which is somewhat disconcerting for her hero, as "Li" is the facade identity of a lad who ''earned'' his nickname "Black {{Shinigami}}".
** Hei has another one in the {{OVA}}, Mayu, with the added bonus that she manages to connect his identities ([[BunnyEarsLawyer thereby beating out the entire police force]]) and starts [[StalkerWithACrush actively stalking him]].
* Gokudera from ''Manga/KatekyoHitmanReborn''. He frequently goes off to beat people up for Tsuna's sake, and [[StalkerWithACrush follows Tsuna around]] trying desperately to be his "Right Hand Man." Although the funny thing is that his attempt to replace the hero was actually his initial feeling, and that it's ''after'' being [[DefeatMeansFriendship defeated]] by Tsuna that he becomes his LoonyFan.
* [[spoiler: Kasaya's girlfriend Eri]] from ''{{Zetsuai 1989}}'' goes so over the edge that [[spoiler: she tries to stab her idol Kouji because he's about to go into retirement]].
* Arguably the basis of the 1998 anime film ''Anime/PerfectBlue'' (unarguably, a LoonyFan does at least ''appear'' in the anime).
* [[spoiler:[[StalkerWithACrush Toto Sakigami]]]] of ''DeadmanWonderland'' is apparently this toward [[spoiler:the Wretched Egg]].
* Lecto from ''MagicalXMiracle'' has a series-long obsession with Yue (as well as great admiration for Merleawe for being so close to him), to the point where things get... [[HoYay awkward]]. However, this turns out well for both of them; Lecto eventually becomes an in-series PromotedFanboy as one of Yue's top aides, and his nerdy personality quirks and stalker-like obsession settle down after Yue puts him through three years of {{Workaholic}} boot camp.
* Hayashi Rintaro, also known as Rin-rin, is the local florist on ''Manga/ShirokumaCafe''. He's also a scarily obsessive fan for pandas to the point that Panda, the resident AttentionWhore, can't stand him and all the attention that Rin-rin gives him.
* In ''Anime/YuGiOh5Ds'', the BigBad [[spoiler:[=ZONE=]]] is revealed to be a Loony Fan of [[spoiler:Yusei]]. He admired [[spoiler:Yusei]] so much that he [[spoiler:altered his own face to look like Yusei as part of his plan to emulate Yusei as much as possible in the hopes that some of Yusei's luck would rub off on him to help his plan.]]
* Being a deconstruction of the FightingSeries PlayedForLaughs, MutekiKanbanMusume: Deconstructs this trope with Akihiko, who despite being abused at his childhood , has become an adult NiceGuy who is everyone’s ButtMonkey. Akihiko deeply desires to be the like the Red Ranger (from the {{Sentai}} ShowWithinAShow Star Rangers) because he is always recognized for his efforts with a HundredPercentHeroismRating. Akihiko is so found of the Red Ranger that he copies his CatchPhrase ''I’ll pay them back several times over'' and uses it in situations that doesn’t even make sense:
-->'''Akihiko:''' ''[[CannotTellFictionFromReality Just leave it to Star Ranger!]]''
-->'''Wakana:''' (Very confused) ''Star Ranger?''
-->'''Akihiko:''' ''That Toshiyuki, I’ll bring him back several times over.''
-->'''Wakana:''' ''No, just once is enough.''
* ''LightNovel/{{Baccano}}'': [[TalkativeLoon Graham Spectre]] to the resident PsychoForHire, Ladd Russo. [[AxCrazy Ladd]] being [[BlueAndOrangeMorality Ladd]], he doesn't mind.
* [[MadLove Misa Amane]] of ''Manga/DeathNote'' is this to VillainProtagonist [[SerialKiller Light]] [[MagnificentBastard Yagami]], albeit a particularly dark, homicidal example; after he winds up killing the guy who killed her parents, she's more than glad to murder his enemies or endure ColdBloodedTorture to protect his identity. She's also glad to [[TheGlomp flying tackle him at unexpected intervals]], much to his dismay. A crucial part of her own backstory involves a narrow escape from a LoonyFan - the parallel is as lost on Misa as warnings about moral decay are on Light.
* The fanbase for the titular ''DetroitMetalCity'' is made up mostly of loud, vulgar and belligerent fans who can't tell that frontman Krauser II and his insane, over-the-top antics is just a persona, and often show up around Krauser when he's out of makeup and unrecognizable to cause trouble.
[[/folder]]

[[folder:Comic Books]]
* Jimmy "Mmy" from JhonenVasquez's ''Comicbook/JohnnyTheHomicidalManiac'', although he is considerably less insane than [[AxCrazy Nny]].
* The extradimensional imp Bat-Mite in the wackier Franchise/{{Batman}} comics.
* Jenny in ''Comicbook/ThePunisherMAX'' comes across as this. After seeing Frank shot by the women she is targeting she saves him and takes him to her apartment. The scenes between them invoke {{Misery}}, and Frank feels a little like her prisoner, but Jenny does nothing to stop him and the reason he can't leave is his gunshot injuries, and he patiently listens as she describes what was done to her, and sympathy for what was done to him. Jenny then has two requests: his shirt and jacket so she can become The Punisher and kill the women who hurt her, and that he stay until she finishes it. Frank feels more and more like he's trapped, and that Jenny would stop him even if he could leave, before passing out and ending up handcuffed so Jenny can show him how to torture criminals.
* In ''Comicbook/GreenLanternCorps'', Iolande's brother Ragnar was so obsessed with the Corps he murdered every potential Lantern candidate in their sector so he would end up the best candidate for the position, including his brother Stentar and Soranik Natu's partner Myrrt. When Ragnar was finally exposed, captured, and set for execution, Soranik purposefully chose to reveal that Iolande would be the new Green Lantern of Sector 1417 right before Ragnar would be beheaded. To add to this KickTheSonOfABitch moment, Ragnar made an empty admission of guilt and repentance to show he "wasn't afraid" before his execution, thinking he ''still'' had a chance to be a Lantern. The look on his face when Soranik takes out the ring, then gives it to his sister, is satisfying.
[[/folder]]

[[folder:Film]]
* In ''TheIncredibles'', the villain Syndrome was once a young LoonyFan who wanted to be Mr. Incredible's sidekick, and his rejection was one of the factors that led him to become a villain, not an AscendedFanboy, as he so desperately wanted, but a GenreSavvy bad guy.
* RobertDeNiro's roles in ''[[ExactlyWhatItSaysOnTheTin The Fan]]'' and ''The King of Comedy'' fit this trope as well.
** In fact, ''The King Of Comedy'' has two loony fans who are obsessed with the same in-universe celebrity, [=DeNiro=] just has the lead role: Rupert Pupkin mainly seems obsessed with Jerry Langford because he wants to be famous himself, while Masha (Sandra Bernhardt) is more of a traditional StalkerWithACrush type, eventually having a CaptiveDate with Langford.
* The Kid in the ''[[Franchise/TheMatrix Matrix]]'' sequels is portrayed as a mild example of this.
* From the ''Franchise/{{Halloween}}'' series:
** The radio show callers in ''Film/HalloweenTheCurseOfMichaelMyers''.
** Harold in ''Film/HalloweenResurrection''.
** Chett in ''Film/HalloweenII2009'' (2009).
* In ''Film/BladesOfGlory'', Jimmy having one of these is kind of what causes the plot to kick off, but in a surprisingly non-scary way in spite of some of the creepy things that the LoonyFan says to him. This particular fan of his is so obsessed with the idea of having Jimmy back on the rink and is so much the type to think about these things a lot that he manages to find a loophole in the Figure Skating Championships rulebook that Jimmy then exploits.
* The eponymous teddy bear of ''Film/{{Ted}}'' used to be a celebrity thanks to being a {{Living Toy|s}}. While he no longer has that status, he still has an obsessive fan named Donny, who wanted his own magical teddy bear when he was a kid. When his father denied him one, he vowed never to deny any similar request for his own son. Donny and his son Robert first attempt to buy Ted off from John, but when that didn't work out, they resort to kidnapping him.
* ''Film/BobRoberts'' has a collection of {{Loony Fan}}s (including an early Jack Black) who start off as kooky religious fanatics and then quickly upgrade to outright malicious when they assault a group of protestors outside one of his concerts. [[spoiler: One of them is implied to have shot and killed Bugs Raplin, who was exposing some of Roberts' dirty secrets until Roberts faked an assassination attempt (and the parapeligia that followed) and pinned the blame on him, and when one of the fans camped outside his house catched him walking around by a window, he immediately assumes it was a miracle instead suspecting any fowl play.]]
* Played for laughs in ''Film/{{Bombshell}}'', in which glamorous Hollywood star Lola Burns has a Loony Fan who keeps popping up and telling her she has to come home to take care of their babies.
[[/folder]]

[[folder:Literature]]
* Taken to [[DarkerAndEdgier dark extremes]] with Annie Wilkes of Creator/StephenKing's ''{{Misery}}''. Though she's more like an AxCrazy fan.
* ''Literature/HarryPotter'': Colin Creevey.
* Literature/TheCulture: A less technologically advanced civ, the GFCF, imitate the Culture and think that they are the best people in the galaxy. They don't do it very well, and although the Culture consider them vague allies, they don't take them seriously. This could be a mistake...
* OlderThanSteam: ''Literature/DonQuixote'': Sanson Carrásco presents himself as the number one fan of Don Quixote and discusses various [[SeriesContinuityError continuity errors]] with him and Sancho. However, his real goal is to help the poor, mad fool regain his sanity by following in his third quest. HilarityEnsues.
[[/folder]]

[[folder:Live Action TV]]
* Played for laughs in an episode of ''{{Friends}}'', where Brooke Shields portrayed a LoonyFan stalking Joey, convinced [[YourSecretsSafeWithMeSuperman he was really the character]] he played in a soap opera (they got rid of her by convincing her that Joey was actually the EvilTwin instead).
** There was also the [[HappyDays Fonzie]]-obsessed doctor who delivered the triplets.
* In ''Series/{{Monk}}'', SarahSilverman is the equally alliterative Marci Maven, who is like this UpToEleven, to the point that she's furnished her house with furniture Monk threw out, and she's wearing his old pants. Apparently Monk also took out a restraining order against her.
* The ''Series/JonathanCreek'' episode "Danse Macabre" featured am obsessed fan who followed a horror writer from the US to the UK and eventually [[spoiler:cut the head off her dead body and carried back to America with him]].
* Played with in an episode of the short-lived HBO series of Tenacious D. It starts with Lee, a fan who is overly-obsessed with Tenacious D, but afterwards the Tenacious D duo becomes overly-obsessed with Lee, culminating with his murder.
* Mel in ''FlightOfTheConchords'' - president and sole member of the band's fan club and relentless stalker.
* Mandy from ''Series/ICarly''. After appearing as a guest their web show, she followed Carly, Sam, and Freddie around constantly and even switched schools to be around them, which drove them crazy. Mandy eventually became obsessed with a band and seemingly moved onto to pestering them but a more recent episode showed she was back to obsessing over iCarly.
* An episode of music group SClub7's TV series featured an annoying fan that was at first obsessed over Bradley and then later Rachel.
* Joxer from ''XenaWarriorPrincess'' initially. Xena gets a handful of other "I've studied your every move!" (sometimes followed by "Now we must fight with knives!") type of meetups, but they're generally not the following-around kind of groupies.
* In one episode of ''{{Dollhouse}}'', the title organization is hired to protect a rock star from a LoonyFan. Echo becomes a back-up singer, while another Active becomes a BigNameFan.
* In the ''Series/DoctorWho'' mini-episode "Time Crash", the Fifth and Tenth Doctors accidentally meet. Ten, delighted, immediately recognizes his former self, but Five takes him for an obsessive fan and is most annoyed.
* ''TheAmandaShow'' had Penelope Taynt (played by Amanda, herself), a nerdy fangirl and webmistress of her own Amanda fan site (which actually exists!)
* ''Series/{{Supernatural}}'' had Becky Rosen, a parody of some of the show's more extreme fans, who wrote incest fanfiction about Sam and Dean.
** She later used a LovePotion supplied by a [[DealWithTheDevil crossroads demon]] to entice Sam into marrying her. She also tied him to a bed and [[TapOnTheHead knocked him out with a waffle iron]] when he tried to escape.
* In ''Series/{{Charmed}}'', when their secret is finally revealed, they encounter a young witch who wants to join their coven. After she breaks into their house and is promptly shut down, she doesn't take it well and ends up shooting Piper.
%%* An episode of ''Series/{{NCIS}}'' had a fan of [=McGee=]'s book series was real and start killing people that resembled his characters, who are based on people he sees. This due to the fact he read some pages that stated were trying to kill the character [=McGee=]'s character.
* After G'Kar's personal diary is published (without his permission, as he hadn't finished it yet) as a holy book, in the fifth season of ''Series/BabylonFive'', he is hailed by his people as a prophet, gaining a following in the hundreds of thousands. Hundreds (at a minimum) of Narns travel to the station to learn at his feet, to his utter horror. He ends up ordering the Narn who created the G'Kar religious statuettes (which he despised) to leave him be and go back home. Shortly before G'Kar leaves the station for good (to get away from his followers), that Narn tries to shoot him and ends up wounding Garibaldi's fiancee by accident.
* Subverted in the ''ShakeItUp'' episode "Copy Kat it Up", wherein a shy, socially-awkward girl named Kat seems to have a near-stalkerish obsession with the girls, especially [=CeCe=]. [[spoiler: It turns out to be a BatmanGambit to get a spot dancing on the show]].
* The current page quote comes from a ''SaturdayNightLive'' sketch about a support group for obsessive fans of ''MrBelvedere''. They play a game called "Should and Shouldn't" which "helps keep the line between fantasy and reality a little less blurry":
-->'''Chris Farley:''' I ''should'' want to say "Hi!" to Mr. Belvedere. I ''shouldn't'' want to kidnap him and keep him in a big glass jar in my basement.\\
'''Tom Hanks:''' Okay, okay. That's good, we get that. But why? Why shouldn't you do that?\\
'''Chris Farley:''' [beat] Uh, because his breath would fog up the glass and I couldn't see him then?
* ''Series/{{Frasier}}'':
** Frasier visits one (with a StalkerShrine, no less) when he's trying to track down a tape of one of his past shows.
** In another episode, he invites his internet fanclub round to his flat, cooking an enormous buffet for them. It turns out to consist of three creepy obsessives with NoSocialSkills.
[[/folder]]

[[folder:Music]]
* Music/{{Eminem}}'s "Stan" is presented as a series of letters by a Loony Fan who takes Eminem's "Slim Shady" persona to be SeriousBusiness and tries to emulate him in every way possible... up to and including tying up his girlfriend, stuffing her in his trunk and killing both of them by crashing his car. The song ends with Eminem writing back (to said fan's second letter). Eminem writes in his reply that Stan should seek help, because his case reminds him of a news story he saw about a man who killed his pregnant girlfriend and himself afterwards, [[FridgeHorror he then suddenly realizes that Stan was the man behind the murder-suicide]].
** It's since given rise to the term "stan" to mean an overly-committed "fanboy" or "fangirl", especially the type who [[FandomRivalry bashes perceived rival fandoms]] to an unhinged degree, or utterly [[DracoInLeatherPants whitewashes their favourite character]] and [[RonTheDeathEater hates all the other characters]] on the show for being mean/insufficiently-worshipful to them.
* Maynard James Keenan of Music/{{Tool}} is said to brandish a paintball rifle when he sees fans on his lawn simply because of his experience with Loony Fans.
* Music/LadyGaga's "Paparazzi" is about such a fan.
* In rapper Plan B's concept album "The Defamation of Strickland Banks", Strickland has a drunken one-night stand with such a fan. When he rejects her afterwards, [[WoundedGazelleGambit she tells the police that he raped her]] and he's sent to jail.
* Music/TheWhiteStripes song "Take, Take, Take" is an interesting version: Jack White describes meeting Rita Hayworth at a restaurant and acting like a complete fanboy. Every action of his (seeing her, standing close to her, talking to her, etc.) ends with the words "AND THAT WAS ALL THAT I NEEDED". After every time he says it's all he needed, he thinks of something else he needs from her, until finally she gets up and leaves. "IT WAS AS IF SHE / COULD NOT APPRECIATE / HOW COOL I WAS BEING."
* "Martin Scorsese" by Music/KingMissile. The lyrics to the song are the singer impersonating a crazed fan of Creator/MartinScorsese, shouting profane lines about how he wants to meet the director and do various violent acts to him, basically just beating him to death (or at least to a bloody pulp) while thanking him for making the greatest films he's ever seen in his life. Since this trope is a large part of what drove the plot of ''Film/TheKingOfComedy'', Scorsese was likely not chosen at random as a subject.
* In the video for the Music/RedHotChiliPeppers' "By the Way", the lead singer is kidnapped by a taxi driver and has to be rescued.
* TheArrogantWorms have a song dedicated to this trope, reminding her of such things as how none of their songs are about her...except for ''this'' one. Which is ''all'' about her.
* The video for "Lego House" by Ed Sheeran. At first it appears that Rupert Grint (who resembles Sheeran) is actually playing him in the video: he mimes the lyrics, wanders Ed's trailer and house, and during the final bridge he walks up on stage to thunderous applause...at which point security run on stage and tackle him to the ground, [[TheReveal revealing him]] to be nothing more than an obsessed fan. After this reveal the shots of Grint get more disturbing (including him [[{{Squick}} eating Ed's chewing gum]]), before it ends with him being escorted out of the venue, passing the ''real'' Ed Sheeran on the way.
* As well as the video for Music/LilyAllen's "Who'd Have Known", where she kidnaps Music/EltonJohn.
* KPop group Epik High's aptly titled [[http://www.youtube.com/watch?v=eINjPkO7w4M "Fan"]] is about a "sasaeng" ("extremely obsessive") fan who kidnaps an idol and keeps him imprisoned, watching him constantly from cameras she's installed in his room, giving him "baths" ''in the washing machine'', and eventually thwarting his attempt to burn himself alive when he's inevitably DrivenToSuicide. At the end of the video, she straps him to a rocket in order to "return him to the stars" (where, as a "star," she thinks he belongs) and accidentally ends up killing him in the process. The FridgeHorror kicks in when one realizes that the girl in the video is inspired by ''real'' sasaeng fans.
* Music/{{Rainbow}}'s "Starstruck" tells the story of a crazed fan/stalker who is desperate for "a souvenir". Everyone else seems to find it funny, but Music/RonnieJamesDio doesn't.
* [[Music/{{OFWGKTA}} Tyler, the Creator's]] song "Colossus" is a "Stan"-esque song which depicts a fan as being too inspired by him to the point of annoyance and irritation on Tyler's part. Said fan also has some DepravedHomosexual thoughts in mind.
* The narrator of [[http://www.youtube.com/watch?v=RBr4XdG6lfA ''Toy Soldiers'']] by Marianas Trench.
[[/folder]]

[[folder:Professional Wrestling]]
* Wrestling/MickieJames' original gimmick in Wrestling/{{WWE}} was as Wrestling/TrishStratus's creepy stalker fan. Oddly enough, since Trish retired, Mickie's actually developed into Trish's {{Expy}}. One might think this is continuity in action, but continuity has never been WWE's strong suit.
* Wrestling/BethPhoenix picked up one of her own with Rosa Mendez.
[[/folder]]

[[folder:Video Games]]
* Sakura Kasugano was referred to by Ken as 'Ryu's stalker', and not only does she have similar moves, her alternate costume in ''VideoGame/StreetFighterIV'' has her dress almost exactly like him. Frightening.
* In ''VideoGame/TheElderScrollsIVOblivion'' the Adoring Fan ([[EverybodyCallsHimBarkeep no, that's his actual name]]) starts pestering you after you win the title of Arena champion. He's loud, obnoxious, and tends to flee from combat - but this is all intentional, due to him being a TakeThat to those who wanted multiplayer in the game. Unlike most examples of this trope, though, he will leave you alone if you tell him to ([[VideoGameCrueltyPotential even if you're both in]] [[{{Mordor}} Oblivion]]).
** Funnily enough, [[TheJester Cicero]] from ''VideoGame/TheElderScrollsVSkyrim'' apparently [[ShoutOut took on this persona]] for a job early in his career... in order to assassinate the Arena Grand Champion.
* ''Franchise/MassEffect'':
** Shepard gets one in ''VideoGame/MassEffect1'' by the name of Conrad Verner. Paragon Shepard can let him down gently, Renegade Shepard can physically assault him. If the player doesn't have enough charm or intimidate points to do either of the above, he'll run off and get killed trying to prove himself.
** In [[VideoGame/MassEffect2 the sequel]] he shows up again and says that you assaulted him, due to a save error that assumes you took the Renegade option. Since that point he's taken to dressing in a replica of your armor and acting like you did in the first game with side quests and looting. If you manage to talk him down, he'll go back to a normal life; if you upset him, he'll [[UndignifiedDeath fall into a sewage treatment plant's turbines]]. This bug gets referenced in ''VideoGame/MassEffect3'', where if you took the Paragon route in ''VideoGame/MassEffect1'', Conrad apologizes for having accused Shepard of pointing a gun at him (the Renegade option), saying he was just ''really'' stressed out at the time.
** He shows up again in [[VideoGame/MassEffect3 the final game]], this time claiming that Cerberus is an ally of Shepard, and thus the galaxy. After being set straight, Conrad eventually reveals that he has a ''StalkerShrine'' dedicated to Shepard. Alternatively, if you took the Paragon route he turns up as a doctor treating war refugees and saves Shepard from an assassination attempt, possibly dying in the process.
** In ''The Citadel'' DLC, Shepard is attacked by [[spoiler:an evil clone]]. During the final fight [[spoiler:the clone]] insists that they're better than Shepard. Shepard responds with "Are you kidding me? ''Conrad Verner'' is better at being me than you are!"
* ''VideoGame/TheSims 1'' has the Obsessed Fan, who while not quite evil can be a considerable annoyance to famous Sims.
* ''NoMoreHeroes: Desperate Struggle'' gives us Kimmy Howell, a fangirl of Travis Touchdown who eventually decides the only way to prove herself worthy of her crush is to ''kill'' him. Travis gives her a back-bodydrop and tells her to get over it.
* Amy Rose started out as a somewhat subdued variant of this towards ''SonicTheHedgehog''.
* In ''CrisisCore'', Sephiroth has a devoted group of fans who know what shampoo and conditioner he uses and how much. One must assume that they know this either because they're going through his trash or breaking into his home on a regular basis.
* In ''VideoGame/GrandTheftAutoViceCity'', a series of missions involves Tommy acting as bodyguard for a HairMetal band, Love Fist, after an obsessed fan attempts to kill them.
* In ''VideoGame/SaintsRow2'', the "Crowd Control" diversions have you protecting a celebrity from various crazy fans, who get more aggressive, more numerous, and better-armed at higher levels.

[[folder:Web Comics]]
* Seymour in ''{{Sinfest}}'', -- an ultra-religious character who goes around chiding people for not being pious enough. God [[http://www.sinfest.net/view.php?date=2000-04-28 refers to him]] as his "loony fanboy." The devil [[http://www.sinfest.net/view.php?date=2001-02-01 thinks God needs a better representation]] and likes to [[http://www.sinfest.net/view.php?date=2006-10-28 make fun of him]]. He has [[http://www.sinfest.net/view.php?date=2002-10-23 his own lame-ass fanboy]] as well. Who writes "[[http://www.sinfest.net/view.php?date=2006-09-08 Devil Fanfics]]". These two [[http://www.sinfest.net/view.php?date=2003-04-20 tend]] to be [[http://www.sinfest.net/view.php?date=2006-12-28 funnier]] together. Monique [[http://www.sinfest.net/view.php?date=2006-09-18 tried to play]] a crazy fangirl, but wasn't ready to go far enough to be believable, so she... ''outsourced'' this.
** A third fanboy was recently introduced for the third creator figure--the AuthorAvatar ("[[http://www.sinfest.net/view.php?date=2011-08-17 Will you sign my face?]]").
** Sinfest now has the first [[http://www.sinfest.net/view.php?date=2011-12-15 loony fangirl]] in a 'Nique's It-Girl persona's fangirl. Though, she is revealed to be a more benign example than the others after a chat with Monique.
* ''{{Fans}}!'' (a comic which itself focused on fans of various sci-fi / fantasy shows) played with this concept when it introduced the character of Tim the Fanboy, a geeky stereotypical 'fanboy' who was a near-obsessive fan of the main characters. Unfortunately for them, once he realized that they weren't perfect, he felt betrayed and in turn betrayed them to become the 'fan' of a psychopathic time-travelling warlord who was doing her very best to wipe them out of existence.
* Mike from ''SomethingPositive'' before his redemption. His stunts include trying to steal a tuft of Gary Gygax's beard, breaking into Nichelle Nichols's hotel room and begging her to marry him, and somehow setting fire to Steve Jackson.
* Piro and Largo's characters in the [[ShowWithinAShow Endgames]] videogame-world of ''Webcomic/MegaTokyo'' acquire a loony fan; Largo promptly [[FunnyMoments throws him off a cliff]]. As for the regular world...most of the main female characters have vast legions of stalkery fans at varying levels of creepiness (some are just obsessive, others are obsessive about collecting {{Panty Shot}}s of their idols).
[[/folder]]

[[folder:Web Original]]
* In WebVideo/TheAngryVideoGameNerd's review of the ''Franchise/TheTexasChainsawMassacre'' game, he gets kidnapped by a crazed fan and Leatherface.
* WebVideo/TheNostalgiaCritic's Douchey [=McNitpick=], a "fan" that watched all his videos 37 times solely to find all of the Critic's mistakes and harshly call him out on them.
* StupidMarioBrothers had the Crazy-obsessed-stalker-who-makes-you-unable-to-sleep-at-night Fan, as evidenced by her "Let's Get Hammered" Mario T-Shirt.
* ''Podcast/TheBrianAndJillShow'' had Jill portraying "Superfan Diane", a Loony Fan of Brian's from his KLOS radio show.
* Jim Sterling has taken some time in ''The WebVideo/{{Jimquisition}}'' to show some of the more... out there gifts that his fans have sent him. Such things include a rubber replica of a pornstar's fist, a dragon tongue dildo, and a gay furry porn comic book. The sex toys have been used for various jokes, but the comic was [[BrainBleach a bit]] ''[[BrainBleach too]]'' [[BrainBleach loony]].
[[/folder]]

[[folder:Western Animation]]
* '''Melody Juniper''' in ''WesternAnimation/TheSimpsons'' episode "Flaming Moe."
-->'''Melody''': ''(to Bart)'' I can't believe I'm playing video games with Bart Simpson. I sketched you so many times in my dream journal.
** There's also the Loony Fan of Homer's in the episode where he [[ItMakesSenseInContext becomes an opera singer]]. She [[WoundedGazelleGambit threatens to tell the police that Homer attacked her]] [[StalkerWithACrush unless he sleeps with her]], then when Homer point-blank rejects her, [[IfICantHaveYou she turns flat-out]] {{Yandere}}.
* Played for laughs in an early episode of ''WesternAnimation/HiHiPuffyAmiYumi'', "Dis-Harmony", where Ami and Yumi found themselves being followed everywhere (and I do mean ''[[TheCatCameBack everywhere]]'') by a crazy fangirl named Harmony, who would constantly remind them "I'm your #1 fan!"
* Fan Boy of ''WesternAnimation/{{Freakazoid}}'' is another example played for laughs.
* ''WesternAnimation/TheCritic'' had one of these in a direct parody of ''{{Misery}}'' - she's eventually beaten [[spoiler: [[HoistByHisOwnPetard by one of her own collectibles]], which Jay triggered by clapping]].
* Guaca in ''WesternAnimation/TheEmperorsNewSchool''. "Kuzco RULES!"
* Lorne, the "Friend for Life" (complete with his own musical jingle) who won't leave [[WesternAnimation/SamAndMaxFreelancePolice Sam and Max]] alone.
** This gets comes to a [[FunnyAneurysmMoment darker in retrospect]] head in "Fools Die on Friday", where Lorne highjacks a Swedish blimp and tries to crash into New York City in order to attract Sam and Max' attention.
* Sierra from ''WesternAnimation/TotalDrama''. She claims she knows everything about the cast, "Your hopes, your fears, '''your dental records!'''"
** Also, Kelsey, a fan contacted via webcam in ''Action'', who has made a life-size Trent doll, which she kisses, and wrote him a love poem in which she apparently plans to murder and taxidermy him.
* WesternAnimation/KimPossible's cousin Joss admired Kim so much that she dressed completely in Kim's style, had numerous pictures of Kim plastered around her room, talked about nothing except for Kim, and even accidentally made Kim fail the mission by trying to copy her in the middle of action. In the end she learned not to admire Kim that much, [[BrokenAesop so she started admiring the sidekick Ron Stoppable instead.]]
** Frugal Lucre drove Dr. Drakken to distraction with his non-stop praise and commentary while they were sharing a prison cell. After they got out of prison, he found Drakken's lair and talked him into pulling a [[VillainTeamUp joint caper]].
* ''WesternAnimation/WordGirl'' takes a spin on it: Glen emulates Dr. Two-Brains, completely fulfilling the trope in that he eventually tries to replace him... except that Two-Brains happens to be a villain himself.
* While most Decepticons are out for power, love fighting, or are just plain psycho or sadistic, Lugnut in ''WesternAnimation/TransformersAnimated'' follows Megatron because he completely idealizes him. His constant praise annoys even Megatron, who in one memorable scene actually gets a robot version of a TwitchyEye because Lugnut won't stop talking about how glorious he is instead of actually going outside and doing his job.
* Irving is so big a fan of ''WesternAnimation/PhineasAndFerb'' that he carries around a scrapbook of their adventures and often joins in their endeavors even if he's not invited. In an interesting case here, Irving started out as a one-off character but then began to recur, and shows signs of possibly becoming a SixthRanger to the boys' group of friends.
-->'''Irving:''' I got in the car when your mom stopped for gas!
* An episode of ''WesternAnimation/KaBlam'' had to do with a fan visiting the set of the show, and constantly annoying Henry and June due to his huge obsession with them. He even wears Henry's outfit, June's sweatshirt, and even has his hair blue dyed to match June's (either that or it's natural). June constantly refers to him as "Weird Ryan from school", meaning the duo already knew him.
* {{WesternAnimation/SpongeBob|SquarePants}} is like this toward famous jellyfish hunter Kevin the Sea Cucumber in the episode "I'm Your Biggest Fanatic," repeatedly invading his personal space until Kevin finally gives in to letting [=SpongeBob=] go jellyfish hunting with him and his friends. Kevin turns out to be an egotistical {{Jerkass}} who delights in humiliating [=SpongeBob=], only to have his ass handed to him when [=SpongeBob=] unexpectedly attracts the elusive King Jellyfish.
** Let's not forget how he and his pal Patrick are this to their superheroes Mermaid Man and Barnacle Boy.
-->'''Barnacle Boy:''' Holy sea cow, it's that Sponge-kid!
-->'''Mermaid Man:''' Quick lad, to the invisible boat mobile! Away!
* "[[FanNickname Foamy]]" from ''WesternAnimation/AvatarTheLastAirbender'', who appears ''[[OneSceneWonder twice]]'', is one of these. His only distinguishing characteristic is how he foams at the mouth and collapses on the ground whenever Aang is nearby. Zuko also seems to have his own in "Nightmares and Daydreams"; she has to be carted off by his guards.
* An episode of ''WesternAnimation/JimmyTwoShoes'' had a bunch of [[PandaingToTheAudience pandas]] becoming these to Heloise.
* One episode of ''WesternAnimation/RobotChicken'' has a sketch in which "Hannah Montana" gives an autograph to a crazed fan who then shoots her dead.
* Parodied in the ''WesternAnimation/{{Futurama}}'' episode "That's Lobstertainment", when Bender becomes the ''official'' stalker to robot actor Calculon.
** He does it again in ''The Beast With A Billion Backs''. Calculon asks outright if Bender's going to kill him, and Bender states that's not likely since in his mind they're friends.
** In the comic version, he [[SuspiciouslySpecificDenial specifically denies having broken into Calculon's house at night and transfused their oils so they'd always be together]].
* ''WesternAnimation/{{Archer}}'' had Ruth Anne Litzenberger as his stalker when he was a sought-after Lacrosse player. Just before she was about to seduce him, she shoots Archer and jumps out the window.
* Katrina Rad in ''WesternAnimation/TheProblemSolverz'' episode "Magic Clock". She follows the group around everywhere so she can write a blog entry about them, but she's ''really'' [[{{Yandere}} crazy]] about Roba.
* ''WesternAnimation/AdventuresOfSonicTheHedgehog'' has Sonette, who, along with changing her name, has snuck into Sonic's room while he was sleeping and stolen merchandise from him. She also is frequently seen with a piece of Sonic's chewed gum in her mouth. [[note]]Sonic had earlier claimed that he doesn't chew gum, which leads to speculation on whose gum that really is.[[/note]]
* Chessie the Autograph Hound will go through any lengths to get the autographs of WesternAnimation/TheCattanoogaCats.
* Rosie from ''WesternAnimation/ThomasTheTankEngine'' was this to the titular character in the episode "Thomas And The Birthday Mail". She tries blowing off steam and whistles the way Thomas does, which didn't suit well with him.
* Sebastian in the ''WesternAnimation/GeneratorRex'' episode "Rock My World". Attempts to force his favourite band back to its original roots and, when that fails, tries to kill them.

* Actress Rebecca Schaeffer, who starred in the 1980s family sitcom ''My Sister Sam'', was shot to death in the front lobby of her apartment building by a deranged fan.
