History Main / LoonyFan

* Music/{{BTS}} has a ''legendarily'' powerful stan community (mostly located on Website/{{Twitter}}). The majority of it is fine, but there's enough toxic users in the community that many BTS [=ARMYs=] spend more time fighting other fans for their horrible behaviour than actually celebrating the band they like.

* ''WebVideo/RealTimeFandub''''s'' version of ''VideoGame/ShadowTheHedgehog'' has Black Doom remade as The Devil ("from the Bible") who constantly nags shadow, trying to get him to do evil and go to Hell, and just constantly follows him. Multiple times The Devil recalls Shadow taking him to ''Creator/ChuckECheese'' and him getting a prize. By the end of the dub, it is revealed that Shadow [[spoiler:was genetically engineered by Gerald Robotnik to be The Devil's best friend and was Shadow's first subscriber on ''Website/{{Twitch}}''. In The Devil's mind, this justifies his obsession as Shadow owes him attention and friendship ala parasocial relationship. Unfortunately for him, [[EtTuBrute Gerald deliberately changed Shadow's programming at the last second as a joke]]]].

* The Kid in the ''[[Franchise/TheMatrix Matrix]]'' sequels is portrayed as a mild example of this.

* ''ComicBook/{{Batman}}'': The extradimensional imp ComicBook/BatMite in the wackier comics.

* ''Manga/BungoStrayDogs:'' [[NamedAfterSomeoneFamous Osamu Dazai]] takes away [[NamedAfterSomeoneFamous Ryunosuke Akutagawa]] (and presumably his sister too) from the slum, and the boy since then admires him. Akutagawa [[WellDoneSonGuy wants Dazai's approval so badly]], the first thing he does when he wakes up after Oda rescues him is ''attacking'' him because Dazai once told him he would never be strong as that man. The main reason he hates [[TheRival Atsushi]] so many years later is that said boy easily gets Dazai's recognition without needing to undergo much of the ToughLove he once suffered from.
** [[{{Irony}} Ironically]], the writers they based on has quite the opposite situation, with RL!Dazai known for being a huge fan of RL!Akutagawa. When Akutagawa died of suicide, Dazai attempted to follow suit with the same method but failed, and then tried to kill himself for the third time when he couldn't get the literary prize named after his idol.

* Being a deconstruction of the FightingSeries PlayedForLaughs, ''Manga/RamenFighterMiki'' deconstructs this trope with Akihiko, who despite being abused in 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 fond of the Red Ranger that he copies his catchphrase ''I’ll pay them back several times over'' and uses it in situations that don’t even make sense:

* Gokudera from ''Manga/Reborn2004''. 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 loony fan.
* Hayashi Rintaro, also known as Rin-rin, is the local florist on ''Manga/ShirokumaCafe''. He's also a scarily obsessive fan of pandas to the point that Panda, the resident AttentionWhore, can't stand him and all the attention that Rin-rin gives him.
* Roma Hoito from ''Manga/TokyoGhoul'', a clumsy waitress that started working at Anteiku for the chance to meet "One-Eyed Kaneki-sama". The sequel reveals her to be an even loonier fan than expected, declaring that she wants to [[spoiler: "kill" Haise because she can't stand seeing her beloved Kaneki ''happy'' and thinks he's most beautiful when his life is in ruins]].

* ''ComicBook/ThePunisherMAX'': Jenny 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 ''{{Literature/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.

* ''Manga/MyHeroAcademia'': ''[[https://archiveofourown.org/works/20955017/chapters/49822208 Listen Closely, An Angel is Dying]]'' has Present Mic kidnapped and tortured by an obsessive, psychotic one who wants to kill Mic and keep him all to himself as a ghastly “Angel” artwork. Namely by torturing him to death attaching wings and stuff ''into his flesh''. He ends up on the receiving end of the ire of an extremely pissed off Aizawa. It’s told from the villain point of view.

* ''Fanfic/SoulmateSurvey:'' The president of TeenIdol Adrien's fan club goes so far as to change her name to Adrienne to match his. She’s so intense when it comes to Adrien, her energy has driven away most of the club members. [[ManipulativeBitch Lila]] uses this to her advantage by revealing that Adrien was matched up with another girl on the titular soulmate-searching app, causing Adrienne to break down and get akumatized into Fandoom, who brainwashes anyone in her path and has a wedding set up for Adrien to "marry" her and his other fans (where [[DisproportionateRetribution she also plans to burn Marinette at the stake for being matched to him]]).

* The 2016 Indian thriller ''Film/{{Fan|2016}}'' has Creator/ShahRukhKhan playing both an example of this trope and the actor who he idolizes (possibly a NoCelebritiesWereHarmed version of [=SRK=] himself). The fan (a lookalike who is locally noted for staging impressions of the actor's films) goes to dark and dangerous lengths to try and impress the actor in question, and after being rebuffed, goes to extraordinary lengths to try and discredit him by assuming the actor's identity.

* 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.

* 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 fiancée by accident.

* ''Series/CriminalMinds'': In the episode "The Performer", the serial killer of the week was the insane fan of a singer with a vampire persona and a mental illness that made her desire to drink blood who got convinced by the singer's manager to commit murders in the name of her idol (the manager really hoped that [[NoSuchThingAsBadPublicity the spree would bring attention to the singer]] in order to bring him out of his depression. The singer, who was already sick and tired of having to pretend to be a vampire, is utterly disgusted and horrified at what the manager and the fan did; the fact that the FBI considered ''him'' a potential suspect was not really helpful, either. "TragicallyMisguidedFavor" does mot even begins to describe the understatement of the situation).

* Subverted in the ''Series/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]].

* Isabelle of ''Webcomic/MenageA3'' is one of Zii (and to a lesser extent her rock band). She dresses and styles her hair exactly like Zii, wants to be called "Izz", and for some reason thinks Zii is way more rich and famous than she actually is. She also displays a lot of StalkerWithACrush tendencies, and one point admitted to Zii's face that IJustWantToBeYou (before quickly {{Verbal Backspac|e}}ing it to "be ''like'' you").

** However in the ''WesternAnimation/PlanetSheen'' episode "Cutting the Ultra Lord", Sheen goes mental after being away from Ultra Lord for so long. When he rescues Nesmith and Doppy from a monster, he realizes that he doesn't need Ultra Lord anymore because on Zeenu, he's [[CallBack ULTRA SHEEN]]!

* ''WesternAnimation/{{Jem}}'' had a dark example in an episode where the protagonist puts some serious effort into finding Ba Nee's missing father. The Loony Fan in question was one of the three men that fit the profile (a red-haired man of a certain age who was a veteran) who was a fan of Jem and a gambling addict. He was definitely ''not'' Ba Nee's father, but learning his idol was looking for such a man caused him to shift to a {{Yandere}}-type, kidnapping Ba Nee with blackmail on his mind. (Eventually resulting in another of the three suspects - her ''actual'' father - showing up with PapaWolf intentions; it ended badly for said Loony Fan.)

* ''WesternAnimation/{{Megamind}}'' has Hal, who initially appears as a StalkerWithACrush for Roxanne. Things get worse when Megamind accidentally gives him superpowers. He thinks being a superhero will automatically make Roxanne love him, which [[SurprisinglyRealisticOutcome it doesn't.]]

* [[{{Cloudcuckoolander}} Sheldon Cooper]] in ''Series/TheBigBangTheory'' [[SurprisinglyRealisticOutcome ended up getting restraining orders]] from a lot of famous nerd celebrities for his antics, such as Creator/StanLee Creator/LeonardNimoy, Creator/CarlSagan, and Creator/BillNye.

* ''Series/CriminalMinds'': In the episode "The Performer", the serial killer of the week was the insane fan of a singer with a vampire persona and a mental illness that made her desire to drink blood who got convinced by the singer's producer to commit murders in the name of her idol (the executive really hoped that [[ThereIsNoThingLikeBadPublicity the spree would bring attention to the singer]] in order to bring him out of his depression. The singer, who was already sick and tired of having to pretend to be a vampire, is utterly disgusted and horrified at what the executive and the fan did; the fact that the FBI considered ''him'' a potential suspect was not really helpful, either. "TragicallyMisguidedFavor" does mot even begins to describe the understatement of the situation).

* ''Film/{{Backstage|2005}}'' is about Lucie (Isild Le Besco), a particularly obsessed fan (to the point of CelebCrush) of a superstar singer, Lauren Waks (Creator/EmmanuelleSeigner) who manages to make her way into Lauren's inner circle and even has an affair with Lauren's ex, and SanitySlippage ensues. There are also entire groups of fans camping outside the hotel Lauren has a stay in (they even shout at 4am) and an unhinged mob waiting for Lauren at one point (one fan even spits at her car's window out of jealousy for Lucie).

** "Stan" [[https://youtu.be/gOMhN-hfMtY is presented as a series of letters]] by the titular 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 afterward, [[FridgeHorror he then suddenly realizes that Stan was the man behind the murder-suicide]]. It's since given rise to [[PersonAsVerb the term "stan" to mean an overly-committed and toxic fan]]. Over time, the term "stan" as a means of pointing out obsessive and over-the-top fan behavior has become diluted due to "stan" being used as synonymous with fandom culture regardless of toxicity.

This can also overlap with the StrawFan, TheCollector, {{Yandere}}, ShipperOnDeck, PsychoSupporter, or StalkerWithACrush. Commonly known to say "ImYourBiggestFan". Compare ActorRoleConfusion, CannotTellFictionFromReality. Contrast with AscendedFanboy.

* ''VideoGame/SonicTheHedgehog'':
%% ** Amy Rose started out as a somewhat subdued variant of this towards Sonic.
** ''VideoGame/SonicTheHedgehog2006'' brings us SONICMAN! He's so convinced he's the real Sonic, he ''challenges the real Sonic to a foot race!''
