History EnsembleDarkHorse / WesternAnimation

** Fans have rather warmed up to Maddie's sisters Rosemary, Lavender, and Ginger. Them being playful and sometimes mischievous triplets brings to mind [[ComicBook/DisneyDucksComicUniverse Huey, Dewey, and Louie]] for quite a number of fans.

** Blendin Blandin, the time traveller who goes after Dipper and Mabel is popular for being a ButtMonkey DesignatedVillain. Being voiced by Justin Roiland using his [[WesternAnimation/AdventureTime Lemongrab]]/[[WesternAnimation/RickAndMorty Morty]] voice helps
** Rumble McSkirmish, a [[Franchise/StreetFighter Ryu Expy is popular for his [[NonStandardCharacterDesign unique visual style]], being an Affectionate Parody of video games of different genres and also being a DeconstructiveParody on [[RefugeeFromTVLand what would happen if such a character would end up in the real world]]. Being one of the few "monsters" to experience CharacterDevelopment helps as well.
** Mermando is arguably the most popular GuyOfTheWeekForMabel, since they have genuine chemistry and he's actually sincere in his love for her. Plus, he's a hilarious parody of a ParanormalRomance.
** Carla McCorkle, who only appears in two episodes, and even then, only in flashbacks or memories, and has essentially no bearing on the plot, however she's certainly the fan favourite of Stan's referenced/implied love interests, and their relationship is often portrayed in fanworks as having been extremely significant.

** [[BreadEggsBreadedEggs Bipper]] ([[BigBad Bill Cipher]]'s [[DemonicPossession possession of Dipper's body]]) became widely popular among fans.
** .GIFfany, a DatingSim character who gained sentience and developed {{Yandere}} tendencies towards her players. She's probably ''the'' most popular MonsterOfTheWeek, enough so that ''Literature/GravityFallsJournal3'' has her still alive and paired off with Rumble, much to the joy of many fans.

** Mabel's friend [[{{Adorkable}} Candy Chiu]] has also picked up quite a following, most likely because her EstablishingCharacterMoment involves ''forks taped to her fingers''. And maybe because she shares a voice actress with fellow darkhorses [[WesternAnimation/AdventureTime BMO and Lady Rainicorn]].
** Giffany, the {{yandere}} {{AI|IsACrapshoot}} from "Soos and the Real Girl," gained a lot of fanart within a mere week after her debut.

** Pyronica is easily the most popular of Bill's minions, despite her limited screentime.

** Hilda's great-aunt Astrid. Many fans enjoyed her for basically being the {{Expy}} of [[WesternAnimation/GravityFalls Grunkle Stan]].

** Hilda's great-aunt Astrid. Many fans enjoyed her for basically being the {{Expy}} of [[GravityFalls Grunkle Stan]].

** Waddles, Mabel's [[RidiculouslyCuteCritter cute pet pig]] had become a fan favorite.

** While he had a handful of fans beforehand, Robbie V became this since the events in "The Love God" revealed him to be just a goofy, maladjusted, insecure teenager with very... interesting parents.
** [[AlphaBitch Pacifica Northwest]] has also become this, [[JerkassDissonance much to the surprise of creator Alex Hirsch]]. This is why Season 2 has been giving her more CharacterDevelopment, revealing that she has a FreudianExcuse for her behavior ([[spoiler: her parents being horrible people]]) and setting up a DefrostingIceQueen storyline.

** Tildy has been similarly well-received, not only for being the former mentor of Kaisa, but for being a sweet, understanding CoolOldLady, who offers to teach Frida magic.

%%** Hilda's great-aunt Astrid became popular with fans

** Despite Louise having major role in only one episode, many fans ended up loving her due to her quiet and observant personality and her fun dynamic with Hilda, Frida and David. [[TheyWastedAPerfectlyGoodCharacter Many fans ended up wishing she got more time in the spotlight]].

* Yuck from ''WesternAnimation/YinYangYo'' is the {{evil counterpart}} of Yin and Yang whose both a ManipulativeBastard and a {{Jerkass}}. He only appears in six episodes total throughout the whole series yet that doesn't stop him from having a much larger fanbase than the main characters. Though other villains such as Carl and Smoke are fairly well liked, he is arguably the most popular. His tension with Yin in "Falling Yin Love" and HeelFaceRevolvingDoor in "Upstanding Yuck" only add on to this.

** A few fans found the butter boy aka "Butterfingers" pretty interesting. A villain who motivation was wanting to be a superhero but resorted to un-superhero like methods (i.e. stealing Buttercup's body) because the power he gained wasn't to his liking. The fact that he has a very skewed perception of superhero-ing (solely just fighting bad guys for action rather than protecting people) and willing to kill to keep Buttercup's body was a factor too.

* ''WesternAnimation/StormHawks'': Suzy Lu and the Absolute Zeroes have some of a fanbase, due to their memorable CloudCuckoolander antics and taking their [[CanadaEh Canadian pastiche]] to amusing levels, while Suzy Lu herself is a rather likeable CoolBigSis-type character. It helps that the Blizzarians' unique design helps them stand out despite their limited screen time.

* ''WesternAnimation/ThePenguinsOfMadagascar'': Buck Rockgut only appears in three episodes but is largely regarded as one of the most memorable characters of the series, thanks to his paranoic personality, solid voice acting from ''Creator/ClancyBrown'', providing one of the show's most memorable gags ("THE RED SQUIRREL") and [[spoiler: [[TheCuckoolanderWasRight actually being kinda right about the Red Squirell being a thing]]. ]]

* ''WesternAnimation/AdventureTime'':
** The Demon Cat from "Dungeon" is very popular despite only appearing in that episode. It helps that its "approximate knowledge of many things" line was subject to MemeticMutation.
** Breakfast Princess is a minor princess, but her cute design garnered her a lot of fans.
** The ''entire'' {{Gender Flip}}ped world rivaled the normal one in popularity even before "Fionna and Cake" was made. Special props, however, go to Marshall Lee, who is arguably the most popular one of all, despite his only appearance in that episode being a silent [[TheCameo cameo]]. The episode dedicated to him increased his popularity a billion fold, especially because he's genuinely much more of a mischievous, traditional [[TheTrickster trickster]] than Marceline is.
** ''Any'' character that is female, young, and has a fit humanoid body, including Celina, Doctor Princess, Jungle Princess, the Nymphs, the Bikini Girls and others, generally for fanart, shipping and [[RuleThirtyFour Rule 34]].
** Jake's dad, Joshua, seems to be rather popular for how crazy awesome he is.
** Before "Jake the Dad" aired, of Jake and Lady Rainicorn's kids, Jake Jr. seemed to be getting the most attention and concern, because the kid lacks a face.
** Shoko got plenty of fanart after her debut. Probably because of her [[TheWoobie sad life]] and being voiced by Creator/IsabelleFuhrman.
** Rosalinen from "Puhoy" is also quite popular, in part to the fact that Finn forgot all about her and their children.
** James from "James" seems to have a very loving fan base as well. It helps that, coupled with his funny mannerisms that he's voiced by [[WesternAnimation/SpaceGhostCoastToCoast Brak]].
** During "Five Short Tables", Ice Queen is revealed to also be writing {{Gender Flip}} fan fiction about Fionna and Cake, her fanfic focus on Flynn and Jacques, a gloomy looking boy with bangs covering one eye and wearing formal clothes with his raccoon friend, both got popular instantly. Even Ice President got some fan art and ''his'' GenderFlip fanfiction characters, Lynn and Janet also became popular.

* ''WesternAnimation/AtomicPuppet''

* ''WesternAnimation/AquaTeenHungerForce'':
** The Mooninites are easily the most fondly remembered and quoted villains.
** The Plutonians are similarly fondly remembered, though not to the Mooninites' extent.
** The Cybernetic Ghost of Christmas Past from the Future for his utterly nonsensical {{Exposition Dump}}s.
** Jiggle Billy, to the point where his face has reached MemeticMutation status.
** Handbanana, for being such a [[CrossesTheLineTwice hilariously messed up]] [[BlackComedyRape concept]].
** Shake's Muscles, helps that Creator/JohnDiMaggio voiced him.

** [[SpellMyNameWithAnS Lahwhinie/Lawhinie/Louwhiney]]. She only appears in "Gadget Goes Hawaiian", but she's essentially Gadget's {{Doppelganger}}, a kind of Gadget in a sarong wearing make-up and a flower in her hair. Yes, she's a villain. No, she is not redeemed in that single episode of hers. But she technically is even more of a looker than Gadget with lots of FanArt to prove, and she's pure CanonFodder for the Rangerdom's ever-productive FanFic writers: How come there's a mouse in UsefulNotes/{{Hawaii}} that looks almost exactly like Gadget? Even if they don't try to answer the question whether she's Gadget's LongLostSibling or even EvilTwin, they can still bring her back as a Gadget impostor.

* ''WesternAnimation/CloneHigh''

** Clone Hitler only appears in a small cameo, but he is liked by the fandom as he seems to have gone a different path then his clone, wearing a peace sign armband.

** Sector Z! After five minutes of screentime in the movie they won the hearts of a sizeable portion of the fanbase with their badassery. It probably helps that they [[spoiler: were the Delightful Children from Down the Lane before they were BrainwashedAndCrazy.]]

* ''WesternAnimation/DextersLaboratory'':
** Lisa the babysitter. She only appears in a very early episode of the series and never shows up again after that. But look up any fanart of her and you'd be surprised at how much of it there is. [[HartmanHips Guess]] [[{{Fanservice}} why.]]
** For similar reason The Touchy-Feely Neighbor Lady and Candi, the Dee Dee replacement, are widely remembered despite only appearing in one episode.
** Mandark's abrasive younger sister and Dee Dee's rival-turned-friend Lalavava only appeared in [[OneSceneWonder one episode,]] yet has a substantial amount of fanart, enough to have gained her own category in some fandom groups for the show.
** Lee-Lee, one of Dee-Dee's friends, is one of these.
** Douglas Mordecai, one of Dexter's friends, despite being a borderline SatelliteCharacter in canon. Maybe just because he was the only character Dexter could talk to like a human being.
** Val Halen has a ''ton'' of fangirls.
** The Puppet Pals. Some people wished they had their own SpinOff.
** The robot parrot from the episode "The Parrot Trap", thanks to being a FountainOfMemes with lines such as "Dexter is a cookie!".

* ''WesternAnimation/{{Freakazoid}}'' had JustForFun/{{Candlejack}}, a one off character. To explain: He's just a boogeyman who kidnaps anyone who says his name but is just a one-off villain rather than being a recurring member of Freakazoid's RoguesGallery. He ends up spawning a massive MemeticMutation that even at one point permeated Website/ThisVeryWiki due to how easily applicable it is within internet wiki/forums until he's contained in the previous Just For Fun link (just click it to see how it works), and thus he became way too memorable for a one-shot villain.

* ''WesternAnimation/InfinityTrain'':
** Spokesperson!Atticus and Actress!One-One. They are only there for a quick joke in Episode 5, but are very memorable for the sheer absurdity of it.
*** On a similar note, Mirror!Atticus and Mirror!One-One are a (One-)OneSceneWonder, due to establishing that Car inhabitant reflections have opposite personalities, which is technically FanficFuel.
** "Good Guy" and "Bad Guy" from Tulip's game are really just background decoration, but they stuck with fans, to the point that they are official icons on the show's subreddit.
** Randall has gotten a lot of recognition for being a friendly, sentient water puddle who is completely willing to help Tulip catch up with the Cat. Some would've liked to see him as the fourth party member, but that would've been too many characters to juggle. He becomes a recurring character appearing in one of the Train Shorts and an episode in Book 2 and 3.
** Nancy only appeared in one episode, and only at the very beginning at that, but fans remember her for her friendly personality and CreepyCute design. She returns for a small cameo in "The Lucky Cat Car".
** Mikayla is completely irrelevant to the plot of the series, but many fans like her since [[TrueCompanions she's a legitimately good friend to Tulip]].
** [[spoiler:Alrick is only really important for the Conductor's backstory, but many fans understand why she was in love with him so much, since he was an {{Adorkable}} goofball who reliably stayed by her side throughout their entire lives.]]
** Frank the Bear only appears briefly in Book 3, but many fans love him for being a MomentKiller and a genuine NiceGuy.
** The Chandelier Escort from "The Debutante Ball Car" gets a lot of love for his design and voice, despite only appearing briefly.

* ''WesternAnimation/OKKOLetsBeHeroes''

* ''Franchise/SonicTheHedgehog'' cartoons:
** ''WesternAnimation/AdventuresOfSonicTheHedgehog''
*** [[MsFanservice Breezie]] [[LadyInRed for obvious reasons]]. [[Creator/ArchieComics Archie]] took notice and incorporated her into the [[ComicBook/SonicTheHedgehogArchieComics comics]] post-reboot.
*** As well as the other MsFanservice Katella who appeared in only one episode. Many fans still make fanart of her.
*** The bounty hunters from "Sonic Search and Smash Squad", largely due to their reappearance in VideoGame/DoctorRobotniksMeanBeanMachine, a rather extreme example of this since outside the game, most of the characters only appear for all of a couple of seconds in the show itself or at best make a few cameos in other episodes as foot-robots.
** Wes Weasley is a very popular character for his charismatic SnakeOilSalesman antics that usually turn out well for him, to the point where many fans like to reimagine him in the games' art style.
** ''WesternAnimation/SonicTheHedgehogSatAM'':
*** Bunnie Rabbot arguably had the least spotlight of the main Freedom Fighters, acting as a bit player at best in every appearance, is popular for her cyborg powers and is one of the few alternate media ''Sonic'' characters not to gain much disdain, compared to how Sally Acorn is [[BaseBreakingCharacter more infamously divisive]].
*** Lupe, the leader of the Wolf Pack, is also popular in the fandom despite having only one episode devoted to her.
** ''WesternAnimation/SonicUnderground'':
*** Mindy [=LaTour=] only appeared once, but she's a popular character for being childhood friends with Sonia, having an interesting character design, and being the only non-band member to sing lead vocals.
*** '''[[WebVideo/{{Tamers12345}} Bartleby]].'''
*** Sonia and Manic could be considered this for the entire franchise, as many fans do like them and use them in fan works, even if they are not familiar with or even fans of ''Sonic Underground'' as a whole.
** ''WesternAnimation/SonicBoom'':
*** From across both ''Rise of Lyric'' and the show, Perci became a popular character due to her design. She is a minor character whose original intentions [[WhatCouldHaveBeen were cut from the game]], and she is one of the few ''Rise of Lyric'' non-playable characters to appear in the show, with [[Recap/SonicBoomS1E43FireinaCrowdedWorkshop an episode]] dedicated to her appearance.
*** Several of the Lightning Bolt Club members have become popular, due to being even more {{Ineffectual Sympathetic Villain}}s than Eggman.
*** Mark the Tapir, almost to JustHereForGodzilla levels, for being a hilarious TakeThatAudience towards the fandom's toxic VocalMinority. The fact a lot of people have compared him with [[Webcomic/{{Sonichu}} Chris-Chan]] doesn't hurt, even if the creators say the similarity wasn't intended.
*** Metal Sonic was extremely popular in both of his appearances, especially in the Season 2 finale where he beats the living daylights out of Sonic and Shadow with very little effort.
*** Zooey is also popular, mostly because [[{{Moe}} people find her and her relationship with Tails adorable]]. There even are FanWorks based on the [[ComicBook/SonicTheHedgehogArchieComics Archie Comics]] which has Zooey as a CanonImmigrant to the comics.

---> '''World's Biggest Fan''': And when is Fifi going to get her own series?

* Odlaw from the ''[[Literature/WheresWally Where's Waldo?]]'' cartoon series seems more well-liked than Waldo himself. To a lesser extent, Woof could qualify as this.

** Among all the fairy forms, the Enchantix seems to be the most popular, not only for being cute, but also because the requirement necessary to unlock it is a source of development and interesting storylines. Many fan-created original transformations out there are clearly based on Enchantix or include its main characteristics (like having shinier wings, sporting elaborate jewelry, and going barefoot or in some kind of sandals). The announcement that Enchantix would return in Season 8 made fans ''very'' happy, until [[TheyChangedItNowItSucks they saw]] [[{{bowdlerize}} how it had been changed]].

** Pyronica is easily the most popular of Bill's minions, despite her limited screentime, because of EvilIsSexy.

** Agent Kalashnikov, if only for [[EvilIsSexy one reason]].

** Among the RoguesGallery, Professor Tite-Gripp and Naughty Kitty are probably the most popular, with the latter often falling under EvilIsSexy due to being a Cat Girl based on Eartha Kitt and Sofia Vergara.

* ''EnsembleDarkHorse/TheVentureBrothers''

** Sissi and Jim started out as comic-relief antagonistic characters, but became more frequent allies through CharacterDevelopment and
[[RescuedFromTheScrappyHeap won many fans over.]] Even WordOfGod has expressed affection for them.

* Atsuko from ''WesternAnimation/InspectorGadget''; a one-shot character from the episode "The Japanese Connection," she is basically the Japanese equivalent of Penny, (only with no Brain or Gadget counterparts) a {{Moe}}, GadgeteerGenius who fights a Japanese Dr. Claw {{Expy}}. She appears frequently in fanworks as a friend of Penny's so you'd be forgiven for thinking she was a RecurringCharacter. [[note]] Admittedly, much of this work involves her being captured & BoundAndGagged alongside Penny, but still, more than you would expect a one-shot character to have. [[/note]] Similarly, Sonya [[note]] [[ViewerNameConfusion occasionally misheard as Anya]] [[/note]] the gypsy girl from "Prince of the Gypsies," who is often partnered with the other two in a sort of ThreeAmigos situation, but not to the level of Atsuko.
