What happens when a MythologyGag and a {{Cameo}} decide they [[{{JustForFun/Troperithmetic}} love each other and have a baby.]]

A ContinuityCameo sticks a character from another continuity (usually the manga, comic, original game, novel, etc.) in the work as a wink to the fans. Sometimes this is done as an apology to the fans for [[AdaptedOut leaving their favorite character out]] and as a way of saying that they do exist in that particular universe even if they're not focused on. Most of the time you either have to know it's there or know what to look for, as they sometimes go by so fast that you'll literally miss them if you blink.

This trope is mostly used in JapaneseMedia and Western ComicBooks, with their often vast and overlapping continuities. This can have originally have been a ChekhovsGunman that wasn't able to be followed through due to cancellation of the series or the result of an AbortedArc.

Compare with the AdaptationalEarlyAppearance, where a character who appears late in the original appears earlier in a cameo in the adaptation, and RemakeCameo, where people involved with an original work make a cameo in its remake. Contrast AscendedExtra. See also LastEpisodeNewCharacter.


[[folder:Anime & Manga]]
* ''VideoGame/DigimonAdventureAnodeCathodeTamer'': Ryo Akiyama's appearances in the second ''Anime/DigimonAdventure'' film and ''Anime/DigimonAdventure02'' fall under this, although he becomes a full-fledged CanonImmigrant in ''[[Anime/DigimonTamers Tamers]]''. Particularly confusing to Western audiences, as the video games in which he stars were never released here.
** Ryo is clearly an example of "don't think about it too much or you'll get a headache," 'cause he and his Digimon work under slightly different rules than the other Tamers, what with being from a completely different universe and all....
** Another example would be the Autumn Leaf Fair in ''Frontier''; the background characters are all Digimon that appeared in the first three series.
* In the ''VisualNovel/{{Air}}'' movie, Kano, Minagi and Michiru make cameos during the festival. They're the other heroines in the original game and anime series, but the movie is a Misuzu exclusive storyline.
** In the TV series, Ayu, Nayuki and Makoto from ''VisualNovel/{{Kanon}}'' appear at Misuzu's school. Creator/KyotoAnimation would eventually animate that series as well, making it double as ProductionForeshadowing.
* Kareha's sister Tsubomi in ''VisualNovel/{{Shuffle}}'' shows up in the last episode. As an added joke, she's reading Asa's character novel.
* Arika shows up very briefly at the very end of both the ''Anime/MaiHime'' anime series and manga, and Nina can be spotted sitting in the desk in front of Tate's in the classroom in episode 2. They're the main characters in the ElseWorld [[labelnote:(?)]](or maybe distant-future)[[/labelnote]] sequel ''Anime/MaiOtome''.
* In the ''VisualNovel/FateStayNight'' anime series, Zoken Matou shows up very briefly, and we just see the bottom half of his face. He is major character in a route the series doesn't follow.
* It won't be until (or really, when) a third season comes out that we'll know if Kirakisho's appearance at the very end of the second season of ''Manga/RozenMaiden'' was one of these or a ChekhovsGunman.
** As it turns out, it's one of these, as the third season's in a different continuity.
* ''Manga/MermaidMelodyPichiPichiPitch'' did this in reverse: When the anime came out and added Kura-chan, a new mascot character, the mangaka decided to put him in one panel as a nod.
* The ''Anime/MagicalShoppingArcadeAbenobashi'' anime series manga character Ochi-san shows up ''very'' briefly in the last episode.
* Beri Shirayuki makes an appearance in the last volume of the original ''Manga/TokyoMewMew''.
* Creator/{{CLAMP}} loves to do this with their works using TheMultiverse, but a few with the same characters also occur:
** In ''Manga/XxxHOLiC'' Watanuki goes to the ''Legal Drug'' store and sees the two leads of that manga, and later the said two leads end up at the wish store in their own series as well.
*** He also finds [[Manga/CardcaptorSakura Sakura' staff]] in Yuko's storeroom in the first volume of the story. [[spoiler: Except it's less a continuity cameo and more of a ''massive'' ChekhovsGun.]]
** Fujimoto from ''Manga/{{Kobato}}'' is also seen working at the ''Legal Drug'' store promoting cough medicine.
** Though they aren't actually seen, Yuuko also mentions Subaru and Hokuto, characters from ''Manga/TokyoBabylon'' and ''Manga/{{X1999}}'' and says that she's known them since they were children.
** And in ''X/1999'', older versions of Nokoru, Suoh and Akira, the three lead characters from ''Manga/CLAMPSchoolDetectives'', now run the CLAMP Campus.
* Oddly enough, ''Anime/RebuildOfEvangelion'' has a ContinuityCameo in [[spoiler:Kaworu, in that he appears to have full memory of the events of [[Anime/NeonGenesisEvangelion the original series]].]]
* Kaede, Satsuki and Aoi from the ''Manga/ShinjiIkariRaisingProject'' video game make a cameo appearance in ''Manga/NeonGenesisEvangelionCampusApocalypse'' as nuns at Shinji's school.
* In ''Manga/LoveHina'', Naru's sister was originally made for the anime adaptation, but Ken Akamatsu loved the character so much that he included her in the manga in the final chapter... and then used her ''again'' in ''Manga/MahouSenseiNegima'', making many fans wonder if they're not both the same girl and if the two series have a shared continuity.
** ''Negima'' has a number of cameos from ''Love Hina''. Motoko seems to appear in one of Setsuna's flashbacks, and WordOfGod confirmed that the inn the group stayed at during one of the {{Beach Episode}}s is the same as the one at which Naru and Keitaro stayed. Then there's the fact that Motoko and Setsuna are both practitioners of the same sword style...
*** In chapter 256 Motoko's family is mentioned by name, and one the techniques Motoko used in ''Love Hina'' seems to be somewhat plot-relevant in ''Negima''.
*** And Tsukuyomi uses the [[spoiler: [[EvilWeapon Hina Blade]] from Love Hina.]]
* Ogiue appeared at the very end of the credits of the last episode of the first season of ''Manga/{{Genshiken}}'' -- she wouldn't appear for real until the OVA.
* Ittou Asanuma, a minor (but still important enough to know the Senshi's secret identities) recurring character from the ''Manga/SailorMoon'' manga appears briefly in one episode of ''Anime/SailorMoon Sailor Stars'' where he calls on Mamoru when he misses a get together of the members of a PC Network. When Mamoru doesn't appear to be home he leaves. We only know it's him because of the credits.
* [[Anime/FullmetalAlchemist The 2003 anime version]] of ''Manga/FullmetalAlchemist'' includes a cameo shot of Ling Yao, a character solely from the manga, as a state alchemist participating in the Ishvalan genocide. He also happens to be wearing sunglasses in the same style as Greed's, in reference to [[spoiler:Ling becoming the second Greed.]]
** And late in ''Brotherhood'', there's a shot of an elderly couple -- the female looks exactly like old Dante.
* ''Manga/MajinTanteiNougamiNeuro'' had cameo shots of Ai and [[TokenMiniMoe Miyasako Mutsuki]] with her grandfather. The [[LastEpisodeNewCharacter credits]] also had shots of Shizuka Todoroki and Tateo Mochizuki.
* ''Anime/{{Pokemon}}'':
** In three of the anime [[TheMovie movies]], Brendan (the male playable character from Ruby/Sapphire/Emerald) briefly shows up during the opening narration sequences, though never in-focus. Several other characters from the games make similar cameos in the other movies and [=OVA=]s .
** Outside of the movies, [[Manga/PocketMonsters Isamu Akai]] (the ''other'' character based on Red, who is ''nicknamed'' Red), his obnoxious talking "Blockhead Clefairy", and Pikachu, stars of the ''Manga/PocketMonsters'' gag manga makes a cameo in a movie the main cast goes out of their way to get to be shown to an out-of-the-way village (oddly enough, the manga then had a chapter about Clefairy making his first appearance in the anime).
** Chapter 7 of ''Manga/TheElectricTaleOfPikachu'' doesn't actually adapt any specific episode of the ''{{Anime/Pokemon}}'' anime, instead having a collection of cameos of characters and allusions to events from over half a dozen different episodes.
** [[Videogame/PokemonDiamondAndPearl Lucas,]] [[Videogame/PokemonSnap Todd Snap,]] and [[VideoGame/PokemonGoldAndSilver Ethan and Silver]] make appearances in these adaptations as well.
** A separate character based on Ethan (Jimmy) [[AndNowForSomeoneCompletelyDifferent gets]] [[Anime/TheLegendOfThunder his own episode]] however, appearing alongside Kris (Marina).
* In ''Anime/CodeGeass'', the Lancelot powersuit from AlternateContinuity manga ''Suzaku of the Counterattack'' makes a brief appearance in one episode. Additionally, the VisualNovel spinoff ''Lost Colors'' has references to the Nintendo DS game and ''Nightmare of Nunnally'', another of the manga. Not only that, Rai, the protagonist of ''Lost Colors'', eventually makes a cameo in an episode of the second season.
* Kaitou Kid starts making several appearances in ''Manga/DetectiveConan'' after Gosho's work on the earlier ''Magic Kaito'' series was halted. They're arguably in the exact same world, although ''Magic Kaitou'' contained more supernatural situations.
* Frederica Bernkastel from ''VisualNovel/UminekoWhenTheyCry'' appeared at the end of ''VisualNovel/HigurashiWhenTheyCry'' Kai. [[spoiler: We also hear her voice at the end of each first season episode; She's the girl in the previews]]. ''Yes'', that wasn't Rika grown up. [[spoiler:But technically, Bernkastel ''is'' Rika, or at least, all of the dead Rikas combined in one entity.]]
** Becomes pretty significant, considering the possible relationship between [[spoiler:Miyoko Tanashi and Lambdadelta, as well as Bernkastel becoming a FallenHero]].
* ''Anime/DragonBallZ'': Goku's father Bardock first appeared on a TV special, but Toriyama liked him so much he gave Bardock a small (two panels) appearance in the manga.
* ''Anime/TengenToppaGurrenLagann'' has an episode where female characters from various Creator/StudioGainax productions ranging from ''Anime/NeonGenesisEvangelion'' and ''Anime/DieBuster'' to ''Manga/{{Mahoromatic}}'' can be seen as employees at a bathhouse the protagonists visit.
* Several characters from ''Anime/NeonGenesisEvangelion'' cameo as toys in an episode of ''Anime/HanamaruKindergarten'', another Creator/StudioGainax TV series.
* Akuma makes a "blink and you miss it" cameo appearance in ''Anime/StreetFighterIITheAnimatedMovie'', where he can be seen during the Calcutta scene before the Dhalsim and Honda fight.
** In the ''Street Fighter II V'' television series, Akuma can also be seen during various crowd scenes throughout the series.
** A much less prominent example, the second version of the ''Street Fighter II V'' opening intro has Balrog wearing his boxing gear from the game (which he never does in the actual show), as well as a brief glimpses of T. Hawk getting hurricane kicked to the face by Ken. Apparently T. Hawk was supposed to be on the show alongside Dee-Jay, Blanka and E. Honda, but the anime was canceled before they could get to their episodes.
* In ''Shin Getter Robo Vs Neo Getter Robo'', Michiru Saotome, Genki Saotome and Benkei Kuruma all show up in the credits of the final episode (the Saotomes were absent throughout the series and Benkei never showed up due to ''Manga/GetterRobo G'' getting averted).
* Probably the biggest one is in ''Anime/MobileFighterGGundam'', where virtually every major Mobile Suit of the Universal Century, as well as a number of non-Gundam mecha such as L Gaim and Zambot3, show up to battle the Devil Gundam at the very end. Also important as there was the first appearance of a certain [[Anime/MobileSuitGundamWing transforming, Buster Rifle-using Gundam]].
** The original Gundam also makes a cameo near the end of ''Anime/SpaceRunawayIdeon'', another series created by Creator/YoshiyukiTomino.
* In the ''Manga/FistOfTheNorthStar'' movie ''Legend of Kenshiro'', the fifth installment of the ''Legends of the True Savior'' series, Ryuga and Juza are among the spirits of fallen warriors who are attending Kenshiro and Yuria's wedding. They were the only characters in that scene up to that point who were absent from the movies (although Ryuga technically did appear as a child in ''Legend of Yuria'', as well as spirit in ''Legend of Raoh: Chapter of Fierce Fight'').
* Issac and Miria from ''LightNovel/{{Baccano}}'' make a cameo in TheClimax of ''LightNovel/{{Durarara}}''. This could also be considered a ContinuityNod, seeing as the two series are set in the same universe.
* In the anime version of the Loguetown arc in ''Manga/OnePiece'', Crescent Moon Galley, the villain from the first version of ''[[WhatCouldHaveBeen Romance Dawn]]'', makes a minor appearance.
** It doesn't exactly fit the description, but Vice Admiral Jonathan, the WorthyAdversary antagonist of the G-8 Arc, the most popular filler arc, makes a quick appearance during the marine forces' gathering just before Marineford.
* Disregarding [[{{Transplant}} Plue]], various ''Manga/RaveMaster'' characters will pop up in crowd scenes in ''Manga/FairyTail''.
** FillerVillain Daphne is briefly seen in prison during episode 114.
* ''Manga/{{Trigun}} Maximum'' had one scene early on in the 12th volume where Vash flashes back to ''everyone'' he's met in the past -- including characters who had previously only appeared in the anime, such as Loose Ruth (a rogue bounty hunter from the first episode) and Marianne (an undercover agent Vash has a crush on in the anime's second episode)
* ''Manga/BlueExorcist: TheMovie'' features a brief cameo from Renzo Shima's older brothers, Juzo and Kinzo, who were introduced in the Kyoto arc of the manga. (The anime's GeckoEnding split off before the series reached that point.)
* TheStinger for Anime/GravestoneOfDaisukeJigen reveals that [[spoiler:the owner of the club is none other than [[TheMysteryOfMamo Mamo]],]] establishing that the movie is not only a prequel to Anime/LupinIIIGreenJacket, but a StealthPrequel to [[spoiler: the first animated Lupin film.]]
* In the penultimate chapter of the YuGiOhZexal manga, Astral summons a bunch of Numbers that before this have never appeared in the manga, but all [[http://yugioh.wikia.com/wiki/No._9:_Dyson_Sphere_(manga) had]] [[http://yugioh.wikia.com/wiki/No._40:_Gimmick_Puppet_of_Strings_(manga) prominent]] [[http://yugioh.wikia.com/wiki/No._46:_Dragluon_(manga) positions]] [[http://yugioh.wikia.com/wiki/No._61:_Volcasaurus_(manga) in]] [[http://yugioh.wikia.com/wiki/No._66:_Master_Key_Beetle_(manga) the]] [[http://yugioh.wikia.com/wiki/No._6:_Chronomaly_Atlandis_(manga) anime]].
* While she really doesn't have much screen time, in ''Anime/YourName'', Mitsuha's literature teacher is Yukari from ''Anime/TheGardenOfWords'', showing that [[spoiler:she left Tokyo and went to Itomori after separating with Takao. This became somewhat HarsherInHindsight as before Taki and Mitsuha rewrote the timeline, she is likely to be one of the casualties when the comet fragment hit and destroyed Itomori. Yukari is later shown briefly in the WhereAreTheyNowEpilogue near the end of the film where she is living in Tokyo again, hinting that she might be able to meet again with Takao.]]

[[folder:Card Games]]
* Several cards from the ''TabletopGame/YuGiOh'' OCG have characters from the anime or manga on them:
** [[http://yugioh.wikia.com/wiki/Unity Unity]]: [[Anime/YuGiOh Yugi, Joey/Jonoichi, Tea/Anzu, Tristan/Honda and Duke]]

[[folder:Comic Book]]
* The ''ComicBook/MegaMan'' comic had a cameo of Neige from ''VideoGame/MegaManZero'' in the first issue, which took place during the first game in the [[VideoGame/MegaMan Classic series]].

[[folder:Fan Works]]
* ''FanFic/TheCaptainOfTheVirtualConsole'' has a Pokemon world primarily based on the games, but Yellow from ''Manga/PokemonAdventures'' appears.
* In ''Fanfic/HowToDrillYourWayThroughYourProblems'', [[spoiler:Kamina appears to Taylor while she's trapped on the roof in [[https://forums.spacebattles.com/posts/35223613/ Sithking Zero's omake]], which is confirmed to be at least semi-canon in the Taylor Interlude.]]

[[folder:Films -- Animation]]
* Creator/{{Pixar}} loves this trope. Outside of their love of EarlyBirdCameo entries, there's a few other instances of these:
** When Sully and Boo return to her room at the end of ''WesternAnimation/MonstersInc'', she has a toy [[WesternAnimation/ToyStory2 Jessie]].
** The mobile home that Mike and Sully send Randall to appeared in ''WesternAnimation/ABugsLife''.
** At the end of ''WesternAnimation/{{Cars}}'' the characters watch scenes from several older Pixar movies (with the characters replaced with cars of course).
*** The small birds from the [[WesternAnimation/PixarShorts Pixar Short]] ''WesternAnimation/ForTheBirds'' also made a blink-and-you-missed-it cameo.
** The [[WesternAnimation/ToyStory Pizza Planet]] delivery truck appears in all of their films to date except ''WesternAnimation/TheIncredibles''. According to [[Creator/PixarRegulars Pixar regular Lee Unkrich]], there is actually no Pizza Planet in ''The Incredibles''.
** In the dentist's waiting room in ''WesternAnimation/FindingNemo'', you can see a Buzz Lightyear toy and a Mr. Incredible comic book.
* In ''WesternAnimation/BatmanUnderTheRedHood,'' [[MadScientistsBeautifulDaughter Talia]] is present at Jason's resurrection. She briefly looks ready to shoot him when he goes crazy, but beyond that gets no lines or characterization.

[[folder:Films -- Live-Action]]
* Johnny Fontane and (especially) Lucy Mancini in ''Film/TheGodfather''. In the novel they both get big storylines nearly the equal of the main storyline with Michael. In the film Johnny has a very small part and Lucy, basically one short scene confirming her as Sonny's mistress.
* The ''Film/XMenFilmSeries'' feature these in spades with minor characters (some of whom are only identified in the credits).
** Like with Beast making a hairless appearance in ''Film/X2XMenUnited'' and three of the Stepford Cuckoos appearing in the background during the third movie.
** The trucker who dropped Rogue off at Laughlin City was played by George Buza, who voiced Beast in the animated series.
** Even more subtle than a brief cameo, in the second movie the real names of several mutants, including Gambit, Scarlet Witch and Quicksilver, were briefly seen on a computer screen as being some of the prisoners in a mutant prison. Only three, Gambit, Banshee and Quicksilver, wound up appearing later (or rather, [[{{Prequel}} earlier]]) in ''Film/XMenOriginsWolverine'', ''Film/XMenFirstClass'' and ''Film/XMenDaysOfFuturePast''.
** [[HumongousMecha The Sentinel]] in ''Film/XMenTheLastStand''. Or rather, its head.
** In ''Film/XMenFirstClass'', Mystique tries to seduce Magneto. He tells her, "Maybe in a few years." She then shapeshifts to Rebecca Romijn, who plays her in [[Film/XMen1 the]] [[Film/X2XMenUnited original]] [[Film/XMenTheLastStand trilogy]].
** ''Film/TheWolverine'':
*** [[spoiler:Magneto and Xavier in the Stinger, which also shows an in-universe advertisement for Trask Industries for ''Film/XMenDaysOfFuturePast''.]]
*** [[spoiler:Also Wolverine's classic costume makes a brief appearance in the alternate ending. When Yukio and Logan board the plane, Yukio hands him a large flat box. He opens it to find himself staring at a familiar yellow face mask, with other spandex pieces. All he can do is give Yukio a "Really?" look.]]
* ''Film/SpiderManTrilogy'':
** The films use Dr. Connors a.k.a. the Lizard as a minor character. He did not become a villain, and until the ContinuityReboot (where he was the main villain), never got do so. Which is a shame as the actor who originally played Doc Connors has said he'd really like to take on that role.
** John Jameson, a.k.a "Man-Wolf" is seen in ''Film/SpiderMan2''.
* There are lots of tiny ones in the ''Film/LordOfTheRings'' films, some of which are blown up into full appearances in the extended versions.
* In ''Film/BatmanAndRobin'', the man who turns Pamela Isley into Poison Ivy is Jason Woodrue, who in the comics is the Floronic Man, an enemy of the Atom.
* ''Franchise/StarTrek'':
** In ''Film/StarTrekFirstContact'', the USS ''Bozeman'', the other ship in the GroundhogDayLoop episode "Cause and Effect", a time-displaced ship that was [[NoEnding never given any actual closure]], is a part of the Earth defense fleet.
** The ''Bozeman'' was also mentioned in ''Film/StarTrekGenerations'' -- it had to make a course correction due to the destruction of a star. And since Bozeman, Montana is Brannon Braga's hometown it's a RunningGag on that level too.
* ''Film/{{Troy}}'' features one that only Latin nerds are going to pick up on, in a nod to the Roman lovechild of the ''Literature/TheIliad'' and ''Literature/TheOdyssey'': ''Literature/TheAeneid'', which follows the Trojan survivors of the sack of Troy. At the end of the film, Paris hands off the sword of Troy to a young man who gives his name, when prompted, as "Aeneas". Paris tells him to find a new home for their people, which, presumably, film!Aeneas does, after seven years of gallivanting about.
* The deleted opening of ''Film/TheIncredibleHulk'' (2008) has a {{cameo}} appearance by ComicBook/CaptainAmerica, teasing at ''Film/CaptainAmericaTheFirstAvenger''. Blink and you'll miss it. Pause it ''just right'', and you might just make him out; but he is there, under the ice.
** Later disproven when the Captain America movie reveals that Cap was locked in the ice... inside a huge airship, which the Hulk movie doesn't show. This doesn't mean that the Hulk movie wasn't teasing, only that in retrospect we are forced to assume that was some other guy frozen in the ice.
* Speaking of ''Film/CaptainAmericaTheFirstAvenger'', there's a brief cameo where the [[UsefulNotes/TheGoldenAgeOfComicBooks Golden Age]] Human Torch can be seen at the science exhibit Steve and Bucky attend.
* ''Film/LandOfTheDead'' has Blades from ''Film/DawnOfTheDead1978'' reappearing when the zombies break into Fiddler's Green. Also it retroactively includes the main character from ''Film/SurvivalOfTheDead'' as one of the military guys at the check point.
* The third ''Literature/{{Silverwing}}'' book, ''Firewing'', features small appearances by both Goth's former toady Throbb and by the former Silverwing colony elder Frieda, both of whom are dead at that point.
* In the opening of Disney's ''Film/MaryPoppins'', Bert sings to Miss Lark with her dog Andrew, Mrs. Corry with her tall daughters, and Miss Persimmon. These are all supporting characters from the ''Literature/MaryPoppins'' books who were otherwise completely eliminated from the movie version.
* The ''Film/HarryPotter'' movies also have some of these which are only identifiable through the credits. For example, a tall, prim-looking woman with a pointed hat appears in the background of several scenes in the second film. The credits reveal that she is Madam Pince, the Hogwarts librarian in the books.
* The Duke brothers from the Eddie Murphy film ''Film/TradingPlaces'' appear in another Murphy film, ''Film/ComingToAmerica'', homeless and broke after their fall in the other film.
* Lana Lang and Steve Lombard are in ''Film/ManOfSteel'' but have smaller roles than others of Superman's supporting cast.
* ''Film/{{The Phantom|1996}}'' includes a number of passing references to continuity elements from the comics, including names on background signage and cameo characters (such as Corporal Weeks of the Jungle Patrol).

* ''Literature/{{Noob}}'' had a few passing mentions of Dark Avenger and one of Précieux, both of whom are recurring characters in the original webseries but have yet to play any kind of role in the novels.

[[folder:Live-Action TV]]
* A regular occurrence on PowerRangers as a series after Mighty Morphin'. There is almost always an episode that involves the show's starring team, needing to team-up with the previous series' team to take down a common enemy. For example, the "In Space" team had to team-up with the "Lost Galaxy" team.
* In an episode of ''Series/RippingYarns'', Creator/MichaelPalin's character storms out of his house in a black mood at the poor showing of his beloved football side. A passer-by watches, bemused. This unspoken cameo is very obviously Creator/JohnCleese in 1930's clothing not a million miles away from his [[Creator/MontyPython Gumby]] persona. All it needs is the knotted hanky and the rolled-up trouser legs... but the cloth cap screams Gumby.

* They appear by the truckload in ''Pinball/TheTwilightZone'', thanks to the license. A full list of references [[http://www.ipdb.org/rulesheets/2684/tz-tie-ins.htm can be found here]].

* Franchise/{{LEGO}} loves doing this. Just check out their animations and [[VideoGame/LEGOAdaptationGame video games]], and you will notice how frequently their ''Franchise/StarWars'' and ''Franchise/IndianaJones'' universes tend to collide. When talking strictly about the sets, fans are generally delighted to see older pieces reappear in other lines (usually in new colors or with new uses).

[[folder:Video Games]]
* ''VideoGame/MegaManBattleNetwork'' sort of is this. Turns out, this series is pretty much the others as an RPG. All of the characters return.
** Later on, they play it straight in the OneGameForThePriceOfTwo ''Battle Network 5: Team Colonel and Team Protoman''. When the team leaders are brainwashed by the big bad, the leader of the other team shows up to save them. If Colonel is brainwashed, Protoman comes to save him, and vice versa. When asked if they would join the cause, they say they have more important things to attend to.
** Also, scattered about the ''Battle Network'' series are references to the actual ''[[VideoGame/MegaManX X]]'' and ''[[VideoGame/MegaManLegends Legends]]'' series, not just the AlternateContinuity versions that show up as Net Navis. Servbot dolls, references to the Tron Bonne show, and badass posters of Vile and Zero at Hisgsby's shop are a few examples of this.
** What's more, Shaun/Sean, who was a fairly important character in the games but was committed from the Anime, is briefly seen in a crowd scene in the anime's movie.
* In the UsefulNotes/PlayStation version of ''VideoGame/MegaManX 3'', Volt Catfish's anime intro has a quick background cameo of Auto from the [[VideoGame/MegaMan Classic]] series.
* The ''VideoGame/TalesSeries'' often insert quite a bit of Namco cameos and {{Continuity Nod}}s. Probably the best part, however, is being able to battle the past heroes of the series, usually in the arena.
* Epona, the merchant elf from ''VisualNovel/TearsToTiara'' shows up at one point in ''VideoGame/TearsToTiara2''.
* ''Franchise/FinalFantasy'' started a tradition in ''VideoGame/FinalFantasyVIII'' of having GoldfishPoopGang boss Gilgamesh (of ''VideoGame/FinalFantasyV'' fame) appearing in other games in the series. Because of how he arrives in the game's universe and how he departed the plot in ''VideoGame/FinalFantasyV'', it can be safely assumed that he is the only cameo character that is canonically the same person. He even had some retcons in remakes to place him within ''VideoGame/FinalFantasyVI'' and the original ''VideoGame/{{Final Fantasy|I}}''. In ''VideoGame/FinalFantasyIX'', he goes by the name "Alleyway Jack" but eventually reveals Gilgamesh as his true name. His other appearances in the series imply that he is aware of the other games and their heroes and in ''VideoGame/FinalFantasyXII'', he comes with a pair of boss fights and wields replicas the defining weapons of many main characters in the series. He also has a dog named Enkidu that shows up in some of his appearances, but not all of them. He is often searching for the sword Excalibur, but frequently mistakes it with Excalipoor, and his attacks will often reflect this distinction - Excalibur is extremely powerful, whereas Excalipoor does 1HP of damage. His Summon in ''Dissidia'' reflects this, in that his summon will either triple the caster's BP or reduce it to 1. In ''VideoGame/FinalFantasyXIV'', Gilgamesh makes a recurring appearance in a series of endgame sidequests starring Hildibrand Manderville, and is fought twice in the questline as a boss.
* In ''Tony Hawk's Proving Ground'', [[SmugSnake Eric Sparrow]], the primary villain of the ''Tony Hawk's Underground'' sub-series reappears (though just as "Eric") in the Pro story path as an antagonist.
* ''VideoGame/FireEmblem: [[VideoGame/FireEmblemElibe Blazing Sword]]'' (the first game in the series released internationally), being a direct prequel to the previous game (the Japan-only ''Fire Emblem: The Binding Blade''), features several cameos from that game, most notably Prince Zephiel, who grows up to be ''The Binding Blade'''s BigBad. In fact, ''Blazing Sword'' appears to end on a cliffhanger to players unaware that the scene depicting Zephiel's StartOfDarkness was merely filling in the time gap between the two games.
** ''Fire Emblem: [[VideoGame/FireEmblemAkaneia Shadow Dragon]]'', the DS remake of ''The Dark Dragon and the Sword of Light'', features several cameos from the original game's sequel ''Mystery of the Emblem''.
* ''VideoGame/SuperMario64'' had a cameo for Yoshi, and you'd have to look for him, too, and would only get to where he is after you'd get all the stars.
* In ''VideoGame/PokemonDiamondAndPearl'', the Japanese games have continuity cameos for the anime characters Butler and Diane of the [[Anime/PokemonJirachiWishmaker sixth movie]] and Hitomi (Rebecca) of the [[Anime/PokemonDestinyDeoxys seventh movie]]. However the game's translation team missed this, instead [[InconsistentDub calling them Felix, Dana and Jamie]] respectively.
** In ''[[VideoGame/PokemonGoldAndSilver Heartgold and Soulsilver]]'', you can find Crasher Wake, one of the ''VideoGame/PokemonDiamondAndPearl'' gym leaders, in the Celadon City department store, and ''VideoGame/PokemonRubyAndSapphire'' champion Steven. He'll tell you about either Latias (Heartgold) or Latios (Soulsilver) roaming around. Then, after you beat [[spoiler:Red, the protagonist from the first games]], you can get one of the Hoenn starters from him, and also trade him a Forretress for his Beldum. And in ''Diamond, Pearl and Platinum'', you can also find Jasmine from ''Gold'' and ''Silver'' at the beach in Sunyshore City.
** Cynthia from Diamond/Pearl/Platinum does this twice. She's at the Ruins of Alph/Sinjoh ruins if you take Arceus there, and she's the BonusBoss in ''VideoGame/PokemonBlackAndWhite'' and [[Videogame/PokemonBlack2AndWhite2 their sequels]].
** ''[[VideoGame/PokemonRedAndBlue Pokemon Yellow]]'' had Team Rocket's Jessie and James as recurring bosses, along with Meowth (though he never speaks) and their Arbok and Weezing.
** Red and Blue from the first games both appear in Gold And Silver.
** Taken UpToEleven in the [=PWT=] in Videogame/PokemonBlack2AndWhite2, where ''every single gym leader from every region '''and''' their champion'' make a cameo. And yes, this counts [[spoiler:Red as well]].
* ''VideoGame/PokemonSuperMysteryDungeon'' goes crazy with this, having dozens of major and minor characters from every past game in the series (Even the obscure UsefulNotes/WiiWare titles) make appearances as recruitable team members and drop a line or two that makes it clear that they're the same individuals.
* The Mad Gear gang from ''VideoGame/FinalFight'' makes an appearance in Sodom's ending in the first ''VideoGame/StreetFighterAlpha'', as well as spectators on the background of Guy's home stage in ''Alpha 2'' and ''Alpha 3''. Rolento and Cody, who only had cameos in the first and second ''Alpha'' games respectively, both became playable fighters in the succeeding installments.
** A billboard promoting a wrestling match between Hugo (from ''2nd Impact'') and an unknown challenger can be seen on Cody's home stage in ''Alpha 3''.
** Balrog and Vega both appear in Sagat's endings in the first two ''Alpha'' games before they became playable characters in ''Alpha 3''.
* ''Franchise/MetalGear'':
** ''VideoGame/MetalGearGhostBabel'' is an alternate sequel to ''VideoGame/MetalGear'', and contains at least one main character based on a rejected concept for a main character in ''VideoGame/MetalGearSolid'', but Roy Campbell and Mei Ling both appear, and a reference is made to Raiden from ''VideoGame/MetalGearSolid2SonsOfLiberty'' ([[EarlyBirdCameo which hadn't been released at that time]]), along with Big Boss, Gray Fox, and Meryl Silverburgh.
** Teliko and Venus from ''VideoGame/MetalGearAcid'' and ''VideoGame/MetalGearAcid2'' both get small, story-irrelevant cameo roles as bonus recruitable characters in ''VideoGame/MetalGearSolidPortableOps''. They are both explicitly identified in-game as [[CanonImmigrant aliens from another dimension]].
** ''VideoGame/MetalGearAcid'' series:
*** Its [[FightLikeACardPlayer game mechanics]] run on this. While the game takes place in a completely separate continuity with no canon characters other than Solid Snake making a direct appearance and even Big Boss and Outer Heaven conspicuously absent from the backstory, the Character cards are all direct references to other ''Metal Gear'' games. Each of these cards plays a small cutscene of the original character who inspired it and while some simply provide useful effects with a bit of flavour text, others allow the player to directly use that character's abilities (for instance, the Psycho Mantis card allows the player to mind control guards, the Fortune card makes all bullets miss you, The Fury and Fire Trooper cards are the characters' flamethrowers...).
*** Snake's friendship with Roy Campbell is mentioned in the opening cutscene as the reason Snake was selected for the mission.
*** In ''VideoGame/MetalGearAcid2'', the BossRush mode allows the player to battle Liquid Snake, Revolver Ocelot, Vamp, Fortune, The Boss and The End in various permutations, as well as Teliko and a {{palleteswap}} Venus. All use adaptations of their original fighting styles using the cards from the card system and are fought in new arenas resembling Shadow Moses Island, the Big Shell and Tselionyarsk (all with the original Alert music from these games).
*** Unlockable cutscenes from ''VideoGame/MetalGearSolid3'' can be found in ''VideoGame/MetalGearAcid2''.
* The ''Franchise/BreathOfFire'' series is rife with cameos from previous installments, usually from the former main party. In some cases, the translator misses them and changes their names, obscuring the connection.
* In the intro to ''VideoGame/{{STALKER}}: Shadow of Chernobyl'', the unnamed character who "saves" (they are essentially selling them into indentured servitude) the player character in the introduction matches the description (notably, he is the only character with red hair in the entire game) of the character Redrick from ''Literature/RoadsidePicnic'', one of the game's main influences.
* ''VideoGame/{{Solatorobo}}'' features random cameos of Waffle Ryebread, Princess Terria, Cyan, and the Black Cats Gang from ''VideoGame/TailConcerto'', which it is a SpiritualSuccessor to. Mamoru and his father from ''[[http://www.anzen-fukuoka.jp/child/mamoru/index.html Mamoru-kun]]'' also make appearances.
* ''VideoGame/MarvelVsCapcom3'' and its update ''Ultimate Marvel vs. Capcom 3'' feature cameos from numerous Marvel and Capcom characters in the in-game endings. ComicBook/NickFury shows up in Crimson Viper's ending as a nod to the Franchise/MarvelCinematicUniverse, [[VideoGame/StarGladiator June Lin Milliam]] appears as a member of the new [[WestCoastTeam West Coast Avengers]], [[ComicBook/LukeCageHeroForHire Luke Cage]] and [[VideoGame/RivalSchools Batsu Ichimonji]] can be seen as part of the new Heroes For Hire, ComicBook/BlackPanther pops up, ect.
* In the ending of ''VideoGame/SuperRobotWarsUX'', [[spoiler: [[VisualNovel/{{Demonbane}} elder god Kurou and Al-Azif]]]] show up to watch over their [[spoiler: non elder god selves]] and talk about how they can leave [[VisualNovel/{{Demonbane}} Kuzaku]] to them (once again referencing [[VisualNovel/{{Demonbane}} Kishinhishou]]).
* In ''VideoGame/SuperSmashFlash2'':
** One of Fox's [[PaletteSwap alternate costumes]] is Marcus, his and Krystal's [[BabiesEverAfter future son]] from one of the endings of ''VideoGame/StarFoxCommand''.
** One of Ichigo's costumes is ogihcI, his [[EvilCounterpart hollow]] that he fought in ''Anime/{{Bleach}}''.
* After the introduction of Create-a-Character Mode in the ''VideoGame/SoulSeries'', this became a common occurrence:
** Li Long and Hwang were main characters from Soul Edge that were eventually dropped in ''[=SoulCalibur=]'' and ''[=SoulCalibur=] II'' respectively, having been replaced by Maxi and Yun-seong. While they did make a pseudo-return in ''[=SoulCalibur=] III'' representing two of the generic but unique "Create-a-Character" styles (and were later upgraded to full characters in the ''Arcade Edition''), both would revert back to this in subsequent games, appearing as simple "Create-a-Character" CPU opponents using Maxi and Yun's styles one can fight in the single player modes of ''[=SoulCalibur=]: Broken Destiny'' and ''[=SoulCalibur=] V''.
** Arthur, the British-born samurai once used to replace Mitsurugi in certain overseas versions of the ''[=SoulCalibur=]'' arcade, made a similar return to Hwang and Li Long in ''[=SoulCalibur=] III'' (although he didn't got into ''Arcade Edition''), and would also appear as a "Create-a-Character" CPU opponent in later games.
** Besides the three mentioned above, ''Broken Destiny'' included a number of Create-a-Character cameos from the backstory one can fight in "Quick Match". Some of these include Xianghua's father, Siegfried's friend Salia, Greed and Miser.
** Kilik's master and DittoFighter Edge Master from ''[=SoulCalibur=]'' made an uncredited cameo in ''[=SoulCalibur=] III'' as a secret challenger entirely obscured by shadows (he appears as a sillhouette, basically) named "Shadow Master", meant to represent his SuperpoweredEvilSide as described in Kilik's prologue.
* Arana and Kubira, characters from the ''Anime/{{Strider}}'' manga, appear as generic enemy grunts in some stages from the NES ''Strider''.
** [[AllThereInTheManual Officially]], the large automatic weapon used by a few Russian soldiers in the original Arcade ''Strider'' is meant to be a "Shadowtag Bullets", a weapon featured during the final chapters of the manga.

[[folder:Visual Novels]]
* From the ''VisualNovel/ToHeart'' series:
** In the final episode of ''To Heart: Remember My Memories'', Sango Himeyuri from ''VisualNovel/ToHeart2'' makes a cameo by submitting what is presumably [[spoiler:HMX-17 Ilfa's operating system]] to Nagase in person. Her sister Ruri Himeyuri calls her in the background, saying that they're gonna be late for a movie. The episode [[EarlyBirdCameo aired]] '''[[EarlyBirdCameo three days]]''' [[EarlyBirdCameo before]] the entire ''To Heart 2'' franchise began with the release of the [=PS2=] game.
** Additionally, Konomi Yuzuhara, also from ''To Heart 2'', makes a cameo in the sixth {{omake}} of ''Remember My Memories'' as Akari's opponent. The match results were never revealed though.
** The ''To Heart 2'' GaidenGame ''Another Days'' returned the favor by sneaking Multi and Serio [[http://img380.imageshack.us/img380/1561/burgerstand1bs6.jpg in a background]] (look on the left); apparently, by that time in the ''To Heart'' universe, their obsolescence reduced them to working at fast food restaurants.

[[folder:Web Comics]]
* In ''Series/{{DHS Comix}}'', in Random Encounter, various important characters in the world's history appear as portraits across Dhark's Hero School. This includes portraits of Deimi and Dyaris, Lavendar, as well as the founders of Dhark's, most notably being the painting of them in Mana's office.
** Malo, Demi, and Carla from "Free Turn" briefly appear in Volume 35 of "Random Encounter" as attendants of the Monster Races. Miss E. also appears with a stall set up in the same volume.
** Miss E. also appears briefly "Loose Change" during Silphy's explanation of Underground tattoos.
** Daren Marks appears as a member of the convoy in "The Breaking" after his appearance in "Daisy", being a subsequent explanation to his absence in "Peony"

[[folder:Web Original]]
* Many characters were introduced in the novel adaptation of ''Series/{{Noob}}'', but didn't show up in the webseries version before the movie was made. Some of the characters that got their first live-action appearance in the movie had been mentionned by name in the webseries beforehand.
* {{WebVideo/RockedReviews}} has been known to include several cameos of other internet reviewers in his ''Regretting The Past'' series. Most of these reviewers also contribute to channel awesome. For example, TheNostalgiaCritic makes cameos in the RTP on Nickelback's ''All The Right Reasons'' to force him to review the album's third track ''Photograph.''

[[folder:Western Animation]]
* The '90s ''WesternAnimation/XMen'' cartoon was full of these.
** Ranging from well-known comic characters displayed prominently, such as Morph (himself based on long-unseen comics character Changeling) changing into SelfDemonstrating/{{Deadpool}} to fight ComicBook/{{Wolverine}}, or ComicBook/WarMachine and ComicBook/NickFury watching a broadcast together on the Hellacarrier. Others are more obscure like Beast wearing a ComicBook/HowardTheDuck T-shirt or [[ComicBook/XForce Domino]] appearing on a TV in the background.
** Probably the best episode for cameos was "One Manís Worth". A BadFuture episode that inspired ''ComicBook/AgeOfApocalypse'', it featured cameos from characters such as Comicbook/IronMan, Blink, Mimic, Holocaust, Frenzy, ComicBook/CaptainAmerica, ComicBook/TheWasp, Comicbook/BlackWidow, [[ComicBook/TheMightyThor Thor]], Comicbook/ScarletSpider, [[ComicBook/TheIncredibleHercules Hercules]], and [[ComicBook/AntMan Goliath]].
* ''WesternAnimation/FantasticFour'' was also notable for the sheer number of superhero cameos, ranging from Rage and Comicbook/TheAvengers to Scarlet Spider and the ComicBook/NewWarriors.
* Franchise/{{DCAU}}:
** In the first ''WesternAnimation/JusticeLeague'' season finale "The Savage Time," young versions of Dick Grayson and Barbara Gordon (making out), as well as Tim Drake and [[Comicbook/{{Batgirl 2000}} Cassandra Cain]] showed up in uncredited cameos in Batman's LaResistance in [[SetRightWhatOnceWentWrong a dystopian timeline]].
** Puppy-[[GratuitousAnimalSidekick Krypto]] in [[WesternAnimation/SupermanTheAnimatedSeries "Last Son of Krypton."]]
** During the GreenLantern episode of ''WesternAnimation/SupermanTheAnimatedSeries'' featured Kyle Rayner as the Green Lantern, but Hal Jordan's name appearing on the side of an aircraft. In the same episode, Guy Gardner (the Green Lantern before John Stewart) cameos as a mugger that gets beaten up by Kyle.
** Hal's actual appearance is also of this variety, replacing John Stewart for a couple minutes due to time travel-related ripple effects. He's up to speed as to what's going on, picks up where John left off, and John shows right back up.
* The second season finale of ''WesternAnimation/{{WITCH}}'' had a scene where it shows a man in a car named Scylla looking at the "cartoon" [[WeirdnessCensor the finale battle looked like to everyone]], and the last scene was the girls being introduced to him as their new teacher. This was originally supposed to be a ChekhovsGunman as he was a character from the next arc of the comics, but was reduced to this as the animated series wasn't renewed for another season.
* The [[FiveEpisodePilot Three-Episode Premiere]] of ''WesternAnimation/TransformersAnimated'' has Spike, Carly, and Daniel -- that is, the original human protagonist from Generation 1, his love interest, and their son -- as prominent background characters. They all show up again later with speaking roles, albeit the parents separately from Daniel.
** Then you see Sparkplug, Spike's dad, working on a construction site with the trademark hardhat on two separate occasions.
** One WholeEpisodeFlashback showed Sentinel talking to red bot that looks a lot like (and [[WordOfGod Derrick Wyatt has confirm is supposed to be]]) Cliffjumper. They have stated that he was originally that one that [[spoiler:Shockwave would frame for being a spy]], but ExecutiveMeddling ruled against it. He actually reappears later as a RecurringCharacter in season three, and even speaks!
** We also see Mainframe operating a computer in a scene during the season three premiere. Like the Action Master he's based on, he doesn't transform.
** A rather large example are the bust of the [[http://tfwiki.net/wiki/Cyber-Ninja_Corps Cyber-Ninja Corps]] that appear in "Five Servos of Doom", which includes so many that Derrick Wyatt had to say what half of them were on Twitter ([[http://tfwiki.net/wiki/Five_Servos_of_Doom#Notes details on this page]]).
** Yet another example: In "Human Error, Part 1" we see Cancer and Hydra from ''Anime/TransformersSuperGodMasterforce'' sitting at a table [[CreatorCameo with series story editor Marty Isenberg.]]
** The ultimate fate of [[spoiler: Blackarachnia and Waspinator?]] Transwarped to a primitive world, where the first things they meet are a gorilla, a cheetah, a rhino, and an oversized rat. [[WesternAnimation/BeastWars Hmmm...]]
** It's bigger than all of that: every single Transformer seen in the series (including crowd-scene extras and portraits on the menu at restaurants) is a version of a character from a previous franchise, including production glitches and Brazil-only knockoffs; see the Transformers wiki for details. Heck, the producers have even said that one of the humans' limos was actually a character from ''Go-Bots''.
* The ''WesternAnimation/BatmanTheBraveAndTheBold'' episode "Day of the Dark Knight" begins with a prison break at Iron Heights; among the escapees are numerous [[Series/{{Batman}} Adam West Batman]] villains including King Tut, Egghead, the Bookworm and Louie the Lilac among others. In addition, the Clock King's face is revealed in the same episode to be modeled after Walter Slezak, his actor in the 1960's series.
** King Tut actually shows up in a later BatmanColdOpen so it changed him from this to the CanonImmigrant.
** Several episodes feature a bar populated by D-list supervillains. It's almost impossible to name every baddie who makes an appearance there without consulting Wikipedia.
** ComicBook/FlexMentallo and Dorothy Spinner appear on circus posters in "The Last Patrol".
* ''WesternAnimation/LegionOfSuperHeroes'' has a few:
** ComicBook/BoosterGold and Skeets are cleaning the Superman Museum.
** A dead ringer for Lobo gets his hoverbike stolen.
** A whole mob of Franchise/{{Superman}}'s Phantom Zone villains shows up, but they don't say a word or even do anything but be mysterious and threatening. Though one of them (General Zod) threatens the Legionnaires trapped in the Zone, and he appears to share the same voice as the one in Drax's head.
** Legionnaires that never get a speaking role still appear on viewscreens during member induction ceremonies or in the gigantic SeasonFinale battles.
* Several characters from ''Disney/{{Aladdin}}: the Series'' could be seen as guests at Aladdin and Jasmine's wedding in ''Aladdin and the King of Thieves''.
* Ankama does this to the point of notoriety in ''WesternAnimation/{{Wakfu}}'', an animation taking place in the same universe as the MMORPG of the same name and its predecessor, ''VideoGame/{{Dofus}}''. Many characters and creatures from the ''VideoGame/{{Dofus}}'' game and comics make appearances, be them as background flavour or as full secondary characters.
* WesternAnimation/DuckDodgers did a crossover with the characters of GreenLantern once. Several GL characters have significant roles (Sinestro, Hal Jordan, Katma Tui, Ch'p, Killowog), but the initial battle between the Corps and the robots also contains quite a few Blink-And-You'll-Miss-It appearances from characters only readers of the comics would recognize. Examples include Salaak, Boodika, Tomar Re, and Guy Gardner.
* In the American ''WesternAnimation/StreetFighter'' animated series, the new characters from the first ''VideoGame/StreetFighterAlpha'' game appears as participants in an underground fighting tournament (namely Adon, Birdie, Guy, Sodom, Rose and a weird rendition of Dan in his Player 2 colors) in the episode "The Medium is the Message". Everyone except Dan and Adon went on to have focus episodes in Season 2. Notably absent in the tournament was Charlie. This is because the cartoon followed the decision of [[CompositeCharacter making Blanka and Charlie into the same character]] and instead he gets a flashback of when he used to be Charlie (wearing the same clothes as his Alpha self) before mutating into Blanka.
** In the same episode, the cast of ''VideoGame/FinalFight'' can be seen among the crowd, including Carlos and Maki from the SNES sequel. ''VideoGame/FinalFight'' would get its own episode in Season 2.
** In "Keeping the Peace", Guile's opponent in the first scene is Bred, also from ''VideoGame/FinalFight''.
* ''WesternAnimation/MickeyDonaldGoofyTheThreeMusketeers'' opens with the trio being saved by the [[Literature/TheThreeMusketeers original musketeers]], who gives Mickey his NiceHat and autographs it.
* The design for the businessmen from ''WesternAnimation/AdventureTime'' is very similar to a businessman costume that an adventurer wore in an episode of ''WEsternAnimation/TheMarvelousMisadventuresOfFlapjack''. Also, the adventurer costume that the businessman wore in the Flapjack episode greatly resembles Billy from Adventure Time if he were human. Considering Creator/PendletonWard storyboarded the Flapjack episode, it makes sense.
* In ''WesternAnimation/TheProblemSolverz'', the dog from the original ''Problem Solvers'' Website/YouTube videos makes background appearances in some episodes.
* In ''WesternAnimation/{{ThunderCats|2011}}'' (2011), there are a few cameos from [[WesternAnimation/ThunderCats the original]].
** Fans will immediately recognize Lynx-O as the tower sentry who alerts Thundera to the {{Lizard|Folk}} invasion force.
** In "Legacy", ''WesternAnimation/SilverHawks'' BigBad Mon*Star and a race of ''[[WesternAnimation/TheComicStrip TigerSharks]]'' appear in {{flashback}}, as a form of CanonWelding.
** One of the background figures in the town during "The Duelist and the Drifter" wears a samurai helmet, as a nod to the original series' Hachiman. Whether it ''is'' Hachiman is a coin toss.
** Not to mention that Lion-O's father, King Claudius, was voiced by the same voice actor who voiced the original Lion-O from the '80s.
* In ''WesternAnimation/TeenTitans'' the fifth season basically made up of these, especially towards the end with people like Argent, Jericho and even two instances of ComicBook/WonderGirl making an appearance.
* ''WesternAnimation/YoungJustice'' is full of these. Various DC heroes like [[ComicBook/KingdomCome Magog]], [[Comicbook/{{Batgirl 2009}} Stephanie Brown]], and ComicBook/BlueDevil make cameo appearances throughout the show, and a few of these (Barbara Gordon, Bumblebee, and Mal Duncan) ended up becoming cases of ChekhovsGunman and [[EarlyBirdCameo Early-Bird Cameos]].
** In this version, [[{{Animorphism}} Beast Boy]]'s birth mom, Marie Logan, is a former actress, making her a CompositeCharacter with Rita Farr from the comics; however, Rita herself is briefly referenced as Marie's old co-star.
* ''WesternAnimation/BewareTheBatman'' featured an appearance by Michael Holt as a hostage and victim of Professor Pyg and Mister Toad. In the comics, he has a much larger role as the superhero Mister Terrific.
** Despite the show not using many famous Batman villains, the Penguin makes a cameo in a wanted poster, as Harvey Dent and the Special Crimes Unit briefly speculate whether he's even human. Penguin is also mentioned in a newspaper headline and in a news ticker.
