A Bootstrapped Leitmotif is born when a piece of BackgroundMusic becomes tied to a character, place, or other specific part of the story that it was not originally intended to represent.

This is often because the song in question is played during scenes that focus heavily on a specific character. In video games, this commonly occurs with music for stages or levels strongly associated with a certain character, or the character's BossBattle music. Sometimes a character may already ''have'' a {{Leitmotif}}, but a different song that is more readily identified by the audience usurps it and becomes more widely accepted and recognized.

A SisterTrope of BootstrappedTheme, where a leitmotif or other piece of music comes to stand for the series as a whole.

[[folder:Anime and Manga]]
* In ''Anime/LegendOfGalacticHeroes'' the use of Mahler's Sixth Symphony, first movement has become associated in the minds of fans with character Oskar von Reuenthal.
* ''Anime/DragonBallZ'' applies for the original and English versions:
** Original version: [[http://www.youtube.com/watch?v=A7bkURxX15s&feature=related Majin Buu's theme]]. It's actually the Super Saiyan theme variation for the Majin Buu saga (both the Freezer and Cell sagas have each its own variation of the theme), but it appears so many times during the Majin Buu saga as a BattleThemeMusic that it ended up associated with him instead of with the good guys. It's difficult to find anyone who doesn't think of Majin Buu when hearing it.
*** To a lesser extent, [[http://www.youtube.com/watch?v=9OYC4ScZeic&feature=related Freezer]] and [[http://www.youtube.com/watch?v=X-gUfx5QEmA&feature=related Cell]]'s themes also apply. These are better in the sense that, at least, they're exclusive to that saga, but still fit here because they're not exclusive to Freezer and Cell respectively.
*** The Saiyans' theme ended up being [[http://www.youtube.com/watch?v=_ZMQObv7VEw&feature=related Vegeta's theme]], because he's by far the most important of the (evil) Saiyans, and the only one who survives. Although it appears whenever one of the evil Saiyans is on screen (it first appears with Raditz), after Raditz and Nappa die it can only appear with Vegeta on screen. It doesn't help that it's used much after than even the Namek saga (this tropes remembers hearing it during at least during the Androids saga, when Vegeta appears to save Goku from Android 19).
*** Pretty much all the ''Anime/DragonBallZ'' characters' leitmotifs (except [[http://www.youtube.com/watch?v=DMPvHtWTdYM Gohan]] and [[http://www.youtube.com/watch?v=ONyGzRnJyHI&feature=related Piccolo]], who have an official leitmotif) fall into this trope. [[http://www.youtube.com/watch?v=0-rqq5u78Xs&feature=related Broly]] and [[http://www.youtube.com/watch?v=yZjoUPgZA4M&feature=related Cooler]] also have an unofficial leitmotif.
** English dub: [[http://www.youtube.com/watch?v=mVf8007iFUg Gohan's Super Saiyan theme]]. It's actually the Hyperbolic Time Chamber theme, as the first comment says, but everyone knows it either as "Gohan's Super Saiyan theme" or "Gohan's Super Saiyan 2 theme", because of the 5 seconds or so that can be heard when Gohan transforms to [=SSJ2=] for the first time. It doesn't help the fact that Gohan doesn't have an official Super Saiyan theme.
** English dub again: Inverted with [[http://www.youtube.com/watch?v=Es9Fk6v5n-0 Ginyu Transformation]]. Introduced for Captain Ginyu's body-switching ability, it ended up being used for generally "epic" moments (Super Perfect Cell's death, Kid Buu blowing up Earth) long after Ginyu's death - all without changing its name.
* Franky in ''Manga/OnePiece'' got this with the third part of a soundtrack tune called "[[http://www.youtube.com/watch?v=xI15eWz8Wec Serious Games]]." The only other previous use in the series had been for one of Usopp's [[CrowningMomentOfAwesome Crowning Moments of Awesome]]. It is now heard regularly when Franky does anything and on his eyecatches.
* Susumu Hirasawa's "Forces," due both to its use during Guts' first battle with the Hawks and its use in the "next episode" trailers, has come to be considered the main theme of ''{{Berserk}}''.
* [[https://www.youtube.com/watch?v=NPL47bmUhXo Kimi wa Dare o Mamotte Iru]] is this for the title character of ''Manga/RurouniKenshin'', given that [[https://www.youtube.com/watch?v=Iw1uoGrgA8E&list=PLF041573F16517029&index=4 his official theme]] (the aptly-titled "Himura Kenshin Theme") is far less remembered and the former is usually the first thing people hear when they think of the character and the show itself.
[[/folder]]

[[folder:Film]]
* Jason's theme from the ''Franchise/FridayThe13th'' movies (you know the one - ''ki-ki-ki-ki/ma-ma-ma-ma'') was originally [[spoiler: his mother's theme from [[Film/FridayThe13th1980 the original movie]], in which Jason didn't even appear. It was derived from her Jason personality telling her to kill Alice ("Kill her, Mommy!")]] It only became his theme in [[Film/FridayThe13thPart2 the next movie]].
* Franchise/{{Godzilla}} has two main themes: the slow, dark "horror" theme from the [[Film/{{Gojira}} original movie]] when he rampages through Tokyo, and also from the original movie, the up-tempo Self Defense Forces march, which become so associated with the monster that even the composer began calling it Godzilla's Theme. Nowadays, both are used relatively equally, depending on what kind of mood is being called for.
* "Hooray For Captain Spaulding" from ''Theatre/AnimalCrackers'' became [[MarxBrothers Groucho Marx]]'s theme song in this manner (most explicitly as the theme to ''Series/YouBetYourLife'').
* This is more of an in-development bootstrap, but in ''Film/TheLordOfTheRings'' you first get glimpses of the Gondor and Minas Tirith themes in ''The Fellowship of the Ring'', but once it comes their time to shine in ''Return of the King'', they've changed meaning: since there isn't that much of a distinction between Gondor and Minas Tirith, the Gondor theme is used for both, while the Minas Tirith theme seems to be used for Isildur's heritage (the line of kings and, most prominently, the sword Andúril).
[[/folder]]

[[folder:Live Action TV]]
* On ''Series/ArrestedDevelopment'', the "Oscar is Buster's real father" theme became the general theme for Oscar and I'm Oscar Dot Com.
* ''Series/StarTrekTheOriginalSeries'': The episode "[[Recap/StarTrekS2E1AmokTime Amok Time]]" had a leitmotif for the Vulcan traditions driving the episode, including the ritual fight between Kirk and an enraged Spock. The fight scene version was reused out of context during fight scenes in several other episodes that had nothing to do with the planet Vulcan, and the "Star Trek fight music" became one of the most-remembered (and most-parodied) aspects of the series as a whole.
[[/folder]]

[[folder:Professional Wrestling]]
* Linda [=McMahon's=] entrance theme began life as the theme for {{WrestleMania}}s X to XIV.
** On a related note, VinceMcMahon's theme, "No Chance in Hell", originally began as the theme to the 1999 Royal Rumble.
* Diabolic Khaos's theme, DimmuBorgir's ''Hybrid Stigmata- The Apostasy'', became the theme of [[Wrestling/HunterJohnston Delirious]] with the team getting a new theme song and every other member getting their own individual theme.
[[/folder]]

[[folder:Video Games]]
* Arguably the most famous case in the medium is Link. Link was never given a {{Leitmotif}} in the first games, despite almost every other character getting one. However, ever since ''VideoGame/TheLegendOfZeldaTheWindWaker'', the original game's title/overworld theme appears to have become Link's motif as well, being a case of BOTH a BootstrappedTheme (as the Main Theme of the series) AND a BootstrappedLeitmotif.
** It [[ThemeTuneCameo shows up again]] as the [[spoiler: "Song of the Hero"]], practically canon-izing its status as this trope.
** In another case, ''[[VideoGame/TheLegendOfZeldaTheWindWaker The Wind Waker]]'' uses the Hyrule Castle theme from ''[[VideoGame/TheLegendOfZeldaALinkToThePast A Link to the Past]]'' as [[spoiler:Daphnes Nohansen Hyrule]]'s leitmotif.
** The theme most commonly known as Zelda's Lullaby originated in ''[[VideoGame/TheLegendOfZeldaALinkToThePast A Link to the Past]]'' as the song played when rescuing one of the Maidens. It returned as Zelda's {{Leitmotif}} in ''[[VideoGame/TheLegendOfZeldaOcarinaOfTime Ocarina of Time]]'' & has being associated with her ever since.
* The stage music themes in ''VideoGame/StreetFighterII''. They ended up being the themes of the characters who uses it as their home stage.
* Funny that [[VideoGame/StarFox Fox McCloud]] never got ''his'' own theme, yet his rival Wolf has a personal theme. It is usually attributed to Fox that Area 6 in ''Star Fox 64'' is his theme, as it was used in ''VideoGame/StarFoxCommand''.
** It could be argued that Sector Z serves as the most iconic music for Fox - it was even used throughout Starfox Adventures when Fox was due to appear on screen.
** In ''SuperSmashBrosBrawl'', Fox gets "Space Armada" from ''StarFox'' as his leitmotif in the Subspace Emissary, and "Main Theme (Star Fox)" as his Classic Mode credits music. "Area 6" is in the game, but is instead used as ''Falco's'' unlocking battle theme. Likewise, "Main Theme (Star Fox 64)" (i.e. the Sector Z theme) is used for Falco's Classic Mode credits theme.
** The original ''VideoGame/StarFox'' Corneria theme is also very popular, though it took ''VideoGame/SuperSmashBros'' three games to finally implement the theme into ''Brawl[='s=]'' soundtrack.
* A slowed down version of the Pollyanna theme was used as Ness' [[http://www.youtube.com/watch?v=JcoFILRmugQ house music]] in ''VideoGame/EarthBound''. Not entirely recognizable at first, though. While not his official leitmotif, it's frequently associated with him.
* In ''VideoGame/FinalFantasyV'', this happens ''within the game itself'' to Gilgamesh. The first time you fight him, it plays the regular boss music. The second time you fight him it is during the Big Bridge segment, throughout which the appropriately named "Battle at the Big Bridge" plays. However, it becomes Gilgamesh's own theme as it plays during battles with him later in the game which do not even take place on the Big Bridge. The theme has even followed him into other games in which he appears.
* In ''VideoGame/FinalFantasyVII'' "[[http://www.youtube.com/watch?v=3rV40ypje7o Those Chosen By the Planet]]" is Sephiroth's {{leitmotif}}. However, his battle tune, "[[http://www.youtube.com/watch?v=t7wJ8pE2qKU One Winged Angel]]", has mutated into his tune in the minds of the fandom and, as a consequence, in the compilation.
** "One-Winged Angel" does incorporate "Those Chosen By the Planet" though, so it's not so much a completely different {{Leitmotif}} as it is a BossRemix that became more popular than the original song it remixed.
** Also, Cloud was never attributed a specific theme, so he appropriated the game's [[http://www.youtube.com/watch?v=qFs8-qGaoHU Overworld theme]] and Main Theme as his own. It roughly follows his character growth throughout the game, variations of it are used during moments of powerful emotion for Cloud, and it coincidentally disappears from the Overworld at the same time Cloud leaves the party, to be replaced with the Meteor theme. It's no coincidence that it plays again in the Compilation over the credits of ''Crisis Core'', to indicate that Zack's torch has been passed to Cloud.
* ''VideoGame/FireEmblemTellius'' got the theme "''Eternal Bond''" as the Greil Mercenaries' charging theme, but in SuperSmashBrosBrawl it was renamed "''Ike's Theme''", and now is remembered as such. To be fair, VideoGame/FireEmblemTellius did use it in a character {{Leitmotif}} fashion in several scenes.
* The song called [[http://www.youtube.com/watch?v=D3RiF2r3vTY "Theme of Samus Aran: Galactic Warrior"]] in ''[[VideoGame/{{Metroid}} Super Metroid]]'' originally, is now probably better known as the music for Upper Crateria. Instead, the [[http://www.youtube.com/watch?v=mMvKDRCBQBM main theme of Super Metroid itself]] has since mutated into Samus' own character theme. [[http://www.youtube.com/watch?v=AHmGBQiSTv0 This video]] gives a good background on the history of the song.
** The Lower Crateria theme had a similar fate. The first time it cues in the game is when Samus returns from her brief visit to Brinstar and is suddenly faced with Space Pirates that weren't there before. Thanks to this, as well as remixes in ''Zero Mission'' and ''Corruption'', the theme is now associated with Space Pirate bases in general.
** ''Super Metroid'' used three different songs for its various boss fights. The one that played during both escape sequences, as well as the fights with Ridley, Draygon, and the Torizo, has come to be almost exclusively associated with Ridley and has been remixed for every appearance he has made in the series since. Even ''VideoGame/MetroidPrime'' and ''VideoGame/SuperSmashBros Brawl'' refer to it as "Vs. Ridley".
** The second boss theme, played during the Kraid, Crocomire, and Phantoon fights, has essentially become Kraid's theme, though this is more an unintentional example, since Kraid was the only one of the three to ever show up in another game [[spoiler:until Phantoon's BonusBoss appearance in ''VideoGame/MetroidOtherM'' - and even then, he just reuses the Metroid Queen's boss music]].
* In ''VideoGame/SuperSmashBrosBrawl'', while there are close to 250 distinct stage themes available, each character has one specific stage theme that always plays over the credits after beating Classic Mode. Each unlockable character also has a specific theme that plays during the fight to unlock them. Sometimes these are the same ([[Franchise/SuperMarioBros Luigi]] gets "''[[VideoGame/LuigisMansion Luigi's Mansion]]'' Theme" for both), and sometimes they are different ([[Franchise/TheLegendOfZelda Ganondorf]] gets "Gerudo Valley" from ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' for his credits music and "Hidden Mountain & Forest" from ''[[VideoGame/TheLegendOfZeldaALinkToThePast The Legend of Zelda: A Link to the Past]]'' for his unlocking match). In most cases, however, these tracks are more relevant to the ''games'' the characters came from than the characters themselves.
** Many characters acquire other Bootstrapped Leitmotifs in the cutscenes of the Subspace Emissary, the platformer-style adventure mode of the game.
** R.O.B. doesn't even get this justification: While his credits music is the theme from a R.O.B.-compatible game, ''Gyromite'', his unlock music is bizarrely the theme from ''[[VideoGame/MarioBros Mario Bros.]]'', likely the most egregious example of this trope from ''Brawl''.
** [[Franchise/SuperMarioBros Bowser]] is a unique example: his credits music is the "Giga Bowser" theme from ''[[SuperSmashBrosMelee Super Smash Bros. Melee]]'', which had never been applied to the standard form of the character before. Arguable since Giga Bowser is playable in this game as Bowser's [[LimitBreak Final Smash]].
** Averted with the handful of characters that have proper leitmotifs that predate this game, like [[{{Kirby}} King Dedede]] ("King Dedede's Theme") and [[StarFox Wolf]] ("Star Wolf"). They keep those pre-existing leitmotifs. Those characters with Bootstrapped Leitmotifs from other games keep them in some situations, but not all. (For example, [[VideoGame/{{Metroid}} Samus]] and [[FireEmblem Ike]] keep theirs in the Subspace Emissary, but not in the credits.)
* The composers of the ''{{Halo}}'' soundtracks said that they didn't intend to apply leitmotifs, but many music pieces can be bootstrapped to characters or locations, eg "Enough Dead Heroes" = Cortana, "Shadows" and "Devils...Monsters" = the Flood, "The Last Spartan" = Master Chief, "Weight of Failure" = the Arbiter (and later the Separatists), "Destroyer's Invocation" = Tartarus, "High Charity" = the Prophets, "Penance" = Delta Halo, "Earth City" = the Scarab, "Under Cover of Night" = Sgt. Johnson(his death scene uses a DarkReprise of it), "In Amber Clad" = Cmdr. Keyes, "Farthest Outpost" = the Ark.
** "Orbital Drop Shock Trooper" = the ODST team, "The Battle Begins" = Battle for Reach, "Noble Mission" = Noble Team, "Lone Wolf"/"Noble Six" = Noble Six, "Follow Our Brothers" = Elite Seperatists, "Ashes" = Kat/New Alexandria, "Make It Count" = Jorge, "Finish the Fight" = the Portal, "Sword Control" = Sword Base, "Rain"/"The Rookie" = The Rookie, etc.
* Several songs in the ''Franchise/{{Castlevania}}'' series have become recurring themes for the characters that starred in the games where they debuted. ''VideoGame/CastlevaniaRondoOfBlood'' has "Bloodlines" (the first stage theme) and "Slash" (the theme of one of the alternate stages), which have become respectively associated with Richter and Maria. "An Empty Tome" from ''VideoGame/CastlevaniaOrderOfEcclesia'', the song that plays when you first enter the castle, is repeatedly used as Shanoa's theme. "Iron Blue Intention" from ''VideoGame/CastlevaniaBloodlines'' has apparently been assigned as the theme for the Lecarde Family; the extended portion added for ''VideoGame/CastlevaniaPortraitOfRuin'' starts playing in the ending credits when Stella and Loretta's portraits appear on screen, and the original portion of the theme was used remixed for Eric's theme in ''[[VideoGame/CastlevaniaJudgment Judgment]]''.
** Both an Empty Tome mentioned above, and "Tragic Prince/Pitiful Scion" may have been intentional. "An Empty Tome" is used in the intro and in the castle's first area, yet the title describes Shanoa. "Tragic Prince/Pitiful Scion" also accurately describe Alucard, however, instead of being the first area/opening's theme, it's used in the Clock Tower, the one area that recurs in every game and to people that played the previous games can result in SoundtrackDissonance. The fact that the first area becomes a BootstrappedLeitmotif is probably [[LampshadeHanging Lampshaded]] by both ''VideoGame/CastlevaniaHarmonyOfDissonance'' and ''VideoGame/CastlevaniaAriaOfSorrow''. In the former, the first area is explicitly stated to be the protagonist Juste's theme in the sound test, and in the latter's extra mode where you play as Julius, the theme of the game's first area is replaced by his theme (which can also be considered this trope as it was two songs from previous games repurposed and popularized as his theme.)
** Alucard also has Dracula's Castle, as it was the [[Level1MusicRepresents opening area.]]
* In the ''VideoGame/{{Ys}}'' series, "Theme of Adol" and its variations is implied to be the titular hero's leitmotif, although it never seems to be directly connected with him in-game.
* ''Franchise/AceAttorney:''
** The second game, ''[[VisualNovel/PhoenixWrightAceAttorney Justice For All]]'', has a track called "Search - In the Midst 2002". While not technically considered a character theme, every instance of the song is connected to the defendant of the case it appears in, Matt Engarde, so is is any wonder that it is generally considered to be his theme?
** The DarkReprise, "Search - Core 2002", [[spoiler:is first played when he shows his true colors, so it again gets this treatment and is considered the "Evil!Matt Engarde Theme"]] Oddly enough, the same track ends up ''inverting'' this trope in the following game. While it was practically a Leitmotif in JFA, it becomes a general 'dark secret' theme in Trials and Tribulations.
** In the same case, when Miles Edgeworth finally returns, the theme "Great Revival" plays many of the times he is on screen, along with other non-Edgeworth-y events, such as [[spoiler:Franziska von Karma arriving with evidence]]. Jump ahead 7 years, and Great Revival is remixed into numerous themes of [[VisualNovel/AceAttorneyInvestigations Edgeworth's spinoff game]], including the Objection theme and end credits, essentially cementing itself as Edgeworth's Leitmotif. It gets remixed again in the second Edgeworth game.
** There's also Pursuit -- Cornered! which many consider Phoenix's theme, while other people consider as both his AND Edgeworth's theme. He has a theme proper in Objection! 2001 but Cornered appears in a flashback with both Phoenix and Edgeworth and was also used in the final moment of Phoenix' trilogy, while Objection! 2001 only appeared in the first game. It got to the point that upon his appearance in [[VideoGame/MarvelVsCapcom3 Ultimate Marvel Vs Capcom 3]] he is the only character with TWO themes, his [[http://www.youtube.com/watch?v=Lbv5AJDh9o8 proper theme]] and Pursuit - Cornered! for his GameBreaker [[http://www.youtube.com/watch?v=IP9PoBlFDp4&feature=relmfu Turnabout mode.]] The fans aren't complaining, though.
** The same happens for [[VisualNovel/ApolloJusticeAceAttorney Apollo Justice]]. He has a proper theme used for his Objections, but many people also associate him with Investigation - Cornered!
* Another inversion of this trope occurs in the FireEmblemAkaneia. In ''Shadow Dragon'', the track entitled "The Proud Commanded" was the Leitmotif for Camus and Michalis. In ''New Mystery'', it's used as background music for any vaguely-intimidating boss, and even a few recruitable characters!
* ''ModernWarfare 2'' has: "Contingency" = [=TF141=], "Code of Conduct" = Shadow Company, "Siege"/"Infiltration" = Washington DC, and plenty of others.
* ''GearsOfWar 2'' has "March of the Locust" = Locust Horde, "Hope Runs Deep" = COG, "With Sympathy" = Maria, "Rolling Thunder" = Delta Squad(YMMV for this) and so on.
* The ''Franchise/TombRaider'' title theme and its variations = Lara's theme.
* In the ''VideoGame/{{Touhou}}'', a character's {{Leitmotif}} usually ends up being the music from their boss fight, but this trope happens a few times. Hong Meiling, Alice Margatroid and Youmu Konpaku all get their stage themes as {{Leitmotif}}s (along with their boss themes); Suika Ibuki gets her pre-battle theme (again, along with her boss theme). Also, midbosses (Daiyousei, Koakuma, Lily White etc.) usually don't have their own leitmotifs, so they tend to get associated with the theme of the stage they appear in.
* The song, [[http://www.infinitelooper.com/?v=t9BOjAHud4c Rowdy Rumble]] played during different mini-boss fights in ''KingdomHeartsII'', including most fights with {{Pete}}. The one time you fight Pete in ''Days'' also has this song, and in ''Dream Drop Distance'', encounters with Pete are the only time this song plays, ''period''. [[MickeyDonaldGoofyTheThreeMusketeers The Beagle Boys]] also get in on this song in the latter game, but they're Pete's personal lackeys and are later fought alongside him.
* Psychic Energy was originally a Map BGM in ''VideoGame/ShinSuperRobotWars''. It became associated with Aya Kobayashi in later SRW games.
* In the Maniax edition of ''VideoGame/ShinMegamiTenseiIIINocturne'', [[DevilMayCry Dante]] was given some leitmotifs reminiscent of his own series, and when he was booted off and replaced with Raidou Kuzunoha the XIV in the Chronicle edition, said music remained the same for Raidou.
* ''VideoGame/{{Persona 4 Arena}}'' features two cases of this for Yu and Aigis, who both get remixed songs from their respective games as character themes. Yu gets a remix of "Reach Out to the Truth", the normal battle theme from ''VideoGame/{{Persona 4}}'' (which is also oddly enough a BootstrappedTheme for the game as a whole). Aigis gets a remix of "Heartful Cry" from [[PlayableEpilogue The Answer]] portion of ''VideoGame/{{Persona 3}}'' [[UpdatedRerelease FES]] which plays during boss battles against [[spoiler: SEES members]].
[[/folder]]

[[folder:Visual Novels]]
* A peculiar example in ''VisualNovel/FateStayNight'': in ExpandedUniverse material, Archer usually gets a ThemeMusicPowerUp that is a remix of [[spoiler:"Emiya", the theme used exclusively for Shirou in the original Visual Novel]]. This example is strange because of the [[LateArrivalSpoiler spoileriffic]] reason that [[spoiler:Archer ''is'' a future version of Shirou, meaning that the song originally represented him in a way]].
[[/folder]]

[[folder:Webcomics]]
* Happens all the time in ''Webcomic/{{Homestuck}}''. This webomic has its own music team who typically compose themes based on their own visions, but which will often get used in the comic in a completely different context than they imagined. A specific example is [[http://www.youtube.com/watch?v=6A91UB3QkdE "Crystamanthequins"]], a song originally supposed to be music for Dave. It was later used in [[http://mspaintadventures.com/?s=6&p=004478 this flash]] and became associated with Vriska and Terezi instead; lately it has been showing up as a RecurringRiff in that context.
** One of John's themes, [[http://homestuck.bandcamp.com/track/doctor-2 "Doctor"]] ended up becoming a theme for [[spoiler: ascension to God Tiers]]. One of its remixes, "[[http://homestuck.bandcamp.com/track/savior-of-the-waking-world Savior of the Waking World]]", has a decent claim to being the theme for the webcomic as a whole.
** The drum beat from Upward Movement (first plays as Dave walks up some stairs) eventually become included in many different songs in Homestuck, such as Even in Death, Descend, and Terezi Owns (though the third makes sense as it is basically a mirror to the above-mentioned Upward Movement).
[[/folder]]

[[folder:Western Animation]]
* ''WesternAnimation/TheSimpsons'': Sideshow Bob's theme. His theme is the title music for ''Film/CapeFear'', since the episode it was first used in was a parody of ''CapeFear''. It wasn't meant to represent Bob, but since he was the bad guy, it naturally played only when he was onscreen. The producers ran with it and now it's quite explicitly his theme, always playing when he first appears in an episode (just in time for Bart and Lisa to shout in unison: "AAAAAAH! SIDESHOW BOB!").
* Due to being one of his most iconic cartoons, MickeyMouse has been increasingly associated with the ''WesternAnimation/SteamboatWillie'' theme.
* ''WesternAnimation/AeonFlux'''s theme tune was originally just a [[SuspiciouslySimilarSong Suspiciously Similar]] version of the theme from ''Franchise/IndianaJones'', as her debut short was a deconstruction of action movies. It was later remixed from a goofy, mock-triumphant, pseudo-orchestral sound into something more exotic and techno-ish for the later short ''Gravity''; this version then became her leitmotif in the TV series. The "Breen National Anthem", leitmotif of Aeon's main antagonists, has a similar story: it was originally created as the theme for a single Breen character, Vaarsche Lockney, meant to sound like a Creator/RichardWagner piece due to the character's Germanic looks...but it fit Bregna's authoritarian bent so well that the tune managed to outlast Lockney himself, who was spitted by an enemy swordsman half a minute into his first and only appearance.
* Among the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fandom, Rainbow Dash's verse of "At the Gala" tends to be considered her {{Leitmotif}} and often shows up as a RecurringRiff in fan-remixes based around her. It helps that it's ''very'' different from the other characters' verses, making it stand out more. Acoustic Brony's theme for her combines it with the verse of "Winter Wrap-Up", which has a similar motif.
** [[http://www.youtube.com/watch?v=eXNl2CXXWIA What was originally]] just BGM for a HardWorkMontage involving the Cutie Mark Crusaders eventually became their {{Leitmotif}} in general.
** Twilight Sparkle: MLP Main Theme
** Pinkie Pie: "Smile Smile Smile"
** Rarity: "Becoming Popular"
** Fluttershy: "So Many Wonders"
** Applejack: "Raise This Barn"
