->''You got the touch! You got the power... Yeah!''\\
-- '''Stan Bush''', [[{{Transformers}} "The Touch"]]

A character's strength and abilities are directly proportional with how [[RuleOfCool cool]] their [[{{Leitmotif}} personal theme music]] is. The more sudden it starts up and the louder it is, the more butt-kicking is about to commence. This applies to both heroes and villains and is a power that the BadassNormal is allowed to use. Alternatively, the music is a representation of the character getting into "the zone".

If a ThemeMusicPowerUp is defeated, then it's {{The Day the Music Lied}}.

If you're ''really'' badass, you get to have OminousLatinChanting, the OneWomanWail or the CherubicChoir. If you're ''totally'' badass, you get it to a techno beat or [[ThePowerOfRock heavy metal riff]].

Sometimes near the end, the series ThemeSong will play, allowing ''every'' good guy to kick some major rear at the GrandFinale.

!!Examples

[[folder:Anime & Manga]]
* ''The {{Slayers}}'': Lina has the same music anytime she casts Dragon Slave (and Giga Slave and Laguna Blade). Also somewhat distorted on the Battle Music (same everytime -- ''ikinashi oodate'') and totally distorted for Amelia and Gourry (with ''douchuuki'').
* Usagi of ''SailorMoon'' had several theme songs based on ThePowerOfFriendship. The Outer Senshi have their own RuleOfCool music.
** A bit different in the final season, in which the new addition to the cast -- the Sailor Starlights -- had an appearance theme very different to the traditional "sudden and loud" ones: starting quiet and subtle and then getting louder during the close-up on them.
** The English-dubbed version of the Season 1 finale features "Carry On" during the final battle, one of the very few improvements over the Japanese original (the original used the full-length [[AnimeThemeSong opening song]] "Moonlight Densetsu"). Other songs featured are "Ai no Senshi", "La Soldier" (from the Sailor Moon R finale), and "Moon Revenge" (from the R movie). The last episode of ''Sailor Stars'' uses the season's opening "Sailor Star Song" in this manner.
* Ichigo of ''{{Bleach}}''; whenever he was about to kick serious ass, his ImageSong ("Number One" by Hazel Fernandez) would kick in. This was subverted at one point: Ichigo moves to attack an unusually powerful badass, and his ThemeMusicPowerUp stops almost as soon as it starts when his opponent blocks the attack with a single finger. Yeah, that's right... [[spoiler:Aizen]] is so tough he can even defeat your ''theme music''.
** As [[http://www.youtube.com/watch?v=BXCVzlGsZP4 this video]] shows, "Number One" did provide a [[ThemeMusicPowerUp Theme Music Power Up]], but for the wrong character. "Number One" allows Renji to display some awesome, but as soon as Ichigo jumps into action, the fickle theme song is cutdown by [[spoiler:Aizen]]'s finger of doom.
** Ironically, the first proper use of the Image Song in the series was when it was used by the series' FakeUltimateHero to rescue Ichigo with his "Ultimate Attack".
** More recently, the BigBad and/or his [[EvilMinions Arrancar]] get classy, suspenseful Latin-style music in the background whenever they're making a grand entrance or are about to kick big-time ass. (This is in keeping with their Spanish-tinted theme.)
*** It's rather sad that it's been over a year since Ichigo has [[OutOfFocus managed to have a proper theme music power-up.]] And he's the main character!
* Kirika and Mireille of ''{{Noir}}''. [[OminousLatinChanting ''SALVA NOS, DEUUUUUS!'']]
** Similarly, anytime you start to hear Yanmaani (the song's title is "Nowhere") in the background in ''{{Madlax}}'', the titular character is about to kick serious amounts of ass with inhuman skill. It's so prevalent that The Other Wiki even mentions it. It is a joke among fans that the word gives Madlax super powers.
* The Twelve [=SISTERs=] of ''CoyoteRagtimeShow''.
* The climax of the ''[[GalaxyAngelGameverse Galaxy Angel]]'' [[GalaxyAngelGameverse games]] always follows the ThemeSong variant, playing that year's version of Eternal Love (or, in ''Galaxy Angel II'' games, Wing of Destiny).
* ''[[{{Dokkoida}} Dokkoida?!]]'' hangs a [[LampshadeHanging Lampshade]] on this; the hero's power suit is able to induce this state by playing a heroic theme song. At least if the company that made the suit actually got that feature working before they released it. But the hero doesn't know that, and he [[MagicFeather manages to get the same effect]] just from suggestion and enjoying the HotBlooded music.
* Pretty much every evolution sequence in every season of ''{{Digimon}}'' adheres to this trope. The more absurdly powerful the evolved form is, the more obnoxious and high-pitched the theme music will be, whereas less impressive evolutions (compared to the one available to the main character's partner at any given point in the series) often go by without music altogether. Also, true to this trope, evolution music invariably stops as soon as the evolved Digimon is hit by it's enemy.
** A good example occurs in the Adventure movie, Bokura No War Game. The evolution song, 'Brave Heart' plays throughout one of the battle scenes, and when Patamon tries to digivolve to his Adult/Champion level, he is attacked, at which point the music cuts out suddenly. It resumes around 30 seconds later when Taichi and Yamato's Digimon charge to counter attack. And then, before the computer crashes on Taichi, the line 'SHOW ME YOUR BRAVE HEART!' skips and replays several times, cutting out when the computer gets the BSoD
** Another example of the above happens in the episode where Greymon dark digivolves into SkullGreymon. During the battle scene, Brave Heart plays as normal, but a few seconds into the evolution scene, the song fades into a really dark and sinister piece of BGM.
** ''DigimonSavers'' adheres ''doubly'' so. There's a set of {{leitmotif}}s for various stages of evolution, but whenever [[AutobotsRockOut the J-Rock theme tune]] [[http://www.youtube.com/watch?v=D8Yh68qgU78 "Believer"]] cues up, you know the MonsterOfTheWeek is about to get beaten in a spectacularly flashy, HotBlooded manner. Sadly, due to the song being Japanese and the dubbing company having a music budget of about a nickel, it was cut in the domestic release, replaced with the more standard evolution {{leitmotif}}s.
** And in ''Adventure'', we have "Hey Digimon". It plays, then your screwed.
* ''CardcaptorSakura'' seems to have a {{leitmotif}} that appears on the soundtrack whenever she finally joins battle with a particularly powerful enemy. (If you've seen the show, you'll recognize it as a disco-style instrumental with oddly majestic sweeping strings playing the melody.)
* Various versions of a heavy, hot-blooded rap song are played during pivotal power-up moments in ''TengenToppaGurrenLagann''. Eventually they get so powerful that they actually get those lyrics superimposed on an ''[[OneWomanWail opera]]'' track.
** Mid-season brings another instance of this trope, when the song "Happily Ever After," which was originally just an extra track on the opening song's single CD, is played when the main character come out of his emo funk and turns into the leader he should be, complete with a 30 second beatdown on the up-until-then unbeaten [[TheDragon Dragon]].
** Finally, in the final episode, there is an actual theme-music power-up: the opening theme, which was omitted for that episode, begins playing and the real butt-kicking commences. The theme continues in its entirety until the final boss is defeated.
** Also works for the bad guys: whenever Viral shows up and does something awesome, the SurprisinglyGoodEnglish song "Nikopol" plays.
** Subverted in episode 25 where an attack is launched, a power up song starts... and the missile is harmlessly crushed before it can reach its destination. In all fairness, that wasn't the main theme song anyway.
*** Then played straight immediately after.
* ''FutariWaPrettyCure'': Nagisa and Honoka are undefeatable when the instrumental version of the theme song is playing. And if the background music has lyrics, they can accomplish miracles like defeating Jaaku King or getting Kiriya to turn good. At the end of ''Futari Wa Pretty Cure Max Heart,'' [[spoiler: the theme song was played with lyrics, which was both at once and thus gave Pretty Cure the ability to defeat the Jaaku King [[BackFromTheDead for real this time]]]].
** The ''All Stars Deluxe'' movie does this a total of ''four'' times. [[http://www.youtube.com/watch?v=0c5_XrkFTXw It happens once for each of the teams that had already finished their seasons]], and after this, the main theme of the movie plays for the final group attack.
* ''KonjikiNoGashBell'' brings a quite literal example of this trope. Italian Super Star Parco Folgore has a hit song known as "Muteki Folgore" (Invincible Folgore) with the ability to revive him every time he has been knocked down if it is sung by his partner Kanchome.
* The first season theme of ''HajimeNoIppo'' often plays during Ippo's final drive to victory in a given match.
** Subverted in one episode where during Ippo's first match against Japan Featherweight Champion Eiji Date, it is suddenly interrupted by Eiji's counter punch.
* When you hear Fate's voice actress, NanaMizuki, start to sing her insert song for that season of ''MagicalGirlLyricalNanoha'', expect every villain currently on screen to have their asses handed to them within the next five minutes. Fate gets a particularly big one of these in the form of the awesome "Pray" during the final showdown with Jail Scaglietti and the Numbers.
* Likewise, whenever "Meteor" or "Vestige" play in ''GundamSEED'' or ''GundamSEEDDestiny'', expect Kira Yamato to appear and disable the entire opposition without a scratch.
* Also in ''GGundam'', Domon Kasshu's theme "Gundam Rise" would play both when [[ExactlyWhatItSaysOnTheTin his Gundam rose]] beginning the fight, and to signal his Shining Finger attack and resulting in him owning whatever opponent he was facing during that episode.
* Many of the tracks of ''EurekaSeven'' are meant just as a theme music power up, be it for the heroes or the villains. Whenever Renton does anything especially awesome, a song insert, "Storywriter" begins playing.
** The first opening song, "Days", also lends itself to a ThemeMusicPowerUp for Renton and Eureka in episode 32.
* This was also done by ''NeonGenesisEvangelion''. Whenever EVA-01 is about to kick some ass and tear some unfortunate Angel a new one, a distinctice track known as "The Beast 2" plays. The track is even used for such moments in the crossover ''SuperRobotWars'' games. Also, in the series' original, ''MindScrew'', happy ending, when Shinji realises his whole life doesn't need to revolve around piloting EVA-01, and he can live a happy life without it, a slow piano version of the show's theme, "A Cruel Angel's Thesis", is played.
* The JamesBond-ish opening theme tune in ''{{Read or Die}}'' kicks up at the end of the first episode of the OVA, when Yomiko and Nancy square off against Otto Lilienthal and his transforming glider.
**And whenever you hear it fire up during [[ROD the TV the sequel]], strap in tight, because someone's about to kick some major ass.
* The titular character of ''{{Naruto}}'' has "The Raising Fighting Spirit", which assures he's about to [[MyNameIsInigoMontoya recover from a previous attack, and kick ass]].
** There is also "Utsukishi Aoi Yajuu" (Beautiful Green Beast) which plays for Rock Lee when he starts [[CrowningMomentOfAwesome WHOOOPING Gaara's keister]] in anime episode 48.
** Shikamaru has the techno song "Fake" which starts up whenever one of his genius plans is put into motion.
** Shippuden has "Heaven Shaking Event," which plays on several occasions, like when Naruto defeats the BigBad of the first movie, Team Guy finishes off their doppelgangers, and when Naruto defeats Kakuzu with his Rasenshuriken.
* In ''DragonBallZ'', when Cell goads and torments Gohan to transcend his Super Saiyan power, Gohan does exactly that, to a tune called "Demon vs. Demon" (in some translations). A fitting name, considering what Gohan basically becomes in this state. An alternate translation is "Spirit vs. Spirit"; the concepts aren't as different in Japanese as in English, but both translations fit the scene pretty well.
** In addition, in the dub of ''DragonBallZ'' there's a theme that plays for Goku during his first Super Saiyan 3 transformation. This music is also played during the entire Majin Buu saga whenever one of the heroes does something awesome.
** On top of that, Vegeta got such an awesome song that when I downloaded it from iTunes, it was the second-best selling Bruce Faulconer song, after the main theme. (March 2009) Oddly enough, it's called "Vegeta Super Saiyan", even though he's not always Super Saiyan when it's playing.
*** This is because Vegeta transforming to fight #19 was the scene that introduced the song
* The ''ShakuganNoShana'' cast get one in the climax of the fight against [[spoiler:Sabrac]] in Season 2.
* This happens in ''DeathNote'' whenever Light reveals whatever XanatosRoulette he has cooked up that week, just in case we had forgotten what a MagnificentBastard he is. [[spoiler:Near also gets one at the very end of the series.]]
** Likewise, whenever L really gets going, his guitar theme music flares up to match.
* "Little Busters" fills this role several times in ''{{FLCL}}'', usually when it plays during a Naota/Canti gattai.
* In ''KatekyoHitmanReborn'', there is separate theme music for "Look, someone (usually Tsuna) is no longer failing at life!" and "Oh, by the way, I acquired some new way to kick your butt. SORRY FOR NOT TELLING YOU!" ... as well as everything else, to the extent that it's possible to tell what's going on just by listening to the background music.
** To be more precise, the songs are called "Shibuki Time!" and "Tsuna Awakens", respectively.
* Both played straight, and played ''very'' straight by ''{{GaoGaiGar}}''. When Masaaki Endoh shouts "GA-GA-GA GA-GA-GA-GAOGAIGAR!", it's fair warning that Guy's power of ''raw courage'' is about to rip you apart. Meanwhile, Mic Sounders the 13th has a couple of songs on Disc P that ''literally'' power up any protagonist robot in earshot, restoring their energy and galvanizing their fighting spirit.
** Also, there are separate themes for the titular mecha's two big finishers, [[YinYangBomb Hell and Heaven]] and the [[DropTheHammer Goldion Hammer]]. Also, the rest of GGG's mecha get an extremely hot-blooded theme of their own when they're about to do some pretty awesome stuff.
*** The latter is heard most notably when they assault the Contra Fall, and is titled after the entire Mobile Unit: "Strongest Brave Robo Corps". This troper would also like to nominate two other songs: the J-Ark's save-the-day tune "Beautiful Wings Of Light", and the ominous guitar riffs during the opening of the Zonuda battle [[spoiler: where it pretty much wipes the floor with GaoGaiGar.]]
* ''[=~Pokémon~=]'' usually has one of the openings or upbeat endings accompany a sudden comeback (maybe even a whole battle) or evolution. "Pokémon Symphonic Medley" has been common recently, as there is no full version of the song.
* Almost the entire last episode of ''{{Stellvia of the Universe}}'' is accompanied by various theme music pieces, including the OP. The [[CrowningMomentOfAwesomeAnime sheer awesome]] of its GrandFinale takes more than words to convey.
* ''{{Gravion}}'' has a theme song that plays when it combines, in one episode Sandman and the maids ''[[http://www.youtube.com/watch?v=At9HFJ6pGdY powered the robot up by singing karaoke!!!]]''
** Sol Gravion has its own theme towards the end of ''Gravion Zwei''. The names are ''Gasshin! God Gravion'' and ''Enou Gasshin! Sol Gravion'', respectively.
* Inverted in ''ParanoiaAgent'', where the Theme Music belongs to BigBad Lil' Slugger. If it starts playing, you're ''extremely'' screwed -- Slugger gets the powerup.
* ''MacrossFrontier'' does this a lot, especially episode 7. In episode 14, [[spoiler:it's subverted -- "Don't Be Late" plays as Sheryl goes into combat for the first time... only for her to be immediately shot down.]]
** In episode 24, [[spoiler: [[SubvertedTrope it is subverted horrifically]] for the Frontier fleet, as Ranka sings "Ai Oboete Imasu Ka" ''for the Vajra'', which proceed to overpower the human forces]].
** The entirety of episode 25 [[spoiler: is pretty much THE defining example of Macross {{ThemeMusicPowerUp}}s, combining almost every song in the series. [[http://www.youtube.com/watch?v=2J_kvVCdGUU One segment]] is a perfect microcosmic demonstration of the trope, including both the loss of power/end of song coinciding and the power/song starting back up with increased fury.]]
* ''{{Genesis of Aquarion}}'' has a ThemeMusicPowerUp in nearly every episode (along with the usual subversion with stopping the song when the attack fails), and the last episode gets an awesome, gospel style version of the first theme song.
* ''UminekoNoNakuKoroNi'': For the protagonists "worldend_dominator", "Far", and "Dread of the Grave" are all indications that a CrowningMomentOfAwesome will happen. For the antagonists it will be "happiness of a marionette", "mirage coordinator", "Golden Smile", or "Moon Rabbit's Dance".
** ''HigurashiNoNakuKoroNi'''s games have it's own series of Songs, with various remixes of 'Dear You'. The instrumental version, 'Dear You - Destructive' is used during one of most Crowning Moments of Awesome, needless to say, Keiichi dodges bullets.
* ''{{Princess Tutu}}''. Admittedly, all combat is to ballet music, but you could always kind of tell who exactly was getting the power up.
* ''{{Eyeshield 21}}'' also has some examples of the "with lyrics" variety. The first appearance of "Be Survivor" comes to mind and, later "Chain of Power."
* The ''DevilMayCry'' [[DevilMayCryTheAnimatedSeries anime]] has a pretty cool theme song, which plays during the final episode when Dante activates his Devil Trigger to finish off the BigBad. We don't see the full Devil Trigger and the fight is over in a few seconds, but the music makes the scene an odd combination of MissedMomentOfAwesome and CrowningMomentOfAwesome.
* ''BurstAngel'' only has this happen in the last episode, [[spoiler:when textbook DistressedDamsel Meg, [[PercussivePrevention Percussively Prevented]] by her [[HeterosexualLifePartners partner]] Jo from suicidally StormingTheCastle, finally starts to stand on her own, taking the first steps toward [[TookALevelInBadass Taking A Level In Badass]].]]
* ''ShikabaneHime'' played the OpeningTheme over Makina and Yamagami's first fight with Akasha to let them fight his horrible evilness.
* Once [[FistOftheNorthStar YOU WA SHOCK/Ai Wo Torimodose]]'s battle remix starts playing (or for that matter, the fight alteration of "Super Survivor" or "Tough Boy"), then there's no doubt Kenshiro will bring the ultimate form of pain on the bad guy of the day. Then, after the beat down, [[CatchPhrase they are]] [[YourHeadAsplode already dead]].
** One aversion however, is Jackal, a powerless dynamite-{{Spam}}ming mook, who manages to live all through that music. And Ken was just fucking with him all that time anyway... up until Jackal calls upon Devil Rebirth.
* ''{{Vision of Escaflowne}}'' does this sometimes. When the Dance of Curse starts playing expect some serious fighting.
* ''OnePiece'' has "Gomu Gomu no Bazooka!", which often plays when Luffy finishes off the villains.
** Each character has their own. If a non-Strawhat has one, they're joining the crew.
** If you hear the instrumental version of "We Are" (The show's first theme song), the whole '''crew''' is going to be breaking out the beatdown.
* During episodes 18 and 19 of the ''[[{{YuGiOhGX}} GX]]'' dub, the duelist who purloined Yugi's deck and was dueling Jaden kept having musical overtures from the previous series playing. Towards the end, they were even being played in the same musical style as a lot of GX music.
* ''{{Basquash}}!'' doesn't show the usual title card or play the theme song at the start of episode seven, with the reason why being revealed at the end. It was being saved for Dan showing Rollingtown, for real this time, how {{hotblooded}} basketball is played. The theme song shows him the way.
* Nearly any fight in ''TheThird!'', most notable [[OneWomanWail One Woman Wail]] "Sword Dancer" during first and tension rising "Storm on the Battlefield" during last battle.
* Most fights in ''{{Law of Ueki}}'' start the opening theme as the final attack is used, which then continues through the whole opening, even if the fight has already ended.
* Whenever Yuki Kajiura and the strings and chimes of Awesome strike up in ''KaraNoKyoukai'', not only is the unkillable going to be killed, it's going to be ''spectacular.''
* In the ''BlackLagoon'' anime, various rock songs inevitably start up whenever awesomeness is about to come down. The most notable is the song "Peach Headz Addiction", which only plays when Revy lapses into [[TranquilFury Whitman Fever]].
* In the final episode of ''OuranHighSchoolHostClub'' the ending theme starts early as [[spoiler:Haruhi goes after Tamaki on the carriage on her own]] and the episode had a special ending to avoid repeating.
* Whenever Athena's Saints in ''SaintSeiya'' mustered their courage and [[CatchPhrase burned their]] [[BattleAura Cosmo]] beyond its limits, they'd receive either [[http://www.youtube.com/watch?v=UGVMUQQI6Cg a full-on brass fanfare]] or a gorgeous orchestral arrangement of "Pegasus Fantasy". Asskicking of Olympian proportions would ensue.
* In Gaiking, should you happen to be hearing the sound of trumpets - it means Daiya is about to kick ass.
* ''TransformersVictory'''s opening theme music plays whenever Star Saber does something particularly awesome. Road Caesar and Landcross each have their own remixed version.
* In ''SetoNoHanayome'', San's "Song of Heroes" ''is'' a ThemeMusicPowerUp, thanks to the [[MagicMusic Mermaid's Ancient Lyrics]]. Any time San starts singing it, [[BadassNormal Nagasumi]] is about to do something impossibly badass. And then there's the time that [[spoiler: Nagasumi pulls it off ''before San starts singing'', because he's just [[UnstoppableRage that pissed off]]. The "Song of Heroes" starts picking up just as the asskicking begins.]]
* ''KeroroGunso'' example. In episode 103, just as [[spoiler:the Garuru platoon has utterly defeated the Keroro platoon, Natsumi is down and Keroro himself has been transformed into a psycopathic frogchild version of himself, Fuyuki snaps him out of it...cue the first opening theme as Keroro rallies the troops. 3! 2! 1! FIRE!]]
* ''RevolutionaryGirlUtena: TheMovie''. "Let's go, Utena. To the outside world." ''~ Oooohhhh, yeeeaahhhh... ~''
[[/folder]]

[[folder:Films]]
* [[http://au.youtube.com/watch?v=BFtM-YOlc8c The Heart-Stirring main theme]] of ''{{Once Upon a Time in China}}'' plays whenever Jet Li's heroic lead, Wong Fei Hong, [[http://au.youtube.com/watch?v=G9ZVwrzCbuw&feature=related takes on]] [[http://au.youtube.com/watch?v=_VQKBCh218w the forces of evil]] [[http://au.youtube.com/watch?v=fHi3izaoi_A in said-movie-series.]]
** It's traditional to use that for Wong Fei Hung's theme song in any movie about him. Example:[[http://www.youtube.com/watch?v=e8Iic9EUqdA&feature=PlayList&p=7808BAA09560C5BE&playnext=1&playnext_from=PL&index=19 This clip]] of Jackie Chan's Drunken Master plays it when Fei Hung is winning his fight against the BigBad.
* The Bride from QuentinTarantino's ''KillBill''.
* ''IndianaJones'' has his distinctive theme play whenever he does something Especially Awesome.
** Said theme was so awesome that ''TurkishStarWars'' shamelessly stole it and used it for Every. Single. Freakin'. Fight scene.
* ''JamesBond'' is in the rare and enviable position of having ''two'' [[ThemeMusicPowerUp Theme Music Power Ups]] -- the "James Bond Theme", and the music from the opening titles of each movie. See the [[http://www.youtube.com/watch?v=2WgVUzVxUkM pre-credits sequence]] from ''TomorrowNeverDies'' for a particularly badass example. On the other hand, if the opening song is a ''VillainSong'', Bond had better watch out when it starts playing on the soundtrack. Example: [[GoldFinger Goldfinger's]] [[CrowningMomentOfAwesome aerial raid on Fort Knox]], set to a thunderous version of his TheVillainSucksSong.
** Two examples that simply '''must''' be mentioned:
*** Bond re-entering the scene in a ''tank'' by taking the shortest route ''through'' a concrete wall in ''{{Goldeneye}}''.
*** ''[[CasinoRoyale "The name's Bond... James Bond."]]''
* In the ''Film/{{Spider-Man}}'' films, Spidey's action scenes are usually accompanied by his distinctive {{leitmotif}}. The villains also get their own theme music. In climax of the third one, Spider-Man's theme gets very noticeably cut off whenever the villains get the upper hand.
* "Holding Out for a Hero" in ''Short Circuit 2''; for those too young to remember that one, it was also in ''Shrek 2''. With full orchestra support from Harry Gregson-Williams in the latter case.
* At the end of the ''Mission Impossible'' movie.
** Even better in the second one, when [[spoiler:the hero is dead and the villain victorious (complete with his own music rising to climax), only to change abruptly to the hero theme as we see that he (and we) have been deceived.]]
* Right towards the end of the ''TheMatrix'', when Neo becomes [[TheChosenOne The One]], and is seeing the "code" for the first time. One-handed kickassery follows.
* The ''{{Rocky}}'' movies are no doubt well-known for their sudden comebacks, almost always accompanied by one of Rocky's many theme tunes. Usually, just as the finishing blows are made, the music builds to a dramatic climax. This is no more evident than in the fifth movie (otherwise not worth the time) where, as Rocky lies concussed in the streets during a brawl with Tommy Gunn, he goes into an almighty hallucination, remembering his dead trainer Mickey before finally snapping out of it as Mickey screams at him "Get up, you son if a bitch... 'cause Mickey loves ya." The music swells as Rocky rises again... then it suddenly bursts into a weird ghetto remix. Still, this editor has to admit he always gets a bit teary eyed at this part, no matter how cheesy it is.
* Parodied in ''Kung Pow: Enter the Fist'', where Master Betty occasionally shouts, "Play my kick-ass music!" One of his minions then plays "Baby Got Back", to which tune Betty pummels his victim.
** "By the way, you must beware of Betty's iron claw. They are sharp, and they hurt. And beware his song about big butts, he beats people up while he plays it!"
** And in the final showdown, the Chosen One throws a shuriken at the boom-box, causing it to start playing the Ram Jam version of (probably) Huddie "Lead Belly" Ledbetter's "Black Betty".
* Sometimes done just before a scene's climax, when the heroes have the upper hand and the enemy hasn't made his final play yet -- such as in the ''ScoobyDoo'' movie, where a remix of the classic theme plays for a while before the gang really winds up in trouble.
* "Secret Agent Man" playing in the final battle of the first ''AustinPowers'' movie may qualify; again, it dies down before Austin's final confrontation with Doctor Evil.
* Backs up the Guarani a couple times in ''The Mission''. Sadly, [[HopeSpot it is not quite enough]].
* The first twenty seconds of the track "Beelzeboss" from ''Tenacious D in the Pick of Destiny'' act as a ThemeMusicPowerUp for [[{{Satan}} the Devil.]]
* At the end of ''{{Pirates of the Caribbean}}: Dead Man's Chest'', Jack Sparrow's confrontation against the kraken is made even more awesome by the remix of ''He's A Pirate'' that plays during it.
** And then abruptly turns tragic as the heroic strings drop into a dying fall... just as the ''Black Pearl'' is pulled beneath the waves.
* How can anybody forget how ''Film/{{Excalibur}}'' popularized "O Fortuna".
* ''StarWars: Return of the Jedi'' gives Luke a big ThemeMusicPowerUp in the Sarlacc pit scene.
* This troper ''swears'' this is the case with Mr. Mistoffelees on the filmed version of ''Cats''. His song, though enjoyable, is so odd and repetitive and full of praise that it seems he's doing the song mostly to get the crowd to [[ClapYourHandsIfYouBelieve believe in his powers]] so he can actually ''do'' anything.
* When it's time for a dogfight, what's the first thing the hero does in ''[[http://www.imdb.com/title/tt0091278/ Iron Eagle]]''? Put some rock into his tape deck, of course.
* Why the ''{{Superman}}'' wasn't added a long time ago is beyond me. It ''is'' the sound of powering up.
** Later used/homaged in a climactic moment of ''[[ImAMarvelAndImADC I'm A Marvel... And I'm a DC]]'''s "After Hours" storyline. The circumstances did it justice. Which is to say, it was appropriately ''awesome''.
* In ''{{Godzilla}} Final Wars'', Godzilla's new theme "King of the Monsters" kicks in just as he blasts off one of Keizer Ghidorah's heads after being revived by Ozaki in the Gotengo. Godzilla then proceeds to utterly destroy Ghidorah by tossing him into the air and blasting him with a spiral beam.
** A possible subversion or inversion could be the laughably quick death that the American Zilla receives from the true Godzilla while the English (but not American) song "We're All to Blame" plays over its fight.
* In ''GalaxyQuest'', at the end of the movie, the real ''Protector'', with the cast members on it, crash-lands at a ''Galaxy Quest'' convention. The film's BigBad, Serris, is still alive -- until he's shot, in full view of the entire convention audience, by "Commander Peter Quincy Taggart". The film's triumphant theme music plays. It's over. However, in the beginning of the movie, the guy was a pure egotist, basking in the spotlight at appearances and so on. Now, he's learned his lesson, and he invites the crew up to take a bow. When this happens, the music switches to a higher, remixed triumphant version with plenty of choir -- the Commander's won the ''real'' battle. The movie ends there.
* ''Iron Man'' had great fun with this, playing the driving guitars of the hero's theme and then stopping the music abruptly when circumstances changed. Best example would be [[spoiler:our hero taking out a group of terrorists and flying along with music blaring until he takes a tank round to the face and crashes. He stands up, fires with disdain a tiny little rocket, and turns around to walk away. Looking back, we see the tank explode dramatically and the music picks up right where it left off.]]
* "[[{{YorTheHunterfromTheFuture}} Yor's world, he's the man!"]]
* Two moments from ''StarTrekFirstContact'' spring to mind: the battle againt the Borg cube at the start of the movie, where the ''Enterprise'' [[BigDamnGunship swoops to the rescue]]to the sound of an absolutely ''epic'' [[http://www.youtube.com/watch?v=miaOx3UrLA4 fanfare]], and the fight on the deflector dish, where each time the Borg gain the upper hand, a more thunderous version of their {{Leitmotif}} [[http://www.youtube.com/watch?v=OWxOCuk6rMs plays]].
* Pretty blatant in the climactic fight scene of ''OnlyTheStrong'', a 90's action film about capoeira (a Brazilian martial art): [[spoiler:the main character is about to be killed by the BigBad, when all of a sudden the main character's student's (who are watching the fight, along with the Big Bad's minions) start singing the capoeira song he had taught them earlier in the film. This gives our hero the energy boost needed to fend off his opponent, then royally kick his ass.]]
* Whenever [[TransformersFilmSeries Optimus Prime]] enters the big ending battle in both movies, the music soars as Prime either [[TechnologyPorn epically transforms]] or [[spoiler: gets new armor, weapons and flight capability donated from the deceased Jetfire.]] Both complete with a one-liner to emphasize that yes, this is awesome.

* An affectionate parody: Acheron, the Atlantean god-turned-vampire warrior of Sherilyn Kenyon's ''Dark-Hunters'' series, has "Sweet Home Alabama" for his theme music.

* ''XenaWarriorPrincess'', as sung by the Bulgarian Women's Choir.
* Numerous examples in ''PowerRangers'' in all of its incarnations. For example, after Tommy lost his Green Ranger powers in the first season, yet proceeded to fight off Goldar anyway (to the tune of "Go Green Ranger Go").
** Theme Music Power Up is the only context where we get to hear the original Power Ranger theme with ''lyrics'' in its verses. ("No one will ever take them down / The power lies on their si~i~i~i~i~ide! / Go, go, Power Rangers...") For this troper, giving a previously instrumental theme some lyrics, when done right, seems to give a power-up ''to'' the theme music.
** Particularly, in the crossover episodes, the visiting team gets the theme music for the previous season when they escalate. In ''Operation Overdrive'''s ''Once a Ranger'', we're treated to five earlier incarnations of the theme music, cleverly mixing together (Well, four; for some presumably legal reason, Adam gets a new theme song rather than the original "Go, Go Power Rangers" theme.).
** Happens in ''SuperSentai'' too... although [[http://www.youtube.com/watch?v=yuYPrmUWQFk ''Fiveman'' took it too far.]]
** Some ''Power Rangers'' series have also inverted this trope, giving Mooks like the Cogs and Tenga theme music when they fight the Rangers. They almost always lose.
*** This happened in Sentai too, dating [[OlderThanYouThink all the way back to Goranger]], with "Akuma no Kurojuujigun" being the theme of the Kurojuujigun.
* One series, ''Kagaku Sentai Dynaman'', (yes, [[GagDub that one]]) had this to the extreme, with an opening theme made to sync to the FinishingMove, the Super Dynamite.
* ''TokusouSentaiDekaranger VS Abaranger'' ended up ''[[{{LampshadeHanging}} Lampshading]]'' the whole thing:
-->'''Jasmine:''' Please excuse me. ''(place hand on Ryouga's hand)''\\
'''Narrator:''' ''(while clipshow of Abaranger goes on)'' Jasmine is an [=ESPer=]. Whoever she touches, Jasmine recaps his memories.\\
'''Jasmine:''' Seems true for now. I have my doubts for them though -- ''(walks to the camera)'' -- ''[[{{DancingTheme}} Aba-Aba-Aba-Aba-Abaranger!]]''\\
'''Umeko:''' What the heck was that?\\
'''Jasmine:''' Don't know either. It was on loop in his brain.
* ''TheATeam'' theme tune, during each episode's ATeamMontage.
* ''KamenRider Den-O'' has a different version of "Double-Action" for each of Ryotaro's five forms. Ryuutaros, however, takes it a step further. He gets a hip-hop remix of the show's ThemeSong and the above mentioned "Double-Action", that play almost every time he shows up. This includes when he's stalking rival Sakurai Yuuto. Speaking of, Yuuto and his partner Deneb get their own theme music, called Action-ZERO.
** All {{Toku}} use this trope to one degree or another. [[GrandFinale Grand Finale]]s usually involve the "series Theme Song" variant, while the debut of [[SixthRanger Sixth Ranger]]s usually gives them a specialized theme. [[MerchandiseDriven This may be to sell the soundtracks]].
** Though it doesn't quite fit under a category, when one of the Riders in ''Kamen Rider SPIRITS'' is about to have a nice big one-against-all-of-his-monsters-of-the-week-ever battles, the lyrics to an appropriate theme song are written out on the page (V3's sequence is notably impressive).
** Especially powerful in Kamen Rider BLACK's final episode when [[spoiler: Kotaro powers up with Long Long Ago 20th Century in the background to fight his brother, Shadow Moon one last time.]]
* Not really sure if this fits, but at the end of the Season Finale of ''DoctorWho'', a rather magnificent version of Martha's theme plays when [[spoiler:she leaves the Doctor, returning to her family as the TARDIS dematerializes. The implication is that she will go on to have an amazing life without being in the Doctor's shadow constantly.]]
** Better examples would be the [[OminousLatinChanting Ominous Hebrew Chanting]] that plays whenever the Daleks do something particularly awesome (which is a lot), or the four-beat "sound of drums" that plays whenever [[spoiler:the Master]] is a MagnificentBastard (which is a ''lot'').
*** Of course this could be considered a subversion, as in the later's case it turns out [[spoiler: he hears it constantly, and its driven him insane]].
** The Doctor himself has ''two'' themes (not including the Main Title theme) in the new series: one for whenever proceedings get "too Time Lord-y", and another, bombastic epic theme to underscore various moments of heroism. In particular, the second theme played over a moving Remembrance Day service at the end of ''The Family of Blood'', while the former was epic-ized for [[spoiler:the Doctor's aristeia in ''Forest of the Dead''.]]
* ''{{Airwolf}}'', a lot, including literal cases, where the theme tune plays as Airwolf starts up, and goes full-blast during the climactic fight scenes. In fact, you can usually predict down to the second when the final explosion will take place as it will be in time with the climax of the theme.
* On ''Series/{{Heroes}}'' a ticking clock sound starts playing whenever Sylar gets up to his serial killer shenanigans. It fits his backstory as a watch repairman, and is damn creepy to boot.
** In the Season 3 episode "I am Become Death", this trope is played around with when Sylar's theme is played again for another character, [[spoiler:Peter, as he loses control while trying to use Sylar's power.]] It's creepy and effective.
* ''{{Batman}}'' usually fought goons to the sound of his theme music. And it was ''AWESOME''.
** Doubly awesome as every BIFF and POW is accented by a musical sting.
* ''{{Spaced}}'' spoofs by powering with another show's theme: Mike gets brooding MadArtist Brian to go from mouse to man by playing the ''{{Thunderbirds}}'' theme.
** Another episode uses a drum and bass remix of the [[StarWars Imperial March]] over a MissionBriefing scene as Tim tries to power up the rest of the gang.
** "Where's Mike?" "He's over there!" [[http://www.youtube.com/watch?v=ayknw2gcUBU Dancing to]] a [[CrowningMusicOfAwesome dance remix of the A-Team theme]].
* ''BuffyTheVampireSlayer'' did this at the end of the first season.
* In an example of the character playing their ''own'' theme song, basically any time Omar Little of ''TheWire'' whistles "The Farmer in the Dell," odds are he's about to add yet another act of pure badassery to his resume.
* Everytime Grover transforms into Super Grover in SesameStreet (He gets a version with Rock Guitar in ''Elmo Loves You'')
* Happens in the very first episode of ''StarTrekTheNextGeneration'', when the crew successfully pull off the detachment of the saucer section at Warp 9.
* Oddly enough, even a network can be powered up through theme music. Remember [[http://www.youtube.com/watch?v=i1NKoMNy5bY "HBO in Space"]], the intro HBO used in the 80s and 90s for movies on Saturday night and such? Where the camera zooms through a town, then up into space, where the HBO logo flies at you, twirling? People commenting on that video repeatedly state how the music gets them pumped up, feeling like they're about to watch something epic!
* This happens twice in a single episode of the reimagined BattlestarGalactica. In Exodus Part 2, [[spoiler:during the escape from New Caprica some fairly standard, percussion-heavy music is playing, until the Galactica shows up ''falling from the upper atmosphere, launches vipers, and jumps away at the last second'', all of which is set to the most triumphant bagpipes you can imagine. Later, as Galactica is getting pounded by four Cylon basestars and everyone has given up hope, the music is slow and somber. The camera pans out until a missile appears from off screen, and then another one, until the camera turns around to reveal the Pegasus [[BigDamnHeroes in the nick of time]] and the music the music goes back to the exciting drum music.]]

* ''{{Popeye}}'''s use of this trops was parodied in ''PearlsBeforeSwine'' where the croc forgets to chew the spinach before swallowing, and chokes to death. ("[[FunetikAksent Tooday's]] lesson: [[SpoofAesop Always chew you food]].")
[[/folder]]

[[folder:Video Games]]
* ''PhoenixWrightAceAttorney'' uses this trope to extremes unplumbed by man, playing it straight and subverting it at will as the case swings back and forth in and out of Phoenix's favor. A DoubleSubversion occurs in the first game's third case: Phoenix is out of ammo, the witness/killer is about to get off the stand... and then the song "[[http://uk.youtube.com/watch?v=Cy2QYE90BUI&feature=related Investigation ~ Cornered (Variation)]]" (very dramatic and heroic music) starts up as Edgeworth objects to keep the witness on the stand. The music dies as Edgeworth realizes he doesn't have a question, the judge is about to let the witness go... and then the music starts up ''again'' as Edgeworth has a burst of inspiration.
** The second game uses this in an interesting way: [[spoiler:Edgeworth returns from a JourneyToFindOneself. Part of the sign he found what he was looking for is that he has gained his own theme music.]]
** This happens again in ''Trials and Tribulations'' when [[spoiler: Phoenix finally backs Godot into a corner, exposing as the true "murderer" of Misty Fey. As he does, the "Cornered" song from the first game reappears. Mia Fey's spirit even shows up to cheer Phoenix on.]]
*** This event is made even more awesome by the fact that the last time you heard that song was in the [[strike:first game]] an early flashback in the 2nd game, because the 2nd and 3rd games had a new song for the situations "Cornered" was used in. When this troper heard the first bits of it as the song begin, he got even more pumped than he already was.
** In fact, the use of this trope verges on being a ''gameplay element'' - whenever you present the correct evidence at a contradiction, the cross-examination theme will ''always'' stop as Phoenix objects, in preparation for the heroic music to start up once he points out the contradiction. If you're wrong, the music will just keep going as he takes a penalty. This troper saved right before every objection she wasn't sure of, and waited for the music cue with her finger on the power switch in case she was wrong...
*** However, based on this troper's experience with the first game, there has been at least one case where the music stops even if you present the wrong evidence anyway, fooling you into thinking you had the right one.
*** And in the second to last piece of evidence of the third game (the one with the first game's "Cornered" theme) the music always stops and Godot's next line is the same if you present the right piece of evidence or not.
** In the third and fourth games, the main prosecutors had their own theme songs, both of which ROCKED ASS. Whenever their song begins playing, this troper would think any variation of the phrase "Shit. I'm about to get '''OWNED.'''"
*** In the fourth game, the prosecutor was a guitarist for a band and his theme music turned out to be one of his actual songs. Further, he will perform '''awesome''' air guitar in court, which does everything from double your penalty bar to break down a witness.
*** Don't forget Godot. He has his own smooth jazz Leitmotif as his CELL PHONE RINGTONE.
* In the Gamecube version of SoulCalibur 2, Link's theme starts blaring as he begins his destined battle against Raphael. Hearing the tune really pumps you up to kick Raph's arse.
* ''Super Metroid'''s FinalBattle, where the remixed Crateria theme starts thundering over Samus' "MyNameIsInigoMontoya" moment against Mother Brain.
** Samus does have her own theme music by this point in the series, which plays over her revival (both times) in ''Metroid Prime 3: Corruption'' and over ''Super Metroid's'' opening text crawl and end credits. It also gets an orchestral remix in ''SuperSmashBros Brawl''.
* Speaking of ''{{Metroid}}''... Late in ''Metroid Zero Mission'', Samus is stripped of her armor, and is forced to retreat from a pack of murderous space pirates who can kill her in one shot. She gets two consecutive Theme Music Power Up moments:
** After gaining a new, more powerful version of her armor in the Chozo Ruins, Samus gets the "got item" theme, but instead of the [[ShoutOut version found in the 8-bit NES Metroid]], it sounds more like the Metroid Prime-and-later versions. Sends chills up and down the spine.
** Samus then retaliates against the pirates with a vengeance, now able to destroy ''them'' in one shot, with an up tempo version of the ''Brinstar'' theme song blaring all the while.
* The final boss of ''MetroidPrime'' is accompanied by the already slightly creepy, OminousLatinChanting filled main menu music, warped to sound even stranger and more alien. Given that the main menu has the interior of a metroid for its backdrop, this really drives home just how ''wrong'' the final boss is, even compared to life energy sucking floating fanged jellyfish.
** Both Ridley and Dark Samus have Evil Theme Music Power Ups in ''Metroid Prime 3: Corruption''. In the case of Dark Samus, it's a [[BigDamnHeroes Big Damn Villain]] moment too.
* ''MetalGearSolid 3'' invokes the song ''Snake Eater'' if the player is running out of time in the final battle [[spoiler: with The Boss]].
** ''MetalGearSolid 4'' plays with this, where playing certain songs on the IPod provides ingame bonuses. Naturally the ridiculously awesome ''MetalGearSolid 3'' theme (''Someday, you walk through the raaaaaaain, some day you'll feed on a treeeee frog!'') makes you almost unstoppable.
*** Then there's the finale of ''MGS4'', where [[spoiler: a final fistfight with Liquid Ocelot comes in four parts, with theme music from each main game of the series (and matching health bars) for each section, until the music runs out of steam and it's just two old men throwing their last ounces of strength at eachother.]]
* ''MegaMan'' series examples:
** Zero in the ''MegaManX'' games has a different theme song in every game, and it always plays when he does something awesome (blowing off Vile's mech's arm in the first game, sacrificing himself, destroying a copy of himself in just three shots, etc.).
** This holds true in the ''MegaManZero'' saga. Whenever that particular game's Zero theme song starts sounding, rest assured -- you're about to do something very cool.
*** Also, the music changes into the foreboding final stage theme after the first form of the final boss is defeated and [[spoiler:the Ragnarok satellite is plummeting toward the planet with Weil making a last bid by [[BodyHorror hooking up to the remains of its control system]] and directing it towards Area Zero]]. Then Zero has his WorldOfCardboardSpeech and the absolutely awesome final boss music starts up.
** And ''MegaManBattleNetwork'' games have a theme in each game, based around the same two tunes throughout the series, which is played for no other reason other than to show off how something heroic is going on.
*** The tracks are actually called "Heroism".
*** Not to mention "You're Not Alone" for the BigDamnHeroes moments.
*** In what can only be described as MoodWhiplash, the 6th game has a slow, sad version of the theme, as [[spoiler:Iris and Colonel reveal that they are going to fuse, deleting them]] to get rid of the Cybeast inside the titular character, then "You're Not Alone" plays as the event actually ''happens''.
*** The ''[[MegaManNTWarrior Battle Network]]'' anime even did this in the Japanese version -- if you heard the theme song, it was time for the heroes to start winning. Without fail. This troper personally wondered if the heroes summoned the theme music, or if they actually ''needed'' the theme music to win the day. The dub did not retain this tradition.
*** The final match of the [[TournamentArc N-1 Grand Prix]] was, of course, between Netto and Rockman and [[TheRival Enzan and Blues]]. The fight takes place while the AnimeThemeSong, "Kaze wo Tsukinukete", blares in the background, and both Navis pull off the Program Advance Beta Sword and commence a swordfight so epic the holographic display almost can't contain it. And then Blues ''wins'' by way of SingleStrokeBattle. Rock falls over, and Blues and Netto both congratulate Rock on his hard fight while a slow, sad ballad version of the very same opening theme plays.
** In ''MegaManZX'', you get a brief moment of your protagonist's bright idealism, accompanied by Green Grass Gradation (the very upbeat and optimistic Area A music from the very beginning of the game), before commencing the final battle.
* During the second fight with Dracula in ''Super {{Castlevania}} 4'', the music changes from the level music to Simon Belmont's theme. Note that this has worked in reverse as well; Dracula's theme music, Dance of Illusions, usually plays in the fights where he's the most difficult to defeat (like in ''Dracula XX'', where the battle takes place over a series of bottomless pits).
** Two examples of this one in ''{{Castlevania}}: Aria of Sorrow''. In the first example, when you enter the boss room for The Arena, the normal boss music plays, as a cloud of bats flies outward and reforms into one Giant Bat. ''Then,'' a giant hand stretches out from the background (a huge shattered cage) and crushes the bat in its grip, just as the music changes to an entirely new boss theme. You end up fighting Balore (a giant ogre), one of the tougher bosses in the game.\\
The second example is in the extended ending. If you fight the normal final boss, Graham, a certain way, you will [[spoiler: inherit Dracula's powers once you defeat him.]] This allows you access to a previously sealed area of the castle... [[spoiler:where you get to fight Julius Belmont himself!]] The battle is a tough one, too -- especially because [[spoiler: Julius]] has the best theme music in the game.
* This is essentially the effect of Star Power in the ''GuitarHero'' games. Once activated, every note you successfully hit earns you double points, and the crowd rhythmically claps in unison. This is a great way to save you from certain death on difficult songs like "Bark at the Moon" and the faster second half of "Hangar 18".
* Used throughout the ''{{Halo}}'' series. The Halo Theme generally starts playing whenever things get particularly exciting -- a narrow, timed escape, a huge, 3-way battle, etc. And, of course, whenever Master Chief does something utterly awesome, the theme WILL be playing.
** Depending on how awesome whatever Master Chief is doing is, you might get the "Brothers in Arms" mix, the "Rock Anthem / Mjolnir Mix," or the "Covenant Dance" mix.
** The best example of this music being used is in the final mission of ''Halo 3'', which consists of one of the most epic escape sequences in video game history.
** The Arbiter actually gets a mix of his own as well: "Unyielding," introduced in Halo 2, which plays when riding into battle against the Brutes in the last few levels. This track is later spliced into the ''Halo 3'' version that plays during the big escape at the end.
* Each area in ''PhantasyStarOnline'' has two songs (or parts if you see the song listing in the Sound Test or the OST). Part one is soft and calm while part two is more intense and has a harder beat to it. Both parts last almost the same length and have the same BPM, which lets the BG music flow from one song to another as if it were just the same song just getting more intenser. The intensity between the parts goes up with each episode as well.
* ''{{Sonic the Hedgehog}}'' has been doing this lately.
** To be more exact, when someone goes Super at the end of each game, it is ''always'' accompanied with a ThemeMusicPowerUp.
** Odd; this troper thinks of the "invincibility stars" music from the first game as being the Sonic theme. Which is sort of a clever setup -- unlike Mario, when Sonic goes kill-everything-I-touch invincible, he gets his theme music to accompany it, making this trope self-fulfilling.
*** ''Unlike'' Mario? Have you forgotten the SuperStar? do-do-do dodododo-do do-do-do dodododo-do...
**** Except the SuperStar theme really isn't a variation of the regular Mario theme.
** ''Sonic the Hedgehog 2'' did it best with the Super Sonic theme - music that tells you immediately that all bets are off.
** [[CaptainGamer This troper]] never stopped believing in Sonic after the theme for the final boss fight in ''Sonic Adventure 2''. He figured that they were going to pull the same garbage they did for the last half of the last boss in the previous game, but he was pleasantly surprised. [[spoiler: A big lizard is pulling a ginormous space station down to Earth to destroy it. As the fight wears on, you all begin to catch fire as you enter the atmosphere. What music do they use? Generic apocalypse music? No! You get pumped up with the full lyrical version of the same theme you've been hearing in menus this entire time! It's a big reminder that you're a way-past cool hedgehog and a heel-faced ultimate life form! Kick that lizard's space-station-shaped ass!]]
* Inverted in ''FinalFantasyVII'': A FlashBack to the BigBad's deteriorating mental state is accompanied by a few, looping malevolent chords. When he snaps, they extend and turn out to be the opening of his {{leitmotif}}.
** Not to mention the full-on OminousLatinChanting excellence of the final boss fight.
* When the main plot of ''ChronoTrigger'' starts up, they even let you bask in the theme music during enemy encounters.
** Also, characters' personal themes. [[http://www.youtube.com/watch?v=wTBb1OBYA_I Frog]] is particularly notable for this.
** Magus has a theme song that's awesome enough when your party is fighting him. However, if you happen to have him in your party when fighting the BonusBoss, [[spoiler:his mother]], he personally taunts his enemy and replaces the normal boss song with his own.
* Gig, [[OmnicidalManiac Omnicidal]] HeroicSociopath of ''{{Soul Nomad and the World Eaters}}'', has ''three'' theme songs. Consequently, he has three different stages of ThemeMusicPowerUp depending on which one's used, ranging from "you'll receive a [[DeadpanSnarker verbal smackdown]]" to "you're DeaderThanDead, and so's your ThrowAwayCountry AndYourLittleDogToo".
* In the ''[[NintendoWars Advance Wars 2/DS/Days of Ruin]]'', when a CO Power is used, the normal CO theme will be replaced by a heavy metal tune depending on the CO's faction.
** Some of the effects last until the next day/turn however, even though the theme is replaced by your respective enemy theme during their turns. Weather effects caused by CO powers can even last up to 3 days.
* An observed property of the upcoming game ''Fable II'' is that the more rhythmically you kick ass, the more awesome the BGM becomes.
** ''{{The Legend of Zelda}}: The Wind Waker'' is like this too.
* ''StarFox'' has Star Wolf's theme which remain pretty much the same (just with different instruments) throughout the series. You can't have a Star Wolf theme without Star Wolf team after all!
** Including a Mariachi Band in ''Super Smash Bros. Brawl''.
* ''SuperRobotWars'' uses this by ''default''. The music that plays during any unit's Attack animation is often it's series theme song. Same for the non-BadassNormal characters in the OriginalGeneration games, until the remake gave everybody their own. In all SRW games, they will also play the trope completely straight at appropriate moments in the plot, and will play an entire game's theme song when some ''serious'' beatdown is about to commence. Through the Alpha and OG series', Elzam Branstein's "Trombe!" is so BadAss, overrides almost all other theme music (even bosses), and results in much ass-kicking. Particularly from Alpha 3 onwards, there is the option to change the unit's battle music, with exceptions (such as "Goldion Hammer" and "Goldion Crusher", which only play during their attacks -- their BadAss attacks). In addition, the Sound Force from Macross 7 literally defeat enemies by singing at them -- and can also power up your other units with their music.
** Though, of course, that was rather the ''point'' of Sound Force. Up to and including powering the WaveMotionGun of the show by the end.
** The spin-off game ''Mugen no Frontier'' also uses this liberally: while the normal battle themes are randomly selected from 4 different possibilities depending on who's in the party, the character-specific theme starts playing whenever someone uses one of their special attacks.
** SRW manages to take this to a true extreme in ''Alpha 3'' when a song composed as a collaboration between [[SuperDimensionFortressMacross Minamy]] and Basara (in the story, at least) actually saves the day in [[spoiler: the final stage, by galvanizing the heroes against a wave of malice that comes from the series' ultimate BigBad.]] It's no coincidence that the song was created in ReaLife by JAMProject for that game.
** Sorry, I can't hear you over the sound of how '''''TROMBE!''''' I am.
** Interesting to note, "Trombe!" was ''not'' the first instance of theme song override in the series. In Alpha Gaiden at least, certain units had "super attacks" that would trigger a different song. [[GundamX "Satellite Cannon"]] and [[TurnAGundam "Dark History"]] were not programmed to have a lower priority than boss songs.
* Speaking of song overridings, ''DynastyWarriors'' have Lu Bu, which Elzam seems to be an {{Expy}} of. And finally, in SamuraiWarriors, there's Honda Tadakatsu for the man of theme song overriding. Note that the music only overrides the 'default' music (it varies based on the situation) when a player is within proximity of either, and of course that this only applies when they're opposing NPCs.
* In the [[CrowningMomentOfAwesome best scene]] in ''SuperSmashBros. Brawl'''s Subspace Emissary, after [[spoiler:Ganondorf and Bowser's gigantic Subspace Battleship shoots down the heroe's recovered Halberd, the heroes escape in their personal fighters to the ThemeMusicPowerUp.]] The music being [[OminousLatinChanting Dramatic Latin Chanting]] doesn't hurt.
* {{Boss battle}}s in ''{{Skies of Arcadia}}'' are accompanied by music that changes according to how well the player is doing. If the player's party has taken a lot of damage, the music is ominous and fractured; if the player is only a few turns from victory, it's upbeat and triumphant.
* The final boss battle in ''{{Persona 3}}'' is accompanied by a remix of ''Burn My Dread'', the game's theme tune. It's appropriate for this trope because [[spoiler:as the battle progresses, the Main Character [[SpiritBomb powers up his final ability]]]].
** Pretty much all the music in Persona 3 was awesome, but ''every'' version of ''Burn My Dread'' has the ability to either [[CrowningMusicOfAwesome rock you in the face]] or [[PlayerPunch punch you in the soul]]. The version in the final battle is incredibly tense, but also uplifting, with the slow rise of the chorus in the background and the solid, rhythmic hip-hop lead vocals creating this eternal escalator of pumped-upness. [[spoiler:And once you've played that scene, you'll never be able to hear it without [[CrowningMomentOfHeartwarming hearing Shinji helping you out]].]]
** The boss battle against TheDragon, and true ([[ScriptedBattle non-scripted]]) [[spoiler:FinalBattle]], is fought at the sound of "The Battle For Everyone's Souls" --a [[CrowningMusicOfAwesome glorious power-rock remix]] of the LeitMotif for the ''entire'' ''Persona'' series, "The Prayer For Everyone's Souls."
* In ''[[PhantasyStar Phantasy Star III]]'', the world map theme adds instruments and background to the main melody as more characters join your party. However, if the main character of the generation falls in combat, a much more tense and negative tune plays until said character is resurrected.
* This occurs at least once in each chapter of ''{{Live A Live}}'', usually using that particular chapter's battle music. A notable example is during the Mecha chapter's giant robot Buriki Daioh (whose theme music is acknowledged by an NPC saying "Start the music!" whenever the player tries to activate it). Also notable is that the game's main theme is used as the battle music for the final chapter, making nearly every battle a Theme Music Power Up.
** Also inverted in one chapter. [[spoiler:Whenever you play as [[TheWoobie Oersted and somehing awful happens to him]], he has a flashback of sorts and a loud droning noise is heard. By the end of the chapter where [[FallenHero he reanounces humanity and becomes the demon king Odio]], the droning returns, but eventually becomes a song. The song name? "The Demon King Odio," which has been used frequently in the game up to this point as the boss themes..]]
* Musical motifs from Exdeath's already evil and imposing theme in ''FinalFantasyV'' are used in his (even more awesome, in this troper's opinion) personal battle theme.
** During an optional boss fight near the end of the game, a certain song starts playing when it becomes apparent that the party can't win. The song is [[spoiler:Gilgamesh's theme song, Clash on the Big Bridge]], and sure enough he shows up to save the day.
* In ''Age of Mythology'', when the player's units attack an opponent's major buildings (Town Center, Palace, etc.) the music switches to a more stirring track.
* ''GrandTheftAuto''.
* In ''ThunderForce 5'', as you fly into space you encounter a replica of the ship you flew in ThunderForce 4 as a boss, accompanied by an (even more) awesome remix of the [[PowerOfRock heavy metal theme tune]] of ''ThunderForce 4'' (although this could be considered an inversion, considering its a ThemeMusicPowerUp for your foe).
* The ''CaptainAmerica'' and ''TheAvengers'' video game from the 16-bit era would play a cool Super-Hero type music when the level's boss was starting to lose.
* Played for laughs in ''MonkeyIsland 2'', when Guybrush swinging heroically to grab a chest prompts the IndianaJones theme tune. Then it's quickly subverted as Guybrush is left hanging from the rope and the music meekly fades out.
* In the arcade game ''[[FateStayNight Fate/unlimited codes]]'', when Archer gets to the "Yet, these hands will never hold anything" part of his chant, the regular background music cuts off and [[spoiler:"Emiya"]] kicks in. Unlimited Blade Works ownage follows.
* It's difficult to say whether Kratos' theme music in ''{{God of War}}'' is this or a particularly bloody version of MickeyMousing. Either way, it's awesome on spoons.
* In ''SpaceInvaders Extreme'', picking up a powerup [[VariableMix remixes the music into something louder and more intense]] for the duration of your powerup, and the music becomes even more epic if you go into [[LimitBreak Fever Time]].
* The final boss battle of ''LaMulana'' begins with normal-sounding boss music...which gets replaced by a remix of the Surface music, "Good Night Mom," in the boss's subsequent forms.
** ThisTroper thought it was an interesting touch on the developers' part that all of the boss themes in the game open with the same chord sequence, with some remixing between each theme... ''except'' for the theme for the final boss's true form, which instead shares it's first few notes with an alternate version of the main ruins theme that only plays the first time you enter the ruins.
* In ''CaveStory'' the battle with [[spoiler:[[PerfectRunFinalBoss Ballos]]]] has three different songs. His first form is accompanied by "Gravity," the normal boss music. Then when you reach his second form, the music switches over to "Eyes of Flame," which is usually reserved for more dangerous bosses. Finally, his third and fourth forms come with a side of "Last Battle," the background music to the battle with the Undead Core.
* In ''FinalFantasyIV'', when BigBad Zeromus has all but obliterated the party, the Elder of Mysidia clears his throat, asks all the former party members for help, and [[CrowningMomentOfAwesome "Final Fantasy", the theme song for the entire series (also known as "Prologue") plays]]. Cue the SpiritBomb that revives the party to full fighting strength.
* The FinalBattle of ''{{Okami}}''. The protagonist: Amaterasu, ''Sun Goddess''. The enemy: [[spoiler: Yami, Lord of Eternal Darkness]]. The name of the song: "The Sun Rises." Yeah, the FinalBoss doesn't stand a chance.
* In the game ''GodHand'', the song that plays in the first level, the western-style one is an awesome surf song called "Gene's Rock-A-Bye". Whenever Gene unleashes his God Hand, a much faster version of "Gene's Rock-A-Bye", called "Broncobuster" plays, even drowning out the themes of bosses he's fighting. Even Azel, who has the Devil Hand and his own Theme Music Power Up (from "Devil May Sly" to "Duel Storm") can't win against "Broncobuster".
* Grand Papillon (AKA Joachim Valentine) from ''ShadowHearts'': Covenant plays this semi-straight several times throughout the game, and parodies it in one scene. [[spoiler: During his first fight with Veronica, though not actually the first time you meet her in the game, Joachim is beaten around rather badly until Yuma throws his trademark mask to him. he crawls toward the mask and puts it on. Cue dramatic theme music and a lensflare, after which he proceeds to win the battle without breaking a sweat.]] The parody comes from the fact that the mask in no way helps him -- it's all in his head.
* The ''Space Channel 5'' games also feature this trope. In the first one at the end, when Ulala is fighting [[spoiler:Blank]], the music starts with a small, acapella version of the game's theme song "Mexican Flyer". The better Ulala does in the battle, the more voices join in with the singing. As she gets closer to winning, even real instruments start to play, finally culminating in a thick and triumphant rendition of "Mexican Flyer" as Ulala defeats the BigBad.
** Similarly, the final battle of the second game, ''Space Channel 5, Part 2'' features Ulala fighting against the new BigBad named Purge. The song that plays there is called "Connected Hearts" and is also a triumphant rendition of "Mexican Flyer", complete with the characters singing ''lyrics'' to it!
* Play with the Spartans in ''SidMeiersAlphaCentauri'', and every time your troops are fighting you'll hear an absolutely badass heavy metal theme.
* ''{{Rise of Nations}}'' replaces the usual ethnic rhythms with military fanfares every time your troops are kicking some enemy ass.
* As well as ''{{Command and Conquer}}: Generals''.
** While you can choose the music playing in the earlier ''Command and Conquer'', in ''Tiberian Sun: Firestorm'', when Cabal activated his last line of defense, a huge and powerful HumongousMecha, the song "Slave To The System" immediately plays unless you switch off the music. This applies for both GDI and NOD versions of the mission.
** Also in ''Red Alert 3'', the background music immediately changes when the player's unit is engaging the enemy in battle (and likewise changed again when the battle ends).
* ''[[DefJamSeries Def Jam: Icon]]'' is the literal embodiment of this trope. When two players fight, they each choose a song. Whomever is winning the fight will have "their" background music playing (and the background shimmies and dances to its beat). Certain areas of the level explode during bass hits, and the fighters actually control the music by making DJ scratching motions in the air to wound their opponent. [[http://www.youtube.com/watch?v=0iapGFosF_0 See how it works here, though the lyrics are NSFW.]]
* ''Wangan Midnight Maximum Tune'' marks the introduction of a major character into an arc-ending race with his or her {{Leitmotif}}.
* Keeping up with the ''Final Fantasy'' references, the last true boss of ''FinalFantasyX'' is heralded by a massively muscled arm clawing up to a platform -- and much more importantly, metal guitar.
** The "Challenge" soundtrack really comes into its own as a TMPU in the way it builds up in the cutscene in The Beyond and its peak when the fight against [[spoiler:Yunalesca]] finally begins.
* In ''{{Shadow of the Colossus}}'', the music is usually a mournful, slow-moving tune when you start fighting a colossus, but when you grab onto the thing and prepare to stab, the music swells into a louder, (usually) faster, and more awesome song that certainly fits the theme of you stabbing a thing well over 10 times your size to death. [[spoiler:And when you realize you're pulling a NiceJobBreakingItHero, the music turns bitterly ironic.]]
** Link gets one of these in TheLegendOfZelda Twilight Princess whenever he gets in the position to actually hurt the boss.
* In ''EliteBeatAgents'', the agents fight off against music-hating aliens by getting everybody in the world to dance to an ''[[CrowningMusicOfAwesome absolutely epic]]'' cover of The Rolling Stones' ''Jumping Jack Flash''. In fact, the entire game (as well as the Ouendan series it's based on) revolves around this.
* In ''AceCombat Zero'', whenever something particularly awesome happens the latin guitar from the final boss fight kicks in for a short duration. And of course there is [[CrowningMusicOfAwesome that]] final boss music.
* In the original ''Persona'', during battles where a new party member is introduced, the game uses a special battle theme called "Awakening". In these battles, the character(s) in question go from being regular high school students to [[MagicKnight full blown Magic Knights]].
* The original ''Star Soldier'' ShootEmUp for the NES changes the music when you power up...and in a later remake for the PS2, GCN, and PSP a rock remix of the power up theme plays. AWESOME.
* ''[[{{Persona4}} Persona 4]]'' has music for the FinalBoss that [[VariableMix starts out slow and ominous, then gradually picks up as you wear down the boss]]. The last stage of the music is an instrumental arrangement of the main battle theme, ''Reach Out to the Truth''.
* In ''[[{{GuiltyGear}} Guilty Gear 2: Overture]]'' whenever one player gains a clear upper hand their character's theme music plays.
** Also, special music plays when certain characters face off in a Master vs. Master battle.
* The ''{{Wild ARMs}}'' series, with the exception of the first and third games, have a tendency to have the game's theme song serve as the final boss's BGM. Possibly among the most awesome usages of this trope; ''{{Wild ARMs 2}}'' and ''{{Wild ARMs 4}}'' in particular use ThePowerOfFriendship and a SpiritBomb attack completely shamelessly in the course of the fight, which when combined with the [[CrowningMusic/VideoGames incredible songs]] makes for [[CrowningMomentOfAwesome moments of total awesome.]]
* ''TheWorldEndsWithYou''. You're about to face down the final boss alone, leaving you practically powerless. Suddenly, your friends [[MyNameIsInigoMontoya decide to stop being unconscious and help out]]. Cue the SurrealThemeTune.
* In the console version of ''BlazBlue'', if a player performs Bang Shishigami's Furinkazan super move, the music suddenly changes to a brand-new song by [[JAMProject Hironobu Kageyama]] called "Omae no Tetsui ni Kugi wo Ute". It's an over-the-top song about how much of a HotBlooded {{Badass}} Bang is. And it is ''[[CrowningMusicOfAwesome awesome.]]''
** '''''BANG BANG BANG [[http://www.youtube.com/watch?v=FYKPmkOF-z8 BAAAAANG!!!]]'''''
* ''{{Disgaea}}'' is fond of this. An interesting point is Kurtis' awesome [[spoiler:return]], which makes the [[CrowningMusicOfAwesome music]] his theme by default.
** Also, the anime switches to an instrumental version of Lord Laharl's Hymn whenever the Prince gets angry. But that's nothing next to what [[spoiler:The earth SDF]] does when ''their'' theme music is first played.
* ''TalesOfTheAbyss'' has this used ''against'' the party in the optional Arena battle with four previous Tales characters; at first, the game is playing [[http://www.youtube.com/watch?v=cxH5zaTQHzk "Everlasting Fight,"]] which is a medley of previous Tales battle themes. If you don't defeat them fast enough, Reid will activate Aurora Wall...
-->'''Reid:''' ''We will not'' '''''LOSE!!'''''
::...revive any of his fallen party members, deal tons of damage to you, and a remix of [[http://www.youtube.com/watch?v=W70Rr2wFWQ8 "Eternal Mind"]] suddenly starts up. This is about when any average player goes "OhCrap."
* ''BatenKaitos Origins'': the true final battle starts with your team knocked silly, but [[spoiler: your friends from Malpercio in the past sequences come to help]], your team is revived, and "Le Ali Del Principio" starts playing -- the same music from when Geena first unfolded her wings. Naturally, a nine-year-old girl singing Italtian gives you the strength to triumph.
* The final boss of Devil Summoner 2: RaidouKuzunohaVsKingAbaddon, comes in three stages. The first stage has a unique battle theme, the second is recycled from earlier, but the third plays ''Raidou's'' theme, as a nice reminder of just how epic he is.

* [[TheAdventuresOfDrMcNinja DoctorMcNinja]] has to -- I repeat, ''has to'' sing along to the ''{{Ghostbusters}}'' theme in order to empower himself to do battle with ethereal beings.
** Not the lyrics though, just the tune: "Dada, Dadadada!"
[[/folder]]

[[folder:Western Animation]]
* The heroes of most shows in [[{{DCAU}} the animated DCU]]. In one episode of ''JusticeLeagueUnlimited'', Green Arrow even sang along to his theme as he kicked butt.
** In the {{Justice League}} episode "Hereafter", Batman fights Kalibak while a fairly quiet orchestral version of the 1966 TV theme song plays in the background.
** The Joker in ''{{Batman the Animated Series}}'' would hum his own theme music on occasion.
* A particularly awesome example comes from the ''BatmanBeyond'' episode "Disappearing Inque". Terry gets kidnapped by the villainess Inque, and she threatens to kill kim unless Bruce shows up. Later on, we see a large figure in a trench coat walking towards Inque... which turns out to be Bruce, in a massive Batman mech suit. The moment he starts wailing on her, an orchestrated version of the Batman theme from ''Batman the Animated Series'' starts playing.
** Something similar happens in another episode where Bruce, rejuvenated by a couple dips into a Lazarus Pit, fights side-by-side with Terry, with the ''BTAS'' theme going, except it's electric guitars instead of trumpets soaring.
* The ''{{Popeye}}'' cartoons, with Popeye's spinach-induced theme music, make this OlderThanTelevision.
* Parodied in the ''SouthPark'' episode "Towelie", as whenever the titular Towelie got high, Popeye's theme music played and Towelie became dumber than he already was.
* Most of ''KimPossible'''s flipping, fighting, and swinging is accompanied by a guitar-and-strings action {{leitmotif}} that's re-used in every episode. A few of the recurring villains also get their own theme music; the mini-episode "Adventures in Rufus-Sitting" features a four-way fight in which the soundtrack changes several times in the space of a few minutes to reflect whichever combatant currently has the upper hand. Check out [[http://www.veoh.com/videos/v9543065rcW5gPy this clip]].
* The ''{{Futurama}}'' {{OVA}} "Bender's Big Score" has the climactic battle with the theme playing the background.
* The fifth season finale of ''TeenTitans'' (not counting the ''last''-last episode) has a particularly stirring version of the show's theme playing during the final battle with the Brotherhood of Evil.
* Played at the climax of "The Drill" in ''AvatarTheLastAirbender'', as Aang hands Azula one of her few outright defeats in the series.
** Not to mention during the [[WhamEpisode Season 2 Finale]], any time Aang enters the Avatar State, and most especially during the climactic fight with Fire Lord Ozai. One of the coolest versions ever actually plays during the end credits after the series wraps up; the theme song was actually one of the first things that drew this troper to the show.
** Side note: Aang's [[{{Leitmotif}} theme song]] is actually a remix of the main theme.
*** Same motif is played during a flashback episode featuring Aang's predecessor, Avatar Roku, describing the amazing power he became master over when he learned all the bending arts.
* The original ''{{Transformers}}'' movie has "The Touch" by Stan Bush, most memorably played during a FoeTossingCharge by Optimus Prime, and also when the Matrix of Leadership is opened near the end of the movie. Some fans theorize that Megatron and the Decepticons also received a power-up from "Instruments of Destruction" during the attack on the shuttle where they [[DroppedABridgeOnHim killed Prowl, Brawn, Ratchet, Irohhide in about ten seconds]]. One can probably make an argument for "Dare to be Stupid" for the Junkions.** Optimus Prime of ''TransformersGeneration1'' still has "The Touch" in "The Return Of Optimus Prime" when he opens up the Matrix of Leadership to wipe out the HatePlague. His eventual successor, [[TransformersSuperGodMasterforce Ginrai]], gets the rather cool "Don't Cry".
** ''TransformersCybertron'' gave us the instrumental song "Our Ally". Ass-kicking ensues whenever it plays. It has been favorably compared with The Touch. It most notably accompanied [[spoiler: [[{{CrowningMoment/Transformers}} Optimus Prime running Galvatron through]]]].
* In ''{{Thundercats}}'', Lion-O got to trigger his own theme music when he powered up the Sword of Omens. Ta-ta-TAA! And not only did he get to start kicking ass, but all the other Thundercats, no matter where or how captured/restrained they were, could see the Lion-signal, hear the roar, and naturally break free.
* In the first two season finales of ''Series/{{X-Men}}'', a particularly rousing take on the show's theme backs up the heroes in the final battle. Then the third season started applying it to roughly every other fight they got into, and it kind of lost its potency.
* Any time you hear the ''{{Ghostbusters}}'' theme start playing in the background of a scene in ''TheRealGhostbusters'', you just know things are about to get good.
* Likewise, [[HeMan He-Man]]'s [[ByThePowerOfGreyskull transformation sequences]] are always accompanied by stirring theme music, no matter what incarnation you're referring to.
** Even in the Live Action movie, where He-Man has no alternate persona and therefore doesn't have a transformation sequence, gets a musically enhanced Power Up when necessary. [[http://uk.youtube.com/watch?v=7ceERPc3pyw He Has The Power!]]
* In ''CodeLyoko'', William gains a personnal theme music in Season 4 once he turns evil. It follows him in every of his subsequent apparitions, which are generally the most intense fights in the show. (He isn't always victorious, though.)
* Any time that [[CaptainPlanetAndThePlaneteers Captain Planet]] is summoned. Most of the time it's the title theme, but there are a couple of other music cues that are equally awesome.
* In the first episode of the '80s ''[[WesternAnimation/TeenageMutantNinjaTurtles1987 Ninja Turtles]]'' toon, the turtles discover that the Foot Ninja they're fighting [[RoboticReveal are actually]] [[MechaMooks robots]], and the theme music starts up as they proceed to go to town on them.
