* ''Anime/PrincessTutu''. The whole anime is based around the power of Ballet.
** Guitar ninjas.
* The ''[[Anime/SuperDimensionFortressMacross Macross]]'' series is about The Power Of IdolSinger Music (and of [[NuclearWeaponsTaboo reaction warheads]]). It should be noted, it usually has a different justification every time; only in ''{{Macross7}}'' is singing an actual source of superdimensional energy.
** ''{{Macross 7}}'' is all about a spacefaring J-Rock band that fights giant space vampires by rocking them so hard they have orgasms (at least, [[http://www.youtube.com/watch?v=1uCciEhtzGU Sivil does]]). In [[HumongousMecha transforming fighter planes]] controlled by guitars. It works.
** One of the Space Vampires rocks out so hard [[EarthShatteringKaboom it blows up a planet]].
*** In the original ''Anime/SuperDimensionFortressMacross'', Minmei's song revealed the concept of "culture" to the [[ProudWarriorRaceGuy war-waging Zentraedi]], which caused them either to defect to protect [[NeglectfulPrecursors their creators' legacy]], or shocked them with abject terror.
**** The singer they got in for the English dub is said to have a similar effect on the audience.
*** In ''MacrossFrontier'', it's not so much the song as the passionate feelings behind it which affect the empathic Vajra, who communicate through song ([[spoiler:and across the galaxy, if the singer has the ability]]) themselves.
*** ''MacrossPlus'' sees a rare use of ThePowerOfRock for evil. Sharon Apple, a [[AiIsACrapshoot rogue AI]], uses it to mind control an entire ''city'' in the OVA and '''[[UpToEleven the entire planet Earth]]''' in TheMovie. [[spoiler:She is finally stopped when Myung [[CrowningMomentOfHeartwarming hits Isamu with her own special song that she hadn't sung in seven years]], breaking him out of Sharon's spell so he can destroy Sharon's central computer core.]]
* ''Anime/NerimaDaikonBrothers''. Pretty much the whole thing.
* Subverted by ''Anime/{{Interstella 5555}}.'' While rock itself is not that powerful, the Gold Records from an award show are powerful enough to allow a man to conquer the universe.
* ''MermaidMelodyPichiPichiPitch'' combines this with MagicMusic. Later in the series, the ''villains'' fight back with their own songs, too.
* Mic Sounders the 13th of ''GaoGaiGar'' uses rock music from discs, microphones, and a '''key-tar''' from his flying soundstage to attack, disable enemies, and power up his allies. His Disc X is actually able to [[spoiler: rip enemies apart at the ''molecular level'' or shoot a gigantic laser beam at them]].
** In ''VideoGame/SuperRobotWars W'', it can also destroy Radam trees from ''Anime/TekkamanBlade''.
** Never mind Disc F, which is apparently so potent that it takes ''two'' members of the Mic Force to play it (actually a song sung by [[JAMProject Masaki Endoh and Hironobu Kageyama]]). Mic Sounders the 13th [[CrowningMomentOfAwesomeMechaAnime does it on his own]], by unleashing [[DualWielding two extra arms to hold two microphones]]. For an encore, he plays a suspension bridge like a giant harp.
* The WaveMotionGun in ''BlackHeaven'' is powered by a heavy metal guitarist's "groove". However, it's also [[spoiler:partial to ''evil techno'']].
** It's worth noting that the original title is ''Kachou Oh-Ji'' ("Office Boss Ohji", referring to the main character). The subtitle? ''[[ExactlyWhatItSaysOnTheTin Hard Rock Save The Space]]''.
** BlackHeaven, or "The Legend of Black Heaven" is all about this. An aged, retired rocker (and later the rest of his old heavy metal band) is called back into action by a group of aliens to fight off an evil alien space empire with, you guessed it, the power of rock.
* The ''LightNovel/HaruhiSuzumiya'' [[RadioDrama Drama CD]] had four-fifths of the FiveManBand face a musical monster, which first has to be weakened by [[HollywoodToneDeaf singing badly at it]], before commencing to rock out.
* The ''Anime/ScienceNinjaTeamGatchaman'' episode "Murder Music" had Galactor capturing a rock band, drugging and forcing them to play music personally created by Sosai X. With the recordings, a special ship with super speakers plays the music at a zillion decibels to create a devastating sound wave that can drive people insane and shatter matter.
* In ''Manga/AhMyGoddess'', the demon Marller/[[SpellMyNameWithAnS Mara]] -- on top of her weakness to good luck charms -- can be forced to dance nonstop, and thus defeated, when she is exposed to Rock music.
** Similarly, Belldandy's half-demon sister Urd, who is otherwise one of the most BadAss characters in anime, can be put to sleep by the Japanese music genre of [[http://en.wikipedia.org/wiki/Enka enka]]. She hates this.
* One episode of ''KeroroGunsou'' had the team combating a "bad funk [[TheVirus virus]]" with the power of an IdolSinger trio.
* How monster users in ''BusterKeel'' power up their monsters using guitars. Usually depends on what pick is used and what music is played.
* The final battle in ''Shin KoihimeMusou'' is a war between {{Idol Singer}}s. The Chou Sisters versus an impromptu group formed from Enjutsu, Choukun and Kakuka. The war is not so much about the singers as it is [[CharmPerson controlling their fanboys]] to either take revenge or calm down. The final blow is dealt by Ryuubi and company singing an a capella version of "Ima wo Shinjite" that wins by ThePowerOfFriendship alone.
* In {{Grenadier}}, one of the Jutensen uses a miniaturized [[OminousPipeOrgan organ]] as a weapon that can project an impenetrable shield of sound, and can probably melt your insides with a riff.
* This plays a massive part in TwentiethCenturyBoys, so much so that one of the major plot points of the final arc is that of [[spoiler:Kenji uniting the rundown populace of the now CrapsackWorld and giving them courage through his protest song that is being broadcasted via pirate radio. It also serves as a way to let his friends know he is still alive, due to modified lyrics in the song]]. In the end, [[spoiler:Kenji and his song are one of the main reasons that [[BigBad Friend]] is eventually defeated]].
** One of the best examples of this trope in the series is when [[spoiler:Kenji returns after 10 volumes and 15 in story years. He shows up at a maximum security checkpoint on the outskirts of Tokyo, and is promptly surrounded by armed guards with orders not to let anyone pass through. What does he do? He simply whips out his guitar and begins singing his song, which mystifies the guards. However, the peasants in the checkpoint recognize it from the broadcasts and begin converging towards him. The guards become agitated when they notice the effect the song is having on the peasants, so they quickly shoot Kenji in the chest. Five seconds later, he's back up on his feet and singing his song right from where he left off. Just at that point, hundreds of his followers emerge from behind him and easily overwhelm the guards]]. This leads [[spoiler:Kenji]] to deliver one of the most memorable lines of the series to one of the guards.
-->[[spoiler:'''Kenji''']]: I ''said'' I'm singing a song. And when someone's singing a song [[PunctuatedForEmphasis you. Don't. Shoot them.]]
* In ''Manga/FairyTail'', the Villain Vivaldus brainwashes Juvia with a magical electric guitar by playing various solos.
* ''Anime/{{FLCL}}'' is set in a world where electric bass guitars are the most powerful objects in the universe.
* Parodied in ''Anime/BoboboboBobobo''. Denbo, Jelly Jiggler and Don Patch fight J by singing, which makes stuff in the song become real. But the songs they think up are completely ridiculous, involving things like Beta-Carotene and a 49 year old man. There's even a little [[VideoGame/DanceDanceRevolution DDR]] section. This is [[RecycledInSPACE recycled]] in the manga sequel, except that [[BrattyHalfPint Pokomi]] is the one singing.
* ''Anime/SenkiZesshouSymphogear'' is about powering your armor through singing and kicking alien ass with it. This gets even better as the casts becomes larger each season, as each and every Symphogear is a capable singer of their own right, on top of being [[NamesToKnowInAnime big names in the anime industry]].
* In ''Manga/PokemonSpecial'', Bianca plays a certain song on the guitar until Meleotta remembers Relic Song, allowing it to change Forme and fight off the flock of Vullaby attacking them.
