Originally a sub-unit of the idol group Music/SakuraGakuin, [=BabyMetal=] (also stylized as BABYMETAL) was formed by the members of the Heavy Music Club of Sakura Gakuin, under the concept of a fusion of "heavy metal and idol music". [=BabyMetal=] released their first single "BABYMETAL Kiba of Akiba" in March 2012, reaching the 3rd place in the Oricon indie charts and number one in the Tower Records Shibuya weekly indie ranking. However, it wasn't until they released their second single, [[http://www.youtube.com/watch?v=2IzR_ClTE8Y "Headbanger!!"]], that they became popular outside of Japan. The video went viral quickly and the sub-unit managed to become a stand-alone group. In 2014 they did a 2-day Budokan concert[[note]]10000 spectators each day[[/note]] and released their eponymous first album. The video for ''Gimme Chocolate!!'' was released just before the Budokan concert and promptly went viral, to the extent that non-Japanese [[UsefulNotes/MainstreamMedia mainstream media]] picked it up.

At the Budokan concert it was announced that the first chapter of the Metal Resistance was over, and BABYMETAL would continue their training overseas. Dates in Paris, Cologne, Knebworth[[note]][=SoniSphere=] 2015[[/note]], London and Los Angeles followed, along with opening slots for Music/LadyGaga. These went well enough that further dates in New York and London[[note]]this time in the Brixton Academy[[/note]] were hurriedly arranged. During the Brixton show a new song ''Road of Resistance'' was performed[[note]]this was the first time a new song had been unveiled outside Japan[[/note]], and it was announced that BABYMETAL would return for the Metal Resistance Part III...

* ''BABYMETAL x Kiba of Akiba'' (2012)
* ''Headbanger!!'' (2012)
* ''Ijime, Dame, Zettai'' (2013, the group's first major release)
* ''Megitsune'' (2013)
* BABYMETAL (2014)

!!Tropes that apply to [=BabyMetal=]
* TheAce
** Suzuka for singing. The creator of the group had been looking for some years for someone to train up as a metal idol. Then he saw Suzuka performing in Karen Girl's (age 11) and the rest is history.
** Yui for dancing. Although the other two are no slouches either.
** Moa for crowd engagement.
* AscendedExtra: They're even more popular than their parent group, Music/SakuraGakuin.
* AudienceParticipationSong: Judging by Website/YouTube videos, most songs during concerts have audience participation segments. Oh, and festival performances of ''Ijime, Dame, Zettai'' encourage a Wall of Death...
* BadassAdorable: A large part of the appeal.
* BadassCape: During live performances of ''Akatsuki'' (a Suzuka solo).
* BilingualBonus: Many songs contain the occasional English word or phrase, but the most notable example is their concert opener, Babymetal Death - a deliberate bilingual pun, since what they're actually shouting is Babymetal Desu (I am Babymetal), but the pronunciation of "Desu" is similar to the English "Death" - a fact not lost on the promoters.
* ButNowIMustGo: Averted. Sakura Gakuin only accepts members under 15 years old, and when the current members reach this age, they must graduate. When Suzuka became 15, she left the main group, but the management made [=BabyMetal=] a separate unit, thus allowing them to be active. Yui and Moa graduated in 2015, so now all members are independent to Sakura Gakuin.
* ChildProdigy: Yui and Moa were talented enough to join Sakura Gakuin at the age of 11 (and produce ''Doki Doki☆Morning'' one year later). And before Sakura Gakuin, Suzuka was in a group called Karen Girl's doing the opening theme of ''Manga/ZettaiKarenChildren''. And that's not counting the other stuff they've done...
* CreepyCoolCrosses: They use it a lot. Special mention goes to Suzuka's 16th birthday, when she was ''crucified''.
* DarkerAndEdgier: Compared to other idol groups.
* EarlyInstallmentWeirdness: Their first song, ''Doki Doki☆Morning'', had a more distinct "idol-like" sound than their following songs.
** ''Doki Doki☆Morning'' appeared to have a very low budget (and most of that probably went on the music). The costumes used in the video were made up from a combination of the girl's clothes (and some from a staff member for Suzuka). The next video (as uploaded to Youtube) for ''Ii ne!'' shows them in the same costumes. The third video for ''Head Bangya!!'' sees them use the costumes that are recognizably related to their established look.
* [[ExcitedShowTitle Excited Song Title!]]: Their song ''Ii ne!''.
** Also ''Head Bangya!!'' (or ''Head Bangeeeeerrrrr!!!!!'')
** ''Gimme Chocolate!!''
* FourIsDeath: The Black Babymetal song "4 no Uta" ("Song 4" or "Song of 4", a song that uses a lot of wordplay surrounding 4's readings in Japanese) seems to refute this with a line in the chorus stating that 4 is not synonymous with death.
* GirlishPigtails: Moa and Yui's usual hairstyle. Suzuka started out having these too.
* HeWhoMustNotBeSeen: The musicians during their early years wore skeleton costumes in the music videos and while appearing in public. Except in ''Megitsune''... where they wear long black wigs and masks. In reality, they were just faking playing to a backing track.
** HeWhoMustNotBeHeard: When the musicians themselves (including the producer) get interviews, all they do on-screen is mumble and subtitles of what they're actually trying to say are shown.
** Averted in concerts from 2013 onwards - they now have a live band wearing white robes and facepaint, composed of members of former Japanese rock / metal groups. There's a semi-regular lineup, although members will get swapped out if they have availability issues.
* HimeCut: When they let down their hair. Suzuka plays it the straightest (literally too), and she's actually done so in certain music videos such as ''Megitsune''.
* IAmSong: "Babymetal Death" is an extreme example, since pretty much the only lyrics are the group introducing themselves.
* IconicOutfit: Their outfits from ''Headbanger!!'', featured in the picture to the right. Now used in most live concerts.
** Also the early era musicians' skeleton costumes / loose white robes of the current musicians.
* IdolSinger
* {{Kawaiiko}}: Moa and Yui.
* {{Kitsune}}: The main theme of ''Megitsune''.
** The theme of the group itself, with its fox sign. They're always seen doing it, such as in the image above.
* TheLeader: Suzuka. Also the FaceOfTheBand.
* LoudnessWar: Their music is all brickwalled and almost pure clipping from start to finish. This may be an intended effect though...
* LuckyCharmsTitle: ''Doki Doki☆Morning'', ''Uki Uki ★ Midnight''.
* MindScrew: What this idol group is to metal purists. Though many of them somehow like the group...
* MohsScaleOfRockAndMetalHardness: On average, a hard 6 to a soft 7, though "Megitsune" is a borderline 8.
** "Babymetal DEATH" seems to go as far as a 9, with most of the vocals being death growls and metal screams and having nearly none of the super-happy cuteness factor a lot of their other songs have.
* NeoclassicalPunkZydecoRockabilly: Combines the hardness and energy of heavy metal with the catchiness and appeal of J-pop and a VisualKei-influenced sensibility.
* NervesOfSteel
** Karen Girl's did their final live performance at an anime festival at the Saitama Super Arena[[note]]the largest venue by far they had played, with a capacity of 20000[[/note]]. Several years later the other two group members[[note]]Ayami Muto and Yuika Shima[[/note]] related that they were both extremely nervous before their performance. Meanwhile, Suzuka was snoozing in the dressing room and had to be woken up in time to perform.
** You would expect most teenage Japanese girls to be more than a bit nervous when facing 50000 British metalheads at their first appearance in the UK[[note]][=SoniSphere=] 2014[[/note]]. If they were it was not at all obvious...
* PunctuatedForEmphasis: ''Ijime, Dame, Zettai'' (''No, More, Bullying'') is a strange example.
* RatedMForManly: The inversion of this trope is the whole point of this band.
* RedOniBlueOni: Moa and Yui to a certain extent - Moa Red, Yui Blue.
* SongStyleShift: "Iine!" has a ''[[TrapMusic Trap]]'' break near the middle, complete with hoodies, GratuitousEnglish, and Music/KanyeWest [[http://1.bp.blogspot.com/_txdFVAWpc94/TOKwqIGfagI/AAAAAAAAA4o/JMPJAXyX6xY/s640/kanye_west_daft_punk_stronger_01.jpg sunglasses.]] [[http://www.youtube.com/watch?v=qVdBBOpSoN4&t=1m33s We are completely serious.]] Apparently it's done as a TakeThat to SwagRap.
** "Uki Uki ★ Midnight" has a {{Dubstep}} break, [[http://www.youtube.com/watch?v=W-2Z_kQpdW0&t=1m36s also near the middle.]]
** "4 No Uta" also features a reggae section.
* SpellMyNameWithAnS: ''Ii ne!'' faces the same problem as ''[[Music/{{Vocaloid}} Ievan Polkka]]''. Three guesses on what that problem is and the first two don't count.
* SureLetsGoWithThat: At the beginning of the group the manager was trying to teach the members the [[WardingGestures heavy metal horns]] gesture. They misinterpreted the description and made the a 'kitsune sign' instead. The whole Fox God mythology of the group probably stems from this.
* ThatSyncingFeeling: Early live performances were mostly lipsynced, with some live vocals blended in (quite common for idol performances). Later on Suzuka did more and more live, followed by Yui and Moa. The production of the ''LIVE AT BUDOKAN'' albums (2015) makes it very easy to hear that the backing vocals are confined to a few parts of the Black Babymetal songs (mostly parts with strenuous choreography).
* TitleScream[=/=]MetalScream: ''HEADBANGEEEEEEEEER!!!''
* TomboyishPonytail: Suzuka's usual hairstyle.
* [[WidgetSeries Widget Musicians]]: Three {{Idol Singer}}s mix pop music with HeavyMetal. It works and it's... ''[[CrowningMusicOfAwesome it's totally awesome]]''. Oh, UsefulNotes/{{Japan}}...
* ZettaiRyouiki
