Music: AOA

One of the fewer photos of all eight "angels" note 

A Korean Pop Music idol Girl Group who debuted under FNC Entertainment in August 2012. Full name being Ace of Angels, they are well-known for being a "transformer group" - part band, part dance. AOA promotes as a combination of two units: five in the band unit (officially called AOA Black), and seven in the dance unit. Together as AOA they focus on pop-rock and acoustic pop to accommodate both the units' strengths.

Despite simultaneously promoting both units being their original premise, the last time they actually released music together was in 2012 with Wanna Be - afterward, the two units also got their own noteworthy promotions. AOA Black brought the group their first number one on several music charts with Moya which showed off their prowess as a band; and the dance-unit single Miniskirt was nominated on a music show once on Inkigayo - and there the group got their first win.

They are a possible Base Breaker due to leaving their band unit on hiatus during 2014 in favour of their dance unit and more pop friendly music, not to mention demoting drummer Youkyung and leaving her to the sidelines by trying to make the dance unit the only AOA, which brings many unfortunate implications. Nevertheless, the whole group have won many fans for their multi-talent, Ear Worm songs, likeable personalities and impressive visuals.

Do not confuse with Age of Apocalypse the comic book, or The Axis Of Awesome the band, which both use the same initials. Also do not confuse with the Hong Kong pop twin duo with the same name, who are unfortunately overshadowed and hard to search up.
  • Album Intro Track:
    • Miniskirt has "Gonna Get Your Heart", a short Choa solo.
    • Short Hair has "Fantasy", sung by the non-rappers.
    • Like A Cat has the self-titled "AOA" which is sung by Choa and Yuna (with a bit of Jimin in the background) to a gentle guitar.
  • Angelic Beauty: Invoked in their backstory for the angel concept they debuted with, where them being angels explains why they're so attractive. In particular is "Hyejeong.Linus - the most beautiful of all angels".
  • Ascended Extra:
    • Youkyung once drummed for her teacher and famous Korean guitarist Kim Se Hwang's showcase predebut.
    • Seolhyun was the lead girl in FT Island's "Severely" MV before making her debut in AOA.
  • Auto-Tune: Surprisingly present in the otherwise relaxed song "Joa Yo!". Jimin and Chanmi's raps are autotuned and so is Mina's singing.
  • Bare Your Midriff: Their stage outfits do this a lot. It was most prominent in the "Confused" era whey they often wore crop tops that showed their waists.
  • Bath Kick: Hyejeong gives one to show off her legs in her Bathtub Scene in the "Miniskirt" MV.
  • Bathtub Scene: Hyejeong gets this and a Shower Scene scene in the "Miniskirt" MV, and consecutively too for no reason other than for fanservice - she first takes a shower (clothed) before going on to her bubble bath (unclothed), complete with Censor Suds and a Bath Kick.
  • Beauty, Brains and Brawn: AOA White's angel backstory at debut invoked this - Hyejeong.Linus is the most beautiful of all angels, Seolhyunari is the brain among the angels and Chanmi T.T loves to dance.
  • Big Little Brother: Seolhyun is the second youngest yet also the 2nd tallest (along with Youkyung) at 167cm, possibly taller, and can often be seen towering over her older members. To a less extent, Chanmi is the youngest but is still part of the taller half of the group at 166cm.
  • Biker Babe: Chanmi rides a motorbike in her spy catsuit near the beginning the Japanese MV of "Like a Cat".
  • Blatant Lies: Even Hyejeong and Jimin's faces screamed this when the latter made her "dating" confession: when Hyejeong asked who it was, she gestured to the camera (the audience) and cheerfully replied, "With all of you guys!" Cue silence.
  • Blonde, Brunette, Redhead: Several times since members are prone to dying their hair. For example in the "Elvis" era, Youkyung was blonde, Hyejeong and Choa had orange hair and everyone else were brunettes.
  • Boastful Rap: Common in their songs, courtesy of main rapper Jimin. One example is the ever-so-repeated "Like A Cat" line, "I'm good I'm hot I'm fresh I'm fly!"
  • Boyish Short Hair:
    • Averted with Choa's hair "Miniskirt" era onwards, as it was the shortest haircut out of everyone's at the time yet her feminine personality is the polar opposite of most examples.
    • Youkyung debuted with short hair and has the tomboy image invoked with her, but she started growing it out at the end of 2013 (and Chanmi think she's prettier this way).
  • Breakout Character: AOA's dance unit on their own is just a subunit yet have become more active than the actual group itself since 2014.
  • Breakup Song: Quite a few - the ones that were promoted are "Get Out", "Moya" and "Short Hair"; the first two call out on the ex-boyfriend for being annoying and a jerk, while "Short Hair" talks of letting go of the past including a break-up.
  • Censor Suds: Bubbles conveniently cover Hyejeong's body to give her some modesty in her Bathtub Scene in the "Miniskirt" MV.
  • Cloud Cuckoo Lander:
    • Choa and Jimin have been pointed out a lot to be very quirky at times, whether it be spacing out or saying/doing something completely random.
    • Hyejeong was voted the quirkiest member due to her odd habits when she's nervous (eg. her inability to stand still). Indeed, now and then she's caught in rather odd positions.
  • The Cutie:
    • Jimin, who's frequently thought to be the maknae despite being 2nd oldest. She looks young, is very cheerful and can have a childish personality when messing around - she's even been compared to famous child-star Choo Sarang. Members agree she has the most aegyo (cuteness) in the group. Her feisty personality also averts this though.
    • Choa, who is the oldest and is known for it yet has a youthful appearance, bubbly and sweet personality and Cloud Cuckoo Lander tendencies.
    • Mina, as Choa discussed when she said she often calls her Cutie Pie. She is quite small, young-looking and clumsy, and sometimes mistaken as the maknae too (she's the 3rd youngest overall, and AOA Black's maknae). She often averts this though when her snarker personality shows.
  • A Day in the Limelight:
    • The two units often get to solely showcase their own skills, especially when they got individual promotions after Wanna Be:
      • AOA Black focuses on 5 members and their instrumental skills, and they sometimes perform covers as just the band eg. the "Price Tag" cover. Also, Moya is an AOA Black-only single and its promotions were solely focused on them hence also finally gave Youkyung well-deserved spotlight and full activities. Then there's the "Elvis" MV band-only version which shows these 5 girls rocking it out to the song.
      • The dance unit focuses on 7 members and their dance skills, and they sometimes do their own dance covers. Their solo promotions started off like this as the songs solely focused on their charms as dancers, however the trope has gradually stopped coming into effect as they've become more prominent than the whole group itself since 2014.
    • AOA White, which focuses on the dance-only members, sometimes do mini dance projects (dance tutorials, Gangnam Style special stage, their Crazy In Love cover) and it's been said getting their own promotions in the future is a possibility.
    • Their Angels' Cams on their official YouTube account give most members including the lesser-known members some individual attention, especially earlier ones which helped fans get to know them better. For example, one is of Yuna playing keyboard and singing, and another is mostly just Hyejeong and Mina staring at the camera.
    • Hyejeong was a guest-singer in Phantom's "Seoul Lonely" lives for first week of promotions. Her lines were unfortunately prerecorded and not live, but nevertheless gave her the rare opportunity be a main singer.
  • Demoted to Extra: AOA Black was supposed to be the dance unit's equal but FNC has demoted them mid-2013 onwards to focus on the latter. Hence, Youkyung has gone from an important full-time member to a hardly-appearing "half-member", and AOA having an 8th member is unfortunately nearly always glossed over even by FNC and official media sources.
  • Distaff Counterpart: The band unit to their older labelmates and famous idol bands FT Island and CN Blue.
    • In particular is Choa to FT Island vocalist Hongki, for both being power vocalists and having similar tones. She even released her own version of his drama OST "Words I Couldn't Say". FNC went along with this by having the two of them sing the OST together at the December 2014 FNC Kingdom concert.
  • Dress Rehearsal Video:
    • All their music videos have both units performing like they would to an actual audience.
    • The "Moya" MV averts this in the end when the band hijacks the stage and performs for the audience.
  • Elegant Classical Musician: AOA Black, whose visuals are praised and are admired even more when they play their respective instruments. In particular is Yuna who plays the most elegant instrument out of all of them (the piano) and whose visuals are highly praised by members. It mostly shows in her two solo videos of her singing and playing a ballad version of CN Blue's "I'm Sorry" and "The First Noel".
  • Embarrassing Nickname: Their "angel names" listed in Stage Name which they debuted with to go with their angel concept. Everyone was dumbfounded, jokes were made and members expressed their embarrassment when introducing themselves with these. The names have notably been ditched ever since.
  • Even the Girls Want Her: A Discussed Trope in their 2014 Taiwanese interview where Jimin and Youkyung were picked as the members with the most female fans due to being charismatic and cool when performing in the band.
  • The Face:
    • Seolhyun's official position - she's one of the most well-known members, often made front and center and given the most attention and promotion by FNC, and her solo activities tend to help get AOA's name out there.
    • Choa and Jimin are quite active in interviews and variety which make themselves stand out and help stick the group together. It helps they have a good chunk of lines in their songs and stand out in terms of stage presence when performing.
  • Face on the Cover: All their covers show the members, though Wanna Be is the only one that has close ups of their faces.
  • Fangirl:
  • Fanservice: Lots lots lots of this, whether it be wearing short-shorts or dancing provocative moves. Special mention goes to their Eye Practice dance unit practice videos, which give specific close-ups of each member during their part and giving viewers the chance to be stared at intensely by each member.
  • The Fashionista: Jimin's voted by members to be the biggest one in the group, as she really enjoys coordinating and planning her outfits.
  • Football Fight Song: The dance unit has one for the 2014 World Cup, called "Spread Your Wings of Victory".
  • Funny Background Event: Prone to this, especially in their Angel Cam videos.
    • In Jimin's one in the dressing room for their "Get Out" band stage, Youkyung who is sitting in the background does some silly things like laughing at/with Jimin and making random hand gestures towards the camera.
    • In Hyejeong/Mina's one, you can see Seolhyun walk by, stop and start dancing to "Get Out". The girls then (unintentionally, maybe) blocked her from the view.
    • On Weekly Idol when Hyejeong was demonstrating her cutesy and sexy dances, Mina could be seen ignoring her and simply indulging in her fried chicken (courtesy of the show staff).
  • Fun with Acronyms: Ace of Angels.
  • Gratuitous English:
    • Many in their songs have... interesting English for no particular reason.
      • "Elbis jirit jirit elbis, tell me tell me your love!" "Everybody wink, wink!"
      • The B-side "Love Is Only You", which repeats the title. A lot.
      • "Paradise in your eyes, heaven is in your eyes."
    • Jimin's debut teaser, where she was shown with a lute and the caption said "Jiminel, who plays the rute".
  • Genki Girl: Jimin was voted the most playful member by the group in a Taiwanese interview, being energetic and loves to joke around. It also shows in group performances where she shows the most energy and stage presence.
  • Harp of Femininity: Was part of Mina's angel backstory picture at debut which had her gracefully playing a harp with the caption "Minaring who plays the harp all the time". Of course, it was just symbolic of her bass.
  • Hired for Their Looks: Seolhyun and Hyejeong were scouted at modelling events and are the official Face and Visual of the group respectively.
  • Hotter and Sexier: They've always oozed sexiness in some way but FNC and members themselves say "Confused" was the era where the dance unit first started doing sexy concepts.
  • Huge Schoolgirl: Hyejeong is the tallest at 172cmnote . Seolhyun and Youkyung are the next tallest at 167cm, though possibly taller. Their heights are more praised than anything else and they're not unhappy with it, in contrast to most examples. They often wear non-heeled/shorter-heeled shoes even if the others are in heels, and they normally still meet or surpass their height. Youkyung's height is made even more obvious when she's with just AOA Black where all the short girls are.
  • Important Haircut: The whole point of "Short Hair", as it's symbolic of letting go of the past. In the lyrics' case, namely a bad break up. In the MV's case, namely a bad day; after facing difficulty at work, everyone in the dance unit visits Choa's salon to let off some steam and get bobcuts (though funnily enough Jimin's and Yuna's hair were already short to begin with and so didn't change post-haircut).
  • Incredibly Long Note:
    • Being the main vocalist, Choa sings at least one long note in many of their songs. Their promoted songs that have one from her are "Get Out", "Confused" and "Miniskirt".
    • Yuna sings some long notes now and then due to being the lead vocalist. Examples include "Miniskirt" and "Time".
  • Irony: The first teaser photo of AOA Black's "Moya" promotions was them dressed in white and set against a white background.
  • Jack-of-All-Trades: Being able to play instruments, sing/rap and dance is part of their concept, and applies to members of both units (as well as Seolhyun who's officially only the dancer/face but can play piano too). AOA Black members have also written 20 songs together, though sadly none have been shown yet. In particular:
    • Jimin, besides rapping, can speak Chinese, compose songs and write lyrics (in particular she actually writes all of AOA's raps) and play guitar along with some basics of harmonica and piano.
    • On top of her well-acclaimed vocals, Choa first learned some basic drums and keyboard before picking up guitar to train for AOA Black. She's also qualified in Aviation Business Administration which she studied in college.
    • Yuna is said to be the most well-rounded member as she is one of the more proficient band members due to playing piano since young, is the lead vocalist and the best dancer out of the band.
  • The Klutz: Mina has fallen/tripped the most of out the others in the dance performances. She also barely kept up in their first Random Dance Play segment of "Weekly Idol" and was jokingly asked by the MCs if she was a new member.
  • The Leader:
    • Jimin's official position and is thus often the spokesman, takes charge in many situations and sometimes writes their lyrics.
    • Choa is the secondary leader due to being the maternal figure and oldest. She's sometimes mistaken as the official one due to her age and role as the main vocalist.
  • Light Feminine and Dark Feminine:
    • AOA White vs AOA Black; if the names don't speak for themselves already, AOA White is the more "graceful" subunit due to focusing solely on dancing, while AOA Black is more fierce and focuses on rock band music.
    • The dance unit vs AOA Black, where again the dance unit (mostly in their early years) play with the "sweet and innocent" image while the band sports the more devilish and mischievous look.
  • Little Big Brother: Choa and Jimin who are the oldest yet shortest at less than 160cm. Choa was not pleased when she was made to stand in between the tall yet younger members Hyejeong and Seolhyun in a Weekly Idol episode specifically to show off their height differences.
  • Male Gaze:
    • Their MVs and choreographies since debut but it went Up to Eleven from "Confused" onwards to go with the sexy concepts. In particular is the creepy and blatant camera focus on their shaking butts in the "Get Out" and "Miniskirt" MVs.
    • Most of the fancams since debut of the dance unit are not shy on focusing on certain body parts at certain provocative movements, which can get squicky considering it also happened when Seolhyun and Chanmi were underaged.
  • Meaningful Name: Some of the seemingly random angels name do apparently have meaning behind them according to members:
    • Yunaria - "angel that is as beautiful as flowers"
    • Jiminiel - the L signifies her as the leader
    • Chanmi.T.T - the two T's signify her cuteness as the maknae
    • Minaring - it means a halo which is shining brightly on an angelís head
    • Seolhyunari - the "ari" means "charming" and the name as a whole means "Seolhyun virus"
  • Motor Mouth: Jimin's raps are a mouthful and very fast, especially in "Elvis" and "Moya".
  • Multicolored Hair:
    • Youkyung occasionally has quite a few colourful extensions, especially in her "Moya" teaser.
    • Jimin's hair was dip-dyed at debut, first with green/blue and later with pink.
    • Seolhyun had some blonde highlights along with her brown hair during the "Like A Cat" era.
  • The Musical:
    • Choa was in the Korean High School Musical as Gabriella along with labelmate FT Island's Jaejin, and was meant to be in the Zorro musical but was taken out for personal reasons.
    • Yuna was in the Korean Summer Snow musical which took place in Japan, alongside labelmate FT Island's Seunghyun.
  • New Sound Album: Their "Confused" single is a complete 180 from previous songs, going from an interesting pop-rock and band-acoustic sound to a safe retro pop sound that is very common in kpop. Slightly a given since this is only the dance unit in contrast to the full group, however even the AOA Black-only "Moya" single has influences of their full group music while still maintaining their own flare.
  • Never Trust a Trailer: The first video teaser for "Confused" had the dance unit wearing white while innocent looking at the camera and eventually sitting together wearing blindfolds, all to gentle ballad music. The actual song and MV? A textbook pop song with the girls dancing provocatively in black outfits most of the time. The singing heard in the teaser was kept in though, and the footage of them in white is briefly shown in the beginning but with no signs of the blindfolds.
  • Not So Stoic: Discussed Trope in regards in Youkyung in Episode 8 of Open Up! AOA when she, Choa and Chanmi visit a psychology cafe. Chanmi mentions that she first thought Youkyung was too cold and quiet but she found her to be really warm after rooming with her and Choa says she is more emotional than she lets on.
  • Older Than They Look: Jimin and Mina, often dubbed the fake maknaes. The actual maknae Chanmi is a 1996er. The other two were born in 1991 and 1993 respectively. It helps they're short and play up the aegyo.
  • One-Letter Name: Youkyung's angel name Y.
  • Power Ballad: AOA Black's "Without You" and the dance unit's "Tears Falling" are rock ballads. Choa's OST for the drama The Bride of the Century is also a gentle and tear-jerking ballad.
  • Put on a Bus: Youkyung and Seolhyun/Hyejeong/Chanmi have this done to them depending on which unit is promoting (and of course there's the units themselves). In particular:
    • Youkyung has this done to her the most since the dance unit is more active and she isn't given any other activities; end of 2013 onwards she is on an indefinite hiatus, to fans' chagrin. Music college is FNC's main reason for her absence, but it's quite invalid since she's been attending college before "Moya" promotions'' which shows she's capable of studying while actively promoting. Fans rejoice whenever she makes a rare appearance.
    • AOA Black promotions of any kind have not been done since mid-2013 to pave way for the dance unit, and they've been given few performances ever since. FNC's excuse was to wait until the dance unit brought in enough popularity to support another comeback, which Miniskirt fulfilled. Fast-forward to 9 months later - and still no signs of them promoting again, although they did reappear briefly by starting off their performance medley for the 2014 MBC Gayo Daejejun which has brought some hope.
    • Seolhyun is already prone to this often enough due to her busy acting schedules, but she was also put on a longer one during Miniskirt promotions due to her injured knee, though she still participated in many CFs. It was extended again when she injured the same knee.
  • The Quiet One: Invoked in their music with Youkyung who doesn't sing nor rap (her drumming on the other hand...), and she speaks the least in interviews (by choice or not), often only saying her introduction. In an FNC magazine issue depicting the girls' dorm life Youkyung is described to be someone who "doesn't like to talk".
  • Retcon: At debut, AOA was always stated as an 8-member group with Youkyung considered a member like everyone else, and both units considered equal. Once the fame of Miniskirt kicked in, FNC had Youkyung shafted to the sidelines and since then they merely treat her as some random back up member while treating AOA as a 7-member group, and since then they acknowledge AOA Black as nothing more than a non-serious act. Members and media have gone along with this sadly. Despite girls' statements in "Like a Cat" era that FNC wanted to wait for the dance unit to become more popular before bringing AOA Black back, whether or not this is true remains to be seen.
  • The Reveal: A very surprising one at the end of the "Moya" MV - the guy that cheated on Choa isn't the handsome guy like the MV heavily implied, but the comedian!
  • Self Plagiarism:
    • All their choreographies recycle a lot of moves. Even the highlights of Miniskirt and Short Hair are almost the same (shaking the hip/butt with hands together, just done from different views). It should be noted that FNC initially just trained instrumentalists.
    • Their songs after "Confused" have gotten this critique which is to be expected when working with infamous self-plagiarism producer Brave Brothers. "Miniskirt" is a rehash of all his recent previous songs and "Short Hair" is often dubbed as Miniskirt 2.0 due to sounding nearly identical (they both even have an "oooh" part, and both go with their similar hip-shaking moves on top of that!).
  • She Cleans Up Nicely: Youkyung's has the tomboy image invoked on her thus usually sticks to pants and shorts, so much fuss was made when she joined the others for a CF photoshoot (their trope picture is part of it) and wore a miniskirt/stockings outfit hence a more "sexy" look.
  • She's Got Legs: All members whose legs are often shown off in photoshoots and performances. Hyejeong's are praised the most within the group as she's the tallest thus automatically have the longest legs which has gotten her the status as the group's sexiest member/member with the best body.
  • Shower Scene: Hyejeong gets this and a Bathtub Scene in the "Miniskirt" MV, purely for fanservice. She first takes the shower (clothed) before moving on to the bath.
  • Shout-Out:
    • Their "Get Out" MV has all the members cosplaying as several female characters to promote female empowerment: Choa as Elle Woods, Jimin as Mathilda, Yuna as Lara Croft, Youkyung as Leeloo, Hyejeong as The Bride, Mina as Holly Golightly, Seolhyun as Juliet (the 1968 version with Olivia Hussey), and Chanmi as Hermione.
    • In the "Moya" MV, the band that AOA Black kicks off stage parodies FT Island's "I Wish" and CN Blue's "I'm A Loner" - the main vocalist even parodies Hongki for "I Wish", sporting the same tiara headband and imitating his shoulder dance.
  • Show Some Leg: Most of their outfits aren't shy about showing some legs. Special mention to the miniskirt-zipping move in the "Miniskirt" dance which shows even more leg.
  • Shrinking Violet:
    • Zig-Zagged with Youkyung who is quieter than the others and appears shy when the camera is on her, yet has expressed a strong desire to receive spotlight and be recognised a skillful drummer and has shown a friendly and talkative side when actually given the chance - which is rare.
    • Hyejeong describes herself as someone who used to be shy and insecure until she picked up cheerleading and modelling, which apparently gave her a confidence boost and got rid of said shy side.
  • Singer Namedrop: "A to the, O to the, uh huh, A A!" from Moya, amongst many other songs.
  • Sixth Ranger:
    • In the "Elvis" MV Youkyung joins everyone else midway, falling out of nowhere in the room they're in. They accept her in the group and she jams with fellow band members afterward.
    • Averted yet a common misconception with the group due to their confusing member/unit set-up with Youkyung and AOA White members turning up at seemingly random points depending on the unit that's promoting.
    • Juniel played with this, joking about becoming the 9th member in a group photo of her with them. A possible nod to rumours that she was also going to be a member despite already being a soloist.
  • Spiritual Successor: AOA Black are seen as the 2nd Scandal as both are Asian girl bands that stand out in the sea of girl groups in their respective industries.
  • Spoken Word in Music: "Joa Yo!" has Seolhyun's spoken English lines at the beginning: "Blue sky, summer breeze, I love it!"
  • Spy Catsuit: The dance unit sport some variations in their "Like A Cat" MV where they are cat burglars, and it was mostly what they wore for the performances in that era.
  • Stage Name:
    • Their angel names are derivatives of their real names and are as follows - Jiminel, Choaya, Minaring, Yunaria, Seolhyunari, Hyejeong.Linus, Chanmi T.T. and Y. They are no longer used in their introductions and profiles.
    • Youkyung was under the stage name Gaon when she was Sponge Band's drummer.
  • Surprisingly Good Foreign Language: Jimin spent a few years studying in China with her cousin so she knows conversational Chinese.
  • Team Dad: Jimin (the 2nd oldest and leader), as discussed by members. They say she guides the group, is the strictest and has high expectations of the other members.
  • Team Mom: Choa, as discussed by members. She's the oldest and cooks for everyone and said to take care of them when they're down.
  • Title Track: "Moya" and "Miniskirt" of their respective single-albums, "Short Hair" and "Like A Cat" of their respective mini-albums.
  • Tomboy: Invoked with Youkyung's styling; she debuted with and stuck to Boyish Short Hair for a while and and is styled less femininely than the others - for example for "Elvis" she wore an Elvis-style shirt/pants outfit while others wore Elvis-style dresses, and in an FNC Kingdom concert she wore a shirt/shorts of similar colours to their dresses/skirts. She's also been named the "quiet big brother" of the group and plays drums which is considered a masculine instrument.
  • Training from Hell:
    • Learning bass was this for Mina, to the point of her crying from hurting her fingers.
    • Jimin getting Carpal Tunnel syndrome predebut was due to practising guitar too much, and she had to get surgery.
    • It's been mentioned that, like Jimin, Youkyung hurt her hands from practising the drums a lot for the band and also got surgery.
  • Translated Cover Version: Some songs were translated to Japanese for Japan promotions such as "Miniskirt" and "Like A Cat".
  • Truck Driver's Gear Change: The key changes in the last choruses in "Love Is Only You", "Get Out" and "Moya".
  • Unperson: From the "Miniskirt" (or even "Confused") era onwards, not only has FNC been trying to make the dance unit the main AOA, they also often remove mentions of Youkyung from most of their media and avoid calling her/listing her as a member at all.
  • Unplugged Version: There are official videos on their YouTube channel of Choa, Yuna and Jimin singing acoustic versions of "Miniskirt", "Short Hair" and "Like A Cat".
  • Up to Eleven: 8 members, or as FNC first stated, "7 + 1 members".
  • Vocal Tag Team:
    • Choa and Yuna aka the main and lead vocalists. While it's a given in AOA Black since a band normally only have 2 vocals at best, it even happens in the dance unit as they usually sing 75% of a song.
    • Rap Tag Team variant with Jimin, Mina and Chanmi, though it often varies between Jimin/Mina and Jimin/Chanmi. Sometimes averted when Jimin gets the good 80% of the rap.
  • The Voiceless: A variant with Youkyung; she's only in the band-unit and prefers to just drum, and so she's the only member who's not heard singing nor rapping (though she rapped in one of Sponge Band's songs).
  • Who Wears Short Shorts?: Majority of their stage attire use short-shorts so as to invoke She's Got Legs. Were only absent altogether for "Miniskirt", because the dance unit wore... well, miniskirts (and dresses).
