8 AOA Kpop Group Members: Complete Profile Guide (2025 Update)

The release of "Miniskirt" in 2014 marked a turning point for AOA Kpop group, catapulting them to nationwide success and their first music show win on Inkigayo. Following this breakthrough, their 2015 hit "Heart Attack" became one of the year's most downloaded songs.

AOA (group) debuted on August 9, 2012, under FNC Entertainment with eight members: Choa, Jimin, Yuna, Youkyung, Hyejeong, Mina, Seolhyun, and Chanmi. During their active years, the group released 18 albums and achieved 10 music show wins, with their "Miniskirt" music video garnering over 109 million views.

However, following a series of events including member departures and controversies, the group's activities slowed down after 2019. By 2024, all AOA members had left FNC Entertainment, effectively marking the end of one of K-pop's notable girl groups.

AOA's Original Formation

FNC Entertainment introduced AOA (Ace of Angels) with a distinctive "transformer" concept in July 2012. The group's name represented their celestial concept, with members portrayed as angels descending to Earth to share their musical talents.

AOA's Debut Concept

The group's angel concept extended beyond mere imagery, as each member received a unique angel name. Specifically, seven members were designated as "full angels": Seolhyunari, Choaya, Hyejeong.Linus, Chanmi T.T, Yunaria, Minaring, and leader Jiminel. Moreover, Youkyung held the special status of "half-angel/half-mortal," creating the distinctive "7+1" group structure.

Initial Member Lineup

FNC Entertainment unveiled the members through individual teaser photos from July 16 to 23, 2012, in this sequence:

Seolhyun
Choa
Hyejeong
Chanmi (now known as Dohwa)
Yuna
Mina
Jimin
Youkyung

Dual Concept: Dance and Band

Initially, AOA operated with a unique dual-promotion strategy. The group functioned as both a seven-member dance unit and a five-member band unit. In the band configuration, members showcased their instrumental talents: Jimin played guitar, harmonica, and piano, Choa handled guitar, Yuna managed keyboard, Mina played bass, and Youkyung commanded the drums. This innovative approach stemmed from FNC Entertainment's background in managing bands like CNBLUE and FTISLAND.

The group's debut single album "Angel's Story" launched on July 30, 2012, featuring the title track "ELVIS". Subsequently, AOA made their official stage debut on M! Countdown on August 9, 2012.

Sub-unit Activities

Throughout their career, AOA diversified their musical presence through three distinct sub-units, each showcasing different aspects of the group's talents.

AOA Black's Musical Style

AOA Black emerged as the group's first official sub-unit in 2013, consisting of five members: Choa, Jimin, Yuna, Mina, and Youkyung. The band unit demonstrated their instrumental prowess through several notable performances:

Released debut single "Moya" on July 26, 2013, achieving 171,475 digital downloads and 2,692 physical album sales
Performed band version of "Get Out" on KM's Music Triangle in October 2014
Maintained activities until Youkyung's departure in October 2016

AOA Cream Formation

FNC Entertainment unveiled AOA Cream in early 2016, featuring Yuna, Hyejeong, and Chanmi. The sub-unit aimed to spotlight members who had received less attention in the main group. Their debut single "I'm Jelly Baby," released on February 12, 2016, showcased a bright, pop-oriented sound and reached number 26 on the Korean Gaon charts.

AOA White Activities

In contrast to the other sub-units, AOA White functioned as a non-promotional dance unit. Consisting of Chanmi, Seolhyun, and Hyejeong, this sub-unit particularly focused on variety show appearances. Although AOA White never released official music, they maintained their presence through dance performances and entertainment programs.

The sub-units represented different facets of AOA's versatility, with AOA Black highlighting their band capabilities, AOA Cream showcasing their pop sensibilities, and AOA White emphasizing their dance and entertainment skills. Nevertheless, after 2016, sub-unit activities gradually decreased as the group focused more on full-group promotions.

The song peaked at No. 11 on Gaon Digital Chart and No. 8 on Billboard K-Pop Hot 100. Correspondingly, their follow-up single "Short Hair" achieved even greater success, reaching No. 4 on Gaon Weekly Album Chart.

Heart Attack Era Success

The group's popularity soared in 2015 with "Heart Attack," which became their biggest hit. Thus, the song achieved unprecedented streaming success, becoming the only AOA track to surpass 100 million cumulative streams. Their third mini-album demonstrated remarkable longevity, maintaining its position in the top 100 charts throughout the year.

Japanese Market Entry

In October 2014, AOA expanded their reach by releasing a Japanese version of "Miniskirt". Ultimately, they released their first full-length Japanese album, "Ace of Angels," in October 2015, featuring eight previous Japanese singles and three new songs. The group's international presence strengthened through performances at KCON 2015 in Los Angeles and New York. Their Japanese singles consistently performed well, with "Like a Cat" reaching No. 6 on Oricon Daily Chart and claiming the top spot at Tower Records Shibuya on its release day.
