10 K-Pop Groups Who Debuted With No Minor Members

Recently, it seems like rookie idols are getting younger and younger. While groups have debuted with members as young as 14 or 15 years old for generations, several of today’s new K-Pop group line-ups are primarily made up of members aged 18 or under.

With debates around minors debuting in the K-Pop industry waging on over the past year, there’s no doubt that groups don’t need younger members to succeed. Just take a look at these 10.

1. BLACKPINK

BLACKPINK debuted on August 8, 2016, with dual singles “BOOMBAYAH” and “Whistle,” and they’ve been dominating the charts since day one.

When their debut EP Square One was released, the youngest member, Lisa, was 19 years old.

2. MONSTA X

MONSTA X released their debut song, “Trespass,” on May 14, 2015. Since then, they’ve risen to become one of the most loved boy groups of the third generation.
