ZEROBASEONE

ZEROBASEONE, also written ZB1, is a boy group under WAKEONE that was assembled through Mnet's survival show Boys Planet and debuted in July 2023. Their records are built on huge physical sales, including six straight million-selling releases, and they have placed on the Billboard 200 with their first full album. Their early work leaned on bright, youthful pop, while the 2026 five-member era moves toward a cleaner, more grown-up dance-pop and contemporary R&B sound. U.S. fans follow them for the strong Billboard showings, the survival-show backstory, and the high-profile reshaping of the group in 2026. Their fandom is called ZEROSE.

How they formed

The group was formed on Mnet's Boys Planet, where 98 trainees from several countries competed and viewers voted nine winners into the final lineup. The show was notable for putting a foreign-born trainee, Zhang Hao, in first place. The nine members came from South Korea, China and Canada, and several had earlier idol, dancer or survival-show experience. The name signals nine people starting from zero and becoming one. They debuted on July 10, 2023 with the mini album YOUTH IN THE SHADE and lead single "In Bloom", after passing one million pre-orders before release. The project contract with WakeOne ran about two years and eight months, which set up the lineup change in 2026.
