BX

BX (비엑스), born Lee Byung-gon (이병곤), gave CIX its steadiest center. As the group's leader and rap anchor, he helped define the moody, low-slung tone that separated CIX from brighter fourth-generation peers, then held that identity together through lineup changes and a long final stretch that closed with Thunder Fever.

His pre-debut profile already ran deeper than a typical rookie introduction. Survival-show exposure put BX in front of fans early, but CIX is where his control became legible: precise live delivery, a calmer stage presence, and the kind of leadership that mattered even more after Bae Jin-young exited in 2024.

That is also why BX's 2026 departure from C9 Entertainment lands as more than contract news. It closes the first full chapter of an artist who often carried CIX's tension, discipline, and sense of scale in the same verse.

Fans Also Ask

Who is BX in CIX?
BX is the stage name of Lee Byung-gon, the leader and main rapper of CIX. He debuted with the group in 2019 under C9 Entertainment and became one of the members most associated with CIX's darker performance identity, especially in the four-member era that followed Bae Jin-young's 2024 exit.
Was BX on survival shows before CIX?
Yes. BX built early recognition through the Korean survival-show circuit before CIX debuted. That pre-debut exposure gave him one of the most visible trainee profiles in the lineup, but his reputation inside CIX ultimately came from his leadership, low-register delivery, and reliable control in live performances.
Is BX leaving C9 Entertainment?
Yes. C9 Entertainment said BX's exclusive contract ends on April 30, 2026 as the company halts CIX's group activities. The announcement effectively closes BX's first CIX chapter, even as the agency says it hopes the group's brand and music can reconnect with fans in some form later.
