ATEEZ’s first music video as a K-pop group is for the song “Pirate King,” which was released on October 24, 2018. This music video was part of their debut EP, Treasure EP.1: All to Zero, and it marked the beginning of their journey in the K-pop scene. The EP itself was quite successful, peaking at number seven on the weekly Gaon Albums Chart and selling over 23,000 copies in its first year.
