Mackiah

Mackiah is a Korean-Australian singer, rapper, and AMPERS&ONE member signed to FNC Entertainment. He debuted with AMPERS&ONE on November 15, 2023 and has become part of the group's multilingual identity and youthful performance core. During the April 2026 Definition comeback, Mackiah was specifically credited in press coverage as one of the members who contributed lyrics across all six tracks on the EP. That detail matters because it places him inside the making of the release, not just its promotion cycle. For a group still defining its sound in a crowded rookie field, Mackiah's writing credit gives his early profile more substance than a standard member introduction.
