Ato (TRIGER)
Ato (아토 / アト) is a South Korean vocalist and the tallest member of TRIGER, standing 186cm. Accepted into DY Entertainment through auditions, his membership was announced on June 16, 2021. A former model who studied in the Model Department, Ato originally dreamed of becoming a singer and found his calling in idol performance. He has loved being in the spotlight since a young age, often performing at school festivals, and that early hunger for the stage never left him.
His role model is BTS' Jungkook. His favorite superhero is Iron Man. In TRIGER, his official color was blue and his birthday falls on April 18, making him an Aries. The vocal work he committed to across five years with TRIGER reflected the same discipline: intensive stage training layered on top of a modeling career that already demanded physical presence and visual awareness.
Teammates described Ato as well-built, proactive, and caring -- someone who lifted the group's energy with random jokes and creative ideas, always the first to break tension and ensure no one felt left behind. They called him the person who never lets things go stale, the one whose spontaneous energy kept the atmosphere alive during long tour cycles and rehearsal stretches.
After TRIGER concluded its activities on March 7, 2026, following seven years under DY Entertainment, Ato joined fellow member Roa in announcing FRAME THE X, a new six-member project under the same label. The group is set to debut in April 2026. The two carried the gratitude of the TRIGER era and the promise of delivering something stronger into what comes next.
