Nam Seong-mo

Nam Seong-mo (남성모), known as Seongmo, is one of the key rap voices inside 82MAJOR, the Great M Entertainment group pushing a harder, more street-led edge than most fourth-generation boy acts. Born on April 19, 2004, he has become central to the group's attack-heavy identity, bringing a low, direct tone that cuts through 82MAJOR's dense production.

He joined Great M Entertainment in June 2020 and trained for more than three years before 82MAJOR debuted in October 2023. That pre-debut run shows in how settled he already sounds on record. Across ON, BEAT by 82, X-82, and Silence Syndrome, Seongmo has helped define the group's rhythm-first, performance-first appeal.

His profile grew further in 2025 when he became a co-MC on Show! Champion, giving him weekly visibility beyond the usual comeback cycle. That mix of sharp stage presence and lighter broadcast energy matters. It turns Seongmo from a promising rookie rapper into one of the more recognizable faces in 82MAJOR's lineup.

Off stage, he has shared interests that make him feel less polished and more specific. He follows Premier League football closely, wants to visit England, and has hinted at personal creative work through his 419oc SoundCloud handle. The result is a profile that still feels early, but clearly not unfinished.
