A powerhouse performer in K-pop whose intense stage presence and animalistic dance style have redefined the energy of a boy group idol.
Choi San, born in 1999 in Namhae, South Korea, is the explosive center of the group ATEEZ. Initially a trainee known more for his bright personality than technical polish, he underwent a legendary transformation, drilling his dancing relentlessly to become one of K-pop's most watchable performers. His style is physically demanding and narratively rich, often embodying characters from ATEEZ's elaborate storylines with a feral, captivating intensity. Offstage, known as a gentle and caring member, this duality fuels his appeal. San doesn't just sing and dance; he consumes stages, making him a pivotal figure in ATEEZ's rapid ascent from a promising rookie team to global concert hall fillers.
1997–2012

San was born in 1999, placing them squarely in the Generation Z. The events that shaped this generation — social media, climate anxiety, and a pandemic — shaped the world they entered and the choices available to them.
