About

Bang Sung-hyeon, better known by his competitive online alias JJonak, established himself as a dominant force in the professional esports landscape. Rising to prominence as a skilled competitive Overwatch player, his early career trajectory was marked by exceptional mechanical precision and game sense that separated him from his peers in the South Korean gaming community.

In 2018, Bang reached a major career milestone by signing with the New York Excelsior (NYXL) for the inaugural season of the Overwatch League. During his tenure with the team, he secured two stage titles and achieved individual acclaim by winning the league’s regular season most valuable player award in 2018. His exceptional technical proficiency and impact on the competition even prompted game developers to honor him with a special, unique in-game skin.

Following the conclusion of the 2021 season, Bang transitioned from the NYXL to sign with the Seoul Dynasty. Although health issues required him to step away from the Dynasty prior to the start of the 2022 season, his lasting influence on the game and his legacy as an elite competitor remain firmly established within the history of professional esports.
