BuZz (Yu Byung-chul) — Valorant Professional Player Settings and Gear
About BuZz
Yu 'BuZz' Byung-chul was the captain and emotional leader of DRX during their legendary VCT Champions 2022 Grand Final run, where the Korean roster came agonizingly close to winning the biggest trophy in Valorant before falling to LOUD in one of the most memorable Grand Finals the game has ever produced. That Champions run — which saw DRX defeat several favored teams through superior teamwork and clutch individual performances — established BuZz as one of the most respected leaders in Korean Valorant. His playing style has evolved throughout his career from a primary Jett duelist to a more flexible role that incorporates sentinel and initiator agents, a transition that showcases his willingness to adapt his game for team success rather than clinging to the glory of the star role. On T1, BuZz brings the championship experience and leadership maturity that the organization's Valorant project needs, serving as both a tactical contributor and a stabilizing veteran presence for younger teammates. His mechanical foundations remain strong despite the role transition — BuZz can still produce star-level performances when called upon, making him one of the most complete players in the Pacific region. The DRX era that BuZz captained is remembered as one of the great what-if stories in Valorant: a team that played the most beautiful Valorant in the world but fell just short of the ultimate prize.
