Lore & Background

Oner's path to the main roster started in 2020 within the developmental ranks of T1 Academy. After turning 17 on January 31, 2021, he made his LCK debut just weeks later against Liiv SANDBOX. While his initial 2021 Spring Split involved limited playing time, his promotion to a starting role marked a turning point. By the 2022 Spring Split, Oner was instrumental in T1 achieving an undefeated 18–0 regular season record, a historic first for the LCK. This dominance carried them to their first title under his leadership. The years that followed saw consistent pressure; after losing the 2023 LCK Spring and Summer finals to Gen.G, Oner guided T1 to their fourth World Championship in November 2023 with a decisive 3–0 victory over Weibo Gaming.
