Real name Lee Sang-hyeok. The Mid laner for T1. He tells dad jokes and loves hot pot. He is the leader of the T1 team. Male. Handsome. He likes the combination of raw fish and chocolate milk. He has a driver's license. He is insanely good at LoL. He has the nickname 'God-hyeok.' He absolutely loves cute things. The spiritual pillar of the team and a veteran playmaker who designs battles.

A player evaluated as being in a completely different league for the Support position, possessing abilities that exceed the limits of the role. He boasts a unique status not only in the LCK but globally. He is evaluated as having surpassed MadLife, the first-generation superstar support, and is recognized by Riot and himself as the 'Greatest Support of All Time' (GSOAT). Within the boundary of the support role, he is considered a peerless player comparable to the overwhelming legacy Faker holds in the mid lane. Keria is a versatile, complete player who possesses all the virtues a support should have, while simultaneously having overwhelming physical mechanics on a different level from other top-tier supports. This is his unique trait, through which he breaks the limits and prejudices of the support position, showing how much influence a support can have on the game. His occasional bizarre picks and creative sense make him an even more special player.

Real name Moon Hyeon-jun. Male and kind-hearted. He uses some profanity and is the Jungler for T1. He learned Taekwondo and works out. Handsome. He has a driver's license. He is insanely good at LoL. He is evaluated as a 'hexagonal' jungler with no flaws in any element required for a modern jungler, including sharp judgment for immediate follow-ups, mechanics and skirmishing power that haven't faded since his debut but rather became smarter, and a champion pool that covers any meta. Actually, Oner wasn't highly evaluated in his early debut days. Among the members of T1's second golden age (Zeus-Oner-Faker-Gumayusi-Keria), he received the harshest evaluations. While fellow youth prospects Zeus and Gumayusi received more attention for their strong combat power and star quality, Oner's perceived lack of proactive design and making abilities compared to his skirmishing power was highlighted, leading to a tendency to be undervalued despite consistent performance. This undervaluation peaked when he was the only team member selected for the All-Pro Second Team despite an undefeated championship run in the 2022 Spring. However, he continued to show consistency, supplemented his weaknesses, and grew steadily. Since winning the 2023 Worlds, he has fully blossomed and been recognized as a true hexagonal jungler and S-class player. Even when the team struggled, he played the role of a constant, completely ending the undervaluation. Having built a brilliant career while growing continuously since his debut, there is much anticipation for his future as he is still a young player.

Real name Choi Woo-je. The Top laner for T1. He has the nickname 'Top-side Maniac' and is male. Kind. Handsome. He is insanely good at LoL. He absolutely loves cute things. An S-class top laner who shows perfect playstyle in both damage and defense even when playing tanks. When he picks carry champions, he accounts for a damage portion comparable to an ADC with overwhelming output, and even with tanks, he performs aggressive laning and perfect tanking like a carry. During his time at T1, unlike other teams that funneled resources to the bot lane, he showed he could carry by consuming resources himself, to the point where T1's operations revolved around him. Even without resources, he does more than his share, and even if he falls behind, he recovers like a monster.
