T1 Bot Kim “Peyz” Su-hwan is T1's bot laner and a three-time LCK champion, signed through 2028 as Gumayusi's replacement. He became the youngest bot laner ever to win an LCK title at 17; his mouse model and client DPI have never been published.
Peyz has no published settings data — neither his mouse model nor client DPI and slider values appear in any setting sheet or event setup. He plays for T1 at 1920×1080 as the team's bot laner, and this profile records only what can be verified rather than estimating the rest.
Peyz's career has already turned over twice in four years. He came through Gen.G's academy, won everything in Korea at 17 and 18, was traded to JD Gaming in the LPL as part of the Ruler deal, spent a season in a collapsing roster, and then returned to the LCK in November 2025 as T1's replacement for Gumayusi on a contract through 2028. He is 19 and has already been through more roster churn than most veterans.
The unusual part of the résumé is the JD Gaming year: a player with three LCK titles and an MSI crown went to the LPL, won nothing, and missed Worlds 2025 entirely. Coming back to a T1 seat is the correction.
Peyz is a positioning-first bot laner rather than a highlight-reel one. His Gen.G years were built on stable laning, reliable teamfight output and a champion pool broad enough that opponents could not ban him out — Gen.G's 2023 and 2024 drafts frequently revolved around securing him a safe lane rather than a winning one. The criticism that follows him is the mirror of the same trait: in series where Gen.G needed an individual spark, he was not the one generating it.
The comparison that defines Peyz's 2026 is Gumayusi — the player he replaced — and behind it, the question of what T1 actually needed from its bot lane.
Gumayusi left T1 as a three-time world champion and S15 finals MVP; Peyz arrives with three LCK titles and an MSI crown but no Worlds trophy. T1's gamble is that a younger, structurally similar player can be integrated into the same system — the contract length (through 2028) suggests they are treating it as a long-term build.
Peyz's public advice is about bot-lane fundamentals rather than mechanics — the part of the role that does not show up in highlight clips.
It was a trade, not a benching. At the end of 2024 Gen.G wanted Ruler back, and Ruler was under contract at JD Gaming in the LPL — so Peyz went the other way to JDG in a swap. He had just spent two seasons as Gen.G's starting bot laner, winning every LCK split in 2023 plus MSI 2024, and left right after Gen.G's Worlds 2024 semifinal exit to T1.
Because the Ruler swap put him there. He spent 2025 with JD Gaming, whose season unravelled around him — the roster changed support, top lane and coaching staff repeatedly, and JDG finished without a trophy and missed Worlds 2025 entirely. Peyz's individual level held up; the team's did not.
Because Gumayusi left. After T1 won Worlds 2025 with Gumayusi as finals MVP, the two sides could not agree on a new contract, and T1 moved fast — signing Peyz on 19 November 2025 to a deal running through 2028. It is a long commitment for a 19-year-old, and it put him into a bottom lane with Keria, widely rated the most mechanically gifted support in the game.
Yes, as the starting bot laner for 2026 — but the comparison is unkind and he knows it. Gumayusi left T1 as a three-time world champion and the S15 finals MVP. Peyz arrives with three LCK titles, MSI 2024 and the LCK Rookie of the Year award, but zero Worlds titles, and he is four years younger than the man he replaced.
Two that stand out: he is the youngest bot laner ever to win an LCK title, taking the 2023 Spring playoffs at 17, and he recorded 28 kills in a single game at an international event — one of the highest single-game kill totals in international play. He has also been named to the LCK First All-Pro team twice.
No verified peripheral data is available for Peyz — neither the mouse model nor client DPI and slider values have been published in a settings sheet or event setup. This page leaves the fields blank rather than guessing, which is the standing rule for every profile in the ProAiming player database.
Every profile in the ProAiming player database is cross-checked against published setting sheets and event setups before it appears, and re-checked before each major event. Hardware, resolution and any client-slider values must come from a verifiable source; anything a player has never published is left blank rather than estimated. Where a value changes mid-season, the most recent verified figure is the one shown.
