Oner LoL: Career, Champions and Worlds 2026

Oner (Mun Hyeon-jun, 문현준) is the starting jungler for T1 in Korea’s LCK and one of the best-known junglers in League of Legends (LoL). Born on 24 December 2002 in South Korea, he has played for T1 since January 2021 and was part of the roster that won Worlds in 2023, 2024 and 2025. His game is built on early pressure from fighters and divers such as Xin Zhao, Lee Sin and Vi, junglers who want to start skirmishes rather than wait for them.

Oner is winning at almost exactly the same rate as in 2025, but the shape of his games has changed. Last season he went 118–69 with a 4.43 KDA; in 2026 his win rate sits right beside that mark while his KDA has dropped, because he is dying more often and averaging slightly fewer kills and assists per game.

The other numbers explain how. He is farming more and earning more gold per minute than in 2025, and his vision per minute is clearly up from last season’s 1.5. At the same time his kill participation has fallen from the 73.1% he posted in 2025, and he is taking a slightly smaller share of T1’s damage. Read together, that is a jungler spending more of the game on farm, wards and map setup, and less of it arriving at every fight in every lane.

The season is not finished. With the LCK playoffs behind him and Worlds still to play, his game count has not yet reached last season’s total, so the per-game averages in the table can still move.

Vi and Xin Zhao carry Oner’s 2026. They are his two most played champions this year and both have won far more than they have lost on samples large enough to trust. Vi in particular has barely lost all year, which makes it the clearest ban target for any team drafting against T1.

Behind them sits a second tier of engage and dive junglers with winning records: Jarvan IV, Nocturne and Lee Sin. Wukong and Trundle round out the regular picks, again on winning records. Pantheon is the outlier. It is one of his busier champions this year, yet it has a losing record, and Naafiri, a pick he leaned on during the playoffs, has also lost more than it has won so far.

Skarner has a small but positive sample, and Poppy, Qiyana, Sejuani, Ambessa and Dr. Mundo have only appeared a handful of times between them. Those are pocket picks: they say more about how flexible T1’s drafts can be than about how strong the champion is in his hands. If you want to compare kits and current builds for any of these junglers, our champion pages cover each one.

Across his career, Xin Zhao, Lee Sin, Vi, Sejuani and Viego are his signature champions, with Nocturne holding one of the best career win rates in his pool and Viego last played in pro on 9 November 2025, the day T1 won Worlds 2025.

Oner builds his three most played junglers almost the same way. Black Cleaver and Sundered Sky form the fixed core on Vi, Xin Zhao and Jarvan IV, and Guardian Angel is the usual third item. Maw of Malmortius, Death’s Dance, Serpent’s Fang and Sterak’s Gage appear only as situational answers to specific threats.

That core tells you how he wants games to go. Black Cleaver and Sundered Sky are bruiser items that pay off in extended fights, not in a single burst combo, so the build assumes he will stay in skirmishes around the jungle and objectives. Guardian Angel as a third item is a statement too: he expects to be the first player into the enemy backline and wants a second life for doing it.

The runes follow the same plan. All three champions run Conqueror in Precision with Triumph and Cut Down, plus an Inspiration secondary for Magical Footwear and Cosmic Insight, always with Flash and Smite. The one change is Legend: Haste on Jarvan IV in place of Legend: Alacrity, which favors getting his engage back sooner over extra attack speed.

Oner’s latest games come from the LCK 2026 Season Playoffs, in September series against Hanwha Life Esports and Dplus Kia. The drafts show a jungler being moved around the pool rather than locked onto one comfort pick: Naafiri and Skarner came out more than once, alongside Nocturne, Vi, Lee Sin, Pantheon and Qiyana.

Every game in the table below has a VOD, so you can watch how his champion choice changed the early jungle plan from one game to the next.

Oner joined T1 on 13 January 2021 as the team’s jungler, and his career history lists no other organization. His first season ended at Worlds 2021, where T1 finished 3rd–4th, a strong result for a rookie jungler on a roster that was still being rebuilt.

2022 was the breakout year. T1 won LCK 2022 Spring and the LCK 2022 Spring Playoffs, then reached the final at both MSI 2022 and Worlds 2022 and finished 2nd at each. Those two near-misses set up everything that followed.

From 2023 the finals turned into titles. LCK 2023 Spring came first, then Worlds 2023, Worlds 2024 and the Esports World Cup 2024, then Worlds 2025 and the KeSPA Cup 2025. MSI is the one major international title missing: 3rd at MSI 2023 and MSI 2024, then 2nd at MSI 2025.

2026 has brought a 4th place at the Esports World Cup 2026, decided on 19 July 2026, a run through the LCK 2026 Season Playoffs, and another trip to Worlds.

Worlds 2023, Worlds 2024 and Worlds 2025 define Oner’s standing. Winning the World Championship in consecutive years as the same organization’s jungler is the core of his résumé, and it is why his champion pool and builds are studied by junglers far below pro level.

The rest of the list fills in the picture: domestic titles in 2022 and 2023, the Esports World Cup 2024, the KeSPA Cup 2025, and finals at MSI 2022, Worlds 2022 and MSI 2025. The table lists every placement.

Oner is at Worlds 2026 with T1, which qualified as Korea #3 and arrives as the reigning Worlds 2025 champion. T1 begins in the Main Event’s Swiss stage on 23 October 2026, with the Knockouts to follow for teams that advance. Follow every stage on the Worlds 2026 hub.

In ranked, Oner plays a different jungle pool from his pro one. On the Korean server, where he sits in Grandmaster, Lee Sin and Nidalee are his most played champions, followed by Graves, Vi and Viego. Nidalee, a signature pick early in his career, has not appeared in his pro games since 24 January 2025, so solo queue is the place to watch it.

His pro staples sit further down the ranked list, with Xin Zhao the highest-performing of them on a small sample, while picks such as Ekko, Kha’Zix, Ezreal and Naafiri give him room to experiment. He streams on SOOP and posts on YouTube; you can find him and other players in our streamers and pro players section.

Oner’s streamer page lists 675 solo queue games in our VOD library at a 55.3% win rate, currently Grandmaster (1,725 LP).
