KJ

Matheus "KJ" Santos Jungles Diniz (born October 23, 1999) is a Brazilian professional Dota 2 support player currently playing for LGD Gaming. Also known as KingJungles, KJ is one of the most important players South America has produced in the last decade—not because of flashy stats or highlight plays, but because he is the captain and drafter who has quietly taken every team he's been a part of to places they had no business reaching.

Early Career

KJ started competing in 2018 with NoPing e-sports, grinding through Brazilian regional circuits alongside players nobody had heard of at the time. The early years were low-profile—ESL Brazil Premier League, VKS, SG e-sports, and BR—the typical SA development path with no shortcuts. He hit 8,000 MMR in July 2020, which was solid but not spectacular. What was building quietly underneath was something harder to measure: his ability to read drafts, manage personalities, and keep a team structured under pressure. By the time he joined Heroic in January 2024, he had been playing professional Dota for six years without ever getting a platform that matched his actual level.

The Heroic Chapter

Heroic was built around KJ from day one. The founding roster—K1, 4nalog, Scofield, Davai Lama, and KJ—came together in January 2024, and from the beginning they were the captain handling drafts and calling the shots. The team won PGL Wallachia Season 2 in October 2024, the first major international LAN title for a South American team. KJ was the one drafting it. They qualified for The International twice, finishing 5th-6th at TI 2025—the best TI result LATAM has ever produced. He was there for all of it, behind the scenes, making the calls that put the team in position to win.

The 2025 chapter had its turbulence. Parker left under circumstances KJ addressed publicly in March 2026, going on stream to explain what had happened—straightforward, no drama, just honesty. The roster rebuilt around Yuma, TaiLung, and Wisper adapted with KJ still at the wheel. Heroic, as an org, dissolved in May 2026, citing the game as financially unsustainable. Days later, the players were wearing LGD jerseys.

LGD Gaming

When KJ spoke about the LGD signing on stream, he said he couldn't even explain the feeling. That he'd always wanted to know what it felt like to wear that jersey. That the weight of representing a club that big was extra motivation. For a player who spent years grinding Brazilian regionals before anyone knew his name, that reaction tells you everything about where he came from and what this moment means. LGD went all the way to the BLAST Slam VII grand final in Copenhagen under his leadership — losing to Team Yandex 3-1, but finishing 2nd in the most watched LGD game since the old Chinese era. Not bad for a squad that didn't have an org name three weeks before the tournament started.

Playstyle and Reputation

KJ plays position 5 — the hard-support role — but his real value has always been above the game, not in it. He is the captain and drafter. He studies opponents, identifies weaknesses across a series, and adapts mid-tournament in ways that most SA teams historically have not. Coach Kaffs has been alongside him the entire time, which helps, but the tactical identity of every roster KJ has been part of has been his. The heroic drafts that beat European teams on their own turf, the TI playoff run, and the BLAST Slam VII grand final push—that is KJ's work.

Fun Facts

KJ hit 10,000 MMR in August 2023, 13,000 in October 2024, 14,000 in February 2025, and 15,000 in March 2025. That's three MMR milestones in five months at the peak of his competitive career.

In a TI 2025 interview, KJ said he and Yuma were eating tacos together and talking about how they were going to win TI. That's the whole vibe of this team in one image.
