Park Se-jun

Park is highly regarded as one of the best players in the world and has consistently made Top 8 finishes as a video game player at the Pokémon World Championships. He made his debut on the international stage in 2011 by finishing 2nd in the Senior Division of the 2011 Pokémon World Championships losing to Kamran Jahadi (2011, 1st place), and as a fresh Masters Division player in 2012, finished 5th at the 2012 Pokémon World Championships after losing to Wolfe Glick (2012, 2nd place) in the quarterfinals.

In 2013, Park repeated history and placed 5th again at the 2013 Pokémon World Championships in Vancouver, losing to Ryosuke Kosuge (2013, 2nd place) in the quarterfinals.

In the following year, Park won the 2014 South Korea Video Game National Championships. He then proceeded to win the 2014 Pokémon World Championships in Washington, D.C., defeating Jeudy Azzarelli in the Masters Division finals. Park was notable for being the first South Korean to win the Pokémon World Championships and to win with a Pachirisu in his team, which was much adored by fans. In honor of his achievements, Pokémon Korea hosted a celebratory event known as 'Champion's Day' in November 2014.

In 2016, Park earned an invitation to the 2016 Pokémon World Championships as a Trading Card Game player.

In December 2019, Park won the Pokémon World Champion Invitational 2020, a grassroots tournament for Pokémon Sword and Shield in which all video game World Champions from past years were invited to. He executed a flawless run during the tournament, defeating Ray Rizzo (2010, 2011, 2012), Paul Ruiz (2018) and Naoto Mizobuchi (2019) in pools, and then Wolfe Glick (2016) and Shoma Honami (2015) in the semifinals and finals respectively.

He played in the 2022 Pokémon World Championships with Team Eternity, a South Korean Pokémon Unite team. Team Eternity finished the tournament in eighth place.

In 2023, Park returned to TCG and qualified for the 2023 Pokémon World Championships, ending his run in the group stage.

A year later, he returned to his roots, qualifying for VGC at the 2024 Pokémon World Championships in Honolulu, his first Video Game Worlds in the Pokémon Scarlet and Violet era. His 2024 Worlds team also included Pachirisu, ten years after he won the World Championship with the Pokémon. However, he failed to advance to the second day, finishing with a 5-3 Swiss record.
