Lee "Chaser" Sang-hyun (Hangul: 이상현) is the jungler for 1907 Fenerbahce Esports.
Lee "Chaser" Sang-hyun was born on August 1, 1995 in Gyeonggi, South Korea. He began to play League of Legends in August 2012, and the first champion he played was Ashe.
Originally known as RealFoxy, Chaser subbed for the Jin Air Green Wings Stealths in PANDORA.TV Champions Winter 2013-2014 but the team failed to make it past the group stage. After the tournament, he was moved to the Jin Air Green Wings Falcons to become the starting jungler after ActScene left the team. The Falcons lost all of their games at HOT6iX Champions Spring 2014 and fell during the group stage. In May 2014 he was moved back to the Stealths and changed his ID to Chaser. The Stealths finally made it out of groups at HOT6iX Champions Summer 2014 but lost 3-0 in the quarterfinals to Samsung Blue.
Due to OGN rule changes, the Falcons and the Stealths were forced to merge to create the Jin Air Green Wings. He was meant to share the starting jungle spot with Winged but Chaser ended up playing in almost all of the games of SBENU Champions Spring 2015 anyways. Jin Air qualified for the playoffs but faltered at the end of the season, losing 3-0 to CJ Entus and ultimately placing 4th. Jin Air then attended SBENU Champions Summer 2015 but placed 6th overall, gaining 10 circuit points and qualifying for the next season of LCK but barely missing playoffs. Jin Air was seeded into the first round of the 2015 Season Korea Regional Finals and made it all the way to the finals but they lost 3-1 to KT Rolster.
Jin Air played in the 2015 LoL KeSPA Cup where they lost 2-0 in the quarterfinals to CJ Entus. Chaser did not play in this tournament. Chaser left Jin Air in November. He joined Incredible Miracle on December 5th. Incredible Miracle rebranded to Longzhu on January 3rd, 2016.
During the 2016 LCK Spring Season, Longzhu played with a 10-man roster, liberally using substitute players. Chaser shared play time with fellow jungler Crash. Longzhu finished the spring split in seventh place with an 8-10 set record, missing out on a spot in the playoffs. Longzhu fared poorly in the 2016 LCK Summer Season, going 7-11 in sets and netting them eighth place, letting them escape relegations.
