Ko Seok ‘HyuN’ was a Zerg progamer in Starcraft: Brood War, and was a member of team MBCGame HERO from 2005 to 2011.
His last result in the OnGameNet Starleague was an elimination in the first round of the 2011 Jin Air OSL, and he has an overall record of 84 wins and 110 losses in official Brood War matches.
HyuN began playing StarCraft II in November 2011, and was able to move up to Master League within the month. Though HyuN was known as an online player for quite some time, in late 2012, HyuN cemented himself as a legitimate tournament performer when he reached the Code S finals of the 2012 GSL Season 5 while simultaneously winning IGN Pro League Fight Club for 14 consecutive weeks.
HyuN made his transition to Heart of the Swarm a successful one in 2013 with a win at DreamHack Valencia, including a win over Jaedong in the finals, and a semifinal run at IEM Season VIII – New York that only ended after NaNiwa produced an inspired comeback after HyuN had taken a 2-0 lead.
