Svyatoslav "HappyZerg" Vlasyuk, also known as "SlaViK", is a Zerg player from Ukraine, who is currently retired.


HappyZerg was a competitive Brood War player. He was notoriously disqualified from Pokerstrategy TSL for ladder abuse.[1]

He reached A- on iccup ladder [2]

He was top5-6 at Ukraine's National WCG finals.

Wings of Liberty[edit]

HappyZerg joined Natus Vincere when they created their StarCraft II division.[3] He mainly participated in weekly online tournaments, but in July 2011, Natus Vincere announced they had sent him in Korea in order to compete in GSL Code B.[4] His first attempt to qualify for Code A wasn't successful, as he was eliminated early in the Code B bracket by PartinG.[5]

On December 30, HappyZerg became teamless after Natus Vincere disbanded.[6] He was picked-up by Guild of Imbalance on January 5, 2012.[7] He joined FXO alongside other former Guild of Imbalance members when FXOpen parted ways with the Guild.

ESV TV Korean Weekly[edit]

On September 6, 2011, HappyZerg participated in the ESV TV Korean Weekly Season 1 Weekly 8. After taking down Cutter and Line, HappyZerg went on to face TaeJa. He was not able to advance any further after he lost to TaeJa by a score of 0-3 and fell in to the 3rd/4th place match. HappyZerg once again wasn't able to grab any more victories and had to settle for fourth place after losing to ByuN by a score of 0-2.

In 2012 he qualified for the Battle at Ministry of Win and for IPL5, but couldn't go because team refused to send him there.

Heart of the Swarm[edit]

On April 9, 2013, Natus Vincere announced a merger with FXO.Europe, resulting in all European players with the exception of the inactive Elbegast to play under Na'Vi.[8] Despite being fairly successful, Na'Vi disbanded their SC2 team on 1 November 2013,[9] but HappyZerg retained a sponsorship from ESFXtv.[10]
