Choi ‘Bomber’ Ji Sung is a Korean Terran player that is currently playing under a private sponsorship from Red Bull.
Bomber was one of the first four South Koreans to be invited to MLG Columbus as part of a new partnership between MLG and GSL. However, due to Visa related issues, he could not go and so he was replaced by MC. He later participated in DreamHack Summer 2011, where he made it out of the group stage and into the playoffs, where he was defeated by Moon but ended up beating July to secure third place. Since Bomber could not participate at MLG Columbus due to Visa issues, he was invited to MLG Raleigh as one of the South Korean participants from the GSL-MLG Exchange Program. There, Bomber managed to place first in his group going 5-0 and then defeated DongRaeGu and CoCa to reach the Grand Finals. After defeating CoCa once again 4-1 in an extended series, he emerged as the champion. Bomber was one of twelve participants at the first StarCraft II Red Bull LAN on September 30 to October 2, 2011.
Like previous champions, MLG invited Bomber to MLG Orlando to try and defend his title. There, he placed first in his group, losing only to SaSe. He then went on to lose 2-1 to TheStC in the Winner’s Semi-Finals and was eliminated 2-1 by IdrA in his next match, a long, incredibly close match, earning him 6th place.
Bomber decided to change regions in 2014 and successfully qualified for 2014 WCS America Season 1 Challenger by placing top 5 in the Ladder Wildcard Qualifier.
