Thomas "JazBas" Cho is a New Zealander StarCraft II player, currently playing for Downfall Gaming.


JazBas is a New Zealand player living in Auckland and is of Korean heritage. Growing up with games like Brood War he quickly became one of the more notable players from New Zealand, and one of many New Zealand players of Korean heritage who formed the social SEA clan nGen. He is known for showing great improvement over a short time, playing himself up from Bronze league with well-rounded play and his own style.

In his personal life, he majors in jazz and plays the bass guitar (both upright and electric), leading to his ID JazBas, which is a contraction of Jazz Bass. Another piece of trivia is JazBas' part in SEA's own version of the “Artosis Pylon” - During a clan match between nGen and Terror Australis, JazBas flew 30+ mutalisks into a bunch of marines in a game against Rossi. This lead to the phrase "JazBas’ing mutalisks" or "magic boxing marines" whenever mutalisks fly into marines.

Wings Of Liberty[edit]

Despite a Brood War background, JazBas started off in Bronze league but was one of the founding players in nGen. While in this clan his skill increased dramatically and he became a feature in many SEA online tournaments and offline events in New Zealand.

JazBas was one of the players from SEA to qualify for the BlizzCon 2011 tournament. He lost to Sen in the first round, 1-2, and then managed to beat MajOr in his first match of the lower bracket. JazBas would then be taken out in the following match by TooDming, 0-2.

In August 2011, Jazbas was announced as one of the founding members of Xeria Gaming, a Professional Gaming Team based in Australia/ New Zealand

On November 16, 2011, JazBas joined Team inFinity, a social team/clan, after his previous clan "New Generations" disbanded.[1]

On August 16, 2012, JazBas left Xeria Gaming and joined GAMECOM Nv.
