Yo-hown was a terran marine who served in Omega Squadron. Sometime after the Brood War, Yo-hown was part of a Dominion Marine Corps force dispatched to Artika, doing battle against the zerg. As part of the first wave, Yo-hown and the rest of Charlie Squad secured the landing zone, defeating the zerg sent against them and moving on to the secondary objective. However, they were set upon by a group of Dark Templar and although a scanner sweep from a ComSat station revealed them, Yo-hown was killed in the process.
