Cat was a terran medic who served in Omega Squadron. Sometime after the Brood War, Cat was part of a Dominion Marine Corps force dispatched to Artika, doing battle against the zerg. As part of the first wave, Cat 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. A scanner sweep from a ComSat station eventually revealed them but despite the visual advantage, Cat was killed in battle against them.
