Xiao Fei Yeung was a Rear-Admiral, later the newly appointed Admiral of the United Earth Directorate. Before the Brood War, he was assigned to guard Earth from the Dominion, the Zerg, and the Protoss by his superior, Admiral Gerard Dugalle. When news reached when Dugalle and Vice Admiral Alexei Stukov were killed in action, Xiao succeeds Dugalle’s place and becomes the new Admiral of the UED. With his quirky prototype Adjutant named Shifty, he renamed his flagship “Dugalle’s Revenge” in honor of the late Admiral, prepares an armada to invade the Korpulu Sector once again. However, it is not the Dominion, the Protoss, or the Zerg who had encountered, but Amon and his minions somehow returned and his legacy continues to wreak havoc on the Sector. The Xiao-led UED forces will counter this new threat.
