Xu Gong

Xu Gong (rōmaji: Kyo Kō) is the prefect of the Wu Territory who resisted Sun Ce alongside Wang Lang, Liu Biao, and many others. Although he was executed for secretly requesting aid from Cao Cao, his followers avenged him by ambushing Sun Ce with poisoned arrows before they were killed by Cheng Pu. Historically, Xu Gong was never truly an official under Sun Ce like in the novel.

Dynasty Warriors
In Dynasty Warriors 4: Xtreme Legends, Xu Gong is briefly mentioned during the narration of Da Qiao's Legend Mode stage. His loyal soldiers are the antagonists of that particular battle as they surround the young maiden to lure out Sun Ce. They manage to grievously wound him with various traps and ambushes. But as a result, all of their leading officers are killed by Da Qiao in turn.

Dynasty Warriors 7 has Xu Gong appear during a flashback scene in which he and Sun Ce argue. Portrayed as a nervous and paranoid individual, he is aghast at the idea of turning against Cao Cao and accidentally falls to his death below the castle walls. He ends up becoming one of the apparitions Yu Ji conjures to amplify Sun Ce's feelings of guilt.

In Shin Sangoku Musou 7, he conspires with Yu Ji and the Wei army to kill the isolated Sun Ce. Despite having his foe placed under a curse and cornered by troops within the fog-covered forest, Xu Gong is eventually subdued by the Little Conqueror's companions. Willing to die than submit in shame, he holds Sun Ce long enough for a spectral soldier to stab them both. Xu Gong dies as a result while Sun Ce suffers serious injuries that prevent him from repelling the assault of Cao Cao's men.

Romance of the Three Kingdoms
Xu Gong is a rather mediocre officer with average stats that lean more on war, politics, and intellect. He mainly suffers from an insufficient amount of leadership points.

Romance of the Three Kingdoms
In Chapter 29 of the novel, Xu Gong wrote a secret memo to Cao Cao stating, "Sun Ce is a turbulent hero much like Xiang Yu. The government ought, under the appearance of showing favor to him, to recall him to the capital for he is a danger in the southern provinces". The letter never reached its destination as the messenger carrying it was caught. After reading its contents, Sun Ce had the messenger beheaded and the sender strangled. Xu Gong's family was forced to flee Wujun afterwards.

Out for revenge, the loyalists of Xu Gong hatched a plot to kill Sun Ce by posing as members of Han Dang's troops and attacking him with spears and poison-tipped arrows. They continued assaulting him mercilessly until the arrival of Cheng Pu and his men led to them being hacked into pieces. Though Sun Ce had been greatly injured from the encounter, he would not pass away until encountering Yu Ji.
