Dou Kin has a warrior's build, narrow eyes, goatee, and a mustache. He also has an earring on his left ear and the top of his head shaven off.
Dou Kin was deeply loyal to his lord as he instantly wept upon hearing the news of Ou Ki's death.
It is assumed that he has served in Ou Ki's battles in the past and has worked his way past being a 1000-man commander. As the commander of the 5th army, he is in charge of leading 8,000 troops into battle.
Dou Kin is first seen, prior to the battle, with Ou Ki and the other vassals as his lord surveys the terrain.
He is placed in charge of the 5th army of Qin. At the meeting Mou Bu has with Ou Ki, he is placed under Mou Bu's command along with the other commanders so they can attack the Zhao headquarters at once. On the fourth day of battle, his army charges at the Zhao headquarters some moments after Mou Bu's own, catching the Zhao by surprise. After the Zhao army retreats, he comments to all others present that they'll be impossible to see in the mountainous region and goes after the Zhao. His army and Rin Bou's are sent to checkmate the Zhao center army, leaving Ou Ki free to attack the Zhao headquarters.
During the start of the Coalition Army Invasion, Dou Kin arrives with Tou and Rin Bou to buy some time for the other generals to re-position their forces. Hacking his way through Chu troops, he encounters Rin Bu Kun and gives his name before his skull is broken by the Chu general's mace.
|Weakness: sudden attack|
|Notes: baldy beardy|
- As seen in a recent chapter, Dou Kin had a habit of mocking Roku O Mi's intense behavior during their encounter with Rin Shou Jin and his soldiers.
