He has a short goatee and a mustache.
Domon has a very loud voice and uses it to either announce or encourage the Qin troops.
It is assumed that he worked his way up the ranks to reach the position of General.
Domon is put in charge of the vanguard unit consisting of 8,000 troops and bolsters them all with his words before ordering the charge at the Wei troops. During the Sanyou Campaign, he is told that 1000-man commander Tai Un has been killed and notes that Taiun's unit was a hastily assembled one. Upon hearing another unit struggling, Domon deduces that someone on the enemy side is deliberately targeting the new units. He fights in the battle and holds the line, spurring his men on to follow him as he moves across the field.
On the fifth day of battle, Domon commands the men to hold firm in the center when he sees the Gaku Ka Unit advance forward. A messenger informs him that they are acting as an independent unit and have left 200 men to support the center army. On the sixth day, the Qin troops engage the Wei and the general moves to plug a gap on the right side believed to be Rin Ko attempting to break through. The position seems to recover slightly upon his arrival.
Do Mon is proficient with a glaive and can command men in battle.
