Dragunov is cold, calculating, and totally impassive when fighting opponents. Aside from a few lines of dialogue, Dragunov is an elective mute, barely uttering a single word throughout the entire series. This tends to either annoy, confuse or unsettle other characters. He serves his motherland with utmost diligence and loyally follows orders when given. He also enjoys singing as a hobby as seen in one of his win animations where he was humming after defeating his opponent.
Despite not being necessarily evil, Dragunov is very stoic and unreadable. He shows little interest in socializing with others and only focuses on the mission at hand. He shows no mercy towards his enemies or opponents and if provoked enough, will kill them if they are jeopardizing the mission. Because of these qualities, even his allies tend to be intimidated by his presence.
This is Sergei Dragunov's complete Tekken story line.
