Sergei Dragunov (Japanese: セルゲイ・ドラグノフ Serugei Doragunofu; Russian: Сергей Драгунов Sergey Dragunov) is a character in the Tekken series. He was first introduced in Tekken 5: Dark Resurrection as one of the two new characters, the other one being Lili, and has returned in every subsequent game. Dragunov is a member of the Spetsnaz (also known as the Russian Special Operatives) who have dubbed him "The White Angel of Death" because of his overwhelming fighting powers and inscrutable personality.

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. Sergei Dragunov entered the King of Iron Fist Tournament on army orders.

At the designated arena of his first match, a woman appeared before him. There was something strangely familiar about her... It didn't take Dragunov long to figure out who she was, and he wasted no time in readying himself for combat. Ending Description: After defeating Master Raven, Dragunov orders one of his soldier's military tankers to shoot her with a single missile. As his opponent burns in a blaze of fire, Dragunov walks away chuckling to himself and smirks at the camera.
