Baek Doo San (Korean/Hangul: 백두산; Hanja: 白頭山) is a character in the Tekken series. Baek first appeared as a villain in Tekken 2, and he has returned for most titles with the exception of Tekken 3 and Tekken 4. In Tekken 2, Baek first appears as Marshall Law’s Stage Eight sub-boss.
Tekken 5 (鉄拳5 Tekken Faibu?, lit. Iron Fist 5) is the fifth main installment in the Tekken series of fighting games, first released on arcades in 2004 and ported to the PlayStation 2 home console in 2005. It was followed by an update, Tekken 5: Dark Resurrection. The gameplay of Tekken 5 is akin to the formula previously seen in Tekken 3, while it takes certain features that were introduced in Tekken 4. The game was released during the 10th anniversary of the series, and so the PlayStation 2 port came with an Arcade History mode where the arcade versions of the original trilogy are emulated and playable. The home version of Tekken 5 also came with new character customisation options and a mini-game called Devil Within.
