- "I can shoot a balloon!"
- — Mokujin's suggestion on how to wake Alisa up.
Mokujin is a training dummy made from a 2,000-year-old oak tree. In Tekken 3, AncientOgre brought him to life. In Tekken 5 and its update, Jinpachi Mishima brought him to life. Azazel was implied to have brought Mokujin to life in Tekken 6 and its update. In Tekken: Blood Vengeance, he was the star of the Mokujin Exhibition. A lot of Mokujins were summoned by Heihachi Mishima to create a gigantic monster, otherwise known as the Mokujin Monster. In Alisa's Adventures in Rockoland, a single Mokujin appears and Evil-Man is the one that brought him to life with his Rocko Power-Upper.
The Mokujin Monster from Tekken: Blood Vengeance is voiced by Charlotte Bell, who also voiced Nina Williams. The Mokujin from Alisa's Adventures in Rockoland is voiced by Paul Dobson, who also voices Doctor Doom and Shuma-Gorath in Marvel vs. Capcom 3: Fate of Two Worlds, although he has Doctor Doom's voice during the series.
