Mokujin is a 2000 year old training dummy made from an oak tree. It becomes alive every time it senses evil presence in the world.

It first came to life when Ogre appeared, but after his defeat Mokujin became lifeless again for two years. But when it sensed the evil, that was in Jinpachi Mishima it once again came to life and went to rid the world of it. After the defeat of Jinpachi Mokujin didn't go back to be a motionless training dummy because Azazel's evil kept him alive. Mokujin once again made his way to battle evil in the world.

Mokujin is a master of all styles and can mimic any of them during a fight.
