Ukon

Ukon is sakon's twin brother. He sleeps in sakons body when he is not fighting. If he needs too he Leaves sakon's body and aids sakon in a fight whenever he needs him. He can also use a special asasination technique that allows him to leave sakon's body and enter an enemy's body, while he is in the enemy's body he slowly kills them by transfering cells and molecules. But if the enemy were to die (besides the technique slowly killing them) Ukon will also die. Not very much more is known about Ukon.
