Kaioken is a technique created by King Kai in the Other World. It can be used by all races and is accessible at level 25. This technique is obtained by going to King Kai's planet and finding Bubbles, King Kai's monkey friend. This transformation grants the user a 125 percent stat boost (the race specific forms give 150 percent stat boost and are obtained at level 100), this can be " stacked " onto any race's level 100 transformation giving the user a 175 percent stat boost.
