Energy Wave is a type of technique where the user utilizes an assortment of ki-based waves, cast from (but not limited to) their palms, nose, fingertips, eyes, body, or mouth. It makes its debut with the commonly used energy wave called the Kamehameha. Goku refers to his energy wave as a "fireball". The color of the aura they emit varies between users (for example, a Kamehameha launched by various users have ranged in color between blue, red and yellow). Some of these waves can also home in on their targets, and with enough energy, their power, speed, force and size can be augmented. These attacks are capable of being improved as their users' concentration becomes more adept or they assume some type of transformation. The user sould be able to have full control of the beam or the beam can go anywhere as seen when Goten did it while fighting Trunks.
