In essence, energy waves are a type of technique where their user utilizes an assortment of ki-based waves, cast from (but not limited to) their palms, fingertips, eyes or mouth. The color of the aura they emit varies between users (for example, Kamehamehas launched by various users have ranged in color between blue, red and yellow). The most commonly seen energy waves in the series are the Kamehameha and Continuous Energy Bullets. 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.
