The Kamehameha (かめはめ波は Kamehameha), aka "Turtle Devastation Wave", is the first energy attack shown in the Dragon Ball series. The Kamehameha is the most widely used finishing attack in the Dragon Ball series, and is Goku's signature technique. It is also a signature attack of the students of the Turtle School.

The Kamehameha is formed when cupped hands are drawn to the user's side and ki is concentrated into a single point (between their cupped hands). The hands are then thrust forward to shoot out a streaming, powerful beam of energy. The blast can also be used, generally under extenuating circumstances, with just one arm or even the feet. In most variants, the user utters the word "Ka-me-ha-me-HA!!!" as he/she charges and releases the attack.

The attack has been used by dozens of different characters, both heroic and villainous, and comes and just as many alternate versions with different colors, sizes, and shapes.

The attack is named after the Hawaiian King Kamehameha I, coupled with the Japanese word for "turtle" kame (亀), due to Master Roshi (the attack's inventor) also being known as the Turtle Hermit, and ha (波), meaning "wave".
