The Double Kamehameha is a variation of the Kamehameha technique used by Goku. When he uses it, he first points his hands at his left and right sides. Then he fires two Kamehameha blasts out of each hand pointed in opposite directions. It is quite useful for blasting enemies who are attacking at both sides, which Goku uses against Turles's henchmen in the movie The Tree of Might.There is another version of the Double Kamehameha that Goku uses against Frieza in the Frieza Saga. Instead of energy blasts, they are simply energy spheres that Goku controls. He launches them up one by one at Frieza as a distraction so that Goku could launch a sneak attack against the tyrant.
