How do you throw a psi-ball like they do on DragonBallZ?
The Kamehameha is formed when cupped hands are drawn to the user's side and the ki is concentrated into a single point between the cupped hands. The hands are then thrust forward to shoot out a streaming, powerful beam of ki energy. The blast can also be used with just one arm. In most variants, the user utters the word "Kamehameha" as he/she charges and releases the attack.
