Kamehameha

Kamehameha is Goku, Kaiō-ken Goku, and Super Saiyan Goku's standard special move in Super Smash Flash 2. Goku, Kaiō-ken Goku, or Super Sayian Goku, concentrates his Ki into a single point between his hands and then thrusts forward to shoot out a powerful beam of ki energy called the Kamehameha Wave (亀破波, かめはめは, lit. "Turtle Devastation Wave"). This attack has infinite range, but decreases in power as it gains distance. In addition, if Super Saiyan Goku uses the move when it is fully charged, he will turn into his SSJ3 form. When used by Kaiō-ken Goku, it is called the 20x Kaiō-ken Kamehameha. If Goku doesn't fully charge Kaio-ken Kamehameha, it will be "3x Kaio-ken kamehameha". If it is in the middle of chargeing, then it is called 4x Kaio-ken Kamehameha. 20x Kaio-ken kamehameha is actulally called the kamehameha wave as called on in the dragonball wiki
