Bending Kamehameha (曲がるかめはめ波 Magaru Kamehameha, lit. "Bending Kamehame Wave") is a version of the Kamehameha for which the user can change the course, allowing the user to surprise his or her opponent.
Years later, Goku uses the Bending Kamehameha against Raditz, but Raditz easily blocks the attack.
While traveling to Namek around in the Capsule Corporation spaceship, Goku fires Bending Kamehameha waves in order to get Zenkai and increase his power. When fighting Captain Ginyu, Goku uses a Kamehameha, but the Saiyan has lost so much power that the attack bends away from Ginyu.
During the Cell Games, Cell uses a similar technique during the fight with Goku, when Goku attempts to get Cell to divert the Kamehameha upwards in order to keep the attack from destroying Earth as the android's power had been enough power to destroy Earth.
