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.
Video Game Appearances
Kid Goku is able to use the attack in Dragon Ball Z: Ultimate Battle 22. In the Budokai Tenkaichi series, charged Ki Blasts which are fired like the Kamehameha and home to the opponent are used by Goku some of his various forms.
"Enter additional input after firing to make the Kamehameha chase your opponent!"
— Dragon Ball Xenoverse 2 Skill description
In Dragon Ball Xenoverse 2, it appears as a Super Skill used by Goku in his Turtle Hermit Gi 2 (which is his Weighted clothing removed outfit from the Raditz Saga which is likely a reference to its use during the battle with Raditz). Additional input allows the user to make the wave chase their opponent. Additionally the Future Warrior can obtain this technique by purchasing it at the Skill Shop. After the 1.09.00 Update, it can be added to Krillin's custom skillset after it has been purchased for 5 TP Medals in Partner Customization. It can also be added to Adult Gohan's custom skillset for 5 TP Medals as well.
