Reverse Kamehameha (逆かめはめ波) is jet-fired version of the Kamehameha. The user fires a Kamehameha directly at the ground, propelling them up through the air in a jet-like manner. The technique is mainly used as a way to change directions quickly, remain airborne longer, or to fly through the air quickly, all of which apply for non-fliers. Master Roshi first used this technique as Jackie Chun during his match against Krillin at the 21st World Martial Arts Tournament.
Goku also used the Reverse Kamehameha during his match against Tien in the 22nd World Martial Arts Tournament and later in the final battle against King Piccolo.
Goten also used it in the form of a hand-stand during his match against Trunks in the 25th World Martial Arts Tournament while using the "Assault!" rush.
Reverse Kamehameha was named in Dragon Ball Z: Super Gokuden: Totsugeki-Hen.
