Goku shouts "Ka... me... ha... me..." and backflips multiple times before facing the opponent. Then, he shouts "...ha!" And fires a Kamehameha from his feet, launching himself at the opponent and leaving him free to attack with his hands, serving as a great advantage.
Usage and Power
Goku used this attack during his match against Piccolo Jr. in the 23rd World Martial Arts Tournament. After exchanging blows with Piccolo Jr. up in the air, Goku got hit and started falling down to the ground head-first. However, just before he hit the ground, Goku fired the Feet Kamehameha at the ground, launching him back up in the air and double-punching the shocked Piccolo Jr. in the face.
However, it can also be used as a diving-style attack in the case of both Jump Super Stars and Jump Ultimate Stars (where it is used as Goku's midair strong attack in both normal and Super Saiyan forms).
