Mighty Powerful God Shockwave (豪力神撃波 Kouriki Shingeki-Ha) is a technique used by South Supreme Kai.
South Supreme Kai charges up a green Full Power Energy Ball in his hand, then rushes towards the opponent and fires it a point-blank range, inflicting massive damage. If the attack misses the target, the sphere will become a Homing Energy Blast.
