Explosive Demon Wave

The Explosive Demon Wave is fired from a single outstretched hand, with the other arm bracing the firing arm for stability. The user channels a massive amount of ki into the palm and releases it as a concentrated energy beam with enormous explosive potential. The technique was designed for pure destruction rather than precision, and its detonation radius can flatten everything in the surrounding area. King Piccolo favored it as a weapon of terror, and his son Piccolo inherited both the technique and the fearsome reputation that came with it.

King Piccolo used the Explosive Demon Wave to horrifying effect during his reign of terror in the original Dragon Ball series. After declaring himself ruler of Earth and abolishing all laws, he demonstrated his power by obliterating an entire section of a city with a single blast. The attack also played a central role in his battle against young Goku, where King Piccolo fired it point-blank to try to finish the boy off. Goku survived, barely, but the sheer power of the technique established King Piccolo as the most dangerous villain the series had seen up to that point.

As King Piccolo's reincarnation, Piccolo inherited the Explosive Demon Wave along with his father's other techniques and memories. Piccolo used variants of the attack throughout Dragon Ball Z, though he eventually developed his own signature techniques like the Special Beam Cannon and the Light Grenade. In Dragon Ball Super's manga, Seven-Three copied the Explosive Demon Wave after touching Piccolo, using the Namekian's own technique against him during the Galactic Patrol Prisoner Saga. The technique has appeared in numerous video games under both its original name and the localized title "Destructive Wave."
