Explosive Demon Wave (爆力魔波, Bakurikimaha; English "Exploding Powerful Demon Wave") is a very powerful blast shot from one hand, with the other arm supporting the one that is firing the attack. It was King Piccolo's most potent attack and he used it against Goku twice. The first time Tien intervened and carried Goku out of the blasts way, but the second time he hit the young warrior dead on, heavily injuring him. Similar—but unnamed (in the manga & anime at least)—techniques have been used by other characters over the course of the series; notably Goku, Frieza and Zarbon.
