First, Piccolo holds both of his arms at his side and charges electricity around his body. Then, he pulls his right arm back and swings it forward to fire a funnel of energy-charged air at the opponent, inflicting a great deal of damage.
Piccolo uses this attack against Nappa when the Saiyan charges in to attack Krillin. However, Nappa stops and side steps out of the way of the Destructive Wind, causing it to instead collide with and destroy a nearby mountain.
