In his first form Cooler uses the Death Flash, charging the attack with both of his hands upward and firing with his hands forward. When Goku falls into the river after being blasted by Cooler, Cooler hunts him and fires his Death Flash at him.
Cooler also uses the Death Flash in his final form, but this time charging the attack with his one hand backward, as oppose to the first Death Flash he used in his First Form. He uses it against Super Saiyan Goku, as a diversion to charge his Supernova, with the Death Flash having no effect on Goku.
