First, Medamatcha charges a pink energy sphere in his hands. Then, he spins his arms around rapidly to fire a barrage of pink Ki Blasts.
In Dragon Ball Z: Lord Slug, Medamatcha uses this technique on Gohan, who fires a Ki Blast at him while Medamatcha is firing the attack, but Medamatcha deflects the blast and he keeps firing until Gohan is hit by the blasts. He later uses the Full Power Energy Blast Volley variation in combination with Angila, against Gohan and Piccolo.

It also appears as Medamatcha's Super Attack in Dokkan Battle though he only utilizes it when fought as a boss in the "Lord Slug" Story Event. During the story event, he uses the team attack variation with Angila against Gohan and Piccolo during a Story Event cutscene.
