Angila opens his mouth wide and charges a yellow energy sphere. Then, he fires it as an energy wave from his mouth, causing a considerable amount of damage.
Angila uses this technique when fighting against Goku. After the latter killed Medamatcha, Angila grabs Goku with his Mystic Attack and fires this attack. But the desperate attack backfires when Goku deflects it back into Angila's mouth, destroying his head.
