Stun your enemies with awesome lightning powers!   Summoned from deep beneath Okoto's oceans, the Storm Beast can create thunderstorms at will. Kopaka the Uniter of Ice has lost his Unity Mask to the villainous creature, who can now control the elements against his enemies. Cause lightning to strike more than once!
