The Mask of Ultimate Power

The Mask of Ultimate Power is the most powerful mask of them all, though nobody knows what abilities it has. It has proven to be the most difficult and dangerous to study as it shorts out most equipment and causes level wide power outages. If it touches someone's skin, that person will die.

Trivia

 * If this mask is based off of Bionicle, then we do actually know what power it holds-The power to control all six elements of Bionicle. (Fire, Water, Air, Earth, Stone, Ice).
