The Mask of Electricity was created by the power flow after Tonga's defeat in Tonga's Attack. Henkka, as a Mega Matoran, wore the mask. It had the power to manipulate, create and control electricity. Henkka usually used the power to channel the electricity through his Ancient Staff. The mask was wiped from excistence and replaced by the Mask of Jokes accidently by Tapio in Tapio's Mistakes.
