Mask of Elemental Energy

The Kanohi mask of Elemental Energy, was a great mask that instantly recharged a Toa's Elemental Energy. This mask was featured in the 2003 video game, Bionicle: The Game. Though the game was non-canon the mask has been confirmed to be part of the official canon.

In Bionicle: The Game
The Kanohi of Elemental Energy was a healing item when used, restoring all of a Toa Nuva's health and energy. Its powers were activated instantly upon grabbing the mask, and each one could only be used once.

The mask was scattered all over the levels, some right in plain sight, and others hidden well. In the trailer, it is seen dug up by Onua Nuva.

Trivia

 * Theoretically, this mask could be used by other beings who wield Elemental Energy, provided they could use Kanohi masks as well. Though only the Toa Mata/Toa Nuva have been seen using it.
 * This Kanohi mask is so old, that the true name has been lost to time.
 * The mask also appeared in BIONICLE Heroes, though this time it could not be used and was only to be viewed in the Trophy Room.
 * This Kanohi has an appearance similar to the Kanohi Iden that Toa Inika Matoro used to wear.


 * The kanohi of elemental energy might be released with a future bionicle set.
