Mask of Adaptation

The Mask of Adaptation was a Kanohi which automatically altered its user's body to adapt to their surroundings, including combat situations, local environs, and the weather. The mask was always on at a low level, scanning the environment; if it sensed the user needed to adapt, the mask would change them immediately.

The mask's alteration of the user lasted indefinitely, until/unless they were forced, or chose, to change back to their original form. After an adaptation, the mask's power would return to passively scanning for the wearer.

If the Kanohi was knocked off while the user was in an altered state, then they were stuck in that form until it was retrieved.

Trivia

 * The mask was originally part of a 2009 BZPower fan project, but BIONICLE writer Greg Farshtey approved it as official.
 * This mask power was inspired by the Kraata and Rahkshi of the same power.
