Mask of Undeath

The Mask of Undeath is a Kanohi that siphons off a fraction of its user's life energy from his/her body, which it infuses his/her body with after death. The body is then animated by the life-force, although dead, and continues its previous objective from life. The mask gives the user no other special power and will slow down their thought processes, making it harder for them to fight. While undead, the user will lose all illumination in their eyes, making them empty and black.

bearers

 * An unnamed "fixed" Matoran of Karzahni

Trivia

 * Toa consider this to be an immoral Mask of Power, as the mask will essentially turn the wearer into a zombie after they die. Most other beings consider the Kanohi unlucky and deem it taboo.
 * The mask was originally part of a 2009 BZPower fan project, but Greg Farshtey approved it as official.
