The Kanohi Kraahkan was the only Great Mask of Shadows in the Matoran Universe.
A mask of incredible power, the Kanohi Kraahkan was crafted from ProtoSteel in Artakha. It was then worn by the Makuta Tarel until it was taken from his corpse by Makuta Teridax. During the Conflict of Takanuva and Teridax, when Teridax and Takanuva merged to form Takutanuva, their masks also merged into the Kraavohkii. However, Takutanuva and his mask soon split apart. When the Piraka went to the Great Barrier to raid Teridax's lair, Reidak tried to steal the mask. However, it blasted him with Shadow bolts when he picked it up, so he threw it into the Silver Sea. The Mask of Shadows was later retrieved by Makuta Icarax, who began to wear it.
In the Toa Empire Alternate Universe, the Kanohi Kraahkan was taken from Teridax by the Toa Empire and put in the Archives as a trophy. It was also warded, so that if anyone touched it, the Toa Empire would know.
The Kanohi Kraahkan gave its' user Makuta-level range and strength of power over the Elemental Powers of Anger, Fear, and Shadow. It also let the user see moral darkness in others. The Mask of Shadows automatically sent out Shadow bolts to attack non-Makuta beings who touched it whenever it was not being worn. Even though the mask granted the user Shadow powers, it did not boost any pre-existing Elemental Shadow powers.
In Legacy of Evil, when Reidak picked up the Kanohi Kraahkan, it automatically blasted him with Shadow bolts until he released it.
