Kraahkan

The Kanohi Kraahkan was the Great Mask of Shadows. It was made and kept in Artahka, until it was stolen by the Makuta.

When Makuta Teridax and Toa Takanuva merged to form Takutanuva, the Kraahkan and Avohkii also merged, forming a mask with the powers of both Light and Shadow, or unofficially known as the Mask of Light and Darkness. However, the two beings and their masks soon split apart again.

When the Piraka entered Mangaia, Reidak attempted to claim the Kraakhan from the shattered armor of Teridax, but it pummeled him with energy until he threw it into the Silver Sea.

Sometime after this, Makuta Icarax dived into the sea and emerged with the Kanohi Kraahkan. He then replaced his old mask with it, but he later lost it after he was killed by the storm made by the Toa Ignika.

Powers
