This is Orriki in his Toaform. It is said that back in the day, Orriki was the third Toa ever created in the universe. He met and fell in love with Toa Helryx. He joined the Brotherhood to make a living. Miserix was impressed by Orriki, for Orriki was a star in the eyes of Mata Nui, and Miserix. When Teridax wanted to take over, Orriki didn't want to be killed, so he sided with him. He didn't like it one bit, so he confronyted Teridax and the two of them fought in a battle to the death. Teridax won and injected Antidermis into his mind. Orriki was then turned into a Makuta. Krataka had freed him from his Makuta self and Orriki joined Hydros' team. Orriki payed Krataka back by turning Krataka back into a Toa of Light.
Orriki is a Toa of Sonics, and he wields a double bladed scythe with a Midak Skyblaster. His Mask is the Kanohi Iden, the Great Mask of Spirit, Which allows the user to release it Spirit from their body.
Quote:"Teridax, In the name of Mata Nui, You are under Arrest." -Orriki to Teridax
