Tuha

Tuha Vuan is the leader of the Toa Vuan, a group of Dark Toa created by Teridax in order to serve his will.

Creation
When Tahu and the other Toa Nuva were captured by the Brotherhood of Makuta, a piece of their organic tissue was taken from each Toa. Eventually, each piece tissue developed into exact copies of the Toa Nuva in six large tubes in the Makuta's base. When the clones were fully developed, they broke out of their tubes. Teridax, in the form of his essence, spoke to them from his tube and made Prizik give them weapons and Kanohi similar to that of the Toa Nuva's, only the Kanohi had the exact opposite effects of the Toa Nuva's Kanohi. The Toa Vuan, along with Tuha, were dispatched by Durost in order to obtain the Kanohi Vahi from Vakama, who had it in the form of his badge of Office.

Theft of the Vahi
Tuha and the other Toa Vuan were part of the plan, along with Sakarix, that involved stealing the Kanohi Vahi from Vakama before he could give it to Vlakro (the Vahi was taken from Voporak by the Toa Hagah). Disguised as the Toa Nuva, they "helped" the Toa of Time defeat Sakarix (their attacks were merely illusions, though Vlakro's attacks were real).

Later, when they reached Spherus Magna's Ta-Koro, the Toa Vuan revealed themselves after Vlakro used his Rode to uncover Tuha's identity. Tuha and the rest of his team attacked and fought Vlakro, despite him being aided by the Glatorian Ackar. Tuha then steals Vakama's "Badge of Office", and escapes the village with his teammates.

Powers & Abilities
Tuha has control over Fire, which he can channel using his Magma Blades. He also has control over Shadow, which he can channel using his Magma Blades.

Tools and Masks
Tuha has a Dark Hau in the shape of a Hau Nuva. The Dark Hau, however, is the Kanohi Mask of Shattering, which allows the wearer to destroy almost any defense using the mask - the opposite of that Hau's effect. Tuha also carries two Magma Blades that channel his elemental Fire and Shadow powers. Like the real Tahu, he can make his blades form a Lavaboard.
