Nidhiki (DMU)

Nidhiki was a Toa of Air whose actions created the splinter timeline known as the Dark Mirror Universe. He was also a high-ranking member of the Toa Empire.

Creation of the Dark Mirror Universe
Nidhiki was originally a member of a large Toa team that was led by Lhikan and was responsible for the protection of Metru Nui. When Lhikan discovered that one of their own, Tuyet, was using an extraordinary powerful device named the Nui Stone to kill Matoran and frame the Dark Hunters for their deaths, he asked Nidhiki to come with him to confront her. Nidhiki agreed, but primarily because he was curious about the Nui Stone. When he bore witness to the awesome power that the Stone contained, he was presented with a choice: either side with Lhikan and destroy the Nui Stone, preventing anyone from abusing its power ever again, or side with Tuyet and reap the rewards that the Stone could give him. Nidhiki decided to side with Tuyet and killed Lhikan, which created the splinter timeline known as the Dark Mirror Universe. Together, he and Tuyet established the Toa Empire.

Toa Empire
Nidhiki remained a high-ranking member of the Empire for the next 3500 years. One day, he was put in charge of a squad that was tasked with wiping out the Nynrah Ghosts to prevent them from potentially creating something that could be used against Tuyet. Nidhiki and his squad killed four dozen Matoran on this mission. When Pohatu discovered this, he was so sickened by Nidhiki and Tuyet's crimes that he allied himself with the resistance to bring them to justice.

Dusk and Dawn
Following the death of Tuyet, Nidhiki attended a meeting of world leaders organized by Dume to discuss what the future of their universe would become now that the Toa Empire had fallen. In the meeting, Nidhiki, Onua, and Karzahni represented what remained of the Empire.

Elemental Powers

 * Air Creation - Nidhiki could create varying amounts of air through both his Toa Tool and his hands.
 * Air Control - Nidhiki had complete control over air, and could change air currents to create anything from a gentle breeze to a small tornado.
 * Air Absorption - Nidhiki could absorb certain amounts of air into his body, which became stored for use in future elemental attacks.
 * Air Nova Blast - In extreme circumstances, Nidhiki could release all of his elemental energy in the form of an air Nova Blast, which would be a wind strong enough to devastate an area the size of a large city.

Mask Powers

 * Stealth - When Nidhiki's Kanohi Volitak was activated, he became mostly transparent and all of his movements were silenced. However, he still cast a shadow while in this state.
