Biography: Nirvax is the hunter of the Makuta, prefering to chase his prey in silence. When his unknowing prey makes a wrong move, he strikes. His eyesight is horrible, but all his other senses are greatly enhanced. Also, he doesn’t have any feet, so he rarely moves over ground. Because of his stealth, Teridax sent him to Karda Nui to spy on the Toa Nuva. Nirvax --and Krika-- discovered that Teridax would kill all the other Makuta, so there would be no competition. Nirvax found Vamgoraz and Slicerax and told them about what he (and Krika) had discovered. He, along with Slicerax and Vamgoraz, managed to escape from the swamp before they were killed by the Energy Storms.
When they were discussing their plans, Rahak appeared and killed him and Slicerax.
Mask and tools: Nirvax wears the Mask of Hunger, which he uses to drain light and energy from his opponents. He can do this from a big distance, as long as he can feel their presence. He has poisonous spikes on his arms, and knives instead of feet. He has large, sturdy wings on his back that he can use as shields. He wields the Dagger of Fear, which is very sharp and can cause someone to be immobilized by fear. He has sharp pincers on his left hand, which he uses to tear through armor (and sometimes for climbing). He has two Air Shields, which he uses to control the element of Air.
Powers and abilities: Because of the Mutagen in the swamp, he lost access to most Rahkshi Powers. He still has the power of invisibility, density control, and the ability to create illusions. He can also create Kraata, but he never uses that power.
