Antroz

"Is that enough to pique your interest, Icarax? We are going to lay waste to Karda Nui, seize the remaining Matoran, and kill the Toa Nuva. Make yourself useful - find that mysterious Toa and get that mask."

- Antroz

Antroz was a Makuta and the leader of the Phantoka Makuta that invaded Karda Nui. The Makuta under him were Vamprah, Chirox, Mutran and Icarax. He and the others were sent to the Universe Core to stop the awakening of the Great Spirit Mata Nui.

The Invasion of Karda Nui
Antroz was chosen to lead the Phantoka Makuta in Karda Nui and stop Mata Nui's awakening by turning Av-Matoran into Shadow Matoran. But when he got into the Universe Core he was blinded by the light of the Kanohi Ignika when Matoro put it on and revived Mata Nui. Thus he was forced to turn Radiak, an Av-Matoran, into a Shadow Matoran so he could see through his eyes and share his knowledge.

He and the other Makuta were attacking the Av-Matoran when the Toa Nuva appeared. After being shot by a beam of light from Pohatu's Midak Skyblaster, the Makuta decided to retreat momentarily to their lair, during which Antroz decided to ask for Icarax's help. During the final battle in the sky, Antroz's armor was scratched and his essence began to leak out. Mutran then ordered Antroz and the rest to retreat to the Swamp of Secrets following his Shadow blast.

Swamp of Secrets
In the Swamp of Secrets, Antroz hijacks a vehicle known as the Jetrax T6.

Abilities and Traits
Antroz was a skilled tactical commander and an accomplished warrior. Unlike Makuta Teridax, he did not underestimate his foes. He also had a rare sense of honor, opposing cheating and deceit and wishing to win a fight fairly. He, like Vamprah and Chirox, spread darkness wherever he flew.

Being a Makuta, Antroz possessed control over Shadow, the ability to create Kraata, shape-shifting abilities, as well as the forty-two Rahkshi powers.

Kanohi and Tools
He wore the Kanohi Jutlin, Great Mask of Corruption. It could cause objects to rot and break down. Antroz also used a Tridax Pod, which contained 4 Shadow Leeches. These Leeches were able to drain light out of beings. Along with that he used his new claws and poisonous teeth as  weapons.
