Kirop

"All those years we spent hiding in the light ... we were wrong. We should have embraced the darkness from the start."

- Kirop

Kirop was a Shadow Matoran and formerly the leader of the Av-Matoran, making him the strongest of the Shadow Matoran because he knew all of the Av-Matoran's weaknesses. Kirop, along with the other Shadow Matoran, Av-Matoran, and Phantoka, resided in Karda Nui (Universe Core). After having his light sucked out by a Shadow Leech, Kirop became Chirox's partner, allowing Chirox to see through his eyes, something that became necessary due to Chirox's blindness.

The Toa Nuva captured Kirop and took his Keystone, and he then overheard a plan that they were talking about, and then escaped. However, this was the Toa's plan, and he led them straight to the Shadow Leech Hive.

Powers
Kirop could shoot shadow blasts out of his claw blades and also had a power called "sight stealing" when in physical contact with a Makuta. This power allowed him to temporaraly blind his foes.
