Nocturn

Nocturn prefers to dwell alone, feeding on Razor Whales and giant Squid. He is skilled in every form of deep-sea combat, and is physically stronger than Makuta of Metru Nui himself, making him a force to be reckoned with. He was sent to The Pit after literally breaking his island in half in a fit of temper. Nocturn's species is amphibious and possess the ability to regrow lost limbs. Much of his anatomy is bioluminescent, causing him to give off a glow in low-light areas. He is one of the few beings in The Pit that is naturally immune to the mutagen in the water.

Nocturn is a lieutenant in Ehlek's army. He usually resides in the Razor Whale's Teeth, a rock formation that marks the center of Barraki-controlled territory.

Nocturn's last run-in with Pridak cost him one of his arms. The arm has since grown back, but its tentacle did not. Nocturn now carries his Squid Launcher in its place.

Nocturn's eventual possession of the Mask of Life will spark a war beneath the waves that threatens all of Mahri Nui. Despite his eventual possession of the Ignika, that does not mean that he is destined to carry it, he will be cursed when he handles the mask.
