Nocturn

Nocturn was a powerful being condemned for committing unpardonable crimes against the Matoran Universe.

Biography
Long ago, in a fit of rage, Nocturn destroyed his home island, and because of it, he was sentenced to the Pit.

Mahri Nui
After the Great Cataclysm freed him and the rest of the prisoners, Nocturn took residence in the Razor Whale's Teeth.

After the Mask of life was lost, Nocturn managed to avoid capture for three days. Then he was attacked by a raging Zyglak, a Maxilos Robot, and Toa Dumaire, who were trying to recapture him under Hydraxon's command. The trio was overwhelmed by Nocturn's strength, but Dumaire was able to hit one of his harpoons in his left eye. However, that just made him much more furious. The Zyglak and Dumaire ended up badly injured, and the Maxilos robot destroyed. When Nocturn had them cornered, he was raided by a Toa of Air named Lesovikk, Sarda and Sephxion. While the two Toa and the Zyglak kept him occupied, the two Matoran used the Maxilos' Cordak Blaster against the escaped warrior. It gave them the opportunity to finish him and defeat him.

Dumaire and the others had planned to take him alive, but the Zyglak impaled Nocturn with his dagger, killing him instantly. But, like all inhabitants of the Matoran Universe, he was revived on the Red Star.
