About this creation
The Toa of Chaos, wearing the Kanohi Mecha (mask of Chaos), and yielding the elemental power of poison, was once the leader of a small Toa group, who are all dead. They were killed in a final battle with Teridax, who met his fate at the hands of Skeletrok. Before, they were the ones who rescued Mata Nui, and brought the Glatorian to live on Metru Nui. Now, he has taken the form of a Dark-Toa, and was banished from Metru Nui by the Spirit of Mata Nui. Before he left Skirma Nui, he killed Takanuva, Kopaka, Nokama, Matau and Hewkii. Skeletrok has returned to Skirma Nui, and has built himself a dark forteress he named Magna (after the planet Bara Magna, which Teridax destroyed). He has enlisted the Dark Hunters and Bone Hunters as his new hecnhmen, and use the Vorox as palace guards. He is searching for the surviving members of the Brotherhood of Makuta to join his army.
