Reflecting 95,000 years ago he along with the League Of Six Kingdoms were assigned to protect the Matorans alongside Teridax and his League Of Six Kingdoms. However Mantax and the League became very curious and greedy about the Chaos Emeralds believing it would make them the strongest beings in the universe. He along with Pridak and his League put their hands on the Chaos Emeralds without caution and resulted him into being mutated into an vicious Barraki. He along with the League began invading and conquering many planets but were easily defeated by Teridax and were about to be destroyed by the Makuta's use of Chaos Emeralds on them. Mata Nui and Ur-Didact stopped Teridax and imprisoned the League Of Six Kingdoms into the Cosmic Chamber. He along with the League trained the Nocturnus Clan into developing high technology and eventually escaped the Chamber after blasting the walls with their newly created Squid Launcher. After escaping the League discovers that they were imprisoned in the Cosmic Chamber for 4000 years with the Emeralds now hidden.
