Pridak

Pridak was a warlord and the leader of the Barraki warlords who led the League of Six Kingdoms. Pridak also planned to overthrow Mata Nui and conquer the Universe, but was defeated by Makuta Teridax, who obliterated the Barraki's armies and had Botar imprison Pridak and the other Barraki in The Pit. Years later, when Teridax cast Mata Nui into a deep coma, the Great Cataclysm occcured and damaged The Pit, which allowed Pridak and the other Barraki to escape into the ocean. Because of his attempt to usurp Mata Nui before Teridax did, Pridak is considered to be the Bigger bad in Bionicle.
