Reidak was a Skakdi who lived on a small island off the coast of Zakaz until the Skakdi's long lasting war reached the island and destroyed it. A group of Dark Hunter mercenaries found Reidak and recruited him. Later, Reidak and five other Skakdi defected from the Dark Hunters and became the notorious Piraka criminals. Years later, Makuta Teridax was supposedly killed by Takanuva, toa of light, and Reidak and the others looted his lair when Zaktan, leader of the Piraka, was possessed by a living Teridax to steal the Ignika, the mask of life, from Voya Nui. Later, Reidak attempted to steal the Ignika.
