Ariszek is a large and powerful ex-Makuta that had a huge role in the running of the Brotherhood's base on Destral, and was once close to becoming leader of the Brotherhood of Makuta, but declined the offer after becoming aware of Teridax's plan to overthrow Miserix afraid that he would be disposed of in a smiliar manner. Once Teridax become leader of the BoM, Ariszek left the organization under Teridax's consent, after decieving the powerful Makuta into believing that his power was waning, and that he had to "tie up loose ends" before his time came to pass away. In truth, he left the BoM because he knew that, at some point, Teridax would eliminate all other Makuta to ensure his place as ruler of the Matoran Universe.
