Ehlek was the most anxious of the Barraki, partially because he had to use an elaborate breathing helmet when operating on land and that made him vulnerable. For this reason, he made more fortresses than any of the other Barraki for protection. It is unknown what territories Ehlek controlled in the League of Six Kingdoms. He also believed the League was betrayed to the Brotherhood of Makuta all those centuries ago, and Pridak was the prime suspect as a former Brotherhood lieutenant. In his original army, Ehlek had noticeably more members of his own race than the other Barraki had of their respective races.
He was recaptured by Hydraxon and put back into the pit. However, he was released, along with the other Barraki, to join the war to defeat the Brotherhood of Makuta. Before he and the other Barraki could march on Metru Nui, Teridax was killed and Ehlek left the Matoran Universe. His Mutations were later undone by Mata Nui.
