This aquatic Lantern originates from Aeros, a water world inhabited by various forms of fish life. Able to breathe only through his gills, Naut Ke Loi must at all times wear a helmet filled with water. If this Green Lantern is ever without water for more than 5 minutes, he will perish. Though his build would suggest a smaller mass, Naut Ke Loi's cold-blooded fish-like structure makes him almost all muscle. His scaly skin is slimy to the touch and toxic to many species. This rapid swimmer is able to utilize his speed in space as well as in water.
