Zilius Zox of the Red-Lantern of Sector 3544 is a member of the same species as the deceased Green Lanterns, Galius Zed and Cundiff Cood. Like his fellow Red Lanterns, he was called to the red light because he possessed the capacity for great anger. The Red Lantern was among the many red warriors who pledged allegiance to Atrocitus, swearing revenge against Sinestro and his depraved Sinestro Corps.
