Varix was a venerable law enforcement officer on the planet Naktos. He was given his ring by the aging Green-Lantern Ghrelk after Ghrelk was forced to retire due to a mysterious illness that destroyed his brain. Varix was a hypochondriac. In addition to his predecessor's fall to disease, half of his world was decimated by the yellow plague of Ghera. He was a member of the Green Lantern Corps serving in the Alpha-Lanterns and he protected Sector 0069.
