Zevonn Parzzx was a rookie member of the Green Lantern Corps from the frigid planet Citcratana in Space Sector 3590. A sadistic offshoot of the villainous Sinestro Corps began hunting down the GLC's family members, and one of them slaughtered Zevonn's mother, Zonna Parzzx. Her eyes were removed and sent to Oa as a message for those who dared cross the Sinestro Corps' path.
