Amon Sur, son of the late Green Lantern Corps member Abin Sur, grew up to become the man in charge of the Black Circle crime syndicate. Amon was angry at his deceased father for abandoning him for the Corps and decided to take his anger out on all Green Lanterns. Amon was eventually stopped by Hal Jordan's successor, Kyle Rayner and a second-generation Guardian of the Universe named Lianna. Amon eventually had a confrontation with Hal Jordan himself, who returned to his Green Lantern role after being freed from the influence of Parallax. Hal defeated the insane youth, but Amon received a duplicate of Sinestro's ring from the Qwardians and vanished. After Hal finally took Abin's body home and buried it, a mysterious yellow light appeared in the sky after Hal left, presumably Amon arriving to visit his father's grave.
Amon Sur was recruited by the Sinestro Corps and chose to represent Space Sector 2814. During the Sinestro Corps War, the Book of Oa was rewritten, enabling Green Lantern Corps officers to use lethal force against their opponents. Fearing for his life, Amon Sur fled. After the war concluded, a group of the "Lost Lanterns" traveled to the planet Varva, where they found that Amon Sur had only recently slaughtered the civilian populace. Flying into a rage, Green Lantern Laira slew Amon Sur with her power ring.
