Amon Sur

Amon Sur, son of celebrated Green Lantern, Abin Sur, is a family renegade who has turned to criminal acts due to feelings of neglect and anger, aimed at his father and the Green Lantern Corps.

Background
Feeling that his father, Abin Sur, had abandoned him in favour of the Green Lantern Corps, Amon Sur grew up to become the leader of the Black Circle; an intergalactic crime syndicate, as a form of rebellion against his father's memory.

While the syndicate is eventually put out of commission by Green Lantern (Kyle Rayner)], Amon continues his vendetta against the Green Lantern Corps and his father's memory, eventually receiving a [[Sinestro Corps power ring and becoming the Sinestro Corpsman of Sector 2814.
