A highly decorated Corpsman, Okonoko spent years training his apprentice, Sir Deeter, to be an even better Green Lantern than himself. Okonoko retired when Deeter earned his Lantern status, but was happily recruited back into the Green Lantern Corps when they returned. It was a life he had missed. He was horrified to learn of the Sinestro Corps' creation, and has volunteered to track the yellow power rings searching for new recruits throughout his sector.
