Gronson "Shifty" Takkaro was a Dug gambler and former manager of the Daystar Casino on Ahakista. At some point, he worked as a bookmaker for Jenkes, who managed a gladiator arena on the planet Nyriaan. Later, Takkaro became indebted to Hack Fenlon, an Imperial senator, and a bounty was placed on him. Subsequently, Takkaro fled to the planet Lothal and was pursued by bounty hunter Bossk. Bossk's efforts to apprehend Takkaro were stymied by Jenkes, who had become an Imperial Security Bureau official and was seeking to return a favor to Takkaro. With the help of a Lothalian youth named Ezra Bridger, Bossk succeeded in exposing Jenkes' corruption.
