The members of this Legion chapter were once a horde of roboticized soldiers under Dr. Robotnik and set against Sand Blast City; however, they were among the Robians restored to their organic forms by the Bem. They tried to temporarily settle in Sand Blast City before setting out for their original homes, but they were met with suspicion and dislike from the Sand-Blasters who had defended the city from the mindless Robians in the past. The Sand-Blasters abused them and forced them out into the Badlands ("once a Robian, always a Robian" being the main argument). In desperation, they allied with the Eggman Empire in order to gain an edge against their oppressors, undergoing Legionization and building a settlement in the Badlands. Since then, the Great Desert Dark Egg Legion has manned the Oil Ocean Refinery, while waging a war against the inhabitants of Sand Blast City for an undetermined period of time.
Times got worse when, Beauregard's niece, Bunnie "Rabbot" D'Coolette, discovered them. "Uncle Beau" lovingly embraced her and told her about their dreadful history. She surprisingly agreed to help them take possesion of the Oil Ocean Refinery saying that "she never was good friends with the Sand-Blasters anyway." The next day, Bunnie, Beauregard, and some legionarres ventured to the Oil Ocean Refinery to claim what's their's, only for them to run into Sonic the Hedgehog and the Sand-Blasters. Getting off on the wrong foot, Sonic and Bunnie dueled against each other while the others watched with hope of success. Realizing that the Dark Egg Legion isn't all bad, but that it's still an arment of the Eggman Empire, Sonic and Bunnie began to destroy the Oil Ocean Refinery. The Dark Egg Legion and Sand-Blasters raced in and fought to stop Sonic and Bunnie and claim the refinery for themselves. Both failing in the attempt, started to argue with Sonic and Bunnie. Beauregard yelled at Sonic saying that Eggman will make him pay dearly for losing the refinery, but Bunnie told him that Eggman will concentrate on Sonic and ignore the fact that he lost it. With that being said, Beauregard and Bunnie said their goodbyes and parted ways.
