Avery

When Sonic the Hedgehog and Miles "Tails" Prower first arrived in Sand Blast City, the hedgehog found himself the object of hero worship. However, it turned out that the leader of the Sand Blasters, Jack Rabbit, planned to force Sonic to stay in the city as its protector against the Robian hoard beyond the city's force field dome. Not wanting to be kept against their will, Sonic and Tails were forced to make a break for it. Avery was among the group attempting to recapture (but not harm) the two. Despite this, Sonic destroyed the force field generator, and he and Tails escaped. The Sand Blasters were left to fend off the Robians themselves.

By 3237, the Robians of the region had all been returned to normal; however, they later joined the Dark Egg Legion, becoming a local chapter at odds with the Sand Blasters. As a precaution against the cybernetic-enhanced army, Avery constructed a number of EMP beacons around the city designed to disable the Legionnaires, providing an extra layer of protection in addition to the force field dome. Avery was in the process of moving heavy equipment within the city when Sonic the hedgehog suddenly burst from the ground, accusing the Sand Blasters of having attacked Bunnie "Rabbot" D'Coolette. Regarding Sonic as a traitor, Avery hurled his box of equipment at the hedgehog, who dodged the blow. The Sand Blasters were largely outclassed by Sonic, but he was eventually stopped by Tex and confronted by Jack. Eventually, it was determined that Bunnie had run afoul of one of Avery's EMP beacons and had been captured by the Dark Egg Legion; Jack offered to help Sonic rescue her if the hedgehog, in turn, helped the Sand Blasters take over the Oil Ocean Refinery guarded by the Legion. Sonic agreed, and the next morning, the group set out for the refinery, Avery driving the vehicle carrying Sonic and Jack.
