Battle of Central City
Dr. Eggman and his forces attacked Central City hoping to find the traitor, Snively Robotnik. Employing the Egg 'Stache Flyer, Egg Swats and Egg Camels, the doctor and his forces attacked the United Federation's capital in search of his treacherous lackey. G.U.N. retaliated with E-123 Omega leading a squad to fight against the Eggman Empire, while Shadow the Hedgehog and Rouge the Bat went to protect the President. Omega winded up fighting against Mecha Sally, Metal Sonic, and the Egg Paladins (the legionized soldiers of G.U.N.'s Paladin Team Sigma-Alpha 2). Eventually, Snively escaped, which caused Eggman to go after him. The empire made a retreat and left the city. (SU: #38)

The Chaotix chose to search the streets of Central City, where they where attacked and captured by Copy Robot, before being turned into Roboticized Masters. (SU: #51)
