Archie Sonic the Hedgehog Issue 110

"Station Square attacks!"
Sally gets a message from the President of Station Square late in the night that the O.T.I.S. (Outer Threat Immobilization System) has looked through the information about Dr Robotnik and has seen him as a threat to destroy. It has launched an atomic strike at Robotropolis that will poison the environment. Sonic and Tails race towards Robotropolis to call a truse with Dr Robotnik to save their home. Sonic wants him to shoot down the missiles, but Dr Robotnik has a force field to fire the missiles away from Robotropolis and onto the environment. Tails pretends to deactivate the force field so that Dr Robotnik has no choice but to shoot them down. Sonic and Tails make it out of Robotropolis just as the force field comes up when the missiles are inside. Robotropolis has been destroyed and Sonic tells Tails that Knothole is their home now.

"One for all"
Sally uses the Sword of Acorns to discover her destiny, but sees a vision of the Arachne attacking her and Sonic.
