Silver Sonic v2.0

Silver Sonic II was one of many robotic duplicate of Sonic the Hedgehog created by Dr. Eggman. A modified and scaled down version of the original Silver Sonic, Silver Sonic II was sent out to destroy Station Square after Dr. Eggman's plan to take over the city using the chaos entity known as Chaos failed.

Creation
Prior to his summoning of the water creature Chaos, Dr. Eggman began working on at least two robotic duplicates of his most hated enemy; Sonic the Hedgehog. The two completed models were help in cryotubes on board the Egg Carrier. However, before he would use them, Eggman unleased his other newly created robots, the E-100 series. After Chaos was defeated by Super Sonic and returned to the Black Emerald, Eggman was adamant on getting revenge, specifically against Sonic. He decided Silver Sonic II was the robot for the job.

Attack on Station Square
Silver Sonic II was finally released from his cryotube and unleashed against a vulnerable Station Square. He caught the Freedom Fighters off guard during a farewell celebration, and began his attack. Despite being attacked by the combined might of Big the Cat, Tails, Amy, Sally and Bunnie Rabbot, Silver Sonic easily handled them. However, when Sonic entered the fight, he found himself at odds with the speedy hedgehog.

After his Sonic-tracking missiles failed to hit their target, Silver Sonic II brought Sonic underneath an apartment complex. He took down the structure's main support beam, causing the building collapsed in the hopes of it crushing Sonic. Silver Sonic II emerged unscathed, with no sign of Sonic. Believing Sonic to have died, the robotic replica took off. While flying over the city, Sonic broke out from under the ground and grabbed onto the machine's legs.

Just before Silver Sonic II could blast Sonic with his lasers, Sonic let go, causing SSII to block apart his leg and send his foot flying. Tails managed to grab Sonic in mid air to prevent him from falling to his death, but Silver Sonic II's steel foot happened to hit Tails in the head, knocking him out. Angered at the sight of his young friend injured, Sonic spun-dashed his robo-duplicate's head off, causing his body to crash and go limp. (StH: #85)

City's Defender
Realizing that Station Square would still be vulnerable to attack as soon as they left, and that Dr. Eggman would likely return to the city to repair Silver Sonic II, Nate Morgan reprogrammed the bot to serve as the city's protector against the mad scientist, in addition to repairing him. When Eggman returned to the city, he found himself chased out by the city's new protector. (StH: #85)

Some time later, Shadow the Hedgehog came to Station Square, having been recently released by Dr. Eggman. His objective was to break into the city's bank and steal their only Chaos Emerald so that he could perform Chaos Control. Silver Sonic II realized Shadow was a threat and attempted to prevent the theft from occurring. However, he arrived on the scene too late, and Shadow simply used his Chaos Control to destroy Silver Sonic II once and for all. His remains were picked up by detective J.J. Moto and examined, and he has not been seen since. (StH: #98)
