Silver Sonic II, also known as Silver Sonic v2.0, was one of many robotic duplicates 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. After being defeated by Sonic, Silver Sonic II was reprogrammed by Nate Morgan to act as the city's defender against Eggman. Some time later he was destroyed in a confrontation with Shadow the Hedgehog.
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 held in cryotubes on board the Egg Carrier. However, before he would use them, Eggman unleashed 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.

Attacking Station Square and Reprogrammed
Silver Sonic II was finally released from its cryotube and unleashed against a vulnerable Station Square. It caught the Knothole Freedom Fighters off guard during a farewell celebration, and began its attack. Despite being attacked by the combined might of Big the Cat, Tails, Amy, Sally and Bunnie Rabbot, Silver Sonic II easily handled them; however, when Sonic entered the fight, it found itself at odds with the speedy hedgehog.

After its Sonic-tracking missiles failed to hit their target, Silver Sonic II brought Sonic underneath an apartment complex. It took down the structure's main support beam, causing the building to collapse 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. (StH: #85)
Just before Silver Sonic II could blast Sonic with its lasers, Sonic let go, causing Silver Sonic II to blow apart its leg and send its 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 decapitated his robo-duplicate with a Spin Dash, causing it's body to crash and go limp. (StH: #85)
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 it. When Eggman returned to the city, Silver Sonic II quickly chased him out of it, following him until Eggman fell into a hole which led to his maternal grandfather's underground base. (StH: #85, #98)
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, it arrived on the scene too late, and Shadow simply used his Chaos Control to destroy Silver Sonic II once and for all. Its remains were picked up by detective J.J. Moto and examined, and he has not been seen since. (StH: #98)
For a robot, Silver Sonic II carried a surprisingly large personality, mirroring the actual Sonic the Hedgehog's, and even using some of his regular quotes, such as "way past". Despite this, however, it had no compunction about harming others, though its primary objective was to kill Sonic the Hedgehog. After it was reprogrammed by Nate Morgan, it fought as a protector against evil and stood up for justice. (StH: #85)
Silver Sonic II, like many robotic Sonic models, possessed super speed, strength, and flight capability. It was much smaller and lighter than the previous Silver Sonic, with less armor so as to afford it greater speed. It was also heavily armed, with lasers, missiles, and grappling hooks to deploy against enemies.
- Silver Sonic II can be seen inside one of the cryotubes inside Eggman's Mystic Ruins Base Adventure Field level in the game Sonic Adventure. Though featuring slightly different colors in the game, Silver Sonic II was based off this model, and it can be assumed they are the same robot.
- The first Silver Sonic was invented by the original Robotnik, during the Sonic Quest Miniseries. This version was based on the second-last boss of the game Sonic the Hedgehog 2, though its comic version was not as visually similar to his game counterpart as Silver Sonic II was to its.
