Sonic and Tails encountered Silver Sonic during their mission to destroy Robotnik's new Death Egg space station, which despite its speed proved to be a formidable opponent. Silver Sonic's exoskeleton was invulnerable to Sonic's best hits. With a single powerful punch, it nearly knocked Sonic unconscious, but in the process it exposed electrical wires from inside the Death Egg. Before Silver Sonic could crush Sonic to death beneath its foot, Sonic used the cables to send thousands of volts of electricity into Silver Sonic, destroying its primary brain circuits and rendering him inoperable.
Robotnik, having witnessed the defeat of his creation, put on his Eggs-O-Skeleton armor so he could battle Sonic himself. However, Sonic was able to climb inside Silver Sonic's head and control the robot's body manually. Silver Sonic was so strong that Sonic was able to send Robotnik flying out of the Death Egg. Shortly afterwards, Tails activated the station's self-destruct sequence, and Sonic and Tails used Silver Sonic's body to escape safely back to Mobius.
- It was based on Mecha Sonic, the first boss of Sonic 2's Death Egg Zone. The name "Silver Sonic" was taken from the European manual
