In the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics, this robot, referred to as Silver Sonic v2.0 or Silver Sonic II, was a Badnik in the Metal Sonic Series created by Dr. Eggman. When Eggman failed to destroy Station Square with Chaos, he sent Silver Sonic II to attack the city as revenge. However, it was defeated by the Knothole Freedom Fighters and Nate Morgan reprogrammed it to serve as the city's defender. It was later destroyed in the line of duty by Shadow the Hedgehog.
- This robot bares a very strong resemblance to the Mecha Sonic featured in Sonic the Hedgehog 2 (16-bit). Notably, both are taller than Sonic and have wheels on their heels.
- Several design elements of the robot such as the torso, knees, fingers and eyes resemble Mechagodzilla's design from his original film debut.
