DYNAMAC-3000, also known as DYNAMAC is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. They were large machines of great strength that could transform themselves and use metal cables in their chests to capture their foes. The DYNAMAC model is so powerful that the only way to defeat it is by shorting it out through a massive electric shock.
The DYNAMACs were made by Dr. Ivo Robotnik to gain control over the western portion of the continent using their weapons, but were stopped by the efforts of Sonic the Hedgehog, Sally Acorn and Geoffrey St. John with help from Rebel Underground agents Jean-Claude and Dolph while the first model was still being transported in the Robotnik Express.
The DYNAMAC was remotely piloted by Snively Robotnik whilst trying to retake Robotropolis after the Knothole Freedom Fighters had finally reclaimed the city and defeated his uncle, but Sonic and Bunnie Rabbot managed to defeat it.
