DYNAMAC

DYNAMAC-3000s, also more simply known as DYNAMACs, were large machines of great strength that could transform themselves and use metal cables in their chests to capture their foes. They 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.

One 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. (SSS: #2)
