Anti-Matter Machine

The Anti-Matter Machine is an object that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It was an experimental device created by Dr. Ivo Robotnik that could make objects intangible, invisible and inaudible for a short time.

History
Dr. Robotnik once hatched plan to lure Sonic the Hedgehog into a trap by spreading a rumor that he had build an Anti-Matter Machine that he could use to gain the upper-hand against his enemies. Sure enough, Sonic and Sally went to Robotropolis to investigate the rumor. After finding the machine, Sonic went into its chamber to blow it up with a homemade bomb. But Robotnik sprung his trap by sealing the room shut and then told Sonic that although the rumor was true, he failed to get the machine to work, so he decided to use it as bait instead. As Sonic was surrounded by SWATbots, he decided to detonate the bomb and escape the room before it exploded. But he tripped on a wire and failed to get out on time, making the other Knothole Freedom Fighters believe he was killed in the blast. However, Sonic survived and eventually found out the effects the machine had on him.
