A device that allows instantaneous transportation between zones. It works by teleporting a subject from one zone to another and replacing it with a subject from the zone that the first subject was teleported to. The Mysterious Traveller planned to use such a device on Sonic, claiming that it was a gift that would make him "mega-cool". Tails used the device and was teleported to the Misery Zone, and a monster from there took his place in the Emerald Hill Zone. Tails made it back after Sonic threw the Inter-Zone Exchanger at the monster, transporting him back and returning Tails home.
