Features and abilities
When activated, device emits a light that slows the flow of time down. While it is unknown how slow time becomes, one second in real time appears to last a few minutes. Speedsters like Sonic are partially immune to the Slow Motion Machine however, as their super speed abilities are only reduced to normal levels. Dr. Eggman has as well an unspecified method of circumventing it.
The Slow Motion Machine was conceived by Dr. Eggman when he needed more time on New Year's Eve to keep his resolution of beating Sonic just once that year. Harnessing the energy core of a slow cooker, Eggman deployed the Slow Motion in the Village Center. With Eggman and Sonic circumventing the Slow Motion Machine's effects (the latter due to his super speed), Sonic's only option to restore time was to accept Eggman's challenges. When Sonic let Eggman win, the doctor shut down the Slow Motion Machine to gloat, but no one believed him.
