The Sky Spy is an object that appears in the Sonic the Hedgehog television series. It was a space station used by Dr. Robotnik to spy and gather information across all of Mobius, primarily to locate the Knothole Freedom Fighters' home base.
The Sky Spy is a giant green-grey satellite with several satellite antennae coming out of it from various angles.
After Dr. Robotnik launched the Sky Spy, the Freedom Fighters became aware of its existence. As such, Rotor and Sonic the Hedgehog used a rocker booster to infiltrate the Sky Spy. Although they ran into trouble among the robots that operated the Sky Spy, the duo was able to sabotage it enough to cause it to break apart. As the Sky Spy fell down to Mobius, the Freedom Fighters used a giant magnet to guide it away from Knothole and make it crash into the wastelands.
