Zof is a resident of Soleanna in Sonic the Hedgehog (2006). He is a dedicated employee of Rimlight, an organization which chiefly focuses on the energy obtained from Light Cores. He is aware of the importance of this energy to Soleanna and is always prepared to take action should it get stolen.
In Shadow's story, Zof is involved in his third Town Mission, though this task is provided by a G.U.N. soldier. A gang of thieves have stolen a vital fuel source from Rimlight and are attempting to escape via the highway in black cars. In response to this theft, Zof has contacted a member of the Guardian Units of Nations, who passes on the message to Shadow in Soleanna New City. The G.U.N. soldier orders him to track down and destroy the thieves' cars using an armed vehicle as a means of recovering the stolen energy.
