Parr is a resident of Soleanna in Sonic the Hedgehog (2006). He is a soldier from the Guardian Units of Nations. He is something of a messenger to the agency, receiving distress calls from people, passing on information about emergencies to other agents, and reporting back to headquarters after completing an assignment.
In Shadow's story, Parr gives Shadow his thirteenth Town Mission. Badniks have invaded Soleanna Castle Town and have stolen some valuable information from the Rimlight Corporation, a company involved with the energy from Light Cores. The information is stored on three disks, and Shadow's task is to destroy the robots and reclaim these disks.
