Walter Hartford

Walter "Doc" Hartford is a swashbuckling character who fights with a sword, a gun, and his fists. He is a computer genius who, along with the BETA Scientist 'Q-Ball', is responsible for most of the automated systems that the Galaxy Rangers use daily. His series 5 implants allow him to communicate with, and control, special programs called 'tweakers' which appear as flying holographic computer animated geometric shapes. Ranger Hartford's implant produces the oddest effects- and they still cannot properly be explained. Commander Walsh puts it best: Doc Hartford, your implant makes you a computer wizard, able to conjure fantastic programs.

Doc carries a Computer Diagnostic Unit; a compact computer which has advanced diagnostics and maintenance functions, along with sensory and computer linkage capability. The CDU acts as a focus for Doc's implant power, and also as a storage facility for his "tweakers" (Pathfinder, Tripwire, Firefly, Searchlight, Lifeline and Pixel). His "tweaker" computer programs are part of his personality and offer capabilities far beyond any normal computer program, virus, or worm. His implant gives him control over his "tweakers" via simple verbal communication, and his "tweakers" give Doc control over any computer system.

Hartford, from the Island of Jamaica, was born to wealthy parents, and so he was educated in private school, topped off with Mrs. Abercrombies Charm and Finishing School. He left there to join the Ranger Corps after he signed up with some biochemical corporations to help them produce better computer programs, but found out that his skills were not being challenged.
