A Recognizer (also known as a Reco by both programs and Users; Ram also called them Demons) was a hovering vehicle used by the MCP’s army to capture conscripts and programs. It was extremely big and made an unique ominous sound when hovering. It captured programs by rotating its “legs” to make a single limb and literally “stomp” on the program, however this doesn’t harm the program but just simply captures it. What happens exactly right after a program gets “stomped” on by a recognizer is currently unknown.

CusCo was a company in Hill Valley located at 11249 Business Center Road. Ito T. Fujitsu was a supervisor at the plant, with Marty McFly and Douglas J. Needles working for him.

The center contained the oldest part of V’Ger – Voyager 6, an unmanned space probe launched by NASA in the late-1990s. The entire vessel surrounding the Voyager probe was built by an unknown race of machine entities in order to help it complete what the latter interpreted to be its primary programming: “learn all that is learnable,” and return that knowledge to its creator. During its journey, the probe came to think of itself as V’Ger after the only remaining legible letters from its original name, the “O”, “Y”, and “A” on the nameplate being obscured from encounters with previous spatial hazards, and amassed knowledge to such a degree as to become self-aware.
