A cyborg is a fusion of biological and machine parts. There are two classes of cyborg:
Partial Cyborgs are living creatures whose bodies contain mechanical or electronic parts. They do not qualify for the Machine meta-trait. Someone with an artificial heart, bionic leg, or a neural interface implant is a partial cyborg. These cybernetic modifications are covered in the Cybernetics section.
Total Cyborgs are robot bodies that house an living brain and (sometimes) parts of the spinal cord. Aside from this, they are machines. A total cyborg has a computer that controls many of its functions, but the guiding intelligence is the biological brain. In the case of a total cyborg, the robot’s computer is reduced one size (e.g., a personal computer becomes a small computer) and a cyborg brain case inserted.
No special lens is required for a total cyborg: use the unmodified racial template, except that the computer is one size smaller than indicated. Some robot bodies aren’t big enough to contain a human-sized brain case; see the individual descriptions. The cyborg brain rules in Cybernetics specify the space required.
