Bioroid

A Bioroid is a synthetic being assembled either partly or entirely out of organic material. The line that separates it from a cyberized human comes down to one detail: it carries no cyberbrain, so it counts as a made lifeform rather than a person given machine parts.

Because a Bioroid leans on living tissue for some or all of its makeup, questions follow about how that material holds up. The stories never spell out whether its organic parts can be swapped and repaired the way mechanical ones are. Even so, one Bioroid survives injuries that should have killed it and turns up intact afterward, which suggests such damage does not always finish them off.

The clearest example is Proto, the technician who maintains Section 9's Tachikoma units and appears throughout Stand Alone Complex. The close of 2nd GIG reveals him to be an early Bioroid prototype, the source of his name, and despite grievous wounds at that story's climax he resurfaces in the Solid State Society film. Bioroids also sit at the center of Appleseed, a separate work by the same author, Masamune Shirow.
