A non-humaniform robot designed and built on the Spacer planet Aurora by Dr. Han Fastolfe, Giskard seems to the protagonist, Elijah Baley, a fairly primitive robot. His covering is metallic but somehow woven, shifting in color as he moves. Initially he addresses Baley as "sir" rather than "master," as is proper on Earth. He is, indeed, created on Aurora and comes to Earth with R. Daneel Olivaw to guard Baley as he comes to Aurora to investigate a murder. Daneel, a humaniform robot, rates Giskard as rugged and fully cognizant of the importance of his mission to protect Baley, even if it means being destroyed in the process.
