Humanoid Hunter Killer Units are androids developed and intended to be similar to a human endoskeleton in look and function.

Later, Skynet studied the human body and the knowledge to create the Infiltrators, machines that look and behave more like real humans with real skin, so they could infiltrate the Resistance.

Terminator Series

A number of Terminator series have been released over the years. Some series have sub-series which are basically a improved version of the original series. Sometimes the fuel system were upgraded or the CPU were replaced with a more advanced chip. Further divergent timelines show evidence of additional advanced, increasingly organic infiltrating Terminator series developed and fielded in both the past and Skynet dominated futures.
