The Terminator, Series T-600 (sometimes T-600 Model or 600 Series) is a Terminator series mass-produced by Skynet starting in 2016. The T-600 Terminators serve as early Infiltrators featuring basic combat endoskeletons made of titanium alloy, which were sometimes covered in synthetic latex. As a result of their rubber skin covering, Resistance fighters could easily spot the T-600s in the field.
