Updated Space Core cyborg design. Here is a view from behind that I was too lazy to ink.
Funfacts: the bars attached to his chest and lower abs are removable. His eyes, core and visor screen are all made from the same material. His voice can either be spoken naturally or broadcast from speakers, OR converted into radiowaves to be broadcast in that way. He eats and produces waste like normal humans but is more efficient and only needs to eat/discharge once every couple days. His hair is synthetic and doesn’t grow back when cut, but can easily be replaced.
(I could go on forever about this, but I don’t want to create a huge wall of text.)
