Androids

Semi-organic humanoid machines, Androids are used for all the same reasons as Tankborn, bar use as soldiers. Androids are far to expensive to be used in such a manner.

From the outside, Androids look human (Or any other species that they may be modeled after, though that's a rarity itself), and even with a little bit of cutting that illusion is maintained. Somewhat similar organs, though artificial, with the only real and immediate difference being the differing color of their internal fluids. This color isn't universal, though it's often a rather vibrant sapphire color.

Androids often rack the complete human emotional range, which aids them in the execution of their often-role as servants (their emotional range tends to be muted, resulting in a lack of stronger and responsive emotion, rather than missing one big one like anger).
