The Cyborg, a marvel of scientific and medical experimentation - is a human with such a elevated intelligence they have mechanically engineered their body to fit their ultimate needs. With the ability to alter the human body in so many ways that some do not even resemble the appearance of a human any longer.
A creature by most to be considered far more superior than just a human, with enhancements to alter anything from mental capacity to enhanced hearing. While the more drastic may enhance nearly every part of their body making the human they once were unrecognizable.
Some choosing to have these procedures done to enhance everyday life but others strictly wanting to give themselves a perceived advantage in a fight to overcome the other species that inhabit Miasma.
The cyborg a tricky foe since you can not always be sure what they have altered and will definitely have a few tricks up their sleeve. If you were to win a fight with a cyborg you should remember each time you meet them, a new enhancement could be in place.
