Cybernetic

Cybernetic "creatures" are relatively ill-defined in the Unreal universe. In some instances, it refers to humans/other biological creatures who have been given robot parts, or even had their body entirely replaced by robotics, while in the next breath it means robots with artificial intelligence.

The line is never made clear and the terms "Cybernetic" and "Robot" are often used interchangeably, meaning that Xan Kriegor, Fate, and Corrosion are each described at some point as "Cybernetic", even though Xan is likely an AI (though there is a possibility he was once human), Fate is a human with many but not total cybernetic replacements, and Corrosion is 100% robotic AI. Therefore, common sense should be applied whenever the word "Cybernetic" is used to describe one's race in Unreal, unless Epic properly retcons the definitions.
