Sometimes called "cyborgs" or "weapon enhancements", Cybernetic Enhancements allow one or more pieces of a person's anatomy to be substituted with a mechanical replacement. In nearly all cases, the replacement organ or appendage is superior in functionality to the original, but often at great cost to the recipient. Some cyborgs may have nearly all of their biological components replaced with cybernetic enhancements as in the case with Robot man. However, more often than not, cybernetic enhancement is restricted to specific limbs or organs. Cybernetic enhancement also applies to those whose bodies are enhanced by nanite technology or mechanical implants.
