Beyond the Stars
Cybernetics are essentially technological enhancements made to the body. They are not like prosthetic, which simply recreate a particular part to be used the same way, but are instead parts added to change or enhance how parts of the body work.
Humans have been progressing rapidly with cybernetics but have yet to reach the technological superiority of the Stoma or the Plasmans. Cybernetics are still incredibly expensive and difficult to put in the body without damage which has limited their use among all species. Not all candidates are even fit for cybernetics and many bodies refuse the implants outright.
