Cyborg-Well, just about everybody that isn’t a stick-in-the-mud pony. Not obvious modifications for the most part, but augmentations are standard in a lot of ways. Between the brain-interface system, nano-machines that keep you from being diseased and speed up your healing, and general improvements that make you much more capable than a baseline pony. A lot of these basic augmentations are the start for more extensive modifications that soldiers and explorers get.
And many of these augmentations are available to the public.
