- "It's your tool, just as many other things in your world are your tools. A wheel instead of a leg; a mechno-lens instead of an eye. What does it matter? There is no shame in this. There is nothing inherently good or bad in it, unless you choose to use it as such. And it shall become a part of you. Every creature in this universe alters and evolves from minute to minute. We are not the same as we were only a day ago. We are ever changing, fated forever to exist in a state of decay and creation."

Cybernetics were technological replacements or enhancements for organic body parts, including eyes, limbs, and, in extreme cases, the majority of an individual's body, including whole new organ systems. A cyborg was an organic being who had large portions of their body replaced by cybernetics.
General Grievous, the cyborg leader of the Separatist Droid Army, had most of his body replaced by cybernetics. Anakin Skywalker had a cybernetic right forearm installed to replace the lost appendage after his duel with Count Dooku, and when he became Darth Vader, he was rebuilt with cybernetic parts by medical droids after having his limbs severed and nearly being burned to death. Luke Skywalker had a cybernetic right hand installed to replace the lost appendage after his duel with Darth Vader. The Junkers, a species from the planet Lotho Minor, regularly augmented their bodies with cybernetic enhancements. Fennec Shand had cybernetic enhancements implanted in her lower abdomen after she was shot by Toro Calican.
Denetrius Vidian once thought of getting cybernetic implants that would give him near-total memory recall, but decided against it, afraid of possibly harming any brain chemistry that gave him his perceived genius.
