Cyborgs

A cyborg is a human or other life form who has been modified with machinery and metal for better functioning. These mechanical enhancements can include cybernetic replacements for missing organs or body parts, metal skin for extra protection, and weapons installed somewhere in the body.

Cyborgs in One Piece
In One Piece, cyborgs are somewhat rare, as the technology required for their creation is somewhat advanced. Those who are cyborgs have an advantage in battle, as they are more powerful than regular humans in both offense and defense.
