Dexter's Accomplices is term designed to categorize everyone who have discovered Dexter's secret as a serial killer. For the purposes of this wiki, these accomplices are divided into three categories: Masters, Apprentices and Partners. Masters are accomplices who have bent Dexter to their will at one point and had them kill from them. Apprentices are killers who Dexter trained personally in his killing art. Partners (Short for Partners-in-Crime) are accomplices who are aware of Dexter's killer nature and help him cover up his activities and even kill people to this effect.
