Shadow: Nephrite's Main ability, his shadow can detach itself from him and act independently. The Shadow can drain the energy of people for Nephrite and turn people into mannequins. It can also possess people or control people en mass. People controlled by Nephrite's Shadow can also brainwash others. Nephrite's Shadow can also create darkness, up to enough to cover a building-sized area. This darkness can swallow people up, causing them to disappear. The Shadow can also disguise itself and resisted the Banishment Charm of Sailor Mars.
As Nephrite's Shadow is literally just the shadow of Nephrite, it is likely that Nephrite himself can also use these same abilities if he wishes.
