Invisibility is the ability to render oneself unseen.
Beings with this power can see each other, through Supernatural Perception. Castiel, an Angel, sees a group of reapers in Abandon All Hope... Invisibility can also be linked to be being on a different plane of reality. The Horsemen are naturally invisible, and can only be seen when chosen.
