Invisibility

Invisibility is the actually state, or ability, of an individual to be not visible.

Using the ability, the user can watch people without them noticing, being more specifically used on humans. Beings with this power can see each other. A good example being in Abandon All Hope.., when Castiel was able to spot all the reapers. 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.

Invisible can work differently depending on which species uses it, Fairies are invisible to all, unless they want to be seen, but anyone who has been to there realm can see them in our realm.

When invisible characters are also normally inaudible.
