Invisibility is the ability to render oneself unseen by others. Bree was given an invisibility app, which was a hidden ability Douglas unlocked. Skylar has this ability, and has used it a lot in the past.

Users who are invisible can be detected with means that either sense heat or beings who are extremely perceptive or have enhanced senses. Users may not be able to tell (or even forget) if they're invisible, as Skylar said she can still see herself when invisible. It's not known if this is true of Bree when she turns invisible.
