Phone Guy

Phone Guy is a supporting character in Five Nights at Freddy's, Five Nights at Freddy's 2, and Five Nights at Freddy's 3. He returns as an antagonist in the Ultimate Custom Night.

Appearance
It is unknown what Phone Guy might look like because you never see him, you only hear his voice and only see the phone you get the call on.

Ultimate Custom Night
He will call at random into your office, and you will only have a brief amount of time to mute his call. If you fail to mute the call then you will be forced to listen to the whole thing, which will aggravate you as well as any animatronic that is sensitive to the noise level. Also, the mute button will appear in unpredictable locations.

=Gameplay= He will call you sometimes, and you must mute his call before he begins. But the problem is that the "Mute Call" button is always on a different part of the screen every time he calls, which may make it difficult to find; and if you don't click on the mute button in time then he will disturb every noise sensitive animatronic in the building, leading potentially to a jumpscare.

Trivia
If the player fails to mute Phone Guy in time, they will be forced to listen to one of the calls from the first three games. It eventually ends without finishing, however. ◾ On April 1st, Scott Cawthon supposedly added Phone Guy's mechanic along with Foxy and Nightmare Freddy. However, the mechanic turned out to be an April Fool's joke, referencing the common theory of Phone Guy originally being Springtrap's identity. The mechanic reads:

'''“ He will call into your office at random, creating a lot of noise and momentarily increasing the aggressiveness of the animatronics. He cannot call, however, if Springtrap is in the vents, because he can’t be in two places at the same time. ” '''
