The Night Guard is a pretty clever character! Whenever he feels scared or in danger, he puts on a Freddy mask to blend in, and the animatronics think he's one of them. It’s a funny trick that works on almost all of them—except for Foxy.  Foxy seems to have a unique ability to see right through the disguise. It makes for some entertaining moments, and having great comedic timing is really important for this role!
