FNaF Robin (Robin Fazhuman) is an animatronic, main enemy off Mike Schmidt (you).
Robin rarely moves from the Titan Stage, when he moves, you can hear a sound, and it sounds like a thing dropped from his hand. Mostly his stick has dropped from his hand. Since he is a very dangerous animatronic, you could see his mask glowing in the Dining Area and hall corners.
When Robin kills you, he picks his stick and attacks your face, with the XSCREAM and blood goes out of your mask.
Like the other animatronics, Robin has lighter colors than the colors of the original characters, and Robin has a small top hat like Freddy Fazbear.
