One of the animatronics the player is up against (he doesn't look like it in the picture, but just trust me on that). He is a very grumpy, but loyal and well-meaning person. In the scenario he's been written in, though, he's very hostile. He should probably sound like that too.

For a description of his voice, I guess I'm open to many interpretations, as this character has been written to be a very normal and boring person. A fairly-deep male teenager's voice should do it. Does that help? I'm not very confident in my explanations.

His speaking lines are very few and far between, actually; the only times he gets to talk are when he talks to the player upon killing them a-la Ultimate Custom Night, and during the ending sequence of the game.
