Mr. Smith is an incredibly odd creature. No one really knows exactly what he is or where he came from. He spends most of his free time learning all he can about humans, keeping journals on them, taking pictures, maybe inappropriately stalking them around. He's even known to eat one or two on occasions...
In general, he comes off as nice if not a bit eccentric. He tries very hard to be nice to every human that he meets, as he has a genuine interest in learning more about them. Recently, he's taken a job a teacher as to get a better feel of the 'human experience'. He's actually doing a pretty good job! Though, it is kinda weird how some of his homeroom kids' parents have gone missing....
