Billy.

Billy, known online as Billy Sees All or BillySeesAll, is a stick figure that has a mind of it's own. It is treated as godlike in some all cultures and uses the internet to communicate with people.

Appearance
Billy is reported to be a generic black and white stick figure. It has a white face with black outlines. The outlines serve as the torso, the arms, and the legs. Billy has two black dots for eyes and his mouth stretches almost all the way across his face from one side to the other.

Personality
Billy prefers not to speak in reality, but his personality can be shown as a bit destructive. When communicating with players on an online game, Billy is shown to destroy things (in building games) and create new, unique structures on top of them. In chatrooms, Billy is silent. To indicate this, he will post "(cold silence)" when he joins a room.

There are Billy impersonators, but since Billy has an account on everything, he is known as BillySeesAll or BillyIsWatching.
