Herobrine

"Herobrine" is the name of the mythical NPC player, who is supposed to have appeared in the single player mode of the game Minecraft (lives in a pineapple under the sea!).

The "Herobrine" character is said to be a clone of the current player, and appear very rarely. He can manipulate the map in the same way as the player, and is elusive, should you try to persue him.

It may have been speculated that Notch's brother added the code to the game. [citation needed]

Herobrine may have been a gaming name used by Notch's brother, or just a name given by the maker of the myth. [citation needed]

At present he is only a myth. Hoverver, the myth has drawn a lot of attention, and 'Notch' has said that Herobrine may be added to the game in the future.
