The popular story and screenshot detailing a Herobrine 'encounter', posted on 4chan's /x/ board on August 31, 2010. The original screenshot which inspired the 'White Eyes' story, from July 30, 2010, with an enhanced excerpt below. Any appearances of Herobrine are caused by either mods being installed or because of another player using the skin. It is not possible for Herobrine to have ever existed in any unmodded clients or servers. There are no references to him at all in the source code, and there is no code to allow for any entity to act like Herobrine. Herobrine is not in vanilla Minecraft, and never has been.
