Herobrine

Herobrine is a urban legend from the game, Minecraft. He is popular with the Minecraft community in the fact of his creepy and rather disturbing presence, causing havoc on the player in some cases (especially in dreams, usually saying "WAKE UP").

Legend
The most well-known and most common rendition of the rumor is that a gamer while in single player mode found an NPC with the default skin - but with "empty eyes." Following the encounter, strange occurances start happening in his game, such as man-made objects appearing that he did not create, such as trees missing their leaves, perfect 2x2 tunnels underground lit with redstone torches, and pyramids of sand in the ocean.

He states he posted the topic on the forum where it is removed. A user by the name of Herobrine sends him a message telling him to "stop". The player is contacted by an administrator, claiming him alongside other players have encountered a pseudo player. Upon further research, Herobrine is discovered to be Notch's brother. The player personally emails Notch asking if he had a brother. After some time, Notch responded with this short message:

"I did, but he is no longer with us."

Impact
Notch has tweeted that he does not have a brother (besides a half-brother he hardly knows). However, the Mojang members have constantly teased the community by adding "Removed Herobrine" every time they make an update, fueling the fire more so. Herobrine also has his own Mod, where he usually torments the player with blood-curling screams and making them seem delusional by ordering chickens and other usually friendly mobs to attack the player. Herobrine is also added as plug-ins for some multi-player severs, making some believe he's actually real.
