Herobrine/Video Games

Minecraft
Though Herobrine is not officially in the Minecraft game, countless mods have added him, retextured other mobs as him, or even allow the player to play as him by granting them his abilities. Herobrine has also been referenced by Mojang and Notch several times, including in tweets from Notch and other staff, in patch notes and messages, and even appearing in promotional material such as for Minecon 2011.
