Herobrine

A character that was never in the game. In 2010 an anonymous user posted a Minecraft screenshot of a player figure with no pupils standing in fog, and a story that it was the creator's brother. The rumour outlived every denial: for years players sent in evidence — squares of felled forest, sand pyramids, tunnels nobody built — and the developers eventually took to adding "Removed Herobrine" to their patch notes as a joke, though there was nothing to remove. His code has never existed in any version of the game.
