GHOST IN THE MACHINE

Herobrine is a legend in Minecraft, the star of a creepypasta not dissimilar to Slender Man. The character appears in singleplayer games, so the story went, where he does weird things like carving 2 x 2 tunnels in the rocks or cutting all the leaves off of trees; he looks identical to the default Minecraft skin, but with white, empty eyes.

First reported in a itself in the early 2010s.
