Herobrine was an NPC claimed to haunt minecraft. Removed from the latest patch! WHAT!?! So he was real?
This is crazy. I thought I saw this guy one time, then when I followed the direction he was in, I found some 2x2 pathways dug out, small pyramids and a massive, further then I could see 5x5 downwards hole. Freaky shit.
He is a retexture of the default skin without eyes. There are some pretty awesome mods out there that actually create this guy and make him play. Crazy.
Here's original the story.
