From the original creepy-pasta, Herobrine creates random constructions, such as pyramids and long 2-block-high tunnels. He also burns down, or cuts off leaves from trees, and creates cobblestone-complexes underground, much like dungeons, lit with redstone torches.
Herobrine first appeared in a single image detailing an encounter. It was posted on a thread in the forums, and gained very little attention. It stated how Herobrine had appeared in someone's single-player game, littering the map with various pyramids and tunnels. It is the first media to name him as Herobrine.
It was only later that Herobrine grew in popularity, when the Brocast staff staged a hoax in one of their live-streams. Herobrine was introduced to the stream here (at 20:45).
Later on, there was another video showing Herobrine in a user-made lava field. The livestream went down after the player ran and saved, only to resume ten minutes later, where Herobrine had disappeared.
During this stream, the player can be heard talking to his wife, stating he was trolling, which flooded the livestream chat with outrage. The player then faked a game crash.
During this crash, all watchers were redirected to another page, featuring Steve's face, but with real, frantically rolling eyes in the place of his block eyes, modified to be completely black.
When viewing the page's source, there were a jumble of characters and letters. after removing all non-alphabet characters, the following message was revealed.
It has been reported that some victims of torture, during the act, would retreat into a fantasy world from which they could not WAKE UP. In this catatonic state, the victim lived in a world just like their normal one, except they weren't being tortured. The only way that they realized they needed to WAKE UP was a note they found in their fantasy world. It would tell them about their condition, and tell them to WAKE UP. Even then, it would often take months until they were ready to discard their fantasy world and PLEASE WAKE UP.
"The message keeps telling the viewer to "wake up", implying they're living in a fantasy world, and this text hidden in the page is their "note".
It is widely believed all of his appearances in the stream are retextured paintings or iron doors. frames taken from the stream indicate he was very flat to the wall, making paintings the likely cause. This indicates they were using a specialised HD texture pack, but with low-res textures for all other blocks.
Since then, there has been a huge increase in his popularity, propelling Herobrine to meme status, and making him an icon of the community. There are several mods, animations, pieces of artwork"
