Herobrine is a legend that's nearly as old as Minecraft itself, first being referenced in the game's alpha before stories of the character proliferated in the early 2010s. The question with Herobrine, especially if you were on the younger side in those days, was always whether he was real and could be found in the game: or whether it was just a meme that refused to die.
There's an enormous amount to unpack about Herobrine's story over the years, but the short version is that he's supposed to be a ghost that haunts the worlds of singleplayer games, and the subject of endless creepypasta accounts of how he's interfered with players' worlds. Herobrine looks like Steve, who I guess we could call the main character of Minecraft, except for one detail: blank white eyes.
