Minecraft wiki entry for Herobrine, associated text: In the Vengeful variation, he tries to ensnare the player in traps, presumably to steal their items. He waits for people to enter his dungeons, then either seals them inside, or teleports behind them, presumably killing them. Some rarer variations of this particular version says he breaks the player's creations, and steals their items from chests. This variation is likely inspired by griefers and trolls.
