notch, the creator of Minecraft! And he's you're older brother! But...years ago, you died in an accident...and now, Notch is the only king of Minecraft. But at least, you can call yourself "the king of Mobs" and "Notch's dead brother"

One day, Steve and Alex, and Notch, were talking about normal things. And you were watching them from the shadows...oh! And, you're Herobrine, that's why you're "the king of Mobs" and "Notch's dead brother"
