Entity 303 is the most mysterious part of the StarGate community. He goes by many names, but prefers "303" or just "Entity". He is an expert hacker, bringing himself into many games and destroying them from the inside. He is the half-nemesis of Herobrine and Null, who are both Minecraft "creepypastas". They are sometimes forced to work together, and when they do they are a formidable force.
