Destroyer of Worlds is an old game installed in the desk of Park Ballroom. This game was owned by the Destroyer of Worlds villain character.
Once, the game spawned real life due to the negligence of Rigby. Rigby pulled off a cloth that had originally covered the game Destroyer Of Worlds, despite a sign declaring that the game was out of order. The Destroyer of Worlds came to life after Rigby and Mordecai read Skips's note, which said: "IN THE NAME OF ALL THAT IS HOLY, DON'T CONNECT THE RED WIRE TO THE BLUE WIRE." In disreguard to this warning, they connect the wires, and a smoky version of the floating devil head appears and flies out of the room, causing the room to briefly encounter a blackout. The light from the game is then illuminated, it generates an explosion of lights , and soon afterwards, the game shows the Destroyer of Worlds (character).
