Perplexahedron is a artificial Cube shaped planet that held A piece of the Map of Infinity. It's known for being a maze-like planet, and leads people into the wrong paths, protecting the Map of Infinity from others. Its doors will move to various places, leading people back to where they once started from. Its doors will also form into a guard to fight people who come intact, preventing them from moving on to the next room. It was revealed that for them to be called 'Guards' they must be guarding something. It was evident that the guards would appear only to protect Map of Infinity as you got closer to it.
