Perplexahedron

The Perplexahedron was an artificial cube-shaped planetoid built by Professor Paradox to hold the fourth piece of the Map of Infinity. It was known for being a labyrinth planet and led people into the wrong paths, protecting the Map of Infinity from intruders.
==Appearance==
The Perplexahedron was no different from that of a Rubik's Cube the size of a planet. It's interior was primarily segmented cubes with smaller paper-white cube-shaped rooms.
==History==
===Ultimate Alien===
Ben, Gwen and Kevin were sent to Perplexahedron in Perplexahedron by Azmuth, to find the final piece of the Map of Infinity before Ultimate Aggregor could. Its doors would move to various places, leading the team back to where they once started. Several rooms contained deathtraps. Its doors would also form into a Techno Guard to fight people who come through intact, preventing them from moving on to the next room. It was evident that the guards would appear only to protect the piece of the Map of Infinity as the team got closer to it.
It self-destructed when the piece of the Map of Infinity was given up by the Sentinel (and thus served its purpose), it's base cubes breaking apart until it dissolved into space.

==Etymology==
Perplexahedron is derived from "perplex", which means to confuse, and "hedron", a geometrical term used in the name of solid figures.
==Trivia==
*The idea of Perplexahedron is derived from the 1997 science fiction movie Cube. In the movie, a similar structure is created with identical rooms, some with lethal traps, to prevent its inhabitants from escaping. However, the white appearance of the rooms of Perplexahedron is the same as those of an older movie The Cube, released in 1969.
*Being a large, dark silver cube, Perplexahedron resembles the AllSpark from the 2007 Transformers movie.
