For accurate info, see the Ben 10 Planet page.
The Perplexahedron resembles a large cube-shaped planet. It is silver on the outside with an incountable amount of rooms within. The rooms are large and white with a grid of lines. There are also doors that open in the walls. It is seemingly never-ending and nearly impossible to escape as they hallways lead to different rooms and sometimes back where you started. The planet itself resembles a maze or a labyrinth planet.
- The Perplexahedron was created by Professor Paradox
- Although the Perplexahedron was destroyed in the canon series, it still exists in other universes/dimensions/timelines.
