Earth was at ground zero of the Planeshift, thus it has elements of the many planes on it. It is unknown just how many different realities were combined on Earth, but the planet is no longer what it once was. Everything from tiny Pokemon to massive Mechs can now be found on it. Earth is under the supervision of The Council, a group of powerful men and women (basically this Earth's Avengers or JLA), but no one currently claims to be the "ruling party."

The Moon is a large body of rock that orbits the Earth. It's origins are unknown, though many scientists believe that it is the remains of a prehistoric collision between the Earth and an extremely massive meteor. Uatu the Watcher calls this astral body his home, watching over the Sol sector. Many intersteller Super-groups have built bases on the surface, but it is currently uninhabited and those bases have degraded.

Asteroid M is an asteroid that was converted by Magneto into his home base in one of the many universes that now make up this reality. In the universe it hails from, Magneto completed it just after recruiting his children into the Brotherhood. The Asteroid has many levels, including an observation deck, hangar bays and medical facilities. It also features teleporters, not unlike those seen in Star Trek, for quick return to the Earth's surface.

Titan is the largest moon of Saturn and the second largest moon in the Sol System, after Jupiter's moon Ganymede. It was discovered by Humanity on March 25, 1655. Titan is the only known moon with a fully developed atmosphere that consists of more than just trace gases. The Titanian atmosphere is more than one and a half times dense than Earth's and supports an opaque cloud layer that obscures Titan's surface features. It is thought that Titan may possess bodies of liquid ethane. Due to these facts, the Titans built their civilization below the surface of the planet.

The Transformers homeworld. "Cyber": a prefix denoting a computerized origin, a computer, a computer network. "Tron": an acronym defined as "the real-time operating system nucleus". The planet is approximately 98% technological; only the core of the planet is still organic in origin.

Otherworld is the legendary land known in Earthian folklore as Avalon, the home of the Celtic Gods. Characters such as Merlyn, Arthur Pendragon, and the Lady of the Lake also call Otherworld their home. Dragons, elves, fairies, giants, goblins, and other similar "magical" beings can also be found in abundance here. Otherworld can only be accessed by magical means or time travel.

A hellish planet currently ruled by the evil Darkseid, Apokolips is not a place you would want to call home. Good and pleasant things find it hard to survive on this planet, which has very few green plants growing on its surface, which is mostly covered with burnt-out craters and industrial centers where the "Hunger Dogs" slave away for their cruel master.

Space, a long cold dark frontier awaiting someone to conquer it.
