Pocket Universe

Pocket Universe are realities created by a single being that tend to be normally smaller than the true world and have a certain lack of reality.
One of the largest Pocket Universes was DC's Earth-Twenty-Three. It was created by the Time Trapper by making a copy of the main DC universe as it existed 1 million years ago and "pruning" it down to two populated planets: Earth and Krypton.
