Multiverse

Overview
A Multiverse is a set of an infinite amount of universes. All of them are almost the same, but each one of them has one or more changes in what happened from the Big Bang to today. These changes can be simple (for example, if you yesterday ate pizza, in another universe you may have eaten sushi) or major (for example, Hitler won WWII in one of the universes). Due to the huge amount of changes that there can be, the universes would be more than infinite, and thus the multiverse is bigger than infinity.

Our multiverse exists in 6 dimensions, meaning that it covers every possible scenario as described above but with a limitation: every universe has a common origin, the Big Bang. The Megaverse contains all the multiverses considering each one of them starts in a different way.

There are many universes on different Reality Planes, and a person possessing 5th dimensional powers is able to coexist in every reality plane depending on how many Reality Planes exist in a determined Multiverse.
