Dimension 1 is the dimension of John Smith, and the origin dimension of the John Smith 10 franchise. It is the prime dimension that is hosted in most John Smith 10 media. This dimension has its own Null Void dimension and Ledgerdomain. Starting with John Smith 10: Phantom Watch, the path of the dimension changes. After the arrival of Phantomin the dimension, it caused a rip in time and space, divulging the prime dimension into two. John Prime returned to this dimension, making it the new prime dimension. Due to this tear, several more godlike monsters were awakened by either Phantom or the space time tear. Such examples are Prometheus, Solaris and Gaia. There is no known John 10,000, due to the future being undetermined.
