The history in between is like a blank sheet of paper awaiting to be filled, and thus, the supreme God suddenly appeared during this process.
Many things are like this, they emerge suddenly, then unleash their powers. God is the God among gods, and their origin is an anomaly above some era.
Precisely because they are anomalies, gods inherently should not have an "Apocalypse".
But that is only the original state.
Because the first God that appeared already represented this concept of an all-consuming apocalypse, consequently, the subsequent gods have long since met their end — an apocalypse that awaited and appeared before their birth, yet in the "order of events", the apocalypse remains far in the distant future.
"The endless end is not the nihility and elimination of the Blank God! Nor is it the weak timelines of the End of Universe, nor the false demise of Subspace, nor the price demanded by the Gate of Truth!"
