At first, there was nothing
Then, out of all the chaos of space, time and Dark Energy, there came to be an Egg.
The being hatched from the egg was know as Magikarp.
Magikarp then created the being known as Arceus, from absolutely nothing but pure will, and charged it with bringing order to the Chaos.
And Arceus in turn created 3 great beings, Dailga in charge of Time, Palkia in charge of Space, and Giratina in charge of Dark Energy.
And Dialga and Palkia, working together, created the universe we exist in.
And Magikarp saw that it was good.
Then Magikarp created many other great beings, Ho-oh, Lugia, Kyogre, Groudon, Rayquaza, and many other great beings, who were all put in-charge to fill the empty Universe that Dailga and Palkia has created.
Kyogre created the waters, Groudon created the lands, Rayquaza shaped it all into a single body held together by gravitational forces.
And Magikarp saw that it was good.
And Ho-oh and Lugia created life.
Ho-oh created powerful elemental beings to watch over the land, while Lugia created powerful mystical beings to watch over the waters.
They then created one being together, its name did not survive the test of time, but it had the ability to change, to evolve, to multiply into completely different creatures, and all creatures in this world were once part of this being.
And Magikarp saw that it was good.
Satisfied with all that is, Magikarp divided into innumerable copies of itself, each copy having no powers of its original self, just to act as a final testimony of its own existence and purpose. These copies were sent into the many great seas and oceans, rivers and lakes of the new world, so that it may forever be remembered by its creations.
And finally, Magikarp saw that all was well.
It finally leaves the completed world, never to return, trusting that its creations would be a great testimony to itself in the new Universe.
