heres the (leaked) origin of the pokemon universe story with the correct pokemon names in place of the beta ones
(original text here)
EDIT: just woke up but theres an updated translated version here. I've gone ahead and changed the text below to the updated version
Please note that there is no mention of giratina in the updated version (which makes more sense based on some other info we have)
In the beginning, there was a vortex of chaos.
All mixed slowly together, and everything was a blur.
One day, a large egg appeared in the center of the chaos. For a long time, the egg continued to shake.
Eventually, the vortex stopped, and the egg broke. The absolute god Arceus was born.
The scattered fragments of the egg transformed into giants, and attacked the newly born Arceus.
However, Arceus quickly grew, and continuously defeated the giants.
At last, after a fierce battle, Arceus defeated all the giants.
The wounded Arceus created an alternate self.
As the left and right side of Arceus’s body were different, it created two selves.
Arceus gathered the body of the defeated giants, and poured its blood into them.
From the one who resembled his left poured out light, so Arceus named it Palkia, the god of light.
From the one who resembled his right poured out darkness, so Arceus named it Dialga, the god of darkness.
To the two, Arceus commanded that the world be filled with people, and fell into a deep slumber.
Although Palkia and Dialga were different in appearance, they loved one another, were joined, and had many children.
However, there still existed no world, and their frail children, who had nowhere to go, died one after the other.
Though overcome with great sadness, Palkia and Dialga thought of creating a world where all could live healthy and prosperous lives.
Palkia and Dialga called their children Uxie, the god of eyes; Mesprit, the god of heart; and Azelf, the god of voice.
When Uxie open its eyes, everything that was there appeared. There was now contour and color in the world.
When Mesprit wished for it, everything that was there could be felt. A sense of calm spread.
When Azelf shouted, everything that was there trembled. A blessed timbre began to resonate.
To the three, Palkia and Dialga gave the seed of life and told them to nurture it.
The three gathered in a circle and prayed, and the seed sprouted.
The sprout quickly grew, and became the giant tree of life.
However, the tree continued to grow, soon filling the entire world, and no one was able to move.
The three asked Father Palkia and Mother Dialga for help.
Dialga and Palkia joined once again, and had three children.
The god of the sky, RAYQUAZA; the god of the earth, GROUDON; and the god of the ocean, KYOGRE were born.
RAYQUAZA wrapped its body around the tree of life.
GROUDON and KYOGRE slammed their bodies into the tree of life.
Eventually, the tree fell and broke into three pieces.
Uxie, Mesprit, and Azelf prayed, saddened that the tree would rot away like this.
Then, the pieces of the broken tree would transform into the sky, earth, and ocean.
RAYQUAZA became the pillar that holds the sky.
The shadow that reached into the heavens became the three gods who sustain the sky: Dragonite, Gyarados, and Tyranitar.
The air filled the sky, and the stars sparkled.
GROUDON became the land that covers the earth.
The roar of the diving land became the three gods who sustain the earth: DAABU, SAAN, and GOODON.
The earth shook, and the mountains stirred.
KYOGRE became the veins of water that embraced the oceans.
The ripples that disappeared into the seas became the three gods who sustain the ocean: LATIAS, METAGROSS, and LATIOS.
The ocean was filled with water, and the waves whispered.
Thus the world was born.
Palkia and Dialga, and the various gods, were very pleased with this, and filled this world with their children.
That peaceful world was a paradise for the children of god.
The children of god would continue to multiply.
Through that, words would change little by little.
Over time, the gods began would call those who lived in the world by two names.
The children of god who resembled the great father, Palkia, would be called “Pokémon”. The children of god who resembled the great mother, Dialga, were called “humans”.
The absolute god Arceus will soon awaken, and seeing the world filled with its descendants, will promise great abundance and prosperity.
These creatures are just redesigns of Uxie, Mesprit, and Azelf. I based this picture off of this post here, which is also where I got the Pokémon universe origins.
