By that time there were already humans on earth, and Regigigas had ended putting the continents in place and retreated itself to the norther place on earth, meanwhile Giratina had finished it's army of monsters and was ready to unleash war on the galaxy, so it looked for a place to get the attention of Arceus and so it took earth as a perfect place to do both do war and create its kingdom when the battle end.
So it was that Giratina and its army of ghosts went down to earth and started to cause havoc on the first humans in history, this caught the attention of not only Arceus but of Dialga and Palkia too, and that was just the exact same thing that Giratina wanted them to do so it could get revenge on the three of them, suddenly the sky turn black and the weather began to get a lot more violent than it was and two sphere of light came down from heaven, and out of them came Dialga and Palkia, Giratina using shadow force appear instantly in front of them and by roaring started the war, at that same moment all of the pokemon from earth commanded by most ancient pokemon from earth, Mew, went to battle against the ghost pokemon from Giratina commanded by Darkrai it was the most violent battle in recorded history, mean while at the top of the tallest mountain on earth a battle had began, Giratina used Will-O-Wisp on Dialga and Palkia thos burning them in the process, Dialga and Palkia using Roar of Time and Spacial Rend respectively attacked Giratina, causing it to fall down to the temple created by the humans at the top of the mountain, at the same time Darkrai summoned its secret weapon to finally crush the rebellion force of Mew and the other pokemons, a very bright light came out of its hands and suddenly the colossal pokemon Regigigas came to battle and with just a punch to the floor it created a huge earthquake taking out half of Mew’s army.
Meanwhile on sky the battle continued, now Giratina was trap between Dialga and Palkia, the two pokemon attack it with their respective moves and Giratina using shadow force vanished thos making the two pokemon received their attacks, Dialga became enraged with Palkia and the two gods began to fight each other, giving Giratina the opportunity to attack them simultaneously and finally defeating them, at the same time Darkrai with the help of Regigigas had won the battle against Mew and it's pokemons.
Just when Giratina was about to announce it’s triumph a thunderous roar interrupt it and a glowing sphere of light came down from the heavens above, Giratina knew instantly what was this sphere of light, humans and pokemon alike stayed where they were without moving a finger, just standing there looking up.
Dialga and Palkia stood up and flew to the light but couldn't get to close to it and from the sphere Arceus came out, Giratina seeying its opportunity went directly to attack it and Arceus making another huge roar began to glow and all of a sudden great bolts of lights began to come down from heaven taking Giratina, Palkia & Dialga down and paralyzing them, Arceus then took out half of their power and sealed it away into three different gems, the Lustrous Orb, the Adamant Orb, and the Platinum Orb, sent Giratina to the reverse world again, and sent Dialga and Palkia to their respective dimensions, it then look down and revive all the pokemon that perished on the war and lock Darkrai away in a small island letting it free only the nights of new moon, and to prevent that it cause more trouble created another pokemon to stop it whenever Darkrai is free, furthermore this pokemon can be free the nights of crescent moon and can create good dreams for humans as opposite to Darkrai, and placed this pokemon on a island aside from Darkrai’s island.
And took Regigigas and sealed it away inside a temple and put a huge glacier in front of it to prevent its scape, also gave the humans materials to create three different keys to sealed them away too making Regigigas impossible to scape if those three keys aren't reunited, and finally created another creature to reestablish nature to where it as before the battle and all humans will have to be “GRATEFUL” to it for that.
And by doing this he roared one more time and disappear in the sky, Writing Giratina, Regigigas, Darkrai, and that battle off history but not from the mind of humans, up in the heavens Arceus look down to earth and realizing that it could be needed one more time it went to the very top of the now in ruins temple and fall into a never-ending sleep.
THE END
