Arceus looked down upon the world that he had crafted so long ago. A vast sea covered the planet, broken apart by multiple vibrant green landmasses. A bright blue sky, with clouds of white floating along aimlessly.
It was the first major project that he had undertaken, and considering that it had taken decades to get right, he was quite proud of his handiwork. Not only had he crafted an inhabitable planet, but he had also molded the creatures inhabiting it.
A flash of light drew his attention to the edge of the planet, and he watched from a distance as a certain serpent blasted a meteorite apart. Rayquaza continued to fire its Hyper Beam at the fragments that the meteor created, until he was satisfied that none would hit the world below. Arceus watched as the Dragon-Type circled the area a moment longer, before turning and vanishing behind the clouds.
Gazing upon the world for a moment more, he teleported himself back to the Hall of Origin. A place hidden well beyond time and space, the Hall of Origin was a place where he and his fellow Legendaries could have their rare meetings. But when no meetings were happening, it was where Arceus could do his work in peace.
And for the first time in a while, Arceus had some work to do.
He may be an all powerful Pokemon, but he had a simple job to do. In a nutshell, it was to keep the world from breaking. But alongside that job, he had placed restrictions upon himself.
He could not just invoke cosmic power and fix the world with a wave of his hoof. No matter how easy it would be, it wasn't fair for the inhabitants of the planet.
He could not make an appearance and directly intervene. By showing himself, he would just paint a big target on his head. And after all the years of him being believed to be mere myth by humans, he would rather not have them change their minds now.
And finally, he couldn't just flat out ignore linear time to see the solution. Mainly because he didn't want to cause any paradoxes, but also as a courtesy to Dialga. According to the Dragon of Time, the last time that he had done something of the sort it had given him 'a big headache.'
It was only polite to keep him from getting another migraine.
Keeping those rules in mind, the Alpha Pokemon looked down at the Legendary that had approached him. A Celebi floated towards him, and briefly nodded.
"Lord Arceus, I have a report for you. May I share it with you via telepathy?"
He merely nodded and after a moment, he felt Celebi give him a telepathic package. He reviewed the information within a second, before nodding again towards the Celebi in thanks. Taking its cue, Celebi teleported out of the Hall.
The report was worrying, to say the least. More and more wild Pokemon are becoming restless. Multiple instances have already occurred where a wild Pokemon has attacked humans for no discernable reason.
Meanwhile, throughout the human's civilizations, crime was on the rise. There were multiple hostile organizations on the rise that have been spreading their ideas to others.
Not only that, but quite a few of his fellow Legendaries were some of their targets.
Now, he had to find the solution. He couldn't do his normal course of action, which would be to send one of the Legendaries to take care of the problem. If these groups were hunting for certain Legendaries, it would mean that they are equipped to deal with them. He would not send his fellows to be captured.
But that left him with a problem. If a Legendary couldn't do it, then most other Pokemon couldn't either. It meant that he would have to send a human instead. He had done it before, during a war centuries ago. Two human factions had been fighting in order to capture Mew. He had been forced to choose a hero, to defend the psychic feline. In the end, it was successful, but it had been at the cost of the hero's own life.
He remembered the hero's name, Aaron. Out of respect for him, Mew had his final resting place, the Tree of Beginning, transform the war-torn countryside into a flourishing field of beauty.
In any case though, the problem wasn't choosing a human. The problem was choosing multiple. These groups were spread out across multiple regions, and he couldn't just have a single human hit them one by one. If one organization fell, it would allow the other groups room to grow stronger. He had to make sure each organization fell at roughly the same time.
To put it blunt, he didn't know who to pick. He didn't want to pick the various 'champions', as they could easily reveal his existence with their position. The same went for any of the proficient trainers that were part of the league either.
Arceus didn't want to waste any more time working on a solution. So, silently apologizing to Dialga, he broke time for himself. He traveled to the immediate future, only for a moment, and caught a glimpse of the ones that his future self had chosen.
He quickly returned to the correct position in time, now armed with the information of who he'd pick. He briefly reviewed the five new trainers that his future self had chosen.
The first was a quiet boy, hiding a fierce determination to win. The second, a spoiled boy that would soon have his world turned upside down. The third, a superstitious girl that wanted to gain confidence. The fourth, a boy with a willpower of iron and nerves of steel. And finally, a boy with an incredible gift.
Each one was spread across different regions. If he managed to nudge them all in the right direction, then they would be able to sort out the problem. He didn't want them to suffer a fate like Sir Aaron had. But he knew that even this little bit of intervention was pushing the limit to how much he could alter before other humans, such as ones close to who he had chosen, catch on.
Besides, he had to get ready to speak to the soon-to-be group of trainers. He gazed upon the hall for a moment, before deciding to make some temporary changes.
For starters, he scaled the room, and himself, down to a more appropriate size for speaking to humans. He would still tower over them, but it wouldn't be by a ridiculous amount. He temporarily denied entrance to the Hall, he didn't want anyone to interrupt. He also reeled back the sheer amount of energy that he was giving off, not wanting to overwhelm the young humans.
He made a few more minor adjustments. It had been some time since a human had visited the Hall of Origin, and he wanted to make sure that he was prepared. If he remembered correctly, the last time a human had been here was...when Hoopa had been caught messing around with one.
Chuckling internally, he remembered the scolding that Palkia had given the mischievous Pokemon. Hoopa had made a poor human run through his hoops for 20 minutes straight, and it had only ended when the human in question had run smack into Ho-oh.
It hadn't taken much time at all to work out the culprit. Hoopa was yelled at by quite a few of his fellows, and the human had to be put to sleep by Meloetta. Eventually, they had decided to wipe the memories of the encounter from his mind, and Hoopa reluctantly dropped them off where he had started.
After a few more changes, Arceus decided that the setting was adequate enough to meet with the humans. Knowing that he couldn't delay any longer, he gazed upon each of the humans. It was nighttime for all of them, save for the boy in Unova, where it was midday.
But Arceus wasn't waiting any longer. Breaking his rule of direct intervention, he put the boy to sleep the first moment that he could. With all of them asleep, he was ready. Arceus teleported each of them to the Hall of Origin. Awaking them, he watched as each of them reacted to his presence.
It was actually quite amusing. Two of them fell over, the girl let out a particularly loud yelp, and each one of their eyes were full of shock. The shock was short-lived though, and they each recovered quickly.
They looked upwards at him, and he met each of their gazes individually. Arceus could tell that even though he had turned down his energy output, the trainers were barely holding it together, which was understandable. It wasn't as if a human got to meet him every day.
In any case, he had kept them in suspense long enough. Introducing himself properly, he began their first meeting together.
