Looks like Webnovel strikes again with its young master temp (retarded).

Calyrex
There are numeral Origin Pokemon if considering approximately 10 to be numerous.
Arceus decided to target those that are still growing rather than those that have stagnated. Anyone else can be dealt with steadily.
Those that are still growing are few. Specifically, 3.
Calyrex, Kyurem, and Regigigas.
Zacian and Zamazenta had counted, but well... you already know why.
Arceus decided to start with Calyrex, a Grass Psychic type, that focuses on Life energy.
With Life energy's broad range of possibilities, Calryex focuses more on its healing aspect. When it comes to healing, short and long-term, Calyrex is the best Pokemon out there.
Its combat ability isn't weak either, proof being its battle against Kyurem. Although it didn't win that fight, it had managed to last 10 months before being forced to retreat. Then again, Calyrex is a support and not a fighter.
He can teach almost anything with his biggest focus being on Runes, excluding Arceus and Adam, Calyrex is indeed the best Rune user out there. The fact that he's semi-Omnisicient thanks to Ominsicient (Low-Expert), makes it rather impossible to defeat him.
Unlike Arceus, he uses it.
This is also why, he quickly surrender to Arceus, allowing him to seal his Origin before Arceus could even start executing his plan.
Arceus intended to take advantage of the fact that Calyrex refused to stop using his Omniscient to get rid of him permanently. However, with Calyrex surrendering himself before that, Arceus readjusted his plans.
Calyrex can still be recycled, before removal and he can do the same with the rest.

I have wasted your time enough, let's get to the climax of this arc.
***
It's a strange sight watching a Deoxys and a Ralts chat together watching Poketube on a phone in the sky.
Medusa had long since smacked Mike and began her adventure, especially after confirming Mike won't leave anytime soon. No longer containing her excitement, Medusa was ready to explore the first interesting place she noticed.
Pity, Mike didn't come with her, he had already proven just how good he was at being a better trouble magnet than her.
Ready to teleport over, Medusa quickly sensed an even more interesting sighting and teleported over.
Arriving high in the sky, from the looks of things, she's still in Alola, more precisely a man-made island (Aether Foundation). Just looking at the artificial island, Medusa's eyes twinkled with excitement. This is definitely a place worth exploring. However, her Universal Traveler Uber ability makes her aware the island itself isn't what's interesting.
With a joyful expression, space fold around her concealing her body as she decisively flies down to explore these island. Slowly but enjoyably.
'Humansss,' Medusa thought, silently observing these two groups of humans before shaking her head disappointedly.
'Boringsss,' Their conflict doesn't seem interesting enough and their attire wasn't any better. One group is in all white and another with a big R on their shirt.
Not wanting to waste time any further, Medusa continued forward letting her Universal Traveler take her to the most interesting part of this place.
...
"Hi everyone, it's me Professor Bradford, and welcome back to my Poketube channel, Courage Wilderness," Professor Bradford announces, standing on a white paved ground, the background focusing on the large building behind him.
Bluebluebulba: Where did you 'legally' arrive at this time?
SuperNerd: There are not many places left that welcome him legally, but that's his own fault. Not many of those places wouldn't welcome you.
"Even if they did welcome me, I didn't come to be a tourist. I'm here to see the truth!" Professor Bradford said emotionally.
YoungsterJoey: Reshiram nods its head in understanding.
Bluebluebulba: He's also being idealistic, assuming he won't get arrested this time. Making Zekrom also nod his head.
Nunster: His EQ is as empty as a Sheninja's insides. Kyurem additionally nods.
"*cough* Anyways, can you guess where I'm?"
GothatD: Aether Foundation. Got to say, you're one big trouble magnet.
SuperNerd: Oh? What insider information do you have?
GothatD: We had a great business deal with big R recently, and let's just say they are here.
HardenItUp: Smooth...
GothatD: Not like anyone can stop them right now.
Ash'sTheBest: There's still Ash.
SuperNerd: Indeed, there's still Iris.
HardenItUp: Through, a champion is still around.
Ash'sTheBest: You guys...
"Big R, Big R, Big R..." Professor Bradford recited. "Oh ****! Team Rocket!" He exclaimed.
YoungsterJoey: You have been censored!
*roar*
In the sky, one can see a group of Pokemons flying towards Aether Foundation their riders...
"Kids?"
Ash'sTheBest: Ash's here.
A Dragon Pulse tore a hole into the ceiling, into which their Pokemons flew.
...
"FInallysss" Medusa accidentally hisses aloud.
Causing the blond hair woman and the mafia man with the R logo to turn to face her. Of course, they can't see her but only fools wouldn't have heard that noise (cry in their perspective).
Realizing it's now pointless to keep hiding and the fact that two were far from threatening, Medusa revealed herself, doing her best to show she's harmless.
She doesn't want to harm these two, not when they will sooner or later bring forth the entertainment seen her Universal Traveler has been telling her.
Though cautious, seeing as this unknown Pokemon hadn't attacked they surprisingly return their focus to each other, causing Medusa to sigh in relief.
Luckily her Unfocused Reality saves her a lot of trouble, the second they had turned to face each other ignoring her, they could no longer sense her presence and deemed it as her left. Taking this chance, she quickly made herself invisible once more before focusing back on them.
"What is it that you want, Giovanni?" Lusamine asks cautiously, her Pokeball tightly held in her hand.
"Beedrill Fell Stinger," Giovanni said, completely ignoring her, turning his gaze to the Cosmoem that was strapped to a machine.
"Don't tell me you plan to..." With astonishing speed a Beedrill appears behind Lusamine, its lance-like hand pierces a hole into her stomach causing her to fall to the ground unconscious.
"Grunts, patch her up. It's far too early for her to die," Giovanni said, causing Rainbow Rocket grunts to immediately enter the room and drag her out.
Giovanni needs to move quickly, he had purposely held back his Pokemon's strength just for the day when the war begins and all Guardian Pokemons are preoccupied.
Though his goal had changed, the methods and planned don't need to change.
This time it'll be humanity's victory.

2-3 chapters before this arc end and the last arc of this volume starts.
Again, this arc was mostly to get information for both you and Mike.
