Kanto

A boy can be seen walking towards professor cerise's lab as he opens the door and looks for the professor

Arthur (L/n) blackdeath: the son of adrian blackdeath

Arthur: hello? professor cerise? Are you there?

Arthur looks for professor cerise and he finds him

Professor cerise

Cerise: arthur? What brings you here?

Arthur: hey professor i was wondering if its okay for this to be here

Arthur pulls out a pokemon egg suprising the professor

Cerise: a pokemon egg! it seems like you found one!

Arthur: yeah, i actually found it while trying to find more pokemon so is it alright for the egg to be here?

Cerise: of course arthur, ill let you know when its gonan hatch

Arthur nods and went to the pokemon dome and sees two individuals and he goes to them

Ash ketchum: alola champion & goh

Arthur: hey ash, hey pikachu, hey goh watcha got there

Pikachu: pika!

Ash: hey arthur! Yamper found a leaf stone for goh here so he used it on exeggutor but what are you holding

Ash and goh look at what arthur was holding

Ash: no way...you got a pokemon egg aswell

Arthur: you have a pokemon egg aswell?

Ash: yeah but it hatched and i got a riolu (its just like big bro's riolu)

Arthur: i really like riolu but maybe its something else (i better get him out of vacation he's been staying in alola for too long now)

Arthur looks at the exeggutor and he remembers something

Arthur: now that you mention it i remember the exeggutor in alola are bigger than the ones here

Goh: really?

Ash: yeah, theyre really big!

Goh: whoa...

Cerise: why dont you three go to the alola region get a sense of the place and catch all you can

Arthur: i was planning on going to alola since i have to get teach off his vacation

Ash: you have a teacher?

Arthur: oh right you didnt know, ash i have a mentor who actually helps me train my pokemon but....*starts shivering* the training regimes were literal chaos

Goh: well....what are we waiting for, lets go to alola!

Arthur: *sigh* come on ash lets go

Ash: right, yamper take care of the place while where gone

Ash/goh: alola's waiting...lets go!

Arthur: i guess alola should be fun

Alola

A young man can be seen wandering around alola with his lucario and a riolu with them and he's thinking right now

(Y/n) ketchum: kanto champion, legendary pokemon trainer

(Y/n): hmm should i stay in alola, i should ask arthur about it

His phone suddenly rings and he sees who it is

Rotom phone: your apprentice just messaged and he said he's going with your little brother in alola

(Y/n: wait what?

Rotom phone: yep he's arriving tomorrow

(Y/n): this is gonna be a problem, we havent seen ash for 8 years now right lucario?

Lucario nods and he looks at his rotom phone and he sees......arthur and he had an annoyed expression until (Y/n) notices it

(Y/n): are you still mad because of that prank?

Lucario: lucario!

Rotom phone: at least just get over it considering you yeeted arthur in the sky for pranking you

(Y/n): i went to unova just to meet roxie then i look away for ten secends seeing you yeet him off

Lucario huffed and looked at (Y/n) and he knew that look

(Y/n): i know partner, dont worry ill find meet him and give riolu to arthur and i hope you'll be great friends with him riolu

Riolu: riolu!

Riolu was happy to hear that and (Y/n) kneels and pat its head

(Y/n): come on you two lets relax for a bit back at the hotel and after that lets go to back home to pallet town

Both lucario and riolu nod on their way back to relax in their hotel room

Timeskip to chibi (Y/n) playing the guitar while singing idfc by blackbear

Arthur, ash, pikachu, raboot and goh finally arrived in alola then someone calls ash

Professor kukui

???: ash over here!

Ash: professor kukui!

Goh: wait up!

Arthur: (so thats professor kukui, i guess this is the person teach considers a father figure)

Ash: alola professor kukui

Kukui: well alola ash, welcome home

Ash: *smiles* we made it

Pikachu: pika!

Kukui: and pikachu you look great!

Pikachu hops on professor kukui's shoulder happily

Goh: hey dont run off without me, how am i gonna introduce myself

Arthur: at least let ash have a reunion goh

Ash: uh sorry goh, thats professor kukui, he teaches at the pokemon school here in alola, hey where's professor brunet?

Kukui: she's waiting for us at home

Ash: awesome!

Goh looks at ash confused

Ash: they were our family in alola, we lived in their house

Kukui: you must be arthur and goh alola

Goh: alola

Arthur: alola professor kukui

Sobble goes at raboot's head

Kukui: whoa! Thats raboot and sobble! its the first tine ive seen them in real life!, so did you catch them in the galar region

Goh: uh yeah

Kukui: i bet you can deliver some powerful kicks raboot

Raboot: raboot...

Kukui: and you sobble, you must really trust goh he must be taking good care of you

Arthur: (i wonder what teach is doing right now)

Meanwhile with (Y/n)

(Y/n) sneezes and looks around and his pokemon looks at him

Latios: are you sick?

(Y/n): im fine latios, i feel like someone is calling for me?

Latios: it must be arthur

(Y/n): your probably right

Back to them

They arrived at professor kukui's house

Ash: im home!

Professor brunet opens the door with a baby in her arms

Professor brunet & lei

Brunet: welcome back you two!

Ash: alola professor brunet, and this is lei right

brunet: thats right, big brother

Ash: big brother...

Ash holds lei's hand

Ash: nice to meet you lei, your hands are tiny

Lei starts tapping ash's face

Brunet: now now lei your doing what you did to your other big brother

Lei stops and ash looks confused

Ash: other big brother?

Brunet: oh thats right, you never met him yet his name is (Y/n) he's also lei's big brother

Ash was shocked but he wanted to find out if it was him

Ash: um professor brunet can i ask you something, does he have a riolu or a lucario with him

Brunet: he does have a lucario, how do you know about (Y/n) ash?

Ash realizes it was really him he decided to tell them

Ash: (Y/n)'s my big brother

Professor brunet was suprised by this considering he would act weird if she mentions ash when he's around since he would go quiet

Brunet: i see, but anyways come inside goh

Goh: uh thanks for letting me in

Professor kukui looks at ash and smiles at him

Kukui: so (Y/n) is your big brother huh im glad lei has him and you ash

Ash: i know professor i still miss (Y/n) but i know he's fine probably on a journey

Kukui: i know ash, i know

Goh: um ash...where's arthur?

Ash: huh i though he was behind you?

Raboot walked over to ash and gives him a note and it says "sorry i had to leave you guys i have to get teach of his vacation now -arthur-

Meanwhile with arthur

Arthur can be seen at a hotel and he knocks on the door and (Y/n) comes out with his casual clothing

(Y/n): oh your here, are you improving?

Arthur: yes i am dont worry

(Y/n): good and how's the pokemon egg you found

Arthur: its on professor cerise's labratory......wait how do you know i have a pokemon egg?

Arthur: do you know how little...that narrows it down

(Y/n): yep

Arthur: *sigh* when are you gonna meet ash

(Y/n) stayed silent and just drank some of his coffee and arthur sighs

Arthur: one brother reunion wouldnt hurt teach

Arthur: why?

Arthur groans and decided to drink some water and he just looked at him

(Y/n): 5 years, 8 months and 14 days

Arthur:.................wow i didnt know you counted it

(Y/n): *sigh* you can use the room if you want here's the keys

(Y/n) hands him over the hotel keys and decided to leave but he stops

(Y/n): stay or not

Arthur: what?

(Y/n): i want your opinion, should we live in alola or somewhere else

Arthur: i explored a bit here and.....maybe we should stay in alola if we have time

(Y/n) decides to leave the room and he smiles a bit without arthur noticing

Arthur: can you at least smile?

(Y/n): no

Arthur: please

(Y/n): no

Arthur: at least once!

(Y/n): never in a million years i would smile in front of you (if its serena.....maybe i would)

Arthur: i always wondered why i evolved your shiny thyplosion, decidueye, samurott, arcanine, zoroark, liligan in there hisuian forms

(Y/n): because you respect me and im a different version of your dad

Arthur: fair point

(Y/n) closes the door and starts reading a book about hisuian

(Y/n):....*sigh* after this i should visit the cerulean gym probably meet misty or brock since i havent seen them after that snowstorm

(Y/n) keeps walking and he goes outside and takes out latios

(Y/n): hey bud, ready for to fly

Latios: anything to set out and enjoy the air, where to (Y/n)?

(Y/n):..........lets go to the pokemon school and visit the students i have a feeling ash is there

Latios taks off and both of them head to the pokemon school
