3 YEARS LATER

Three long years had passed since Ash had discovered Mew by pure chance and in that time they had become fast friends. Ash had kept Mew secret for a long time and hadn't told anyone of her existence here in Pallet for fear of rabid researchers coming to get her. Honestly when Ash went to get his Pokédex and Pokéballs he would tell Professor Oak that he had a Pokémon friend in the forest and was going to make it his new Pokémon.

He couldn't wait to see the look on Professor Oak's fast; unfortunately, it wouldn't be for a while because as soon as Ash would make the capture he was going to have Mew use Teleport so they could leave Pallet Town.

In the three years since meeting Mew Ash had also been training with her to help her get stronger since he found out that she was quite young; about a year and a half old when he first met her and that was incredibly young by Pokémon standards.

Right now it was almost time for Ash to go to bed; he lied in his bed staring up at the ceiling for a bit with his arms crossed behind his head. 'Tomorrow is the day' he thought. 'Tomorrow I begin my Pokémon journey... but where should I start? I know Mew wants to be a member of my team, but with her on my team we'll be targets. I know there are many Pokémon thieves out there that would love to get their hands on her, but... can I protect her alone with my power.'

Ash turned over and saw his favorite book 'Pokémon Legends and Origins' and he stared at it for a moment before his eyes widened. Quickly Ash sat up and grabbed the book flipping through the book seeing many pictures of Legendary Pokémon across the Seven Regions.

'That's it' he thought. 'Pokémon trainers across the world have kept trying to capture Legendary Pokémon and to date two, maybe three in all of history have even captured one, but I'm the first one who started out with one. Maybe... maybe I can be the first one to capture them all.'

With that thought in mind Ash fell asleep dreaming of his future.

(TIME SKIP LIKE A BOSS)

In the morning Ash woke up to a little weight on his chest. He looked down and saw Mew sleeping peacefully on his chest. Ash smiled and gently stroked her fur along her back; after a few minutes Mew woke up with a delightful purr.

"Today's the big day Mew" Ash said. Mew squealed with excitement and did a cartwheel in the air making Ash laugh. "I just got to make a quick trip to Professor Oak's lab and then we can get going" he smiled. Mew nodded and lied back down while Ash got changed into a pair of shiny red tennis shoes, black jeans, a plain white undershirt and a long sleeved blue V-neck shirt with black tribal markings. On his head he wore a red cap with a blue pokéball design in the middle. Once dressed he went downstairs and ate breakfast with his mother, who was a little concerned that Ash didn't seem worried about being over an hour late.

"Honey shouldn't you be at Professor Oak's lab by now" Delia asked.

Ash looked at the clock "Oh would you look at the time" he mused. "See ya mom" he waved before racing out the door. Delia blinked at her son's actions.

Ash simply walked at a leisurely place to Professor Oak's laboratory and it took him about ten minutes to get there. When he did he noticed a crowd already outside the lab along with a row of cheerleaders and immediately Ash knew who they were all here for.

"Well, well if it isn't Ashy-boy" a nasally mocking voice said. Ash saw it came from a boy his age with an arrogant smirk and spiky red hair.

"Gary" Ash greeted in a calm voice.

"Well Ashy-boy you snooze you lose apparently" Gary said with a smirk "I got a Pokémon and you don't."

"Mm-hmm" Ash hummed.

"And it's right here in this Powerball" Gary said spinning the pokéball on his finger.

"Neat" Ash said uninterested.

Gary frowned at Ash's lack of reaction "Well good luck at getting a Pokémon; I'm already ahead of you. Let's go ladies." And with that Gary and his posy left area. Ash shook his head at his old friend's arrogance; it seems that Gary hadn't changed at all.

"Oh there you are Ash" Professor Oak said from behind him.

Ash turned and greeted the kind professor "Morning Professor I'm here to start my journey."

"Well you are pretty late; I don't think I have any Pokémon left" Professor Oak said.

"Oh that's okay; I just need some Pokéballs and a Pokédex" Ash said.

Professor Oak blinked "Um Ash, you need a starter Pokémon to begin your journey. You know that right."

"I know that" Ash said with an easygoing smile. "It's just that I befriended a Pokémon three years ago and I've remained friends with it in the wild ever since. I promised that Pokémon that it could become my starter Pokémon."

"Oh" Professor Oak said interested. "Could I see it?"

"Ah, ah it's a surprise" Ash said with a grin.

Professor Oak laughed "Very well; I do love surprises." With that the old professor pulled out some pokéballs and a Pokédex "Here you go Ash."

"Thank you Professor" Ash said pocketing the Pokéballs. He scanned the Pokédex "Hey professor, if at all possible could you update the Pokédex with information on the Pokémon from the other five regions?"

Professor Oak blinked "Sure, it's no trouble, but why do you want to update?"

"I plan on taking a few trips to the other regions to expand my Pokémon team. I mean when I eventually get enough badges not everyone, especially Gary, well expect Pokémon from another region."

"Clever Ash" Professor Oak said pressing a few buttons on the Pokédex "Alright you're all set."

Ash took the Pokédex back "Thanks Professor Oak" he said before he raced off into the distance heading back home. Once he got home it was an emotional moment with his mom, who couldn't believe her 'little boy' was all grown up now. Thankfully no one was around otherwise Ash would've been truly embarrassed at all the things his mother had packed for him as well as a reminder to change his 'you know what' every day.

Once Ash now had his stuff he went outside and once he cleared the house he called out "Mew" and in a flash the New Species Pokémon appeared. "Alright Mew, we're ready to start our journey at last." Mew nodded with a purr and Ash pulled out a pokéball. Mew eyed it wearily "It's just for an official capture Mew; you wouldn't want anyone else to capture you would you?" Mew violently shook her head appalled at the thought of being captured by anyone other than Ash. "So it'll just be for a quick moment." Mew nodded hesitantly and Ash gently tapped the pokéball to her forehead and she vanished into the pokéball. The pokéball in Ash's hand barely shook at all while it blinked and a few seconds later it dinged showing a successful capture.

Immediately after the capture Mew popped back out shaking her head like a cat who just got ruffled "You don't like it in there" he asked. Mew shook her head "Well then I suppose I can keep you out of your pokéball while we're travelling, but when we're in a populated area you have to stay invisible or transform, whichever you choose." Mew nodded in understanding "Also Mew there will be some instances where you must return to your Pokeball, not many, but some, okay" he said gently. Mew nodded again, this time more hesitantly. "Okay, then let's get our journey started."

Mew cheered along with her new trainer.
