"So you want to tell me where I am?" Naruto asked the Sage as he appeared in a forest somewhere. There was no answer. "Hello? Old man? Guess he's really gone." He looked around. The trees were mostly the leafy types that he had seen growing up around Konoha. "Could it have failed? And I'd made such a good exit, too." He turned around and came face to upside-down face with a small, pink flying cat. "Guess it did work."

What worked? He heard an echo in his mind. It was a pretty familiar feeling.

"Was that you?" He asked the cat. Its eyes turned into the classic eye-smiles and it nodded frantically.

Who are you?

"My name's Naruto. Um, not to be rude… but what are you?"

I'm Mew. The pink cat made a few loops. And I'm a Pokémon.

"A what?"

You're not from around here. The Mew tilted its head. Do you know you're in a different dimension?

"Well, that was sort of the point"

Oh. Ok then. Pokémon are beings like me, with special abilities. Wanna play?

"Maybe later."

Ok. Wanna be the Chosen One who will help bring balance to the world?

"No."

No? The Mew tilted its head. Why not?

"I've been a Chosen One for another world already, it's a lot more trouble than it's worth. I'd just like to live a normal life here."

Ok. Go that way and look for a Samuel Oak. He's a good guy, you can trust him.

"Thank you, Mew." Naruto nodded and started walking in the direction the Mew had indicated.

Shame. I could've really used him. Mew scratched her chin in thought. Oh well, guess I'll just have to wait a generation. I still have time until papa wakes up. Back to the Tree.

Samuel Oak, or rather, Professor Oak, was a researcher based in Pallet town. Truthfully, he wasn't a researcher all that long actually, maybe clocking in two or three years. He had decided to retire from being an active trainer to better understand the wonderful world of Pokémon.

But all his various experiences couldn't prepare him for a blonde man claiming to be a dimension-hopping ninja.

"Another dimension?"

"Yup."

"Are you sure?"

"Pretty sure, since there's no Pokémon in my world." Naruto absentmindedly scratched a large orange dog that was lying next to his chair. "I would've remember something like…"

"Arcanine."

"Right."

"And why come to me?"

"A strange floating pink cat told me to." If Naruto had understood the significance of that sentence, he could've been accused of waiting until the Professor was taking a sip from a glass. As it was, it was just a lucky coincidence that the man choked on the water and spat it out all over the poor canine Pokémon.

"A MEW!"

"Yeah, that was the name."

"Well why didn't you say so. That's changes everything."

"It does? You've been staring at me like I was crazy for a good hour, but one pink cat changes everything?"

"No human could possibly have the power to travel between dimensions. Mew, however, is…"

"Ah!" Naruto raised a hand. "I'm gonna stop you right there. I won't be going anywhere for the foreseeable future, so there will be plenty of time for me to learn. For now I'd just like to grab a bite to eat and then take a nap."

"Well, that's fair, I guess." Professor Oak stoop up and walked to the door. "Delia?"

"Yes Professor?"

"Would you make some food for our guest while I find him a spare bed?"

"Of course. Just a second."

A few seconds later the door opened and a girl walked in. She was a few inches shorter than Naruto, dressed in a green checkered shirt and denim shorts, her hazelnut hair tied in two pigtails. She was carrying a tray in her hands. And she was the most beautiful girl Naruto had ever seen.

"Naruto, this is Delia Ketchum, my research assistant."

"Hello there." She sent a kind smile his way.

A day ago, Naruto was prepared to claim that nothing good ever happened to him. Now he wasn't so sure.

A tenth birthday was an important event. The following spring a boy (or girl, of course) would get their starter Pokémon and go off on a grand adventure all across the world. The Professors for the respective regions were the ones who would give out the starters, and in Kanto, in Pallet town, that was Professor Oak.

This year there were four children that were supposed to come by his lab at 9 AM. It was now noon and three of the four had already been by and taken the only three starters he had.

In hindsight, maybe he could've planned that a little better.

"Professor! Professor wait." Oak sighed when he heard the voice.

"I'm not surprised he slept in." He murmured to himself as he opened the door to his lab, just in time to stop the ten-year-old from barreling into it. "Not at all. Good morning Ash."

"Mornin' Professor." Ash groaned from the heap on the floor. "I'm here to pick up my starter."

"I can see that. Is your father here, by any chance?" The kid's eyes turned downcast in an instant. "I see. Don't worry, I'm sure he's alright."

"Of course he is. Dad's too awesome to get hurt." Oak chuckled. The father had said the same thing verbatim a few years before. "But anyway, can I get that Pokémon now?"

"Huh? Oh, of course. Please." The professor motioned to the machine with three Pokéballs inside it.

"I've been thinking long and hard yesterday, and I've chosen… Bulbasaur!" The Pokéball was empty.

"Bulbasaur was already chosen by someone who was here on time. Ash..."

"Then I'll take Charmander." That Pokéball was also empty. Oak sweat dropped at the slightly panicking teen.

"Also taken by someone who was here on time. Ash, listen…"

"No, don't tell me, Squirtle can't be…" Also empty.

"Gary took it just a few moments ago. Look, Ash…"

"No! How could this happen?" The boy feel to his knees in tears. "Why'd I have to sleep in today of all days?"

"ASH!"

"Yes Professor?"

"Like I was saying!" Oak glared at the sheepish boy and pressed a button on the side of the machine. A new Pokéball rose from inside it, with a lightning bolt sticker on it. "Your father sent you this Pokémon to be your starter."

"He did? What is it? What is it?" The ball opened to show a small yellow mouse with a lightning bolt-shaped tail.

"Pika!" The mouse raised a hand in greeting.

"It's a Pikachu. It's so cute." Ash roughly grabbed the mouse and rubbed his cheek against its.

"Ash I wouldn't do that if I were you." The professor warned. "A Pikachu stores its electricity in the sacks on its cheeks and if they're disturbed the results can be…" The Pikachu let out a Thundershock that hit both humans in the room, sending them to the floor. "Shocking, isn't it?"

"Really?"

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

"Well Pikachu." Half an hour later the boy and his Pokémon were at the entrance to Viridian Forest, looking determinately into the distance. "Onwards to Viridian city, and to being a Pokémon Master!"

"Pika!" The small mouse was as hyped as his new trainer.

"Good, then I'm not too late." Naruto walked up to the child. More than ten years had passed since he appeared in this worlds, and it showed. He was dressed in simple travelling pants and boots, with a button-up shirt and leather vest over it. His hands were in his pockets and a Raichu was clinging to his left shoulder, mirroring the boy. His hair was still as long, tied in a ponytail, and he'd grown a goatee.

"Dad!" Ash yelled and glomped the man.

"Hey kid. Sorry I couldn't make it earlier. I see you got the Pikachu I sent." Naruto rubbed the smaller mouse on the head. "He's actually this one's son." Naruto motioned to Pokémon on his shoulder, who was looking at the small mouse with a mixture of pride and expectation. "You take care of my son now." He tapped his son's Pikachu on the nose, and his tapped Ash with his tail. "And the same goes to you, kid."

"You got it! Together, there's nothing that cat stop us!"

"Pika-pika!"

"Good to hear. You have everything?"

"Yeah."

"Spare Pokéballs? Some money?"

"Yes, all that."

"… Extra underwear."

"DAD!" Ash yelled, starting to walk down the road. "Honestly, like I don't get enough of that from mom." Naruto just laughed and waved again, before turning to Pallet town and his wife.

There was a time-skip there. I don't know if you noticed. It wasn't too subtle, was it?
