A higher, well different realm...

"What are you doing?" One Celestial Pokemon asked another one.

"Peeping at another Universe. This one has almost every power you can think of but no Pokemon."

"Sounds like a control Universe." The first Celestial said. "What would humans do with the power our children possess. How is it?"

"Like Team Rocket was in charge of the making the rules for some of it." The second Celestial said as they uncrossed their eyes. "Not all of the population can have an ability. It's kind of sad really."

"What are you planning?" The first Celestial asked as the other one started behaving a little guiltily.

"Nothing now." The other said.

"So what did you do?" The first one asked with a sigh.

"One teeny tiny little change on one teeny tiny baby human." The other said. "See..."

"You turned a baby into an off-color Ditto?"

"No! That's just the transition for it! He's just a baby after all. He'll start with Ten Pokemon to transform into when he comes of the age most go on their Pokemon Journeys.

"So on his tenth birthday he'll be able to turn into 10 Pokemon to start with? Any legendaries?" The first one asked, curiosity getting the better of it.

"No. That would be overstepping just a bit more than I'm comfortable with." The second one said.

"You're an odd one Mew-Three." The first Celestial said.

"Thanks!" The not quite sane hybrid of Mew-Two and Ash Ketchum said a laugh.

Another Earth...

10 Years later...

"Happy Birthday baby." Inko Midoriya said as she placed the small cake in front of son with 10 candles on it. "Be sure to make a wish."

Izuku nodded before making the same wish he'd made the past couple of years as he blew out the candles.

"Machop?" Izuku said as he felt weird for a second. "Machop!"

"Oh my!" Inko said with a hint of disbelief in her voice. "Honey is that you?"

Izuku looked at his mother before nodding. "Ma- Yes. Talking is weird like this." He said with a look of severe concentration on his new face. "I've got a Quirk! Machop!"

"Oh, we need to get you seen kiddo." Inko said as she hugged her smaller and seemingly much stronger son.

"Cake!" Izuku said while pointing at his birthday cake.

"But first cake!" Inko said as she fought back some tears.

A few weeks later...

"Deku!" Katsuki Bakugo shouted at his one time friend "My mom heard you finally got a quirk." He said with a feral grin as he let off a small explosion in his hand. "Show me."

Izuku sighed and weighed his options.

"Fine." Izuku said as he took off his backpack. He concentrated for a moment then transformed.

"What the hell is that?!" Bakugo said as he began laughing at the transformed preteen.

"Puff." Izuku muttered as he pulled out a microphone from somewhere. "Jigglypuff." He said just before he began singing.

Later that day...

"Bakugo! Detention for that offensive language on your face!" The teacher said.

"What?" Bakugo said before realizing what everyone had been too scared to tell him. "Deku!"

The UA exams...

"Are you ready?" Present Mic screamed. "Go!"

"Pika." Izuku said after transforming and running into the city with insane speed.

The nearest robot was quickly lit up with a powerful bolt of electricity and "Chu!" echoed around the faux city-scape.

The teacher's box...

"Is that a relative of yours boss?" One teacher asked the principal.

"Not that I'm aware of." Nezu said with a hint of a frown on his face. "Hmmm."

This was going to be a strange year.

TBC...

It's like Ben 10, but with pokemon! This one is free for adoption.
