I don't own Pokemon or Sherlock.

L-L

It had only been two months since Sherlock died.

John, of course, had a hard time coming to terms with it — still does — Sherlock was the closest friend that he had (maybe even more than that) but he kept living as best as he could, he went to work, and helped Lestrade with the occasional case, but there wasn't much he could do.

At first, he'd thought about leaving 221B and getting a flat without so, many memories, but he couldn't. Not now. He did worry about paying Sherlock's half of the rent, but it seemed to be paid without him doing anything, which was probably Mycroft's doing.

Today was just not her day like any other, without Sherlock, he had just gotten home from work and was sitting in his chair, nothing to do, and nobody to talk to, as usual.

He was just getting ready to go to bed and at least try to sleep for the rest of the day, but before he could there was a loud sound, like an explosion, that left his ears ringing. And suddenly there was a bright flashing light, which blinded him. Surprised, he stumbled back, tripping over the coffee table, landing on the floor with a loud 'Thump!'.

"...mmngh…"

John groaned, sitting up in his bed, wiping his eyes 'another nightmare? That one was a bit different…(It wasn't about Sherlock.)' He yawned loudly, putting a hand over his mouth, and pushing himself out of bed to get ready for work, eyes still too closed to see what was around him. Rubbing his eyes once more, he finally opened them, looking down.

"...huh?"

That wasn't his floor.

His eyes grew wide, and his head snapped up, looking around the room, he seemed closer to the floor, and this definitely was not 221B.

"What the…" John sucked in a breath 'What happened did Mycroft kidnap me in my sleep or something? Why do I feel shorter?'

He looked around, hoping to find a mirror, but there was none to be found. In the room, there was a computer, a television with some kind of game system hooked to it, a dresser, and a large bookcase. And, of course, the bed he just rose from.

He walked to the dresser, opening the cabinets, which were completely filled with clothing. One was full of jumpers that looked like his, but we're smaller, maybe for a pre-teen. The bookcase was full of books about something called 'Pokemon', opening one, he read the first paragraph;

'Pokemon are exotic creatures with abilities no other creature possesses. These creatures, though much more powerful than us, are easily domesticated, and live beside humans as pets. We use them in battles and fight for our entertainment, but there is still so much we do not know, these are my studies. During my time as a Pokemon trainer and researcher…'

John made a puzzled look, wondering exactly what these 'Pokemon' were, closing the book, he shoved it into his jacket pocket. He must not have taken the jacket off when he fell asleep, because he was still wearing it when he woke up. He walked over to the computer and turned it on. A list of options came up.

Item storage-

Withdraw Item

Potion

Would you like to withdraw this item?

Yes

A spray bottle appeared out of nowhere next to the computer, slightly startled he blinked, then picked up the bottle, it had a description on the back;

Potion

'A spray type medicine for wounds. It restores the HP of one Pokemon by just 20 points.'

'HP, points? It sounds like a video game.'John thought, furrow in his eyebrow. He shoved the Potion in his jacket with the book and walked out of the room, and down a set of stairs.

Once he got to the bottom floor, he looked around, it seemed pretty empty, and there was a bag and some shoes next to the door. He took the bag and looked through its contents, just some food and a few sets of clothing. He looked around the house again, noticing a door. He walked over, and opened it, walking into a bathroom.

He instantly took his chance to look in the mirror and almost regretted his choice.

He looked more than a decade younger than he was just the day before.

Hi! This is my first actual Sherlock fanfic, and crossover, so if you have any tips, that would be nice :) and the more concerning part is John's Pokemon team, this is fire red so the team will only be based around Kanto region Pokemon.

(Kinda counting on you guys for team ideas(other than the starter, or one or two other Pokemon unless there are more comments, so that the team isn't just my idea, and he will definitely have a Growlithe, of course)
