A/n: Hey! This is a story I've been thinking about for a while. I don't think anyone's done it before, but if they have: oops.
I'm planning on updating once a week, rather than the once a day then nothing for a month schedule for my other stories...

Days before the fateful events at the Potter household, a man arrived in another universe. He had been planning the next events for years, and reminded himself of the fact as he approached the hiding place of the most feared man in the country.

He entered the house, residence to one Lord Voldemort, known more commonly as he who shall not be named, or you-know-who. The man walked through the halls, trying to find the right door. He had arranged previously to meet with the man, knowing that turning up announced would get him killed in a flash of green, just like the rest of his victims.

"Give me one reason why I shouldn't just kill you now."

He didn't know what exactly he'd been expecting from his first visit with the Dark Lord, but it certainly hadn't been this. 'This' being a strange stick to the face and a death threat. A gun, some proper form of weaponry perhaps, but a stick? 'Then again,' he reminded himself, 'These are magicians I'm dealing with.'

Nonetheless, he'd come here for a reason, and there was (literally) no turning back now.

"I know someone."

The cryptic response, served with a smirk, did nothing to quell Voldemort's anger. Voldemort raised his wand further and pressed it directly against the man's heart, but he paid it no mind. The annoying confidence didn't leave him as he continued his short explanation.

"Someone who's immortal."

This got Voldemort's attention. He lowered his wand with a slight reluctance, eyeing the person in front of him with a mix of caution and curiosity,

"I'm listening."

One universe across, Pokémon Master in the making Ash Ketchum was enjoying his travels through the Unova region, journeying with his two companions Iris and Cilan. They were currently travelling around a few islands, named the Decalore Islands, between Kanto and Unova alongside a reporter from the Kalos region named Alexa. Alexa wasn't there at the moment, having left that morning to get some supplies.

Well, he had been enjoying his travels. That was, until he'd had a run in with a couple of legendary pokemon. Nothing big, just the rulers of time and space. And Arceus.

Needless to say, it had been a strange day so far. And it was about to get stranger.

"What's going on?" Iris yelled, barely heard over the primal screeching of Dialga and Palkia, who seemed to be trying to communicate with the trio.

"No idea!" Ash yelled enthusiastically. He waved wildly at the pokemon, failing to catch their attention.

"Do you think... they've realised that we don't understand them yet?" Cilan was getting over the shock of seeing a legendary rather quickly now that it'd happened several times before.

"Probably not," Ash confirmed the suspicions of the other two, "But I don't see why Arceus isn't talking! We can actually understand him!"

Neither Iris nor Cilan questioned Ash's knowledge on the god pokemon, by now used to the way strange things followed him. They both looked around for any other people in the field, but apparently all humans and pokemon had disappeared as the legendaries arrived.

"Yes, they should stop now, shouldn't they?" The voice of Arceus stopped the space-time dragons in their tracks, leaving them silently glaring at their superior. "That's better. Anyway, hello again Ash, Pikachu."

"Hey Arceus!" Ash shouted happily, accompanied by a "Pika chaaa!" from his partner pokemon. "What are you doing here?"

"I am here." The god pokemon spoke with a dramatic air, as was expected of the legendaries, "For you."

At this, Ash pointed at himself with confusion. By his sides, Iris, Cilan and Pikachu nodded in understanding. It was another 'go save the world, o chosen one' deal. "Why me?" He asked.

The question made Arceus shift uncomfortably. "Well, actually... you've become our go-to guy for dealing with evil plots, so by now we just figured you'd just go along with our plan..."

"Oh, okay!" Ash was unfazed by the confession that he was essentially a slave to the legendaries, "What do you need this time?"

"Yes, I'd better explain that now... I'm sending you all to Hogwarts!" Arceus regained his regal attitude.

"Hogwash?" Cilan asked, "What's that?"

"It's Hogwarts! Anyway, it's a magic school somewhere in Scotland. I'm not sure of the details myself, really. I just know that you need to go there." Arceus explained, gaining only blank looks in return.

"A school? Why?" Iris was, unlike her friends, not too excited at the prospect of getting an education.

"A school teaching you how to use magic," Arceus reminded them, "It'll be fun! Besides, I'm not sure you can even do magic... Mew never tells me these things..."

"We'll do it!" Ash yelled, not one for forethought or hesitation.

Cilan, being as he was, more inclined towards actually stopping to think things through every once in a while, was more reluctant to accept. "And how long exactly will we be at this 'Hogwash'?"

"Not long, not long..." Arceus reassured, "Only about seven years or so..."

"Seven years?!" Iris exploded, startling everyone. "I can't go to school for seven years! Besides, won't people miss us? What about participating in the leagues and stuff?" She directed the last question more towards Ash than Arceus.

This got Ash thinking. "Yeah, I don't wanna miss that! Sorry, looks like we can't go!"

"No!" Arceus yelled, "No. It's okay! Mew said something about this. 'Return them to where they were when they left off, they won't miss anything.' Yeah, that was it!"

"Hmm." Cilan was still unconvinced. "Won't that make us all seven years older? That's gonna be suspicious no matter how you look at it!"

This one Arceus had an immediate response to. "Oh, please," He scoffed, "I'm god. I can just de-age you when you get back. It'll be fine!"

Cilan gave a frown, still sceptical. He was unable to voice his concerns however, as Ash made another enthusiastic agreement and Arceus took it as the final decision.

"Right," The previously mentioned god spoke with finality, "I'll be on my way now, as will you. See you in seven years! Or, I suppose, a few minutes..."

Ash and Pikachu waved him off merrily as Arceus teleported away, leaving no more room for argument from Iris and Cilan, who stood gaping beside Ash.

"But..." Iris said weakly, as Palkia and Dialga readied some kind of attack. She never got to finish her complaint, as the attacks finished charging and the trio were zapped away, pokemon in tow.

Over in the Hall of Origin, Arceus watched the humans on their journey across universes. "Come to think of it," He realised aloud, "I never did tell them that Hogwarts was in another universe, did I? Ah well, I'm sure they'll figure it out eventually..."

So, how was it? Reviews and pointing out errors would be appreciated!
