AN: Hi everyone! This is my first ever Pokemon fanfiction which I hope you will enjoy! The story follows the Diamond and Pearl Anime with a 4th companion added to the group of Ash, Dawn and Brock. Some chapters (such as this first one) will be based off real episodes from the show, while others will be completely new content. Their new friend has lost his memory completely, and he joins the group with the hope of rediscovering his past. It will take him a while to discover his own secrets, so don't expect too much to be revealed at once. In this first chapter, he doesn't even know his name. (But don't worry, he'll get a name shortly.) This first chapter will be in third person, from the perspective of Dawn's loveable partner Piplup!

Please enjoy, and of course, I don't own Pokemon.

Piplup was feeling pleased with itself. The group of Ariados had been sent packing when Piplup gave them a dose of its Bide attack. The Blue haired girl it was protecting was very grateful for what Piplup had done. She grabbed the tired Penguin Pokemon and began to walk away from the scene of the battle. After a few moments, they stopped.

"Hey look Piplup, it's Lake Verity." Said the girl.

She wore a white beanie hat with the top half of a pink Pokéball on the front. Her eyes were the colour of a Saphire and a Pink scarf was around her neck. She also wore a black vest which exposed her shoulders, a short pink skirt and pink boots on her feet.

Before anything else could be said, Piplup's stomach growled loudly, causing it to blush. The girl didn't have much food left, but she gave what she had to the hungry Pokémon. They were just about to begin heading back to the lab when they heard a very strange noise.

Piplup looked up, and to its surprise there was something very unusual in the air. Floating about 10 feet above ground, there was some sort of 'hole' in the sky. It was fairly circular, around 10 feet in diameter.

"Woah, what's that? Some sort of Black hole?" The girl exclaimed.

What they saw next shocked them both as Piplup could make out 2 figures being launched out of the hole. They were moving fast so it was difficult to make out the details, but one was clearly a Human while the other was much smaller. Surely a Pokémon?

The pair were sent hurtling through the air. They fell straight into Lake Verity, causing a large splash that drenched Piplup completely. Instinctively, the Penguin Pokémon leaped into the lake, desperate to try and help the mysterious pair. As Piplup dove underwater it saw the 2 of them, sinking towards the bottom of the lake. As Piplup swam towards them it was stunned when they were both enveloped by some sort of underwater mist.

Piplup quickly resurfaced, jumping up and down, frantically waving its flippers up and down.

"Piplup! Lup! Pip! Pip!" It yelled, trying to get the girl's attention.

However, her attention was clearly drawn elsewhere as she was staring at something behind Piplup, her mouth open wide showing the shock on her face. Piplup turned around to see a mysterious figure seemingly taking shape from the mist. It had a small body, with a slightly larger head. It appeared to have 4 long curly Ears as well as 2 long curly Tails.

"Wh-what's going on? Did that figure summon the hole in the sky?" Asked the confused girl. At that moment, the mysterious hole quickly began to shrink, until it was no longer there at all.

Just then, Piplup noticed something. Sprawled out on the grass next to them were 2 unconscious bodies. It was the same 2 that had fallen from the sky! Now that they weren't moving so fast, Piplup could see what they were. The first was a young man, who looked maybe a little older than Piplup's Human friend. He had short black hair, pale skin, a dark green T-shirt, and black shorts and trainers. Piplup immediately noticed an abundance of cuts and bruises along the young man's Arms and Legs. The second was a small blue Pokémon. It had 4 short Legs, a short black tail with a yellow star on the end, and the rear half of its body was black. If Piplup had learned anything from listening to the Professor back at the Lab, that was a Shinx. They both looked exhausted and beaten up. The good thing, though, was that both were breathing heavily, which is far better than not breathing at all!

"Oh dear. They don't look okay. Piplup, we have to help them!" exclaimed the girl.

Panic showed on her face as she and her Penguin friend frantically paced up and down wondering what they could do for at least a minute or so.

Suddenly, they heard a painful groan. It was the Human! Piplup and the girl dashed towards him as he weakly opened his eyes. He was clearly making some effort to say something but didn't have the strength to do so.

"F-f-food. P-p-please." He managed to mutter, just loud enough to be heard. They had none, so Piplup quickly sprinted off into the nearby woods to search for some sort of food, clumsily tripping over every few steps. Cries of "Pip!" "Lup!" and of course "Piplup!" were heard frequently.

"Piplup! Over here quick! There's some fruit in this tree!" It was well out of reach so the girl thought for a moment until an idea came to her. "Piplup use Bubblebeam!" Piplup obeyed her command despite her not yet being its Trainer. It successfully knocked a few Oran Berries down. They ran back over to the Human and the Shinx, who were both now awake but still laid on the floor. The girl fed some berries to the boy while Piplup did the same for Shinx. The pair could barely muster the strength to chew at first, but with each berry they seemed to gain strength.

After they were out of berries, the young man managed to push himself into a sitting position. He glanced over at the girl.

"Th-thank you." He managed the faintest smile.

She blushed slightly. "Oh it was nothing. Piplup did all the work." Piplup also blushed a little.

"My name's Dawn, and this here is Piplup. It's a really brave Pokémon." Piplup's blush intensified.

"What's your name?"

The young man seemed to be thinking for a moment, scratching the back of his head. It looked, at least, as though his strength was returning to him.

He Frowned. "Honestly, I've got no idea. I don't seem to remember anything!"

Dawn looked puzzled. "Nothing? Not even your name?"

The young man responded. "Nope. Nothing at all. Sorry."

"So who's this Pokemon with you?" She gestured towards Shinx.

The young man turned around and for a moment, his eyes lit up.

"That's a Shinx, right?" He asked and both Dawn and Piplup nodded.

"Well, Shinx is my partner. I'm sure of it!" He looked much happier now.

"So if Shinx is your partner, where's its Pokéball?" Dawn questioned.

He felt around his clothing for a pocket containing a Pokéball, only to find he didn't have a single item in his possession.

"I guess I don't have one. But Shinx is my partner. I'm certain about it!" Upon hearing these words Shinx seemed to regain much more of its strength. The Electric type leaped onto its feet and nodded in agreement, a beaming smile on its face.

At last the young man was able to stand up too. He was noticeably taller than Dawn, upon standing it also became more visible that he was rather muscular. He seemed to have the physique of someone who worked out every day.

"So, Dawn and Piplup, how did you find us?" He asked.

Dawn did her best to explain everything. The hole in the sky. Them falling out of it and the mysterious mist that saved them.

The young man looked stunned. "So, let me get this straight. We fell out of the sky, were about to drown and were saved by some sort of magical mist Pokémon?"

Dawn smiled sheepishly. "Well, pretty much, yes."

The young man though for a moment. Under other circumstances he might not have believed her, but somehow he didn't doubt her words one bit.

"In that case, Dawn and Piplup, we owe our lives to you. I will do my best to repay you someday, somehow." Dawn smiled in appreciation of his offer.

After a moment a thought came to Dawn's mind. "So, what are you going to do now?"

A puzzled expression appeared on the young man's face, until he eventually shrugged, smiling sheepishly.

"In that case, why don't you come with us? Soon Piplup will become my partner and we're going on a journey around Sinnoh. My aim is to someday become top Coordinator! Maybe we can find out who you are!"

The young man grinned. "Well it doesn't look like I have any other option does it? I don't know what a subordinator is butI'm sure you'll be a great one so let's do it!"

Dawn sighed. "I said Coordinator. But thanks. And there's no need to worry. We'll find out who you are soon enough I'm sure."

The two young adults grinned and set off towards Professor Rowan's lab so Dawn could officially receive Piplup as her Pokémon. Little did they know this was the start of an epic journey.

Meanwhile, 18-year-old Ash Ketchum was departing a large ferry. An Electric type Mouse was sat upon his Shoulder. He was due to meet up with his long time friend, Brock, in a couple of hours. Their Sinnoh journey was about to get underway. What he didn't notice, though, was the Meowth shaped Hot Air Balloon floating overhead, containing a certain villainous trio he was all too familiar with...

AN: So what do you think? Reviews would be appreciated. Especially constructive criticism. Speech is in bold to make it easier to distinguish from regular text. In the next chapter our new hero will discover a little bit more about himself and Shinx, his name will be revealed, and he and Dawn will encounter Ash and Brock for the first time. It also may or may not include a certain blue haired man, pink haired woman and talking cat-like Pokemon.

Also, he will be catching more Pokemon throughout the story. Some of them will be heavily plot driven. Ash, Dawn and Brock will be catching the same Pokemon as they do in the real show, but they aren't the main focus of the story, so they will be catching their team members in-between chapters.

One last thing. I've always thought the idea of 10-year-olds travelling the world is pretty stupid. So in this story Ash started his journey aged 14 and has been travelling for 4 years. In the Sinnoh region, though, rules are harsher and the minimum age for new Trainers is 17. So here's the official age of our 4 heroes:

Ash - 18

Dawn - 17

Brock - 23

? - 19

Thanks for reading! I will do my best to update this story regularly. Hopefully the next chapter will be out within the next day or 2.
