Adventures Across Sinnoh

Chapter 1

Lake Verity

"Diamond!" Pearl screamed at the top of his lungs up at the second floor of his best friend's house. "Get your slow, Slakoth butt down here! We're gonna be late!"

Diamond stuck his head out of his window, hair a mess and food all over his cheeks and yelled "I'll be down in a minute!"

"A second more and I'll fine you one million Pokédollars for being late!"

Diamond hurried to his bathroom and freshened up, wiping the food off of his face and trying to put his pants on head first. He practically tripped down the stairs and crawled to the door, barely making it outside alive.

"Did I make it?!" Diamond asked eagerly as he finished putting on his blue jacket and red hat.

"Nah, you were two seconds over a minute. That means you owe me three million now."

Diamond jumped back. "What?! How is that possible?"

"Interest rates went up." Pearl snickered as he grabbed Diamond's arm and began running, tugging him down the street behind him like a mother and her little child. "Come on, we're gonna run out of time!"

Diamond pulled back and broke his arm free of Pearl's grip. "But the sun is barely even up! We aren't supposed to be in Sandgem Town to meet Professor Rowan until nine!"

"Yeesh, don't you ever get the big picture? We're not going to see Professor Rowan right now. See, get this. I bet if we catch that mystical lake Pokémon that everyone's been blabbing about, he'll be so impressed that he'll have to give us more Pokémon!"

"That's a great idea! - Except for the fact that we don't have any Pokémon!" Diamond pouted. Suddenly, he found himself being forced to take a Poké Ball from Pearl. He looked up and saw a devilish grin on his best friend's face and that could only mean one thing: he had an idea- a very bad idea.

"That's why we're gonna go catch some ourselves, and then catch the legendary Pokémon!" Pearl chuckled evilly.

"This isn't going to go over well…" Diamond thought to himself as they began running through the quiet, morning streets of Twinleaf Town.

After a few long minutes of running, they reached the Verity Lakefront and stopped for a breather.

"Oh by the name of Arceus, I need to lay off the bon-bons…" Diamond said as he fell back against a tree, desperately trying to breathe.

Pearl bent over with his hands on his knees, looking up and laughing at Diamond's pitiful state. "Wow, you're pretty pathetic!" he said jokingly.

Diamond stood up and flipped Pearl the bird as he started walking towards the lake with Pearl behind him.

"I hope I catch a strong Pokémon…" Pearl said to himself.

They reached a clearing and stumbled upon a large and beautiful lake that looked like a bright orange from the morning sun. Magikarp and Goldeen jumped up and down in the lake without a care in the world, while wild Pokémon sat off in the distance relaxing.

There was a man, however. He stood on the lake's edge and stared off into the distance, seemingly lost in thought. He was tall and skinny with awkwardly spiky blue hair and pale white skin.

"This world is so awful and puny…" he said to himself. "To think that the human mind and Pokémon potential is enslaved on this heap of slab and rock."

Pearl nudged Diamond on the arm and pointed at the man. "Hey Diamond, get a load of this guy…"

Suddenly, the man swiftly turned around and began walking towards the boys.

"Excuse me, please let me pass" he requested quite impolitely as he didn't even wait for them to move before he barged right through them, nearly knocking Pearl over. Pearl shot up and turned around, ready to charge at the man but Diamond quickly got in the way and stopped him.

"Hey, c'mon, ki ka." Diamond patted Pearl on the shoulders and smiled. Pearl calmed down and took a few deep breaths.

"All right, let's go get us some wild Pokémon!" Pearl said as they both turned around and stood in front of the tall grass. "I'll give us a countdown. Five, four three- bah! Who's got time to count?! Let's go!" Pearl and Diamond made a break for it.

"Stop!" a booming voice thundered from behind them. The hairs on the back of the boys' necks stood up and they slowly turned their heads around to meet the eyes of a cross, old man. "What in the world do you two ruffians think you are doing?! Do you know how reckless it is to just charge into the tall grass without Pokémon?!"

"Uh-oh… Isn't that Professor Rowan?" Diamond said as he turned to Pearl. "What do we do?"

"Be cool, I've got this." Pearl waltzed up to the man like he owned the lake and flashed him a cheesy smile. "You see, old timer-"

"The nerve…" the old man said to himself.

"We actually do have our own Pokémon! But you see, we were doing a little jog here from Twinleaf Town and we went through a little forest thingy and got separated. We heard their cries from the tall grass and just decided to go and get them! Isn't that right, Diamond?" Pearl turned to see if his friend was on the same page as he was. Diamond quickly nodded in agreement.

Professor Rowan scratched the stubble on his chin and smiled. "Ah, well that is completely understandable. What are their names?"

"Their what?" Pearl nervously stammered.

"Their names- what are they?"

"Oh! Umm… Diamond," Pearl turned over to him again and pulled him next to him. "Go ahead and tell this nice man the names of our Pokémon!"

Diamond panicked. "Oh, umm… Their names are uhhh… Poop-a-doop and Sarah Jessica Parker."

Pearl slapped his forehead and groaned. "Wow, you're really bad at this; there aren't even any Ponyta around here!"

Professor Rowan chuckled to himself. "Well, go on then!"

"What?"

"Wait, what?"

"Go on and find your Pokémon, I'll be waiting right here with my assistant, Platinum. We'll make sure nothing bad happens to you guys while you try to find them." Professor Rowan smiled and called a pretty girl over to his side. She was about their height and looked to be around their age too. Her outfit was comprised of a high-class, fashionable pink jacket with a pair of white designer shoes and white stockings to complete her ensemble. If anything, she seemed too wealthy to be an assistant.

Pearl started walking towards the tall grass when he looked back and saw Diamond staring at the girl. He quickly rushed back and grabbed his arm, pulling him along. "Come on, Diamond!"

"So pretty…" he said as drool fell from his mouth, staring at Professor Rowan's assistant.

The second Diamond and Pearl set foot into the tall grass, two wild Starlys flew up and started angrily flapping gusts of wind at them.

"Ah!" they both screamed as they were blown over by the amazing force of the wind.

"Where are your Pokémon?" Professor Rowan asked them sharply. "They should have heard your screams by now!"

A Starly began pecking at Pearl's head and he tried to shoo it away. "Ack! We lied, we don't have any Pokémon! We were supposed to come and see you today!"

"Yeah, we just thought that if we could catch this mystical lake Pokémon, you'd like us more and give us more Pokémon!" Diamond yelled as he also tried to shoo away the wild Starlys.

"So you two are Diamond and Pearl… Platinum, get in there and help them at once!" Professor Rowan commanded.

"Yes, sir!" She charged into the fray and took a Poké Ball off of her belt and threw it. "Go, Piplup!"
