ADVENTURE IN KANTO
Adventure Series

Summary: Aria and Ash go on their first journey together to become a Pokemon Master! But what will happen on their journey? New friends, rivals, meeting Pokemon that they never heard of before in Kanto? What will happen to them when they met legendary Pokemon on their journey? [Book 1 of Adventure Series]

Disclaimers: I do not own Pokemon! I only own any OC characters like Aria or anyone else appearing that I have created. Pokemon belongs to Nintendo and I have claims to owning it!

Preface: You have no idea how long I've been wanting to do this series! Should I start from the beginning where I started to think about this? Okay, let's start from when I got the idea of Aria joining in on the Pokemon anime series. It was all the way back in 2014 in September. I started to wonder when I should start an entire Pokemon series fanfic. Then, I decided to play one of the old games, Soul Silver to get something from it, which lead to me playing X and Y. As I played it, I then went towards the anime series and got an idea from Ash.

When I first took a deeper look at Ash's character and personality, I decided to create a character related to him. Which lead to the creation of Aria Ketchum. She was meant to be like Ash's other half, basically the more organized and creative person. She's more advanced in smarts compared to Ash, so I made her a little more older than him so that it could fit better.

As I created Aria, I started to wonder what I should with her. Then after a lot of thinking through, I decided to put her in the anime. Which lead to it become the Adventure Series. For some reason, I decided to start it off in the Hoenn Region, but then after some time of thinking, I decided to start the beginning on their journey in Kanto, and while I'm working on those two, I'm also working on Unova. I plan to be working on side stories such as Adventure in Aria, which I am currently doing which I probably won't update for a while. But I do plan to have short stories of Aria's alternate universe adventure!

Now that I finally explained it, which appeared very short for me for some reason, I hope you guys enjoy the beginning of this story. Let me know if there's anything that you want to know about the series, the characters, or what I plan to do on the future for this story!

Episode 1: Part 1
Our Pokemon Journey Together!

"Professor Oak, do you know what day it is today?" A young girl asked.

"Ah yes, it's when your brother receives his first Pokemon." The older man said, clapping his hands together. "But you know you really didn't have to come all the way just to find out what Pokemon he will have, Aria. Don't you have a gym battle to do?"

The girl, Aria, shook her head. "No! That's not why! He's a beginning trainer, he'll need help along the way! It's no big deal, really!"

Aria had long black hair, and wore a black and white plaid shirt and short jeans that stopped at her knees. She had a belt around her waist that had two poke balls there, probably the Pokemon she had already caught when she started her journey only a week ago. However, she decided to wait for her brother until he was ready to receive his first Pokemon.

The professor smiles and nods his head. He always knew Aria wouldn't leave Ash behind, but she got a bit of a head start to prepare herself for the battle ahead. She has been training for the week that she had started as a Pokemon Trainer, but she wouldn't go and battle a gym without her younger brother. She was a four years older than him, but that didn't matter to her, but it did to her brother since she was like their mother in a way.

"Speaking about Ash, where is he? Shouldn't he be here by now?" She asked.

Oak shrugs. "I don't know, didn't he said he was going to come here earlier?"

"Yes, but I wonder...he probably overslept." Aria sighs, placing her hand on her face. "That's my young brother, he's gonna have to realize that he going to have to wake up earlier for things like this."

"Spearow!"

A small bird Pokemon flew through the window and sat on Aria's shoulder. It carried a small letter on it's foot. "Oh good, mom did write back. Thanks Spearow."

She takes it off the small letter and opens it up.

"She says that he overslept and is on his way right now." She reads from it, sighing in the end. "Ash, I swear—"

"Hey grandfather, I'm here."

They turned around and noticed Ash's rival walking into the lab.

"Oh Gary there you are." Oak greeted. "Are you ready to receive your first Pokemon?"

"Of course." He replied.

Gary glances at Aria and greets her with a smile. "How's it going?"

"Besides waiting for Ash to get here, I'd say I'm doing fine." She said, exchanging a handshake with him. "So, you all set for your journey?"

"Of course. And who knows, maybe we'll battle some time." He said, taking his hand back.

"Only time will tell." She mumbled as he walked by her. Professor Oak guided him into the lab where he would get his first Pokemon from. As that was happening, Aria heard talking from outside of the building and looked out the window to see a crowd outside. Her eyes widen in shock.

"Jeez Gary, since when did you have a fan club?" She joked to herself. Suddenly, she noticed someone running on the trail and was heading towards the crowd of people.

Aria raised a brow in surprise and shock. "Ash?"

She noticed something different about him, and that he was running all the way there in his pajamas. No one seem to laugh at him because they were only waiting for Gary to show his Pokemon to them.

Aria didn't laugh at Ash because she was too nice to actually do such a thing. She was a very kind person who doesn't like to see people going through tough problems in their life.

"Spearow!" Said the Pokemon that rested on her shoulder as it saw what Ash was wearing.

"Of course, he forgets to change his clothes." Aria sighed. "That's my brother for ya."

After some time of waiting for Ash to get going, Aria watched as Gary headed off with his cheerleaders following him. She gets a sweat drop down her forehead and chuckled awkwardly. She then spots her mother in with the small crowd and noticed that it was completely different from what Gary had. She shrugged her shoulders, putting her hands behind her head. She looked back at the building as the door opened.

"So Ash, which Pokemon did you get?" Aria asked, once he walked outside with the professor. She looked down and noticed the small Pokemon beside him.

"Isn't that the Pikachu you were telling me about professor?" She looks at the professor.

"Yes, but this was the only Pokemon left for Ash to choose." He said.

"Oh, well at least you have a Pokemon, right Ash?"

"Right."

Aria looked down at the people below and noticed that they weren't as crazy as the ones that Gary had with him. When they reached the bottom step they noticed their mother standing by waiting for them, holding a green backpack in her hands.

"I'm so proud of you Ash." She said.

"Aw, thanks mom." He thanked, smiling slightly.

She hands him the bag and he opens it to see what's inside.

"It's filled with everything you'll need on your journey." She said, looking over at Aria. "So you're planning on go with him Aria? How sweet!"

Aria blushes slightly, rubbing the back of her head. "Thanks mom."

"Is this the Pokemon you got?" She asked, looking down at the Pikachu standing next to Ash. "I thought all Pokemon stayed inside of their Poke Balls?" Their mother questioned.

"Oh right." Ash held out Pikachu's Poke Ball. "Return Pikachu."

He tossed the Poke Ball at Pikachu but it only bounced it back with its tail, landing back in Ash's hand.

"What?" He was so confused and did it again, but Pikachu only sent it back.

"Seems like Pikachu doesn't like to be inside of a Poke Ball." Aria commented.

"Well, it doesn't matter, with Pikachu at my side I'll become a Pokemon Master." He said, picking up the electric mouse.

Before Ash could say anything, Pikachu shocked him and it soon did to everyone else, except for the Professor and Aria, who were taking cover.

"Man, that Pikachu sure has some power." Aria pointed out.

"If you have any rubber gloves use them! Electricity has no effect on them!" The professor told the boy.

Once Pikachu stopped, they all fell to the ground, all paralyzed from the electric shock.

"Hehe...well, this is just a great start to a journey." Aria got a sweat drop down her face as she laughed awkwardly.

Aria walked with her eyes shut, listening to the sounds of her own footsteps. That was ruined when she heard something being dragged. She stopped walking and opening her eyes.

Ash was wearing the rubber gloves and pulling Pikachu with a rope. Pikachu clearly was not happy with what he was doing and didn't even what to do anywhere. She frowned, standing in front of her brother to prevent him from going anywhere.

"Ash, I really don't think you need to do that." She spoke after some time, putting her hands on her hips.

Ash sighs and looks at his older sister. "What am I suppose to do? Pikachu doesn't like me." He whined.

"That's because Pikachu doesn't know you well. If you learn more about Pikachu the more it will trust you. Besides, it took me some time for Bulbsaur and I to like each other."

Except Bulbsaur doesn't hurt me unlike Pikachu. She thought.

Ash looks at Pikachu and then back at Aria.

"Okay."

He unties the rope off of Pikachu and takes off the gloves.

"Just dragging Pikachu along won't make it happier, it's only making it dislike you more." She added.

"Pika." It said, agreeing with her.

"See?"

"Okay, I get it." He confirmed.

"You sure?" Aria asked carefully.

"I'm sure."

Ash kneels down next to Pikachu and held out his hand, but Pikachu only looked away.

"Don't worry Ash, Pikachu will get use to you." Aria assured. "It just takes time after all."

Ash sighs, looking at his older sister. "I hope you're right."

"I'm always right. I'm you're sister." She said. Ash grumbled.

"No, the last time you said that you fell into a hole." He pointed out.

Aria tensed, waving her hands. "You get what I mean! Now, let's get going while you two start to like each other, okay!?"

Ash smirked, nodding his head. Pikachu yawned, not caring for what's going on.

This was only the start for the two sibling trainers in the Kanto region.

Yeah, this is just the beginning. It's not going to go through every Pokemon episode but I will go through some of the important ones. Oh, and Aria is only 4 years older than Ash since he is 10 in this and Aria is 14. If you noticed something different about Gary, is that he is friends with Aria, but sees her as a rival like Ash. He's not mean to her like how he is Ash, but the two of them are very understanding towards each the way, if your new to the story the other story 'Adventure in Hoenn' is the other story that involves both Ash and Aria going to Hoenn and having a journey there.
