Niku's appearance:
A/n: Nevermind the ball in hand the glasses and hood stay. For the bottom it doesn't matter to me what you think. I couldn't find a good bottom half. And he is 18 right now.
Major Timeskip
One year has passed after the Unova Region. And Niku has been visiting other regions for a while now. Right now he resides in a hidden mansion on the island relaxing on a beach chair and reading a book with Eevee laying on his lap while his pokemon are training. Niku has trained his pokemon for a long time and they know the routine to train themselves without needing to be told what to do. A few seconds passed and Niku had a sense of something watching.
(Here is the mansion)
Niku: Hmm..... Well what do you know.
Eevee: Vee?
Niku: It would appear we have a visitor watching over us.
Niku made a side glance up in the trees to see a certain deity staring down at him curious. When suddenly he hears a stomach growling and sees it was Eevee who was embarresd and chuckles.
Niku: Dont worry Eevee. I will make you your favorite meal.
Eevee: Vui, Vui!
Niku: Sure you just have wait a while for me to make it ok?
Eevee: Eeee!
As Niku was about to head back inside, he heard voices on the same island he's on but sounded like someone is in trouble with some bad people.
Niku: Eevee, lets handle this first. Then I'll make your favorite meal is that a deal?
Eevee: Eevee Eevee!!
Niku: Alright let's go! I have someone that needs exercise. Everyone just keep doing what your doing ok?
Niku's Pokemon: (Roar)
Scene Change
At the place where the commotion is, Ash and his new friends from the Pokemon School are against an evil organization from the Kanto Region known as Team Rocket who are responsible for taking there Ride Pokemon.
Lana: How cruel!
Mallow: What do you guys want?!
Jessie: If you ask us "What do you guys want?!"
James: Let us tell you what our names are.
Jessie: A flower's face and a willow's waist, makes the moon mortified and flowers wilt, a lone flower of evil blooming in this transitory world, Jessie!
James: An eye for opportunities, valiant and heroic in bearing, an apostle of evil retaliating against the agonizing world, James!
Meowth: Sharing the same fate, splitting responsibility, a star of evil whose shines even on close friends, Meowth!
Jessie and James: Team Rocket is on the scene!
Meowth: Meowth, that's right!
Wobbuffet: Wobbuffet
Meowth: Listen up, bratties!
James: These Lapras will be instituted into the Team Rocket Organization!
Without any warning, a blur of electricity slashed through the net, cutting them free, surprising everyone.
Team Rocket: What the?!
Sophocles: What just happened?! And what was that?!
The electricity formed a circle and grew bigger and exploded forming a Pokemon which everyone was surprised about the sight of the creature.
Miraidon: Miraaa!!
Sophocles: Incredible!
Ash: No way!
Lillie: What a fascinating Pokemon! I've never seen one like that!
Rotom Dex: Does not compute. Does note compute. It's not one I can recognize.
Lana: How did that Pokemon get here?!
Mallow: Does it belong to somebody?!
??: Well Well. So you guys are the stooges I heard about it Kanto working for Team Rocket. To think you would come here and cause more trouble like you did in the other regions. How low can you go. So pathetic.
Everyone looked back to see a kid with a hood on and an Eevee on his shoulder standing on top of rock.
Kiawe: Whose that guy?
Team Rocket looked at man in anger.
Meowth: Hey!
Jessie: Give them back!
James: Those Pokemon belong to our organization!
Niku: Shut up! Miraidon Thunder, Eevee, Copycat!
( The move it used was Electric Drift if you were wondering. Even though that was the signature I wouldn't waste it to finish on them )
Miraidon and Eevee: Donn!/Eevee!
Miraidon charged up electricty and Eevee did as well and shot a huge blast electric energy. With the two moves combined it blasted Team Rocket away when all of sudden a Bewear ran across on water, catching them and escaping with them resisting not wanting to leave with it.
Niku:... Well.. That was awkward..
Rotom: A Bewear that can run on water? Data: Updated.
After the defeat of Team Rocket, Niku walked over to join the others.
Niku: Well that was pitiful for them. Are you guys alright?
Mallow: Yeah, we are. Thanks for that!
Lillie: Yeah thank you so much!
Niku: It was nothing. My two friends here did the work.
Ash: Wait is that you Niku?!
Niku heard his name shouted and saw Ash looking at him surprised and amazed.
Ash: You remember me?! It's me Ash! We battled against eachother in the Unova Region at the Junior Cup! You gave me the trophy and disapeared.
Lillie: Wait really?!
Lana: Is that true?!
Kiawe: Not bad.
Niku looked at Ash and narrowed his eyes and widened them.
Niku: Oh now I remember you. Your that Krookodiles trainer aern't you?
Kukui: So you're Niku right? I've heard about you before in Unova from Ash. He said you have Pokemon no one has seen.
Niku looked over and saw Kukui walking up to him, not surprised to see him.
Niku: So you're Kukui huh? The professor of this region.
Sophocles: Professor do you know him?
Kukui: Not personally but Ash mentioned him before. But to think I get to see you in person.
Niku: Same here, I know about you Professor and your school. Gotta say you've got a fine reputation. And I assume you attend this school, Ash?
Ash: That's right.
Niku: So what happened here? Looked like you were in the middle of teaching.
Mallow: Yeah, Lana was teaching about the water Pokemon in the sea.
Niku: Really. She must be a genius about water pokemon.
Lana: Oh thank you Niku!
Niku: I guess that means your all students correct?
Kukui: That's right. How about you come tomorrow and have a look around?
Niku: Are you sure?
Ash: Yeah, you'll like it!
Niku put his hand under his chin in thought.
Niku: I dont see why not. Sure.
Kukui: Great. You wont regret it. I'd like you to meet my students.
Kiawe: Kiawe
Sophocles: I'm Sophocles!
Mallow: I'm Mallow, nice to meet you!
Lillie: I'm Lillie, it's a pleasure.
Lana: Lana. Hope we can be friends.
Ash: Ash is the name. And this is my best bud Pikachu. And this is Rotom Dex.
Niku: Nice to meet you. As you know this is Eevee and the big one here is Miraidon.
Eevee: Ee.
Miraidon: Mirai!
Ash: Wow, I remember Ursuluna but this new one Miraidon makes it more exciting to see you!
Lana: This is really new.
Mallow: Yeah how did you get it?
The students went to Miraidon to have a closer look at it but it growled at the and they flinched.
Kiawe: Woah what wrong?!
Niku: Sorry Miraidon is still getting used to seeing other people. I've only had it for a few years but still fears humans. I'm the only one it trusts.
Kukui: Oh, it must've been through alot.
Niku: You have no idea. Hmmm?
Niku looked behind him and could see a shape of a certain guardian he met and chuckles. The others looked to where he was facing and can see anything.
Ash: Hey what you looking at over there?
Niku: It's nothing I just had a sense of someone nearby. So anyway where is your lab professor?
Kukui: Oh, just follow me and Ash lives there as well.
Elsewere from a far view, the Pokemon from earlier watched him and still continues to follow him.
??: Tapu.
Timeskip ( Kukui's House)
When they left the island, Niku followed Ash to Kukui's residence. When they went inside the style was impressive and decorative.
Niku: Wow, nice digs. This is a great place for you professor.
Kukui: Thank you! So Niku where do you stay?
Niku: Oh I live in an abandoned house I found on the island. It may look old but I made some improvments.
Ash: Oh, I was hoping you'd live here.
Niku: Sorry Ash, but dont worry I'll still come visit the classroom.
Kukui: Oh thats good to hear.
Niku chuckled and heard Pikachu spinning around Eevee who just stands there not making any motion and finds Pikachu annoying. Niku sweatdropped that Eevee still wont want to be friends with other Pokemon but she'll warm up eventually.
Ash: Oh yeah, Niku.
Niku: Hmmm?
Ash: Can we have a battle? I've waited a long time to find you and have a battle again after the tournament but you left immediately.
Niku: Yeah about that... I just had things to do so I couldn't stay longer. And I didn't care about facing Alder. I just wanted to face strong opponents and get the Pokemon you saw that time to see the world. And no we cant battle just yet.
Ash: What?! Come on!! I want to have a chance to defeat you!
Niku:... -_-..Don't push your luck Ash. You just gotta be patient that's all. Oh, it's getting late, Eevee lets go home! I've got a good meal for you to eat!
Eevee: Eevee!!
Niku left out the door and Eevee jumped on his shoulder and turned around.
Niku: Well see you around guys!!
Kukui/ Ash: Bye!!
Niku ran out back to his place unaware the Pokemon followed him again leaving him something at his house.
Second chapter out. Let me know if I make mistakes I'll fix it. Some pictures I couldn't find but found these instead.
