What if Pokémon existed in Naruto's universe?

Ash, Matt, Brock and Misty were heading to Konoha, a hidden village defended by strong ninjas, to communicate an important piece of news. When they arrived, after traversing forests and hills, the guards on the front doors revised their documentation.

-Everything looks right guys, you can come in – said one of the guards.

The four ninjas continued running towards the hokage when, suddenly, a pair of voices broke the quietness of the village. The ninjas stopped right on their feet and stood alert, wondering if they had been followed.

After a few seconds a blonde guy ran through, with a very frightened face, and seemingly he was running away from a pink-haired girl who had an angry face. The guy hid behind Brock, but the girl discovered him.

-Naruto, come here and apologise! Or I'll give you such a punch that even Tsunade's powers won't be enough to help you recover!

-Sakura-chan… Saying that you seemed to be possessed by the devil when you get angry was just a joke… - said Naruto, smiling wryly and scratching his head.

-The poor guy is right… she sure seems to be a demon… - murmured Brock into Matt's ear.

-Indeed… she only needs the horns… - answered Matt.

-Did you two say something!? – said Sakura, cracking her fingers.

-Nothing! – said the ninjas at the same time, with sweat running down their faces due to anxiety.

A pale guy then appeared with a canvas on his hands with a drawing in it.

-Look Sakura, I drew your real form – said the guy smiling.

It was a gigantic demon with a very big hammer and a stern face.

Sakura gathered a lot of chakra in her fists and prepared to attack.

-Sai, you finished with my patience! – said Sakura while trying to hit the guy with her physical attacks. Sai dodged her attacks swiftly, making his drawings come to life.

While Sakura and Sai fought, Naruto decided to go out from his hiding.

-Did the fat cow go? – said Naruto with a bit of fear in his voice.

The others nodded.

-I don't think I've introduced myself. I'm Naruto from Konoha! And someday I'll become the best hokage this village has ever known!

-You don't seem to be that strong.. – said Ash laughing sarcastically.

-You don't seem strong either… - answered Naruto while smiling back.

They looked in each other's eyes defiantly.

-We're Ash, Matt, Brock and Misty, and we're travelling from the hidden village in Kanto to tell an important piece of new toy your hokage – said Misty.

-What a coincidence, I have a meeting with her today! I'll go with you! – said Naruto.

-You don't imagine how thrilled I am… - said Ash, whining.

-Did you say anything, blackie? – said Naruto slightly annoyed.

-Nothing of your business blondie… - answered Ash.

Then Misty punched them to the floor in her characteristic way, and said:

-Stop behaving like kids! I don't know about Sakura but I sure can transform into a demon… - said Misty smiling maleficently.

Then they all proceeded to the building where the Hokage was.

When they got there a short-haired woman who wore a kimono and that was holding a pig between her hands said:

-I'm sorry guys, Tsunade is very busy right now.

-What? Shizune, this is an emergency! These guys and me have to tell her something very important! – answered Naruto.

-Then tell me and I'll tell her – replied Shizune.

-We've received the order to report to Tsunade herself, Kunoichi – said Misty.

Naruto jumped up on one of the windows and ran towards Tsunade's office. Tsunade, notably angry, punched the table so hard that she sent all the papers that rested on it flying.

-Naruto!

She was so angry that her yells could be heard all over the building. Her helper and the other ninjas appeared to check out if everything was OK.

-Shizune, didn't I ask you to look after the entrance!?

-I'm sorry madam, he started running all of a sudden and I couldn't…

-Naruto, don't think you're gonna escape free, you are going to pick up every sheet of paper that is on the floor! – said Tsunade.

The ninja started to pick up the papers. After a few seconds, Tsunade asked:

- What about you? What brings you here?

-We come from the hidden village of Kanto, and we bring an important message dor you, Hokage.

-Go on, you have my attention – replied Tsunade, leaning on the table.

-Our explorers confirmed that a renegade ninja is approaching. He grabbed control of the three legendary birds, and he has evil intentions… - explained Ash.

-Sasuke… - murmured Naruto.

Tsunade thought for a second about what she'd heard, and then said:

-How do those birds look like?

-They're Pokémon that are very rarely seen by human eye – answered Brock. – Each one of them has powers linked with nature. Articuno is linked with ice, Zapdos with electricity and Moltres with fire.

-They seem to be powerful beings… They can pose a threat to this village… - said a very worried Tsunade.

While she thought out a plan, she invited the guys to spend the night in the village. Naruto, who was still picking up the papers, volunteered to get them to the nearest hostel. When they arrived they realised that the clerk was an acquaintance of Naruto. It was a white-haired man, with all the face covered with the exception of an eye.

-Kakashi-sensei? What are you doing here? – asked Naruto.

-I took the place of a colleague while she is out – answered Kakashi without stopping reading a novel that seemed to have him completely mesmerised. – By the way, who are your new friends?

-We are from the hidden village of Kanto and we come here on official business – said Matt.

-Yeah well… the Hokage asked us to stay here tonight… would you mind listening to us? – said Misty.

Brock, who had been analysing Kakashi's novel all the time, decided to interrupt the conversation.

-That novel… where did you get it?

-This one? – Said Kakashi – It's not for sale yet…

-How lucky you are, I've been waiting for years to have it! Can I read a bit of it please? – sobbed Brock.

-Hey, I also want to read it, I'm a fan of Jiraiya-chan's novels! – said Matt.

Misty then did one of her jutsus, making water chains wrap to Matt, Kakashi and Brock's legs.

-It's not enough… I'm… still… ANGRY! – said Misty, while throwing out a Pokéball. – Gyarados, Hyper Beam!

The beam hit the ninjas unconscious.

-Very well… now where is our room? – asked Ash.

The girl looked at Ash, and suddenly hit him with a punch full of chakra. Ash went right through one of the walls and up in the sky.

-Well, now we can go to sleep – said Misty, after relaxing.

-Misty… aren't you worried about where Ash went? – asked Naruto.

-Don't worry, he always find a way back – answered Misty.

Naruto chose to remain silent, hoping not to be punched by the girl.

Hours later, everybody except Kakashi were sleeping in a room when suddenly they heard some big birds trilling.

They looked up in the sky and they saw a giant shadow flying between the buildings. The ninjas decided to go up in the roof. Once there, they saw how three big birds flew above the village while Konoha's inhabitants ran about, full of fear.

-Look, on top of one of the birds there's… someone – said Misty.

The mysterious shadow gave an order to the bird it was on, and then a powerful flame came out of its mouth and hit the wooden houses, which started a very dangerous fire. The villagers ran away in shock via an escape route organized by the ninjas.

Naruto and the other ninjas who were with him went quickly to the Hokage's building. In the way they found Hinata and Sakura, who were also searching for Tsunade. They decided to go search for her togetherm but the flames were getting bigger and blocked every path.

-Guys, it's time to act – said Misty while holding a Pokéball. – Starshe, I choose you!

-Go on Blastoise! – said Ash.

Starshe and Blastoise combined water attacks to suffocate the fire.

-Dralyx go help them! – said Brock.

-Come on Starhe! Water Gun the flames! – said Matt.

Naruto, Sakura and Hinata were trying to stop the ninja from attacking.

-Hey you, stupid shadow, come down if you dare! – said Naruto, hoping that his dear friend wasn't the one attacking Konoha.

But the closer the fire bird got, the more Naruto's fears came true. The shadow was no other than renegade ninja Sasuke. He stepped down from Moltres with elegance.

-Why does he have so much hatred towards Konoha? – asked Naruto to himself.

-Sasuke-Kun! – said Sakura melancholically. – You came back to stay, don't you?

-Naruto, I came back to pick you up – said Sasuke, ignoring Sakura.

-Why do you think I'll go with you? – answered Naruto.

Without adding a word, Sasuke telephatically ordered the birds to come closer to Naruto.

-Attack… - whispered Sasuke.

The legendary Pokémon shot three powerful beams of ice, electricity and fire, hitting Naruto and Sakura unconscious. Hinata avoided the attack.

-Naruto-kun! He is a humble boy that wants to protect his village and his friends…

Hinata then started assembling chakra in her fists, moulding them in the form of a pair of lions' heads.

-You'll regret attacking Naruto! – said Hinata while running towards Sasuke.

They started a huge physical battle, in which the sharingan and the byakugan fought to discover the weakest points of their rival quickly.

After a few seconds of fight, Hinata succeeded In punching Sasuke in the face, making him hit the floor and creating a crater in the process. But Sasuke got up and counterattacked with a punch that made Sakura faint.

But Sasuke received a kick that sent him up in the sky. It wasTsunade's Lopunny.

-You are not going to destroy my village only because of a whim of yours. Get out right now.

But Sasuke didn't listen, and commanded the birds to attack again. This time they hit Ash, and when Pikachu saw the bad luck his trainer had, he kept on filling water buckets to help suffocate the fire, and said:

-Pika pika…

While Sasuke was fighting Tsunade, Sakura punched him from behind. The boy avoided it, but it was just a distraction. Sasuke was then surprised by Sakura's Medicham, who used Zen Headbutt in Sasuke's stomach.

Sasuke commanded Moltres to use Hurricane and Zapdos to use Zap Cannon to engulf his enemies in a magnetic storm.

-Articuno, pick me up – said Sasuke while carrying the unconscious Naruto.

Then he said:

-Articuno, use Water Pulse!

The attack, combined with the magnetic storm, made all the Pokémon and Trainers faint.

Sasuke was about to leave when Sakura's Espeon used Zap Cannon and surprised him, making him fall from the bird he was on.

Sakura healed the ninjas and asked them to arrest Sasuke and bring Naruto back.

While Sasuke was resting on a tree with Naruto still with him, Misty yelled at him:

-Hey don't you think what you did is not going to have consequences! You can't provoke chaos just for your selfish reasons! – said Misty.

-I'm only claiming what's mine – answered Sasuke.

-The village is not yours; it's of its villagers! – replied Brock.

Suddenly Naruto woke up.

-Hey Sasuke leve me alone! Why are you destroying our village? Did the Orochimaru snake make you hate all of us? You are a traitor and you killed your own master because… - Sasuke interrupted Naruto by giving him a gentle kiss in his lips. Everyone were shocked with what the renegade ninja had just done.

-What are you doing!? What do you want from me!? – asked a blushing and very nervous Naruto.

-Didn't you get it already? You are as innocent as ever…

-You are an idiot… - said Naruto while resting his head on Sasuke's chest.

-You're gonna tell me you didn't like it? – said Sasuke smiling.

-No, of course I didn't! – said Naruto, pushing Sasuke apart.

-Now you are playing the tsundere part? – said Sasuke – OK, let's talk about this at home.

Sasuke made Zapdos come down. He made a reverence towards the ninjas as an apology, took Naruto's hand and they both climbed up Zapdos. The ninjas of the hidden village of Kanto, still in shock, saw how the couple departed on that summer night.
