"It's been sixteen years huh?" a boy with black hair, brown eyes and a hat walking in a forest with a Lucario by his side.

"Ahhrr?" the Lucario look at him confused, the boy shook his head, "Nothing bud just something on my mind hehehe." he look above and smile, 'Sixteen years and its still unbelievable that I reincarnated in the Pokemon world.' his ears perk up as he look ahead.

"We've got company bud." the Lucario grinned and jump in front and its paws start glowing blue. "Rooaar!!" an Ursaring appeared with glowing red eyes.

He was originally from earth a 17 years old student from the Philippines, his name is Leo Perez and he was the only child in the family but he never complained since the thought of having a sibling is annoying.

He love playing volleyball with his friends and he was the captain of the team, he love his life until an accident that caused his death. He together with his friends were leaving the gym late at night, they were on the road when a light flashed behind them.

They curiously turns around and they saw a van heading to them fast and it seems the driver is drunk, he who reacted quick pushed his friends and he was hit by the van hard. He was sent hurling on the street, the driver who notice he hit something stopped the vehicle and open the van.

Leo's friends who witnessed Leo getting hit run after his buddy, when they arrive they saw Leo's bloody unconscious body breathing heavily, they were frozen from shock and broke down and one of Leo's other friend quickly called his parents.

One of the taller boy turns around he saw the driver standing in daze with red face, the taller boy who quickly understood that this man is drunk and the one who hit his friend, he rushed and gave a hard punch knocking the man off his feet.

After Leo's parents arrived with an ambulance they rushed him to the nearby hospital, but before arriving Leo's body collapsed and died. Meanwhile the culprit was beaten up by Leo's enraged friends before the man was arrested.

\--------------------------------------------------

Leo who thought he died suddenly woke up as a baby, he freaked out and frantically look around and was shocked to the core.

There stood a woman but not any woman, it was Delia Ketchum the mother of Ash Ketchum the protagonist of the show Pokemon.

Then after a while he calm down and understand his situation, it was the infamous isekai cliche. He who a former Pokemon fan knows a lot in the Pokemon world, examples are aura and psychic, this two ability are super op.

He tried to develop his aura and psychic power, since he knows how underestimated this powers, he began meditating, Delia was confused by his son sitting-closed eyes, giggle and took many pictures.

It took Leo 3 days to access his aura and a week for his psychic, if you ask Leo what is aura then it would be like ki and magic.

Aura is superior in physical power while psychic is superior in mental power, he circulate his aura around his body so he could be physically powerful.

He practice his psychic and made a mental barrier since he don't want any mind intruder.

He met Daisy when his mother brought him to their neighbors, Daisy would always hold him when she visited them. When he and her mother visited the Oaks he met Gary, he was super cute and will follow him around.

Leo or Ash now didn't do much to gather attention and just behave like a growing baby but smart baby. When he turned seven he ask prof. Oak if he could learn under him, and Oak who knows that Ash is really smart for his age decided to take him.

Gary was different from his canon part and he seems to look up to Ash and always follow him around, and Ash who's amused by the situation made him his little brother, he pat his head every time he do something good. However the adults found this interaction really sweet, Gary follows Ash and Ash pats his head like brothers.

Two years and prof. Oak was amazed, it seems that Ash knows more about pokemon, not about their behavior interactions or names, but about the legends.

\--------------------------------------------

"Ash what do you know about the history of pokemon?" prof. Oak asked while looking at Ash. Ash look at him and grinned mentally, decided to surprise him.

"Umm.... well long ago before everything exist there was an egg, then came an pokemon from that egg was Arceus the Alpha pokemon." Ash said. He looked at the surprised Oak.

"You mean the legend in Sinnoh region?" asked a surprise Oak. How did Ash knows this? There wasn't any information in kanto, he knows this since he met the professor of the region.

Ash ignore his question and continue, "Then comes Palkia, Dialga and Giratina. Palkia the ruler of space, Dialga the ruler of time and Giratina the ruler of distortion wolrd." again Oak look at him surprised, that information about those legend is really obscure, and little knows them.

"Then Necrozma the ruler of ultra space a dimension where the pokemons are much powerful than the pokemons here." he said as he stopped and look at prof. Oak.

"Who is Necrozma?" Oak ask with a suspicious stare. "How do you know these? You're a kid and from what I can tell, it seems like you know more about the history." he look at him waiting.

"Don't ask, but listen." Ash said with a straight face as he glance at the window, "Do you know what's an aura guardian?"

"How do you know that?" ask Oak with a surprised expression. Ash smiled at him, "I'm one of them and a special one."

"The last aura guardian recorded was Sir. Aaron of Cameran castle." prof. Oak eyes widened, Ash is an aura guardian and maybe related to Sir. Aaron.

"Before you assume that I'm related to Sir. Aaron, I'm an aura user not guardian since they are protectors of aura, however me, I'm born special with the ability to manipulate aura." you may ask why Ash is telling his biggest secret, because prof. Oak is good and trustable, in the series Oak knows about Ash is an aura user.

"So, you gonna give me a Pikachu as a starter?" asked Ash with gleeful expression.

"How do you know that!?" Oak look at him with a stunned face.

"Of how I know I traveled to the past to save Celebi? I know alot about something you don't know." Ash said with a grinning expression. Prof. Oak look at him terrified, is he a time traveler?

"No I'm not a time traveler, your face tells everything." Ash smile widened. "You may wonder why I'm telling you these is because you're the only person that can be trusted not even my mom." he said with a serious face.

Oak stood shock and surprised, "Ash... thank you, when I remembered you from the past I was really elated of paying you back." prof. Oak said with a sincere smile and bowed his head. "Also how do you know this?" he ask with an eager smile.

After the entire conversation ended, prof. Oak said that he will support Ash and wouldn't tell anyone about his aura power.

At the age of nine he became the worlds youngest professor after discovering the new fairy type pokemon(more like him taking the credits of others), he created novels from his previous life and edited a few story lines like the story Frozen as a kids story.

It became a hit in the intire kanto region, Gary was almost worshipping him and it weirded Ash out. A lot of people was interested in Ash after it became a hit, but it got more after he released his new story Beauty and the Beast(Instead of characters becoming things, they became pokemons, like the candle man became Litwick and the prince became a Lucario.).

Because of this book he became rich and decided that they need a bigger house and told his mom and agreed.

His growth in power is monstrous.

His aura power skyrocketed, he was able to manipulate to the point of affecting reality. He manage to manipulate matters on a molecular level, he can use aura as a platform, fly, armor, convert aura to elements, physical enhancement and many more.

On his psychic powers he was able to create a mindscape, he had a perfect memory and developed muscle memory. He can teleport anywhere without exhausting his body, he can hear thoughts and read minds even from far away. At his full power he can levitate the entire Eiffel tower, he can sense mind from a mile away.

He now mostly don't use his power and did not practice much after his monstrous growth in power, he was sure that it was enough for him to battle any threat(aside from Arceus, Palkia, Dialga, Giratina and Necrozma.).

A year later his journey of becoming a trainer began, he received a Pikachu from prof. Oak as a starter and a Feebas per Ash's request. When Ash interact with the rodent, it tried to shock him and much to its surprise, it didn't even phase him.

It tried to shock him again when it felt an heavy aura, it's stop and look at Ash terrified, "Ya know I was being nice to you and you decided to attack me." Ash said with an eerie smile, it growled at him.

--------------------------------------------------

After awhile the Pikachu decided to join after the little situation. He confronted the Spearow flock and showed his power at Pikachu, it look at him with stars in its eyes.

After leaving the flock, he caught a female Pidgey and trained his pokemons and showed them how to fight independently and how to increase their power, it made Pikachu and Pidgey exited while Feebas vibrated.

When Ash was training(torturing) his pokemons, he met someone that unexpectedly tried to assault him, "Hey! What are you doing to those poor pokemons!?" a screech was heard as Ash look back and saw Misty the canon Ash companion.

"Hmm, can you see I'm training my pokemons?" Ash tilted his head at her.

"Huhh!!? All I can see is a trainer beating his pokemons, you should be arrested for such a hideous crime!" she walk to Ash and tried to slap him but her hand was caught roughly.

"Such assumptions will backfire you really bad woman, were having a heavy training session here and you interrupted us, plus were done with training." he sneered at her and forcefully pushed her hands away.

"Don't lie! Because I already saw you beating a Pikachu with your bare hands and you might even never feed your pokemons from the start! " she glared at him hatefully with a stubborn look.

"Hahahaha!! Hey guys this girl here seem to see me abusing you guys, do you agree with her?" he asked his pokemons who just got up after a heavy training session. They look at him in confusion before shaking their head and sat down in Ash shoulder and his head while Feebas stayed at Ash's hands.

"See? You know what you tried there is really rude ya' know and I might sue you for character defamation right? Observe the whole situation before you start accusing others before you regret it later bobo." he flipped her off and gave her a smug face while his pokemons also gave her smug faces.

Misty just growled at Ash before stomping off, 'Geez how did Ash endure her for the entire series I will never know.'

--------------------------------------------------

After that confrontation he continued his journey and training his pokemon, he met the samurai kid and ruthlessly destroyed the battle and it left the kid sadden.

When he arrived at the Pokemon Center he ask for his pokemons recovery while Pikachu didn't stayed at his pokeball.

*POOF!*

"Prepare for tro-" the voice was cut of when Ash command his pokemon.

"Pikachu lightning surge." high powered electric current was released from Pikachu.

*BOOM!!*

"Ahhhhh!!" Ash watched as Jessy, James and Meowth got elctrotheraphy from Pikachu.

He throw a pokeball and caught Meowth, "Umm nurse Joy we should call the authorities for this umm clowns?" he glance at nurse Joy and walked to the two electrified bodies.

--------------------------------------------------

His journey continued as he brutally destroyed every gym battle that most of them started crying(he called Brock a exhibitionist) and won the Pokemon league and became the youngest Pokemon league champion.

It continued after he finished the Kalos region where he met Alan.

Ash didn't catch many pokemon so he only caught few of them which is:

Kanto to Johto

Pikachu

Milotic

Pigeot

Charizard

Blastoise

Lucario(he found an egg.)

Hoenn

Swampert

Salamance

Altaria

Metagross

Sinnoh

Garchomp

Infernape

Frosslas

Unova

Oshawott(he didn't want it to evolve.)

Serperior(he didn't saw the canon Tepig.)

Archeops

Hydreigon

Volcarona

Kalos

Greninja

Talonflame

Ampharos

Some of the major event didn't happened mostly because of his interference(he stopped them from the shadows.) and he didn't get companions.

Misty is annoying, May is a kid, Brock is depressed, Max is a kid, Dawn is on her own, Iris is a bitch, Cilan is cool but depression hits hard(his Pansage was brutally destroyed by his Oshawott.), Selena is on her own journey and Clemont and Bonnie are still in their gym.

He met Arceus the Alpha pokemon, Ash was surprised when Arceus knows that he's a reincarnated. He found about the other parallel world like the original Ash, then what surprised him further is that there is only one Arceus.

Arceus is a singularity, the one his meeting is an avatar and all the Arceus in the parallel world are also avatar of Arceus.

He received a gift from Arceus for preventing the destructions to the world(the legendary incidents didn't happened.), his aura increased in power.

You might ask what happened to those Organizations(example Team Rocket), well most were disbanded, he crippled Giovanni before he busted the whole Team Rocket.

It also happened to the other organizations, Team Aqua and Magma disbanded after all their plans were idiotic, Team Galactic vanished from the world(he send them to the outer space were they died from the lack of oxygen, it may seems this is heartless but those guys causes mass destruction and even destroy the world, he does not follow the good and evil principles.)

Team Plasma disbanded after finding out that Ghetsis and Colress were murdered in their respective room, then the police unexpectedly barge in their hideouts.

Team Flare members were the same as Team Rocket, they disbanded after their leader was crippled and sent to prison.

------------------------------------------------

Pokemon League(Kalos) Finals

Alain vs Ash

"Let the match begin!"

------------------------------------------------

It was Alain last pokemon and Ash third pokemon(he only lost one pokemon.)

"Go! Charizard!"

"Greninja."

They both release their pokemon.

"Charizard! Mega evolve!!"

Alain's Charizard transformed into his mega state. Ash gaze at the transformation and grinned.

"Use flamethrower!"

Charizard breath a huge blue flame as it travels to Greninja, Ash didn't said anything and just smiled.

*BOOMMM!!*

Alain stared at the smoke expecting an injured pokemon only to see a burned crater. A flashing blue light appeared as the Charizard was hit by a water shuriken.

Greninja descended from above and landed on the ground.

"I haven't showed it to anyone but I think it's time to show something cool."

Ash said as he and Greninja glowed blue.

The people murmured in surprise, Sycamore stared at the show eyes wide.

"Greninja! Let's take this to another level!"

"Jahhhh!"

Ash glowed brightly and so Greninja. Suddenly Greninja was covered in swirling water and burst, there stood a Greninja with more features.

Mega Greninja

The people watching the battle gasps in surprise and started cheering for witnessing such phenomena.

From above were two champion sat, Diantha the Kalos champion stood up and stared wide eyes and her body trembling in excitement, while Steven of Hoenn jaw's dropped and eyes sparkling.

"How?...." Alain stared in surprise, never in life he saw a mega evolution without the use of the stones.

"What!!??" prof. Sycamore stood up mouth open and closing with his eyes wide in shock. "Such phenomena!!" he shivered in excitement.

"Don't be surprised, there are other pokemons that can mega evolve without the stones." Ash said with a smug face.

"What an unbelievable sight!! Ash Ketchum showed us an unbelievable mega evolution!! And he said other pokemons can mega evolve without mega stones is this true!!??"

"AAAAHHHHHH!!!!!!"

The croud cheered louder. The champions stared at Ash in surprise while Sycamore began shaking his assistant.

"Water severing waves!" Ash said, as ball of water forms in front of Greninja and high pressurized water burst from it.

Alain came out of his shock and commanded Charizard to dodge.

In the end Ash won the League.

Ash was in the waiting room getting back his bag as two champion and a professor entered.

"Ohh… it's just you guys." Ash said nonchalant and carried his bag.

The people entered the room gape at his nonchalant words.

"Ahem! Hello Ash we meet again, after that fantastic battle I would like to know about your Greninja." Sycamore said with a smile on his face. Ash stared at him and quickly walk to the exit, "Not available.".

"Wait!!" the three screamed and followed Ash as he halt and turned around.

"Fine! It was bond evolution the stronger the bond between you and your pokemon, there's a chance that you can do what I did." he said with an annoyed expression.

"So Steven how was your back?" Ash ask Steven with a knowing smile. He flinched and blushed hard.

Diantha stared at them and dismiss her growing thoughts(she thought they had sex.), "I would like to congratulate you on your battle." Ash stared at her, "Go on." Diantha sweatdrop "Ah–well– I would like to know if I can do it with my pokemons."

"I think you should stop it, the consequences of this evolution is big and might cost your life." he said with a serious expression. "How—" Sycamore was cut off.

"It connects your body with your pokemon, you can feel what your pokemon feels." Ash said.

"So you will feel the pain of your pokemon?" Sycamore muttered in shock.

"Your Pokemons have high pain tolerance while you don't. If your pokemons received big damage from an attack, your body might or will collapse." Ash stared at the silent trio.

"Thank you for the information Ash." Steven said and Ash smirk at him.

"What ever you do, don't the same as me I even fainted for the first time and woke up two days later." thats a lie, he use his aura for the evolution and not connecting the soul(using the evolution the two must connect their soul to form a bond that will boost the trainer and the pokemon will undergo an evolution.).

"See you next time." Ash walks out of the room.

"Hahhh I was really excited of this new discovery, well it is risky." Sycamore sighed and exits the room.

"Well that's it, I just want to know more maybe next time." Diantha soon followed.

"Wait for me!" Steven screamed.

------------------------------------------------

"Talonflame let's go." Ash said and mounted his pokemon. "Talonnnn!!" Talonflame flew at the speed of sound.

In mere minutes they arrived at the airport.

"Thanks bud and get some rest." Ash smiled at his pokemon and took his pokeball, the fire bird proudly raised its wings.

Ash stared at the windows recalling his previous adventure, after this he'll stay home and again, new adventure. He straightened up as a familiar presence entered his mind.

"Choosen one." a majestic voice entered his ear. "Arceus." Ash said, "Is there something you need?"

"I request your help, an old enemy has broken his prison and is on his way to destroy the Universe." Arceus voice carried seriousness.

Ash frowned who is this enemy? "Can I know who's the enemy?"

"Before the existence of Dialga and Palkia there was a pokemon far older than them, Nyxeus the night, he was the night and darkness, his power corrupted his core and started destroying the creation, and so I sealed him of and now he broke his prison and his goal is to steal the core of the choosen one." Arceus revealed. He froze in shock, "Me?"

"When I said that there are many universe, he right now is on the main universe and the choosen one is weakened." Arceus said, "He choose that moment and tried to steal his core, I request you to help the choosen one."

"I haven't told my mom that I'm going home so it's fine and she had Daisy, so I'm in!" Ash exclaimed in excitement. Arceus chuckled, "Be careful Ash he's strong, stronger than my eldest."

"I'll go alone, I'm leaving my pokemons" Ash said as Arceus asked in concern, "Are you fine without them?" Ash shook his head and smile, "I'm far stronger than any of my pokemon and with your gift I'd be safe."

------------------------------------------------

"Are you ready Ash?"

"I'm ready Arceus."

"Very well, I'll open the entrance to the main universe."

A blue spacial portal opened infront of him.

"This will be fun."

He walked inside the portal as it close.
