This is my first attempt to make a story so please be kind, critics are welcome just avoid insulting, I will try to improve but it is not something I can promise.

If you are in a part where you think there is an error because of the times in which certain events happen, my answer is this, this is a FF and even in the original story time does not make much sense. I am tempted to do a prequel (One-shots) for certain events...

Also consider that my native language is Spanish, so if you notice mistakes in spelling or sentences that are not well articulated, excuse me, I will try to make sure they are not too many and correct what is possible.

This Ash is a little smarter and has learned some tricks from his friend Brock and Professor Oak. Also to say that he has a lot more Pokémon and they will be stronger than they are in canon.

Max didn't accompany them in Hoenn, he was 5 at the time.

Bianca was his only companion through his journey in Unova.

Mewtwo (Kanto) joined him after the events of the movie. Mewtwo (Unova) also follows him after her movie.

He captures legendary that don´t have responsibilities and need friends. Ash has never used legendary Pokémons in an official fight. They are always out of their Pokeballs and they are almost always at New Island. Pokémon Professors, Charles Goodshow and Looker know about them.

New Island it´s where all his Pokemon live, also some business partners like Kidd Summers, Banks, Bill, Tobías, Butler, TR (Jessie, James y Meowth) and a nurse Joy.

Latios (movie) is alive, Lucario (movie) is alive, he stayed with the queen.

Lucario taught Ash Aura, Alicia taught Ash Oración.

He maintains communications with Looker (International Police officer).

He helped destroy Team Rocket (Unova), all were apprehended.

Jessie, James and Meowth were apprehended since Kanto League, Giovanni sent Domino to get rid of them, they were able to flee and then they worked for Bill.

Ash has a PokéNav Plus, Xtransceiver and a Laptop to teleport Pokémon (courtesy of Bill).

16: Ash, Gary, Paul,

15: Lyra, Serena,

11: Shauna, Tierno,

10: Trevor, Sawyer

8: Max, Bonnie

We will use the version that says that if you capture a seventh Pokémon the Pokeball will shrink and cannot be used until you change your team, you can do that with the Pokedex.

There is no limit of movements that a Pokemon can learn, it is only difficult to know more than 4 at a time, but with training there are no limits to the potential of a Pokemon. Why do I take it like this? The difference between a common action and a Movement bothers me a lot, I thought a lot about how to take this topic, but it just does not come to anything, so I'll use the excuse of unlimited potential.

TMs exist, TM moves can be taught, but they are harder to learn, the same with Tutor and Egg moves.

For this story Ash will be 16 years old. I imagine that the cycles of the leagues work something like this:

League season (8 m/4 m), Championships (?), Battle Frontier (4 m/8 m).

The outfit of the characters is the same as in the original story. Just to be clear neither Bonnie nor Clemont will go with Ash.

Now the usual:

"Speech"

'Thoughts'

"Telepathy"

A walk through Kalos

In the faraway region of Kalos an airplane started to descend to land, in this airplane a young man with a his companion, a yellow rodent, couldn't wait to explore this new region full of new Pokémon to catch.

This young man is the famed trainer Ash Ketchum, this 16 year old trainer is considered a prodigy who has won 5 regional leagues, the championship of the orange islands and won the title of Master of Kanto's Battle Frontier, in these days in the regions that know of him people sometimes said that he was a Wandering Champion, someone who although never took the challenge of the Elite Four, had faced members of this group and had emerged victorious in more than one occasion and now his goal would be to win the Kalos league, among other things.

One would think that after these years of traveling, knowing the world with everything and its bad side, this young man would lose the emotion for such simple things. But although he has matured in many areas and even now has his own dark side, this young man still retained much of his innocent side and one of the things he retained was getting excited to meet new members for his extended Pokemon family.

The only thing that could take away his good mood would be that some new evil organization was trying to control or destroy the world… something that seems to be happening… again.

Already with his good mood destroyed, he closed his eyes and concentrated a little to make contact with a friend.

"Mew-ten can you hear me?... Mewten? Hello? Mewten?... *sigh* Mewtwo from Kanto?"

"Yes Ash, I can hear you" A not so amused voice replied.

"You know if you despise so much the nickname that I gave you, then create one for yourself, you know that if I just say Mewtwo we're going to have misunderstandings with Mew-shiro, she did accept the nickname I gave her and she knows that it is better for our communication"

There was a great pause in which nobody spoke… thought… transmitted.

"… OK, I understand the need for the nickname, tell me you already arrived at Kalos?"

"No, but we are already landing, prepare the Search Team that we had discussed, as soon as I am in a safe location I will contact you again… and stop being so fussy or you will never get her love" You could feel Ash smirk in his words… thoughts.

"You know I can make you think you're a Magikarp, right?" And now it was Mewten smirk that Ash felt in the conversation.

"See ya" Ash intelligently thought this in an intimidated tone.

Ash did not know why but it bothered him to hear Pikachu laugh a few seconds later.

Hotel Richissime (30 Minutes later)

We can see our hero walking, with his 5ft 11in height, to a hotel where he will stay for the next few days, this will also serve as a base of operations for the team that will arrive. Asking for a room with two beds, he goes to his room and gives the signal for Mewten to send the rest of the team. After a white light in the room appeared 3 humans and a talking Pokemon, these were Kidd Summers, Meowth, Jessie and James (these last two were in civilian clothes).

"You took a lot of time muscle head" It was the greeting that he heard from the redhead, the bluehair and Meowth, while the one with brown hair just smiled in amusement.

Pikachu released a little electricity from his cheeks in annoyance and Ash just shook his head in exasperation and then started unpacking his luggage "Yeah sorry, you have all the necessary equipment?" He asked without lifting his head from his suitcase.

"Of course, you're dealing with professionals! ... and Bill would kill us if we lost any of his devices..." It was the response that gave the cat of the team who barely and whispered the last part.

He trembled a little and gave them a smile of empathy, of course he would not say anything against the inventor, the last time he said anything about his devices one of his machines "accidentally" turned him into a Caterpie, don´t misunderstand him, he liked the inventor but sometimes his temperament was ... volatile by putting it slightly.

Shaking his head to disenchant unpleasant memories, he stood up taking his special backpack and went to the door and prepared to leave the room, before leaving turned on his shoulder and said

"Unpack and prepare the equipment, I will visit Professor Sycamore, we will stay a few days in the city and when we finish analyzing the readings of the stones you will begin the search for more stones and the vigilance of Team Flare, try not to call much attention, you know that for me that will be impossible" With that said he went to the door, he opened it and left the room.

"Who does he think he is? Just because he grew a bit doesn´t mean he can boss us around" Jessie said with a twitching eye.

"Come on, let's prepare the communication devices, it will be a long day and we have to be ready before the end of the night or Bill will be… curious" Kidd said while unpacking her own luggage.

Streets of Lumiose City

On his way to Professor Sycamore laboratory, the black-haired young man had the luxury of admiring the city a little, the size of this was impressive, few cities he had visited could compare, he was sure there were many more cars in this city compared to those in the entire Kanto region, well the Kanto region that he knows, for which he traveled again a little over 2 years ago.

When he arrived at the laboratory front he had to admit that this was the best presented of those he had seen from the regional professors, but for a laboratory it is not what they look like but what activities are carried out within those that matter.

Passing the door he began to observe the interior, each time seemed less a laboratory and more a huge house, before he was lost in his thoughts, he set out to find someone to attend him, closing his eyes a moment and concentrating he let his Aura click through the whole building, he detected many Pokémon playing, flying and some eating, 2 people, one feeding the Pokémon and another on the second floor... sleeping while sitting. Suppressing a laugh, to which Pikachu raised an eyebrow, he climbed the stairs to the person on the second floor.

Approaching the room and knocking 3 times on the door, he waited for an answer, but when he saw that it will never arrive, he opened the door and entered to be greeted by Professor Sycamore drooling on one of his books, this time he could not help laughing and now Pikachu accompanied him but even that did not seem to be enough to wake up the tired Professor.

Deciding to take pity on the poor Professor (not before taking a picture) he went to wake him up, for a second he considered letting Pikachu give him a little shock but in the end opted against it, not everyone has electrical resistance, so he just shook him a little.

"Professor Sycamore… Professor Sycamore wake up!" He tried this for a few seconds before it worked.

"Hello young man, who are you and why are you in my office?" Professor Sycamore said while blinking several times trying to wake up completely.

"Good morning Professor Sycamore, my name is Ash Ketchum and I have come from the Pokémon league to discuss the issues that you reported were occurring in Kalos" He replied with a serious tone.

Professor Sycamore eyes widened.

Vaniville Town (Morning of the next day)

In the small Kalosian town of Vaniville there was one person sleeping. This person was an old acquaintance of our hero, although she would like to be much more than just an acquaintance, but fate has separated them for many years. This young woman is Serena Yvonne Gabena future Rhyhorn racer or at least that's what her mother trains her in, many times she has considered telling her mother that it is impossible for her to dedicate herself to that, but without a fixed goal it is difficult to refuse the help her mother offers her on a possible path.

While she slept peacefully on her body pillow (with the design of a certain person) she did not realize that a certain bird approached with the intention of waking her from her sweet dreams delicately…

"AAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHH FLETCHLING YOU ARE DEAD BIRD!"

Her scream was heard by her mother Grace who was in the kitchen making breakfast for her daughter "I guess some things never change" Grace said while shaking a little her head with a fond smile.

After a few minutes of chasing and curses being thrown…

Serena finally calmed down and began to prepare to start her day, which she feared would be to try to ride Rhyhorn again. Serana took a bath, changed her pajamas for comfortable clothes and started brushing her hair, while she looked in the mirror, she could not help but wonder what Ash would think of her hair.

Ash Ketchum was the subject that every time it was mentioned it brought a blush to Serena face, they had not seen each other in person since they were children, and she honestly believed that she would not see him again, but since coincidentally she saw Ash's confrontation with Tobias in the Lily of the Valley Conference (not that it was very difficult to see the battle, they broadcast it repeatedly on television), she dedicated herself to look for Ash's information in the Pokénet, there she discovered that he had spent time dedicating himself to fulfill his dream to be a Pokémon Master.

The first thing to jump into view were his victories in the Pokémon Leagues, the second was the Ash merchandise that was sold at acceptable prices… later she found his victory in something called Battle Frontier and that he won the championship of some region called Orange Archipelago (not that she understood that part very well), but it is not as if his victories were reduced to that, there were many other competitions that he had apparently won.

When she started to run out of things to investigate about Ash (she found quite strange rumors that were simply impossible) she realized that she did not want to simply know what he was doing, but to be part of his life again, so she set out to travel to where Ash was to get in touch again, so she thought about how she could locate him or contact him and after talking with her mother (which was very embarrassing) she got the number of Ash's mother.

The day she set out to call Ash's mother was one of the longest of her life, the reason? She took a half day to fix her hair and a dress that she considered sufficient to meet her possible mother-in-law, even if it was only by video call.

The call turned out to be quite simple and short, they greeted each other and talked a bit about how they had been and she asked how she could meet Ash again…

Until today Serena is sure that she has not had more fear in her life than when she saw the face that Delia Ketchum did, the mischievous brightness in Delia Ketchum's eyes and the sweet and inoffensive smile she put on sent a chill through her body, and the last words she heard before Delia hung up were:

"Leave it to me"

After that video call her mother told her that she had talked with Delia several times afterwards, which only made her more nervous and she promised that soon she would see Ash, of this it has already been 2 months, but Serena cannot accumulate enough courage to ask her mother more.

Finishing with her hair and making sure she was ready, she went down to breakfast but not before hiding her body pillow.

"Hello Serena how do you feel on this beautiful morning?" Grace had a playful brightness while saying this and this did not pass unnoticed to his daughter who could only start to fear.

"I feel great Mom" She answered in an insecure tone.

"Great, does it mean you're ready to have some exercise?" Grace wanted to have some fun with her daughter, she is her mother so it's certainly normal to do it, right?

Serena couldn't help but groan "But mom my back still hurts from yesterday's falls, cannot you let me rest today?"

"Mmmmhh so you're in pain? It's a shame really, I was going to let you go see Ash in Lumiose City"

The world stopped for Serena, suddenly she was in a world of warm and beautiful lights, out of nowhere Ash appeared and invited her to dance, she accepted with barely contained emotion, while dancing they began to float and kept floating until they could see all Kalos, Ash smiled at her, hugged her tightly and said "Serena, Serena daughter, can you hear me?" And with that Serena came out of her fantasy and saw her mother's face.

Grace was mainly entertained by her daughter's performance, although she could not help but worry about her, she never pressured her to anything and knew that if she had proposed that she travel after she turned 10, the only thing she would get would be for Serena to be hurt, so this time helping her in her little romance would also help Serena become a little more independent due to the trip but having someone reliable to protect her.

"Well Serena, do you think you can walk to the laboratory in Lumiose City to get your first Pokémon? Ash will be there a few days and it is almost certain that you will meet him"

Serena ran out of her house wearing different clothes than she had during breakfast in less than 10 minutes.

Prism Tower

On one side of the Prism Tower a hatch was opened, from it came two blond brothers screaming for their lives and a rabbit with a deadpan expression.

"AAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHH"

Apparently the gravity did not hear their prayers and continued with its function, make them hit the ground, the older of the two made the decision to sacrifice himself for his little sister and threw his impact bag in the direction she was falling, satisfied with his role as elder brother, he smiled, closed his eyes and waited for the end, and waited and waited and waited, when he did not open an eye to see what happened, for a moment he stared at the blue sky and then turned to look down and found his new friend Bunnelby holding him before giving him a weak smile, leaving him on the floor and done this he fainted.

(A/N: You wonder, how did the column not break or something like that? The answer is really easy: Pokémon)

"Oni-chan are you okay?!... Oh no! Bunnelby is wounded we have to take him to a Pokémon center!" Bonnie having left the state of shock, began to worry about something else than her life.

Although Clemont took 1 second more than his sister he also left his shock

"The Pokémon center is far away, it´s better to take it with Professor Sycamore"

Professor Sycamore's laboratory

While Pikachu slept a nap Ash was reviewing some of the data they had collected so far about the mega-stones 'Arcs of energy leave the stones that possess the Pokémon and the Trainer, join and then the stone of the Pokémon absorbs them... Could that be…? I need to see the process myself'

"We need help please!"

A cry for help prevented him from remaining immersed in his thoughts, Pikachu climbed on his shoulder without any order and he quickly climbed down the stairs to see what was going on, what he saw was a little girl in panic.

"What is the emergency?" Ash answered in a serious and calm voice, avoiding panicking like the girl.

"You have to help Bunnelby, he's hurt!" The girl that Ash believed could not be 10 years old, so that she already had a Pokémon, kept repeating.

"But where is he?" Ash had just finished saying that when a tired Clemont came in through the lab door with Bunnelby in his arms.

Between gasps Clemont tried to vocalize the problem "electricity…*gasp*... fall…*gasp*... "

Ash quickly took the Pokémon in his arms and took him to the recovery room, Clemont and Bonnie followed him, halfway there he found Professor Sycamore's assistant and explained the situation, she took the Pokémon and placed it in the recovery chamber. After a few minutes treating him Sophie informed them "Do not worry Bunnelby will be fine he just needs to rest for today"

There was a great sigh of relief in the room

Streets of Lumiose City

Serena could not believe her luck, she would finally see her childhood friend again (she does not care if they met for a short time, Ash said they were friends so they are friends), Ash was always someone Serena admired, with the short time she knew him was enough to see and feel the great amount of passion and willpower that he possessed. That now said friend with great qualities is 10 times more handsome it only added to her delight and her nervousness.

'Seriously any girl who was in her 5 senses would try to get a piece of...' That thought stopped Serena's good mood and increased her concern. And now that she thought it over, Ash had a fan club, several times she was seen regularly accompanied by other girls (it was suspected that they were with him), but Serena had never seriously considered what would happen if Ash was already interested in another girl.

Serena shook her head violently, that kind of thoughts did not serve her at all, and if she wanted to be someone who could walk by Ash's side she should have enormous willpower and doubting that way is counterproductive. Serena decided, she would do everything in her power to be the equal of Ash, after that if the situation occurs in which he will already have someone else ... well at least she will feel that she will continue to have part of his heart for her, though anyway 'I really would like to spend all my life with him'

Seeing that she had arrived at the laboratory, Serena steeled her resolve before entering.

"Heeellooooo Professor Sycamore, I'm Serena, I came for my first Pokémon" Serena raised her voice for someone to hear her.

Turning around the corner of a hallway Professor Sycamor smiled at her "Ah Serena is good to see you, right now your mother just called me to let me know that you would come, please come with me I will show you the options you have for your first Pokémon"

They both walked to the back of the building, entered a room and the Professor took out 3 Pokéball and threw them into the air at the same time.

"These are your options Serena" Professor Sycamore began "Ches-"

"I choose Fennekin" Serana was already hugging the little vixen while Fennekin licked her face happily.

"Well that was ... fast" Sycamore cleared his throat and returned to the other two Pokémon "Well Serena now this is your Pokédex and Pokéball to catch more Pokémon" Sycamore offered a tray with the equipment.

Serena took the offered equipment and she was going to return Fennekin to her Pokéball, when she heard the voice of a girl. "Come on I want to see the Pokémon!"

At that moment Bonnie came through the door followed by Ash and Clemont.

"Sorry Professor, we told Bonnie that she had to wait but she did not listen to us." Clemont apologized for the behavior of his sister.

"Oh don't worry, Serena let me introduce you to Clemont the gym leader of the city, his little sister Bonnie and the young man in the cap is Ash"

"Nice to meet you Serena" Clemont, Bonnie and Ash said at the same time, showing a smile. Serena also smiled but inside she felt sad, Ash did not recognize her, they certainly knew very little time but she expected him to recognize her.

Serena was going to answer but suddenly in front of her was Bonnie on her knees "Serena what a beautiful name, you wouldn't want to-"

Anything she was going to say was interrupted by her brother covering her mouth even with the protests of Bonnie "Hehehe excuse my little sister, she always says things that she does not have to say" He turned to see Ash "Ash we will wait for you in front of the tower and again thank you for offering to help" And with that he ran out of the place with his sister in his arms.

"Well, that was strange" Ash murmured "I'll be back in a moment Professor, I offered to help Clemont with his problem, see you later Serena" Ash said and went to the door.

"Wait Ash" Serena stopped him before he left "I would like to go with you"

Ash gave the best answer his brain could produce "HUUH?"

OMAKE: Pikachu in Kalos 1

Pikachu awoke from his long lethargy, to be honest he would have preferred that Mewtwo simply teleported him afterwards with others, he was the main protector of Ash, but these long trips made him feel bad, the only thing he could do was sleep and eat (if Ash did not have it on a low ketchup diet it would suffice to remove the bad mood).

When he turned to see his Trainer, he had a concentration face, which is specific to the telepathic connection, but he also saw several emotions go through his face, when he saw the last, one of fear, he worried if something would happen, so the contact to Mewtwo when Ash finished.

When the end of hearing the short story could not help laughing, Ash still had much of his innocent side apparently, Mewtwo would never hurt Ash (voluntarily again), for Mewtwo Ash was what one should strive to be: compassionate, kind, tolerant, fair, honest and loyal. And also very silly sometimes but that was part of his charm (proof was the TENS of female humans who have met on their trip and who wanted him as a companion).

Sometimes Pikachu was also astonished with the qualities of Ash, Ash has resisted enough offers of power, including that of a temporarily unbalanced Mewtwo, proposals to make him practically the King of this world and Ash did not hesitate a second to reject them. Being honest Pikachu did not know if he could resist something like that ... All the ketchup he could eat...

Moving on to other topics Pikachu asked Mewtwo how the bets were made (how many girls would fall for Ash on this trip) and he could not help but laugh again, although apparently Ash was starting to notice, so he should leave the conversation with Mewtwo about how to make a personal harem to Ash for later.

…..

When they arrived at the hotel the first thing that Pikachu did was to throw himself to the bed, he was certainly used to being in Ash's legs and shoulder but this was much more comfortable.

After a few minutes another group of humans appeared and Pikachu could not help but curse his luck that his rest was so short, so he quietly climbed onto Ash's shoulder, some of these fools were once criminals and although Ash now relied on them, Pikachu would never totally lower his guard, he knew that it was the same for Mewtwo.

And they were still annoying at times, proven by the comment of the redhead character (even he could not believe that the blue haired idiot married her, that human seems to like to be shouted).

…

Pikachu was resting on a sofa in the lab, it was not as comfortable as the luxurious and expensive hotel bed but it served its purpose, when he heard the scream asking for help he simply shared a look with his soul brother and climbed on his shoulder, thinking curiously if they would already know the first girl who would fall for Ash.

A few seconds later and it would seem that it would not be the case, Pikachu did not understand very well the age of the humans but even he noticed that this human was too young for Ash.

….

The blond-haired boy was nice, if a weakling, but Pikachu knew better than just judging by a human's physique, Ash at first had been almost as puny as the blond boy and still had enough courage to face creatures considered by many as gods.

Besides if what he understood well, the boy was an inventor and if something Pikachu has learned from frequenting Bill, is that the inventors can get to create machines that rival the gods.

Something he has seen sometimes, Giratina still mentions how much he enjoyed when he killed the lunatic who tried to get his power, well Pikachu would have enjoyed it too, the damn bastard killed Ash, although Giratina used a strange ability afterwards to revive him, it still counts.

I hope you enjoyed the first episode, as I mention I accept criticisms but please do not be with insults, I cannot stand them.

These are the Pokémon that I have thought for Ash in Kalos

Chesnaught, Delphox, Greninja, Talonflame, Florges, Aegislash, Malamar, Hawlucha, Goodra, Klefki, Trevenant, Noivern.

I'm quite happy with the ones I select, but if you have any suggestions, feel free to give it.

If you have questions about how Ash came to be what he is, ask them, I'll answer as best I can.

First I had thought about starting from Hoenn, but a look towards everything that I had to rewrite and I regretted, maybe someday I would be encouraged to do Unova (Giovanni, Ghetsis, N, etc.).
