Ash age: 19 May age: 18

(1 year later.)

The Battle Pyramid flew over Pewter City and landed right next to the small yet lively city.

Two trainers exited the Pyramid shortly after the landing. One was dressed in blue jeans, a red jacket, a black shirt, and a baseball cap his name was Ash Ketchum. Next to him was a Young Woman who was wearing a pair of biker shorts, a white and red blouse, and a white and red bandana.

Ash stopped walking when he reached the exit/entrance of the Pyramid. May noticed this and asked.

"What's wrong?"

" I have to go to Pallet Town."

"But the Grand Festival starts today you'll miss the first few rounds if you leave now," May complained.

"I know, I know, but Professor Oak called me and said there was an emergency over in Pallet Town. He said he needs me."

"And you didn't tell me this sooner because..."

Ash looked at May's angry and mildly offended expression before he said. " I just... I know how much the Grand festival means to you and I didn't want to disappoint you."

May's expression softened. "What am I going to do with you, " May placed a kiss on Ash's cheek. " Go help the Professor but I want you back here as soon as possible, you got that?"

Ash smiled. "Right!"

"I also demand level three reparations!" May said with a smug smile.

Ash just gave her a dry look in response. Reparation was a system that the couple had come up with, the gist of it was that if one them screwed up the other could demand a Reparation from levels one to five. Level three pretty much meant May would have full control of the T.V. for a week. He was going to spend the next week being forced to watch soap operas and romcoms.

The couple went their separate ways with May heading towards Pewter City and Ash entering the Pyramid. Ash quickly made his way to the control room at the very top of the Pyramid and set the coordinates for Pallet Town.

( It will take five minutes to reach your destination.")

" Five minutes huh?"

Ash decided to kill time by visiting the expansive library that the Pyramid had. The Battle Pyramid served as both Ash's workplace and his home or at least until he retired like Brandon it was only recently that Ash officially became the Pyramid King, his graduation consisted of defeating Brandon in a full six on six battle if Ash won then it meant he was ready if he lost then it meant he needed more training. Obviously, Ash won and fairly decisively as well.

He picked up a book and took a seat after five minutes passed he got up and left the Pyramid. Ash approached Pallet Town with Pikachu and a green Espeon by his side, Ash had learned that the little Eevee that his father gave him was similar to Pikachu in the sense that he didn't like his pokeball though Espeon would occasionally, enter the ball if Ash ever entered a crowded place.

Ash found his way to Gary's childhood home where the Professor said to met with him.

"Ash is that you?" Daisy who was Gary's older sister asked.

Ash gave her a nod. " Do you know where Professor Oak is?"

Daisy's face seemed sad and she said " He's upstairs with Gary."

Ash went up the stairs and made his way to Gary's room where he was shocked by the sight that greeted him when he first entered the room. Gary was in his bed and he looked awful both of his legs were broken as and his skin was covered in many bruises. Professor Oak was standing beside Gary next to him was Blaine the Fire-type Gym Leader and ex-team Rocket member.

" What happened to you?"

"Mewtwo happened," Blaine answered.

"Mew what?"

" Mewtwo is a pokemon that was genetically modified by Team Rocket. It was created using DNA from the mythical Mew, he was created to be the perfect killing machine, " Blaine crossed his arms as he felt guilty for everything that was currently happening. Blaine was the head researcher when it came to creating Mewtwo both of them, of course, he had long paid for his crimes by offering to the police everything he knew about the criminal organization but even so, the current situation they were in was all his fault.

(A/N I changed Mewtwo's lore for my story, this one is more like the Mewtwo you find in the games rather than the movies.)

Professor Oak sighed, "It's awful Ash Mewtwo has taken residence in Cerulean Cave a very popular tourist attraction and he's attacking everyone in the vicinity. We sent Gary in to capture Mewtwo and hopefully domesticate it to keep it from hurting others but..."

" I never stood a chance." Gary chimed with a hoarse voice. " I tried fighting it but it completely destroyed me the only reason I'm not dead is because my Alakazam knows teleport."

" What do you want me to do?" Ash asked feeling nervous.

"We need you to capture Mewtwo, there is possibly no other trainer in Kanto capable of defeating it much less taming it."

Ash took one look at Gary's battered and beaten body before saying. " I don't know guys, wouldn't it be better to leave it alone?"

" Ash please, This thing has hurt a lot of people and pokemon you need to stop it," Gary begged.

Ash looked at his childhood friend before saying. "I'll see what I can do."

That's how Ash found himself flying the Battle Pyramid to Cerulean City. He was flying the Pyramid manually rather than letting the autopilot do its job, Espeon and Pikachu could sense the fear and hesitation within him and tried to ease his fears with different methods. Espeon was rubbing himself against Ash's leg hoping that the affection would ease his mind while Pikachu offered him a packet of ketchup.

Ash landed Pyramid close to the city and quickly began making his way towards Cerulean Cave. As he approached the entrance of the cave he was meet with a familiar redhead.

" Ash is that you?" Misty asked.

"Misty? What are you doing here?"

" I could ask you the same thing." She shot back." But to answer your question the mayor of the city ordered me to make sure no one gets inside the cave."

" Funny story I need to get inside that cave so if you could step aside, that would be great."

" Are you insane!?" Misty shouted. "Do you even know what's inside the cave."

" A powerful Pokemon."

"A dangerous Pokemon it hospitalized twenty people and over fifty Pokemon."

Ash gulped slightly at that piece of information. ' Just what have I signed up for. Though if this Pokemon has hurt that many people I guess I have no choice but to stop it.'

" Professor Oak sent me here to capture it," Ash explained hoping that Misty would accept that answer.

" Ash you can't possibly think you can defeat It."

" I can and I will besides its not like I'm going in alone."

"Espeon!"

"Pikachu!"

Both of his companions spoke up as if to prove his point. Misty sighed and said, "Be careful Ash I don't want to send you back to Pallet Town in a body bag."

" Don't worry about me I'll be fine." Misty wasn't sure if Ash was saying this to convince her or to convince himself that it would be alright.

With that Misty allowed Ash to enter the cave. The first problem Ash faced was the darkness of the cave but that problem was solved quickly after Ash ordered Pikachu to use flash, the second problem he faced was the seemingly endless hordes of golbat and zubat that attacked him but they were defeated quite easily by Espeon and his Psychic attack.

After traveling for an entire hour Ash and his companions entered a section of the cave filled with glowing blue crystals Pikachu stopped using Flash after he noticed this allowing the crystals to light their path.

At the center of the section stood a large bipedal, humanoid creature with some feline features. It was primarily gray with a long, purple tail. On top of its head were two short, blunt horns, and it had purple eyes. A tube extended from the back of its skull to the top of its spine, bypassing its neck. It had a defined chest and shoulders, which resemble a breastplate. The three digits on each hand and foot have spherical tips. Its tail was thick at the base but thinned out before ending in a small bulb.

Mewtwo let out a battle cry in hopes of intimidating his foes something which seemed to fail. The group in front of him did not cower instead they seemed to be ready for battle.

Ash threw two pokeballs into the air released a giant crawfish and a eight-foot-tall orange dragon that had a fire burning at the tip of his tail.

"Crawdaunt!" The water/dark type cried as he opened and closed his pincers menacingly.

"Charoaoaar!!!!" The fire type roared.

Ash's current party Pokemon.

Pikachu Lv.88

Espeon Lv.80

Crawdaunt Lv.75

Charizard Lv.85

Snorlax Lv.83

Tyranitar Lv.72

Ash had a rather simple plan to bring down Pokemon in front of him, he would need the assistance of Pikachu, Espeon, Charizard, and Crawdaunt to do it. At the moment he was keeping Snorlax and Tyranitar on the reserves in case he needed to escape.

Ash used his pokedex to scan Mewtwo and hopefully get a better idea of what he was fighting.

???? Lv.70

It was very strong that much was certain not many Pokemon had reached that level of power. He needed to make sure to hit him with everything he had, Ash reached for the necklace that he had wrapped around his neck and touched the Mega Stone that was engraved into it. A strong light emanated from the stone and filled the entire cave blinding everyone momentarily.

When the light had died down Charizard had changed forms. His scales were now black and blue, the fire on the tip of his tail was so hot it was blue, and flames now emanating from the fire types jaws.

Mewtwo attempted to read the minds of the group in front of him in order to predict their next move but his attempts were being by blocked Espeon. Given some time Mewtwo probably could get rid of the interference by the green cat but time was not something Ash would give him.

"Crawdaunt use Night slash."

" Charizard stay in the back and use Dragon Dance don't stop until you're completely powered up."

Both of his Pokemon completed their orders, Charizard spread his wings and took flight and began dancing in the skies while Crawdaunt charged his pincers glowing with black energy.

Mewtwo raised his hand and used psychic in an attempt to stop the charging dark type but it was in vain Mewtwo had never fought a dark type before and was unaware that Psychic-type attacks were worthless against them. Crawdaunt brought his claw down on the artificial legendary and followed it up with another strike to his chest.

"Pikachu use Volt tackle."

The electric mouse began sprinting at Mewtwo while generating as much electricity as he could Pikachu crashed into Mewtwo hitting him in the gut and sending him several feet in the air.

Mewtwo caught himself in the air and used his psychic powers to levitate in the air the psychic brought both his hands together and shot a beam of psychic energy at Pikachu but Crawdaunt jumped in front of his comrade and shielded him from the attack.

Mewtwo getting frustrated with Crawdaunt grabbed five stalagmites using Psychic and launched them at the dark type.

"Pikachu protect Crawdaunt with Iron tail."

With lightning-quick speed, Pikachu hit the Stalagmites just as they were about to hit his comrade. This seemed to infuriate Mewtwo as he raised both his arms into the air and summoned hundreds of stars made of energy and launched them wildly around the area.

Pikachu and Crawdaunt were smothered by the barrage of energy and the explosion that followed the attack sent Ash and Espeon flying in opposite directions.

When the attack faded Pikachu and Crawdaunt were on the ground covered in bruises and burns but Mewtwo didn't care he launched a Psybeam at Pikachu knocking him out and grabbed a stalagmite and broke it over Crawdaunt's head sending him into dreamland.

Mewtwo then set his sights on Ash from what he could tell Ash was the leader of this group so the best course of action would be to kill him.

" What power," Ash whispered to himself as he noticed both Pikachu and Crawdaunt were unconscious from just two attacks.

Mewtwo shot a Psybeam at Ash while he was still on the floor recovering but as the laser inched closer and closer to Ash Charizard had flown in front of Ash and used his Dragon Claw attack to disperse the laser.

"Charizard are you ready?" Ash got back up to his feet and returned Crawdaunt while Espeon used Psychic to pick up Pikachu and bring him over to Ash.

" Dragon Claw!" Charizard flew towards Mewtwo with incredible speed. Dragon dance was a move that increased both speed and strength usually Ash only ordered Charizard to use twice but in this battle, Charizard used it six times meaning both his strength and speed were multiplied by four.

Mewtwo was shooked as Charizard began clawing at him leaving scratches all around his body, Mewtwo tried to strike him down with a close-range psybeam but he was to slow to actually hit the black dragon.

Mewtwo fell to his knees, he had taken a lot of damage in this encounter Pikachus Volt tackle, Crawdaunts super effective night slashes, and now Mega Charizard x Dragon dance powered attacks. It was too much even for a Pokemon on par with Legendary Pokemon.

" End this with Flare Blitz!" Ash shouted.

Charizard flew high into the air and then dived straight down his entire body enveloped in sapphire flames. With a boom, Charizard crashed right into Mewtwo causing an explosion of flames to take place. The winds stirred from the attack forced Espeon to use Psychic to keep Ash and Pikachu from being blown away.

When the flames cleared Mewtwo was revealed to be unconscious his body littered with burns and deep cuts. cuts took out an Ultra ball and tossed it at the unconscious Mewtwo, Mewtwo ball shook threw times before making a clicking sound indicating that Mewtwo had been caught.
