Short Pokémon Fanfic. Been catching up on XY and XY: Kalos Quest, and Ash has actually gotten continuously stronger, earning his 6th gym badge, for where I'm at right now. This is a cross between XY: Kalos Quest, and XY the game. Assume this happens while Ash and company are on the way to Anistar City, and Calem from Pokémon X is already the champion of Kalos. The events of Pokemon X have happened while Ash and company were traveling. Assume that Calem's rivals were different, as Serena, Shauna, Trevor, and Tierno are already in the anime. I hope you guys enjoy.

Calem's Pokemon (my own in my file)

Lucario (Mega): Extreme Speed, Close Combat, Aura Sphere, Dragon Pulse

Chesnaught: Spiky Shield, Seed Bomb, Body Slam, Hammer Arm

Haxorus: Dragon Dance, Dragon Claw, Dragon Pulse, Slash

Xerneas: Thunderbolt, Dazzling Gleam, Moonblast, Outrage

Blastoise (Mega): Hydro Pump, Surf, Dive, Waterfall

Charizard (Mega X): Fly, Flamethrower, Flare Blitz, Inferno

"How much further is it to Anistar City?" Ash asked his friends.

"I'm not sure. I can't really find exactly where we are on the map." Serena answered.

"Hm? Why don't we see if that man knows?" Clemont asked, pointing to a man resting against one of the trees in the forest they were walking through. The man was wearing black pants, red sneakers, a yellow poké ball hoodie, and a black poké ball logo cap. He was still decently young, maybe 15 or 16. Ash and the others walked up to the man.

"Excuse me, sir…" Serena began, tapping the man on the shoulder.

"Mm?" he asked groggily, slowly waking up.

"Um, sorry to disturb your rest."

"Huh? Oh. Don't worry about it, I've been here for a while now. I should get up anyway." he said, slowly standing up and rubbing the back of his head. After regaining his composure and fully waking up from his rest, the young man looked back at them.

"Well? Did you need something from me?" he asked, politely.

"Yes, do you know how far it is to Anistar City from here?"

"Of course. I can fly you there, if you'd like."

"Fly us there?" they all asked in unison.

"Sure. My Charizard and I can take you there. The name's Calem. Nice to meet you." he smiled at them.

"I'm Serena."

"Bonnie."

"Clemont."

"Ash."

"Clemont? Aren't you the Lumiose gym leader?"

"Y-Yes. Does that mean you're a trainer as well?"

"Yes. I challenged and defeated Lumiose a while back. But I battled against a robot, not you."

"Oh, so then how many badges do you have?" Ash asked as Calem called out his Charizard, and everyone climbed on.

"Eight." he responded, taking out his badge case and displaying all eight gym badges, shocking everyone.

"So you have enough to challenge the Pokémon League then!" Bonnie exclaimed.

"I already did, and won. I'm the Kalos Champion."

"What?! But I thought Diantha-"

"I defeated her and took her title a few months ago. You didn't hear about that?"

"N-No. Wow, for a trainer to be able to defeat Diantha in a one-on-one pokemon battle…" Ash muttered to himself. Charizard then landed in Anistar City at the large sundial.

"Well, here we are." Calem told them.

"Thank you so much, Calem." Serena smiled.

"Sure thing. Ash, right? Are you going to challenge the gym here?"

"Yes. Anistar will be my 7th gym badge!"

"I see! Then you're quite an accomplished trainer already, aren't you?"

"Well, I don't want to brag, but I've been training really hard to get strong enough to take on the Kalos League!"

"I see. Then I look forward to the day when I face you in battle."

"Wait a second."

"Hm? What is it?"

"If it's alright with you...I'd like to have a pokemon battle with you now!" Ash challenged.

"Hm...alright. This could get interesting. Show me what you can do, Ash. Clemont, would you mind being the referee?"

"Of course!" he said, moving away from the two of them.

"Any preferences for the battle, Calem?" Clemont asked.

"Hm...Ash, how many pokemon do you have with you?"

"Let's see...Pikachu, Noibat, Talonflame, Frogadier, and Hawlucha. Five. But Noibat isn't strong enough for battles yet."

"Alright then. I'll let you use your four pokemon against me. I'll use three."

"But that's not fair to you!" Ash complained.

"It's plenty fair. Trust me."

"...If you say so. Alright! Let's start this off! I choose you, Hawlucha!" Ash called out, throwing the pokeball into the air. Hawlucha appeared and did a somersault midair before landing on its feet with it's wings outstretched.

"Hawlucha, huh? Why don't you take care of this, Haxorus!" Calem shouted, tossing a pokeball of his own into the air, and Haxorus leaped out and landed on the ground heavily.

"Haxorus? I've never seen that pokemon before." Serena said, taking out her pokedex.

Haxorus, the Axe Jaw Pokémon and the evolved form of Fraxure. Haxorus is normally considered friendly. Its body is covered with a tough armor, and its tusks cannot be broken.

"Ready when you are, Ash." Calem told him.

"Alright! Hawlucha, let's start this off with Karate Chop!" Hawlucha's arms began glowing white, and it rushed towards Haxorus.

"Haxorus, catch it." Calem told his pokemon calmly. Haxorus effortlessly held out its arms and caught Hawlucha's attack head-on.

"What?!" Ash yelled.

"Throw it." Haxorus lifted the pokemon off of the ground, and tossed it back to Ash. Hawlucha hit the ground along the way a few times.

"Hawlucha, are you okay?!" Ash yelled. It acknowledged its trainer.

"Great! Then let's keep it up! Use Flying Press!" Hawlucha flew into the air, and was about to slam down on Haxorus.

"Haxorus, use Dragon Dance." Haxorus became surrounded in a dark aura, increasing its power.

"What kind of move is that?" Bonnie asked over from the side.

"Dragon Dance is a move that increases the power and speed of dragon type moves. Let me demonstrate." Calem answered for her. "Haxorus, use Dragon Claw!" Haxorus' claws extended, and glowed green. As Hawlucha fell towards Haxorus, he slashed his claws at the pokemon, causing a lot of damage to Hawlucha.

"Now use Slash!" Haxorus' claws lost its green glow and began to glow white instead. It once again slashed Hawlucha, making it fly across the ground and back to Ash.

"Hrghh...it's strong. We haven't landed a single blow yet! Are you still good, Hawlucha?"

"Lucha!"

"Great! Then let's start turning this battle around! Use High Jump Kick! Max Power!" Hawlucha flew at Haxorus at an unbelievable speed.

"Mm! Haxorus, use Dragon Claw-" But this time, Hawlucha became too fast, and its foot slammed into Haxorus with a lot of power. Haxorus braced itself, and was blown back a bit, but quickly recovered. Hawlucha, on the other hand, was almost out of power, and was just barely able to hold on.

"It's the end of this round! Haxorus, use Dragon Dance, and then follow up with Dragon Pulse!" Haxorus obeyed, and became encased in the dark purple and red dragon-type aura again, raising both its attack and speed even further. Then, Haxorus fired a purple and gray beam of energy towards the battle-worn Hawlucha, creating a large explosion and a cloud of dust. When it finally cleared, Ash saw his Hawlucha on the ground, unconscious.

"Hawlucha!" He returned it to his pokeball. "You were excellent, take a nice rest. Alright, Calem, time for my next pokemon! I choose you, Talonflame!" He tossed another pokeball out into the arena, and his Talonflame appeared.

"A Talonflame? I have one as well, you know. It's back at my home right now."

"Really?" Serena asked.

"Yep. I'm going to stay with Haxorus for now, if you don't mind."

"Fine by me!" he acknowledged. 'But this time, I'll really have to do my best to take down his Haxorus. At least now I know how strong it is…'

"Talonflame, let's start this off with Steel Wing!" Talonflame's wings glowed white, and it flew towards Haxorus at an even faster speed than Hawlucha did before.

"Haxorus, use Slash!" Calem yelled. Once again, its claws became white, and it slashed at Talonflame's wings when the pokemon flew towards it. They clashed, but Haxorus was actually blown back and injured.

"Hm!" Calem looked surprised.

"It looks like your Haxorus' claws aren't as strong as steel!" Ash said confidently. "Now Talonflame, use Flame Charge!" Talonflame became coated in fire, and it flew towards Haxorus once again.

"Haxorus, jump up and use Dragon Pulse!" Haxorus jumped high up into the air towards Talonflame and shot a Dragon Pulse beam towards it.

"Dodge it!" Ash yelled. Because Flame Charge increases the speed of the user each time they use it, so it was fast enough to dodge it, and then slam Haxorus into the ground.

"Haxorus!" Calem yelled out.

"Great work, Talonflame! Now, finish this off with Brave Bird!" Talonflame cried out, and began to glow blue. It sped into the ground towards Haxorus with a golden aura. A large explosion imploded from the ground. After a few seconds, Talonflame flew out, and landed next to Ash again. Haxorus appeared unconscious.

"YES! Great job, Talonflame!" Ash congratulated.

"Return, Haxorus. You were amazing out there." Calem smiled at the pokeball. "Alright, then. Why don't we get serious now, Ash?"

"That was only a warmup for him?!" Serena asked nervously.

"Time to defeat his Talonflame! What do you say, Lucario!" Calem tossed out a pokeball and a Lucario appeared from it.

"A Lucario?!"

"Right. And as you have six badges, I assume that you've met and defeated Korrina at the Shalour Gym, correct?"

"Yeah, that's right!"

"So then you've beaten her Lucario. She used to have two, you know? But when I beat her, she decided to give me one of them. This is the same one." I said, patting Lucario's head.

"And it's much stronger than hers, I assure you." Calem raised his hand into the air, revealing a black mega ring and keystone on his wrist.

"Is that…?" They all wondered.

"Lucario, it's time for Mega Evolution!" Calem yelled out, tapping the keystone with his fingers, causing both it and Lucario to glow. The glow disappeared, and it stood there as Mega Lucario.

"You say you're fast, Ash?! Then let's see if you can keep up with us!" Calem yelled, grinning. "Lucario, Extreme Speed!" he announced before Mega Lucario became a blur and instantly knocked Talonflame into the sky and attacked it four times.

"Talonflame! Get ahold of yourself!" Ash yelled, and his Talonflame recovered.

"Great! Brave Bird!"

"Dragon Pulse." Mega Lucario charged up a beam of rainbow energy and blasted it at Talonflame's Brave Bird. The two powers clashed, but even though Talonflame was injured, it kept flying towards Lucario."

"Close Combat!" Lucario quickly appeared in front of the large flame bird and knocked it straight out of Brave Bird with a powerful kick. It then proceeded to deliver a series of fast and powerful punches and kicks to the bird, knocking it back again.

"Finish it with Aura Sphere!" he yelled, and Lucario charged up and compressed an enormously powerful ball of blue energy, firing it at Talonflame, and creating a huge explosion, knocking the pokemon out.

"Talonflame! Return!" Ash returned it to its pokeball.

"It's your turn, Frogadier!" He sent out his water type. But once again, Lucario quickly took it down just like the others.

"Return, Frogadier. Great work. Calem! It's time that I finished this! Pikachu and I have taken out Korrina's Mega Lucario before, so we'll take yours out too! Pikachu, are you ready!" he yelled, as his most trusted partner jumped down from his shoulder and ran into the arena. Many people were watching the fight around the arena, and were cheering loudly. Calem turned to them, confusing Ash and the others for a second. They all quieted down, willing to listen.

"Let me tell you all something! This man here, Ash. Of all of the challenges I've ever had, he stands out among them. Because unlike the others, he didn't give up during the battle, knowing that they wouldn't win. Even though the situation is dire for him, Ash still believes in himself and his pokemon, and he still believes that he can win! And to me, that's more important than strength!" Ash and the others smiled.

"So as a sign of respect to him…" Calem returned his Lucario to its pokeball, and took out another one. "I'll finish him off with my most powerful pokemon. Charizard, let's do it!" He sent out his Charizard, and it roared when it landed on the ground.

'Great. Charizard's also a flying type, so it will be weak to Pikachu's electric attacks.' Ash thought, smiling.

"I can read right through you, Ash." Calem said, startling his opponent. "If you think that Pikachu's electric moves will give you an advantage, you're dead wrong." Calem held up his mega ring again. He tapped it, and Charizard began to glow, making Ash and his companions shocked, and everyone else excited, knowing that the new champion was revealing his full power. When the light cleared, Charizard stood in a new form entirely. It was now black and blue, with blew fire spewing from its mouth. It's wings had taken on a different shape as well, and its claws were sharpened. Its eyes gave off an ominous blood red glow.

"For you see, when Charizard mega evolves, it changes types from a fire flying type to a fire dragon type." Calem smirked confidently. "Mega Charizard, use Flamethrower!" Mega Charizard unleashed a blast of blue fire towards Pikachu.

"P-Pikachu, dodge!" Ash yelled desperately. Pikachu quickly dodged the fire, but it still made a massive shockwave across the arena.

"Use Thunderbolt!" he yelled. Pikachu blasted lightning, and Charizard got hit by it, but then shook it off as if it was nothing.

"W-What?!" Ash yelled.

"Mega Charizard, use Flare Blitz!" Calem announced. The black dragon breathed some fire, then spun around it using the power of its wings. The fire grew stronger and stronger, until Mega Charizard blasted it towards Pikachu.

"Pikachu, counter it with Electro Ball!" Pikachu created a ball of lightning with its tail, and launched it off towards Charizard's attack. However, the attack was instantly disintegrated, and Pikachu was annihilated by the Flare Blitz. It flew into the air, and fell back onto the ground.

"Pikachu! PIKACHU!" Ash yelled. Pikachu slowly got up to its feet, and fired one more Thunderbolt at Mega Charizard.

Calem sighed. "Charizard, finish this up with Inferno." Mega Charizard flew behind Pikachu faster than anyone could react to, and engulfed Pikachu in a column of raging blue fire. When the attack subsided, Pikachu was knocked out, laying on the ground. Ash walked over and picked him up.

"Pikachu...take a good, long rest buddy. I guess we weren't ready for this battle yet." Ash smiled at him, and looked over to Calem. Charizard returned to normal, and was returned to its pokeball by Calem. The Kalos Champion walked over to Ash and extended his hand out.

"That was good, Ash." he smiled. Ash shook his hand.

"Man, you weren't kidding when you said you were stronger than Diantha. That kind of power was crazy." Ash sighed.

"Ash, I should warn you." Calem told him. Ash looked over at him.

"You might be able to defeat Korrina's Mega Lucario without it, but...you won't be able to beat me without having a mega evolved pokemon of your own. Lucario and Charizard aren't my only pokemon that can mega evolve. I also have a Blastoise that can."

"...I get it. Thanks for the tip, but...no." Ash told him.

"What do you mean no?"

"You may think so, but I know that I can beat you without using Mega Evolution. I'll beat you with my own power." Ash smiled at him.

"...Alright. If you think you can, then be my guest." Calem smiled back at him. And with that, they said their goodbyes, and the new champion of Kalos went off to prepare for the day when Ash would challenge him once again.

End.

One of the things that I wished they had done in X and Y is change Mega Charizard X's fire-based attacks to be blue, instead of keeping them red. They do that in the anime, so I decided to add that element in here as well. I hope you enjoyed it!
