"Mega-Ventures of Remnant"
Chapter 1: Intro + Yang Xiao Long
Present Day: Beacon City Pokémon Center, 8:50pm.
A man, wearing a white coat and a black bowler hat, walks through the streets of Beacon City, heading the Pokémon Center along with his various henchmen wearing masks and armor bearing the symbol of the notorious "Team White Fang." Inside the center, the people who caught the sight of them make sure to step away as to not make trouble lest they want their Pokémon and items stolen or beg for anything else. Their leader heads towards the city's Pokémon Center, a resting place for trainers and their Pokémon.
"Everyone, freeze!" shouted their leader as he enters the center. His henchmen quickly run in and bring their Houndooms to scare other trainers into giving up their Pokémon and items.
"Please, don't hurt us!" pleaded the man. "Take my Pokémon and items!"
"We will if you don't make any trouble to us," said the grunt. "Or you will suffer if you dare."
"Please take mine instead!" said the woman in a begging tone.
"We're begging you! Don't scare us into stealing our Pokémon, please!"
"Of course, we don't want you to get hurt if you obey."
The trainers put their Pokéballs and items into the bags grunts used. The grunts responded by nodding their heads to grab bags to steal items and the Pokéballs of those who begged.
The leader goes up to the nurse in charge behind the desk, hiding behind the counter as to not be seen.
"Excuse me, can I at least get some service here?" asked the leader.
"Please sir, we're just a Pokémon Center!" said the nurse in charge, standing up from hiding behind the counter. "What can you possibly want from us?"
"This center doubles as an orphanage for abandoned Pokémon and those who had been released from their trainers, does it not? I'd like to adopt those Pokémon you have back there, including the item supplies, and along with everyone else's Pokémon here as well. And make it quick! I'm a very busy man!"
"Oh, yes sir! And be right away, sir!"
The nurse rose up from behind the counter, checking the room if there are enough supplies not being stolen and picking her Key Stone without being noticed, and the first thing the White Fang leader noticed was the nurse's long, blonde hair, almost golden in color.
"Wait a second," said the leader indifferently. "You're the nurse?"
"Yes, sir!" said the nurse as she was making her way to the back.
"But do the nurses in almost all centers not usually have pink hair?"
"Well, you see… I'm a very special kind of nurse."
"Hmm, interesting, that's odd…"
Before the leader can finish, the nurse suddenly turned around to face the criminal, wearing her Key Stone from her arm without being noticed. As soon as he got an indifferent yet suspicious look at the nurse's face, he suddenly recognized who she was.
"The kind who always bust criminals like you!" shouted the nurse, ripping off her nurse uniform to reveal her Pokémon Ranger uniform underneath and wearing her Key Stone from her left arm. "Roman Torchwick! You're coming with me!"
"So we meet again, Yang Xiao Long!" said Torchwick. "Sorry, I've got places to be or other work to do. So if you don't mind, I'll just be going now!"
Roman and his men are about to leave until two more rangers showed up at the entrance with their respective Pokémon of their own, blocking their way from going to the exit as their escape plan.
"We can still do this in one of the two ways," said Yang in a warning tone. "A: You give back everyone's Pokémon along with their trainers' supplies willingly, or B: we'll force you to."
"I'll have to go with option C," said Torchwick. "Boys, take her down!"
"As you wish," said the grunts, sending out their Houndours to attack Yang.
"You guys don't learn anything, do you not?" said Yang, sending out her Pokémon. "Go Altaria!"
Yang threw out her Pokéball and called out Altaria, a Dragon- and Flying-type Pokémon capable of having high-pitch soprano voices and clouds as its wings and body.
"What a very cute bird like that," said Torchwick sarcastically. "Boys, attack this cloud-bird!"
The White Fang grunts nodded to their leader and commanded Houndours to attack Yang's Altaria with a Flamethrower.
"I don't think so!" said Yang, using her Key Stone to Mega Evolve Altaria, thanks to the Altarianite.
With Yang pressing the button of her Key Stone to Mega Evolve Altaria, it became Mega Altaria, a Mega Pokémon that has had its body's clouds thickened and its Flying-type replaced with Fairy.
"Use Protect!"
With Yang commanding Altaria, it created a force shield surrounded by a draconic-and-fairy aura that protects it from a Flamethrower used by Houndours.
"Use Hyper Voice!"
After Altaria using Protect from the Flamethrower of the grunts' Houndours, it lets out a high-pitch banshee-like scream that releases indigo-and-light pink rings at them, dealing moderate damage. The grunts covered their ears to prevent their hearing disoriented from Mega Altaria's Hyper Voice, releasing their bags and attempting to retreat!
"That hurts! It's a Mega Pokémon!" said the grunt as all of them returned their Houndours back to their Pokéballs. "What'd we do now, boss?"
"I'll deal with her; retreat until the bullhead arrives," said Torchwick, telling all the grunts to retreat. "This time, it's on!"
Torchwick threw out his Pokéball to call out Krookodile.
"Well, feels I'm facing Pokémon in a Horde Battle," said Yang, taking out her Pokéball to return Altaria. "Oh, well. Celica, let's go!"
Yang threw out her Pokéball and called out her signature Pokémon, a shiny Dragonite she loved to refer by its nickname.
"Celica, Dragon Tail!" commanded Yang.
"Krookodile, Iron Tail!" commanded Torchwick.
Celica's tail glows crimson-and-indigo streaking through it, while Krookodile's tail glows metallic gray and outlined in silver-blue streak. The two clashed each other tail-to-tail, with each trying to overpower each other. Celica went another swing attack against Krookodile, and in this time, Krookodile countered by grabbing Celica's tail with his mouth and began to use his Crunch attack, slamming it side-to-side before the floor. Punishingly taken damage from Krookodile's Crunch attack, Celica flew through the wall with Krookodile punishingly attached from Crunch and slammed its tail, causing Krookodile to let go of his grip.
"Celica, Ice Beam!" commanded Yang. Celica fired a turquoise-light blue beam from its mouth at Krookodile; Krookodile quickly escaped at last second as the beam hit the wall and formed a glacier that could have trapped Krookodile.
"Celica, Dragon Rush!" Celica, surrounded in crimson-and-indigo glow, charged up its strength and tackled down at Krookodile.
"Krookodile, counter it with Foul Play!" commanded Torchwick. As Krookodile is about to be tackled by Celica's Dragon Rush, Krookodile grabbed Celica by arm, lifted her up, and slammed her hard into the ground before punching her several times to the underground.
"CELICA!" shouted Yang, gasping in terror as Torchwick smirked.
Yang and Torchwick watched Krookodile beating Celica with Foul Play followed by a couple of punches. A second later, when Krookodile reaches the underwater bedrock while beating Celica, he beat her several times again with punches, severely damaging her from Krookodile's Foul Play before slamming her to the floor in return, causing the entire center to shake.
"Celica, get up!" yelled Yang bravely. Celica stood up and gave Yang a thumb up. "Use Sky Drop!"
"WHAT!?" said Torchwick.
As Yang commanded Celica to get up from taking punishingly severe blows from Krookodile's Foul Play, Celica wiped her face and began using Sky Drop at Krookodile, causing her body to surround itself in light blue aura and eyes into red. Celica began grabbing Krookodile into the sky, releasing her grip and mauling him with a punch to the face firsthand, and then landed another claw-clenching punch to his jaw, severely mauling him in second. As the attack connects, Krookodile drops down hard to the floor as Celica landed safely. The shockwave from Krookodile's dropping from Celica's Sky Drop was loud enough to shake through the equipment and the back wall that lead to the storage room full of Pokémon. The Pokémon inside quickly scattered away and tried to hide amongst the wreckage to avoid the intense battle. With Celica fatigued after her mauling Krookodile with a Sky Drop from above after heavily taking damage from Foul Play, Krookodile was about to finish her off one last time.
"Finish her off, Krookodile!" Krookodile, in a fatiguing state after receiving an aerial mauling with a Sky Drop, stood up and charged to the back to finish Celica. As Krookodile is about to use Crunch on Celica's head, Celica fired an Ice Beam at Krookodile, sending him back to the center and slowing him down. The ice-cold yet stingy feel of the beam caused severe damage Krookodile, despite being able to stand up the attack and move slow due to his body chilling blue.
"C'mon, you croc, get up!" shouted Torchwick.
"All right Celica, time to send these jokers flying! Use Power-Up Punch to knock them down!" Celica clenched her fist with a crimson-and-orange aura and punched Krookodile, knocking onto Torchwick outside the center. The impact of the punch was strong enough to send Krookodile outside the center at 40 meters away, including Torchwick, with force of knockback. Krookodile went flying along with Torchwick outside the center. Krookodile, receiving a punishingly helpless mauling from Celica's Sky Drop, was no longer in condition to battle, and, apparently, neither was Torchwick. Yang sent out her Mega Altaria from her Pokéball. Celica, Mega Altaria, and Yang walked outside the center to finish the job.
"Could have saved yourself from a lot of trouble you made here, Torchy," said Yang. "Now come quietly before Celica gets mad."
"You don't know who you're talking to?" said Torchwick. Before Yang could respond, a bullhead showed up above as a group of White Fang grunts jumped down, rescuing their fellow grunts from receiving a beating from Yang's Mega Altaria.
"Sir, we… have… to… retreat…" said the grunt, exhausted from being beat by Yang's Mega Altaria.
"Okay, no need to explain. We have to go now."
"What about the bags with stolen items and Pokémon?"
"Forget them. We don't have time for this. We have to leave now."
"Sir, we have to retreat until Torchwick comes here."
"Understood."
As the grunts helped their former members from exhaustion into their bullhead, they were signaled by high-ranking officers inside it for a hasty retreat.
"Bring it on!" responded Yang. "Celica and Mega Altaria can take you all down single-handedly!"
"Perhaps another time," said Torchwick, preparing a hasty retreat while going inside the bullhead. "Boys?"
"Understood," said the grunt, nodding to Torchwick. "Prepare a hasty retreat."
One of the grunts sent out a Skuntank. Celica was about to attack until a Skuntank suddenly sprayed a thick, nauseous, black smoke that caused Mega Altaria, Yang, and Celica to lose sight of them. As soon as the smoke cleared, the White Fang, including the grunts who had their Pokémon received a loud beating from Mega Altaria's Hyper Voice, and Torchwick had already escaped into their bullhead and flew away from the area. Yang sighed disappointedly and kicked the ground in frustration, upset that Torchwick had slipped through her fingers again from his elusive escape.
"Alright Altaria, do your thing," reminded Yang, giving Mega Altaria orders to do. "The bags were left here by the White Fang grunts. Use Agility to get the job done, and then use Steel Wing to carry the bags to the center in order to give them to their respective trainers. Celica and I will handle the situation. Noivern will join you, so he has a keen eye to identify the stolen goods belonged to."
Yang sent out Noivern from her Pokéball and gave him orders to join Mega Altaria for getting the job done. Noivern and Altaria responded Yang with a nod before heading to the center. Yang joined with Celica.
As Noivern and Altaria gave the stolen Pokéballs and items to their trainers from the hands of White Fang grunts, the local authorities soon arrived and arrested the remaining White Fang members in the center. Trainers who fall victim to the grunts thanked in relief, as of recovering and securing items the grunts stole earlier. Yang, along with Celica, went to the back to meet her fellow Rangers Pyrrha and Coco.
"Torchwick escaped again," said Yang. "But overall I think we did very well, especially recovering the stolen items and giving to those who belonged to."
"Agreed," said Pyrrha. "And if you don't count the fact if you nearly wrecked this place."
"Huh? You mean the back wall right there?"
Pyrrha nodded. "Yes."
"We need to make sure everyone's Pokémon is accounted for, and also the stolen items recovered," said Coco. "Yang, you need to go to the back and assess the damage."
"Why me?" groaned Yang.
"Because you caused it in the first place!" responded Coco, showing evidence recorded via security camera about the fight in the back wall earlier from her scroll's "Surveillance" app.
Yang sighed and went to the back, checking any damage from the area.
Yang took out her scroll and quickly scanned all the Pokéballs in the deck. As Altaria and Noivern kept busy from their duties, Celica began to clear out the wreckage and gather all the loose Pokémon out of the center. Yang noticed something hiding in a dark corner. Curious about what was over there; she went to the corner to find out. She shone her scroll from the "Flashlight" app and noticed an Eevee balled up in the corner, with its eyes closed and body shaking in a rattling motion.
"Hey there, little fella, don't be scared," said Yang in a caring tone. "I'm a nice trainer. Come here."
The Eevee did not respond as Yang reached to grab it; the Eevee already moved back but was already in the corner. Yang picked up Eevee and gave it a caring yet reassuring hug. The Eevee stopped shaking from its body with its eyes closed, not fully trusting Yang just yet. Yang took out her scroll and opened its scanned app, and according to the scroll, the info says Eevee is one of the abandoned Pokémon that had no original trainer.
"No trainer, huh? Guess it's time for adoption. How'd you like to hang out with me for a while?"
"Yang!" shouted Coco, signaling Yang with a hand-raising gesture. "Hurry up already!"
"Yeah, yeah, I hear ya."
As the rangers were going over the damage caused in the fight earlier, on a rooftop across the center is a trainer dressed in black and has orange thermal goggles. She had followed the White Fang to the center and was about to intervene until the rangers appeared at times. She stayed as she watched the entire incident go down, and now it was over, she disappeared into the darkness and ran out of sight.
Beacon City Cafeteria: 10:25pm.
After the rangers had done assessing and cleaning up the mess in the back wall, they sat down from their respective chairs in the cafeteria area as they took rest for an hour. Coco glanced at Yang's Key Stone.
"Yang, what's with the Mega Stone?" asked Coco, checking at Yang's Key Stone.
"It's an "Altarianite," responded Yang. "My uncle gave it to me since I passed the Ranger test."
"So, it's true," said Pyrrha. "You mean Uncle Qrow?"
"Yes. He gave me the Key Stone, in which is called "Mega Gauntlet."
"A Key Stone version of "Ember Celica" with a "Mega Evolve" feature," said Coco. "I see. Mine is the "Mega Shades," which automatically triggers Mega Evolution."
"Mine will be the "Mega Collar," said Pyrrha. "When I arrived in the Vale region, I passed the Ranger exam. And the professor gave me this. It automatically triggers Mega Evolution."
Coco and Yang responded by nodding their heads to Pyrrha for agreement.
"Alright, before we begin," reminded Coco. "Let's head back."
"Right!" said Pyrrha and Yang to Coco as all three headed back to the exit.
