Battle Royal Dome (Night)

"We have a first since the Battle Royal Dome opened it's doors!" the announcer said as four people made their way to the arena. "19 consecutive victories, it's the Mountain King and Mimikyu! Will they make it 20 with this Battle Royal?"

The duo the announcer was referring to was standing in the Red Corner. The trainer was a teenage blonde boy wearing a Legendary R-D Hoodie, a white undershirt, black pants, and red loafers. On his wrist, he wore a Z-Power Ring. And on his hand, a Mega Glove. The Pokemon in question was a small, black creature wearing a Pikachu-like rag. Hearing the audience cheer for them, both the boy and his Mimikyu took a bow. Their opponents were a Magneton, a Sableye, and a Barbaracle.

Once the opening bell sounded, the battle began.

"Sableye, use Sucker Punch on Mimikyu!" Hearing it's trainer's command, the Darkness Pokemon dashed to Mimikyu before striking with one of it's claws. Of course, thanks to Disguise, it was severely weakened. Mimikyu's eyes then sparkled, frightening Sableye and making it return to it's original position on the ring.

"Magneton, use Flash Cannon on Mimikyu!" Gathering light energy in it's center, Magneton released a beam of energy at it's target.

"Barbaracle, Poison Jab on Mimikyu!" Covering it's arm in poison, Barbaracle ran toward the small Pokemon.

Both attacks landed, but neither did much damage to Mimikyu. "Despite appearances, Mimikyu is incredibly tough! It's completely unfazed by it's opponents' attacks!" the announcer said, leaving the Diguise Pokemon's adversaries in shock.

"Mimikyu, it's our turn!" the Mountain King said to his partner, who chittered in excitement. After placing a Firium Z in his Z-Power Ring, the boy performed a series of poses alongside his Pokemon. Then, red energy surged from him to Mimikyu, enveloping it in his Aura. "Now, use Inferno Overdrive!"

The Ghost/Fairy Type gathered all of it's flame power in front of it, creating a massive fireball. It then struck it with it's claws, sending it flying at it's opponents. Once it made contact with Magneton, it detonated and covered the entire ring in fire. When the smoke cleared, Barbaracle, Magneton, and Sableye were all knocked out.

"There it is! The Mountain King's 20th victory in a row!" the announcer said as Mimikyu jumped into it's Trainer's arms, squeaking in happiness.

Suddenly, a power surge caused the lights in the arena to shut off. In the center of the ring, a tear in space appeared. Frightened, the audience fled the stands. Even the announcer ran away in terror. They had all seen what had happened when Dusk Mane Necrozma opened Ultra Wormholes across Alola, so they wanted to be as far away from it as possible.

'Why would an Ultra Wormhole appear here?' the boy thought to himself as Mimikyu hissed at the spacial anomaly. Before he could call back his Pokemon, the wormhole exploded, drenching the room in blinding light. When the light died down, both the Mountain King and his Mimikyu were gone.

Kuoh Forest (Night)

After a few minutes, Mimikyu woke up in a daze. Once it saw where it was, it immediately began searching for it's Trainer. Thankfully, the boy was very easy to spot in the dark due to the fact that he was on fire. Somehow, this blaze was contained to his body and didn't burn anything else.

The Disguise Pokemon breathed a sigh of relief that it found it's Trainer so quickly. And more importantly, that it was the first one to do so. If the monarch was found by any passing humans, they likely would've tried to put out the fire, which was deadly for an Elemental like him.

As Mimikyu approached, it noticed something odd with the King's figure. It squinted and was able to make out two odd lumps on his chest. It's eyes widened in shock when it realized what had happened. Using Burning Jealousy, it attacked the Trainer to wake him up. Once the crimson flames made contact, he awoke.

"Ow! What the heck was that for?" he asked, noticing something off with his voice. "Did Sans put helium in my soup again?" he pondered, sounding out various words with this new voice. Hearing his partner chittering, he turned to the Pokemon. It had a nervous expression (somehow) as it pointed at his chest. Looking down, the boy, or rather, the girl, had one thing to say. "Sheep." she blanched as she stood up, using a mirage to see what she now looked like.

Her outfit hadn't changed at all, though her new 'assets' made her shirt tighter than before. She'd need to rectify that before any combat. She sent Mimikyu back into it's Poke Ball before taking off her jacket and shirt, leaving her half-naked. She then conjured flames from nowhere, forming a katana made from pure Traptanium. Bracing herself, she cut into her own flesh and tore off her 'unwanted additions'. The two slabs of meat and stone fell to the ground, crumbling into dust when they were no longer a part of their owner's body. The wounds left behind by this act did not leak blood, but magma. After a few minutes of healing, the Trainer put her shirt and jacket back on.

'It's probably best if the rest of my Pokemon saw me like this so they won't be caught off-guard during battle.' she thought to herself as she got out six Poke Balls, including Mimikyu's. She threw them into the air, releasing her team. "So, what do you all think of my new look?" she asked, nervous of what her friends would think. In almost no time at all, she was pulled into a deep hug by all six of her Pokemon. "Thanks, guys." she said with a smile as she closed her eyes. She lost track of how long she stayed like that.

After recalling her team back to their Poke Balls, a buzzing noise sounded from the Trainer's jacket pocket. Recognizing the sound, she reached in and pulled out an oddly-shaped white phone. On it's screen read a simple message.

"Enroll in Kuoh."
