Ruby blinked, surprised by the strange creature's appearance. During the moment of silence, Mawile let herself out of her Pokeball to see what was going on.

"Huh..." Ruby said simply. "Well... Not the weirdest thing I've seen, but it's up there."

"Ngngngngng!" The creature chirped.

"What the hell could be weirder then that!?" Gladion asked. Ruby proceeded to pull out a picture and held it up so he could see. "Oh dear Arceus!" Gladion covered his eyes. "Why the hell do you carry that with you!?"

"Just in case people ask that question." Ruby turned her attention back to the creature, who appeared to flicker for a moment, before suddenly appearing closer to Ruby, staring at her curiously.

"Ni-Lego?" The creature chirped. Ruby stepped up to it.

"Don't!" Gladion said sharply. "That thing's dangerous!"

"Doesn't seem dangerous." Ruby responded.

"That thing is a parasite! It's extremely dangerous!"

"And how do you know this?" Ruby retorted. Gladion remained silent. Suddenly, there was another flash from the portal above them, and the creature swooped behind Ruby, as if for protection. It made a noise of fear. Something else burst through the portal, landing on the ground in a crouch. It stood up, revealing itself in its' entirety. It appeared to be a cross between a human female and a cockroach. It was mostly white, and stared at them with purple eyes. It surveyed the group quietly, before spotting the first creature cowering behind Ruby.

"Phero-MO!" Its' shriek was unearthly as it lunged with blinding speed. Gladion barely pulled Ruby out of the way, allowing the new creature to slam into the first one, sending it flying into a nearby wall.

"What the hell!?" Ruby asked, watching the new creature brutally attack the first one. she ran up to them, not caring for her own safety. "Hey! Bug lady!" She shouted, catching the new creature's attention. "The fuck's your problem!?" The new creature swiped her hand, sending a silver colored wind at Ruby. Mawile leapt in front, intercepting the attack with a Fire Blast. Gladion ran up to them.

"Stop!" He hissed. "That thing is an Ultra Beast! It's highly dangerous."

"I don't even know what an Ultra Beast is!" Ruby retorted. She reached toward the locket around her neck. It popped open to reveal a Keystone. It suddenly began to react with a Mega Stone hidden in Mawile's second mouth. Mawile began to glow intensely. When the light faded, she had double in size, with long extensions flowing from her head and a second set of jaws appearing alongside the first. "Let's see how strong this thing is."

Ash followed Anabel quickly. That portal appearing wasn't exactly easy to miss. She stooped, staring up at the Ultra Wormhole.

"It's still open! We have to find a way to close it before any Ultra Beasts get through!" There was a bang, then a strong, humanoid cockroach flew into a nearby wall.

"Might be a little late on that." Ash said. Anabele frowned.

"UB-02..."

"Huh?"

"The International Police refers to the Ultra Beasts by code names. That one is referred to as UB-02: Beauty. If you don't want to get technical though, its real name is Pheromosa." Right after she finished her sentence, something else appeared, and Pheromosa recovered enough to fight. "A Mega Mawile?" Anabel asked, confused by the shiny's sudden appearance.

"That's Ruby's Mawile! The hell is she thinking!?" Ash asked. Pheromosa Lunged at Mawile, only to be countered by a Power-Up Punch to the jaw.

"Of course, When Mawile Mega Evolves, its' ability becomes Huge Power, which doubles its' attack power and makes it a truly dangerous opponent, especially with moves like Power-Up Punch. She watched as Pheromosa hit Mawile with a Triple Kick, only for the Deciever Pokemon to grab her leg with a Thunder Fang and throw the Ultra Beast into a nearby wall, needless to say, they Glacies locals had pretty much noticed this and were ducking for cover. Anabel looked at her device. "I'm getting energy reading of another Ultra Beast nearby." She took off, Ash shrugging before following. Anabel's thoughts were going wild. If there were Ultra Beasts here, then what the hell were the Island Guardians doing!?

"Dammit give back my muffins!" Lele snapped, chasing the Nebula Pokémon around the rooftop.

"Uh... Will that be all Mr..."

"Koko..." The Pokémon chirped. The cashier blinked, before ringing up the items.

Tapu Fini was still looking at Gladion through binoculars.

Meanwhile, on Alola's Ula'Ula Island, Tapu Bulu was lazing around in his temple, snoring loudly, a couple dozen unopened Malasada boxes nearby. A man in a police uniform with grey hair and red eyes stood nearby, watching the sad display, shaking his head in disbelief while an Umbreon stood near him, watching quietly.

Mawile intercepted Pheromosa's Silver Wind with another Fire Blast, before moving in and Power-Up Punching the Ultra Beast in the abdomen, sending her flying into a lamp post and only making her angrier. The Beast flew at Mawile as a blur, attempting a Triple Kick, only to be hit in the face with a Flash Cannon. Pheromosa let out an angry shriek, Lunging at the Deciever Pokémon once again. Mawile grabbed the Bug and Fighting type by the shoulders, spinning in the air and using the momentum to throw the Ultra Beast into another lamp post. The Ultra Beast stood up shakily, her legs wobbling. She glared at Mawile before her form began to flicker. Then, she vanished completely. Panting, Mawile reverted to her normal form and began to walk back to where Ruby was...

"Ngngngniii!" The strange Ultra Beast chriped as Mawile reappeared on the battlefield.

"You okay?" Ruby asked, and Mawile nodded.

"Lego! Lego!" The Ultra Beast chirped, appearing inches from Ruby's face. The Ultra Beast stared at her, as if inspecting her. The Beast began to flicker, vanishing just as the Wormhole finally closed above them.

"Oh my!" A new voice spoke. Ruby, Gladion , and their Pokémon turned to see Ash and Anabel running up to them. "That was UB-01!" Anabel breathed. She noted Ruby's confused face. "If you don't want to get technical, you can call it Nihilego."

"You wanna explained to me what just happened." Ruby retorted. During this time, Gladion silently recalled Null and walked away.

Meanwhile, Faba observed the spectacle from a nearby restaurant, a gleeful smile on his face. Nihilego was now loose in the Glacies Region. Oh how President Lusamine would be so pleased with this information.
