Author's Notes 1:

Yay we finally get to the main event, Nanu vs Grimsley! This battle I've been wanting to write for seven years, would've done this sooner if it weren't for Fire Emblem brainrot lol. Anyways, so when I did the first draft of the battle it, um, went about 12-13K words. D= Because of that, the battle will be split into two chapters.

Another thing! For this battle I experimented a bit with format and writing style similar to what Taurus Versant did for Hau and Moon's battle in Eldritch. That's probably why the battle's wordcount went bigger than expected LMAO. Besides that, I have the battle switch between Nanu and Grimsley's POVs, which you'll be able to tell easily with the NANU and GRIMLSEY headers there.

Lastly, I made a quick VS banner for this special occasion. = P Man it's been a while since I've done this type of graphic art lol.

I think that's about it! Now onto Part One of the battle!

Chapter Thirty-Four

Foul Play (Part One)

Nanu trained with Anabel all afternoon up until sunset. Tapu Bulu and Raikou didn't hold back and used their full strength. Anabel gave her commands with great confidence, fitting for an Interpol chief. Once they finished with their training, Anabel and Looker needed to contact headquarters before they would return to the Pokémon Center.

As it was starting to get dark now, the kahuna decided to head to the Pokémon Center. He stepped inside to see some trainers and Pokémon in the lobby. Nanu spotted Grimsley, Acerola, and Molayne at the corner talking to each other. Once he approached them, Acerola and Molayne beamed at him while an indifferent expression crossed Grimsley's face.

"Oh, hi Uncle Nanu!" Acerola greeted him. "Were you checking to ensure everyone in this village has returned safely?"

"I did earlier and it looks like everyone made it back here fine." Nanu then remembered how Grimsley had left to find Dulse and Colress, so he asked him, "Did you get to speak with Dulse and Colress?"

Grimsley gave him a blank stare at first, only for a small smile to tug at the corner of his lips. "I have. They mostly informed me of their research on Necrozma. When it fuses with either Lunala or Solgaleo, it can control their mind and goes into a frenzy with all the light it's consuming."

"Ah, that makes sense!" Acerola gave an understanding nod and faced Nanu. "Before you came here, Grimsley had been training for his upcoming battle with you. Molayne's been helping him, too!"

"It's true," Molayne said. "Grimsley and I went to check out some of the Bisharp over at Route 17 and trained over there."

"Not only that, but we found a Kingambit over there," Grimsley said, a proud smile curling into his lips. "Queen went against him and emerged victorious."

"You were able to defeat a Kingambit?" Nanu said in an astonished tone, raising a suspicious brow. There wasn't all that many Kingambit running around in Alola as only the strongest Bisharp was able to evolve into that Pokémon. At one point during his time in Interpol he considered training a Pawinard, but decided against it due to how reckless that line of Pokémon could be. He already learned to not underestimate Grimsley after seeing his Pokémon fight against Guzma and Glutton. He snorted and shook his head. "That shouldn't be surprising with you being Unova's Elite Four."

"It wasn't an easy fight and another Bisharp helped the Kingambit out. I was amazed at that Kingambit's strength and stamina."

"Wow, no wonder you're an Elite Four trainer!" Acerola's beaming smile grew wider, and she turned to Nanu. "How about you, Uncle Nanu? Started some training of your own?"

"I have, actually. I just finished some training with Anabel before she and Looker needed to report to headquarters."

"Oh, what kind of training?" Acerola asked in an eager voice.

"I'm keeping that a secret."

Acerola hung her head down and said in a disappointed voice, "Aw, no fair!"

"Either way, that sounds fun." A small smile formed on Molayne's lips, and he faced Grimsley. "Looks like Kahuna Nanu is just as serious about that Pokémon battle as you."

Nanu crossed his arms and grunted, though there was no denying that he was indeed serious about his upcoming Pokémon battle with Grimsley. He was once again reminded that the aloof, gambling-loving man was part of the Elite Four, and speaking of which...

"Hey, Acerola."

Acerola's face perked up. "Yes, Uncle Nanu?"

For some reason, Nanu's chest fluttered, and the back of his ears warmed up. He was never good at being sentimental. While speaking, he scratched his cheek.

"Well, Professor Kukui has been nagging me to choose a perfect candidate for the Elite Four after turning down that offer from him. After some thought, I decided that you would be the perfect candidate for the job."

Acerola's eyes flew wide and she gasped with her hand near her mouth. After letting that news sink in, she squealed in delight and flung her arms around Nanu for a tight embrace.

"Oh my gosh, thank you thank you thank you!" She let go of him, offering him her brightest smile ever. "I'll be sure to take this position seriously!"

"Congratulations Acerola, I'm sure you'll do wonderfully," Grimsley said, smiling.

Molayne chuckled and grinned. "Looks like we'll be working partners then." He asked Nanu, "Did you let Kukui know yet?"

"Not yet. I'll tell him the news tomorrow."

"Does that mean I'll start my Elite Four duties once you do that?" Acerola asked.

"I'm certain that Kukui will start you as soon as possible." Nanu smiled a little at Acerola's excitement at being an Elite Four trainer now. She still had a long way at being Grimsley's level, but she was young and no doubt would catch up in no time. Choosing her as Alola's Elite Four made him look forward to his battle with Grimsley even more.

The day before his upcoming match with Nanu, Grimsley trained all day with Molayne. Mars was the perfect battling partner for Queen-their skills were on equal footing and they didn't let their guard down. Molayne even gave a few tips as a steel-type specialist on how to take advantage of Queen's steel-typing side. When they were done with training late into the evening, Grimsley was confident that he would have the upper hand in their battle.

On the morning of Grimsley's match with Nanu, Gladion, Dulse, and Colress had to leave for Aether Paradise while Looker and Anabel were needed back at Interpol Headquarters. Kukui had joined with everyone else outside of Tapu Village to say their goodbyes. There were two helicopters parked outside, one from Aether's Paradise and another from Interpol.

"I'm a bit saddened that the chief and I have to report back to Interpol Headquarters," Looker spoke with a sad smile. "I was immensely enjoying the Alolan sunshine once again."

"Same here," Anabel said with a small smile. She faced the group and added, "It was a pleasure seeing you again, Officer Nanu, and meeting with everyone else here."

"I'm glad to have met the both of you," Grimsley said with a smile on his own.

A crooked smile was pulled on the corner of Nanu's lips, and he had one hand placed on his side. "The next time you two visit I'll make sure to have malasadas ready."

Looker chuckled and grinned. "I look forward to that, then! The chief and I will also keep you updated on the changes concerning the Ultra Task Force."

"If you guys need some help with that in any way, let me know."

"We will," Anabel said, offering him a reassuring nod.

Both agents took turns embracing Nanu. They waved everyone goodbye and stepped inside their helicopter. Grimsley watched as the helicopter lifted itself and took to the skies. He flinched when someone tapped on his shoulder, and a lump formed inside his throat upon seeing Colress in front of him.

"I guess this is goodbye for real," Colress said, wearing a slacked expression on his face.

"I believed so." A heavy feeling settled inside Grimsley's chest, and he released a deep sigh. "To think we would be reunited in this region under strange circumstances."

"I agree with that assessment," Colress said with a soft chuckle. His lips changed to a slight frown. "I didn't forget what you said to me back at Poni Island, that we can't go back as friends. Do you still think that?"

Grimsley's chest tightened the instant Colress said that. He wondered the same thing after their conversation outside the abandoned Thrifty Mart a few days ago. His feelings towards Colress now were complicated, though maybe there could be a middle ground.

"A part of me still thinks so. However, I can see that you're trying to make up for your involvement with Team Plasma." He offered Colress a small smile. "Perhaps someday we can catch up over coffee as acquaintances."

Taken aback by his response, Colress gasped and had his fingers close to his lips. His face brightened.

"That sounds nice, I would like that very much." Colress pulled out a blank business card and pen from his heavy jacket. He wrote down several numbers on the back and handed it to Grimsley. "Here's my number if you ever want to talk again."

After staring at the card for several seconds, Grimsley gave a low hum and put the card away inside his bag. "I'll keep that in mind."

Both men made quick gazes at each other and shook hands. Grimsley's pulse quickened at the contact of their skin and how warm his palm was. He turned around to see Gladion speaking with Lillie and Selene, catching some of their conversation.

"I called Wicke this morning. She told me that Mother and Guzma still need some rest but are doing much better."

"That's great to hear!" Lillie said and smiled in relief. "I'll be sure to visit Mother very soon."

"Why don't we do that tomorrow after Grimsley and Nanu's battle?" Selene suggested. "I can hold off my trial at Poni Island a little while longer."

Lillie's smile widened. "Oh, I would appreciate you being by my side when I visit Mother!"

Smiling a little, Grimsley recalled asking Lillie and Gladion what happened with their mother last night. Lillie told him that Colress had contacted Wicke and she and a few employees helped take Lusamine and Guzma back to Aether Paradise. They rested there, recovering from their ordeal with Necrozma.

Selene and Lillie each gave Gladion a warm embrace which he gladly returned. Right after, he joined Dulse and Colress as they stepped inside the helicopter together. Like with Anabel and Looker earlier, Grimsley gazed up as the helicopter took flight. Musing that this might not be the last time he would see Colress, Grimsley's chest fluttered.

"I'll be heading back to Poni Island," Mina said. "I need to return Buttercup to Hapu and prepare for your Poni Island trials, Selene."

"I can't wait to get started with your trials!" Selene said, beaming.

Mina smiled back and faced Nanu and Grimsley. "Wish the both of you good luck on your battle! I'm sure it'll be a rad one."

Nanu snorted while a small smirk tugged on the corner of Grimsley's lips.

"I appreciate the well wishes there," Grimsley said.

"Tell Hapu that we all said hi!" Acerola said, a grin stretching across her features.

"I'll make sure to do that," Mina said, smiling back. She pulled out a pokéball and released Buttercup, Hapu's Flygon. Mina hopped on Buttercup's back and glanced over her shoulder. "I'll see you guys soon!"

After waving everyone goodbye, Mina turned back to Buttercup and told her to go to Poni Island. The Flygon screeched, flapped her wings, and they flew off into the horizon. Grimsley gazed up at the skies for a brief moment until Acerola spoke.

"Hey Uncle Nanu, do you know where Tapu Bulu is? I don't see them anywhere today."

"Ah, the big guy left for Lake of the Moone earlier this morning. We'll meet up with them here."

Grimsley swallowed hard, remembering that Tapu Bulu would be one of the Pokémon Nanu would use in their battle. He saw the Alolan guardian's strength firsthand and knew not to underestimate them.

"Since we'll need to travel a bit to get to Lake of the Moone, should I prepare some PokéRides for us?" Molayne asked.

Selene's face lit up and she suggested, "Actually, why don't we have Nebby teleport us there like they did to us a few days ago? It'll be much faster!"

With a raised brow, Nanu asked, "I wouldn't mind us getting there now, but where is Solagelo? Are they even still around here?"

As if right on cue, a sound that resembled crackling thunder was heard. A small ultra wormhole appeared, and Nebby shot out from it. They let out a mighty roar before landing on the ground. Everyone but Selene gave startled stares at the legendary that just appeared.

"Guess Nebby knew that we would need them to take us to our destination!" Selene said as a grin stretched across her features. Next to her, Nanu sighed and rolled his eyes.

"I believe so!" Kukui said with a laugh. Facing Nebby, he asked, "Say Nebby, do you think you can teleport us to Lake of the Moone?"

Already Nebby made a low growl and nodded, as if understanding Kukui's request. The professor responded with a satisfied grin and pumped his fist into the air.

"Alright, woo! Okay everyone, get ready!"

Everyone gathered around Nebby and waited a few moments until the Sunne Pokémon let out a second mighty roar. The last time Nebby teleported them a few days ago, Grimsley wasn't prepared for that and felt lightheaded for several seconds after. A warm sensation surged all over his body, and all of Tapu Village disappeared in front of his eyes.

The instant Grimsley and everyone made it to the Lake of the Moone, his mind spun around like a carousel. It was some seconds before he wasn't feeling dizzy anymore and gazed around his surroundings. Nebby had teleported them to the front of the Lake of the Moone. The shimmering lake, the compass roses, and the shrine up ahead were familiar to him. The last time Grimsley was here, he overheard Colress's conversation with the Ultra Recon Squad and laid his eyes on Lunala. And now this was where his battle with Nanu would commence.

Up ahead, Tapu Bulu floated above the lake. Selene pointed to where they were and shouted cheerfully for everyone to see. When Tapu Bulu noticed everyone, they made a greeting sound and floated to Nanu's side.

"Oh wow, so this is the Lake of the Moone?" Selene asked as she gazed around in awe.

Acerola beamed and clapped her hands. "Yup! Legends say that this lake has connections to the legendary Pokémon, Lunala! Oh, the lake is extra beautiful today!"

"The lake is indeed beautiful and makes for a great backdrop for this battle," Grimsley said, smiling in agreement. He already thought about how he would have Blackjack use the lake to his advantage. He faced Nanu and Tapu Bulu. "Shall we get started with our battle, then?"

"I'm ready," Nanu said in his usual indifferent tone, though there was some hint of excitement that Grimsley picked up for the first time. Nanu turned towards the Alolan guardian and asked them, "How about you, Tapu Bulu?"

"Bulu!" Tapu Bulu shouted and gave an enthusiastic nod. Nanu snorted and faced back at Grimsley.

"Tapu Bulu can't wait either," Nanu said, this time a small smirk pulling on the corner of his lips. Grimsley grinned in return, the adrenaline inside his blood already kicking in.

"Awesome that you two are ready!" Kukui said with a bright face. "This will be a Supercell Slam-ing great time, woo!"

"Does that mean you'll be refereeing this match, Professor Kukui?" Lillie asked.

"Sure, I can do that!" The grin on Kukui's face widened, and he faced Nanu and Grimsley. "Alright men, into your positions!"

Both men went to their positions, Grimsley on the left while Nanu went to the right. Tapu Bulu floated to Nanu's side. Kukui took a few steps forward in front of the men as the referee for the match. Everyone else including Nebby stayed on the sidelines.

"So today we will witness an exciting battle between two strong dark-type specialists!" Kukui began in a booming voice. "It will be a 5-on-5 Pokémon match, switching allowed. Nanu, Grimlsey, your first Pokémon, please!"

Both men pulled out their pokéballs and released their Pokémon. Grimsley chose Queen, now a Kingambit, while Nanu let out his Absol. Queen's red armor gleamed under the sunlight.

By the stunned look on Nanu's face, it seemed he didn't expect Queen to evolve. Lillie and Selene also let out shocked gasps while Acerola beamed and Molayne gave a knowing smile.

This was the battle Grimsley made the biggest bet on himself to win.

Nanu's face fell the moment Grimsley released Queen. He only saw a handful of Kingambit around Po Town, and Molayne had informed him that Mars evolved into one recently–he already expected him to have one before starting his gig as Alola's Elite Four. It shouldn't have surprised him Grimsley would do the same.

"Hey, what's that Pokémon?" Selene asked.

"That's a Kingambit, a Pokémon that Bisharp could evolve into," Nanu answered the girl's question. He turned his attention to Grimsley, a small smile pulling on the corner of his lips. "Congratulations on evolving your Pokémon, vampire boy."

The side of Grimsley's lips twitched, only for him to regain his composure and chuckle. "Why thank you. I already mentioned how Queen and I have been training, and this is the result of it."

"I can see that." With a warning stare, Nanu said, "However, don't think that act alone will win you that match."

"Oh, I'm aware of that." A grin stretched across Grimsley's face, and he pulled out a silver coin. For a second, Nanu thought he saw a flash of fangs on him. "Before we start, how about we let fate decide who gets the first move? I'll let you choose."

Nanu pressed his lips and furrowed his brow. Of course, he would suggest that. Fine, he would play Grimsley's game for once.

"Tails."

Grimsley smiled in satisfaction and tossed the coin in the air. There was a gleam from the coin, and he caught it with his right hand. He opened his hand to reveal it landed on heads.

"My, oh my, looks like I'll make the first move."

Nanu responded with a grunt. That was fine, he should be able to counter whatever trick Grimsley would immediately pull.

"Alright, so Grimsley will make the first move, yeah!" Kukui declared. He raised his arm to the sky. "The battle between Ula'ula Island's Kahuna Nanu, and Unova's Elite Four Grimsley, begin!"

Kukui put his arm down, signaling for the two trainers to start.

Grimsley made the first command. "Let's start strong with X-Scissor!"

"Keep countering it with Night Slash!"

Queen crossed her arms and infused her blades with bug-type energy while Absol howled and the scythe on his forehead glowed dark purple. Both Pokémon raced toward each other and their weapons collided in fiery sparks. They exchanged several blows, predicting each other's moves and keeping the pressure up.

Nanu decided to change things up and called for Absol to use Sucker Punch, his paw glowing dark-type energy. Grimsley told Queen to do the same, her right fist releasing the same dark-type energy. When their attacks connected, a small explosion occurred that pushed both Pokemon backwards and apart.

"Now use Shadow Claw!" Nanu ordered. A burst of shadows that resembled a claw swirled around Absol's paw, and he rushed forward.

"Throw Absol off with Kowtow Cleave!"

Upon hearing that move from Grimsley, Nanu's blood ran cold. He was aware of what Kingambit's signature move could do, so he needed to warn Absol quickly.

"Keep moving and push back the best you can!"

Queen crouched down and bowed, waiting for Absol to stop in his tracks. Fortunately, Absol picked up Nanu's warning and continued to move towards the Kingambit. Grimsley's Pokémon had no choice but to jump off the ground and launch at Absol. Absol raised his Shadow Claw in preparation, only for Queen's Kowtow Cleave to land a hit and leave a deep cut on his leg. The Disaster Pokémon growled in pain and glared at Queen.

Not liking how this battle was already in Grimsley's favor, Nanu narrowed his eyes and his fingers twitched. It was still the beginning of the battle, though, so anything could happen after this.

"I'm impressed that your Kingambit already mastered Kowtow Cleave. However, don't get cocky yet."

A calm demeanor washed over Grimsley's face. "Oh, I know that. I'm only just getting started."

"Same here." After saying that, Nanu thought of exploiting Queen's ground weakness and wanted Krookodile to take over. "You take a breather, Absol."

After Nanu returned his Pokémon, he brought out Krookodile's pokéball and released him. The Intimidation Pokémon stomped his feet on the ground and roared

Grimsley made a "hmph" sound, as if expecting his strategy. He too pulled out Queen's pokéball. "That's enough for now Queen, good work!"

He returned Queen and switched to another pokéball. This time he released Blackjack his Sharpedo, who swam around the lake wildly the second he touched the waters. Nanu was already aware Krookodile was at a type disadvantage, but he didn't move his hand to his other pokéballs and let his Pokémon stay.

"A Krookodile against a Sharpedo?" Selene asked with a confused stare.

"I've seen Uncle Nanu's Krookodile go against water-type Pokémon before," Acerola said, offering a confident smile. "I think he knows what he's doing!"

Grimsley ordered Blackjack to use Aqua Jet, as the Brutal Pokémon swum at a breakneck pace. Speed Boost was a very rare ability for Sharpedo, so Nanu was sure Grimsley's Pokémon had Rough Skin instead. Krookodile would get hurt, but he already thought of a plan to switch out the shark Pokémon early.

"Grab that Sharpedo with your jaws and use Thunder Fang!"

Krookodile opened his jaws wide, which cackled electric sparks. The second Blackjack slammed into Krookodile's body, he sank his teeth deep into the other Pokémon's skin, and electricity coursed through him. That caused Blackjack to growl in pain and pull away. Krookodile stumbled backward a few steps and screamed, recoiling from Blackjack's Rough Skin.

Lillie gasped in shock and asked, "Wait, so Nanu had Krookodile use a physical attack despite him potentially getting hurt by Blackjack's Rough Skin?"

Kukui crossed his arms and hummed. "Krookodile using Thunder Fang lets him land a super effective hit on Blackjack!"

Flashing Nanu a grin, Grimsley said in a cool tone, "I already figured that you would take that gamble, but I still have the upper hand. Blackjack, go for Poison Jab this time!"

The fin on Blackjack's back shimmered purple, and he swam vigorously once more. A small smirk tugged on the corner of Nanu's mouth. Time to set his plan in motion.

"Wait until the Sharpedo gets closer."

Krookodile glanced over his shoulder at his trainer and snarled in understanding. As soon as Blackjack got close to the shore, Nanu called out, "Now use Dragon Tail!"

Krookodile's tail shined green draconic energy, and he slammed it onto Blackjack's forehead. At that instant, Blackjack turned into a red beam of light and returned to his pokéball. Like before, Krookdile recoiled from Blackjack's Rough Skin but quickly recovered and snarled.

Nanu felt bad for making Krookdile hurt like that the second time, but he knew that his Pokémon trusted him and was willing to take the hit. He glanced at Tapu Bulu, who had been floating close by his side and watching the battle with thoughtful eyes. He and his Pokémon were making good progress, but there was still a long way to go.

GRIMSLEY

Taken aback by what just happened, Grimsley swallowed hard and furrowed his brow. He could use this to his advantage, though, so a smug smile spread across his face and he tugged at his scarf.

"I should've expected that you would play just as dirty as me. Well, I'll make do."

The first few days of Grimsley's visit in Alola, it took him some time before he warmed up to the region and enjoyed its relaxed pace compared to Unova's hustle and bustle. He did his first battle with a young trainer who used an Oricorio and saved Roland from being harassed by two Team Skull grunts. Soon after, he saw an Ultra Wormhole for the first time.

Grimsley pulled out another pokéball and this time let Dice his Scrafty out. The Hoodlum Pokémon pulled his skin above his waist and held his chin high. When Grimsley called for him to use Ice Punch, his fist became covered in cold energy and he rushed towards Krookodile.

Nanu immediately commanded Krookodile to counter with Aerial Ace, which he did by launching into the air and slamming into Dice before he could get a hit in. Grimsley asked Dice to try Ice Punch once more, and Dice's fist was shrouded with ice energy. He hoped that his Pokémon's move would succeed this time.

Before Nanu could order another move, Dice landed an uppercut punch below Krookodile's snout and made him back away several steps. Small shards of ice popped where Dice had hit Krookodile, though he quickly shook those off and glared at his opponent.

Nanu's eyes grew wide and he flinched at Dice's sudden attack. His face slipped back to his usual stern expression and called for Krookodile to use Earthquake. When Grimsley ordered Dice to launch himself in the air, he did just that with his strong legs and avoided the powerful ground move. Grimsley was sure though Nanu would come up with a perfect retaliation for that.

"Grab that Scrafty's leg with your jaws, Krookie!"

Before Dice came in contact with Krookodile, the crocodile Pokémon snapped his jaws on Dice's leg and caused him to scream. Krookodile followed that up by slamming him on the ground. Dice picked himself back up quickly but took deep breaths.

An odd noise left Grimsley's throat, and he made a "hmph" sound. That was fine, he could bounce right back quickly.

After meeting with Nanu's son, Iokua, Grimsley desired to have a battle with Ula'ula Island's Kahuna Nanu. When he got to meet with Nanu and Acerola at the Aether House, he held that desire off for now and instead forced the kahuna to take him to the Ruins of Abundance. The next morning, he, Nanu, and Acerola first took a small detour at the abandoned Thrifty Megamart, where they met with Colress and the Ultra Recon Squad.

He pushed those unsettled feelings towards Colress aside, and later that night Grimsley knew more about Nanu's past as a former International Police agent. The group then made their way into the Ruins of Abundance, and there Grimsley witnessed Nanu being blessed by Tapu Bulu's light.

"Way to go, Uncle Nanu!" Acerola cheered and pumped her fist in the air. Next to her Lillie and Selene let out astonished gasps while Kukui and Molayne wore serious expressions. Both Nebby and Tapu Bulu also watched with great interest.

Nanu urged his Pokémon to follow that up with Thunder Fang. Krookodile opened his jaws, electric currents coursing through his sharp teeth, and charged at Dice.

Already a plan formed inside Grimsley's head. He tugged at his scarf and shouted, "Take the hit and then surprise with Payback and Dragon Claw!"

As soon as Krookodile approached Dice, he snapped his jaws into the Scrafty's shoulder, which caused him to scream. Dice managed to let himself go from Krookodile's grip, an electric burn forming where Krookodile had crunched him.

Dice quickly recovered from that as his forehead gleamed a maroon color, and he rammed into Krookodile's torso like a cart hitting a brick wall. He followed up with green draconic flames swirling all around his fist and slashing across his chest. Krookodile growled and took a few steps back–there was a large gash where Dice had left.

Back at the sidelines, Acerola and Selene cheered while Molayne and Lillie's eyes grew wide with excitement. Nebby roared, as if cheering too. Tapu Bulu made a sage nod, seemingly not worried about Nanu's outcome yet.

A disappointed grunt escaped from Nanu, and he narrowed his eyes. "I think you had enough fun with that punk, Krookodile. Hit him with Dragon Tail!"

Having already seen Dragon Tail being used firsthand, Grimsley knew his Pokémon needed to act fast. He called for Dice to use Ice Punch and watched as the Hoodlum Pokémon's fist was covered in cold mist. Krookodile was about to slam his tail onto Dice, but he acted first and punched at its tip. A part of Krookodile's tail immediately froze.

A wicked grin stretched across Grimsley's face. "Now for High Jump Kick!"

Dice nodded at Grimsley and launched himself in the air.

"Break that ice and try Thunder Fang again!" Nanu countered.

While Dice was still in the air, Krookodile slammed his tail on the ground and shattered the ice into several pieces. He looked up and opened his jaws, sparks of electricity flying out from his mouth.

Dice fell back down quickly, like a falling Minior. He managed to avoid Krookodile's jaws by changing the angle of his leg and kicking the side of the crocodile's face. This time Krookodile roared and collapsed on the ground.

After Krookodile didn't get up for several seconds, Kukui raised his arm and declared, "Krookodile is unable to battle! The first win goes to Grimsley!"

NANU

Upon hearing Kukui confirming that the first win went to Grimsley, Nanu's chest tightened. It was about damn time one of them took out one of their Pokémon. Still, he couldn't let that loss get to him already. Back at the sidelines, Selene shouted, "Way to go, Grimsley!" while Molayne clapped and praised, "What a great first win!"

After Nanu pulled out Krookodile's pokéball and returned him, he said in his most soothing voice, "Great work, Krookie. You take it easy now." He gave Grimsley a narrowed stare. "Not bad, but we still have a long way to go."

Nanu took out another pokéball and released Sableye. The moment she appeared, the Darkness Pokémon flashed a toothy grin and jerked her head. She should be a good counter against Dice and his fighting moves would be useless against her, but Nanu was certain Grimsley would find a way against that. He overheard Lillie and Selene commenting on strategy ("I'm sure Grimsley will still pull through, yeah!")

Both he and Grimsley called out for their Pokémon to use Ice Punch. Dice and Sableye's fists shimmered in blue light and they rushed at each other. They kept throwing punches at one another, and each time the impact made them bounced off. It was like seeing a boxing match where both participants were fully focused and not backing down, ebb and flow.

Now things were getting interesting.

The first time Nanu met Grimsley, he thought the man was an annoyance. The best of the best from Unova who decided to take a holiday in Alola on a whim. After his encounter with the Totem Mimikyu, Mimikins, Grimsley acquired a Ghostium-Z and wanted to battle him. Without a second thought, he said no, crushing Grimsley's spirit.

After Dice and Sableye went to their icy boxing match for a while, Grimsley changed tactics and had Dice use Dragon Claw. The Scrafty's fist burst with green draconic energy and he bolted towards Sableye. Nanu made Sableye counter Dice's Dragon Claw with Power Gem, showering him with gleaming rock gems and pushing him back.

"Keep up the pressure by using Mean Look and Shadow Sneak!"

Sableye tilted her head and cackled. She fixed her stare at Dice, her eyes glowing blood-red. Dice's whole body tensed up, as if he was unable to escape. That got a reaction from Grimsley, his eyes growing wide and him lowering his chin.

Keeping the momentum up, Sableye followed that up by having shadowy tendrils sneak up behind Dice and grab his waist. Dice yelped in surprise and struggled to let go.

"Nanu made a great choice having Sableye use Mean Look and Shadow Sneak together!" Kukui praised. "That assures Grimsley won't be able to switch Dice out during this battle!"

Not about to be deterred, Grimsley yelled, "Keep trying to escape from Sableye's Shadow Sneak and go for Payback!"

"Finish the Scrafty off with Power Gem!"

It took several more attempts until Dice pushed through and was freed from Sableye's shadowy clutches. Once Dice's forehead glowed, he collided with Sableye and caused her to stumble back several steps. As per Nanu's command, Sableye fired off many rock gems straight at Dice's chest and face. The sheer impact of the Power Gem was so great that Dice crashed on the ground that instant.

With a raised arm, Kukui said in a booming voice, "Dice is unable to battle! Nanu and Sableye win this round!"

"Yay, Uncle Nanu!" Acerola cheered, pumping her fist in the air and jumping up and down. Lillie and Selene excitedly commented on the moves used while Molayne made a small frown as if taken aback by Grimsley's loss. Nebby's roar was louder than when Grimsley won the first round.

A calm look washed over Tapu Bulu's face at first. A brief moment after, he let out a joyful, "Bulu, lu!"

Grimsley's face hardened and his expression relaxed soon after. He grabbed Dice's pokéball and returned him.

"Thank you, Dice, you did wonderfully," Grimsley said in a low and proud voice. He pulled out a pokéball. "Time for you to shine, Roulette!"

The second Roulette, Grimsley's Absol, was released, she craned her neck and howled. Her luxurious fur and the Absolite that hung on her neck gleamed in the Alolan sun.

"Wait, is that an Absolite on Roulette's neck?" Selene asked.

"It is!" Lillie responded with an eager smile. "We might get a chance to see Mega Absol soon!"

Nanu's breath slowed upon him seeing Roulette. He had seen Grimsley Mega Evolve her when they were going against Necrozma, so Nanu knew that Absol was capable of some powerful moves. It would be a good idea to take her down as soon as possible.

"Sableye, use Mean Look before that Absol can act!"

"Prevent yourself from getting affected by Mean Look!"

Sableye glared at Roulette and once more her eyes glowed red. Fortunately, Roulette had set up a rainbow barrier around her, making Mean Look useless. He should have expected Grimsley to learn from the last time Sableye used Mean Look.

Grimsley next called for Roulette to use Shadow Claw, and Roulette's paw was shrouded with dark shadows that formed into a large claw. She pounced on Sableye and left two deep slashes on her face. Once Roulette jumped off from Sableye, the Darkness Pokémon grimaced and rubbed her face in agony.

"Shadow Sneak now!" If Sableye couldn't use Mean Look, Nanu had to improvise and have Roulette trapped like how she did with Dice.

"Hurry and slash it off with your scythe!"

Sableye screeched and summoned shadowy tendrils once more while Roulette made a stance and the scythe on her forehead glowed dark-type energy. Grimsley's Absol was able to hack all of the tendrils coming at her and launched at Sableye, slashing at her chest. That made Sableye cry out in pain as a deep wound appeared.

Roulette didn't give Sableye a chance to recuperate as she leaped up in the air and crashed into her, landing another hit. Some cloud of dust flew up, and once everything was cleared it was revealed that Roulette was still standing while Sableye laid down and didn't get up.

"This round goes to Grimsley and his Absol!"

Acerola shouted encouragingly, "Don't worry, Uncle Nanu, you still got this!" Meanwhile, Lillie and Selene erupted in cheers and Molayne gave a satisfied smile.

Agitation rising deep within, Nanu made short, fast breaths. Now Grimsley had taken down two of his Pokémon while he only managed to knock down one of his. He could still turn the tides of this battle, so he returned Sableye and smiled down at her pokéball.

"You did great, Sableye. We'll be able to handle things from here."

Just as Nanu was about to contemplate which Pokémon he should bring out next, he flinched when he heard "Bulu!" from above. Tapu Bulu ascended down and floated in front of him. He raised a brow at him.

"Do you want to join in the fun, now?"

Tapu Bulu nodded and screamed out an eager, "Bulu!", confirming that he wanted to battle. A smirk formed on the corners of Nanu's lips.

"Good. Let's get started then!"

Happy to be battling, Tapu Bulu let out a booming voice and twirled around. A field of green mist appeared and covered most of Lake of the Moone, everyone looking around in awe.

"Looks like Tapu Bulu's Grassy Surge has activated," Molayne said.

Grassy Surge acted the same as Grassy Terrain. Tapu Bulu's ability healed any Pokémon active on the battlefield but also made Tapu Bulu's grass moves stronger. Nanu could use that to the Aloan Guardian's advantage.

Shortly after Grimsley went away with Kukui, his former partners from Interpol Anabel and Looker came to visit him to bring him up to date on their investigations on the Ultra Beasts and the Aether Foundation. He had also gotten in contact with Wicke Charlotte Santana, who was working undercover.

Little did he know, dark secrets were lurking in Alola.

A stunned look stretched across Grimsley's face; Nanu assumed the Unovan trainer didn't expect to go against Tapu Bulu this soon. Grimsley recovered quickly from the initial shock and chuckled.

"Well, I guess it's about time Tapu Bulu finally makes their debut." He fixed his gaze at Roulette, his smile widening into a grin. "Roulette, are you ready to Mega Evolve?"

Roulette glanced over her shoulder and responded with a sharp nod and a growl.

"Perfect!" Grimsley touched the Keystone that was attached to his scarf, and both it and the Absolite sparkled. Roulette was bathed in golden light brighter than the sun, and her appearance changed. The horn on her forehead grew thicker in addition to another smaller horn. The back of her fur bristled, making her look like she had wings. Roulette threw her head back and howled.

"Alright, Mega Absol!" Selene cheered, raising her fist in the air.

"Roulette's even more beautiful in her Mega form," Acerola praised with a beaming face. "Both Uncle Nanu and Tapu Bulu should be able to handle her, though!"

Grimsley made the first move by ordering Roulette to start with Aerial Ace. She didn't let Tapu Bulu get a chance to act as she launched into the air and left a deep cut on the Land Spirit's Pokémon face. Despite the attack being super effective, Tapu Bulu didn't flinch and twirled around.

Keeping his calm, Grimsley asked Roulette to go for Shadow Claw next. Large shadows burst out of Roulette's paw, forming a claw. As she charged towards Tapu Bulu, an idea came to Nanu.

"Use your shell to protect yourself!"

Tapu Bulu hummed and withdrew into their shell before Roulette made her strike. She kept clawing on the hard shell, only leaving scratches there. When that proved to be a fruitless task, Grimsley told Roulette to stop, and she backed away. Tapu Bulu opened their shell to reveal themselves once more.

Nanu mused that he and Tapu Bulu were off to a good start. Grimsley may be ahead, but perhaps they could pull off a miracle here.

GRIMSLEY

After taking down Nanu's second Pokémon, Grimsley's heart raced in exhilaration. He thought he would keep the pace going, only for Nanu to have Tapu Bulu as his next Pokémon. That was fine, he always loved a good challenge. That was why he Mega Evolved his Absol, risk for greater reward.

The match between the two Pokémon continued with Roulette using Night Slash and Tapu Bulu's Mega Horn. Roulette's scythe filled with dark energy clashed with Tapu Bulu's thick horn. The Ula'ula Island's guardian was stronger and able to push Roulette back. Roulette shook that off and followed up with Shadow Claw, her ghost-infused claws landing a hit.

Long scratch marks were left on Tapu Bulu's face, but then their wounds glowed green and closed up. Again, Roulette used Shadow Claw, and again Tapu Bulu's wounds were healed.

Grimsley had found out Kukui was forming Alola's first Pokémon League and invited him to meet two of the trainers he chose as the region's Elite Four–Kahili, who favored Flying-types, and Molayne, who trained Steel-types. He had gotten to battle them and was impressed with their skills, and at the same time, he started to fall for Molayne. Grimsley still hadn't told his feelings about him yet, unsure if they would meet again once he returned to Unova.

He continued his training by battling against the rock star and Dragon-type specialist, Ryuki. Dice and Roulette went against his Drampa and Garchomp, the latter able to Mega Evolve. After a long and valiant effort, Ryuki was victorious. That loss made Grimsley want to prepare for his battle against Nanu even more.

Grimsley furrowed his brow and his mouth twitched. He already figured out that Tapu Bulu kept getting healed from Grassy Surge. That would be a pain, but his Pokémon would be healed too and he should be able to work around that until it was no longer active. An idea suddenly flashed before him, and he pulled out Roulette's pokéball.

"That's enough for now, Roulette!" he said while returning her. Grimsley then released Blackjack, landing on the lake and opening his jaws wide.

"Blackjack?" Lillie asked with a shocked gasp. "Wouldn't Grimlsey's Sharpedo be at a disadvantage?"

"Grimsley is an Elite Four member," Kukui said with a reassuring smile. "I'm sure he's used to match-ups like that, yeah!"

Kukui was right. Grimsley was used to going against Pokémon that could exploit his own Pokémon's weaknesses, so he made sure to have some coverage. You could never be too prepared, even when gambling.

With a powerful shout, Tapu Bulu charged at Blackjack. Grimsley already thought of a perfect counter.

"Once Tapu Bulu gets close, poison them!"

While Blackjack waited, his fin was infused with toxic energy. The second Tapu Bulu approached him, he jabbed straight at their forehead and caused them to back away.

"Oh, looks like Tapu Bulu is poisoned!" Acerola pointed out with her mouth wide open.

Indeed Tapu Bulu was poisoned from Blackjack's strike, toxic bubbles popping up on their forehead. The Alolan guardian let out a deep groan and spun around in a daze. Even with Tapu Bulu poisoned, their body was bathed in a green light and some of their wounds were healed.

Nanu's face fell and he narrowed his eyes, clearly annoyed at the turn of events. He raised his fist and called out, "Push through that poison and strike back!"

Ignoring the pain from the poison, Tapu Bulu's horn lit up in green light and they blitzed at Blackjack. At the last second, the Sharpedo formed a barrier in front of him, and Tapu Bulu bounced off from it.

Before Tapu Bulu could fight back, Blackjack's teeth were coated with ice energy and he sunk his jaws onto his opponent's arm. That caused Tapu Bulu to scream and shake their arm, forcing Blackjack to let go. Shards of ice, a small frostbite, was formed where Blackjack had crunched earlier.

Grimsley took a brief detour to Lake of the Moone and saw Colress with the Ultra Recon Squad. Lunala, one of Alola's legendary Pokémon, appeared from an Ultra Wormhole with another Ultra Recon Squad member. Colress sang praises of the legendary that caused the back of Grimsley's hair to bristle.

After that, he met with Nanu again and told him a little bit about his history. They were then rudely interrupted by Team Skull, which was a distraction while more of their members visited the Aether House and stole the Pokémon there.

This time Tapu Bulu wasn't healed and the green mist from the Land Spirit Pokémon's Grass Surge disappeared. Grimsley grinned. He had the upper hand in this battle now.

"Go ahead and use Aqua Jet!"

Grimsley knew Aqua Jet wouldn't do much damage against Tapu Bulu, but his Sharpedo could at least hit first and halt the Ula'ula Island guardian for a bit. Blackjack landed a hit on Tapu Bulu and pushed back some distance between them. Tapu Bulu retaliated by having their horns glow brightly and colliding with Blackjack. Their horns poked through Blackjack's skin and the shark Pokémon growled in agony. Eventually, Tapu Bulu let go of Blackjack and their body shook, the poison kicking in once more.

Grimsley made a stunned gasp and bit his lips. Of course, Tapu Bulu would have Horn Leech. Now they would be able to recover from some of the poison. Such a nuance.

An amused grin settled on Nanu's face, and he crossed his arms. "Don't think you'll get away that easily."

"I'm fully aware of that," Grimsley replied smoothly. He thrust his arm forward and directed to Blackjack, "Poison jab once more!"

"Withdraw and then Nature Madness!"

Grimsley's heart almost skipped a beat when Nanu shouted the second attack. He had seen Nature's Madness when Tapu Bulu used it against both Glutton and Necrozma and knew how powerful that move was. He watched as Tapu Bulu withdrew inside their shell and Blackjack's Poison Jab didn't get through it. Tapu Bulu backed away several feet, opened their shell, and launched a blast of pink energy that shocked all over Blackjack's body.

Nature Madness caused so much pain in Blackjack that he trashed and screamed, splashing the lake and making the water fly up. Eventually, the Sharpedo grew exhausted and collapsed.

"Grimsley's Sharpedo is unable to battle!" Kukui declared and moved his arm toward Nanu's side. "This round goes to Nanu and Tapu Bulu!"

Back at the sidelines, all of the girls cheered while both Molayne and Nebby's faces remained neutral. Grimsley let out a disappointed sigh and returned Blackjack.

"You were magnificent, Blackjack, take a good long break," Grimsley praised with a small smile.

"Wow, Tapu Bulu looks to be as strong as Tapu Fini!" Selene said with a beaming face. At that moment, Grimsley mused his first meeting with Selene.

He first met Selene, Lillie, and Hau at the Aether House after the place was ransacked by Team Skull. Selene wanted to go save Gracie's Yungoos, and Grimsley battled against her to see if she was capable of that. Despite losing to him in their battle, she proved her worth and decided to help her out.

After they met with Gladion, he and the young trainers asked for Nanu's assistance, and to Grimsley's surprise he agreed to help also. They invaded Po Town and went against several Team Skull grunts. Everything went smoothly until Guzma showed up and his Mega Pinsir exhausted most of their Pokémon. They went out victorious, only for Lillie to surrender herself to Team Skull and go to Aether Paradise with them.

While contemplating his next Pokémon, Grimsley's stomach churned. All of his Pokémon except for Queen wouldn't be able to withstand Tapu Bulu's Nature Madness for long. He didn't want to bring her out yet though, and it was best for Roulette to rest a little more.

He opted for Raz and released her, the cat Pokémon stretching out under the later afternoon sun. The best course of action was to exhaust Tapu Bulu as much as possible.

After giving his command, Raz's tail shined brightly and she charged at Tapu Bulu. She whacked her tail at the legendary, but they dodged in time. Tapu Bulu's horn glowed and they were about to use Horn Leech, only for Raz to evade that and fire a Shadow Ball into their face.

Already Tapu Bulu was Grimsley's toughest opponent yet. Even then, he would still lay all of his cards on this match.
