Okay so looks like Team Rocket will stay. Now it seems some people may have missed some info, or I forgot to put it in. Serena still went to Hoenn, but she will visit Ash, and vice-versa. Next, Ash already has a legendary, I had him caught Zygarde, so he can keep Greninja. Now if you're wondering if he'll catch other legendries, only a few. Which ones, I'm thinking Meloetta, Ho-Oh, Lugia, Hoopa, Azelf, Mewtwo, and maybe Latias, and Latios. Now there were a few things I forgot to mention, Pokémon will learn a maximum of twenty moves. The reasons is because I going have Ash use fusion moves, so I need a large number of moves. Now on to the Pokémon Ash will get. He can catch any Pokémon found in Alola, but any Pokémon that can't be found in Alola will have to wait until he leave Alola to visit his friends, or his mother. Also Team Rocket will have a surprise for you in this chapter.
[At Prof. Kukui's place]
Ash was currently training his Pokémon, except Deino who was giving the day off in order to rest. Ash's Fennekin and Shinx were currently practicing the moves against each other. Ash was currently trying to get Fennekin to learn Flame Charge, while Shinx was practicing Bite. They training was going well as they show signs of perfecting the techniques. Fennekin was able to summon flame around it, but not for long. Shinx's teeth would glow, before it would disappear. Since they were around the same level, they were perfect training partners.
Flying over the water, Pidgeot was practicing going through some hoops, practicing a new combination attack. So far everything was going well, but every now and then Pidgeot would lose control. However Pidgeot's determination kept it going, and making sure it would master the move. Over on the shore Croconaw burrowing in the sand, practicing his Dig attack. Since Croconaw couldn't learn many ground-type moves until, he evolved, Dig was there only option. Next by some rocks Pikachu was show Arbok, how to use Iron Tail. Arbok, so far has been able to leave large dents in the rock, so Ash guessed he wasn't too far off. Torkoal was Gible were having their own battle, with Deino watching, since Deino, and Ash's other Dragon types met Gible, they been asking him to teach them Draco Meteor. So far Gible's helped Goodra, and Noivern have gotten the hang of it.
They continue, to train till it was time to eat, once they were finished, Ash had them demonstrate their progress. Kukui was also there, since he wanted to see what Ash was working on. Surprising both Ash and Kukui they had master the moves they had been working on. Once congratulating on their work Ash returned them to their Pokéballs, Pikachu leaped on Ash's shoulder, as they bid goodnight.
[The next day]
Ash, was currently in Prof. Kukui's lab, watching as the Professor was typing away at his computer. In Ash's hands was a strange device, according to Kukui, it was a Poké Dex. However it was missing a power source. Suddenly the electricity went wild, as one of the Rockruff began to whimper. Suddenly, a Rotom appeared from an outlet, before charging into the Poké Dex. Caught off guard Ash examined the dex expecting something to happen. Suddenly the Poké Dex sprung to life, as a face appeared it. It didn't long for Ash to realize that Rotom, is the Poké Dex.
Rotom then began scanning the room, as greeted him with Alola.
"Language selection complete."
"Woah it talked."
"Rotom, please lend Ash a helping hand, from now on." Kukui spoke.
"Understood, Ash user registration complete. Poke Dex, now loading." Few seconds went by before Rotom spoke up again. "100% Alola! Nice to meet you Ash."
"Wow, we can even have a conversation." Ash asked.
"Of course, Rotom Dex to equip with an assortment of languages. I have been program to communicate with people of all different kinds." Rotom stated proudly.
"Awesome!" Ash stated.
"Awesome! Does not compute. Does not compute." Rotom said in confusion.
"Ash was just said, he was very impressed with your capabilities." Kukui answered him.
"I understand, awesome means excellent. I'm other words Rotom Dex is excellent." Rotom stated proudly.
A few minutes went by, as Kukui introduced himself, and Rotom explained his capabilities. This lead to Ash having Pikachu scanned by Rotom, before Rotom pulled Pikachu's tail, leading to everyone getting shocked. Once that was done, everyone got ready as they made their way to the Pokémon School.
[Elsewhere]
A red headed woman, and blue haired man had exited a plane, followed by what looked to be a cat and some kind of blue creature dressed as people, as they began talking amongst themselves. It was Team Rocket, longtime enemies of Ash, despite helping him save the world several times. It was clear they were here to steal the Pokémon of this region, as they began walking into town.
[At the Pokémon School]
Once Ash arrived at school, and was in class, he introduced his new Rotom Dex to his classmates, as the awed at the Dex.
"Hi, there Rotom Dex, my name is Mallow nice to meet you." Mallow said, as she introduced herself.
"Nice to meet you." Lana added.
"Nice to meet you." Rotom greeted back.
"A Poké Dex, with a Rotom inside, that's incredible." Lillie complemented.
"Incredible? Incredible means awesome, which means Rotom Dex is awesome." Rotom stated proudly.
"Yes, you're very awesome." Lillie stated.
"Wow, it learned how Ash talked. I wonder, just how this Rotom Dex was programmed." Sophocles said, before taking out a screw driver. "I'm going to analyze your programmed for just a second Rotom." Which managed to startle him.
"No thank you." Rotom retorted.
"Oh come, don't be like that just a look."
"No, I refuse, I refuse."
However, before Sophocles could press on, their teacher, and principal entered the class room.
"Oh a Rotom Dex, well you seem to have an interesting item there." Samson stated.
Once they two Rotom introduced himself, Samson, began making Pokémon puns, much to Rotom's confusion. Once Mallow explained it, Rotom began download puns, before joining Samson in saying puns.
"Alright class for today, let's do some field work. So Ash now that you got yourself a Rotom Dex, let catch a wild Pokémon." Kukui said, cause the class to get excited. "For Ash, the Alola Pokémon will be a new challenge. So I'll Destiny Bond him, to you guys."
"Destiny Bond." Rotom said, as began explaining the move. Once that was done, the Professor congratulated Rotom, before he allowed everyone to leave with Ash. Ash and his classmates took off into the forest with Rotom following.
[Somewhere in the forest]
Team Rocket, were currently in the forest, looking for new Pokémon to capture. However, they had an uneasy feeling, as they continued to walk through the forest. Suddenly, something jump out into the open causing them to scream. It was a Pokémon wearing what looked like a Pikachu cloak, but do to them never seeing Pokémon like this, they freaking out with the head of the cloak, fell back. Once they realized it was a Pokémon wearing a Pikachu cloak, James took out his book on Pokémon from the Alola region. According to the book, it was Pokémon called Mimikyu. Deciding to catch Jessie, called out an old friend.
"Go Seviper."
"Seviiiiper!" A large snake-like Pokémon appeared.
Since they had done well in the Kalos region, they had been allowed to bring their old Pokémon to the Alola region.
"Seviper use Night Slash."
Seviper charged at the small Pokémon, who took the attack. However much to their surprise, it didn't seemed to do anything. The head of the cloak, only flopped back before launching a black, and purple sphere which caught Seviper off guard. However, Seviper quickly recovered before charging at Mimikyu.
"Seviper, Poison Jab."
"Viper!"
Seviper's tail glowed purplish, pink as it slammed into Mimikyu, who took major damage. However Mimikyu wouldn't back down, as it hit Seviper hard with a purple claw. Seviper hissed in pain as it was pushed back, but the counter with another Night Slash. Mimikyu flew back, and was showing some signs of a struggle. Still it wouldn't back down, as it charged.
"Seviper, use Flamethrower."
Seviper opened its mouth, as it unleashed a torrent of flame. Mimikyu, was once again knock to the ground, as it struggled to get up. Jessie then threw a Pokéball at it, as it connected. Ball the ball shook a few times before it stopped, confirming capture. Once it was done Jessie picked up her prized capture, before thanking Seviper for its hard work. Once returning Seviper, Team Rocket, continued to walk in the forest looking for new Pokémon.
[Back with Ash]
As Ash, and his classmates walked into the woods they stumbled upon, a little like Pokémon with two pinches. Deciding to make it his first capture, Ash asked Rotom for some information first.
Grubbin; The Larva Pokémon: A bug type. Its strong jaw enables it to scrape trees, and slurp out the sap. It normally lives underground.
"Ash, did you get that?"
"Got it covered Rotom. Pikachu, use Thunderbolt."
"Pikaaaaaaa! Chuuuuu!" Pikachu shouted, sending a large amount of electricity towards the beetle.
Grubbin was to slow to dodge, as it took a direct hit. Since Pikachu, didn't use full power, Grubbin was still standing. Grubbin then burrowed into the ground, before coming out to use String Shot. Lillie freaked when it appear behind him, as she scream. As Pikachu tried to dodge, Lillie scream caused Pikachu to get hit. Grubbin began pulling in to hit Pikachu, but Ash was quick to counter.
"Pikachu, Thunder Wave!"
Pikachu, released another batch of electricity, causing it to travel along the String Shot, hitting Grubbin. This caused it to fall to the ground, groaning as paralyzes took effect. Deciding to go for one more attack, Ash order Pikachu to use a Quick Attack. Moments later, Pikachu slammed into Grubbin sending it back. Taking out a Pokéball, Ash threw it at Grubbin. The ball shooked several times before it stopped, confirming capture.
"Alright, great job Pikachu."
Ash, praised his starter as he picked up his starter. He then then turned to his classmates.
"Well now that I caught a Pokémon, why don't we head back to school, so we can get him healed up."
But before they could give him an answer, smoke cover the area as laughter could be heard. Once the smoke unveiled, Team Rocket could be seen, with a smirk on the face. Once they said their motto, Ash spoke up.
"Team Rocket, you came to the Alola region to steal the Pokémon didn't you."
Then Lillie, asked if Ash new them, in which he explained everything about them. Needless to say, they immediately didn't Team Rocket.
"You make have beaten, us in the past but this time we got the upper hand twerp, Yanmega use Bug Buzz."
"Carnivine, Power Whip."
A large dragonfly Pokémon was released, as it shot a wave of red energy. Another Pokéball opened to reveal a Venus fly trap, creature, as it summon large vines. Once Ash saw, this he countered.
"Pidgeot, use Aerial Ace on Yanmega. Torkoal, Flamethrower on Carnivine."
Once Ash's two were released, Pidgeot immediately shot forward, with great speed, before disappearing shortly, and then slamming into Yanmega, with white streaks surrounding it. Yanmega flew back several feet, before straightening itself. Torkoal shot it's torrent of flames burning the vines, and knocking Carnivine to the ground.
"What, the twerp brought back his Pokémon too." Jessie said in shook.
This caused as to smirk, "I'm surprise you did that too considering how little you guys use your brains." This caused Jessie to growl in anger, as she release her other Pokémon from their Pokéballs.
"Seviper, Frillish, Swoobat, and Gourgeist come on out and help us."
"Mr. Mime, Cofagrigus, Amoonguss, and Inkay come on out."
Jessie and James, immediately gave them their orders. But Ash was prepared for this now.
"Croconaw, Gible, Arbok, Shinx, Deino, and Fennekin help out."
The new Pokémon called their names, as they immediately got ready for battle."
"So the twerp, got some new Pokémon, but it doesn't matter. Yanmega use Ancient Power, Seviper Night Slash, Frillish Bubble Beam, Swoobat Air Slash, and Gourgeist Shadow Ball!"
"Carnivine Crunch, Mr. Mime Psybeam, Cofagrigus Shadow Ball, Amoonguss Hidden Power and Inkay, Psywave."
'Pikachu Thunderbolt, Torkoal Heat Wave, Pidgeot use Phoenix Force, Croconaw Hydro Pump, Gible Dragon Pulse, Arbok Iron Tail, Shinx Spark, Deino Dragon Breath, Fennekin Flame Charge."
The two groups launched their attacks, as they collided with each other. Pikachu's Thunderbolt, overpowered the Bubble Beam, before shocking Frillish. Since Frillish, lacked Pikachu's experience, and Pikachu released a full power Thunderbolt, Frillish was knocked out. Torkoal, released another powerful fire attack that block both Amoonguss and Gourgeist attacks. Pidgeot then, dived into the fire attack, before disappearing, only to reappear slamming into Amoonguss and Gourgeist, with flames surrounding its body, before disbursing, the fusion attack was too powerful and knock them out. Seviper, and Arbok slammed their tails together, before Seviper over powered Arbok, and Arbok was sent back. Combing their attack Shinx and Fennekin blocked, Mr. Mines Psybeam, before being hit by Cofagrigus's Shadow Ball. Since they had less experience Fennekin and Shinx were knocked out. Gible's attack blocked the Ancient Power, before he was bitten, by a Crunch. Due to Deino typing the Psywave attack did no damage to him, as he hit Inkay, who began to feel Dragon Breath's paralyzes. Croconaw then launched his Hydro Pump overpower Swoobat's Air Slash, sending it back.
Both Ash, and Team Rocket returned their fainted Pokémon praising them, before continuing their battle. Their Pokémon traded attacks back and forth, until all that was left was Ash's Gible, and Team Rocket's Swoobat, and Carnivine.
"Gible use Flamethrower."
But before Gible could launch his attack, Carnivine slammed him, with a Power Whip, before Swoobat, hit him with a powerful Psychic. And Just before Team Rocket, could deliver the final blow, Gible roared his name before glowing. He grew taller, as his arms, and legs became longer. The shark-like fin also grew, before the light died down, as Gible called out his new name.
"Gabite!"
"Oh, wow!" Ash, and his friends cheer as they witnessed the evolution. While Rotom scanned Gabite for info.
Gabite; The Cave Pokémon: As it digs to expand its nest, it habitually digs up gems that it then hoards in its nest. This Gabite is male, and has the ability Sand Veil. Gabite has learned the moves Iron Head, and Rock Slide.
"Gabite!" He howled his named again.
Team Rocket grew nervous as they saw the look in Gabite's eyes.
"Gabite, use Rock Slide, and then follow up with Draco Meteor."
Gabite, then create large rock in the sky before they fell trapping Team Rocket's last two Pokémon. He then concentrated his dragon energy, before launching a sphere into the air, as it exploded, and crash onto Carnivine, and Swoobat. Returning their Pokémon, Team Rocket were about to escape before, a large bear-like Pokémon appeared behind them, and picked them up, before taking them into the forest. Meowth, and Wobbuffet, soon followed in order to save their friend.
Rotom did a scanned the Pokémon before it disappear, identifying it as a Bewear. Despite everything that just, Ash went to congratulate his Gabite, as well as his friends, who were left in awe at the evolution. Even though the school just start, his time in Alola, was getting more exciting every day.
