Okay this is my second Pokémon fanfiction that I'll be working on. As the other this will be a harem, sorry I could help it because I like a lot of parings. So who will be in it well here is the list.

Serena (I know, she's been used a lot, but I like her character)

Aria (She is hardly used.)

Lillie (She is my favorite girl from the sun and moon anime so far, and the sun and moon game)

Mallow (She and Ash have a lot in common)

Lana (I'm not going lie she's not my favorite, but I want to give her a chance)

Diantha (A rare pairing plus she's my third favorite champion)

Ilene (Only two stories with Ash, don't worry she is twenty in this story)

Noa (I liked that filler episode she was in)

Bianca (The on from Alto she is hardly used.)

Melody (I enjoy this paring)

That is the list for this story, now for the Pokémon. Ash will bring his older Pokémon to Alola, as for newer ones, any Pokémon from the sun and moon anime so far will be caught, as well as ones you suggest. I have change a few things, in this story Ash won the Kalos league. And he did not release Goodra, or Greninja, instead he caught Zygarde, to prevent anyone from trying to, as well for a little extra fire power when he needs it, and he pick up his Pidgeot, Squirtle, Charizard, and Primeape. Also Serena still did kiss Ash, and went to Hoenn. Also I'm giving Ash the Vulpix, and Samson Oak will get am Eevee. Now on with the story.

"Yeah, this is awesome!"

Shouted a raven hair teen, who was riding a shark like Pokémon. On his shoulder, was a small mouse like Pokémon with yellow fur, red cheeks, and a lightning bolt shape tail. Swimming next to them were several other Pokémon, which included small crocodilian, a crawfish, a sea weasel, a sea otter, and oval shaped, blue tadpole. This was Ash, his Pikachu, and several other Pokémon he has caught over the years. Recently Ash's, mom's Pokémon Mr. Mime had won a raffle for a vacation to the Alola. After finding a little bit about the Alola region, Ash decided to explore it after their vacation. Before he left, Ash realize he hadn't been bonding with his old Pokémon, so decide that during his time in Alola, he would use all of his Pokémon, and rotate his teams. Ever since his victory in the Kalos League he also realized he had been neglecting his Pokémon, so this why he would should the neglect. As he continued to ride the Sharpedo, he took in the beautiful sights of the Alola region. It was incredible, with cool Pokémon, nice people, and a rich environment.

Once he got off the Sharpedo ride, Ash and his Pokémon began running on the beach. Where he unfortunately stepped on the tail, of a small cat-like Pokémon. This upset it, and shot an Ember attack, at Ash's face. After having fun on the beach, Ash return his Pokémon before meeting up with his mom, who was relaxing under an umbrella with her Mr. Mime. Where they began walking towards the Pokémon School, in order to drop off a Pokémon egg they were deliver to Prof. Oak cousin. Ash himself, had recently acquired an egg the Professor, for winning the Kalos League. His egg was brown with red patterns on the bottom while the egg they were delivering was a lighter shade of brown, with a white Z-zag on it. While walking they came a across a small beetle like Pokémon, before it disappeared into the woods.

Once they got to the school they dropped off the egg, before Ash went off to do some exploring. Leaving his egg with his mother, Ash took off with Pikachu. After a while they came across a girl who looked to be about 16, next to her were a small sea lion, a round hedgehog, a small pink, and fruit like Pokémon. Wanting to find out about the new Pokémon, he walked up them. The girl noticed himself, but before he could introduce himself.

"Look Out!" She shouted.

However it was too late, as Ash was trampled on by a bunch of Tauros. The girl then came up to Ash.

"Are you okay?"

Once getting up, he answered.

"Yeah, I'm fine."

Smiling she was about to ask something when a Tauros appeared behind her startling her, causing her to hide Ash, only for Pikachu to surprise her, which caused her to jump back.

"Hey are you scared, of Pokémon?"

He asked, noticing she didn't seemed scared."

"I am not scared, I love Pokémon, at least from a research study."

"I'm sorry, you cute out here pretty quickly."

Another girl, this one with green hair, came up apologizing, she was followed by another girl with blue hair, and a short guy with orange hair.

"It's fine." Ash quickly brushed it off, when he noticed her.

"Hey, didn't I see you fishing by the beach?"

"For, Bruxish."

She answered, remembering her brief encountered.

"Hey who know this guy?"

The green hair girl asked.

"Hi, my name is Ash, and came all the way from Pallet Town in the Kanto region."

Once Ash introduced himself to them, they then introduced themselves, Lillie was the blonde haired girl with white dress. Mallow was the green hair girl, Lana the blue haired, and Sophocles the orange haired guy. Once Ash explained what he was doing here the students decided to show him around. Once they were doing, and back outside they heard a commotion, deciding to investigate they went to the front of their school. There they saw a guy who looked to be about seventeen, with tan skin, and red, and brown hair and was wear red shorts, next to him was a Charizard, with a seat on its back. Standing in front of them were three other teen. The two guys were wearing black shorts, while the girl was wearing a white pair of shorts. All three had black shirts with a skull a crossbones on it, they also had bandannas, and a white cap.

"Who are they?" Ash asked with a frown not liking their attitudes.

"They part of Team Skull, their always trying to bully us into Pokémon battles." Mallow answered for him.

Deciding to lend the guy a hand Ash stood beside him. Team Skull called three bat Pokémon, three lizards, and three mongoose. Ash called out his Pikachu, and one of his Pokémon came out. It was his Totodile who looked ready to fight. While the teen next to Ash called out a Pokémon called Turtonator. It was a large turtle like Pokémon, with a spiny shell.

"So that's a Turtonator."

"A strong and trusted friend, a wise one." The tan teen answered.

"Salandit use Venoshock!" "Yungoose Bite! "Zubat use Leech Life!"

The 3 lizards jumped before firing a purple liquid at Totodile, while the bat Pokémon were charging at Pikachu, but Ash was quick to counter.

"Pikachu Quick Attack! Totodile Hydro Pump!"

Pikachu took off with great speed as a white trail of light followed behind him, while Totodile unleased a large torrent of water. Pikachu slammed into the Zubat sending them crashing, as Totodile's Hydro Pump sent the Salandit flying back.

"That fast." The teen known as Kiawe complemented.

The Yungoose bit on the spines on the back of Turtonator, however the spines suddenly exploded shooting the Yungoose back.

"Hey, what happened?" Ash question, he never saw something like that.

"If something touches Turtonator's spines they will explode." Kiawe explained.

"Woah cool!"

"Salandit use Flame Burst."

"Zubat Bite."

"Pikachu and Totodile dodge and use Thunderbolt, and Ice Beam!"

Pikachu quickly moved out of reach from the Zubat, before sending them a painful shock that know them out. Causing one Team Skull Member to return them. However Totodile instead took the attack, before shouting his name as he began to glow. His body grew larger, as his spikes grew larger as well, his tail and jaws grew thicker as he evolved. Once the light disappeared he roared his new name.

"CROCONAW!"

"Awesome my Totodile evolved!" Ash shouted in excitement as he took out his Kalos dex.

"Croconaw the Big Jaw Pokémon, Once it bite down on something, it won't let go until it losses it's fang. New Fangs grow back quickly. This Croconaw is male and the ability Sheer Force. Croconaw has unlock its egg move Dragon Dance, and has learn the moves Ice Punch, and Crunch."

"Wow that's awesome Crocodile!" Ash shouted in pride, while every else marveled at the evolution. "Now Croconaw use Dragon Dance, and then Crunch."

"Croconaw!" The Big Jaw Pokémon shouted before glowing with reddish, purple aura.

Once the Dragon Dance was done, he took off with new speed before chomping down on the 3 Salandit. Once tossing them, another member of Team Skull returned them.

"Time for me to finish this." Kiawe stated as began a dance.

"My full body, and soul! My whole body, burns like a red hot flames of the Akala Mountains! Inferno Overdrive!"

Kiawe shouted as light growing from him, and began flowing into Turtonator, before it launched an extremely large fireball. Once I hit the Yungoose, it create a large explosion before creating lot of smoke. Once it cleared the Yungoose were knocked out, before last member if Team Skull returned them, as the rode off on the bikes.

Once Ash asked what it was, they told him it was a special move called a Z-move that is passed down in Alola for generations. Once finding a bit more the Z-moves and their trials, Ash had to leave with his mother. Later Ash and his mother had dinner at a restaurant, before Ash decided to go on a stroll. While walking Ash felt something calling out to him, following the feeling he went a cliff were he a confronted by an incredibly creature. It was mostly yellow, and black, with white marking, and an orange plume.

Walking up to it, Ash felt it talking to him. It then reveal a bracelet, which looked like the one Kiawe was wearing. It floated towards Ash, before Ash stuck his arm out, as place the bracelet on it. It had a yellow crystal on it with marking, the creature then took off leaving Ash in awe.

Once it was gone, Ash looked at the gift he received, a smile made its way to his face. It looked like Alola would be his most interesting adventure so far.

Okay, let me know what you think, also I forgot to mention, Ash has already traded his Tauros so what Pokémon to you want him to have received. Now since this will be following the anime I'll do most episode however, I make my own episodes, and skip some stupid episodes.
