I should have been more upfront with you regarding Sun's Pokémon team. For the League, Sun will use Decidueye, Hawlucha, Noivern, Zoroark, Turtonator and Necrozma/Nebby. Please do not comment about changing Sun's Pokémon, as they were my own team in Ultra Sun.
Thank you for your patience as you await the next chapter. And now...
"Light..."
I move around the city in a frenzy as humans flee at the sight of my darkened form. The pain is unbearable as I try to find any source of light to eat. The humans' machines... they waste so much of the light that I give them! No wonder why they kept asking me for more! These humans did not have to worry about conserving light; they can just ask their Blinding One for more! These humans watch as I consume the light from their machines, only to find that it is not nearly enough. The light also leaves my form faster than I can process it due to that accursed injury!
"Light!"
"Light? That's what he wants?"
"We should take him to the Blinding One; maybe he can help!"
Fools! Do they not realize that I am the Blinding One! I move menacingly towards the humans watching me. Before I can take the light from them and their Pokémon, a group of humans in strange suits step between us to intervene. I move back to see these suits are holding weapons, aimed directly at me.
"Don't move! Ultra Commander Poseidon to Central, we have the unidentified creature surrounded. Permission to capture?" Capture? No, you will not contain me!
A barrage of lasers and nets head towards me, which I deflect with my crystals. My claws strike, which blows away the suits and humans like the peons they are. I may be satisfied from defeating these humans, but my hunger for light is nowhere near satisfied. There is only one thing left to do.
I look towards the sky and spread my claws. Everything around me becomes as dark as my current form; the sky, the machines, the humans and Pokémon themselves. My brain prism glows a pure, intense white as I take in the light of this world. I scream in agony as I process this light, for I quickly realize that it leaves my form as fast as I can process it. The light... the light barely fulfills my appetite. I still want more. Clearly, I cannot get enough light from this world, so I must find another source.
I float away and open another Wormhole, leaving these humans in my wake.
All of us walk toward the building atop the mountain, where we see a man in a lab coat and no shirt standing at the entrance. I lunge forward, ready to strike the man down, but Sun's hand stops me.
"Shhh... It's okay, Necrozma. He's not going to hurt you. Hi there, Professor Kukui!"
"Hey there, Sun! I can't help but remember when you first chose Rowlet back on Melemele Island, yeah! And now, you've got a full team and... is that Necrozma and Solgaleo, fused together?"
"Yeah, it sure is!" Sun and the man called Kukui both come close to me. I face Sun, not looking at Kukui.
"I found Necrozma as I was climbing Mount Lanakila. He was badly hurt, so I healed him. Nebby agreed to fuse with Necrozma to help his pain."
"Ah, I see! Look at you. You've made it through all the trials and grand trials that make up the Island Challenge! Not to mention, you saved Necrozma and the light of Alola! Congratulations!"
"Thanks! Uh, aren't you cold, Professor?"
"Naw, I'm fine! The fire in my soul rages hotter than a Blast Burn! I'm toasty warm! Besides, there's something far more important, Sun... and that's taking on the Pokémon League!" The freezing wind that almost ended me in the crater blows around us, causing Kukui to shiver and sneeze.
"Now, (Kukui sniffles) let's get you guys in there! Just so you know, once you enter, you cannot leave until you either win it all or wipe out." Heh, if I could escape from that blasted Tower, this building should be no problem at all. Sun notices the look in my eye and gives me a look of his own as Kukui continues speaking.
"Every Pokémon League in every region features four fantastic trainers called the Elite Four. You can challenge them in any order you want, but you must beat them all... or be beaten."
"Sounds... good!" I can sense Sun's uneasiness in his reply. Apparently, so does Kukui.
"Relax, cousin! Even Necrozma can tell that you're nervous! It'll be fine!"
We enter the building, where the doors immediately close afterward. Around us, there are four walkways, each leading to a different door. One door is made of metal, one is made of rocks, one is made of fans, and the last door is just a strange purple gale. What could they mean? Is that what we are supposed to face? Kukui leads us to the center platform before he faces us again, gesturing towards each door.
"Our Elite Four consists of my good friend Molayne, the Steely Scientist! Olivia, the Rocky Akala Island Kahuna! Kahili, Champion Golfer and Flying expert! And finally, Acerola, the Ghostly royal descendant! Now, if you're able to beat all four, I'll take you to the Champion's room to cement your title! If not, I'll call for an ambulance to take you to the Pokémon Center!"
"Huh?"
"Just kidding Sun; I know you'll do great!"
Kukui laughs as Sun's Pokémon and I roar with enthusiasm. "That's the spirit! We've always had the Island Challenge finish on Mount Lanakila, so it made sense to build the League here, to honor and show our respect for our Legendary Pokémon. It should be a cakewalk if you have both Nebby and Necrozma on your team!"
"Sorry to disappoint Professor, but they're just going to watch. I want to experience the full force of the Pokémon League with my team, so Necrozma and Nebby will be my last resort if I need them."
"Giving yourself a tougher challenge even here... you remind me of me when I competed in the Indigo Plateau. The Gym Leaders and Elite Four there gave my team an All-Out Pummeling! When everything seemed lost, I saw my team battling for me through it all, pouring their souls into their moves for me. But, enough about me! This is all about you and your team! So, who will you challenge first?"
Sun looks at all of us, confused. "Um, we actually haven't decided yet. Wait, I know!"
Sun pulls out a strange red device from his bag. This device springs to life and floats in midair, with arms, eyes and a mouth. It beeps for a moment before speaking in an unusually high-pitched voice. "Alola, Sun! What can I, Rotom Dex, do for you?"
"Hey Rotom, can you help us decide who to challenge first in the Elite Four?"
"But of course! Calculating... Calculating... According to a random algorithm that I created, your first opponent should be... Kahili!"
"Then it's settled! Let's go challenge Kahili! See you later, Professor!"
"Good luck, Sun! I'm looking forward to seeing you become our first Champion!" Sun leads us down the walkway to the first door. I turn around, where I notice Kukui waving at us. I gently nod at Kukui before continuing on with Sun.
As we enter the first room, I notice there are wings of light scattered throughout the room. These wings remind me of the wings I once held in my true form. Could it be... Before I can contemplate any further, a girl wielding a strange club greets us.
"Alola! And Alola once again! My name is Kahili."
"It's nice to meet you, Kahili! I am Sun, and this is my team!" We eagerly roar to show our support for Sun.
"It's nice to meet you and your Pokémon, too! A few years ago, I was an Island Challenge Champion, just like you. Since then, I left Alola to improve my skills as a trainer and as a Golfer. When I heard that Kukui was creating a Pokémon League in Alola, I knew that I wanted to be a part of it!"
"Oh, wow! You must be really strong!"
"You bet! Now, have a look at my fantastic Flying-type team! And to start things off, here's Hawlucha!" Kahili sends out her Hawlucha, who glides all around us. It's quite fast, and from what I can tell, well trained.
"A Hawlucha, huh? Then I'll take on your Hawlucha with my Hawlucha!" Sun's Hawlucha jumps onto the battlefield, eager to battle. Kahili studies Sun's Hawlucha for a moment before responding.
"A battle between two Hawluchas? This should be quite fun! All right, let's begin!" Both Hawluchas lunge forward, locked in position with neither one giving an inch to the other. As the two Hawluchas lock eyes, I can sense the pride between them is strong. They want to see who is stronger. Eventually, Sun's Hawlucha overpowers his opponent. How could that be, when their strength appears to be equal? I look to Sun for an answer, and I find it. In his eyes, and in Hawlucha's. It was pure determination and trust that made all the difference.
I then look to Kahili, who calls back her Hawlucha.
"I have to say that I was not expecting your Hawlucha to win so easily. But, you have done a wonderful job raising him!" Sun's Hawlucha poses in his victory.
"Now, meet my next partner!"
As Kahili's Mandibuzz falls, Sun's Turtonator roars in triumph. Both Sun and Kahili look at each other, before Kahili pulls out her last Poké ball.
"So it's come down to the 18th hole! Toucannon, let's fly!" Toucannon takes to the battlefield, its beak glowing red. Could it be trying to avenge its fallen comrade? Whatever Toucannon's motivation is, Turtonator is exhausted from its battle with Mandibuzz. But, it looks like it can keep going.
"Turtonator, it's time to take a Rest!" Sun's Turtonator closes its eyes as a blue aura surrounds its body.
"This is no time for a Rest! But if that's your thing... Toucannon and I will take the shot!" I cannot help but notice Toucannon's speed. It's quite fast. But Sun's Turtonator remains resolute and unmoved, taking the attacks with no response. Both trainers use their Pokémon's strengths to their advantage.
"Toucannon, finish this with Brave Bird!" Toucannon moves to strike once more. As it gets close, Turtonator opens its eyes and turns around to face Sun and I. It is then that I see Turtonator and Sun smiling at each other.
"Quick Turtonator, use Shell Trap!" Turtonator's shell spikes glow a deep red as Toucannon makes contact with them. A huge explosion fills the room, knocking Turtonator and Toucannon back. When the smoke clears, Turtonator is fine, while Toucannon falls on its back for a moment before it gets up.
"Your Turtonator is quite strong! But now it's time to break out my Ace! Toucannon, let's do this!" Kahili makes a pose as an aura transfers from her to her Toucannon. This aura... it's the same as when Sun fought against me. More importantly, it is quite similar to the aura that I once emitted as the Blinding One.
"Higher! Stronger! Faster! The winds of change... Become the burning wind that flies across the fields of Alola!" Her Toucannon quickly ascends to the sky before descending even faster towards Turtonator. I can already see how this battle will end. Before I move forward to take Turtonator's place, Sun puts his hand in front of my face to stop me.
"Supersonic Skystrike!"
"Turtonator, use Endure!" Turtonator puts its hands up to block the attack. For a moment, neither side moves. Another explosion occurs, this time with Turtonator falling on one of its knees, while Toucannon is pushed back towards Kahili. If either Pokémon takes another hit, this battle will be over.
"Now's our chance, Turtonator! Use Shell Smash!" Turtonator glows white as Toucannon is pacing around slowly, clearly tired from using the Z-move. Sun makes his own pose as an aura transfers from him to Turtonator.
"A blazing fire, too powerful to extinguish! Blessed with the flames of Wela Volcano, infused with passion! Scorch your rival and leave the earth singed with Inferno Overdrive!" Turtonator launches its Z-move at Toucannon, who only snaps out its daze as the move hits it.
When the smoke clears, Toucannon falls, knocked out from its battle. Kahili recalls Toucannon back to its ball before sighing. Whatever disappointment I sensed from her was quickly hidden as she smiles at Sun, who now runs to hug Turtonator.
"It may be frustrating to me as a member of the Elite Four and a former Island Challenge Champion, but it looks like your strength is a real albatross. In golf, that's a good thing!"
"Uh... thanks?" Sun looks puzzled as Kahili laughs it off.
"You know... I think you'll bring a breath of fresh air to the Alolan battle scene! That battle was worthy of being number one in Alola... maybe even number one in the world!" Kahili swings her club towards the wings of light, where a portal opens up.
"That portal will return you to the room you entered from so you can continue your Pokémon League challenge. There are three more members of the Elite Four left, each of whom is a top-class trainer. Best of luck!" Sun leads us towards the portal. As we enter, Kahili calls out to Sun.
"Sun? Next time we battle, I want to take on that cool-looking Solgaleo you've got there!" Kahili points to me. "And I'll win! You'll see!" Sun looks at me, and I growl my approval. I look forward to crushing her Pokémon team the next time. For Sun.
"It's a deal!"
We return to the center platform that we started at, only to find that the man named Kukui is nowhere to be found. Sun pulls out the strange Rotom device again.
"Now, who should we challenge next, Rotom?"
"According to my calculations, your next opponent should be... Molayne! But first, you should heal your Pokémon. It doesn't make sense to take on an Elite Four member with a worn out team, right?"
"Oh yeah, I almost forgot!" Sun pulls multiple bottles and brushes out of his bag and tends to all of his Pokémon. As he approaches me, I kneel so he can brush my crystals.
"So, what did you think of our battle, Necrozma?" I do not want Sun to know how I truly feel, so I nod and gently growl without a word. Deep down, the determination and strength of Sun and his Pokémon team impressed me.
"It's all right, you don't have to answer. I know you're still getting accustomed to this." Sun smiles at me as he strokes the crystals below my mouth. Even if I cannot actually feel his hands on my crystals, I find the act soothing. Nebby seems satisfied, as he wags our tail... or is that me? What's going on? Sun does not seem to notice as he looks at the rest of his Pokémon.
"Let's go challenge Molayne, shall we?" We walk towards the metal door, only to find that it does not open. Sun tries again, with the same result.
"Huh, I guess it's locked. Maybe Molayne's challenging someone right now..." The Rotom Dex comes out of his bag, almost out of instinct.
"Recalculating... recalculating... done! We should challenge Olivia next!"
Flashback
After Sun and his Pokémon enter Kahili's room to challenge her, Professor Kukui pulls out his phone to make a call.
"Phyco? It's Kukui. I've found Necrozma. He's at the Pokémon League."
"Is he alive?"
"Yeah, Necrozma is alive. Sun caught him on Mount Lanakila and is now about to challenge our League."
"Sun... captured the Blinding One? How could that be? He's in danger if he thinks he can control Necrozma, especially if Necrozma runs wild again!"
"I don't think Sun wants to control Necrozma. I think he wants to help Necrozma. And as far as I can tell, it looks like Necrozma is doing all right now. Just have a little faith in them!"
Before Professor Kukui could say anymore, Hau walks through the door.
"I gotta go. I'll keep you posted, cousin!" Professor Kukui ends the call as Hau walks up to him, waving.
"Alola, Professor!"
Necrozma's nature: Adamant.
Characteristic: Strong willed and Proud of its power (tied).
Joining Sun and his team: Priceless.
I hope that you've found the dialogue to be better between characters. I tried to change the characters from speaking in a monologue (since the player rarely speaks in Ultra Sun/Moon) to speaking in a more conversational format. Most of the characters here will use a combination of dialogue from the game as well as from the anime. For example, the line where Sun asks if Kukui is cold is derived from a scene in the anime between Kiawe, Hala and Kukui.
I decided to give Sun the Rotom Dex from the anime, as evidenced by the high-pitched voice. Most of the characters in the anime are more fleshed out than they were in the games. However, that does not mean that I will always use the anime version of a character. I will use whichever version of the character that I believe adds more to the story, and that includes mixing the game character with its anime counterpart.
If you have not figured it out by now, the italicized text at the beginning of each chapter refers to the incident in the ancient past that caused Necrozma to lose his light, and his attempt to regain it the first time. The italicized scene at the end of this chapter is a bonus scene, which may or may not have a role in future chapters. In the bonus scenes, Necrozma may or may not be the narrator. These scenes are subject to change.
A note about updates: They will come when the chapter is ready. There is no need to update on a regular basis if it does make the story the best it can be. I wrote out a summary beat sheet and outline for each chapter in order to better organize the story and how I want it to go. It took a lot longer than expected because I added additional chapters along the way. With that in mind, there are 27 carefully planned chapters in total, including what was already written. Just like everything else, however, this is subject to change without notice.
Chapter 5 will be titled, "Radiance."
I want to know how I can improve as a writer, and/or how I can improve the story, so please leave a review if you can. Be suggestively constructive, not aggressively destructive in the comments. Thank you.
