Hello Everyone, this time I am going to write a story about Pokemon Solar Light and Lunar Dark with Ash Ketchum's betrayal story. I don't own the Pokemon and the characters. This story is an Ash and OC pairing story, and the OC is the same as the Sevestar Prince. Now let's get into the story.

Chapter 1 The Betrayal and Revelations

Out at sea, a giant cruise ship sails towards an island on the horizon. The ship bears the mark of a Pokéball, and on the deck stands a boy with a Pikachu. They gaze out at the approaching land. The boy, Ash Ketchum, is a Pokémon Trainer with dreams of becoming a Pokémon Master. After six defeats in the Kanto, Johto, Hoenn, Sinnoh, Unova, and Kalos regions, he finally triumphed in the Alola League, becoming the new Champion. This victory should bring joy to the young trainer, but his face is marred by a frown. What troubles him? The answer lies in his return to the Kanto Region.

(Flashback)

After bidding farewell to all his friends in the Alola Region, Ash and his Pikachu head back to Kanto. As they arrive in Pallet Town, they are met with a shocking sight: their house is gone. Confused and concerned, they decide to find Professor Oak to understand what has happened. However, upon reaching his lab, they are confronted with a scene that shatters their world. Professor Oak lies in a pool of blood, and surrounding him are Ash's former friends: Misty, Brock, May, Max, Dawn, Cilan, Iris, Serena, Clemont, Bonnie, Mallow, Kiawe, Lana, Sophocles, and Lillie.

Ash clutches Professor Oak's lifeless body, his voice trembling with rage and disbelief. "Why? Why did you kill him? What is wrong with you guys?" he demands.

Some of them wear wicked grins. Misty steps forward and coldly replies, "It's simple. He refused to give us your Pokémon."

"And you're just in time," Max adds with a sinister smile. Ash gasps as he notices all his Pokéballs, broken and shattered. The Pokémon inside are suffocating, unable to breathe.

"How could you do this..." Ash's voice breaks, and both he and Pikachu tremble with fury. They have just witnessed the murder of the Pokémon they cherished the most.

"Don't worry, you'll be joining them soon," Iris says as the traitors send out their Pokémon. Ash closes his eyes, resigned to his fate. Without his Pokémon, he feels he has nothing left in this world. Just as he is about to embrace death, a bright glow appears, halting the attack.

"Who did this?" Clemont yells, looking around frantically. Suddenly, a powerful blast causes all the enemy Pokémon to faint. Standing before them is a Pokémon Ash knows well, one created by Team Rocket. "Mewtwo..." Ash whispers.

"How dare you harm our prince! You shall pay!" Mewtwo declares. With a fierce Psystrike, the lab explodes. In the chaos, Mewtwo teleports Ash and Pikachu away from Pallet Town. The shock of the events overwhelms Ash and Pikachu, causing them to lose consciousness.

When Ash wakes up, he looks around and finds himself lying in his own bed. Everything in his room appears normal, making him wonder, "Was that just a nightmare?"

Ash gets up and walks towards the door, but to his surprise, instead of the familiar hallway, he finds himself in a lavish corridor bustling with people. The decor and attire resemble those from Lillie's mansion. One of the elegantly dressed individuals rushes to Ash and bows, "Master Ash, you are finally awake."

"Wait, Master? Me?" Ash is bewildered by the servant's words. The servant turns to the other staff and announces, "Hurry, inform Queen Delia that Prince Ash has woken up!"

Large footsteps echo through the corridor, and Ash wonders how many people are in this place. Soon, he sees his mother, dressed in her usual clothes but with black hair instead of brown. She hugs Ash tightly and says, "Ash, thank goodness, you are awake."

"Mother? What is going on here, and what happened to our house?" Ash asks, still hugging his mother for comfort.

Delia frowns and replies, "It is a long story. I called Mewtwo to bring you here because Professor Oak and some of your Pokémon are gone. I couldn't bear losing you as well."

Ash starts to tear up at the news. "So it was true... my Pokémon... They are all dead because of me..." He cries on Delia's shoulder.

Delia closes her eyes and gently says, "Don't worry, Ash. Some of your Pokémon are safe. Pikachu, Greninja, Charizard, and the others—they are all worried about you as well."

"Where am I?" Ash asks, bewildered. "And why are there servants and maids in our house?"

Delia smiles softly, her eyes filled with a mixture of love and sorrow. "Honey, I'm sorry to have hidden this from you. This is a kingdom that your father and I built—the Sevestar Kingdom. It's far from the seven regions you know, but close to one of them."

"What do you mean?" Ash asks, still confused and trying to process the new information.

"You see," Delia begins with a reassuring smile as she starts to glow with an ethereal white light. The brightness is so intense that Ash covers his eyes until it fades. When he opens them, he finds himself staring at none other than Arceus herself.

"Arceus?" Ash gasps, his voice filled with astonishment and confusion. "Why are you here, and why did you disguise yourself as my mother?"

Arceus, with a calm and gentle voice, replies, "I am your mother when I am in my human form. My divine nature protects me from being killed, but they did manage to injure me significantly."

Ash is taken aback, the weight of the revelation settling heavily on his shoulders. Fury builds within him, his fists clenching at his sides. "They will pay for this... How could they harm the ones I care about? What is wrong with them? Why are they doing this?"

Arceus, her expression serious, says, "We don't know their reasons, but we will find out. They will be avenged, Ash. For now, you must focus on your dreams. Continue pursuing your goal of becoming a Pokémon Master. There is a new region adjacent to our kingdom, one filled with opportunities and challenges."

"New region?" Ash asks, the prospect sparking a flicker of hope within him.

"Yes," Arceus explains as she transforms back into Delia. "It is called the Rikoto Region. The Pokémon there are unique and unknown to the other regions, offering a fresh start and new experiences."

Ash nods, trying to process everything. "Ar-no, Mom, so this is our kingdom. I want to ask you a question..."

"What is it?" Delia responds gently, sensing the weight of his words.

"Can I see Pikachu and the others who are still alive? I feel like it's my fault they have suffered..."

Delia is taken aback by his self-blame but quickly reassures him. "Ash, I know you've been through a hard time. Just be careful, okay? They've missed you and would love to see you."

Ash nods again, determination and a hint of hope flickering in his eyes. He walks outside, feeling a mix of anxiety and anticipation. As he steps into the garden, a heartwarming sight greets him. Pikachu, Charizard, Greninja, Melmetal, Lycanroc, Gengar, Lucario, Milotic, Primeape, Butterfree, Pidgeot, Naganadel, Incineroar, Goodra, Sylveon, Decidueye, Gardevoir, and an Alolan Ninetales are all playing together, their laughter and joy filling the air.

"I don't think I know some of these Pokémon," Ash remarks as he looks at the unfamiliar faces. He is referring to Lucario, Milotic, Sylveon, Gardevoir, and Ninetales. He has no idea where they came from or how they ended up on his team.

"When we were searching for your Pokémon, we found that some were willing to find you," Delia explains. "Though we are still missing some, let me introduce you to these new Pokémon." She walks over to the new additions and gestures towards each one. "Lucario was saved from the Tree of Beginning. This Milotic is from the Alola Beach; you were the one who fished it up back then. Sylveon hatched from an egg not long ago, and Gardevoir is from Hoenn; her parents were killed by poachers. As for Ninetales, she was found on Mt. Lanakila and took an interest in you since you are the Champion there."

"I see," Ash murmurs, absorbing the information.

Pikachu is the first to notice him and immediately calls out, ears perking up and eyes lighting with excitement. The little electric mouse dashes toward Ash, followed closely by the others. Ash finds himself surrounded by his beloved Pokémon, some tackling him playfully while others stand back, smiling warmly.

He pets Pikachu and Charizard, feeling their familiar warmth. Greninja and Lucario stand beside him protectively, while Butterfree and Pidgeot circle overhead, their wings creating a gentle breeze. Milotic and Naganadel, more serene, glide over, adding a calm presence to the lively group.

Just then, memories of his other Pokémon suffocating flash in his mind, and he frowns. He had more Pokémon, but they are already gone. Ash looks around, his heart swelling with gratitude and relief. "Guys, I'm so glad to see you all. I'm sorry for everything... our friends, they are gone because of me..."

Pikachu nuzzles him, and the others crowd in closer, their presence comforting him. Charizard suddenly hits him with a playful Flamethrower, snapping Ash out of his sorrow.

"Hey! What was that for, Charizard?" Ash exclaims, wiping soot from his face.

To his astonishment, he begins to hear their voices, not just in his heart but clearly in his mind. They are all encouraging him, urging him not to give up and to stay strong.

"Wait... I can hear your voices?" Ash asks, bewildered.

Delia, watching from a distance, explains, "You have aura powers, and I unlocked them so you can hear what they are saying. Your Pokémon don't want you to give up. They are always by your side, no matter what happens."

Feeling touched and supported, Ash looks at his Pokémon with gratitude. "Guys, thank you for cheering me up. I really needed it."

(Flashback Ends)

Ash finishes recalling the events and shares with Pikachu, "And then we got to know the new Pokémon and the big family of our castle. Now, we're heading to the new region to find Professor Pinewood..."

Pikachu nods eagerly. "Yeah... I can't wait..."

As the island draws closer, anticipation builds within Ash and Pikachu. They can hardly wait to discover the new Pokémon that await them in this mysterious region.

In the cold region of Subhail City, a girl named Alice is looking at her phone as Valerie, the Laverre City Gym Leader, talks to her.

"So, you mean Sister Eve and Sister Flora are coming here today?" Alice asks excitedly.

Valerie smiles warmly. "I know you're excited, Alice. They'll be heading to Soltree Town to find you. You've become the new Gym Leader of this region, and they want to come and congratulate you."

Alice pouts. "But why can't they come here to Subhail City? They should know my gym is here."

Valerie giggles at her daughter's cute face. "Sorry, they didn't bring any warm clothes."

Sighing in defeat, Alice relents. "Fine, I'll go there." Alice ends the call and turns to Huskpuff, one of her Pokémon and her trusted partner as a Gym Leader. "Husky, we are going to meet our sisters."

Husky wags his tail and barks, bringing a smile to Alice's face as she pets him. "But I have to find a substitute Gym Leader for our work... I hope Mr. Chiu can help me."

After discussing with Mr. Chiu, the former leader of Subhail City, Alice takes out her Pokémon, a butterfly-like creature named Crystiwing. She pets the delicate Pokémon and says, "Crys, take me to Soltree Town."

Crystiwing nods, and it carries Alice as they start to fly towards Soltree Town, the place where the Professor's Lab is located.

Now this wraps up the new story, I am going to pair Ash with Alice and Kiera is pairing Rodney in my story. And I know it is weird that all of his companions are becoming this evil with no reason and they killed Professor Oak and destroyed Ash's Pokeballs so that they suffocated to death. But just bear with it. The next chapter will be the meeting with Professor Pinewood as well as Ash and Alice's first meeting. I hope you enjoy this chapter.
