Anon-A-Miss: The Ultimate Pokémon Adventure.

Sunset was battling Ash, practicing her skills. Her pikachu was fighting against Ash's. Both of the electric mouse pokemon had befriended each other. A rare sight to see.

"Alright Pikachu, use Quick Attack!" Sunset exclaimed, giving the command. Pikachu ran at the other, speeding up as he ran.

"Pikachu, dodge it and use Agility!" Ash cried. Pikachu jumped out of the way.

"Use Electro ball!" Sunset said, grinning at Ash. The electric mouse conjured up a ball of electrical energy and fired it at the other of it's species.

"Dodge it and use Iron Tail!" Ash yelled, confident that he would win. Pikachu dodged out of the way as his tail became a stark white. The yellow mouse struck Sunset's Pikachu with it's tail, wounding it.

"Use Thunder Bolt!" Sunset said. She'd looked into Electric-Type Pokemon to learn what they were strong and weak against.

Sunset's Pikachu summoned sparks of electricity, crackling against the red spots on it's cheeks.

"Pika-chuuuuuuuu!" The electric mouse cried out, striking Ash's Pikachu with volts of Electricity, knocking him out.

The now defeated Pikachu lay flat on the ground, bruised and with swirls in his eyes.

"Pikachu is out. Sunset wins the battle." Clemont declared. The redhead trainer walked over to Ash and shook his hand.

The raven-haired boy returned the gesture. The group of five walked to the nearest Pokemon hospital to get Ash's Pikachu taken care of and healed.

Princess Celestia sighed as she looked through the array of Photos. Each one held a picture of herself and Sunset within them. She felt awful for how she treated Sunset.

If she could, she wanted to make amends with her and see her again. But she couldn't.

The alabaster mare was interrupted by a portal opening behind her, Arceus walking through it.

The God Pokemon looked at Celestia with concern. He could tell something was wrong.

"Are you alright, Celestia? Something is bothering you." Arceus said, His voice echoing around the room.

"I am fine, Arceus. It's just...I miss Sunset. We...didn't part on the best of terms. Twilight has filled me out on the situation in the mirror world." Celestia replied sadly, looking away from the god pokemon.

Arceus understood how she felt. He'd wronged Giratina by casting him out. All His son wanted was to make Him proud. He'd spent too much time stopping Dialga and Palkia squabbling with each other.

"I can take you to her. She is in My world as we speak. She has befriended the prodigal child, Ash Ketchum. He will be good for her. She is improving and healing from her betrayal." The God Pokemon offered, making a portal next to Him.

Celestia's eyes widened at what he had said. She smiled when he told her that her little sun was healing from having been betrayed by the counterparts of the Elements Of Harmony.

"Please take me to her. I need to see her again. I want to see my little sun." Celestia begged softly, wanting to be with her daughter again.

Arceus nodded, wordlessly walking through the portal that He had created, beckoning the alicorn to follow Him.

Celestia dashed into the portal after Him, desperate to see her little filly again.

Sunset and the rest of her new friends were at the nearby Pokemon Centre in Lumiose City. Ash's Pikachu, as well as her own, had been healed by the staff.

The redhead trainer was currently watching both of the electric mouse pokemon play with each other. She smiled at the sight, glad to see her friend had found another.

As she was about to summon Fletchinder, she was interrupted by a voice she knew all too well.

"My little sun!" Celestia cried out, running towards her daughter.

The bacon-haired girl didn't have time to react as her mother, albeit in a human form, hugged her. Not tight enough to hurt, but enough that was comfortable to her.

Sunset's eyes widened as she noticed the crown on her mother's head, as well as the outfit she wore.

"Hi, mom." Sunset said, leaning into the hug as she melted in the embrace. It had been so long since she'd been held like this by her mother. She'd missed the sensation. How warm and safe she felt being against her mother's body.

Eventually, mother and daughter broke out of the embrace. Celestia's cheeks were stained with trails of tears. Her eyes red from crying.

"It's been so long, my little sun. I'm so sorry. I'm sorry I kept pushing you away and neglecting you, grooming you into what I wanted. I destroyed any possible dreams or goals you had just to make you like me. For that, I'm sorry Sunset," Princess Celestia admitted sadly, kissing her daughter's forehead.

"I forgive you, mom. I'm sorry, too. I also pushed you away. I kept focusing on studies and my revenge towards you instead of spending any time with you. I took your sunshine away." Sunset replied, sobbing into her mother, releasing her guilt and pain that had built up over the years.

Celestia merely held her as Sunset cried into her. The alabaster mare had missed having Sunset around. She wanted her little sun to come home. She wanted to spend Hearth's Warming with Sunset and be the mother she should have been.

Eventually the redhead had calmed down. She wiped her eyes as she sniffled.

"You have no idea how much I've missed you, my little sun. I know we both said things we can never take back, but we can turn back the clock and be the family we should've been. I'll spend more time with you, as much as you want." Celestia offered warmly, kissing Sunset's forehead again.

"I'd like that, mom. I've missed you, too. I want to spend time with you, sit in front of the fireplace and stay up late like we used to. I want us to do what we used to before everything happened." Sunset sniffled, hugging her mother tightly.

Celestia rubbed Sunset's back soothingly, letting her calm down against her body.

Once the redhead had calmed down, she let go of her mother and looked towards her Pikachu, who had witnessed his trainer cry against the other female next to her.

The electric mouse ran over to Sunset, jumping onto her shoulder as he nuzzled her gently, earning a scratch behind the ear.

"Pi-ka?" The yellow and black mouse asked in concern. He was worried that something was upsetting his trainer.

"I'm fine, buddy. It's alright. This is my mom, Princess Celestia." Sunset softly answered her pokemon who looked shocked at the fact that her mother was here.

The alabaster woman smiled at the sight of her daughter bonding with the mouse pokemon.

"He seems friendly." Celestia joked, smiling warmly at Sunset and the Pikachu.

"Hey buddy? You okay if my mom gives you a scratch behind the ear?" Sunset asked her starter pokemon, earning a nod and a smile.

"Pika-chu!" The electric mouse cooed, accepting the request. Sunset nodded to her mother who gently scratched Pikachu's ear, causing the pokemon to coo in pleasure.

Suddenly, Ash and the rest of the group ran over to Sunset. They looked at the woman and back to Sunset.

"Guys, this is my mom, Princess Celestia." Sunset introduced happily, watching as Ash lowered to one knee and bowed. Serena. Bonnie and Clemont did the same.

"There is no need to bow. You are friends of my daughter. I want to thank you for staying by her side and being there for her. You are invited to come to Equestria with her anytime as special guests." Celestia said softly. She was truly grateful towards them all.

"So you're sentient equines like a Ponyta or Rapidash?" Ash asked, having trained a Ponyta at one point in his life. He'd been on many adventures and met many other trainers.

Celestia chuckled at the question. "Not exactly, and we're called ponies. Horses are from Saddle Arabia." The alabaster woman explained to them.

Arceus appeared a few feet away from Celestia, opening a portal back to Equestria, signalling that it was time for her to return home.

Celestia sighed, not wanting to have to leave her daughter again. She mentally promised herself that she would visit Sunset from time to time, or ask Arceus if Sunset could come back to Equestria for a brief period of time.

"I'll see you soon, Sunset. I'll try and visit you when I can. I love you, my little filly." Celestia cooed, kissing Sunset's forehead.

"I'll see you soon, mom. Love you, too." the red-headed trainer replied, quickly hugging her mother who hugged her back.

With a flash of light, both Celestia and Arceus were gone. To Sunset, her mind felt so much lighter and clearer.

The group of five spent time walking through Lumiose City, picking up souvenirs and things like food and clothing.

Soon, night had fallen and they had all turned in for the night.

Sunset's pokemon were asleep next to her, resting comfortably against their trainer. She smiled at them as she fell asleep, a smile on her lips as she slept.
