Back at the park, Ash and the others, along with their pokemon are doing their best to stop the Nihilego what has Sunset inside. Everytime the pokemon tries to use their moves to attack, the parasite pokemon either repel it with protective shield, or throws energy balls and crystals at them. Some of the pokemon either dodge, use their moves to counter it, or ends up getting hit by the attack.
Kiawe says, "I never seen that pokemon this strong before."
"I agree. Even with all four of us, that Ultra Beast and Sunset refused tos top," Lana adds.
Ash grits his teeth in anger, "There has to be something we can do."
"We can only hope we stall enough time until Mallow and the others get here," Gladion adds.
Lana panicky says, "And hope it's soon because it's coming right at us.
The boys look to see the corrupted ultra beast is spinning right at them like a top.
"Look out! Ash shouts.
Ash and his friends dodge out of the way and fallen into the snow. The creature stops and turns around to see the four kids on the ground.
In a stern tone, Sunset threatens, "I'm going to ask you one more time… leave me alone!"
Ash gets up with a groan, "We can't do that! You're endanger as long as you're fused with that pokemon."
Gladion gets up as well, "Listen Sunset, the only reason you're acting like this because the Nihilego has corrupted you. You need to snap out of it."
"Just stay away from me!" Sunset angrily shouts. Then the tentacle is about to hit the two boys.
Just then, Pikachu runs past the two and his tail turns silver like iron. Pikachu is using its' iron tail, and hits the tentacle. Then lands on its' paws and grits its' teeth.
Ash smile in relief, "Thanks Pikachu."
Pikachu smiles and nods its' head. Just then, the pokemon creatures more crystals for another attack .Luckily, the friends dodge at the nick of time. They need to find a way to break Sunset's bond with the Nihilego. Question is… how?
Rarity along with everyone in the van as arrived at the parking lot of the park. As they exit the car, everyone look to see bright lights and explosion from the park.
"That must be Ash and the others," Mallow says.
Lillie brings out her pokeball as she says, "They're going to need some help.
"I agree," Sophocles says, bringing out his two pokeballs.
"Right let's help," Mallow agrees.
All three throw their pokeballs and their pokemon come out. Mallow's Steenee, Lillie's Vulpix, and Sophocles' Togedemaru and Charjabug. Everyone surprisingly gasp to see the many different creatures.
Fluttershy squeals, "This is so amazing. I never seen anything like it."
"I do admit, I do like the white fox," Rarity complements.
"That's and Alolan Vulpix. I named it Snowy," Lillie happily replies.
Princess Twilight asks, "Can we worry about this later. Right now, our friends are in trouble."
"Then let's go!" Pinkie shouts.
The others run towards the park as they look for Ash and the others. They are hoping they are able to make it to save Sunset. When the run deep in the park, they can see Ash and the others along with their pokemon.
However, Twilight, the girls, and The Crusaders gasp in shock on what they are seeing. They see Sunset Shimmer inside of a trange bell cover, and long extended crimson and yellow hair. Her eyes are dazed teal, and on the verge of tears and rage. They begin to wonder: How did all of this happen? Does this Anon-A-Miss ordeal has anything to do with it? How are they able to set her free and break the bond between her and the Ultra Beast? So many questions, so little answers.
Mallow calls out, "Ash, Kiawe, Lana, Gladion, we're here!"
"And we brought help," Lillie adds.
Ash and the other look to see Mallow and the others, along with the Main Six and the Crusaders. The three groups run to the fighting trainers with their pokemon to help them with the battle. Twilight and the other girls turn to see Sunset still in the pokemon. Sunset who is inside the bell gasp to see Twilight and her former friends. Sunset screams in fear and begin to conjure up energy balls and sharp red crystals. Then throws them directly at the trainers and the girls.
Pinkie exclaims, "Look out!"
Everyone scream and they doge and run from the energy balls and crystals hitting at them. Luckily, Pikachu and some of the other pokemon are able to use their abilities and agilities to get past the attacks.
"That was to close," Rainbow exclaims.
Scootaloo deep heavily, and asks, "Wh-why is Sunset attacking us?"
"What happened to her?" Sweetie Belle adds.
"That's something we don't know, but see you girls made Sunset upset," Kiawe says.
Applejack sighs in remorse, "I think I know why. She's still upset about all of us turnin' our back on her. This creature must have turned her into this monster that is consumed by her sufferin'."
"In other words, Sunset became a monster not just because of this Nihilego… but because of all of us not being there when she needed us the most," Rarity adds.
"How could we ever doubt her?" Fluttershy whimper.
Then Apple Bloom asks, "And how are we going to get her out?"
"We need to weak the Nihilego until the bond between Sunset and the pokemon is broken," Gladion says.
Lillie holds out the beast ball, "And we need to capture it in this after separating them."
"Then what are we waiting for! Let's save Sunset… before that think blasted us!" Pinkie says in a screaming tone.
Just then the creature begin to spinning fast, and zooms right at them.
Rainbow screams, "Hit the deck!"
Everyone are able to run and duck out of the spinning pokemon's way. They look to see the creature has stop, and looking at them in anger.
Sunset screams with rage, "I told you to leave! NOW!"
Just as her anger begin to rise, tears are beginning to shed from her face. Twilight and the other girls can see Sunset crying meaning she is suffering more by the minute.
Twilight begin to worry, "Poor Sunset, how did that thing got to her."
"It must have happened after she yelled at us," Rainbow admits in guilt.
Twilight becomes shocked to hear this, "She yelled at you?!"
"I'm afraid so. She was mad at us for thinking she's Anon-A-Miss, and said that we weren't friends with her anymore. She… she even said that we were never her friends to being with," Applejack explains.
She begin to show remorse, "And honestly… I don't blame her for thinkin' that. After she changed, at the Battle of the Bands, and now, we weren't acting like friends to her."
"We'll do anything to make up with Sunset, we just don't know how," Rarity adds.
"And we don't think the magic will work without Sunset with us," Fluttershy says in concern.
Twilight sighs, "I guess we all owe Sunset an apology. I should have come sooner, but there was trouble in Canterlot at the time. I should have been more worried about Sunset more."
"It's okay darling, we understand that you're a princess and has your own responsibilities," Rarity says.
"Yeah. We can't rely on you to solve our problem," Rainbow adds.
Then Pinkie says with a sad look, "Sadly, this is one problem that will be impossible to fix."
"But you have to at least try," Mallow says.
"She's right. Sunset needs you, and she can really use your friendship right about now," Ash says.
Twilight and the five girls look at each other, then nod their heads with smiles and determination on their faces.
"You're right. Sunset needs us. She needs up and friendship more than ever," Twilight says.
"Let's do it! Pinkie shouts.
The get up and face the powerful ultra beast with the girl inside.
Ash shouts, "Pikachu, use thunderbolt!"
Pikachu runs as it admits yellow electricity from its body. The blast at Sunset. But doesn't put it done, she then throws red crystals.
"Steenee, use double slap on those gems! Then use magical leaf!" Mallow commands.
Steene jumps and uses its' big leaves to whack the crystals one by one. Steebee then creatures a green circle and stream of leafs hit the other gems and the tentacles.
Then Lillie shouts, "Snowy, use powder snow!"
"Use zig zag, Togedemaru!" Sophocles adds.
Then Kiawe says, "Use flamethrower, Turtonator!
"Silvally, use crush claw!" Gladion adds.
"Popplio, use aqua jet!" Lana adds.
One by one, each of the pokemon perform their attack, and able to hit Sunset or the attacks she is throwing. Twilight and the Canterlot High girls are astonished to see the powerful attacks that are being performed. However, at the same time, they fear from Sunset who is getting hit by the attack, even though it's pokemon they're striking at.
Just then, she begin to spin faster and faster. The spin creates a powerful wind that is trying to send everyone away. The trainers, the CHS students, the princess, and the pokemon are doing their best to hang on, but end up being blown into the snow. When the wind is gone. Everyone look to see the ultra beast pokemon is still standing, and Sunset is still trapped inside.
Rainbow groans, "Is there no way to stop this?"
"None of the pokemon's attacks are working on it," Kiawe says.
"How are we going to stop it?" Lillie asks in fear.
Before any questions can be asked, the ground began to shake and it's moving the park. Everyone turn to see the Nihilego is up to something. The creature then creates a pillar like mountain. As it begins to grow, it begin to creature crystals on the side and the bottom.
Applejack shockly shouts, "She's trying to seal us out."
"What can we do?" Twilight asks in a panic.
"I don't know, but we got to do something," Ash answers.
Pinkie looks around, noticing a few are missing, "By the way, where's The Crusaders?"
The others are looking around to see that Apple Bloom, Sweetie Belle, and Scootaloo are not with them.
"Where they go?" Fluttershy asks.
Rainbow looks ahead, and shows a scared look, "Don't look now, but I see them heading towards Sunset still trapped in that thing!"
Everyone gasp and look to see the young Crusaders are running towards Sunset. Twilight and the girls begin to chase after them.
Applejack shouts as she chases her sister, "Apple Bloom, what in the sam hill are you doin'?!"
"I'm sorry Applejack, but there's something I really need to tell you, especially to Sunset," Apple Bloom shouts back.
"This is something we have to do, try to understand," Sweetie Belle adds.
"What is it that will end up putting you three endanger like that?!" Twilight asks.
"You'll know when we tell her," Scootaloo answers.
Rarity worriedly shouts, "Sweetie Belle, you can't do this!"
"But we have to!" Sweetie Bell protests.
"Well, it better be good because Sunset knows we're here," Pinkie replies, pointing her finger in response.
The girls stop in their tracks to see they are at the bottom of her look up to see Sunset on the top. The mountain is about 20 feet tall, and is covered with spiky crystals all around.
Sunset angrily shouts, "I thought I told you to go away!"
"Not without you Sunset," Applejack protests.
"Why?" Sunset angrily shouts.
"Because we're your friends. We're here to help you," Twilight answers in concern.
Sunset stops to see that Twilight has arrived.
Sunset shakes her head, "No! If you were my friends they wouldn't have abandon me, and accuse me of something I didn't do! If you were really my friends, you would believe me. Unless I was never your friend to begin with!"
"That's not true Sunset," Applejack exclaim.
"We're sorry we did that," Fluttershy adds.
Then Rainbow says, "We should have make sure to check out any option, but we know that you were serious on what you said to us."
"Please Sunset, do settle down, and… separate from the pokemon," Rarity says, trying to be calm about it.
"Pretty please!" Pinkie begs, giving Sunset the puppy eyes.
"I won't! You all left me, you all abandoned me, you all think I'm nothing but a charity case! Friendship is nothing but a lie!" Sunset shouts in tears and rage.
Sunset then begin to create more crystals, and spreading them around the park. Apple Bloom runs over and begin to climb up to reach Sunset. Sweetie Belle and
Finally reaching the top and is able to walk towards Sunset, Apple Bloom shouts, "Sunset, you can't do this!"
"Why not," Sunset firmly asks.
"Because, I'm the reason why you've became the most hated student in school! I'm the one who started all this by posing my sister's nickname! I'm Anon-A-Miss!" Apple Bloom loudly admits.
Twilight, the girls, Ash and his friends gasp in shock to hear Apple Bloom's confession. Sunset stops her sadness and rage. She then looks down to see the sorrow and remorse in Apple Bloom's eyes.
Apple Bloom admits, "I'm sorry, I caused you so much pain. I never wanted any of this to happen. What's worse… I did all of this out of petty jealousy and a stupid grudge."
"But… why did you feel that way," Sunset slowly asks.
Apple Bloom sigh, "I guess a part of me didn't like how Applejack is being with her friends and not family during the holiday. I sometimes think that you still got off easy. The night you all were at Pinkie and after talking to y'all, I created the account about Applejack's nickname and made it look like you did it."
Sweetie Belle and Scootaloo is able to make it to the top and join Sunset.
Sweetie Belle shares her story, "I'm sorry too, I was also involved in this. When Apple Bloom told me what she did, I understood her and I felt left out at your sleepover at my house. So that night, I snuck into her room and took your phone. Then I posted the pictures you took on Anon-A-Miss' account so you will be singled out."
Hearing all of this, Twilight and the girls being to climb up the mountain to confront Sunset and the Crusaders. Meanwhile Ash who is riding on Solgaleo, and Gladion riding on Silvally come along with them, and the rest stay there.
As they climb up, Scootaloo explains, "I'm involved with this too. I took Rainbow's test during soccer and posted it, but Anon-A-Miss got out of hand. People begging to share their secrets and we posted all of them. We never wanted any of this to happen. We never wanted you to suffer so much."
"Please don't be mad at our sisters," Sweetie Belle begs.
"If there's anyone you should be mad at, it's us," Apple Bloom adds.
"Yeah. Even though you'll never forgive us, at least be friends with Rainbow and the others again. We're so so sorry," Scootaloo adds, trying her best not to cry.
Sunset is shocked to hear what the girls are saying and the guilt on their faces. Sunset is starting to feel… different like she is starting to regain her senses.
Just then Rarity's voice appear in remorse, "That maybe Sweetie Belle, but sadly… we're also to blame for all this."
Sunset and the Crusaders look to see Twilight and the girls on the top of the mountain too.
Apple Bloom disagrees, "But we were the reason all of this happen. We wanted to tear your friendship apart. We were no better than the old Sunset when she did it to you."
"True apple Bloom, what you and the girls did was wrong. But… we allow Anon-A-Miss post to cloud our judgement, and allow it to break our friendship apart," Applejack says, walkingto her sister.
"She's right. We weren't willing to listen to Sunset. We let our anger and embarrassment get in the way, but we're not going to anymore," Rainbow replies.
Fluttershy comes over with tears, "Sunset, we know that want we did was unforgivable, but we can only hope you want to be our friends again. EVen if you don't want to be our friend… we can only hope you forgive us."
"We just want you back Sunset. And I'll make sure to throw you one of my special Pinkie Pie party after this," Pinkie adds.
Then Twilight comes in, "Sunset, I know you are very hurt and what the girls have done is wrong. But don't you see, they are willing to what they can to fix their friendship with you. I know how hurt it was when your friend didn't give you the benefit of the doubt, but we can go through it."
"Will you give us another chance in friendship?" Twilight asks, holding her hand out to Sunset.
Sunset eyes changes back to their normal state. Hearing her friends, Princess Twilight, and The Crusader's remorse and apology is able to reach her. Tears are starting to come out of Sunset's eyes, and begin to remember all the time they have since she's reformed. How she and her friends have gone many obstacles for their friendship. Now, Sunset can see that they see the errors of their ways, but also show how they truly care for her. Wanting to be with her friends again, Sunset begin to bring her hand forward towards Princess Twilight. Everyone smiles, especially Princess Twilight and the girls to see Sunset is finally waking up from her corruption.
Twilight smiles, "Sunset."
But before Sunset can fully reach out to the girls, crimson coils wraps around her hand Sunset becomes stunned and tries to remove her hand, but she can't move her body. Everyone gasp in shock to see what is happening. The red crimson and gold yellow hair begin to extend and cover Sunset out.
Sunset begins to cry, "No… Twilight… Girls… Help me!"
Sunset ends up being fully consumed by the red and yellow hair.
"Sunset!" Twilight screams, running towards Sunset to help.
Before she can reach Sunset, Gladion grabs Twilight by the arm, "You can't, it's too dangerous!"
"But… that thing consumed Sunset!" Twilight reacts with fear.
The Nihilego then creates a giant crystal wall and use it to cover herself. Everyone begin to step back from the crystal fortress. Ash help the girls on to Solgaleo and Silvally so they can get off the mountain and escape.
Shedding tears, and try to break from Gladion grasp, Twilight screams, "Sunset… no!"
"You have to get away from here," Gladion says.
Twilight finally agrees, and runs with Gladion. Once everyone is on the two pokemon, they carry the young teens down the mountain, and everyone begin to run to a farther distance from the area.
When everyone reach a far distance, the three groups of friends are stunned to see a giant crystal fortress with crystal spikes coming up. They can tell that this is more serious than they think. Sunset is fully corrupted by the monster, and now has created a giant fortress to protect itself. They need to break Sunset free, and fast, before Sunset is lost forever.
