On Melemele Island, we see the adults laying around doing nothing while the children were running about, playing while some try to wake up their parents so they can do something but nothing was working. We then see a van that sells buns and other sweets as we see Meowth and Wobbuffet seeing all the adults not coming over to theie van and buying something.

Meowth: Huh is it me or are these adults ain't doing anything?

Wobbuffet: Wobbuffet.

Meowth: (smirk) Maybe this is a perfect time to capture some pokemon and get out of here. Hey, Jessie, James, let's steal some pokemon!

They were inside the van and not doing anything as they yawn ane laying around inside the van.

James: I'm not in the mood of stealing pokemon right now.

Jessie: (yawn) Yeah, can we do it tomorrow or something?

Meowth: What is wrong with you two, we got work to do!

Suddenly they heard something and look up and they noticed something falling and seconds later it landed on impact as both Wobbuffet and Meowth hold on. Soon they watched as Red Heart slowly get up and turn his head to the two and said.

Red Heart: Yo. Sorry but best you get out of here before things might get messy.

Meowth: (shocked) No need to tell us twice! LET'S GET OUT OF HERE!

Wobbuffet: (shocked) WOBBUFFET!

They hope into the van and they speed off as Red Heart suddenly realised something.

Red Heart: Did that pokemon just spoke!?

Suddenly he was hit by Arfoire as he was sent flying and soon crash into the street and slide onto the floor until he stop. He slowly get  up and look up to see Arfoire landing across from him as Red Heart gets up and said.

Red Heart: Seems like you've gone stronger since the last time we met.

Arfoire: (smirk) Indeed and this time you will not stop me and my plan. Soon I'll take over both worlds and no one will not stop me!

Purple Heart: Hate to break it you but that's not gonna happen!

Purple Heart came to strike at Arfoire but she turned around and block the incoming strike. Then she grabs Purple Heart and tosses her towards Red Heart which he catches her and then both White Heart, Green Heart and Black Heart fly over to her and they battle her. They strike their blows at Arfoire but she blocks the incoming strikes and then flies over them, landing behind them and then fired a blast that sent the trio flying towards Red Heart and Purple Heart.

They land in front of them and get up while Arfoire smirks at them as she swings her spear towards them.

White Heart: This is getting ridiculous! She's too strong.

Red Heart: She maybe strong but we're stronger. We can overwhelm her and take her down.

Green Heart: Agree, we can't allow her take over both worlds.

Black Heart: Right, let's do this!

Purple Heart: (smirk) We won't let this world fall by the likes of you Arfoire.

Then Arfoire starts to chuckle to herself and then tells them.

Arfoire: (smirk) Oh please, even if you defeated me my creature will rip both worlds apart and everyone you ever care for will be gone!

She rushes towards them while they were ready for hee when suddenly a shell hits Arfoire in the guts and sent hee flying as she hits the floor. They were surprised as the shell open to reveal a pokemon as he turn to them.

White Heart: Whose that pokemon?

Green Heart: This might be a wild guess but I believe that Melemele Island guardian Tapu Koko.

Red Heart: Wow!

Then the other three guardians arrived as they flout over them and look down at them as they see them as theie allie. Then Arfoire slowly gets up and glare at them and then shoots a powerful lighting at them.

Arfoire: I will not be defeated by the likes of these pokemon!

Red Heart sees this and immediately gets in front of them and blocks Arfoire's lighting strike. He stood tall as the four Alola guardians stood with him as Red Heart turns to Purple Heart and the others.

Red Heart: Help out Ash and the others. We'll deal with Arfoire.

Purple Heart: Right, be safe.

White Heart: Yeah try not to die on us.

Red Heart: I promise.

Then the four fly away to help out Ash and the others as Y/n and the four Alola Guardians stare at Arfoire as she let out a chuckle and then ask.

Arfoire: (smirk) Do you really think you can stand up against me? I don't know if your a idiot or a fool. I have gone stronger ever since I was brought to this world and now I'm stronger then every as I can defeat you.

Red Heart: Well let me tell you something. No matter how strong you might get, I will not give up because I will keep others safe no matter what. Now enough talk, let's dance!

Red Heart and the four Alola guardians charge towards her while Arfoire smirked and charge towards him and then the two clash blades as the two have a blade lock and then Y/n immediately leap backwards while Arfoire swings hee blade to strike at him but missed but the two clash blades at each other as the two continue their fight. Then the Alola guardians came down and attack Arfoire as she gets hit by them.

She swings hee spear at them which cost them to step back a bit but this gives Red Heart a chance to lift Arfoire up and tossed her across town and land hard in the middle of town.

Arfoire slowly gets up and sees Red Heart rushing towards her so she pick up a car filled with a family inside and she tosses it towards Red Heart. The child in the car cheered while her parents scream a bit in a tired like tone. Red Heart catches the car and gently set it down.

Little boy: (smile) That was awesome! Let's do it again!

Moth and father: (yawn) Maybe later son.

Red Heart rushes towards Arfoire as he pulled out his sword and he strikes and flash at Arfoire. The two lock blades for a bit and then they clash blades as sparks fly out of theie blades as they dual in the middle of town while the Alola Guardians watch them battle.

(Meanwhile)

Ash the others catch up to Lunala who is taking over by Necrozma as the possessed Lunala attacks Nebby with attacks while Nebby try to dodge those attacks.

Mallow: We need to help Nebby before it's too late!

Unzume: (smirk) Well its a good thing you have us to stand up to it. Ready Plutia?

She turn to her only to see Plutia fallen asleep on Kiawe's charizard which they nervously chuckled.

Unzume: Guess it's up to me then, let's do this!

She leaps out of Ash's Garchomp and transformed into Orange Heart as she came up next to Ash, Pikachu and Poiploe.

Orange Heart: (smile) Transformation complete~! Orange Heart ready for battle~!

Lana: (surprised) Amazing, her personality is completely different to her human form.

Mallow: (smile) Aaaww ain't that a cute voice.

Orange Heart: (giggle) Thanks, your too sweat. Now let's save the day!

She flies over and protected Nebby by summons a force field in front of the possessed Lunala and then fired a sonic blast at Lunala, costing it to fly back while Nebby let out a roar. The possessed Lunala gets back and then let out a roar and flies towards them which Orange Heart try to block but Lunala punched through, costing Orange Heart and Nebby to be sent flying back. Then Plutia woke up and sees Orange Heart and Nebby in trouble as she gete up while Kiawe turn to see her awake.

Kiawe: Plutia, glad your awake. Can you transform and help out Orange Heart and Nebby?

Plutia: (smirk) Sure, this would be fun.

A chill went down Kiawe spin and immediately she transform into Iris Heart and fly over and wipes the possessed Lunala as she gets in front of Orange Heart and Nebby.

Iris Heart: (smirk) My My look how mean you are bullying cute Nebby and Orange Heart and possesseda Lunala. I'm gonna enjoy punishing you!

Suddenly she charge towards the possessed Lunala and wipes it with hee wipe over and over again and the two battle while she laughs as she enjoys this while Ash and the others were a shocked and a bit scared.

Sophocles: (scared) No wonder you didn't want Plutia to transform the first time we met.

Orange Heart: (smile) Yep but don't you worry, she only punishes those who are mean to hee good friends.

Ash: Well that's a relief.

Pikachu: Pika.

Soon Iris Heary managed to land a blow to Lunala which cost Necrozma to leave Lunala's body as Lunala opene her eyes as Nebby goes over to Lunala and see that she is alright.

The two turn as Necrozma let out a roar while Purple Heart and the others arrived just in time.

Purple Heart: Seems like you that ultra beast out of Lunala's body.

Orange Heart: (smile) Yep-Yep, all thanks to Iris Heatt!

Iris Heart: (giggle) It was fun. Now, where ie Y/n?

White Heart: Fighting Arfoire but we got this.

Purple Heart: That's right. Let's do this everyone.

They agree and they stood in front of Necrozma as Necrozma was about to attack them until Necrozma stopped and turn to Melemele Island and then flies over there.

White Heart: It's getting away!

Black Heart: Let's go after it!

Ash: Right! Let's go guys!

Pikachu: Pikachu!

(Meanwhile)

Red Heart was sent flying and crash hard inro the beach but he immediately gets up onto his feet ane loos over to see Arfoire walking towards him. She just took down three Alola guardians but Tapu Koko charges towards her but she blocks his attack and then grab him and tossed him away.

He crashed into the wall while Arfoire turn to Face Red Heart only foe him to charge towards her and the tow class blades. They strike blades at each other, dodging their swings and soon ended up in a blade lock.

The two lock blades as the two glare at each other. Then Arfoire smirked and suddenly there was a roar behind Red Heart so he quickly turn and Necrozma appear as it charge up its attack and fired a beam at Red Heart. He blocks the beam and try to hold it and seconds later there was a huge explosion which Purple Heart and the others see ans quickly fly over.

We then see Red Heart on one knee after that attack but he slowly get up and looked up at Necrozma as he smirk underneath his helmet while he ask.

Red Heart: Is that the best you go-

Suddenly something sharp break through his armor and through his chest as he stood there and slowly look down to see a blade from a spear was through his guts as we see Arfoire behind him as she stabbed Red Heart which hee spear as she smirked and then pulled out her spear as Red Heart fell on both knees and grab his wound as he cough while Arfoire walk around him and then stood over him.

Arfoire: (smirk) You can never defeat us Y/n. No one will not stop us.

Then Necrozma grabs Red Heart by the head and them slammed him onto the ground over, over and over until it tosses him across the beach and he land hard onto the ground. Red Heart changes back to his human form with a large wound as blood start to pour out as he cough more but this time blood came out of it as Purple Heart ane the others came over as the six goddess surrounded Y/n.

Purple Heart: Y/n! Stay with us!

Y/n stare at Purple Heart as he was about to say something until he felt like his eyes is getting heavy and then he passes out as he shut his eyes.

White Heart: Damn it is he gone?!

Black Heart: No I think he's unconscious.

Ash and the others were shocked by this and wordy for Y/n while Arfoire laughs and then called out.

Arfoire: (smirk) Now its time we end this once and for all! Necrozma!

Necrozma let's out a roar and then immediately the two of them fuse as they turn but quickly look away as there was a blinding light and soon the light died down and they see Arfoire now fused with Necrozma with Necrozma's arms appear over hee back along with Necrozma's eyes and feels sven more powerful then before.

She let's out a laughter that can be heard over the whole island of Melemele while Y/n lay there unconscious as they have no idea what to do and how they suppose to defeat Arfoire now that she is powerful.
