(quick note: I started this episode before I saw Frozen 2)

Marinette wakes up yelling

"Wow! What's wrong Marinette?" Tikki asks shocked.

"Oh Tikki, I just had a very bad dream..." she replies.

"You want to talk about it?"

"Well, let's just keep it short, something happened with Klara, there was another akumatized person in another world, but I can't remember anything about it... but the akumatized person defeated us and Hawk Moth got our miraculous..." she says.

"That must've been scary..." Tikki says.

"It was, I'm glad that it was just a bad dream,"

"I'm glad too, but you have to get up now, you have to go to school!"

"Yes, you're right Tikki!" Marinette says as she gets up and gets ready to start the day.

Elsa and Anna are fighting beside each other against an army created by Hans.

"Anna,please go back! The guards will be here soon and Hans will be send back." Elsa says.

"No! I want to stay with you, after all this time we shall do everything together!" Anna says. Elsa smiles

"Alright then Anna.."

After a little while the guards still haven't arrived. "We should get back Elsa, the guards aren't here yet, we can't go on like this!" Anna yells..

"No, we can do this, our people need to be safe!" Elsa replies.

"The people won't be safer if you're defeated Elsa!" A soldier attacks Anna from behind. "Anna!" Elsa yells and she blasts ice at the soldier, freezing him. Anna gasps.

"Well, well, well, so you finally started fighting in your monster way..." Hans says, smirking.

"Elsa isn't a monster, you are!" Anna says, frowning

"Suit yourself. It doesn't matter, she already knows she's a monster." Elsa looks down, clearly thinking about Hans's words.

"Come on, take him and let's leave" Hans and the soldiers take the frozen soldier and leave. Anna tries to comfort Elsa.

"No, I need a moment alone, go back to the castle. I'll be there soon."

"But Elsa..." Anna tries to say.

"Please Anna..." Elsa pleads. Anna sighs.

"okay, but please come as soon as possible." Elsa nods and Anna slowly leaves. When Anna is out of sight she sits on the ground.

"Hans is right... I am a monster, I can't rule my kingdom like this...".

"Ah, a queen who thinks she can't be queen, what an incredibly negative emotion!" Hawk Moth says. He makes an akuma while Claudia opens a portal.

"Fly away my little akuma and evilize her!"

Elsa sobs while the akuma approaches and lands in her crown.

"Ice Queen, I am Hawk Moth. They told you that you're a monster and say you're unable to rule. With the power I am giving you you'll be able to rule over as many kingdoms as you want! In return, I want Ladybug and Cat Noir's Miraculous." Hawk Moth says.

"Yes, thank you Hawk Moth" Elsa says transformation?

Klara is walking to her room and drops onto her bed.

"I'm tired, I should probably take a quick nap and-". Ice starts covering the floor, ceiling and walls, stopping Klara from her nap.

"What in the world?!" Klara says as she slowly moves over the ice to look out the window, and she sees that everything has been turned into ice.

"Oh no, I bet another person got akumatized! I have to get Ladybug and Cat Noir!" Klara says as she opens a portal to Paris and goes through.

It's break time in the school and Marinette is having lunch with Alya. Adrien walks past them saying: "Hey Alya, hey Marinette!"

"Hey Adrien" Alya says.

"H-hi Adrien" Marinette stutters. When Adrien is further away Alya turns to Marinette.

"Whoa girl, no 'ugh', 'bleh', 'ay!'?" Alya says. "W-what do you mean?!" Marinette replies.

"Girl, usually whenever Adrien talks to you you immediately freak out! What's going on?" Alya asks.

"Nothing! Really!" Marinette looks away, and notices Klara outside the school running around. "Hey, you can tell me anything, you know?"

"Igottagotothebathroombye!" Marinette yells as she runs away. Alya sighs and smiles. Marinette manages to sneak out of the school and goes into a dark alley.

"Looks like Klara needs our help again," Marinette says.

"Then let's go!" Tikki says.

"Tikki! Spots on!" Marinette quickly transforms into Ladybug and quickly goes over to Klara. "What's wrong Klara?" she asks.

"I think there's another akumatized person, I need your and Cat Noir's help." Klara responds. "okay, I'm ready to help, but Cat..." Ladybug says while calling Cat.

"Cat got your tongue? Leave a message after that beep!"

"I suppose we'll have to wait for him then..."

"Okay, I hope he'll come here soon!" Klara says.

Adrien walks up to Nino, smiling.

"Hey dude!" Nino says.

"Hey Nino!"

"So, what's up?"

"Not much!"

"Oh come on! There's gotta be something!" Nino insists.

"Well... uhm... I-" Adrien starts but Nino's attention is drawn by something.

"Hey look dude! It's Ladybug and that cat girl!"

"What?!" Adrien looks through the window.

"I wonder what happened now, what do you think Ad-" Nino says, but Adrien is already gone. Nino shrugs and walks away. Adrien ran into a dark alley.

"Let's get to it!"

Plagg sighs: "There's never a day that we can rest huh?"

"Plagg! Claws out!" Adrien transforms and quickly runs to Ladybug and Klara.

"What'd I miss?"

Klara explains what happens.

"That definitely sounds like an akumatized person!" Cat Noir says.

"Yes, and we should probably power up our Kwami's with ice powers."

"Do you have a place for us to detransform and power up?" Cat Noir asks Klara, who thinks for a moment.

"Yes, I do!

"Great, then let's hurry!l Klara nods and opens a portal and the three go through. Ladybug gasps. "It's like when mister Candeloro was turned into Frozer, but on a bigger scale!"

Cat Noir looks at castle beside them.

"Wow, whose castle is that?"

"it's mine" Klara says. Ladybug and Cat Noir both stare at her with disbelief.

"Did I forget to mention that? I'm a Queen!"

"Wow, you should really start telling us more things about yourself!"

"Alright, and you two too, okay? Like who you really are!"

"I'm sorry, but no. Our identities are top secret. Or else Hawk Moth could find out who we are." Ladybug says strictly.

"Oh, I understand..."

"So, do we enter your castle then?" Cat Noir asks.

"Yes, you can do your things in a room where no one is in! There should be plenty." They both nod and they make their way inside.

"Most rooms are upstairs. Try slowly going up, the stairs are slippery." They nod and use the yo-yo and Chat's staff to go up and slide to a room.

"Spots off!"

"So, it seems like there's a lot more to Klara that we don't know yet!"

"Yes, but I'm sure we'll figure it out in time!"

"I can't wait for it! It's probably very interesting!"

"Who knows? Are you ready?" Marinette asks. Tikki nods. Marinette takes out her ice macaron.

"Tikki! Power up!" she throws the macaroon up. Tikki eats it and powers up.

"Stalac Tikki! Spots on!" Marinette says.

"Claws in!"

"So, looks like Klara is keeping secrets!"

"Come on Plagg! She is helping us, you can trust her."

"Hmm, we'll see..." Adrien looks a little worried about Plagg, but that's it. Adrien grabs the ice camembert. "Plagg! Power up!" Adrien throws the macaron up. Plagg eats it and powers up. "Plagg Glacier claws out!"

After the transformation they both skate out of their room and down the stairs. Klara looks at them.

"Impressive!"

"Thank you, miss Queen!"

"Okay, so where is that villain?"

"I'm not sure, but I think I know who it is and where she should be!"

"Sounds good enough. lead the way!"

"I will, but before I do that.. I have to explain something. This world is a world where all fairy tales are real and connected to each other."

"Wait, so we are going to battle a fairy tale?!"

"In a way..."

"Well, this should be interesting!"

"So, which character do you expect to have gotten akumatized?" Ladybug asks.

"Well, she just so happened to be an exception... A few aren't officially fairy tales, but they ended up in this world anyway. I suspect that the villain we are looking for is Elsa."

"wait, Elsa as in Elsa of Arendelle?!"

"Yes, that is exactly who I'm talking about! Arendelle is one of the neighbouring kingdoms, so that explains why the ice has come here too!"

"I suppose... Anyways, let's go to Arendelle!!"

After a little while they arrive there, looking around.

"As I expected, everything is frozen here. Look, even the people are frozen!" Klara says.

"Should we go inside of the castle?" Cat Noir asks.

"There's a good chance she is in there!" So they enter the castle.

"Okay, so where do we go?"

"Hmm, she could in her room..."

"Sounds like a good idea to me!" Ladybug says. So they go up to her room, going past frozen staff and soldiers. Eventually they reach Elsa's room. Klara gasps,

"Oh no, Anna!" Klara runs to her. Anna stands in the middle of the room. She is holding her arm out, as if she's desperate to help her sister.

"She even froze her own sister! This is really bad..."

"I wonder what got her akumatized, and why she is doing this." Ladybug says.

"Then we could think about where she would go!" Cat Noir says.

"poor Anna..." Klara sighs

"I'll look in the hallway, to see if she is coming-" Cat Noir says before he is interrupted by Ice Queen.

"Why hello there!"

"back..."Cat Noir says sighing.

"Elsa, stop this, this isn't who you are!"

"Elsa is no more, I am Ice Queen!"

"What do you want Ice Queen?" Ladybug asks, narrowing her eyes.

"My goal is to rule every kingdom! I took so many already! froze so many leaders! but I am missing one, and I am so happy she came to join the others!" Ice Queen fires ice at Klara. Klara gets hit right in the chest and freezes.

"Klara! no!" Cat Noir yells.

"Come on Cat, we gotta get out of here! This room is too small, we can't fight back in here!" Ladybug and Cat try to leave the room, but Ice Queen makes an ice barrier to stop them.

"You aren't getting out of here that easily!"

"Cat Noir!"

"got it, Cataclysm!" he Cataclysms the wall. They both run out.

"no! get back here!" Ice Queen yells as she chases them. Finally, they manage to get outside.

"Lucky Charm!" Ladybug yells. The Lucky Charm is a crown.

"looks like you're gonna play princess, m'lady!" Cat Noir grins. She uses her vision and sees the crown, the castle and Cat.

"no Cat, I already have a one" she points to the ice one on her head.

"you take this one, I've got a plan!"

Cat Noir nods and puts the crown on.

Ice Queen comes out.

"So, you looking for royalty? Look at these then!" Cat Noir says.

"You two? Royalty? No way! Give me the crown!" Ice Queen charges at Cat Noir and blasts ice at him. Cat Noir dodges it while Ladybug chargers at Ice Queen.

"Bad move Ladybug!" Ice Queen charges up an ice blast.

"Hey Ice Queen! Catch!" Cat Noir throws the Lucky Charm at her.

"What?" Ice Queen notices the Lucky Charm and stops her blasts so she can catch it. Then Ladybug quickly takes the crown of her head. "Wait! no!"

Ladybug breaks the crown and the akuma comes out.

"no more evildoing for you little akuma!"

"Time to de-evilize!" she says as she catches the akuma.

"Gotcha" she smiles at the butterfly and lets it go. "Bye little butterfly!"

She takes the Lucky Charm and throws it up while shouting: "Miraculous Ladybug!".

The Miraculous Ladybug frees everyone and melts the ice everywhere. Then Ice Queen turns back into Elsa.

"Pound it!" Ladybug and Cat Noir say.

"Ladybug, Cat Noir, you might've melted Ice Queen, but one day I'll burn you using your own flames!" Hawk Moth says.

"W-what happened?" Elsa asks.

"Elsa!" Anna shouts as she runs to her, followed by Klara.

"Anna!" Elsa says and they hug each other.

"I'm so happy you're back to normal!"

"I'm sorry for what I've done..."

"It's okay... Everything is okay..."

"Good job guys! I knew you could do it!" Klara says to Ladybug and Cat Noir. Cat Noir's ring beeps.

"Hate to cut it short, but we really need to leave." "okay, I'll get you two back" Klara opens a portal.

"thank you for your help," Elsa says to Ladybug and Cat Noir.

"No problem! It's what we do," Ladybug says. The three go through the portal.

"Bye Klara, see you soon!" Cat Noir says before running off. Ladybug's earrings beep.

"I gotta go too, bug out!" Ladybug says and she leaves. Klara waves before opening a new portal and leaving with a smile on her face.
