Author's note: I don't own Miraculous ladybug, all rights go to Zagtoon. This story is inspired by ABC's "Once Upon A Time," so I suggest you watch that. Please note that this is only my second story, please leave me feedback if you think I need it.
It was a normal akuma attack until Hawk moth himself showed up! After they de-evilized another villain he was furious and tired of losing. Marinette just de-transformed and was heading home when she saw Hawkmoth on top of the Eiffel tower!
"Oh no! Tikki, I have to transform!", She said.
"Let's go, Marinette!", Whispered Tikki.
"Got it! Tikki, Spot's on!" She transformed into Ladybug and went to the Eiffel tower to fight him. 'What do I do? It's not like I can de-evilize him.' She thought to herself. 'Oh wait, I know'
"Lucky Charm!" She yelled and another yo-yo flew at her. 'Wait, I have a magic yo-yo. Why do I need a normal one?' she thought. She was thinking of what to do and out of nowhere Hawk Moth came and grabbed her earrings! She de-transformed but for some reason her lucky charm didn't disappear. 'So that's what that was for.' she thought. Hawkmoth had her miraculous and all she could do was wait until Cat Noir showed up. Meanwhile, Adrien just got home and his dad wasn't there (obviously). He went to his room anyway. He checked the news and saw something he thought he would never see, Hawkmoth on top of the Eiffel tower! He looked closer and saw him holding Ladybug's miraculous!
"Oh, no! Plagg, your cheese is going to have to wait!", He said. "What's so important that I have to miss a cheese break?", Asked Plagg annoyed.
"Hawk Moth is on the Eiffel tower with Ladybug's miraculous! Wait, Marinette is there too! I have to go before she gets hurt!", Said Adrien.
"And you say she's just a friend."
"Shut up, Plagg!"
"Well she is more than a friend, she's your partner.", Said Plagg.
"Wait, Marinette is Ladybug?", Asked Adrien.
"Yep, but you got to go!",yelled Plagg.
"Okay, no need to yell. Plagg, Claws out!" Adrien transformed into Cat Noir and ran to fight Hawkmoth!
Meanwhile, Marinette was still using the yo-yo from her Lucky charm to try and snatch Halkmoth's Miraculous from him. She couldn't do much because the yo-yo was not Magic. 'Crap, what am I going to do now?', she thought. And then Cat Noir finally showed up.
"What took you so long?", Marinette asked.
"I just saw the news, M'lady.", Cat Noir said.
"M'lady? How did you find out?", Asked Marinette.
"My kwami kinda blurted it out", he said. "I can't do much with this, it's not Magic, could you help?",asked Marinette, showing him the lucky charm.
"Of course. Cataclysm!", He yelled and put his palm on the Eiffel tower, and it burned to the ground. Hawkmoth dropped Marinette's miraculous and she tried to grab them back but Hawkmoth got to them first. *Beep beep* Cat Noir was about to transform back! He was distracted by his miraculous for a moment and Hawkmoth took it as an opportunity to take it. Hawkmoth got it and Cat Noir transformed back into Adrien.
"Adrien?!", Asked Marinette and Hawk moth at the same time.
"Why do you care who I am, Halkmoth?", Asked Adrien harshly.
"Dark wings, fall!" Yelled Hawkmoth, he de-transformed into Gabriel Agreste.
"Father?! Why are you doing this?!"
"I'm doing this for your mother, Adrien. I need the miraculouses (or Miraculous, it's not really clear) so that I can bring her back!"
"There's always a price! If you ask to bring her back someone will die! For all you know that could be Adrien'' Warned Marinette.
"She's right father! You can't do this!", Yelled Adrien.
"If you won't let me do this there is only one way to keep my son and have my wife.", Gabriel said, "I'm sorry son" He used the miraculouses to bring Emily back, killing someone in the process then he cast a curse, and brought everyone to a new world with new memories.
