Author's note: This is my first time writing a fanfic based on Miraculous: Tales of Ladybug & Cat Noir. Thank you to my beta Nina of Fairy Tail. For the sake of this AU Felix and Adrien are twins but the mother never disappeared but died when the twins were very young. Also, my French isn't the greatest so if I have spelled any French words wrongly could you let me know and I'll try and correct them ASAP.

It's morning and two 13-year-old boys are seen getting ready for the day.

"You're so lucky, Felix," said Adrien.

"Why am I so lucky, Adrien?" asked Felix. The two boys in question are twins, but they couldn't be any more different. Felix is the eldest, is 5'10, has pale blond, combed-back hair and light bluish-grey eyes. While the youngest twin, Adrien is 5'2 and has waist-length blond hair and light green eyes and also has a feminine body.

"You go to school like a normal kid, while I'm stuck here like a Disney princess!" shouted Adrien.

"You know why you're forbidden to leave this mansion unless you have a photo shoot, it's Père's rules for you," Felix chided. Suddenly, they heard a knock on a door and entered their father. "Felix, you'll be late for school." warned Gabriel "You need to get dressed."

After a few minutes, the two brothers had finished gotten dressed. Felix was wearing a light grey long-sleeved dress shirt underneath a grey vest, a black tie, dark grey dress pants, and black dress shoes. While the younger twin was wearing a white button-down shirt with an upturned collar and sleeves rolled up above his elbow, which he remains unbuttoned. Underneath, he wears a black shirt with five horizontal stripes around the chest which are coloured, from top to bottom, yellow, olive green, bright green, dark green, and periwinkle. He wears blue jeans and orange sneakers with white laces and a logo of a black butterfly in a circle on the sides.

"Felix, you're starting to look like me more and more every day,"said a very surprised Gabriel which was true seeing as Gabriel is wearing his usual clothing that consists of as a white dress shirt underneath a silver vest with red buttons and a cream-coloured dress jacket, along with a red-and-white striped tie. He also wears red dress pants and white shoes with red laces. On the middle finger of his left hand, he has a silver band ring.

"You better leave now, Felix," scolded Gabriel "Nathalie is waiting in the car ready to take you to school."

After Felix left the dining room to go to school, Gabriel looked at his younger son. He held a strict but loving look in his eyes.

"Adrien, I couldn't help but notice the conversation you had with your twin brother about going to school," Gabriel said, "Why is that?"

"Papa," said Adrien. "I want to live a normal school life, like Felix and I want to make friends, instead of being stuck in the mansion!"

"I'm afraid you can't, my child," explained Gabriel. "Please go back to your room. For your safety, I'll lock your bedroom door as well." Adrien sighed in sadness and left the dining room.

Meanwhile, after being dropped off from school, Felix was trying (and failing) to get away from two annoying girls. One of the girls is named Chloe Bourgeois

"Chloe, why don't you leave me alone for at least a few minutes?!" Felix exclaimed.

"Come on Felix," whined Chloe. "Why don't we eat together at lunchtime?"

Felix looks at Chloe and told her no in a very stern voice. He walked away, leaving a shocked Chloe all on her own.

As Felix was leaving the locker room, he groaned and noticed another girl who was blushing and giggling at him. This girl's name was Marinette Dupain-Cheng and she is half French and half Chinese. She has bluebell eyes and medium-length black hair with blue reflections. She usually wears her hair back in two pigtails. She's wearing a dark grey blazer with rolled up sleeves. The inside of the blazer is lined in white with pink polka dots, and it has black trimming. Underneath, Marinette wears a white T-shirt with black stitching and a flower design below the collar. The design itself has pink flowers and black leaves. She wears pink rolled up jeans and blush pink ballet flats with dark red soles.

"Bonjour Felix." Greeted Marinette. "How are you this morning?"

"Good morning Marinette," greeted back Felix, but instead of using a happy tone like Marinette, his voice sounded very annoyed. But Marinette was obvious to Felix's tone of voice tried to talk to him until the school bell rang in warning and both thirteen years old left the lockers to go their homeroom.

After seven hours and thirty minutes at school, it was time for the students leaving the school grounds, while Felix was waiting for his car ride home, he noticed an elderly man that looked like he has some Chinese descent on him, fell down and dropped his cane. Felix left the steps and helped the elderly man to get back up. The man looks at Felix and thought 'He has a kind and gentle soul, he will become Cat Noir.'

"Thank you," said the grateful, elderly man. "My name is Wang Fu."

'So he is Chinese,' thought Felix. "You're welcome, Monsieur Fu," Felix replied. While Felix was talking to Wang Fu, he heard a car horn and noticed it was Nathalie. Felix bowed in respect to Wang Fu and entered the car and officially left the school grounds.

After a few minutes drive, Felix and Nathalie arrived at the mansion. The mansion itself was four - storeys tall and had a basement. Outside of the mansion, the colour theme was tan and cream except for the right side of the mansion, however, the roof itself has black shingles. At the entrance of the mansion, there was a gate that stops anyone from entering and seeing the residents' rooms (mostly Adrien's room), but the gate didn't stop people from seeing Felix's room.

Felix and Nathalie entered the mansion and saw Gabriel standing at the top of the stairs.

"How was school, my son?" asked Gabriel.

"It went well, father, apart from Chloe and a girl named Marinette annoying me," Felix answered. "How was your day?"

"Good son." Replied the twins' father, "But I had to lock your brother in his room, in case he left the mansion without me knowing, however, you can go and see him, I just let the door open."

Felix nodding to his father in thanks and went to his brother's room. As Felix entered Adrien's room he noticed Adrien lying on his double bed, very upset. Adrien's room was different compared to Felix's own bedroom. As Adrien's room is designed specifically for unisex.

While Felix's room was designed more of a boy's theme such as such as his fencing trophies, a double bed and a staircase that lead to another section of the room. (Think of Adrien's room in the show).

"I heard from Père that you wanted to go to school and you would've left the mansion", scolded Felix. However, Felix couldn't continue until both of them heard a scream. Felix and Adrien went to the window and saw the commotion.

"Adrien, stay here!" Commanded Felix, and without warning left Adrien's room.

As Felix entered his bedroom, the first thing he saw was a hexagon shaped jewellery box. He opened it, and suddenly there was a bright light and came out a creature. This creature was 4 inches tall. He has a large head and small body and his appearance were very cat-like; having cat ears, a tail, two cat incisors, and green cat-like eyes, along with one whisker on his forehead and one dark blue whisker on each cheek. The insides of his mouth was purple.

"Hello, my name is Plagg and I'm the Demi-god of Destruction. I can give my wearer the power to transform into a superhero cat." However, as Plagg tried to explain, how Felix can transform and such other things, all Felix could think of is how to protect his brother from the stone creature that is destroying Paris.

"I'm sorry," Felix interrupted while Plagg was still explaining things. "How can I transform into this superhero?"

"That's easy!" Exclaimed Plagg, "all you need to say is to say 'Plagg Claws Out' while wearing the ring."

Felix looks at Plagg and quickly puts the ring on and shouted the transformation spell and left the mansion in haste.

At the Eiffel Tower, Cat Noir saw a young woman fighting, as he neared the battlefield he noticed the women in question was wearing a red skin-tight bodysuit covered in black spots and with a black collar. But Felix noticed that her suit was made out of indestructible fabric. He also noticed some kind of a yo-yo around her hips with a red string. On her face was a red mask with five black spots that are in a symmetrical design, and the waterlines of her eyes are black. Cat Noir also noticed that her earrings are red with five black spots in a quincunx pattern and the bands holding her hair back become red ribbons, resembling a ladybug's wings when it's flying. Felix went to this other superhero and introduced himself as Cat Noir.

"My name is Ladybug." The battle ended but there's one thing that Ladybug and Cat Noir didn't do, they didn't purify the butterfly that had came out of the paper.

Meanwhile, the evil mastermind of all of this laughed and knew that this wasn't the end of his beloved Akuma.

Author's note 2: I hope you enjoyed the first chapter. I'm sorry about the fight scene between the Stoneheart Akuma and Ladybug and Cat Noir but I didn't know how to describe it very well, but I did try my best. At the bottom of this author's note, I did translation and a glossary. .
