It was a normal day at the Louvre Museum. The class was on a field trip to gaze upon the new exhibits. The tour guide stopped and turned to them.

"Now, everyone pair up and meet me back here in 30 minutes."
Marinette and Alya wandered around at some of them.

Alya was taking photos of ladybug resembling relics, "This is so going to be in the blog."
"I thought the blog was dedicated to Ladybug."
"It is. We know about her and the Pharaohs, so what if these are connected to her. Maybe they are connected to her."
Marinette chuckled at her hypothesis.

Meanwhile, Adrien and Nino wandered off to another part of the exhibit.
"Dude, this just keeps getting better and better. The only thing that would ruin my day is an Akumatized villain coming along.
Suddenly, there was a shout, a familiar "Adrikins."
Nino watched as Chloe squeezed Adrien, "I stand corrected."

After 27 more minutes, the class came back to the rendezvous point.
"I hope everyone had a good look. Now let's go-"
A portal grew right behind him. He cowardly stepped away slowly.

A figure stepped out, a girl in a ladybug costume and a backpack slowly came out before it closed.

The class stared, the girl looked at her surrounding, "They couldn't have sent me here when it was night? This is just-"
She grasped her stomach, then clasped her hands to her mouth, running to the nearest garbage bin.

After she... let's not go there... Anyway, she looked back at the class, not realising her mask fell off when she was at the bin.
To their shock, the girl looked almost exactly like Marinette, only her pigtails were shorter.

When she noticed she was mask-less, she ran back to the bin.
Unfortunately, it was no point to hide it anymore, so she introduced herself properly,
"Okay, my name is Marietta Dupain and I'm from an alternate universe where I'm a normal girl by day, Ladybug by night."

Some of the class bought it, others wanted proof.
"Are you kidding me? I look like your Marietta."
"Actually, my name is Marinette."

Alya was filming her, asking her about how she got her powers, her age, if there is a Cat Noir in her universe.
There were some thing she didn't get, like the fact she had no powers at all.

As for the Cat Noir question, "I did see some guy in a cat costume when I on the rooftops."
"What's he like?"
"I don't know. What I do know, is he's some guy who's, like, 60... or was that over? It was hard to tell 'cuz he was always in the shadows."

Adrien couldn't believe that the Cat Noir she's from could be an old man.
Marinette was in disbelief that she was her of another world. More importantly, Marietta was also Ladybug.
If there were more worlds like that, people will know who Ladybug is.

When someone asked why Marietta was here, she quickly remembered, "Oh, right. I'm here to warn this world's heroes that a lajukanized army from an evil world is coming here."
Adrien looked at her with a confused face, "You mean an Akumatized army?"
"Gah, I knew 'lajuka' didn't sound right. Thanks, Hot stuff."

Marinette blushed, remembering the time she had to steal his phone.

"Anyway, I sent here to help the good guys stop the baddies."
Alya approached her, still filming, "And how are you going to do that if you don't have powers."
Marietta had a moment of silence, before answering, "Huh, I probably should've asked before hurling myself in."

Everyone was speechless, she shrugged, "Oh well. So, where am I gonna sleep tonight?"
Marinette thought her to be unbelievable, "There is an army coming, and you're asking where to sleep tonight?"


The class agreed to keep the whole 'Marietta' thing a secret.

And at the end of the trip, Marietta changed into her casual clothes:
A pink sleeveless shirt, white stockings with pink stripes and a white skirt.

Marinette and Marietta went to the bakery. Her parents were nice enough to let her stay for a while.

When they went to her room, Marinette got to know more about her counterpart,
She found out that the only family she had was her father and that she doesn't know any Agrestes.

"What?! How can you not know the Agrestes?"
She shrugged, "Guess I spent my time studying."

Finally, it was time to call it a night. Marietta agreed to sleep on the sofa.

When she was sound asleep, she and Tikki watched as questions needed to be answered. When she asked about the alternate world Marietta was from, Tikki only stared as she answered, "It could be possible that the theory of the Multiverse could be real. I sensed it, she is you."

There was so much to think about, but she decided to sleep on it. Literally and figuratively.


Another day, she's back at school.

There were some difficulties to get 'herself' as a temporary student, but it worked out in the end.

As they went in the homeroom, Alya ran to them in excitement and panic,
"Girl, did you hear what happened last night? Ladybug robbed a jewellery store."

There's no way, it must have been an Akuma trying to frame her, like the Copycat incident.
Alya grinned, "Don't worry, I know it's not the real Ladybug. I'm sure she'll catch the imposter... And think I know who it is."
She stared at Marietta, closing in to her face. "Um, what are you doing."
"When you came here, you said you were Ladybug by night."
She was offended, "And you think it's me? I warned you about the evil army."

Alya still wasn't convince, "What if that was a lie so you can steal whatever you want?"
She threw her arms in disbelief, then went to the back of the classroom and took her seat.

Adrien was in deep thought about the Ladybug robbery. After eavesdropping on Alya, it makes some sense.
Even if Marietta was the culprit, why would she cross worlds to do so?


Night fell, Marietta snuck out seeing that her doppelganger was 'asleep'.

When she was out of sight, Marinette sat up, "Tikki, I'm having doubts about trusting her. Tikki, Spots On."

And there she was, leaping over rooftops, arriving to an individual in the shadows. Ladybug kept her distance, but she was close enough to eavesdrop.
"The beacons are in place, now for your part of the deal."

The silhouette looked exactly like Cat Noir, speaking of which, he accidentally surprised her with a light hand on the shoulder.
The scream gave them away, the Cat Noir Double sped off, leaving Marietta to fight them.

"Marietta Dupain, what are you doing and who was that?"
She smirked and scoffed, "I made a deal with a handsome devil named 'Cat Blanc'."

Cat Noir groaned, now that there's another copycat. Ladybug stood in shock to see her double like this.
"How could you do this? You said you were a hero by night."
"No, I said I am Ladybug by night. Ladybug, The Mini Menace!"

Cat Noir mentally slapped himself back to reality, "So everything you said were lies?"
She chuckled, "What I said about the army was true, that I have no powers is true, and the part where I'm from an alternate universe is 100% genuine."

He brought his staff out, "Well, I'm feline a little merciful tonight, so why you just purrender now and we might make a deal more clawesome than whatever he offered you."

"One, cut the stupid puns. And two, not a chance, pest. Once, this world is taken, I'll get the car."
She charged at the two, who thought it was stupid for her to help evil for a plain, old car.

Since the Mini Menace didn't have powers, she was easily defeated with a single yo-yo tying her to a pole.


She struggled as the police shoved her in, then declared, "You fools, they will rule your world, and you won't be a part of it!"

They drove off, leaving the duo in the cold air of the night.
"So Milady, shall we search for this 'Cat Blanc' or at least know what we're up against?"

It doesn't make sense, why send someone powerless and end up having her beaten? Unfortunately, she was too tired to think.


On the Eiffel Tower, Cat Blanc met up with the other three. Ladybeetle was furious.
"THIS was your plan?! You idiots, maybe I should have you under my control so you could do things right!"
Miss Fortune greeted the boy in white with a peck on the cheek as she didn't care about what Ladybeetle said.
Now, now, Spikey, no need to get your hair crazy. The beacons are in place, soon the whole army will be able to cross over."
Cat Rogue purred in delight, "Then, let's strike now."

"Uh-uh-uh, let's not get hasty. My kitty has one more errand to do. Isn't that right Kitty?"
He purred, then kiss her hand, "Anything for you, my queen."
