Until then, hope you all enjoy this one!

Earth-101915 - Paris, France

It was late at night in Paris, around midnight. The streets were empty with no crowds of people walking about. Even France's own superheroes Ladybug and Cat Noir were not around the area. Even since Shadowmoth had been defeated, things had been a bit relatively quiet.

Save for the occasional bank robbery or a wannabe villain. As well as more importantly, the supposed disappearance of Chloé Bourgeois, not knowing she had joined the Cult of Skarro-working for the Daleks.

Despite that, France seemed to be at peace.

But underneath the Effifel Tower, a barrage of lightning bolts materialized out of nowhere; connecting to and Ricochet off the pillars. The winds blew fiercely with trash cans knocked down and tree branches catching on fire.

Finally after a moment of chaos, a portal opened to reveal a young man in a gray leather blazer jacket, fingerless leather gloves, a gray vest with a Navy blue tie underneath, a gray pinstripe pants suit and black boots with goggles around his neck and slick light brown hair with a bit of a Navy blue streak to match his tie.

He stumbled out of the portal but regained his footing and composure. He breathed heavily as if he had just been underwater.

The young man turned to look at the portal-mere moments before it closed and everything else ceased immediately. Everything was quiet as it was before.

The young man groaned a bit as he turned his neck side to side, all while his neck made a cracking sound.

"Oh!" He groaned. "Multiversal trips can give me a crick in the neck!"

"I knew I should invest more in that random TARDIS left over from the Time War I found ten trips ago!" He added before taking a deep breath. "Next time though."

The young man looked back and forth in confusion.

"Where am I?" He asked a loud.

He then realized he was underneath a structure and stepped out of it to see what it was. And to his pleasure and astonishment; it was the Effifel Tower.

"Yes!" He clasped his hands in satisfaction. "Now only if I have proper confirmation that I'm in the right universe-"

A newspaper flew right into his face and snatched it off his face in an irritable manner.

The young man then adjusted his tie back in place before looking at the newspaper.

With an evil grin on his face.

The young man saw on the front page Ladybug and Cat Noir running over rooftops.

"Excellent!" He exclaimed in excitement. "Ladybug and Cat Noir, which means I can still acquire their Miraculouses."

A beep was suddenly heard and the young man checked his pocket watch, which was in the pocket of his vest.

Opening it, he saw a monster with something of a black crystallized body with hints of silver and some Navy blue.

"We better have gone to the right universe, Heckyl!" The monster bemoaned in a growling manner.

"Oh I can assure you, Snide." Heckyl responded with a grin. "We are here!"

"Then let's go after Ladybug and Cat Noir while we still have a chance!" Snide exclaimed.

"Patience, my grouchy friend!" Heckyl then responded irritably. "And you need to learn it! For I am currently formulating plans to get what I want and soon you'll get your fight."

"You better!" Snide snarled.

Heckyl then closed the pocket watch and placed it back in his pocket.

"He is so impetulant!" Heckyl groaned in annoyance as he rolled his eyes and walked away.

Elsewhere, at an abandoned factory, the variant of the Predacon leader Megatron met with his superiors who appeared via holograms.

He sat in a metallic armchair which he managed to bring from his ship the Nemesis with his fingers folded as he sat with much interest.

"The trip to Earth-101915 was undoubtedly a success, I take it?" The War Monger Megatron asked.

"Thankfully so." The Predacon Megatron said, satisfied. "And I am very eager to complete my assignment."

"Considering the Miraculouses are powerful artifacts, Number One must think highly of you enough to task you to destroy them." Megatron of Earth-112910 said, feeling a bit impressed.

"How can he not?" Predacon Megatron said in a smug fashion. "After all, I won the Beast Wars in my universe. Yes!"

"Don't get overconfident however." Megatron of Earth-122607 warned his colleague.

"I can assure you, this Ladybug and Cat Noir have no possible chance of overcoming me." Predacon Megatron said.

"Make sure they don't." The female Megatron variant said.

"These... superheroes," The Mad Scientist Megatron said the word with disgust. "Are like annoying pests. They're very persistent in winning."

"Make sure when you make your wish as this Shadowmoth apparently did, to destroy the Miraculouses." Megatron X1 said before grinning. "Which would give all Decepticons and Predacons the advantage to conquer this universe."

"Nothing will stand in my way, I assure you... Yes." Predacon Megatron said.

"Make sure of that!" War Monger Megatron responded. "Meeting adjourned!"

With that, the holograms dematerialized.

"This Ladybug and Cat Noir are mere infants." Predacon Megatron said to himself. "Children who somehow acquired the powers of Gods."

Predacon Megatron then grinned.

"The advantage I have is they haven't met me and know what I'm capable of."

He then softly chuckled to himself.

The Predacon leader stood up from his chair with his hands behind his back as he approached his troops in a militaristic fashion.

The Predacons, consisting of Blackarachnia, Inferno, Waspinator, Iguanus, Spittor, Razorclaw, Rampage, Scourge, Injector and Sky Shadow, stood in line like soldiers as they listened to their leader.

"My dear Predacons," Predacon Megatron began. "We have a golden opportunity to win another kind of war."

"A war against persistent inferior lifeforms." He continued on. "But if we can destroy the Maximals, the Predacons can destroy these so-called superheroes. And we will triumph once again!"

"But be warned..." He gravely warned his troops. "I do not and will not tolerate traitors. Remember what happened to Tarantulas... Yes..."

Each Predacon shuttered. All of them recalling his brutal death at the hands of the Predacon leader.

"Then it's settled!" Predacon Megatron said. "We will begin our strike tomorrow!"

The Predacons cheered and roared in anticipation. All except one, who was brooding by the windows with his arms crossed; Dinobot. He stared through the window with an expression of melancholy. Internally debating as to how the outcome of the Predacon victory turned out and why it felt so much without honor. And why should he be ordered to hurt children who would not have the experience of being in war.

Elsewhere...

In another area, another block, the streets were quiet at night as ever. That was, until a bright portal opened.

Stepping out was a woman in a purple dress with silver armor and boots with big, curly raven hair and a golden headpiece.

She had a curious expression on her face as she looked around her surroundings with much interest.

"Looks no different than any version of Midguard." The woman said. "But I think I can have fun with this."

"For soon, this universe will belong to Karnilla." She added a grim tone to her voice.

Suddenly, The Queen of the Norns spotted a figure jumping rooftop to rooftop. Karnilla looked at the figure with curiosity.

"Hmm..." She curled her lips with intrigue.

The Asgardian woman of Earth-030165 walked down the road discreetly in order to follow her. As she began to walk however, she stepped on a newspaper. One she quickly took notice of.

She picked it up to see an image of Miraculous Ladybug and Cat Noir posing for a photo.

"Very curious..." The Asgardian said to herself.

Just as she began to walk down further after a couple of minutes, she heard a noise. The Queen of the Norns turned around to see the sound came from a police siren as a police car drove by in front of her.

In response, Karnilla raised her hand and from the pall of her hand, she fired a magic bolt at the vehicle; promptly destroying the vehicle-causing it to explode and kill the two police officers inside.

"Humph. Mortals." Karnilla scoffed.

Because the explosion was far away, the mysterious figure, Ladybug, could not hear it as she finally reached her home.

With a flash as she entered through the window to her room, she transformed back into Marinette Dupain-Cheng.

"There didn't seem to be any odd activity." Marinette said to Tikki, the Kwami who gave her the Miraculous that allowed her to transform into Miraculous Ladybug.

"It seems things have calmed down since Shadowmoth." Tikki said.

"At least save for the occasional bank robbery." Marinette added for her.

"I'm just worried it's gotten too quiet that someone or something else will come when we least expect it." Tikki said out of concern.

"I don't want to worry too much." Marinette said. "Heck, I would even want to say you worry too much."

She them added, "But at the same time, what if you're right?"

"I don't want to worry you too much, I'm sorry." Tikki apologized. "It's just sometimes we need to be aware of whoever else could come and take his place. Filling a void essentially."

"Let's at least hope it won't come down to somebody worse." Marinette said before yawning.

"Although right now, I'd like to get some sleep and worry later."

"Good idea." Tikki concurred as she curled up on one side of Marinette's bed.

Marinette herself did not even bother changing into her pajamas. She was that exhausted from patrolling that she may as well crash for the night as she went under the covers.

'Still, I really hope there's nobody worse...' Marinette thought to herself as sleep began to take over her eyes.

Outside however, Karnilla ominously stared at the Tom Sabine Boulangerie Patisserie, the bakery that was also home to the Dupain-Cheng family.

The Asgardian had managed to follow Ladybug through the night without the superhero herself or anyone else noticing. The Queen of the Norns stared at the place with intrigue on her face.

"What are you hiding, child?" Karnilla asked softly yet aloud. "I sense something powerful… and I want it."

With that, Karnilla walked away with the intent of fighting another time.

With such new threats with more power and more dangerous than Shadowmoth, Paris was in more danger than before.

For Miraculous Ladybug and Cat Noir, their greatest battles have just begun.

Author's Notes:

Behind the scenes stuff, of course.

- Basically I decided to repeat the pattern I did for the stuff with W.I.T.C.H. regarding Agatha Harkness/Mysterio, Transformers Animated Decepticons and the War Master and do three different villains converging in another universe, this time with Miraculous Ladybug and soon enough, Jackie Chan Adventures where I'll introduce two more villains joining Sylvie to complete the Trifecta of threats.

And really, a war between three villains in those three universes is bound to happen.

- The inspiration for including Heckyl and another Power Rangers villain for another Addendum, was the recent History of Power Rangers video on Cosmic Fury by Linkara.

That season had Heckyl come back and I decided to include him, or at least a variant of him when he stayed a villain. Especially as it made things easy for me and he just seems so fun to write.

- The idea of Heckyl wanting the Miraculouses to collect was something I discussed on the Infinity Crisis discord group chat. Sentinel of Stories suggested he'd be a Collector type that I decided to roll with it.

- Reminder that this is the Beast Wars Megatron who is a variant that won the Beast Wars.

And in his case, he's something of an anomaly as in regards to his beast nodes, he can transform into his season one and season two Transmetal beast forms. Which I admit, it's the result of indecisiveness where in the timeline is the variant from.

- Iguanus, Spittor, Razorclaw, Scourge, Injector and Sky Shadow are characters who never appeared in the show but had toys. I even owned the first two as a kid.

But basically I decided to include them for fun and give them some representation. I will say, three of them are genderbent as with the Decepticons who are with War Monger Megatron, I wanted to include gender diversity. I wanted a few female characters to not make it a sausage fest.

So Spittor (who resembles the Transmetal beast mode) and Scourge are female.

- Dinobot is the same character from the series. Basically, he's still the same character but stayed with the Predacons based on the events of the Beast Wars episode Maximal No More.

So, he has an arc in this in that he's honorable and will become a good guy again in the end. And of course, feel free to write about this.

- I wanted a female Marvel villain especially as I already had Agatha and Sylvie that I wanted to be consistent. But who I want was a big question, so I racked through who I could pick and Karnilla stood out.

Briefly I thought, I already had Sylvie since, you know, Asgardian, should I have two? But ultimately Karnilla just had more appeal. Her design stood out for starters, especially as drawn by Russell Dauterman as he worked on the Thor comics by Jason Aaron at the time.

Everything about her like her life story and Abilities, it clicked. It felt like "That's it!"

And I just feel it'd be fun if Miraculous Ladybug, Cat Noir and other superheroes of that show went up against a very powerful sorceress who's a Norse Goddess.

- As mentioned, this variant of Karnilla is from Earth-030165. There's still plenty of survivors from that destroyed universe coming about.

- Blowing up the police car, well, I just like doing that and I don't want to get into the politics of how I feel about the police, they're not positive I admit but writing that I think makes for good dramatic irony given the conversation I wrote for Marinette and Tikki.

Especially if myself or someone else decides to follow up on that moment dealing with the aftermath. And it at least makes for a good demonstration of Karnilla being a villain not to underestimate. She's built as the biggest big bad of the three big bad villains for a reason.

That's all I have to say and hope you enjoyed it!

See ya soon!
