Don't mess with Plagg's kitten.
(Also known as Plagg aggressively adopting Adrien as his kitten, and making anyone who hurt the kid suffer.)
Plagg always tried to hide how much he cared about his owners—but he always thought of them as his kittens—focusing on cheese to try softening the blow of inevitably losing them.
But Adrien had managed to worm his way in, no matter what Plagg threw at him to try keeping a distance. Adrien was different from all the others, even though he was going through more shit than all the others, he was pure and innocent. A kid with a missing mom—for less than a year, good freaking lord, this kid was taking it like a champ—and a neglectful father. No matter what life threw at him, from rejections from Ladybug, to his father being a dick, he was always trying to see the bright side.
Until now.
Right after Style Queen, Gabriel left the house and hugged his child who nearly died—like a normal human being would, the fact Plagg saw this as a feat proved there was a problem here. But at least they cared about each other. Was that care of a good quality? No. Absolutely not. Adrien gave everything, and Gabriel gave very little. Adrien seemed absolutely delighted to have even an ounce of Gabriel's positive attention or approval. Gabriel deprived him of the emotional bond they really need as father and son. They especially need that bond more than ever after the loss of Mrs. Agreste. Gabriel, however, decided to keep himself preoccupied too much with business to show Adrien the attention he needed. Adrien, in turn, had gotten to the point he was afraid to even bring up things he wanted, because he expected a negative response.
But something about that hug had made Adrien happier than Plagg had seen in a long time. But right after Chloe revealed herself as Queen Bee, the neglect came back—and broke poor Adrien even more.
It was 10p.m, a week after Queen Wasp. They had just gotten back from patrol, and Adrien crawled into bed, taking shaky breaths.
"You okay, kid?" Plagg asked, wanting to make sure his kitten was alright without letting it show.
"I-I'm fine." Adrien answered, but the crack in his voice betrayed him. Plagg came closer and saw Adrien was fighting back tears.
"Adrien, you need to let this stuff out. I don't want you to think you're alone. As I've said before, you're the best Cat Noir I've ever had. I don't want to lose you until you're too old to stand."
That got a chuckle out of the boy, thank goodness, but his mood darkened again, "F-Father…we're doing another parent project at school, and he snapped at me! Then he said I had to schedule an appointment!" He was sobbing into his knees, "I-I thought things were getting better. They were, up until Chloe…"
Ah. Plagg realized, the cycle had started again. Most abusive relationships got as far as they did because there were reasons to stick around. Adrien liked his father because of one reason or another, so he attempted to look past all the bad for the good. Many victims ended up blinded by this and their hope it'll get better or that it'll go back to how it was before. Adrien loved his father despite the treatment he received, to the point he would take any inkling of love and care he receives and celebrate it enough to keep being looped back in to the relationship. He started to doubt the love but then received some of it and then the cycle started all over again. While Plagg wanted Adrien to be happy, he also wanted Gabriel arrested for child abuse.
He stayed with Adrien until the by fell asleep and made his decision. He was the god of fucking destruction, and the murderer of the dinosaurs—he was getting some revenge. Nobody hurt his kitten without severe punishment. And he would be aggressively adopting Adrien.
He floated out of the room and into Gabriel's atelier, where the designer in question was working on the computer before…
Nooroo appeared from behind him, floating silently and solemnly. No fucking demon way! Plagg internally shrieked. He hated Hawk Moth as well, for targeting Adrien and constantly getting him nearly killed. And now the two people he hated most were one in the same! Forget child neglect, this is full on attempted filicide!
He needed to talk to Nooroo. Gabriel needed to be behind bars—or dead, Plagg honestly didn't care which one. But there were so many things that could go wrong, like the aspect of a legal guardian.
He watched Gabriel for a bit, until the villain walked up to his bedroom, miraculously falling asleep nearly instantly. Pun intended.
"Nooroo!" Plagg whisper-yelled, trying to get his long-lost brother's attention.
"Plagg?!" Nooroo floated over, through the door so they could talk, "What are you doing here?! How did you find me?"
Plagg gripped him in a hug, "I'm so glad to see you!" He smiled, "And now I know where you are. I need your help, I've decided to get Gabriel arrested, but not before making his life hell. Though my kitten is his son," loophole in not saying the name, "I need to know if Gabriel has a legal guardian for Adrien in the event he gets arrested."
"I hate to say it," Nooroo said, "but I tried that. Master won't listen. He doesn't have one for Adrien, insisting he won't get caught."
To say Plagg was mad would be a severe understatement. No, he was enraged. He wanted blood. And now his revenge had hit a block. Damnit! Well, time for some more plotting.
"Nooroo, I'll work on my revenge. Where's his lair?"
"Under the painting of Emilie Agreste. Elevator."
Plagg smirked, "Thank you. I'll be back!" He floated back to the atelier and crossed his tiny arms. What to do… First, he decided to attack the computer, by phasing through it and using a very nerfed Cataclysm to destroy everything in it, including the memory file. Even if he had a hard-drive, it wouldn't help. It was dead inside and could easily be blamed on a virus or angry computer termites—is that a thing? No. But Gabriel wouldn't be able to prove it.
As much as he wanted to do more, he decided that was enough for the night and flew back to Adrien's room. He fell asleep in his kitten's hair.
OoOoO
"Um, hi," Plagg said, using a school phone in secret, "I am…uh…Thomas Astruc. From social services. Is this Gabriel Agreste?"
"No, this is his assistant, Natalie Sancoer."
"Okay then." Plagg said in a deep voice, "I was supposed to send this call a year ago after Mrs. Agreste went missing, but who is Adrien Agreste's backup legal guardian? In the event something tragic happens."
There was no way Natalie would buy this. "Adrien doesn't have a godparent."
"Well get him one!" Plagg snapped, "Otherwise Mr. Agreste will be arrested for child abuse!" He hung up and quickly made his way back into Adrien's bag. First, he would make sure his kitten was okay, but tonight would be more trouble causing.
Adrien sighed in relief upon seeing him, "Plagg, I told you I would give you the cheese later. You scared me."
Oh god, that hurt his heart. Adrien was giving him big kitten eyes and Plagg floated back into the bag, now that people were coming in the locker-room.
Adrien walked out the door, Chloe latching onto his arm. They began talking about the project they were doing today after school—Chloe was just gushing and being quite sexually harassing. This made Plagg even more angry, remembering this bitch was the one to ruin the hour of bliss, and was part of the reason Adrien had cried last night. Gabriel could wait, he had an opportunity.
OoOoO
They were in Chloe's room, with Adrien working on the project in frustration while Chloe did her nails. Plagg didn't feel the slightest but guilty about what he was doing—in fact, he was slightly excited, this bee-themed bitch would be a guinea pig for the trouble he had in store for Gabriel.
He made a mental note to do something nice for Nino, because that boy was great and always kind to Adrien.
He made his way to the dumpster outside, via going down from the balcony, and looked around, finding two perfect, dead rats. He brought them up and quietly made his way to Chloe's closet and placed them in her shoes, knowing it was unlikely she would check before putting them on. Even if she did, she would still suffer and not sleep for at least a weak.
He chuckled, realizing he was a bit of a sadist. But he didn't care. Adrien was the most important thing to him—second being camembert, not that he would tell Adrien it wasn't the other way around.
Next step to the 'make Chloe miserable' plan.
He wondered what the inevitable security cameras would think of this, since kwamis couldn't be filmed. Just some floating rats, hanging out.
He found his way into the bathroom, looking for something to ruin. A bad smell could be solved quickly, too quickly to be acceptable. He needed something better.
Then he saw her nail paint and her curling iron.
Somewhat giddy now, he floated into the curling iron, ruining it from the inside like he had with Gabriel's computer. But he kept it just intact enough to completely fry Chloe's damn golden locks within second of contact. He then moved to the nail paint and poured random colors and toilet water into each, leaving a mess that he quickly cleaned up.
He flew back into Adrien's bag and decided to plan his next scheme for Gabriel. Lair via elevator, Nooroo had said…
OoOoO
Adrien was getting ready for bed, frustrated after working on the project alone with only nagging from Chloe, making Plagg even happier to have made her suffer.
He floated to his kitten and began licking him.
"Plagg…what are you doing?"
"Shut up kid and stay still. Let me groom you."
Adrien shut his mouth and let this happen, until… "Are you purring?"
"No!" Plagg defended, "I'm not purring! You're purring!" He sighed, "Fine. Maybe we're both purring." It was him and only him, and he knew it; but Adrien did end up purring by the end of it, falling asleep. Plagg pulled up the comforter and made sire his kitten was sound asleep, before going off to use his evil plan. He didn't forget to strap a go-pro to his head.
He and Nooroo met up right outside Gabriel's room, and Nooroo led him back to the atelier, and down to the lair, Plagg waking a video of the entire thing—he admittedly was quite disturbed by finding Mrs. Agreste in a coffin down there.
Plagg turned off the video and did one more thing before he left: he broke the part of the window where the akumas could leave, so they were stuck in there. Then he destroyed the panel where Gabriel would go in, so a) he would plummet and need to be rescued, and b) would be attacked by the butterflies.
He again wondered what the security cameras were making of this.
They flew back up and Nooroo finally spoke, releasing a long-held breath, "I assume you were Mr. Astruc."
"Yup." He answered proudly, "How'd I do?"
"Alarmingly well." Nooroo said with a smile, "Master and Natalie nearly had panic attacks. Natalie's been named backup guardian."
"Oh," Plagg said before leaving, noticing there was sparking from the computer, "And might I ask how dear Gabriel reacted when finding his ruined computer?"
"He was enraged. He had a copy of all the files of the Miraculous book, with his notes on there. He cried for a good twenty minutes and screamed when the repair man said there was nothing he could do. Nobody guessed you'd had anything to do with it."
That was a relief. And hearing Gabriel had suffered made his heart happy. Sadist indeed. Plagg hugged Nooroo again and flew back to Adrien's room, downloading the video onto one of the computers, then onto a backup hard-drive in the event a real mystery virus came along. He would use it soon, very soon, he would send it to Alya. But he needed to make sure Gabriel was even more miserable.
OoOoO
Chloe came to class the next morning, in a hoodie, covering her hair—and gloves to hide her hands. Everyone stared questioningly, but didn't say anything, until Miss Bustier was about to start class.
"Chloe, no hoods in class."
"My daddy is the mayor! I can do what I want!"
"Chloe…" Miss Bustier's voice held a hint of warning, showing just how put up with this shit she was.
Chloe slowly—painfully slowly—removed her hood. The curling iron trick had worked better than he'd ever imagined. Her hair had completely fried off, leaving her with a haircut even a mildly unattractive hedgehog would find unappealing, despite the resemblance.
Everyone tried to hide their laughter. But Plagg couldn't. He zipped to an air vent and laughed hysterically.
"MWAHAHAHAHA!"
What he did not expect from this though, was for Rose to scream about an akuma, and Miss Bustier to usher the entire class to go home.
Plagg went back to Adrien's bag, "There is no akuma. Sorry, that was me."
Adrien just rolled his eyes, "Did you have something to do with Chloe's misfortune? She was also squealing about having steps in dead rats that were placed in her shoes this morning."
"How could I have done that, Adrien?" Plagg asked with as much innocence as he could muster, "I was in your bag, trying to ignore her the entire time I would have gotten the opportunity."
"I suppose that's fair." Adrien muttered, walking home and to his room, because Natalie was getting groceries. He went to take a shower—for real this time, not as a lame excuse—and Plagg went back down to see how his tricks were working, when he suddenly heard an "Ah!" From the atelier.
He made his way down there and saw Nooroo, only Nooroo.
"What happened? Did my plan work?"
"Yes!" Nooroo said, laughing, "It was amazing! He pressed the buttons, the trapdoor opened, and he plummeted. Though fortunately he's not dead, because that would be hard to explain to Adrien. I can hear him screaming, you?"
Plagg listened, and heard Gabriel screaming curse words and trying to shoo away the butterflies.
"Maybe you should take a break." Nooroo said, "You might make it suspicious. And while I agree what he's doing is wrong, he's trying to get his wife back."
"Fine." Plagg grumbled.
OoOoO
Don't let that agreement fool you, the minute Gabriel was neglectful to Adrien again, Plagg gave the video to Alya—it hadn't even been two weeks. And you can guess where that went.
Adrien was mad at first, but when 'Doctor Fu' woke up his mother from her coma—and it was painfully easy. The whole situation could have been solved with a 'hey, fix her' and without 99% of the drama—he calmed down just fine.
Gabriel still got his ass busted though.
And Plagg was fine with that, because now he had Emilie alongside him to make anyone who hurt Adrien suffer.
Nobody messes with Plagg's kitten. Lest they suffer the consequences.
