Yeet

Daughter of wonderwoman au where marinette finds out her mother is actually Diana and somehow it ends up with her meeting/being introduced to the batfam maybe because she has super strength and is seen yeeting some bad guys who tried to mug her... Or something.

“... you are running from your problems, Mari,” Adrien’s exasperated voice reminded his best friend. Again. She ignored him, and he threw his hands up in exasperation. “Look, you don’t have to do anything about it! Nobody would hold it against you if you decided to just, ignore that you found anything out at all. But you need to actually think about what we just found out and decide whether or not you’re gonna do anything—“ he side-stepped a piece of trash that went flying in his direction. “—or if you’re gonna move on and pretend nothing happened.”

“Isn’t that what I’m doing?” Marinette shot back, pushing her bangs out of her face and tying her hair back with one hand.

“No, you’re currently hiding away in Gotham to avoid your parents while you beat up every random group of idiots who thinks you’re an easy mark,” he retorted. Another wannabe kidnapper went flying in his direction, making him sigh and side step again. She had thrown that one with only her one free hand, showing just how upset she was. “You’re ignoring everything in your life, which is not what we meant we said you should get a little space.”

“I have no idea what you’re talking about,” Marinette dropkicked the last criminal into unconsciousness before stepping back and putting her hands on her hips. She looked over at the now seven passed out men in the alleyway, and the one very frustrated ex-model pinching the bride of his nose. “I think I’m coping just fine.”

“It’s better than being forced to suppress all of your emotions, sure,” Adrien reluctantly agreed. “But not by much. Your angry rampage through Gotham has already attracted more attention,” he raised his hand to point at a nearby rooftop. Several shadows lurked there, looming over the building’s edge. “Which, might I add, is exactly why I told you not to come to Gotham.”

“You’re the one who followed me here,” she shot back before turning to the shadowy figures above them. “Go ahead and come down! But it was self defense, and you can’t arrest or beat me up for defending myself!”

The first figure to drop down straightened your just as quickly, revealing the imposing figure of none other than Batman himself. The little white eyes on his cowl seemed to narrow on their own as he looked down at her.

“That might be true, but I’m sure you know my policy on metas in my city,” he grumbled back at her. He wasn’t necessarily threatening, but he definitely wasn’t welcoming either. With all of his limbs hidden behind the cocoon that was his cape, Marinette would never be able to predict his next move if he did decide to fight. Not that she seemed particularly worried about that as she crossed her arms over her chest and met his glare evenly.

“Oh, do you own this city now? I wasn’t given the memo,” she retorted. “And considering I didn’t even know I was a meta until last week? I think I deserve a little slack. I’m angry and if people think the tiny little girl in pink is an easy kidnapping target, then it’s their fault for making themselves into the perfect practice dummies for me to try out my newly discovered strength on.”

Adrien saw the eyes on Batman’s mask narrow even further. Marinette wasn’t exactly at her most charismatic at the moment, and Adrien didn’t wanna get the both of them into a bad relationship with the experienced superhero who always seemed to know things he shouldn’t know. So he stepped up quickly, getting in between Marinette and the Bat and holding his hands up in a placating gesture.

“Okay, Monsieur Batman,” Adrien started slowly, making sure his posture was impeccable and his smile bright. “She’s telling the truth, even if she’s not... the most tactful about it right now. She just found out some very concerning things about her origin and Gotham is the best place for her to hide from her problems and let loose a little pent up aggression. But— well,” he grimaced. “We didn’t intend to run into you guys, but maybe it’s a good thing we did.”

“How so?” Batman was clearly still incredibly suspicious of the both of them and wasn’t giving an inch. So Marinette rolled her eyes (she was still very moody) and leaned around Adrien so she could get a good look at the monochromatic hero.

“I thank my lucky spots that we ran into you, Batman!” She said monotonously. “Me and Adrien are paw-sitively excited at this opportunity.”

Batman. Froze.

Not only were those two lines the very first lines ever spoken to him by two foreign heroes a few years ago (with a few key words changed to protect identities), but they had become their code phrase for whenever they made calls to one another outside of their costumes. All at once it seemed to hit him— the golden hair and bright green eyes on the boy, the blue-black hair and normally super-focused bluebell eyes on the girl that were currently sporting very uncharacteristic frustration. Their heights. Their builds. All of this info flowed through his mind and compared to the information stored in his memory, and it only took the span of two seconds for everything to click.

Suddenly Batman was at full attention, back straight instead of looming over them and eyebrows clearly raised high under his cowl.

He knew Chat Noir and Ladybug would never take a random vacation to Gotham. Ladybug herself had nearly waxed poetic about how much the city depressed her just from the pictures she saw online. If she had willingly come to visit, it was more than to just blow off some steam.

“Batcave?” He asked, earning a relieved look from Adrien and a moody silence from Marinette.

“Please,” Adrien agreed. “You can probably help us, actually.”

—*—*—*—*—*

Marinette leaned back in the metal debriefing chair, legs up on the table and looking for all the world as the picture of pure teenage rebellion and angst. Coincidentally, Red Hood was in the exact same position in the chair next to her.

Batman and all of his other bats and birds were in the cave with the two off-duty Parisian heroes. Everyone except Adrien and Marinette still had their masks on, since the two Parisians were still not privy to their identities. Yet.

To be fair, the bats hadn’t known the identities of the two miraculous users either before today.

“Cha Noir,” Batman started, only to get a head shake from the blond boy.

“Just call me Adrien. Chat’s out of the bag—“ he ignored the groans at the pun and soldiered on, “—so might as well use my real name.”

Batman nodded. “Adrien, then,” he amended. “Why are you and Ladybug really in Gotham?”

Adrien sighed. “I wasn’t lying, before. Marinette,” he gestured to his hero partner. “Just found out some distressing family news. Since HawkMoth is gone, she doesn’t need to repress her negative emotions anymore. But she also didn’t want to be around her parents while she processed everything. I told her to choose any other city— really, I begged— but she insisted on coming to Gotham.”

“The never ending cloud cover and constant rain seem thematic,” she finally spoke up, reaching into her big over-the-shoulder bag and pulling out a large envelope. She threw it to Batman, making the thin package slice through the air like a knife. To nobody’s surprise the seasoned hero easily caught the projectile between two fingers. He looked at the envelope and back to Marinette, silent questions floating in the air between them. Marinette decided to answer at her own pace.

“That’s what we found out. You see, one of my friends is a huge science nerd. A genius. And he wanted to compare DNA samples between us to see if there were any genetic components that determined a person’s suitability towards certain Miraculous or other magical artifacts over others. It was supposed to just be a fun side project that he didn’t expect any breakthroughs on. He mostly just wanted to satisfy his own curiosity. But instead of finding out if our DNA was linked to the miraculous, he found out that my parents are not biologically my parents.”

“Hence the whole just finding out that you’re a meta thing, right?” Nightwing spoke up, fully invested in the story. “Did they never say you were adopted before?”

“It’s not in the system,” she replied easily. “My parents have all the documentation to prove that I’m their biological child, except I’m not. When I confronted them about it, they caved and admitted that they had adopted me in secret and covered it up. Apparently a friend of theirs was involved in something illegal, and,” she waved at the envelope that Batman was now opening. “The details of what we were able to dig up are in there. The summary is this; their friend was part of a secret, illegal experimentation to create clones that could defeat the Justice League—“ the air seemed to get sucked out of the room as soon as those words left Marinette’s mouth. Everyone seemed to know exactly what she was talking about. “—a group called CADMUS. They made me, as apparently one of their early attempts. But I didn’t exhibit any of the powers they were looking for, or any meta traits at all, and my body refused to mature at the rate they wanted. They had no use for a seemingly normal human baby that they managed to clone, so they were preparing to kill me and start over. That’s when my parent’s friend stole me, not wanting to kill an infant, and begged my parents to take me in and pretend I was theirs. Low and behold, it turns out that my DNA just needed a very specific series of emotions to unlock it’s latent abilities.”

“Those emotions being..?” Red hood trailed off, earning a wolfish smile from Marinette.

“Intense anger, betrayal, and confused frustration closely followed by the desire to punch other people’s faces in.”

“That last one is just an assumption,” Adrien chimed in. “And maybe not accurate. But the first three, our scientist friend was able to confirm. The rapid experience of a lot of negative but action-oriented emotions released whatever had been holding back the powers in her DNA from expressing themselves,” he had switched to French so that he could explain everything exactly as Max had told it to them, but he knew all of them were fluent anyway so it was fine. They nodded along, processing the information.

The crinkling of paper drew everyone’s attention back to Batman, who had been flipping through the detailed break down of everything they had found about Marinette’s situation and how she was made by CADMUS.

“Uh,” Red Robin nervously spoke up. “What’s up, Batman?”

“Your genetic donors...” Batman breathed, getting a wink and finger guns from Marinette.

“Yup. Isn’t that just the most fucked up thing you’ve ever seen? They were clearly trying to make someone who could destroy the world.”

“That makes me nervous,” Nightwing admitted, getting up and going to get a look at the papers himself. “It can’t be that ba—“

When even Nightwing was left agape, everyone else who wasn’t in on it found themselves squirming.

“Just tell the rest of us, already!” Robin demanded after the silence stretched just a bit too long.

“The unknowing genetic donors that CADMUS used to make me,” Marinette spoke up, still with her legs up on the table. “Are a very mad-scientist’s-wet-dream combination of Lex Luthor, Bruce Wayne, and Wonder Woman.”

“We don’t even know why they added Bruce Wayne’s DNA,” Adrien admitted. “Although our scientist friend thinks it’s because of physique. His hypothesis is that, in order to support the genes of Wonder Woman, they had to add male genetics that could support the production of a very high muscle mass and would lean towards easy development of a very athletic body. Lex might be evil-scientist smart, but he’s a string bean. But if he added the DNA of another multi millionaire who just so happens to maintain a ridiculously fit body without putting any obvious work into it,” Adrien shrugged. “Then maybe the clone would be able to support Wonder Woman’s genetics and that of two human donors without falling apart.”

“So I’m ‘the clone’ now, huh?” Marinette snarked, earning an exasperated eye roll from her friend.

Batman just stared at the both of them for a moment. He walked away without a word, and came back with a fresh needle and a box. He placed it on the debriefing table.

“Can I do a paternity test myself?” He asked, his voice suspiciously less gruff than normal. “I trust the both of you, but I rather be safe than sorry with something like this.”

The both of them just stared at him in confusion. They traded a glance, and finally Marinette shrugged and moved to sit in her chair properly. Her shirt was already short sleeved, so she just held her arm out so Batman could easily get a blood sample.

“Sure, why not. But do you just have Lex Luthor or Bruce Wayne’s DNA sitting around to compare, or—“ she shut up when she watched Batman take off his glove and roll his own sleeve up. Realization slowly sunk in as he asked Nightwing to take a blood sample from him.

“Holy shit,” she breathed, eyes wide. “You’re— and Luthor doesn’t know— holy shit this is even worse than I thought,” Marinette rambled, not even noticing as Red Hood moved forward and took a small blood sample from her.

Adrien put a hand over his face and just laughed for a moment hysterically. “Oh my god,” he looked over at Marinette. “You could take over the world.”

“I have the blood of Batman AND Wonder Woman on MY side,” Marinette joked back, also hysterical.

When the bat’s high tech equipment was able to come back with a positive result only a few minutes later, Marinette and Adrien had to sit on the floor and just let it all sink in. Which Batman did not at all help by immediately unmasking himself and trying to make a proper introduction.

“I wanna go beat up random thugs again,” Marinette whined, pulling at her hair. “I’ll put on a mask, whatever, but just please let me punch people. I need to punch people right now.”
