Siblings

Can I get a fanfiction where Marinette is the blood daughter of Bruce or at least the sister of Damian?

Someone on Tumblr asked me this so here is my take on it:

As far as the Batfam knew Damian grew up with Talia to become the heir for the League of Assassins what they didn't know was that there was something that kept Damian from reaching to Gotham earlier and the only person who knew was Jason. Damian has been keeping this secret from his family since forever. He never was going to tell anyone else about her ever. What he never expected was when he and Jason were dying by the hands of the Joker and the rest of the Batfam tied up was his precious sister Marinette Wayne to come and kill the Joker right there

"NO ONE TOUCHES ANY OF MY SIBLINGS WITHOUT A PRICE!" she yells.

That's the sister I remember I think.

"You cannot leave me right now brothers! You can't do this to me! Stay awake! I can't lose you too!" she shouts.

She takes her knife and cuts her skin

"by the power of creation itself I heal you my brothers Jason Todd and Damian Wayne,"she says before we all go unconscious.

When Damian is finally awake he sees his sister Marinette sitting beside me singing their childhood song she made up.

"Finally you awake! I thought I lost you!" she said before hugging me.

"You know I'm stronger than that," Damian assure her.

"Promise me you'll never leave me," she says.

"Promise," Damian confirms.

"Damian you have a lot of explaining to do, you too Jason," Bruce says.

"There's no easy way to put this but meet my twin sister Marinette Wanye," Damian says.

"She and Damian were raised by Talia to become the next generations of the League of Assassins," Jason explains.

"Is that why Damian didn't come to Gotham earlier?" Dick asks.

"Yes, Marinette and I made a plan and had to execute it for the destruction of the League, we destroyed everything, from its history to all the members except the kids," Damian explains.

"It was all Marinette's idea," Jason adds.

"Stop giving me all the credit without you I wouldn't have been here today," she says.

"So I have another daughter," Bruce says.

"Yes you do father meet my twin sister," Damian says proudly.

"Now we have to teach her the no-kill rule," Bruce says.

"I don't kill only in dire situations," Marinette says.

"Oh no! There's two of them Bruce! Make it stop!" Jason yells.

"Wait how did you heal me and Jason?" Damian asks.

"You'll never know," Marinette remarks.
