summary: meet jinx, gotham’s loudest, most explosive villain. no one knows who they really are, or if jinx is really even their name. but one thing’s for sure — they’ve got a lot of people chasing after them and their reasons aren’t so noble.
status: unedited

Considering Jinx was inspired by Harley Quinn. You’re probably her protégé. Her darling little child with Joker.
YOUR ORIGINS:
She saw you in the aftermath of the explosion. Cold and alone. Fire roaring behind you despite the heavens pouring its heart out, as if it was desperately trying to wash your tears and pain away.
She saw your bruises and a girl a little older than you walk away.
Her heart ached for you. No child deserved to be put in that kind of position, so she stepped in and made herself known.
“ I . . . I only wanted to help . . . Don’t leave me . . . Don’t . . .
You muttered.
Joker, who came here to marvel at the chaos such an explosion would present smiles maniacally.
You. You were the one that did this.
This beautiful wreckage and an equally beautiful child.
You were practically begging to be moulded into a weapon.
You charged at them both as they got closer, and while Harley was ready to defend her man - even hurt you if she has to - they did not expect what came next.
You just, held unto Joker’s right leg.
“ She’s not my sister . . . No . . . if she was she wouldn’t leave me . . . “
You were far too emotional for his liking. But nonetheless. A boon can always be found in a curse. That is, your desire for revenge.
He takes one look at Harley before picking your small body into his arms.
“ Who cares about fools like them, little one? They don’t matter in the grand scheme of things.”
His smile never stopped widening, yet even as a kid you never saw it as creepy or unnerving. In fact, it only reminded you of the smiles you used to draw on your nail bombs.
“All we ever truly have is ourselves. “
“So, smile. Don’t let your tears bring you down.”
Moulding you into the perfect weapon was easy.
Having a psychiatrist as a partner did help a lot in your development.
All it took was a few reminders of that fateful day before you began obediently following their rules and instructions.
You were a genius and since Harley kept protesting against it. You weren’t baptized into a vat of acid like the couple was.
Now, Harley and Joker are the worst possible parents you can ask for. So unlike Arcane’s Jinx. You are way way more unhinged. Not to mention, horny and materialistic.
As you grew up, you began to take interest in intentionally hurting people just for the sake of it. Stealing things was just a normal Tuesday for you. Being successful in your endeavors for once, and having bigger stacks of cash felt exhilarating.
The women and men were amazing. Your pseudo parents being who they were, didn’t really care if you were a sexual deviant or a pervert. When your hormones started kicking in they let you do whatever you want. Even giving you some of the people he held hostage as a toy to play with. If you have the capability of getting someone pregnant/or getting pregnant yourself they wouldn’t really care about the baby but you knew them well enough to know they’d use the kid as a way to manipulate you so you were careful in that aspect anyhow.
Harley noticed that when laying with women you’d often call out your sister’s name or call them sis by itself.
Sick. Disgusting. Is what a normal mother would think after finding out such a fact.
But to her you were just growing up so quickly. She had convinced Joker to go ahead and kill your sibling a long time ago behind your back and was growing anxious with the thought of you hating her and ruining this happy family dynamic (she had in her head)!
So she starts bringing you to more heists in disguise. Always keeping a close eye on you so that if any of those stupid heroes and vigilantes get any close, and you too far. She’d know as soon as possible.
It’s safe to say you grew up pretty spoiled, but even then you were hungry for more.
You see, even if they (Harley and Joker) weren’t careful with their “parenting” approach. They were careful with keeping you hidden from the Dark Knight himself.
Not that they were scared you’d get hurt. They could always nurse you back up again. Harley actually enjoyed the times you’d gotten in the cross fire. More time to take care of you in her arms.
They were mostly scared of the Dark Knight stealing you. Afraid that he’ll take you away and turn you into a goody-two-shoes they wouldn’t recognize anymore.
So as much as you were more involved it still felt like they were babying you.
It was your situation with you family all over again
But this time, this time you’ll show them…
You weren’t weak. And it’ll do them good to remember that.
YOUR RIVALRIES:
You made your debut at around the time Tim was still Robin.
You were his very own Joker. A menace deal with. A person that only cared for the thrill that came with hurting and killing masses.
You were terrible. Evil. A demon he had to exorcise from this world.
A demon he fell hopelessly in love with.
He didn’t know how his feelings came to be. It may have been the amount of stress and pressure he was facing coupled with having to deal with your ass every damn day whether directly or indirectly. But he found himself yearning to see you at times. Getting warm when he thought of you. He felt solace knowing that no matter how many times he’d attempt to tear you down completely, you’d still come back to face him once again.
He was so guilty of his feelings. How could he fall for someone as heinous as you? You were the worst of the worst. But somehow that made things so much more better.
You were a taboo. A vice he couldn’t have. The thought of entering such a forbidden relationship excited him just cause it was just that — forbidden , a temptation that should always stay like that.
He somehow manages to gain the self control to stay away from you for a while.
But then came Damian and he was set to replaced. Just like that.
“Wow there Timmy Boy. You look like shit.”
“J-Jinx?! Why are you here? How do you know my name?!” He asked as if he didn’t know every single detail about you himself.
“I have to know my little birdie well don’t I?”
“What kind of archnemesis would Jinx be to their little Robin if they didn’t do a lil’ research?” You spoke in a higher, cutesy voice as if you were your handgun that you’ve affectionally named Zapper.
“Right you are Zapper! I would be a terrible rival. That wouldn’t do for a hero as great as Timmy!”
He thought that all his work was all for naught. All the hours he spent trying to prove himself was gone so fast.
But you reminded him of his place in this world. Of his position as a hero. Your rival.
The warmth in your eyes when you looked at him sealed the deal. There was no coming from this. He was yours as you were his.
“Only I can hurt you like this, toots. Don’t forget that.”
Little did you know that Tim took those words to heart and never let anyone else hurt him (and stay alive).
“Big Bat can replace you but you’ll always be the Robin in my heart !” You winked at him, signaling with one of your manicured fingers for him to smile. Which ended up almost scratching your cheeks.
Tim was confused (incredibly flustered, not to mention har—), why were you so kind to him all of a sudden. He knew you were the playful type but you were usually ruthless when it came to battle. You weren’t one to play with food for too long. For you to excuse him, much less help him in such a state.
Who were you and what did you do to his Jinx?
“OW hEy! I swear if you put that there Pow-Pow— I’ll—“ Tim heard you screeching out of view.
Scratch his doubts. Yep, you were definitely still his Jinx.
The Dark Knight knew who you were from the beginning.
He had his suspicions even before you came into the scene. With your knack to tag everything with neon spray-paints.
At first he thought you were a simple thug that Joker and Harley picked up. But the way they were sheltering you made it seem otherwise.
The regret he felt knowing that you were basically a child in their filthy hands and was now far too gone to save was immense.
If only he knew. You wouldn’t be in this situation.
While he was “dead” he found himself looking into you more. About the death of your biological parents and the way your sister abandoned you to Harley and Joker.
He felt pity for your childhood and a sense of kinship. Sure the incident may have been your fault but you were a child. How could you have known your actions would have such terrifying consequences.
If only you knew him when you were younger.
If only.
He was sure you’d be one of the greatest vigilantes alive.
“I knew you were alive.”
You looked down at Batman, staring while both of you were being doused by the rain. Thunder accompanying the sound of conversation.
He takes a defensive stance.
“I’m not going to fight ya, that’s Joker’s thing. And I know he’ll grill my ass if I stole his archnemesis.”
“What a loser!”
“Hey! He took us in. We should be more grateful!”
Bruce looked at you as you talked with a new, rather large, shark shaped gun. He had memorized the names of all your “companions” by now and was oddly excited and slightly unnerved by the new one.
“So, why’d you leave? Was it . . . was it on purpose?”
“No.”
“Then come back.”
He almost dropped all his plans with the way you told him that.
“Tim needs you . . . and your other sons too or whatever.”
“Come with me.”
“You crazy, old bat? Why would I—“
“I know what it feels like to have no family. Harley doesn’t love you. Joker doesn’t love anyone.”
“Do you?”
“I do.”
“Well tough luck man. I don’t give a shit about love.”
You dropped down to his level. A thud resounds, loud enough to cut through the rainfall and thunder.
“Cause love never gave a shit about me.”
“We’ll have to refuse. Just get back to your sons, hero!”
“I’m sorry, perhaps I didn’t make it clear enough—
— I don’t think you have a choice in this matter, [Y/N].”
