Batman adopted joker's kid!(DC &OC)

Hi mum! Hi dad! Don't kill me!

They had tried to stop the whole prison plan even with the justice league and the young justice they lost! And now they were in a massive room with a laser door,  all tied up with superman and superboy were sat by a crates of kryptonite "you little evil brat!" Superboy spat at Quinn
"How is this my fault!?" She cried "oh yeah because of my parents!"
Then there was a cackle that Quinn new all to well
"No!" She whispered and she started to struggle
"Oh quinny my lovely, wretched of a daughter!" Came Harley Quinn's voice and Quinn struggled tears ran down her face she tried to set herself on fire but she had some sort of collar that gave her an electric shock each time she tried. The laser door shut off long enough for the two villains to enter and they knelt down by Quinn
"H-How d-do you know it's me?" She stuttered
"Oh please! We will always know those eyes!" Joker squealed they then grabbed Quinn by the collar and threw into the wall and they drew their weapons and attacked taking out their anger on her, the bats all struggled and so did the league but they couldn't break free.
They shoved Quinn against the wall but she had a determined look in her eye she now had a broken nose a few ribs and her other lung had probably been punctured "ok no! I HAVE DONE NOTHING TO YOU! ALL I DID WAS BE BORN AND SUDDENLY I'M THE BAD GUY! YOU HAVE HURT ME TOO MUCH AND SENT ME TO WAR! BECAUSE OF YOU I HAVE PTSD, ANXIETY, AND A LITTLE DEPRESSION AND I AM SICK OF IT YOU WILL LET GO OF MY FRIENDS AND THE YOUNG JUSTICE BECAUSE I HAVE POWERS AND I AM NOT AFRAID TO USE  THEM NO MATTER HOW MUCH ELECTRICITY YOU SHOCK ME WITH!!!" She screamed wincing as she did so, her parents look taken aback and then they all noticed the orange in her eyes like the dying embers of a fire, Quinn set her self on fire her suit not burning but as she got angrier the flames turned blue and so did the fire tattoos on her neck and wrists and (unnoticed by them) the tattoo on her back, the flames burnt through the collar and Quinn wrapped the heroes in a protective dome as she unleashed her power and the flames made the shape of a Phoenix behind her. The building started to crumble and the floor cracked the villains looked petrified a face they didn't think they had!

Bruce opened his eyes to see the barrier down and the entire building collapsed but what he couldn't see was Quinn, he ran to where she was once standing and started to dig he dug up the alive bodies of Harley Quinn and the joker which Aquaman and cyborg quickly apprehended, after a few minutes he found her, her breathing was ragged but all in all she was ok, she looked to him and smiled "hi dad" she whispered before blacking out.

She had had to stay with the justice league for two weeks but that was fine as she just grew closer to them but she was excited to go to the mansion.

She stood their and looked up at the house
