You're a kid of Joker and Harley Quinn. Yes, The Joker, and this Harley Quinn, the unfamous clown criminals of Gotham. Ever since you were a kid you participated in their not-so-legal activities. And your father, even with what kind of psychopath he is, was very happy and amused at how his child turned out to be just like him. But then everything changed when the fire nation attacked. Joking, it actually changed after your parents broke up. Of course Harley took you with her, not wanting to leave you alone to be brainwashed by your father. So now, you live with her, her girlfriend who is Pamela Isley aka your auntie Pams, and you're going to Gotham's school for troubled teens. Oh, and of course your mom basicly froced you to abandom your supervilian persona. Just perfect life, isn't it?
Well, it could be (even tho it's far from it), but now, your father's back in Gotham, and... well, everyone's looking at you like at ticking bomb. Waiting for the moment you rejoin your father to help him swell the city in chaos. You wanted, you had to take some action, to make a new name for yourself. But Bats don't trust you in slightest, and your mom would lock you up in your room, most probably. So it had to be a solo thing.
">Tt<." You heard a voice of tongue clicking, and when you turned around you could see the newest Robin. "And what are you doing here, Quinzel? On your way to join your father?" He asked, his eyes narrowed and his hand on his sword. Not like you were suprised, last time you went out like that it was to... well, be the one causing the chaos which is happening around you now.
