AN: welp here we go, after 3 years of not writing, here I am giving it my best once more. I am in love with these characters please do understand that I own nothing. The reader's superhero name is chickadee, just so you know.

You were never a fan of large groups. Back in the circus with your brother, you rarely spent time with the other children. Your mother and father often tried to get you to open up to others. But that was never really your style.
Especially after they died.
When you were taken in by Bruce Wayne, unlike Dick you didn't try to run away. Much to the billionaire and his butler's concern, you barely moved, barely ate, barely talked. They tried giving you room, but nothing changed. It wasn't until they manage to get through to Dick that they managed to get through to you.
You and your brother had always been close, but after the death of your parents you were even closer.
You trained together, went on missions together. When he was Robin you were Chickadee. You did everything together, people often assumed you were twins, but you were actually two years older than him.
"Y/N?" You quickly realized you'd been lost in thought when your mentor called out to you.
"I'm sorry, I was just thinking." You quickly explain.
You were hiding in the beams of a warehouse by the docks of Gotham. You'd been tracking a gang led by Harley Quinn for months and had called your mentor for the final show down.
Now, one might wonder why Harley Quinn would lead a gang by herself when she usually seemed to do everything with the Joker. At least, you wondered. As soon as you'd heard of it, you knew you'd have to investigate. You quickly found out that Harley Quinn was dealing drugs behind the Joker's back. It wasn't any drug you'd heard of before, it's effects were described as hallucinations, and psychic abilities. Of course, no human body could handle the strain of that easily. Most people died within 48 hours. But 48 hours was usually enough to do serious damage. The drugs hadn't quite hit the streets yet so this was your opportunity to stop Harley Quinn.
"Chickadee, what would you like to do?" Asked you mentor
"I'll take the left, you go right. Disarm the cauldrons, erase the formula and burn whatever's left. I'll take Harley."
Bruce gave a satisfied nod from under is mask. Turning away and heading right.
"Also" You called after him, "don't forget..."
"Toxic fumes?"
"Yeah."
You ran to your objective, knocking guard after guard down. You could see Harley bent over a large cauldron of bubble gum pink drug. Unfortunately, one of her goons noticed you, there goes the element of surprise, you thought. Unfazed you ran towards Quinn, dogging knives, knocking out stuff... Soon it was just you and her.
"Oh no! The little Chickadee got me!" She giggled.
"You'll regret that." You smirked.
She swung her hammer and you dodged, falling onto a table that you hadn't noticed before. You heard a metal clanking noise.
"Whoops! Looks like the little birdie is in a cage!"
"You'll..." before you could finish your sentence you received a hammer in the face.

You slipped between reality and unconsciousness for an amount of time you simply couldn't pin down. This time, reality stuck. You looked around the dark room you were in. You could just barely make out the shapes of dolls, toys and other things one might find in a carnival. That's when you realized you were in an old warehouse used by the Jokes as headquarters. Well used by Harley Quinn. The only source of light was a bright fire contained by tin toys and fed by pieces of ripped apart toys.
"Good morning sweetie! Had a nice nap?" Said the high pitched voice of the Gotham villain. "Oh Chickadee! I knew you simply couldn't resist a good lead! That's why I started this drug deal" she chuckled, "oh you heroes are so predictable,"
You were angry. Rage boiled for Harley Quinn, every other villain paled in comparison to her evil in you opinion.
"Well, I know you simply can't wait to get out of here!" She said leaning over your body, "Batsy's gone mad looking for you, we wouldn't want to worry the old man..."
She walked a few feet away from you and grabbed a long stick before heading towards the fire.
"I want to kill you, but where's the fun in that! Also puddin' won't let me!" She pouted
You pulled against your restraints, feeling them starting to give out. A little more, you thought, just a little more and I'm free.
Harley Quinn walked towards you a red hot branding iron with her symbol on it. You pulled against your restraints, you were so close. Harley put the iron to your skin and you screamed.
She pulled away, still screaming you made it through the metal binding you. Grabbing the metal rod from her hand you tripped her and made your escape.
You exited the building but didn't recognize where you were. You started to cry, feeling powerless.
"Y/N?" You looked up and saw Robin, or as you knew him, Dick Grayson; your brother.
You smiled, and tried to answer but your lips felt dry and your vocal cords raw.
"C'mon, let's go home." He said, offering his back. You hopped on and he carried you in a piggy back all the way home to Wayne Manor.
