Harley makes Batman her twin.

Harley immediately swiped the sensitivity slider back down to around 50%, her finger ready to move it back up to 130% if she didn't give her an answer she liked.

"Anything, huh? I like the sound of that!"

The blonde perused the genetic code templates on file, finding one of herself and one of Punchline.

"I think you're going to help me get back at the Joker. Then we'll go and rescue those dumb broads the assassin pricks kidnapped. Whaddya say?"

Bruce fell on her knees, gasping from the feminine pleasure she just felt, unlike anything she had experienced. She wondered if this could be ****.

“Like, get back at the Joker? Then get the other girls?”

She repeated this. She didn’t like the sound of it, but she understood that she was entirely in her hands. If she said no, who knows what she’d do… and at least they could still save those girls.

“Like, I mean, sure… Can you make my boobies fit in the suit again?”

She couldn’t believe she just called them her boobies. She wished a pit would swallow her up.

"Sure, why not?"

Harley complied with "Cassandra's" request. She turned the dial down, returning her proportions to what they were before she started tinkering with them. Though, this Cass chick was already pretty busty to begin with.

Harley flipped through the genetic templates and a mischievous grin crossed her lips. She tapped the image of her mugshot, confirming her selection in a pop-up menu.

CONVERTING . . .

Bruce's suit shuddered, her body shifting as she grew only an inch to match Harley's height. Her breasts inflated one cup larger as her skin became lighter and her hair turned bleach blonde with pink and blue highlights. Her face rearranged as the suit's vocal chords adjusted, the feeling of the suit moving around like that causing Bruce to feel the same sensations she experienced when she initially put it on.

In seconds, she was the spitting image of Harley Quinn, the only difference being her hair wasn't up in pigtails and she was still wearing that dumb "Black Bat" suit.

Harley clapped giddily.

"You're gorgeous! I love the new style, hon'. But you gotta ditch that stupid batsuit."

Bruce felt her body shift and distort underneath the tight batsuit, and once she saw the blue and pink highlights fall on her face, she knew what Harley had done.

"Are you, like, kidding me? Why am I YOU now?"

The valley girl modification still in effect, now with the high pitched tones of Harley Quinn, made the Dark Knight sound like a bubbly new york babe.

"And… you want me to ditch the batsuit...?"

She looked down, and noticed how much tighter the suit was with Harley's slightly bustier, taller body. It looked completely bizzare for Harley Quinn to be wearing black like this... ugh but you're NOT Harley Quinn! You're Bruce!

Sighing with resignation, knowing that Harley could **** her to change anyway, Bruce started to unzip the batsuit from the back, her pale face blushing.

"Like, Can I get some privacy?!?”

After hearing Bruce's valley girl tone mixed with hers, she snickered. Fiddling with the tablet once more, she adjusted Bruce's voice to match her own.

"Privacy? Pffffft! Quit bein' so modest! It's not like it I ain't seen it before!"

Harley coiled a brow, placing a hand on her hip and grinning widely at the Harleyized Dark Knight.

Bruce saw her press a couple of buttons on the tablet, which got her worried.

"Hey, whatcha' doin' to me now? Are ya..."

She realized her speech pattern had changed once again, to fit the Brooklyn accent that Harley had become known for.

"Goddamn it."

Bruce swore.

"Take it all off, sistah."

The blonde opened her closet, picking through a few articles and putting an outfit together.

She removed the rest of her batsuit, and got down to the lacy black bra and panties that she had so much trouble with before, as Harley started getting her new wardrobe ready. She sighed, examining her new body... or as much as she could see below her breasts...

"Sheesh, I didn't take ya for a lace girl, Bats. Thought you woulda wore boyshorts or somethin' underneath. You really went all out for this whole girl thing, didn't ya?"

Harley laid out a black and red tank top, matching shorts, gloves, and leggings.

"Put these on and we'll head out."

She waved to the clothes.

"Keep the undies, I like 'em. They suit ya! Hahaha!"

"They ain't mine! This was just for the mission!"

Bruce tried to defend herself against Harley's taunts but felt silly. She had decided to go along with this plan. Bruce didn't realize how much his masculine pride would be bruised by one clown girl making fun of her. But this was the bed she made for herself.

She started putting on the uniform, and unfortunately, didn't feel any more covered. She was still wearing a skimpy outfit, and now in the bright colors of her arch-enemies ex. What little bit that was covered, like her legs with the leggings, felt to only exemplify what was underneath...

Bruce finished putting them on, looking very similar to Harley, except for the pigtails. She sighed.

"There. Ya happy now?"

She might be **** to do this, but she wasn't going to give Harley a satisfaction in seeing her squirm... more than she has already at least.

Harley went to work tinkering with some rather intricate settings while her twin dressed herself. She enabled the protocol that only allowed Bruce to refer to herself as "Harley Quinn" so she couldn't refer to herself as Batman or any other name out loud. She switched up the mannerisms to match her own to a T, even the suit's fighting style. Instead of skulking through the shadows and gliding around with a utility belt of fancy expensive toys, she'd have to take a more direct approach to combat. She'd still have to fight hand to hand but she'd rely more on her environment and her blunt weapon to take down goons. Cartwheeling and acrobatics were going to become vital if the freshly christened jester didn't want to get curb stomped.

Harley set the tablet down, locking it behind administrative permissions. She tied her twin's hair up into pigtails after sorting the pink highlights from the blue ones.

"There ya go! Geez, I look hot."

The psychotic psychologist debated staying home and just screwing around with the tablet and her prisoner's suit but ultimately decided against it. What she had in mind was far more sinister and was going to be infinitely more entertaining.

"Here. Take this, you're gonna need it, dollface."

She tossed a baseball bat to her doppleganger.

Bruce caught the bat in midair, feeling the weight of it... it shouldn't feel this heavy, and she could definitely swing it, but it made her miss her old body even more. However, it felt... natural in her hands. She swung it around a couple of times, mimicking Harley Quinn's unique and chaotic approach to combat. And despite her feeling incredibly out of place in this body, after Harley pressed those buttons, she felt a bit lighter on her feet. She moved her legs a bit, even doing a couple of high kicks, realizing she shared Harley's flexibility.

"Jeez, whaddya do? Make me fight like ya or somethin'?"

Her detective instincts were still top notch after all this, even with her hair up in pigtails.

"So what, you're gonna make me beat up Mistah Jay with this bat?"
