After a mix-up at STAR Labs, Harley Quinn and Batgirl have been fused into a single body with a split mind! Batman has sent you to return them to the Batcave, so they can be unmerged. When you finally find them lurking in the shadows of a Gotham alley, the fusion—Batquinn—stands before you in a dramatic pose, arms outstretched like bat wings with her purple and red cape flaring out wildly, the fabric billowing to reveal the skin-tight suit hugging her massive breasts that heave with every excited breath, her thick thighs tensed in checkered leggings that strain against their powerful curves, and that big, bouncy ass shifting as she bounces on her toes, the jester hat's split red and purple points jingling with bells, her pale face split in a manic grin under the black mask with white lenses glinting mischievously. The double shakes its head vigorously, ginger hair waving side to side in wild waves that catch the dim streetlight, the motion causing her massive breasts to jiggle provocatively under the purple top with its red bat symbol stretched taut.

"I swear.. I-I mean WE swear! I mean... Please, it's me, Barbara!" Barbara's voice pleads through the fused form, her blue eye lens softening with desperation as she gestures with one gloved hand, the cape fluttering like a bat ready to take flight, her thick thighs flexing as she steps closer, that big ass swaying with an unintended seductive rhythm that mixes heroism with chaos. The composite of Harley and Barbara shakes its head again, the jester bells on Harley's half jingling merrily like a twisted alarm, her ginger locks tossing as the red side of the hat flops playfully. "Don't forget me, Harley Quinn talking! We're totes fused, baby! Two sirens, one body—double the fun, double the trouble!" Harley's Brooklyn twang bursts out with glee, her white lens flaring with madness as she twirls the red-and-white striped mallet in one hand, striking a pose that thrusts out her massive breasts even more, the suit's diamonds on her thick thighs catching the light as she wiggles her big ass teasingly, the entire fused figure radiating a dangerous, alluring energy that's hard to ignore. The other half shakes its head once more, Barbara taking control with a determined scowl, her ginger hair settling briefly as she crosses her arms under her chest, pushing up those massive breasts further while her thick thighs plant firmly, the big ass steadying as if ready for action. "You can still tell when I'm talking, right? I just hope dad doesn't find out about this... Commissioner Gordon would flip if he saw me—us—like this, all jingly and chaotic." She glances down at the fused costume, the purple batsuit side clashing with the red jester elements, her voice shifting to a whisper as she leans in, the cape draping over her shoulders like protective wings, her eyes—now a mix of blue and red glints—pleading with you while Harley's influence makes her lips curl into a half-smirk.
