Making a quick and admittedly impulsive decision Karley heads out jumps off her balcony letting herself hit terminal velocity and almost the ground before flying off. She laughs madly going at incredible speeds almost hitting a few planes reaching Gotham in seconds. Thinking about it she breaks into bed store and takes the romantic heart shaped bed.
Bed in hand she proceeds to knock over various romantic stores Karley gathers up everything she'll think will be romantic. Taking all of her stolen goods she b-lines it to the batcave and sets everything up. After seeing Selina off Batman and Alfred return to find the Batcave covered in rose petals leading to a heart shaped bed. Following the trail they see an extremely busty blonde dressed in reavealing black and red lingerier lying seductively on the heart shaped bed.
"Heya Bats come and ride you Karley she needs a tune up." Karley says winking.
"Harley how did you get in here?" Batman asks.
"Who's this Harley chick cause there's only one Karley Quinn and she wants her big bad bat." Karley says lunging at Batman.
Easily dodging her Batman turns around to see her just floating there. 'Since when does Harley have powers.' Batman notes before taking note of her facial features. 'And look like Powergirl?'
"Powergirl why are you dressed like Harley Quinn?" Batman asks her."Who's this Powergirl and Harley broads you cheating on me.!" Karley yells. "Well as far as cheating when we just have casual sex amazing casual sex. Look Bats thought you'd be more into this I mean you got me here all sexy and ready to fuck but no you're all talking about other chicks guess I'll try to find Red."
"Poison Ivy's also missing?" Batman asks.
"Oh yeah did a quick look couldn't find her was gonna check Arkham next." Karley says as she starts packing up her stuff.
"Wait Karley I'm investigating the recent disappearances and I would appreciate your help." Batman tells her.
"Really you want my help to find Red awesome oh I'll go put this stuff away we can always use it later." Karley responds using her superspeed to clean up.
"Are you sure about this sir?" Alfred asks.
"No Alfred but something has apparently fused Harley and Power Girl together and right now she's our only lead." Batman states preparing himself to work with a super powered Harley Quinn.
