"You're not going anywhere Harley!"
"Yes I am!"
"Dammit Harley, close this portal before who knows what comes crawling out!"
"And who's gonna stop me Bats? This portal leads far far away from your precious Gotham, into anotha dimension even, so I'll be out ya hair!"
After those words, Harley Quinn disappeared in a brillant flash of light, the portal closing behind her and leaving Batman punching the wall of the warehouse in anger. "Son of a bitch... I hope she'll be ok...", he muttered to himself as he hopped back into his Batmobile back to the Bat-cave.
 
After another brillant flash of light, Harley found herself in front of a large, beautful house at roughly midnight. "Well damn, whoeva lives here sure makes the big bucks!" she said to herself, looking around to make sure nobody spotted her. "Would be a real shame if some psycho bitch broke in and-" her words being cut off by her stomach growling, louder than she's ever heard it growl, "Quiet you! Don't need ya to wake the whole damn neighbahood!". After some fiddling about with some of the windows, Harley found herself inside the house, chuckling to herself and rubbing her belly, thinking about what she was gonna go eat after she gets some cash. She skulked about, thinking more and more about her hunger, her stomach growling more and more until her thoughts were stopped in their tracks by a bloodcurdling shriek followed loud slurping and finished off by a bellowing belch.
 
Harley, clearly shocked but also curious by the event, crouched down and quietly walked over to the living room where she found a large, squirming, fleshy orb. "That's one big belly!", she thought as she gently put her hand on it and rubbed it, causing the giant gut to squirming more and the owner of said gut to let out a massive belch. "Whoever you are -burp- tell me who you are or you'll be my second -belch- course", said the woman pinned under her belly, her hand tightly gripping Harley's. "My name is Harleen Frances Quinzel but you, Large Squirming Belly, can call Harley Quinn!" Harley exclaimed proudly and without fear, much to the woman's surprise.
 
"Ugh another Har-UUURRP-ley Quinn cosplayer? Jesus Christ, I'm sick of you people, at least you're dressed in her original outfit, not that it changes much" the woman grumbled as she proceeded to sit up. "Cosplayer? Who the hell is runnin around, dressin like me? I'll kill em!", pulling away from the woman and lifting the nearby table up above her head with one arm and the other lifting a nearby recliner. "Wow strong girl, might make a -burp- tougher meal.", the woman stated, her blonde hair covering her face before being brushed back, revealing her beautiful face. "Or you could just not eat me, tell me where I am and I'll be on my merry way." Harley responded, entirely unimpressed by the woman's threat of making her another course in her feast.
 
"Don't you know who I am?"
"Lemme think... nope!"
"Seriously? You dress up like Harley Quinn and don't even know who I am?"
"Should I know or care why? Listen lady, I'm the real freekin Harley Quinn and I could beat ya ass 18 ways ta Sunday! I've fought Batsy enough ta pick up on a few tricks so bring it on Blondie!"
"...ok now I'm confused, no cosplayer I've ev-URP-er seen would keep this stupid charade going and would've asked for a picture by now or something and they DEFINITELY can't lift a table and recliner like little -URRP- toys so either this is a food coma fever dream or some way, somehow, the REAL Harley Quinn came to this universe."
 
Harley was fed up after this exchange, throwing the table and recliner aside in frustration. "YES, I'M DA REAL HARLEY QUINN, HOW MANY MORE TIMES I GOTTA DRILL THAT INTO YA PRETTY DUMB SKULL?!" Harley shouted, "I jumped through a portal running from B-Man and I ended up in front of ya damn house now will you kindly tell me who you are, why the hell I should care and where the hell I am so I can leave and get myself some food, I'm STARVING!", her belly growling loudly as if on cue. The woman was shocked, the REAL Harley Quinn was standing right before her very eyes, she couldn't believe it. Taking a moment to composure herself, the woman spoke.
 
"Robbie", she said, "Margot Robbie."
