We all know about the infamous Joker, the mad clown that terrorized the city of Gotham. But what we never knew about was his accomplice, his frighteningly beautiful and highly deadly pyromaniac baby doll, Harley Quinn. The Bonnie to his Clyde, the brains behind his brawn, and most importantly, the love of his life.

"Ha ha ha. Ha hee hee hahahahahaaa…"

Even as the Joker was left hanging upside down by his ankle swinging around a thousand feet above the ground below, he was still cackling at the top of his lungs. The SWAT team that arrived could only stand and stare in awe at the mad clown dangling before them. When two of the officers reached to grab ahold of his arms, he withdrew a knife from within his coat sleeves in each hand and slashed them through the air. The blades sliced through the palm of one officer and through the wrist of the other. Immediately, the officers all opened fire on the Joker, each simultaneously firing a single shot in his direction. Unfortunately for them, he had swung back as they all shot at him, allowing the bullets to whiz by him. One bullet was able to strike him, grazing his right forearm, ripping open his flesh down to the bone. Instead of screaming in pain, the crazed clown laughed even louder.

"OHH WAHAHA! OOH HOO HOO THAAT TICKLESSS! AHAHAHAHAHAHAHAHA!" he screeched.

As one of the officers phoned in an ambulance for the two bleeding men, both gripping their maimed flesh, squealing in pain, they heard another cackling somewhere nearby. The team turned around, guns raised, but saw no one else there. From behind them came a soft thump. All the officers immediately turned face left towards the source of the sound. Laying on the ground was a small black box, tied up loosely in a red ribbon. One of the officers stepped closer up to it and carefully pushed off the lid with the barrel of his gun. Inside there was a piece of paper folded in half over a fist-sized bundle at the bottom of the box. He picked the paper out from the box and unfolded it. Written in the center of the paper in pencil was one word, 'BOO'.

"What is it?" one of the other officers asked as he and a few others stepped closer. As they did, the box exploded with such force it sent those men soaring clear off the edge down to the ground below, causing the Joker to laugh even harder as he watched their bodies splat against the concrete. The explosion temporarily blinded the other officers. When their vision returned after a few seconds, they couldn't believe what they saw.

Standing before them on the edge of the building, her left hand casually on her hip and the other behind her back, was what appeared to be a female version of the Joker. Her face was painted white with her eyes sockets painted black, and dark red lipstick smeared over her lips and across her cheeks in a clown grin with red spots on the corners of the painted smile. The left corner of her mouth was curled up in a half-grin under her frightening make-up. Strings of greasy blonde hair fell over her face from under the hood of her sleeveless hoodie which had a red and black diamond pattern, a black wife-beater worn underneath. She was wearing a plaid skirt that matched her hoodie, being red with black grid lines, and on her feet were a pair of black Converse shoes. On her legs were fishnet stockings, and on her hands were a pair of fingerless black leather gloves.

The SWAT team raised their guns to her, the lights on their guns shining directly on her, allowing them to better see the soot coating her clothes.

"Freeze!" they ordered, "Put your hands in the air!"

The clown girl cocked her head to the side and said, "If you insist." before raising her hands. As she brought her right arm up from behind her back, a large ring-shaped leather strap flew off her hand, landing on the floor and sliding across, stopping just an inch in front of where the men were standing. On this strap there was five grenades attached to it. They looked up to see the girl giggle and shake her raised fingers on her right hand. On each finger was the ring to the grenades. Before they could even react, the grenades exploded, blowing them all away, leaving the Joker squealing giddily and clapping his hands with an almost childish delight.

The girl licked her teeth as she looked at the smoldering remains of the SWAT team laid around her as she walked over to the dangling Joker.

"Well hellooo baby doll." he purred, licking his lips sensually.

"Hi there puddin'," she responded in her soft Boston accented voice, "Did ya miss me?"

"Ohhhhh you know I did."

When his body swung closer, he reached his arms out to her. She eagerly grabbed them and pulled him closer so she could give him a brief but passionate kiss on the mouth.

"Now," he said when their kiss was broken, "how about getting me down from here, huh?"

The girl gave a light titter before she pulled the Joker's arms around a vertical beam. "Hold on tight now." she told him before she hopped up and clasped her hands on the edge of the floor above and kicked her legs up and wrapped them around the base of the beam of the above floor like an acrobat, allowing her to hang upside down as she held onto Joker's free ankle while she worked on pulling apart the claws on the grappling hook clasped around the Joker's other ankle. Once the claws came apart wide enough, his leg finally fell free. When it did, she pushed his legs towards the inside of the building, allowing him to land safely on the floor inside on his stomach.

Once he was lying face-down safely on the floor, he flipped himself over onto his back. After a heavy sigh and a lick of his lips, he pushed himself up on his feet and stood upright, licking his lips some more as he watched his girl swung down, gracefully landing on both feet before him. He walked up towards her, his black shark-like eyes gazing up and down over her beautiful tiny body like a hungry wolf. He stopped just an inch in front of her, looking down into her hazel eyes that were just four inches below his own, then gripped her slim waist and pulled her up so he could crush his mouth against hers, shoving his big tongue past her lips and inside her mouth. As he pushed his tongue further and further down her throat, she responded by pushing her own tongue into Joker's mouth, knotting her fingers through the Joker's stringy green hair, gripping it rough and giving a light, but sudden, tug. This caused him to illicit a low moan as all the blood in his body rushed down into his groin. The girl chuckled into his mouth and ran her other hand down his chest and stomach, rubbing her palm over his fully grown hard-on.

At this touch, he pulled her face away. "Ahhhhh, youu little mynx." he sighed. The two then joined hands and waltzed across the room together, stomping their feet in the charred, gory entrails splattered on the floor as they spun round and round together, moving towards the elevator shaft.

"Shall we?" the Joker asked, tilting his head down towards the open shaft, his hair falling over his face.

"Ladies first!" she sang, with a nod. After giving her answer, she hopped down through the shaft, wrapping her hands around the tether and sliding down it like a fireman. The Joker himself soon followed, sliding down the other tether after her, cackling with mad delight. The girl landed on the ground floor first. Upon her feet touching the ground, she released her grip on the tether, allowing herself to fall backwards and land on the palms of her hands. Once her hands hit the floor, she raised her legs up, executing a perfect reverse somersault. The Joker landed just in time to watch her land with perfect grace on her feet.

At the same moment the Joker stepped away from the tether, an ambulance arrived with blaring sirens, stopping just in front of the open doorway.

"Oh look pumpkin," the girl said with another half-grin, "our ride is here."

The Joker tossed her a knife as two then ran up to the truck, the Joker standing at the driver's door and his girl standing at the passenger's. Both the doors were opened on either side by the two paramedics officers inside. The two men both froze at the sight of the clowns grinning up at them. Before they could react, the girl-clown swiftly stabbed him in the throat right through the jugular, leaving him bug-eyed in terror, clasping him hand around his neck over his wound, gagging as his windpipe was flooded with his own blood. She grabbed him by his arm and pulled his body out of the truck, shoving him to the ground and hopping inside in his place. When she plopped into the seat, the driver spun his head back and forth between the two clowns on either side of him.

"What the hell?" he exclaimed, his turkey-neck jiggling as his head turned, "Two of them?"

"That's right big boy," the clown seated beside him giggled, "Double the trouble." Upon saying this, she sliced through his fat neck, his loose skin dangling wide open, allowing the blood to flow down his chest and over his fat gut, which the Joker sank his own knife into to the hilt, dragging it across his body from one side to the other, causing his entrails to spill out all over the seat and floor.

"Hahahaha. Now get the fuck out lardo," she laughed wickedly, shoving his heavy body off his seat and out of the ambulance, the Joker sliding out of the way for the man's still barely living body to splat onto the asphalt, "It's my turn to drive."

"At-at-at-at-at-at-at, not so fast doll-face," the Joker chastised, pushing her into the passenger's side as he hopped up into the driver's seat, slamming the door shut, "I'm drivin'."

"Fine." she huffed, slamming her door shut and crossing her arms in reluctant defeat.

"Awwwww," the Joker cooed, holding her chin in his thumb and turning her head to face him, "Come on baby girl, smile for me."

Of course, she could never stay upset at that handsome scarred face of his. The left corner of her mouth turned up in a half-smile, while the melted right half of her mouth left it in a permanent grimace, masked by her painted clown grin.

"Thaaat's better." he purred.

He then put the truck in drive and hit the gas, peeling the ambulance down the street and onto the highway, sirens blaring. The sirens made all the other cars veer off to the sides to let the ambulance pass, but that didn't stop the Joker from steering side to side, smashing through one car after another, the two clowns cackling and slapping their knees, entirely amused by the carnage they left in their wake.

Here's my attempt at bringing Harley Quinn to the Dark Knight universe :D

this story serves as a sequel, but mostly as a prequel, displaying the relationship between these two mad clowns ;)~

inspired by and dedicated to my delightfully mad boyfriend Joker =)3
