The empty side streets of night time London stretched out around the car. The driver sat in the car, and a tall woman with long blond hair dressed in a white coat leaned against the side of the car. A sword rested at her side, and she was smoking a cigar, lit with a cigar lighter. The woman turned when she heard someone giggling. A girl in a clown outfit walked towards Integra.
"Hiya! Whassup with ya?"
Integra folded her arms impatiently.
"Who the hell are you?"
"Harley! Mister J's gal!"
Integra blow smoke from her mouth, before moving closer.
"Come to think of it, I really don't care who you are. Get out of here."
Harley seemed very angered by this, and suddenly pulled out a knife.
"I'll smash your ass to pieces!"
Harley started to charge, but as she raised the knife, it was slashed in half by Integra's sword, which she had suddenly drawn. Harley stared in disbelief at the broken blade, before throwing it away. Harley then readied a large hammer and charged. Integra jumped back as the hammer hit the ground where she had been. Integra rapidly drew her pistol, while Harley drew hers. Two gunshots sounded, and both women were wounded. Integra had been shot in the left shoulder, while Harley had been shot in the upper chest.
Harley and Integra rapidly charged, Integra readying her sword while Harley readied her hammer, and then both swung at each other, Integra narrowly avoiding the hammer while Harley received a small cut. Harley snarled with rage, and the two women charged again, swinging their weapons at each other. The sound of steel cutting bone and a blunt object breaking bone could be heard all over the street, and the two of them both staggered back. Integra had been hit in the chest with the hammer and had several broken ribs, and Harley had been slashed through the chest and was now bleeding thick red blood from her mouth that betrayed the severity of that wound.
"Goddammit!" Snarled Harley, dropping the hammer and shakily raising her pistol. As she did this, four quick gunshots sounded. Harley looked up to see Integra was leaning on the empty sheath of her sword, having dropped the sword on the ground, and was pointing her pistol at Harley. Harley looked down numbly at the four blood-soaked bullet holes in her abdomen.
"Dammit…"
As Harley dropped her pistol, Integra sat back in the car, telling the bewildered driver to drive back to the mansion. She then quickly called Walter, telling him to have some sort of medical professional there when she returned.
Analysis:
While both Integra and Harley are dangerous, Harley is originally a hospital worker rather than a fighter, and her current fighting more revolves around being erratic than anything else. Integra on the other hand has been taught fencing and shooting, and is excellent at both, as shown when she shot Anderson's bayonets and when she proved able to cut a vampire's head off, a feat that most humans would find impossible.
To top it off, Integra's sword is definitely more dangerous than Harley's hammer.
