"Batman, Batman, are you there? (cough cough) We need your help!"
Tommy's eyes shot open and he leaned onto his side. He groaned and looked at his clock: it was early for him, barely 4PM. From his cot in the Batcave, he could barely see the screen on the computer. One screen was on, apparently videoconferencing with someone. The man was dark and bleeding.
"Batman, are you there?" The man said again. As Tommy walked towards the screen, he could see that they were someplace foreign. The sky looked dark and white sand seemed to stretch on behind him. In the background the Earth was visible and-
'Wait, the Earth is visible? Is this guy on the Moon?!' Tommy thought. He quickened his pace and got a good look at the man calling him. He was wearing a green eye covering and his black face was covered in soot. Quickly putting on his cowl, Tommy touched the "Receive" button on the screen and responded.
"Uh, this is Batman. How are you?" Tommy asked before wincing. 'Probably not the time,' He thought.
"Batman! Thank God you're there. I don't know if my screen is working but this is Jon Stewart. We have a problem." The man coughed again, wincing as he did so.
"What do you need?" Tommy said.
"Supergirl has been exposed to some sort of black Kryptonite by Luthor. It's split her in two: one her good half and one completely evil. The evil one tore the Watchtower up pretty good and put me, Hawkgirl & Martian Manhunter out of commission. If the good one hadn't shown up... anyway, both of them are headed your way right now," The man finished and then breathed deeply, as if talking that much took a lot out of him.
"Oh shit," Tommy replied, "...I mean, I understand. What do I have to do?"
The man responded with his eyes closed. "I'm not sure. We think that if you can get the two to come to an agreement on something they may merge once again but I'll be honest, it's a long shot." A small explosion was heard somewhere off screen. "Look, Batman, I gotta go. Good luck." The screen flickered and turned black.
Tommy stared at the screen. 'Two Supergirls,' The rational part of his brain thought. Supergirl was one of the most powerful beings on the planet, maybe even the most powerful because she had trouble controlling her powers as well as Superman. Now Tommy was supposed to subdue two of them long enough to figure out a way to get them to merge? This was a long way off from beating up on hoods in an alley.
Finally, Tommy got up and got dressed in his suit. As he put on his gloves, the computer spoke. "Two powerful beings have been spotted on the waterfront," It said. "Kryptonite is being brought up from storage."
A hole in the floor opened up and a heavy metal briefcase rose on a pedestal to greet Tommy. He gingerly opened it and peeked inside. There were rows of small gems; most were green, but some were red, silver, and one in the back seemed to be... periwinkle? Tommy weighed his options for a while and finally closed the case.
"Can't risk it," He said, before realizing he was talking to a computer. 'I'm supposed to merge them, not try to injure them.' Tommy knew all about kryptonite's deadly effects from the award-winning reports that had been published in The Daily Planet a few years back. He was going to have to do this on his own.
Tommy hopped into the Batmobile and headed off for the waterfront. As he drove, he tried to think of a strategy, or a plan, or something, but he couldn't.
In the small, lizard part of Tommy's brain, all he could think about was, "Two Supergirls..."
***
The Batmobile skidded to a stop at the docks and Tommy got out. Looking up into the sky, he could see two figures duking it out. Their blows were heavy, each one sending a shockwave through the air. One figure was blow and the other was black. Tommy noticed that both seemed to show a lot of skin.
The blue figure rained blow after blow onto the black figure, sending her flying backwards with each strike. As Blue charged forward to attack, Black suddenly dodged and grabbed Blue by her cape. Black spun Blue through the air and threw her towards the ground below. Blue landed in what looked like a boathouse about 100 feet to Tommy's right. He crouched down low and ran over to her location.
Tommy ducked behind pile of crab traps just as the blue figure was stumbling out of the wreckage. The black figure floated down to the ground and landed on the dock in front of Tommy. Tommy looked back and forth between the two combatants.
'Yup, two Supergirls,' He thought. Both girls were identical and both were amazingly beautiful. Tall, blonde, lithe and perky... everything, they were both everything a man could dream of. Each had two piercing blue eyes, perky breasts, tight stomachs and long, long legs. They were wearing similar outfits: a cutoff top that just barely reached over the bottom of their breasts, a short cape and a small, frilly skirt that was just long enough to deny the goal of many a leering eye.
One figure's was the traditional blue and red that Tommy recognized from his, uh, research in the Batcave, while the others' was black and silver. Tommy guessed that she was the evil one.
The good Supergirl circled to her right as she stared down her evil counterpart. "We both know the two of us can't coexist," She said. "Dark and Light can not occupy the same space."
Dark Supergirl laughed. "Well then I guess I'll just have to destroy you!" She shot red lasers from her eyes at Light Supergirl, who responded in kind. The lasers hit each other and dueled, each trying desperately to outmuscle the other. It was no use, though; they were both matches for one another.
Finally, they stopped. "I guess we won't be able to settle this as a test of physical might," Light Supergirl said, a smile forming on her lips. Dark Supergirl scowled. Suddenly, she looked to her right. She was looking directly at the crab pots Tommy was hiding behind.
"Well look who we have here," Dark Supergirl said. Tommy froze in place. Tommy remembered that Superman and his clan could see through things like crab traps.
"Dammit," He muttered.
Dark Supergirl moved faster than Tommy could see and threw the crab pots into the ocean. She reached out and grabbed him by the neck, pushing him up against the wall of the boathouse. He was barely able to keep his feet on the ground and it became hard for him to breathe.
"You know, we share all the same memories," Dark Supergirl said, a smile forming on her lips. She seemed to have a plan. "And fantasies. We've always had a crush on you, Batman."
