This will be an AU one-shot collection. The one-shots will be set in this universe I created where Alex is Batgirl and meets Kara as Supergirl. The idea is that Kara and Alex are fated to meet each other one way or another as they are platonic soulmates. This first chapter is mostly an introduction to the universe, the chapters that follow will be more relationship-centric around Batgirl and Supergirl.


Life growing up had been quite uninteresting for Alexandra Danvers, an award-winning scientist, and doctor. Years later, she would even state so in her autobiography. In fact, one would even say her childhood had been the perfect picture of formation for her success. In those times, marriages were commonly failing, and split families, with children, was commonplace. In contrast to the widespread rise in divorce in her culture, Alex's parents, Jeremiah and Eliza Danvers, stayed happily married, even to this day. Alex had also been an only child. Any free time her parents had, they had devoted it to her. She received all their attention when they could give it when she was growing up, contrasting with her school peers who had siblings. Her whole life was set up for her to succeed, statistically anyway. Nevertheless, an immense part of her success had been her uncanny interest in science and medicine. She may have had the 'perfect' life, the 'perfect' upbringing, but her own ambitions and talents are what made those circumstances into being the statistic that they are categorized as. Namely, the statistic for if a person will be successful.

The twenty-something doctor and scientist sat studiously on her stool, a microscope pressed to her face, and her auburn hair tied back into a short ponytail. A white lab coat sat snugly on her frame, the cuffs not too long nor too short for her arms. It was a minor detail that spoke of coat's high cost. A photo-ID pass was clipped to one of the coat pockets and swayed ever so often when her fingers adjusted a knob on the sleek microscope. The ID was an all-access card, one she wore with pride. The lab, her lab, was a grand sight to see. Only the most innovative technology was at her disposal—that was the luxury with working in the private sector. Even more so when you're employed by Wayne Industries. The Wayne Industries.

Wayne Industries, Alex would never have dared to envision working for Wayne Industries, or even coming up on her one-year anniversary of employment with the corporation. Formerly, she had wanted to be a doctor in a hospital. However, as much as working in a hospital would give her an opportunity to save lives, she found her love was in experimental medicine. Wayne Industries, after she published a paper on an innovative cure for Cancer, recruited her into their ranks. After receiving the job offer, she promptly quit her job at the hospital in New York City and moved to Gotham. Gotham and Wayne Industries offered her what public medicine could not—funding for research into experimental medicine, as well as funding for other experimental pursuits.

Dr. Danvers, still engrossed in her work, unaware of her surroundings, scribbled down notes on the chemical reaction she observed on the slide in the microscope. This project was specifically assigned to her by the Bruce Wayne.

Curiously, the green luminous mineral she examined, combined with the blood sample she had been given, gave off a strange reaction. The blood itself heated up in temperature, almost as if it was under a heat source. It was a very curious phenomenon. The blood sample, the red blood cells, had a very different structure than anything she had ever seen before. The cells were hexagons instead of the average plate-like structures.

Our millionaire vigilante owes me answers, Alex thought as the blood came to boil from contact with the green mineral.

Oh yes, she knew. Bruce and the Batman were one in the same. It hadn't taken Alex long to figure it out. Especially, with Bruce giving her peculiar side assignments, ones that matched too much with later Batman activity to be a coincidence. Then again, it hadn't taken Bruce long to figure out who was anonymously giving the police forensic samples to help in their criminal investigations, among other nightly activities Alex had taken up in her spare time.

Writing diligently in her notes, she scrawled out, 'red blood cells seem to deteriorate upon contact with Element G.' Element G being the designation she had termed the mysterious element Bruce had given her. The luminous light, the non-toxic radiation, it gave off was itself a conundrum, nevermind Bruce adding a strange blood sample to the mix. Element G, Alex knew was not anywhere on the periodic table—it could be new earth element. It could be a monumental addition to the periodic table, Alex knew that was wishful thinking though. Batman business rarely ever resulted in award-worthy academic achievements or at least ones that could be announced to the public. This was likely a classified discovery.

Brow furrowed in contention, she placed Element G back in the lead-lined container Bruce had delivered it in. Peering eagerly at the blood sample under the microscope again, she watched in wonder as the hexagonal blood cells rapidly repaired the deteriorations they had contracted from contact with the green substance.

If she had to guess, the blood sample had to be from some meta-human. Maybe the Flash? Black Canary? The sample was a medical miracle, a medical gold-mine in terms of treating cancer, and any number of diseases. If she could replicate the process she just watched the blood sample execute but with organ cells, she could stop the decay that is derived from cancerous cells. She could regenerate cells back into their original state. This could replace chemotherapy as the common method of treatment with cancer cells, and it would be a less invasive procedure of medicine.

Alex's eyes shined with wonder as she wrote down as best she could the process of cell restoration that she had just witnessed—

SLAM—CLANK—

Alex grabbed the blade she kept hidden beneath her work pants and seamlessly withdrew the weapon. She rolled away from the abrupt sound and took a low offensive stance directed where the sound had originated.

Oh yeah, did she forget to mention she was Batgirl…

"Pay attention to your surroundings," A brusque voice demanded from her window. A shadowy figure, he sat posed on the open window frame, his right hand firmly holding his anchored grapple. His dark mask was adorned with pointy ears and his eyes were covered with white lenses. Beneath the mask, she felt his eyes had great displeasure at her lack of attentiveness. "If I had been the Joker, you could've been blown to bits," Batman grounded out, teeth grinding together in his displeasure. "At least, make sure your window is locked," he curtly finished, his white eyes taking stock of Alex's fighting stance, it was one he had yet to teach her.

"Come on, I have a lead about a potential Penguin sighting," Batman said civilly, his tone now gracious toward her, and he turned to look out on the city indicating the direction and place of meeting.

Welcome to Gotham. I'm Batgirl and using just my index finger, I know six different, very painful ways, to get a confession out of a man.
