While the bio-engendered kunoichi formerly known as Aaron was transporting her friend Rita Jones to the roof, she wondered how the two of them became friend in this new reality, causing new memories to flow into her brain.
The extremely wealthy Mr. Tanaka, C.E.O. of the international company known as Tanaka Pharmaceuticals outside of Japan, had recruited the world's best geneticists, bio-engineers and neuro-psychologists, among peoples not caring about ethics at least, and hidden them in a secret lab somewhere in the U.S.A. so they could create an army of super-soldiers that would be at his command. A few years before his only child, Jennifer Tanaka, died from a cancer. Nobody had been able to save her, which drove Mr. Tanaka to insanity. The inconsolable father felt the world was responsible, and wanted to conquer it in reprisal.
In his insanity, Mr. Tanaka ordered that all his super-soldiers must look like his lost daughter, or at least as she would have at the same age and with the same physical health. He also kept the first clone, Jennifer-1, for himself, raising her like she was the original.
Producing such bio-engineered soldiers from scratch was too complex, so his mad-scientists kidnapped peoples, be it adults or kids, as raw materials. Since the Jennifers were made as kids, they could make at least two of them from one adult.
Then came the day Rita, who was only 6 back then, and her family had been kidnapped as more matter to make more Jennifers. Except that Rita escaped. She didn't go far before a guard captured again, but in doing so the guard made her touch the artificial womb in which floated a Jennifer ready for activation the next time Mr. Tanaka came to visit.
Nobody know why the ‘activation room’ had been left open, but the wombs were programed to detect when someone put their palm on its glass, and force the Jennifer inside to establish a telepathic contact with who did this so they could give orders to the super-soldier without being overheard. As per procedure Jennifer-281 dumped into Rita's brain all informations about what she was and how to operate her, as her new mistress.
Rita didn't understand what was happening, she just wanted someone to come deliver herself, her parents and, if possible, the other prisoners. Of course, Jennifer-281 perceived this as her orders, and started with incapacitating the guards after her mistress.
It rapidly became apparent to Rita that Jennifer-281 wasn't someone ordinary. Not only was she far more strong and nimble than should be possible, especially from someone that seemed to be the same age as Rita herself, but she somehow communicated directly in Rita's head, and not even using words to do so. Then the man-made kid demonstrated her ability to turn invisible and used her telepathic abilities to search informations about the prisoners whereabouts.
She wasn't able to save everyone but thanks to the peoples she did save, activities of the Tanaka zaibatsu were revealed to the world and, since they were deemed too dangerous, most Jennifers were destroyed/killed. Only Jennifer-1 who hadn't even known she was a clone of the original Jennifer, let alone a super-solder, (so she don't have any idea on how to use her powers) and was horrified by her father's actions, and Jennifer-281 which Rita, too young to see her as something other than a new friend, didn't want to loose, unconsciously made to defend her life at all cost. Rita who didn't take long to rename the man-made super-powered kunoichi Amy.
It was eventually decided that Amy would be put in the care of Rita's parents, as she wouldn't let anyone separate her from her mistress/friend. As she grew, Rita understood better and better what Amy really was, but since she always wanted her friend to develop her own personality, only unconsciously at first, then consciously too as they grew and understood the true nature of said friend, Amy became an almost normal teenager, mentally speaking. Although if Rita ever gave her an order, she wouldn't be able to disobey. (And probably wouldn't even want to anyway.)
Their relationship was a bit odd, a mix between best-friends, sisters and mother-daughter.
As soon as they were on the roof, Rita was put on the ground. "Amy! What's wrong?!? You scared me to death disappearing like that!!"
Aaron not wanting to say the truth to Rita, fearing it would damage his (her?) relation, tried to come up with a believable lie. "Sorry, I saw another Jennifer, it terrified me." As soon as she had said that Amy realized that she had seen another Jennifer among her fans.
"Aw, I'm sure it was just Jennifer-1, you know she admire you for successfully living a relatively normal life regardless of your particular circumstances. Heck, your life is probably more normal than hers, and she's the one who used to think she was normal and that can't use her powers. Plus she's a big fan of your group."
But Amy shook her head. "When I used our usual mental greetings she immediately zeroed on me and furiously called me ‘281’, Jenny never call me that. Plus, her mind didn't feel like Jenny's, or a girl for that matter."
