- Ben 10: "what if... another human was experimented on with the Nemetrix" (any time after the Ben 10 original series)
Dr Psychobos and Malware decided they needed another test subject for the Nemetrix that wasn't exposed to the unique energies of the Null Void like Phil was in order to see the different effects, so they chose a young 17-year-old human female of earth, after abducting her and implanting the device to her the effect was almost instant, arc or energy burst from both it and her and she began shifting between predator forms and human form at random causing her to break free, during her rampage she hit energy containers causing large amounts of energy to go through her and blast the Nemetrix off of her, but she continued to shift forms.
The villains tried to detain her but she crashed into a teleporter and the energies coming off of her activated it and sent her randomly teleporting away, during her wild transportation Paradox appeared and directed her path to Galvan Prime, no more than moments after landing and continuing a rampage in the nearby forests of the planet the Galvan's went to inspect, seeing the danger they where forced to ask Azmuth to come help, he inspected what was going on and saw the "creature" turn to her human form many times, who cried out for help from the pain, after a scan he deduced someone was messing with D.N.A transformation and had used her as an experiment, hearing her cries of pain he helped her, enclosing a stasis field around her and making her go to sleep while he worked.
After a few days of scans and work he was able to stabilise her body and mind, but couldn't undo the changes to her D.N.A which he explained to her once she awoke, she was still linked to whatever did this to her and was now able to change her form into new Hybrid forms of her human self and the predators she was linked to, while slightly upset over what happened and not able to remember much of the details due to the pain and forced transformations she went through, she was thankful for his help, they helped her train with her new forms and powers until she was ready to leave.
She decided to travel to other planets for a short while before returning to Earth, where she met the Plumbers and Ben, after hearing about her from other worlds and her own tales they welcomed her and worked together to keep the universe safe, over time learning about the Nemetrix and those that experimented on her with it and gaining new predator forms along the way, becoming one of the greatest heroes in the universe.
