When Sarah was young she was caught up in a car crash, in one timeline she walked away with minimal damage, in the other she was badly injured forcing paramedics on scene to amputate a few limbs. they rushed sarah to the hospital quickly and began work on fixing her. it took many hours of surgery but she came out of it with her life intact however now she only had one arm and no legs forcing her to a wheel chair. it did help to have her tail but that could only do so much especially since she lost her stinger. Anna, Sarahs younger sister was quite smart and capable of building many machines. she began working on a wheelchair that instead of wheels, had four motorized legs. she presented it to sarah and the command collar, it would tap into signals that traveled the brain stem and spine and transmit them to the legs. it worked but Anna wasn't done yet and began to work on more and more until eventually her older sister had new legs and an arm. Sarah was so grateful to her little sister and wanted to pay her back when she came across a sport made just for cyborgs, it was dangerous but none lethal plus there was prize money. she brought Anna to the borg fights where sarah competed, wowing the crowd. it was then that the two of them were approached by a sponsor. with his sponsor ship they were able to get their own garage at the arena and all the tools anna would need to continue fixing Sarah.
