After being killed in the crossfire of an Autobot vs. Decepticon battle, the young girl's body is taken by MECH and is reborn as Ace (Altered Cybertronian Experiment)

Cat - short for Cathleen - officially hated the world. For all she cared everyone and anyone could die, until that was exactly what happened. People left and right were dieing in her home town, starting with the kids in her grade. In fact, anybody who had ever said something mean to her, were being killed. And the most strangest fact yet, was that she was getting black outs, bad ones. The black outs started getting worse and lasted for hours, and all she could dream about was the death of her bully's. At least... She hoped they were dreams. The secret Cathleen didn't know was that SHE was the reason people were dying, the black outs were really CAT coming out to play. And that CAT was slowly going to make the entire town red with the blood of its civilians. The creepypasta was coming, and they weren't very happy with CAT at the moment, but they need her with them, so they could keep an eye on her.
