Prototype: 03

After katana's creator became on the run with her, they are soon cornered by military and more. In the mass massacre, Katana took a full attack of a missile for her creator after a desperate attempt to kill off the doctor, growing her size to shield him from such a blast. Though her creator lived, there was nothing left of her body to survive though her creator stored her soul with his abilities. With no lab at the time, he went to his Father in hopes to gain the help of his mechanical engineering. With ease and success, Prototype: 03 was born.
