Zhendi
There once was a 'mad scientist' who worked in an underground laboratory. He took dogs from the city streets above, and brought them down to use as guinea pigs. He created some horrible, and some fantastic things. Zhendi, a young german shepherd who lived with her owners in a street nearby, was on her evening walk one night, and decided to take a slightly different route. It lead her through an alley to a dead end. She turned and began to head home, when something sharp hit her side, and she collapsed.
Zhendi was changed in that lab. And all she wanted was to go back to her owners. She suffered, she felt pain like never before, And she grew stronger. Harder. Until she no longer remembered who she was, or what she wanted.
