Thy was created in a lab as part of an experiment to clone a Thylacine (Tasmanian Tiger) as a way to bring the species back from extinction. Unfortunately the DNA sample that was to be cloned was contaminated with a human hair... so instead of creating a Thylacine like it should have the DNA created a Thylacine-Human hybrid. The Scientists named the strange creature Thy. Thy is the world's only marsupial humanoid, so she has a pouch - and that's cool :3 She also has backwards facing knees and a tail - and that's really cool :D

So in the end the scientists failed to create a viable Tylacine and the funding for their project was withdrawn. Thy was taken by the US government (who funded the initial project) and trained in the military to be an ultimate killing machine. Thy learned to kill without remorse and soon became a super weapon capable of lethal precision. And so the military used Thy throughout the years to covertly kill high ranking criminals and political figures in foreign nations. But then Thy was ordered to kill the innocent, people who had witnessed atrocities committed by the military she was working for. Thy rebelled and refused to kill the innocent.

Deemed a potential threat to their security, the military threw Thy into a cage in the basement of the building in which she was created. She remains there to this day, cold, frightened, and alone. :( but it doesn't have to end there, I will save her one day.
