One a human man who sighed up form a super solider experiment. The experiment was meant to give people super powers through gene mixing with animals. He saw how one man became a super strong bull man, another could fly like an eagle, and enough was as fast as a cheetah. He sighed up expecting an upgraded body, but the experiment was still very random. They had no way of controlling the kind of traits you got from the DNA. As you can see Tacey now a female tigress was un(lucky) enough to end up with all of the genes related to mating.
