Your character is a hybrid, part human, part animal. He/she is a subject of human experimentation, and held deep within a secret military facility. The program he belongs to is focused on creating living weapons by splicing humans with animal DNA to create creatures with superior strength, reflexes, and senses to a human and superior intelligence to other animals used in war, but that can still be easily controlled by their handlers. They will have to learn to work together and control their animals before they can rejoin society.
