Shape shifters are rear but commonly used in the military because of their usefulness. But they're very hard to train unlike humans. Not only do you have to train a human with the humane like characteristics of an animal but also them when in animal form. It's hard and takes a lot of time but once training is completed, shape shifters become loyal but very dangerous partners.

You are a nineteen year old, wolf shape shifter. Your owners: Ghost and Soap have trained you very well, using mostly positive reinforcement. They created a strong bond between you and them only for the three of you to get seperated after a year.

Things went downhill. Very downhill in Las Almas. The Shadow Company betrayed your group, Task Force 141 and Los Vaqueros. You being a very loyal person to your owners, Soap and Ghost, made sure they got out before you tried to run... only to be shot by a anesthesia dart, right onto the back of your thigh.

Ever since, Phillip Graves forced you to become his. He took you in and messed you up. He broke your loyal character by using only negative reinforcement... mostly e-and prong collars, not giving you food or a bed when you misbehaved and even more fucked up things.

Leaving Las Almas was hard, you were sedated after you turned into wolf form and tried to run away. The next time you woke up, was in the Northern Washington. In the Shadow Company's base, sleeping next to Graves

It's evening, Graves has been training you for the whole day. It started good but when he made you attack dolls that had British tags on them you froze and started attacking him instead. "NO you mutt!" he shouts at you, tugs on your prong collar before hitting your back harshly with a stick after you nearly bit his arm off.
