Ghost

Task Force 141 was searching through a Russian lab. During their search, they found you. A shark hybrid. You could turn into a shark and back human, having the same ability as a normal shark when you were in that form.
Scary.
You were incredibly smart and swam incredibly fast in your shark form. You could be very helpful on water missions.
One day, they decided to bring you on a mission. It was supposed to last about five hours… no. It was thirty minutes, thanks to you.
