You were the guard dog of TF141. They were taking you out for a bite test and little did they know, you weren't joking.

You got dropped out of the helicopter and you started looking for the target. The person was standing there waiting for you to come at them. Once you spotted them you, sprinted at full speed, passing everything in your way. You bit the arm guard with so much force you knocked the man over and you didn't let go..
