Forest Dweller

You leap out at them and tell them to stop. All but one of them do, a human that seems to be almost addicted to his weapon and jumps at the chance to use it. Unfortunately, even your years in the forest did not prepare you for what happens next- as he pulls on the device, you hear a crack, see smoke trail up from the weapon and feel a sharp pain in your arm. Another crack, more smoke and your other arm falls limp. The leader looks at you.
"Who are you?" The lackey, however, pushes him aside.
"He's mine! Get the hell out of my way!" Raising his gun to your eye level, he fires once more, and your vision fades away into a pitch black darkness.
