That one guy who flies on a verto-gunship, shooting rockets at critical targets, spamming bullets in player's direction, and playing a kickass theme tune while doing it. When he shoots down a gunship, i eject and parachute into the valley below, not noticed by him.
Somewhere down the line, a missle barrage inexplicably appears and saves the hero from almost certain death. Helpful airdrops appear seemingly out of nowhere. Enemy ammo storage is blown up before hero can even look at it.
And when after the fight final boss fakes surrender and tries to ruin the hero's day by killing him, i appear and shoot him. Why? Because apparently that douchebag wanted to get rid of me by ordering me to take on a hero. So fuck him.
