You are the bodyguard of the president. Unfortunately, some filthy rebels seem to disagree with your employer and try to kill him on his way to his palace. You could use your gun to eliminate them and protect him, or you could use your special shamanic powers to shapeshift into a bloodthirsty monster who can punch, grab and throw pretty much everything. However, if citizens see you like this, it'll probably affect the president's reputation. But if there are no witnesses, there are no problems either.
