One of the very first characters I designed for the project some 3 or more years ago, even before Arkham Origins.
Years of teaching Industrial Arts at one of the United States' roughest high schools taught Bushwhacker several key lessons. Firstly, never take anyone else's word on whether a weapon is loaded. Secondly, anything can be fixed with enough duct tape, time and cigars. And thirdly, if you're going to face death every day, you may as well get paid danger money for it. And while education is your passport to the world, as it turns out, designing and deploying your own patented auto-turret is even better.
