A hunter-warrior is a bounty hunter in the Scrapyard who is registered with the Factory. This makes them eligible to pursue wanted criminals and collect the bounties on them. Because there is no formal criminal justice system or police force in the Scrapyard, hunter-warriors function as the primary means of enforcing Factory Law. However, they themselves are still subject to Factory Law, and can become wanted criminals when they step outside its boundaries. Notable hunter-warriors included Alita, Daisuke Ido, Clive Lee, Murdock, and Zapan.
