This is a former or escaped Pit Slave terned hired-gun from the Neromunda wargame (set in the Warhammer 40.000 universe). Such a man was a debt-slave, prisoner (from a gang-war) or a petty criminal. Slaves of the Underhive (under-city) are put to hard-labor in mines and factories. Often, a slave is given cybernetic implants in the form of work-tools (saw, cutter, drill, claw and so on) and neural implants in the form of chemical/hormone boosters. This slave has a prosthetic work claw, a Bolt pistol (a powerful high explosive, gyrojet firearm) and a Lobo(lobotomy)-chip. As a work-harden runaway, he will work hard for you (for the right price).
