From the pages of 2000AD
Following the Atom Wars in the 22nd century, many of the survivors were mutated by the Strontium 90 fallout. Unable to get regular jobs, forced into ghettoes and considered an underclass by the ""norms"", the only work open to them was bounty hunting. These Search Destroy Agents - or Strontium Dogs - hunt the criminals too dangerous for the Galactic Crime Commission. One such S/D Agent is Johnny Alpha, whose eyes enable him to see through solic objects. Book 4 collects together such classic stories as Bitch and The Stone Killers.
