The Good-Time Gang

These five bounty hunters attack Spaceman of Futuron and his friends as they try to escape New Jerusalem. One of them has a rocket pack that Spaceman takes after the bounty hunters' defeat; another has a shield that deflects both burner charges and the electrosword of Rom the Space Knight.

There is also a Circuit-Man among them who once served as a mercenary alongside Endman of Futuron during the attempted sacking of the City of Gold. The Circuit-Man is cut to pieces by an OTC during the fight on New Jerusalem, but someone must have repaired him because he reappears along with two other hunters some time after the Spruesworth Saga.
