If you play Traveller, especially Classic Traveller, Mongoose Traveller 1E or Cepheus Engine and you don't want to wait around for your players to kill off a few hundred characters for you to turn into NPCs, then give this a look:
Cepheus Engine Supplement 1: 1,000,001 Characters

Be sure to read the side-bar instructions as it contains some cool extra usage tips ... such as how to tweak the settings and generate hordes of minions...
It also also pretty easy (and permitted!) to harvest the javascript and host it locally.
@ELF might even be able to turn this into a CL generator given the open permissions on it
