Francis Grimes runs the Department of Integration's Law Enforcement Division, and like Twayne, has utter disdain for the immigrants. Preferring to think of them all as "illegal", he hunts down those who have strayed from the proper bureaucratic procedures that provide a path to U.S. Citizenship -- at which point Mark must step in to help. Grimes' encounters with unruly creatures have left him with a lifetime's worth of scars, both visible (missing kneecap) and emotional (broken marriage). Thus, he naturally detests Mark and anyone else who sympathizes with the immigrants. Grimes commands a small but well-funded goon squad that operates out of the D.O.I.'s "force floor."
