There is an exstensive number of recurring inmates. While not all inmates are named, or have speaking roles, many with distinguishing features reappear throughout the series. Many are just filler designs used in the background to fill space, but can also become piviotal characters in other episodes. Little continuity is present, as an inmate can be killed in the psychodelic bloodbath at the end of an episode, only to return unharmed in a later episode.
