Replicator blocks, elements of the sentient electromechanical race first created as a toy by the android Reese. In various forms, Replicators would threaten organic life in two galaxies for years, and prove remarkably resistant to attempts at their elimination.
Red and charcoal-painted resin blocks, in standard and unusual shapes, individually and in groups, as seen in early Replicator SG-1 episodes including fourth season opener Small Victories.
