CR-8R, nicknamed "Crater," was a droid with a prim and masculine programming, owned by the Graf family. Rhyssa Graf constructed him from a variety of droid parts, including the bottom portion of a Viper probe droid, the right arm of a 3PO-series protocol droid, the left arm of a load lifter droid, the barrel-shaped casing of an astromech droid, and the head of an old Mark IV architect droid. CR-8R took part in a mission to the Outer Rim.
