often simply referred to as Red, this Industrial Automaton droid was one of the last R5 units ever built. Red was purchased by Owen Lars from the Jawas, just before he purchased C-3PO. R5-D4's motivator (or servomotor-central) blew just after purchase, so Owen ended up buying R2-D2 instead. The Star Wars Radio Drama explains that R2-D2 modified R5-D4 so that its would motivator would fail, drawing attention to himself. R5-D4 then spent a number of days riding along inside the Jawa's sandcrawler, until the sandcrawler was attacked by Imperial forces looking for R2-D2 and C-3PO. R5-D4 was in no condition to move, and bided his time until another group of Jawas came by to claim the left-over machinery. R5-D4 made it back to Mos Eisley, where he was purchased by Voren Na'al and reprogrammed. With the help of Momaw Nadon, Na'al sold R5-D4 to the local Imperial prefect's assistant administrator. There, R5-D4 recorded everything is heard and saw, holding the data until it could be recovered by Nadon. After the Battle of Yavin, it was rumored that R5-D4 had some sensitivity to The Force, although this was never proven. There was a story of a Jedi droid named Skippy that matched R5-D4's description.
