R5-D4 has a White body, with mainly Medium Stone Grey printing, white 'legs', and a plain white dome. R5-D4 also has a Brick-Yellow 2x2 round plate in between it's body and dome, making R5-D4 taller than other Astromech Droids.
He was once in the possesion of Jawas led by Nebit, and then sold to Owen Lars. R2-D2 was given orders by Princess Leia to get to Obi-Wan Kenobi under any means necessary, so R2-D2 (supposedly) wrecked R5's motivater so R2-D2 could get off the sandcrawler and find Obi-Wan instead of R5-D4 getting off. After R5-D4 malfunctioned, he was replaced by R2-D2 under the suggestion of C-3PO. The droid was stolen by a Squib as a rescue before the sandcrawler was damaged and killed the Jawas and Nebit and the droids malfunctioned after Sandtroopers came.
- R5-D4 is the only Astromech Droid to have an unprinted dome. (First Variation Only)
- It is also the only Astromech Droid to have a 2x2 round plate in between it's body and dome. (First Variation Only)
