R2-A5 is an Astromech Droid minifigure. He was present in the streets of Mos Eisley during Episode 4 of Star Wars.
R2-A5 is mainly white with green highlights on his dome and body.
R2-A5 was never labeled anywhere as R2-A5. However, it can be safely assumed that the astromech droid is indeed A5 as the color scheme and droid type are the same.
