R2-A0 was a feminine-programmed brown and white plated astromech droid that was built as Red Sears's astromech droid. She was built during the second Galactic civil war and was used as a copilot for rebel pilot, Kero Reak. She was destroyed along with the plans for thousands of New Republic attacks. She was later found and rebuilt by New Republic pilots and was given several new features and more memory.
