R2-D2

The blue-domed astromech from Naboo's royal hangars has one professional distinction no organic in the war can claim: he was never once wiped. Every rescue, every betrayal, every secret from the Queen's starship to the second Death Star lives intact in that little memory bank, which makes the galaxy's most underestimated figure also its most complete witness. His service record reads like the saga itself, because it is: patched a queen's ship under fire, flew as Skywalker's co-pilot through two wars, carried the stolen plans and the desperate message that started a rebellion, and hauled a lightsaber out of a swamp when destiny needed a courier. He argues with protocol droids, lies when it helps, and gets forgiven instantly because he is always, somehow, right. Heroes rise and empires fall on schedule; the little blue droid simply keeps rolling forward, remembering everything, telling no one.
