R2-D2 (Earth-2356)

R2-D2, pronounced Artoo-Detoo, is an R2 series astromech droid manufactured by Industrial Automaton with masculine programming. A smart, spunky droid serving a multitude of masters over its lifetime, R2 never had a full memory wipe (apart from a partial mind-wipe by Cad Bane during the buildup to the senate hostage crisis) nor has he received new programming, with these factors resulting in an adventurous and independent attitude. Oftentimes finding himself in pivotal moments in galactic history, his bravery and ingenuity saved the galaxy time and time again.
