R2-D2, pronounced Artoo-Detoo and often referred to as R2 (Artoo), was an R2-series astromech droid. A smart, spunky droid who would serve a multitude of masters over his lifetime, R2-D2 was never given a full memory wipe nor did he ever receive new programming, with these factors resulting in an adventurous and independent attitude. Often finding himself in pivotal moments in galactic history, his bravery and ingenuity saved the galaxy on numerous occasions.
