R2-D2 (Earth-2042)

"«Thank you for telling me all this. I know it can be hard to talk about, but war stories are important. I sometimes think it's my destiny—to see things, to be present, to witness the galaxy moving, evolving. It happens to me over and over again—but even so, I can't see everything. And so, I like hearing the stories. Recording them."

- R2-D2, to BB-8

R2-D2, pronounced Artoo-Detoo and often referred to as R2 (Artoo), 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 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.
