R2-D2

R2-D2 was the droid that never died, capable of producing any needed device out of his ass [read "droid rear porthole"]. He served nearly everyone in the galaxy, and was essentially responsible for Star Wars even existing, because if he hadn't fixed that hyperdrive, none of us would be here and all that Clone Wars shit and Galactic Empire stuff might never had happened either. Luke and Leia would have never been born to save the galaxy either, because Padme Amidala Qui-Gon Jinn and Obi-Wan Kenobi would not have landed on Tatooine to find Anakin Skywalker, bet on a race, and free him from slavery. They would all have been dead. Then Palpatine would be wondering what the frack is he going to do now?
