Star Wars Character: R2-D2

R2-D2 is one of the droids built by Anakin Skywalker. As a repair droid, he is very proficient at interfacing with and manipulating other computer systems. He plays a crucial role at several points in the original trilogy. He most famously carries a message from Princess Leia to Obi-Wan Kenobi. R2 also demonstrates a somewhat sarcastic sense of humor and seems to delight in taunting C-3PO.
