R2-D2 is a robot character in the Star Wars universe created by George Lucas. An astromech droid (referred to in the novel as a 'thermocapsulary dehousing assister'), R2-D2 is a major character in all Star Wars films, and is also the first character to appear in the franchise. Along with his protocol droid companion C-3PO, he joins or supports Anakin Skywalker, Luke Skywalker, Princess Leia, Padmé Amidala, and Obi-Wan Kenobi in various points in the saga. English Actor Kenny Baker has played R2-D2 in all six original Star Wars films and reprises the role in Star Wars: The Force Awakens, the first installment of the sequel trilogy, making him one of just two characters/actors along with C-3PO (portrayed by Anthony Daniels) to appear in all seven films.
