R2-D2

R2-D2, is an astromech droid and colleague of C-3PO in the fictional Star Wars universe, created not long before 32 BBY. R2-D2 was played by Kenny Baker in all six Star Wars films, with many scenes filmed using mechanical versions of the character. R2 is the only character (despite being a non-living droid) to appear in all six Star Wars films, without changes to appearance or speech, unlike his colleague C-3PO, Obi-Wan Kenobi, or Darth Vader. Along with his resourcefulness, R2 had many tool-tipped appendages that allowed him to be a great starship mechanic and computer interface specialist. A light droid, R2 would often enter dangerous situations without second thought.
