R2D2

Astromech Droid from Star Wars

Small, cute, but with an electric shock gun. Oh, and he can fly. Apparently. Since this in "Hype of the Clones" he probably hums the X-wing attack theme to himself as he does so. Generally teamed with C3PO. Speaks in bleeps like a mis-programmed ringtone that only Threepio can translate.
