XR is a character in Buzz Lightyear Star Command. He is a robot who was a very good assistant to Buzz, until when XR was broken, Zurg stole the Uni-Mind, the Star Command Little Green Men 'fixed' him, and he turned out all smart, like the 'Brain' Gremlin from the horror film, Gremlins 2. At the end of the movie, XR became Buzz Lightyear's partner.
