Rex (voiced by Wallace Shawn) is one of the many toys in Andy's Room in Jaden's Adventures of Toy Story. Rex was worried he would ever get replaced, and therefore never be played with again. He was fascinated by Buzz Lightyear's features along with many other toys. When Woody and Buzz went missing, Rex was nervous, but soon they got back, and Rex wasn't nervous about being replaced again, after seeing how Andy was sad about losing them.
