'Toy Story' (1995) and 'Toy Story 2' (1999)

From the fearsome to the timid. One of the most endearing supporting characters in the "Toy Story" movies is Rex, the insecure green plastic dinosaur toy voiced by Wallace Shawn. Rex is constantly terrified that his owner Andy will ... morereplace him with a bigger, scarier dinosaur. Rex just isn't the ferocious roaring type. "I don't like confrontations!" he laments in the first film. Still, Rex works up the courage to join the expedition to rescue Woody in the second movie.
