Rocky Gibraltar

Rocky Gibraltar is a figure of a heavy-weight wrestler, probably based on the collectible Wrestling Superstars figures made by Hasbro. He is the strongest toy in Andy's room. He doesn't talk in the films, but in the Toy Story Animated StoryBook game he is shown to talk in third-person.

Toy Story
In the first Toy Story he's seen sitting in front of the door of Andy's room right before all his birthday guests burst in, which has him slammed against the wall after they leave. He was also lifting weights with Buzz and the other toys during the song "Strange Things". Later in the film when Woody tries to use RC to help Buzz, Rocky spins him over his head and throws him off the moving van, but then when the toys find out what Woody was really trying to do Bo Peep has Rocky lower the ramp to let them back on.

Toy Story 2
In Toy Story 2, Rocky tries to hold back the door with the help of the Green Army Men to keep Buster out of the room, but once again the door is too much for him.

Trivia

 * In the moving van scene on the Toy Story Animated StoryBook game, Rocky will keep going to the back of the moving van when clicked on and pull out random objects to throw at Woody and Buzz because he thinks he's helping them (most of which being things that are completely useless or absurd, such as a lifesaver or a model of the Eiffel Tower).
 * Rocky's name and the logo on his championship belt are references to the Rock of Gibraltar.
