One Eyed Betty is a minor antagonist in the 2010 Oscar winning Disney/Pixar movie Toy Story 3. She is a western outlaw played by Mrs. Potato Head and is the wife of One-Eyed Bart, played by Mr. Potato Head.
When Sheriff Woody tells One-Eyed Bart to have a day with justice after Bart robs the train, One-Eyed Betty arrives to help Bart as she drives Woody backwards across the train tops until he ends up on a caboose. She then knocks Woody off the train in the face with her purse, but Woody catches up with the train by riding Bullseye with Jessie. After Bart blows up a railroad bridge, he and Betty escape with their stolen loot in a corvette that the Aliens are driving. However, the corvette is later sliced in half by Buzz Lightyear's laser. Bart tries to protect his wife and the Aliens with their "Attack Dog with a Built-In Force Field" (Slinky's role), then they are rescued by Evil Dr. Porkchop (Hamm's character) from having their force field destroyed by Woody's "Dinosaur Who Eats Force Field Dogs" (Rex's role) by being warped back into Dr. Porkchop's spaceship.
