Evil Dr. Porkchop, also known as simply Dr. Porkchop or Mr. Evil Dr. Porkchop, is Hamm's wicked double in the 1999 and 2010 Disney/Pixar movies Toy Story 2 and Toy Story 3.
He is an outlaw played by Andy Davis' piggy bank Hamm wearing Mr. Potato Head's bowler hat. Like Hamm himself, he is played by Pixar's good luck charm John Ratzenberger who also played the Underminer man.
Toy Story 2
He first appears in Toy Story 2 when Andy sets up a stage before leaving for Cowboy Camp. He kidnapped Bo Peep and threatened to have her eaten alive by a shark or monkeys but Woody and Buzz Lightyear rescued her, with RC's help.
Toy Story 3
Porkchop later returns in Toy Story 3 at the beginning in Andy's realistic imagination, controlling a pig-shaped spaceship. He rescues One-Eyed Bart, One-Eyed Betty, the Force Field Dog and the Alien henchies (played by Mr. and Mrs. Potato Head, Slinky Dog and The Aliens) right when the Dog Eating Dinosaur (played by Rex) is about to eat them. Porkchop thens orders his monkeys to capture Woody, Buzz and Jessie. Later at the end of the movie, when Andy hands Hamm over to Bonnie Anderson, he calls him Dr. Porkchop and they played with him like that.
He appears in the first and lasts storymode levels of Wii, Xbox 360, PC and Playstation 3 versions of the Toy Story 3 video game as well, but also with a black patch over his right eye. He is also the hidden true main antagonist of the Xbox 360 and Playstation 3 versions' toy box mode.
