Miss Piggy is one of the central characters on The Muppet Show. She is a force of nature who developed from a one-joke running gag into a complex, three-dimensional character.Miss Piggy is a prima-donna pig who is absolutely convinced that she's destined for stardom, and nothing is going to stand in her way. Her public face is the soul of feminine charm, but she can instantly fly into a violent rage whenever she thinks she's insulted or thwarted. Kermit the Frog has learned this all too well; when she isn't smothering him in kisses, she's sending him flying through the air with a karate-chop.
