King of the Hill is an American animated sitcom series created by Mike Judge and Greg Daniels.
Hank Rutherford Hill is a tall, strict, and serious father and husband. He frequently boasts his selling of "propane and propane accessories" and is a proud worker for Strickland Propane. Although Hank is well-meaning, he can be somewhat annoyingly compulsive about little things and aggressive to others, for example, in "Hank's Dirty Laundry" he goes to court to get out of paying $40 for a pornography film he didn't rent. The assistant manager is the usual-protagonist of the series, and in a lot of episodes, he must fix everything after his friends mess up something important of his. He resembles the character Tom Anderson from Beavis and Butt-head.
Margaret Platter "Peggy" Hill is a well-meaning but arrogant and conceited mother and wife. She is seen often to think she is very smart and she tends to be over-protective of Bobby and sometimes, Luanne. On top of this, she is a substitute Spanish teacher at Tom Landry Middle School, but will gladly jump on any opportunity to substitute, like in "Square Peg" where she becomes the sex ed teacher. She is also a winner of the Tom Landry Middle School Substitute Teacher Award three years in a row, and has been or is a restauranter, ("High Anxiety") an avid boggle fan ("Peggy the Boggle Champ"-present), a newspaper columnist ("Bystand Me"-"Glen Peggy Glen Ross") and a real estate agent ("Glen Peggy Glen Ross"-present).
Robert Jeffery "Bobby" Hill is Hank and Peggy's overweight son who has an ambition to be a prop comic when he's older, much to Hank's dismay. Bobby has awkward moments with Hank, and the two get along in an on and off fashion, sometimes Hank is proud of his son, like in "Suite Smell of Excess" where Bobby gets a liking in football, but sometimes he is bitterly shamed of him, like in "Bobby Goes Nuts" where Bobby fends off bullies by kicking them in the groin. Despite all this, he is loyal to his father and only wants to please him.

He is a skinny, smoking exterminator, who do to his health is told he could die before he is 50, in "The Exterminator". Most of the time, it is Dale in fact who causes most of Hank's trouble. Dale owns many possessions he seems to find important and loves baskets, as we find out in "Dreamweaver".

He usually only likes woman for one-night stands but he falls in love in "Dang ol' Love" with a woman who in coincidence, only wanted a one-night stand.
