In August 2017, Judge and Daniels were revealed to have talked with Fox executives about a potential revival.[20] In an interview with Rotten Tomatoes the following March, Judge said he would want the revived series to include aged characters, such as an older Bobby.[21] In March 2020, Daniels revealed that Judge and he had an idea for the reboot. Daniels stated, "We do have a plan for it and it's pretty funny. So maybe one day."[22] In March 2021, writer Brent Forrester stated that a reboot was currently underway, stating in a tweet, "I am sure Greg Daniels and Mike Judge will murder me for sharing this but... HELL YES. They are in hot negotiations to bring back King of the Hill." The reboot will possibly feature "aged-up characters".[23]

Bill Dauterive (Stephen Root) lives across from the Hills. Known as the "Billdozer" in his high-school football glory days, Bill is now overweight, bald, and clinically depressed, still struggling to get over his divorce with his ex-wife Lenore. He is a sergeant and barber in the Army. He idolizes Hank and pines for Peggy, often trying to insert himself in the family. His intense loneliness makes him gullible and desperate for attention.

King of the Hill was met with universal acclaim and has since garnered a strong cult following. It was named by Time in its 2007 list of "The 100 Greatest TV Shows of All Time".[1] The series has won two Emmy Awards and has been nominated for seven. Its celebrity guest stars include Texas Governor Ann Richards, Chuck Mangione, Tom Petty, Alan Rickman, Michael Keaton, Johnny Depp, and numerous country music artists.

Hank and Peggy's only child is twelve year old Bobby Hill (Pamela Adlon), a student at Tom Landry Middle School. Much to the chagrin of his football-loving father, Bobby has little interest in athletics and instead aspires to become a "prop comic."

Dale Gribble (Johnny Hardwick; later Huss) is the Hills' chain-smoking, balding, conspiracy-theorist, next-door neighbor. He is married to Nancy Hicks-Gribble (Gardner), a weather reporter known for her good looks and charm. Dale is unaware that their only child, Joseph (Murphy, later Breckin Meyer, and later Tai Leclaire), is not his biological son, and is instead the result of Nancy's 14-year-long affair with John Redcorn (Victor Aaron; later Jonathan Joss), a Native American healer who has given her therapeutic massages for her "headaches" for years. Despite his inclination for conspiracy theories, Dale seems to be the only one in town unaware of the affair. His neighbors decide to keep Nancy's secret to preserve Dale and Joseph's loving relationship.

Judge and Daniels' reduced involvement with the show resulted in the series' format turning more episodic and formulaic.[7] Beginning in season seven, John Altschuler and Dave Krinsky, who had worked on the series since season two, took it over completely, tending to emphasize Judge's concept that the series was built around sociopolitical humor rather than character-driven humor.[7] Although Fox insisted that the series lack character development or story arcs (a demand made of the network's other animated series, so that they can be shown out of order in syndication),[7] Judge and Daniels had managed to develop minor arcs and story elements throughout the early years of the series, such as Luanne's becoming more independent and educated after Buckley's death, and the aging of characters being acknowledged (a rare narrative occurrence for an animated series).[7]

Bless the Harts, an animated series created for Fox, loosely shares a universe with King of the Hill, and features the Mega-Lo-Mart in the show. Story editors Christy Stratton and Emily Spivey for King of the Hill are involved in the show, although Judge is not.[10] It premiered on September 29, 2019, and ended on June 20, 2021, due to Fox canceling the series after two seasons.

King of the Hill is set in the fictional small town of Arlen, Texas.[4] The show centers on the Hill family, headed by the ever-responsible, hard-working, honest, but emotionally stunted propane salesman Hank Hill (Mike Judge). The punning title refers to Hank as the head of the family, as well as metaphorically to the children's game king of the hill. He often finds his traditional conservative values challenged by the changing world around him, though his common decency usually sees him through. Hank typically serves as the de facto leader for his friends and family.
