‘King of the Hill’ Season 15 Character Ages Explained For The Full Arlen Cast

‘King of the Hill’ has built its Hulu revival around a choice that once felt unlikely for an animated sitcom, letting its characters actually grow older. Rather than resetting its characters, the revival embraces the passage of time, with the Hills returning to a changed Arlen and reconnecting with old friends who have aged right alongside them.

The starting point for all of it was Bobby Hill, whose confirmed age set off a chain reaction of questions about everyone else in his orbit. From there, outlets and fans worked out how much time had passed for the rest of Rainey Street, and here is what has been confirmed for the full main cast.

Bobby Hill

Bobby was 13 years old for the entirety of the original thirteen season run, and he is now confirmed to be 21, a detail stated outright in the revival’s premiere episode. That jump from awkward middle schooler to working adult stands as the single biggest transformation in the entire revival.

In the season opener, Bobby is introduced as a chef and part owner of Robata Chane, a Japanese German fusion restaurant, a career choice that reflects his long standing interest in cooking. He skipped college to pursue that path and now lives in a small apartment with his old neighbor Joseph Gribble.

Hank Hill

Showrunner Saladin K. Patterson confirmed that Hank is mid to late fifties as of the start of the new season, while co-creator Greg Daniels noted the character was never given a firm age on the original show, though the team had privately worked with forty one as a reference point. That gap between Hank’s earlier unofficial age and his current one underscores how loosely the show’s internal timeline has always worked.

The premise finds Hank and Peggy returning to Arlen after years working a propane job in Saudi Arabia to build their retirement nest egg, reconnecting with longtime friends Dale, Boomhauer and Bill. Hank’s stubbornness has carried over intact, but the show now lets him react to a changed world as an older man rather than a fixed sitcom dad.

Peggy Hill

Peggy’s exact age was never stated on air during the original series, though she was written as roughly the same age as Hank at the time. For the revival, Kathy Najimy has confirmed the character was aged up by a full decade, and the actress admitted she was initially caught off guard by that shift before embracing it.

Now retired from substitute teaching, Peggy returns to Arlen with the free time to chase new projects, and Patterson has said the writers wanted to have fun with what those projects could be. She reunites with an adult Bobby and a hometown that has changed considerably since she and Hank left.

Connie Souphanousinphone

Connie is now 21 years old, much like Bobby, and she is now a student taking on demanding coursework at UT Dallas. Lauren Tom, who voices the character, has said Connie is now much more open and open minded than she was as a kid.

Tom told UPI in an interview that adjusting to Connie’s new age actually came easier than voicing her as a preteen, since the character in her twenties sits closer to Tom’s own voice. Connie is introduced this season navigating a relationship with Chane Wassanasong before eventually reconnecting with Bobby.

Dale Gribble

Dale was written as 42 years old during the original series run, and he has aged the same decade as Hank and Peggy, putting him solidly in his fifties for the revival. He remains an exterminator by trade and is still married to Nancy, still cheerfully unaware of who Joseph’s biological father is.

The most significant change to Dale’s life in the years off screen is that he ran for mayor of Arlen on an anti masking campaign and actually won, a victory that came at only nine percent of the vote due to a crowded field. Even his own friends and family were reportedly stunned by the result.

Bill Dauterive

Bill was written as 41 years old in the original series, and like Dale and Boomhauer, he has aged the same decade into his fifties for the revival. Stephen Root, who continues to voice him, has called the choice to let these characters visibly age genuinely rare for animation.

The years away were not kind to Bill, who became a shut in with a long beard during the pandemic and let his house and body go to pot. He is still something of a hermit when Hank and Peggy first return to Arlen, though their arrival is what eventually starts to pull him back out.

Boomhauer

Boomhauer has aged the same decade as the rest of the Rainey Street group, placing him solidly in his fifties alongside Hank, Dale and Bill. Of the alley regulars, he appears to be the most comfortably settled into retired life.

He occasionally picks up jobs through an app called ChoreChimp, work that eventually pulls Hank in as well after an on the job injury. The two also end up clashing over Boomhauer’s attempt at coaching a youth soccer team, giving the pair some rare season long friction.

Nancy Gribble And John Redcorn

Nancy and John Redcorn were both established as adults roughly in step with Hank and Peggy’s generation during the original series, and both have aged the same decade as the rest of the Rainey Street cast for the revival. That continuity keeps their long running dynamic within Arlen’s older resident group intact.

Jonathan Joss returned to voice John Redcorn for the new season before his death in June 2025, with Patterson confirming the actor was able to record his episodes before passing. Having these longtime supporting characters age alongside the leads keeps Arlen feeling like one continuous, lived in community rather than a rebooted set of strangers.

The show’s willingness to let its entire Arlen cast actually get older, rather than freezing them in place the way most long running animated series do, has become one of the clearer signs that this is not a simple retread of the original run. Which of these age reveals surprised you the most, Bobby finally growing up or Dale somehow winning an election in his fifties.
