In the animated sitcom King of the Hill, Joss voiced the character of John Redcorn, a Native American "licensed New Age healer" from season two onwards.
The sitcom centres around the Hill family and is set in the fictional town of Arlen, in suburban Texas.
For the first four seasons, Redcorn is having an affair with Hank Hill's neighbour, Nancy Gribble. Nancy's husband Dale is oblivious.
While a flawed character, Redcorn is known for his kindness and calm persona, and for championing his Native American heritage.
In season four, during perhaps his most notable storyline, Redcorn reveals an ongoing battle between his tribe and the Bureau of Indian Affairs, saying he hoped to regain Native American land from the government.
Considering Redcorn a "true friend", Dale decides to help him with the lawsuit filed against the government, by introducing him to the Freedom of Information Act.
Redcorn then permanently ends his14-year affair with Nancy, out of respect for Dale. The affair is not revealed to Dale and he happily heads home with Nancy.
