His other voice work includes the aforementioned Nightmare, and episodes of Jackie Chan Adventures and Justice League Unlimited (where he played Steven Mandragora).

On stage, Shadix was set to begin rehearsals for a Birmingham production of Alan Bennett's History Boys.

[6][7] Shadix was known to be a long-time fan of Joan Baez, dating back to his childhood, when he had to hide her records from his family who disapproved of the folk singer.

[8] In 2007, after spending 30 years in Los Angeles, Shadix retired to his native Bessemer, Alabama, where he purchased a Queen Anne-style, Victorian-era home.

According to his sister, Susan Gagne, he fell and hit his head in the kitchen at his condominium in Birmingham, Alabama, and died of blunt trauma.
