After leaving "Kotter" in 1977 and amicably ending his partnership with Palumbo, Evanier wrote for and eventually ran the Hanna-Barbera comic book division. He also wrote a number of variety shows and specials, and he began writing for animated cartoon shows, including "Scooby-Doo and Scrappy-Doo", "The Plastic Man Comedy/Adventure Show", "Thundarr the Barbarian", "The ABC Weekend Special", "Yogi Bear's All Star Comedy Christmas Caper", "Richie Rich", "The Wuzzles", and "Dungeons & Dragons". He is most noted in animation for his work on "Garfield and Friends", a seven-season series for which Evanier wrote or co-wrote nearly every episode and acted as voice recording director. Since 2008, Evanier has been the co-writer and voice director of "The Garfield Show", which won a Daytime Emmy Award for Outstanding Performer in an Animated Program for June Foray.
