Cartoon Network spokesperson Jean Woo told io9 that the character of Jared Shapiro was created by writer Haley Mancini and co-executive producer Bob Boyle, and Mancini was the principal story writer for the character. The network didn’t clarify why Goldman was brought on to voice the character, but it’s not uncommon for animated shows to include their writers or artists in the show—like Pendleton Ward, who voices Lumpy Space Princess on his show Adventure Time. Plus, former Powerpuff Girls storyboard artist Grace Kraft wrote on a Twitter thread that the artists modeled Jared after Goldman because he fit the character, and figured it’d be fun if he voiced him too.
