He is voiced by Pamela Hayden. In the Japanese dub from the series, he is voiced by Mari Mashiba.
Rod often prays, first thing in the morning and last thing before going to bed. He prays for God to watch over him and his little brother, Todd. He prays for the success of his father's business. He also prays for the success of all Christians, but due to his upbringing does not respect people of other (or no) faiths. Aside from praying, Rod enjoys playing with Todd and eating lots of "Nachos, Flanders-Style" (cucumbers with cottage cheese). His one regret is that he can't pray at school.
Rod's favorite songs are "Bringing in The Sheaves" (followed closely by "Noah And The Arky-Arky") and "I've Got the Joy, Joy, Joy, Joy Down In My Heart".
Rod has type 1 diabetes and has described being quiet and during trips as one of his favorite hobbies (including clapping during songs).
