Hermes is married to LaBarbara Conrad, with whom he has a son Dwight. LaBarbara was formerly married to Hermes' former Limbo rival Barbados Slim, and reunited with Barbados twice when Hermes was temporarily decapitated in Bender's Big Score. Hermes is also overweight, caused by over three decades of overeating including LaBarbara's goat curry, which has made his skin too spicy and acidic for consumption by others.
