Orson Pig is the main protagonist of U.S. Acres. He is considered the "straight man" of the cast, since his personality is more neutral. He communicates with Wade more often than all other characters (in the TV series version), mostly complaining to Wade for having so many fears. Orson has the responsibility of treating Booker and Sheldon like they are his children since he looked after them. In the comic strip, Booker and Sheldon's mother abandoned her own children out of sheer laziness to take a vacation and never returned.
