Fatso's brashness and quick temper often led him into mishaps, as well as an occasional role in one of Casper's adventures Fusso and Lazo were sometimes called 'the Ghostly Duo' in his absence. The third ghost, Lazo, was the tallest, laziest and least intelligent. Fatso's 'second-in-command', Fusso, was portrayed as average in height and build and was characterized by exceptional fussiness and attention-to-detail. He was the Trio's leader, as the toughest and (marginally) smartest of the three. Similar to his later incarnation, Fatso was overweight and gluttonous (although, as ghosts were capable of eating in the early stories, this trait was not as odd as it later seemed). In Casper's earlier appearances in Harvey's animated cartoons and comic books, the Ghostly Trio were depicted differently, although they were brothers. These relatives did not appear to have special traits or serve any other purpose. Originally, Casper was featured on the show with ghost relatives who looked similar and liked to scare people.
