Harry Sabin created a very interesting guest character when he designed the wizard Catillus for the She-Ra season one episode "He Ain't Heavy". One of the best things about Catillus is that he did not look like the typical guest character. Without offending anyone Filmation often tried to keep their guest characters locked into a certain physique so that stock movements could be applied to the characters with little effort. She-Ra was notable for breaking away from stock designs as soon as the series started production. Catillus' physique is unlike any other character in the show. John Erwin's appearance as Prince Adam and He-Man in this episode meant that Catillus was voiced by one of the best Filmation voice actors when John was given his role!
