===Character development===
Despite being credited as a "special guest star" in every episode, Smith became the pivotal character of the series. The show's writers expected Smith to be a temporary villain who would only appear in early episodes. Harris, on the other hand, hoped to stay longer on the show, but found his character to be boring, and feared it would also quickly bore viewers. Harris "began rewriting his lines and redefining his character", by playing Smith in an attention-getting, flamboyant style, and ad-libbing his scenes with ripe, colorful dialogue. By the end of the first season, the character was established as a self-serving coward whose moral haughtiness and contrasting deceitfulness, along with his alliterative insults largely aimed at the Robot, were staple elements of each episode.{{r|pioneersoftv}}
