- Professor Zugar was portrayed by Doug McClure.
Although Professor Zugar only made one actual appearance on the Superboy television series in the episode Hollywood, he was mentioned by name by both Superboy and Professor John Peterson in the episode Microboy when they were discussing an updated version of Zugar's Time Machine that Professor Peterson was tinkering with. It was this same updated Time Machine that Superboy used to transport Hector Hornsby back to the year 1903 to save his life in that episode.
