This story features the origin of Modulok, but because the series was produced to be broadcast in syndication it did not have a set broadcast order. Therefore Modulok appears in the earlier Happy Birthday Roboto (1985) when watched in production order.
Galen Nycroft's character model was designed by Lew Ott and Modulok's animation design, based on Mattel's toy prototype, by Fred Carrillo & Lew Ott.
