The character of reporter Hector Ramirez would appear in various TV shows made by Sunbow. Besides appearing in Jem, he appeared in episodes of G.I. Joe (1985), InHumanoids (1986), and The Transformers (1984).
According to interviews with show creator Christy Marx, while all of the Holograms' first names were already chosen by Hasbro (the creator of the toy line), she gave them all last names that corresponded to scientists who were at the time working on holographic technology. Similarly, she named villain Eric Raymond after her own brother.
The show's title and main character were originally going to be named "M," but a single letter can't be copyrighted.
In one scene where people are watching several television screens, you can see a news report of an attack by the Inhumanoids (who were monsters from a show of the same name, InHumanoids (1986), also produced by Sunbow).
The Rockin' Roadster toy contained a real working FM radio.
