Mantis A Vingança Que Não Tarda (1994), the highly-watched TV movie on which this series was based, featured a predominately African-American cast and racism was a major issue in the story. Fox executives thought that the racial focus of the movie was "too grim and too realistic". Except for Carl Lumbly, the African-American actors from the movie were replaced in this series. Lumbly, Gina Torres, and Christopher M. Brown stated in interviews that they were very disappointed that the tone of the series was changed.
The M.A.N.T.I.S. writers offices on the Universal lot were demolished during the production of the series in order to make space for the "Jurassic Park" ride.
In the pilot, "M.A.N.T.I.S." stood for: Mechanically Augmented Neuro-transmitter Interception System. Otherwise known as the "exo-skeleton". But the network felt that the public would get confused by this, and would always be asking themselves, "What's that suit called again?" So the actual series producers, Danny Bilson and Paul De Meo (who had previously done "The Flash") had one of the supporting characters in the first episode of the actual series run, upon seeing the title character in the suit for the first time, say "Wow, you know? It kinda looks like a Mantis!" thus removing the need for an acronymic title. The only mention of the acronym in the TV series is in the episode The Eyes Beyond (1994), where a computer display shows what M.A.N.T.I.S. stands for. However, in this graphic, the word "Integrated" is used instead of "Interception".
Carl Lumbly is the only cast member to appear in both the pilot movie and series.
