"Ultra Q" can be described as a half-hour Toho kaiju series. Executive Producer Eiji Tsuburaya intended this series to be more like the American television series "The Twilight Zone" and "The Outer Limits", featuring a variety of strange and unusual stories. After a survey, the TBS network convinced Tsuburaya Productions to add more giant monsters, as children were intensely interested in them, since Godzilla (Gojira) and Gamera were all the rage at the time (the first "Kaiju Boom" took off after "Ultra Q" became an enormous hit). Much like "The X-Files", the series features continuing characters who investigate strange supernatural phenomena, including giant monsters, aliens, ghosts, and various other threats.
