Produced in black and white by Tokyo Broadcasting System/Tsuburaya Productions, Ultra Q is actually the first of the long-running Ultra Series, and was broadcast on Tokyo Broadcasting System from January 2 to July 3, 1966 (the final episode was preempted until December 14, 1967), with a total of 28 episodes. This series was followed a week later by the more well-known Ultraman (Urutoraman, 1966), the second Ultra Series.
Unlike most of the franchise it would spawn, it did not have a size-changing Henshin Hero. Instead, it was more of a mystery-of-the-week format that gets it compared to The Outer Limits (even with an intro reminiscent of it!) with, of course, giant monsters being the culprit a lot more often than it was in those series.
Ultra Q provides examples of the following tropes:
- Casting Gag: Gomess and Pagos were made using the respective suits of Godzilla and Baragon. Likewise, they shared the same suit actor — Haruo Nakajima.
- Egg MacGuffin: Litra's egg in the first episode, as Litra is the only thing capable of killing the monster Gomess, so they try to hatch the egg in the hopes that Litra will take care of the rampaging monster for them.
- Gilligan Cut: In "The Gift From Space", the lead scientist asks the small airline operator to place the story's plot Macguffin somewhere safe. Without showing him putting it away or anyone casing the facility, in the next cut it shows a thief using a blowtorch on the payroll safe. Naturally, the thief mistakes the plot device for gold he can steal and danger ensues.
- Opening Narration: "For the next 30 minutes, your eyes will leave your body and enter inside this fantasy time..."
- Stock Footage: Parts of Sudar's island rampage in "Fury of the South Sea" are recycled from the giant octopus scene in King Kong vs. Godzilla.
- Theremin: The music and the theme had this and the musical saw.
- Too Dumb to Live: One episode, "Grow Up Little Turtle", features a child who, after being accidently kidnapped by thieves, takes one of their guns, looks down the barrel, and presses the trigger! The gun misfires, but it goes off when one of the thieves gets his hands on it again, showing it was perfectly functional.
