There’s no “typical” episode of Ultra Q. There are typical episode types, such as the straightforward giant monster stories like “Terror of the Sweet Honey” and “Tokyo Ice Age”; horror episodes like “Devil Child” and “Baron Spider”; the fairy tales of “Grow Up! Little Turtle” and “Kanegon’s Cocoon”; and Twilight Zone and Outer Limits-influenced episodes like “Open Up!” and “The ⅛ Project.” But if I had to pick one episode to represent Ultra Q at its most typically atypical, the episode that manages to pack everything in the writers’ room junk drawer into a half hour, this is it. The last episode produced of the original 28, it reveals the creative team at full power, making one of the crowning achievements of the show.
