- The title's etymology is in conjunction with the names "Dyna" from Dyna Dragon and "Zenon" from "God Zenon", the two assist mecha from the original Gridman series.
- Many places in the city where Yomogi and co. lives, Fujiyokidai, bears some similarities with Tsutsudjidai from the previous series, which no surprise considering some shots in the show being recycled from ones in SSSS.Gridman.
