Fridge Brilliance: Why are the Megaranger suits the same safe color and a slight tweak of vizor shape? It's cause this season heavily involves video games, and in the mid-90s when this came out, Palette Swaps were common.
Ho Yay: In episode 6, Miku tells a boy that wants to date her that she likes another person. When the other Megarangers asked who that is, Miku grabs Chisato's hand and goes to take her for tea. It's a minor example as, later on the series, it's revealed that she likes Shun, as well as Chisato being shocked by Miku's choice and actions.
The Scrappy: That girl from #39, who finds out Megared's identity and blackmails him to do everything for her. Annoying brat.
Tough Act to Follow: Not the series itself, but rather, one of the specific arcs, the Neziranger arc. The arc executed the Psycho Rangers concept so well that Toei hasn't tried anything else like it since then - although evil rangers have been used since, a team in the same vein as the Nezirangers hasn't been made.
Win Back the Crowd: Thanks to Carranger, Toei has given another shot in saving Sentai from being cancelled and Megaranger did exactly just that.
