It seems more of a Japanese theatrics thing based on my accumulated consumption of Japanese media such as kabuki and the jidaigeki and chanbara genre.
Heck, the concept of a role call in toku has residues of kabuki theater if you look at it.

Can't speak for Hurricaneger since I haven't seen anything except the first ep and the 10 years after and my memory of Bouken is also rather blurry, but here's some for the rest:

Magiranger: If you want some more action-packed stuff that represents the team dynamic, I would recommend Stage 11 and 12 as well as 23 and 24 (they're both two-parters and some of my favorite). For just a single episode, I'd say Stage 13 gives you a good image of what the show is all about.

Go-Onger: I'd go with GP 15 (and then maybe 16). It starts with one of my favorite gags in the show but also has some more serious elements to it, so it's basically a good representation of the directions the show can go in.

Shinkenger: Act 8 is a good one for just checking it out and seeing how the team works on a mission. It's a pretty cool one when it comes to the team's way of planning.
To get a feel of the team's interaction, Act 18 and Act 22 are pretty interesting.

Goseiger: Epic 11 gives you a nice feel of the show and characters and the overall energy that most episodes have. It has both a positive vibe as well as some dramatic background and a feeling of urgency. Epic 16 is one of the best episodes to get the overall message of the show and the potential of especially GoseiRed.

Ninninger: Shinobi 7 is cool to check out if you want to have a good contrast between Ninninger and the older teams. I think the conclusion is in Shinobi 8, which is also perfectly fine to check out as a standalone ep that illustrates the family ties of Akaninger and Shironinger. Shibobi 13 is a very good one for team dynamic as it highlights them working together, while Shinobi 16 broadens the dynamic to the whole Igasaki family.


It actually IS a samurai thing. Samurai used to introduce themselves and who they worked for (which is probably what the Shinkenger's "The same" stands for), which got them slaughtered by the mongols in the past. The only thing that saved Japan from mongolian occupation was that the invaders were killed in their boats when they sent more troops to the country, as a strong typhoon drowned and smashed them. That's also where the term "Kamikaze", "Divine Wind", originates from. It was originally the divine power that protected the Japanese from Mongolian Occupation back in the day. (Culture class in Japan ftw.)

I know this was not on the list but Gingaman episode 1 I think was a great setup episode looking back now.
