* ActorAllusion: The final episode features cameos by Kazuo Niibori and Naoki Ofuji, the suit actors for Red Hawk and Black Condor, as [[spoiler:the priest who conducts Ryu's wedding with Kaori and the mugger who stabs Gai respectively]].
** It's also FridgeBrilliance.
* TheDanza: Kaori's prehistoric counterpart in episode 26 is called Rika, just like the actress playing her.
* HeyItsThatGuy: Several.
** Tranza is famed mid-80s Sentai villain actor [[Series/ChoushinseiFlashmanYutaka]] [[Series/ChoujuuSentaiLiveman Hirose]].
** The Dimensians from the Bird Garuda intro arc are 2/3 this - [[Series/ChoushinseiFlashman Rei]] and [[Series/HikariSentaiMaskman Kanna]] show up prior, while [[Series/KyoryuuSentaiZyuranger Dan]] shows up the next year - in the same color no less!
** Ryu's biologist friend from 38 is [[Series/DengekiSentaiChangeman a fellow Red warrior]].
** [[Series/KyoryuuSentaiZyuranger Neo J1 shares the same situation as Dan - and plus points for being Ryu's analog.]]
** [[Series/ChoujuuSentaiLiveman Jou]] shows up as one of the scientists developing the Fire Bazooka.
* NamesTheSame No, the Blue Swallow Hotel isn't named after Ako.
* PeripheryDemographic: J-drama magazines of the time had coverage of Jetman, something not seen before or since from a Sentai.
* RomanceOnTheSet: Kotaro Tanaka and Rika Ishida ended up marrying in real life after the show aired.
* WhatCouldHaveBeen: A [[http://henshingrid.blogspot.com/2010/11/mecha-early-designs-and-scrapped-ideas.html Super Sentai art book]] showed that they were gonna have a giant, heavily armed fortress robot, like in ''Turboranger'' and ''Fiveman'', but didn't go through with it (from the sketches, it would've been a retooled version of the Turborangers' Turbobuilder).
** Like ''Sun Vulcan'', ''Bioman'' and ''Turboranger'', this series was originally going to be the first ''Franchise/PowerRangers'' series. However, Saban passed on this series in favor of [[Series/KyoryuSentaiZyuranger the next one]].
** Due to how much ''Fiveman'' flopped (as noted on the trivia page [[Series/ChikyuuSentaiFiveman for that series]]), Toei originally had intended for this to be the last Sentai series. Fortunately, this series ended up saving the franchise.
