* TheStarscream: [[spoiler: Mason attempted a coup...only to learn Doctor Man was ready for it.]]

* NonIndicativeName: This series does not have a BioPunk theme. Instead it's focused on robots.

* MidSeasonUpgrade: Gear switches to stronger robot monsters and upgrade the big three, so the Biomen receive an extra-boost in Bio Particles[[note]]resulting in them and the Bio Robo reverting to a singular FinishingMove each[[/note]]. The three remaining Beastnoids are also rebuilt into stronger forms.

* ReplacementGoldfish: The Black Prince, a Mecha Clone replica of [[spoiler: Doctor Man's son, Shuichi]]. Subversion since he is actually alive.

* NatureVersusTechnology: Would ''seem'' to be the main theme of the show, since despite their activities being enabled by a pair of robots, the Biomen are living people, while their enemies are all robots or cyborgs who've abandoned their humanity in exchange for power.

-->''One! Two! Three! Four! Five! Choudenshi! Bioman!''

* ShoutOut: In Episode 40, Juo sings part of the theme to ''Series/TheBeverlyHillbillies''.

* GenderedOutfit: A relatively unique variation in ''Super Sentai''. Yellow Four and Pink Five's suits have color pattern designed to resemble a leotard, instead of having a skirt or MiniDressOfPower like the vast majority of female rangers. This also happened with the respective female duos from the [[Series/DengekiSentaiChangeman next]] [[Series/ChoushinseiFlashman two]] Sentai teams.
