* BadassDecay: Eiji.
%% * BaseBreakingCharacter: Natsuki.
* BizarroEpisode: The aforementioned Task 39, coupled with {{Clip Show}}s of past episodes (first as they try to figure out which villain sent them the Prometheus Stone, then when its bomb is accidentally activated and everyone decides to stay together when it goes off). As it turns out, it was [[spoiler: Makino-sensei who gave them the Stone as a form of training, and they stopped the bomb in the nick of time by smothering the Stone in Aegean salt]]. That is, no henshin, no mecha fights, and [[ArsonMurderAndJaywalking Eiji and Masumi dancing hula]] among other things.
* BrokenBase: The suits. Are they the most awesome thing ever, or way too cluttered and ugly?
* CostumePorn: The suits are among the most high-tech and flashy in Sentai's 40-year run.
* CrowningMusicOfAwesome: The [[http://www.youtube.com/watch?v=KRR37r3VBzc rollcall theme]].
** "Boukenger! Go on Fighting!".
** Just have a go at ''[[http://www.esnips.com/doc/9e2f55a9-939d-4a68-aa6b-cebc2763c917/Start-Up!-~Kizuna Start Up! ~Kizuna]]'' and decide yourself. Though it was rarely used, sadly.
** Daibouken's theme, sung by the king of sentai robo themes, Takayuki Miyauchi.
* EarWorm: [[http://www.youtube.com/watch?v=SXBZEiT0CWo The opening theme]].
* FamilyUnfriendlyAesop: For Eiji: He's mixed-race (Human/Ashu), but that's okay, as long as he actively fights his racially undesirable side! This Aesop is especially strange since it was shown that his mother was kind-hearted which means AlwaysChaoticEvil should be averted, but alas...
** On the other hand, he has justified reason for so as his racially undesirable side is that of a destruction-loving literal monster. It could count as a FantasticAesop, because you can not be a HalfHumanHybrid in real life.
* FanNickname: [[spoiler:[[Manga/InuYasha Eijiyasha]], for the particularly familiar fashion in which his half-Ashu form manifests itself. And Ryuuwon's [[ButNotTooForeign obviously mixed-parentage]] human form earned him the nickname Enrique (last name Vallerte in the GagDub, referencing Carlos of ''Series/PowerRangersTurbo'' and ''[[Series/PowerRangersInSpace In Space]]''.)]]
** And Gajah himself, thanks to [[NiceHat his distinctive headgear]] = Pope Gajah, Chief Pope Hat and other variations.
* FridgeBrilliance: Natsuki/Bouken Yellow being a Lemurian Princess would look normal, unless you realize that back then in ''Series/DaiSentaiGoggleFive'', Lemuria is the civilization symbolized by Goggle ''Yellow''.
** In Task 22, several members of the team (Masumi, Natsuki, and Satoru) are transformed into different animals. Masumi is... A German Shepherd. However, this actually makes a lot of sense; Shepherds are favoured as police and army dogs, and are generally considered dangerous and aggressive. In reality, however, they are actually quite intelligent, friendly, and loyal--quite bit like Masumi himself. He comes across as the mean 'bad boy' of the group, but actually cares quite a lot about the team, and is much nicer than he originally gives himself out to be.
* HilariousInHindsight: Unless their numbers are being multiplied by special effects, you only seem to see a maximum of three Jaryuu on the screen at once, much like ''Series/LandOfTheLost,'' where you only saw three Sleestacks on camera at once because that's how many costumes they could afford.
** This ended up happening again in [[Series/KaizokuSentaiGokaiger the next anniversary series]] with the Sugormin, except in this case, it was because Toei only made 3 costumes as opposed to just not being able to afford more.
* {{Irony}}: Despite being one of the most loved Sentai series, it's American counterpart ''Series/PowerRangersOperationOverdrive'' is considered by some people to be the ''worst season in the entire franchise'', or at least one of the worst.
* [[HoYay Les Yay]]: The sequence where Natsumi imagined she was Cinderella and Sakura was Prince Charming.
* MagnificentBastard: The Questers. When you can not only manipulate the three main evil factions to provide the materials for the ultimate lifeform, but also unleash a long-lost cousin to keep the Boukengers further occupied, you're pretty magnificent in your bastardry.
* MemeticMutation: Let's just say Masumi is better remembered by his crooked teeth than by his actions.
* TheScrappy: That annoying kid from Task 5.
** And Natsuki at times.
* TearJerker: Episode 25.
* TheyWastedAPerfectlyGoodPlot: A couple episodes imply that the SGS doesn't fully trust the Boukengers and may be hiding things from them. This leads to... absolutely nothing.
* WhatAnIdiot: Gaja decides to revive the Ashu as the Questers, and he didn't even come up with a plan to keep them from turning on him.
