* AntiClimaxBoss: [[spoiler: The final villain destroyed by our heroes is just another [[MonsterOfTheWeek Brain Beast]].]]
* {{Anvilicious}}: Japanese universities tend to have high entrance standards compared to Western ones, and it's still not uncommon to find students struggling to get in. Knowing this makes the "getting a good score above all" thrust of the overly Elitist Volt hit a bit closer to home...
** SomeAnvilsNeedToBeDropped: Not that the lesson is a bad one.
** Also, life, youth, and your humanity are important and can't be spurned or destroyed. [[spoiler: Bias tries and ultimately fails to completely purge the four doctors of their humanity like he has done to himself, ruins others' lives for his goals, and is trying to create an artificial Fountain of Youth, meaning he abuses all three of these things.]]
* BigLippedAlligatorMoment: Moonwalking Colon.
* CrowningMusicOfAwesome: "Taiketsu! Zunojuu" ("Duel! Brain Beast") is the quintessential 80's Sentai "Duel" theme. Strings and brass for the win.
** The themes for the Bimotion Buster and Live Robo's Super Live Crash both have an assurance of victory about them. (In fact, if you've ever heard Bimotion Buster before, [[EarWorm you're humming it now]] - you're welcome.)
** The Mecha themes that start getting used after Live Boxer is introduced, and ''especially'' "Live Boxer's Song".
* EarWorm: ''Seishun, Bakuhatsu, FIRE!! Seishun, Sakuretsu, FIRE!! Chojuu Sentai! Liveman!''
* MagnificentBastard: Great Professor Bias, who [[spoiler:manipulated his students with Gash's help in order to initiate Mass Hypnosis and a Fountain of Youth. By the time this is revealed, he is cemented as The Unfettered, and even as his plans start breaking down, he's determined to continue, which ultimately leads to his death.]]
* MoralEventHorizon: Bias is cold and egotistically heartless for the entire series, but there's just no coming back after it's revealed he gave [[spoiler: Butchy ''memories of a happy life on Planet Chibuchi'', only to tell him he's a robot, and those were programmed.]]
** [[spoiler: Then his whole Fountain of Youth/Mass Hypnosis plan is revealed, along with the revelation that he crossed the Horizon a looooooooooong time ago. Taking your students' brains and leaving the failures to die? ''Twelve times?'']]
* NeverLiveItDown: Megumi only cries once or twice in the first few episodes, which somehow translates into her sobbing almost every episode.
** [[FridgeBrilliance She's the water-based Ranger, it's unavoidable...]]
*** She didn't cry once or twice overall, she ''does'' cry in some other episodes, but still not actually OnceAnEpisode.
** Junichi's MisterSeahorse moment almost always gets mentioned in any discussion of the series.
** So does Jou's unfortunate moment with that dinosaur.
* NightmareFuel: Dr. Oblar before turning full-on monster. That mouth... ''*shudder*''
** Kemp's transformations. [[MonsterOfTheWeek Kemp-zuno]] ''especially'' - imagine a [[Franchise/{{Alien}} Xenomorph]] with spikes.
*** NightmareRetardant: Except for Bijuu Kemp, who looks completely ridiculous for a Sentai monster.
* RewatchBonus: The final arc is so dark that fully appreciating it is hard to do with only one watch. Rewatching reveals certain tropes that can be missed due to the tragedy and evil that is prevalent throughout the arc.
* SuspiciouslySimilarSong: Doesn't the [[http://www.youtube.com/watch?v=yjz6ygF8PWM transformation theme]] sound a bit like the [[http://www.youtube.com/watch?v=64GyuozXtnQ opening music]] from ''Series/MagnumPI''?
* TearJerker: Quite a few, given the dark nature of the last quarter of the show.
** Arashi, after being 'dropped' by Bias, finally asks [[spoiler: Omura]] what 8+4 is, a problem that's vexed him since his introduction. Upon getting the answer he [[spoiler:notes that there's nothing left for him to do, remarks that it was a strange life, then straps on some dynamite and suicide tackles the as-yet unbeatable Brain Beast of the week.]]
** [[spoiler: ''All'' of the Volt members' final moments are like this. None of them are particularly easy to watch.]]
* WhatDoYouMeanItsForKids: Seriously, this show gets ''very'' dark towards the end.
