* SugarWiki/AwesomeMusic: [[http://www.youtube.com/watch?v=q84Vg1Nd4XE Revolution]], the Survive Form theme.
** And before we had that, we had [[http://www.youtube.com/watch?v=sYTATi8U_YI Hatenaki Inochi (Boundless Life)]].
* BadassDecay: When Tiger first shows up, he's serving up TheWorfEffect like nobody's business ([[CurbStompBattle even to Asakura]]), but as time goes on and his real character comes through, he proves incapable of winning any fight at all.
** [[FridgeBrilliance A side effect of his deteriorating sanity, perhaps?]]
* CompleteMonster: Takeshi Asakura/Kamen Rider Ouja practically ''exists'' to murder people and [[EvilIsCool look cool doing it]]. Not only does he rack up the highest body count amongst the Riders, who are pitted in a battle to the death where ThereCanBeOnlyOne, but he's also responsible for the murder of an innocent woman (who turns out to be [[TheSmurfettePrinciple Kamen Rider Femme's]] sister, thus making getting revenge her reason for entering into the Rider Battle). To top it all off, he kills his own estranged brother by feeding said brother to his [[{{Mons}} Contract Monster]], Venosnaker... after revealing that ''he'' was the one [[MoralEventHorizon who set the fire which burned down their home, killed their parents, and separated them during their childhood in the first place.]]
* CounterpartComparison: Gets a lot with ''Anime/PuellaMagiMadokaMagica'', see bellow
* DarkIsNotEvil: Ren could count. He is AntiHero close to JumpingOfTheSlipperySlope. But he keeps his word and compared to other riders´ selfish motives tries to save a person dear to him. Also, he saves Kido´s butt (and not only his) more than a few times.
* EnsembleDarkhorse: Asakura remains a popular villain in the Rider franchise.
* EpilepticTrees: Odin was the subject of a ''lot'' of them due to his importance in the plot, the lack of direct explanation as to who or what he was (until the final episode) and certain promotional scans (such as one with him holding all three Survive Cards in his Gold Visor).
* GameBreaker: Ryuki and Knight's Survive Forms.
** Also Odin himself, able to ''beat'' a Rider in Survive form. Possibly invoked, because Shiro is the one controlling him and only brings him in to eliminate those who oppose him.
* HilariousInHindsight: One hallmark of ''Franchise/KamenRider'' and all {{Toku}} in general is the BlindIdiotTranslation subtitles on bootleg Hongkong [=DVDs=], so much that some characters get ''new names''. Goro in particular keeps getting called 'Inagaki', presumably because he shares the pet name 'Goro-chan' with Inagaki Goro of the immensely popular boyband [=SMAP=]. Fast forward 6 years to 2009, and the real Inagaki Goro lands the role of (the non-canon) Film/KamenRiderG.
** In a similar vein, Ren gets called 'Len' or 'Lian' a lot in the early eps of the bootleg [=DVDs=]. ''Series/KamenRiderDragonKnight'' picked Len eventually.
** Also of note is how Asakura's name was completely and senselessly altered to "Miyako".
** Perhaps the funniest bad translation is when Zolda summons his giant side-held cannon. His visor calls out, "Shoot Vent!" The subtitle for that line? "Jet Plane Landing!" Well, the cannon's *sorta* jetplane shaped if you squint...
*** Even worse is that the Visors are already in English...
* HollywoodHomely: Asakura looks WAY too healthy and clean for somebody that's been homeless since childhood
* HoYay: Kitaoka and Gorou. Especially in [[http://www.virtual-rotation.com/chirlind/others/sentai/3kamenry.html#dear their song, "Dear Friend"]], found on the soundtrack.
** [[spoiler:Shinji and Ren, particularly in the finale.]]
** Shinji and Gorou. "Gorou-chan, YOU'RE ALIVE!"
* LoveToHate: Asakura.
* MagnificentBastard: Kitaoka.
* MemeticMutation: Scissors' status as a ButtMonkey in the fandom, and comparisons to ''Anime/PuellaMagiMadokaMagica''.
* MoralEventHorizon: Sudoh firmly cements his villainy after taking advantage of Shinji's trust and getting information on Ren, he sicks Volcancer on Ren. Later he revealed to have crossed it before he ever appeared given that he routinely sicked Volcancer on anybody he didn't like.
** Jun already showed himself to a bastard, but he managed to one up himself when he planned to use ORE journal to set up a nation wide version of his deranged game that drove people to murder each other.
** Asakura manages to cram in a lot even for his prominence in the series:
*** As a child, [[SelfMadeOrphan he set fire to his own house and killed his parents]] in attempt to kill his little brother because [[EvilIsPetty he found him annoying]].
*** He committed a murder off-screen because the person in question annoyed him.
*** Lies about having tried to save his little brother and pretends to care about him so he can lure him out and kill him.
** Toujo crosses it when he kills Kagawa, believing that sacrifices those closest to him made a hero, and then crosses it again when he tries to kill Sano, after Sano had taken him and been so kind to him.
* {{Narm}}: Verde's Final Vent is one of the nastiest: with his chameleon monster's tongue acting as a bungee cord, he drops in on his opponent, grabbing him upside down, then bungees back up, flipping around twice before SMASHING his opponent head first into the concrete. Then the dust clears and we see the victim's legs ''still sticking into the air'' for a bit before toppling over. ...Yeah.
** Sometimes the result of SpecialEffectsFailure - watch in ep 39 as Ren is dramatically HANDED his {{BFS}} weapon from offscreen.
** When the maggot monsters are about to molt and evolve into more powerful creatures, the first thing they do is... jerk around like they're in ''Music/MichaelJackson's'' 'Thriller'.
* NightmareFuel: Sudoh's death where he gets eaten alive. ''Onscreen''.
* ParanoiaFuel: Behind every reflective surface (Mirrors, windows, any body of water, YOUR FRICKING COMPUTER SCREEN) is a monster...wait, I mean an ''army'' of monsters that is just waiting to [[ImAHumanitarian have you for dinner.]] They will pull you through the portal into the Mirror World, and kill you, leaving no trace behind and making it impossible for anyone to figure out how you were killed. If by some fluke you avoid the initial attack, they will not just try for someone else. They will keep hunting YOU down specifically until they get you. Also, the Mirror World is very hostile to those not native to it, and if you are there for too long, you will dissolve and die anyway (if you haven't already been eaten). Pleasant Dreams.
* UnpopularPopularCharacter: Asakura is an EnsembleDarkhorse, but how evil he is means most everybody in the show hates.
* TheWoobie: Yui. Let's count the ways, shall we? She and her brother spend their early childhood locked up in their home by their own parents, with nothing but drawing and a not-so-imaginary world to comfort them. Then, she suddenly dies at age seven, and is replaced by her Mirror World self in her brother's DealWithTheDevil. Following their parents' deaths, she and Shirou are forcibly separated. Twelve years later she finds out that she's not even real, she's only living on borrowed time and will disappear forever once she turns twenty, ''and'' that her brother is perfectly willing to manipulate twelve people - two of which are her closest friends - into killing each other in his mad scheme to save her. ''And'' that her drawings with her brother are what became the Mirror Monsters that are snatching people away and devouring them in seconds. Jesus.
** Oh, [[FromBadtoWorse it gets better]]. She gets to find all this out by ''being targeted for death'' by those who've worked it out, snatched by monsters, and finding herself starting to disintegrate at times. And it can all only be settled [[spoiler: by ''convincing her brother to let her death stick.'' The final scenes make it clear that to the world, Yui died long ago and ''stayed'' that way. (Her grandmother is all alone in the tea-house, and there's a picture of Shiro and Yui as kids.)]]
