* AwesomeMusic: [[http://www.youtube.com/watch?v=GoaMp3Q51Fo Kakusei]], sung by Ricky of Rider Chips.
** Speaking of which, there's also the [[http://www.youtube.com/watch?v=NwsrQOitTI4 Rider Chips version of the song]].
* CompleteMonster:
** Hiroshi Tennoji, the series' true BigBad, absolutely reeks of [[ItsAllAboutMe obsession for self-preservation]] [[TakeOverTheWorld and world domination by any means necessary]]. As the head of [=BOARD=], he creates the Battle Fight by releasing the Undead and manipulating his contracted Kamen Riders to take them out. As the battle progressed, he invented the Trials and the Titan Undead, all so he could buy himself time to create Kerberos, an artificial Undead with DNA from all 53 Undead that could surpass the Black Joker itself. Tennoji's invention kills the entire [=BOARD=] staff upon being born from the Stone of Sealing before he seals the artificial Undead to create a new Change Card. He uses the card to transform into Kerberos II before revealing his dream: [[TheCaligula to create a new world order with himself as its ruler.]] It takes all four Riders ([[SuperMode with Blade in his King Form and Garren in his Jack form]]) to stop Tennoji once and for all.
** Isaka, aka the Peacock Undead, exemplifies how low [[ManipulativeBastard manipulative bastards]] can go. As the first Category Jack Undead, he designed Rider System 3, a belt that allows the user to transform into Kamen Rider Leangle. Unfortunately, that same belt requires using an improperly sealed Ace card that contains the Spider Undead, meaning that its user would be mentally enslaved by the Undead (as later seen with Mutsuki). After designing the corrupted Rider System, he brainwashed many people that he was going to use as expendable slaves to create his "Ultimate Rider". When this plan failed, Isaka turns his attention to Sakuya Tachibana and attempts to retrieve him as a prototype user. Isaka knows about Tachibana's subconscious fear and takes advantage of it to [[CurbStompBattle curbstomp]] him. Isaka tricks his defeated opponent to getting addicted to [[FantasticDrug Schuld Ketsner seaweed]], lying that the aggression-inducing plant would eliminate fear. [[spoiler: When [[LoveInterest Sayoko]] notices her lover's addiction, Isaka smugly kills her for attempting to clean up her lover.]] Upon learning about [[spoiler:Sayoko's]] death, Tachibana loses his subconscious fear and eventually gives the bastard exactly what he deserves.
* CreatorsPet: Mutsuki Kamijo. He's despised by the audience yet the staff likes him.
* FountainOfMemes: In its native Japan; other than the Ondulish "language" this series Riders (especially Garren, for some reason) tend to cross over in other series fan art.
* FunnyAneurysmMoment: The Joker Undead defies whatever connotations its name implies, by being quite possibly the scariest monster in the show, despite being armed with just a knife. [[Film/TheDarkKnight Heath Ledger would do the same thing some years later]].
* GameBreaker: King Form.
* HilariousInHindsight: This series is filled with things that would be awesome {{Mythology Gag}}s if this series had aired about ten years later. A wind-powered Rider whose Rider Kick lifts its Rider in a cyclone, and who is associated with black and the joker? [[Series/KamenRiderDouble We'll see it again five years later.]] Also, a password at one point is "Double Joker." And we'll be seeing the JapaneseBeetleBrothers with a RedOniBlueOni dynamic again in ''Series/KamenRiderKabuto,'' though with the colors swapped to fit the trope better. Also, the card names are two words: the effect and the animal the sealed undead is based on. This makes the card Blade uses for changing "Change Beetle," a phrase we'll become very familiar with in ''Series/KamenRiderKabuto.''
* HoYay: A lot between Kenzaki and Hajime. Especially given the ending. Moreso given the tone and content of [[http://www.youtube.com/watch?v=M2c6r7rzxP0 this song]].
* MemeticMutation: A relatively unknown meme in the West (for obvious reasons), the Japanese have had a lot of fun with ''Kamen Rider Blade''. ''Onduru-Go'' (roughly translated as "The Ondul Language" or "Ondulish"), is a meme originating from protagonists, Kenzaki's fairly heavy-handed enunciations. The meme name comes from the first episode where Kenzaki is supposed to be saying, ''Hontou ni uragittan desuka!?'' ("Have you really betrayed us?"), but ended up sounding like, ''Onduru ruragittan disukaa!?'' Since then, it's reached a fair amount of popularity as a Japan-based net meme and has in fact received reference within the Blade AlternateUniverse episodes of ''Series/KamenRiderDecade'', as well as a shout-out in ''SuzumiyaHaruhi no Yuutsu''. It got another nod in the net movies for ''Let's Go Kamen Rider'' (the 40th anniversary movie), where the phrase that inspired the meme is the title of the episode that focuses on Blade. Kenzaki, for his part, has since been labelled the ''Kenjaki, the Prince of Ondul Planet''.
** Another aspect of this meme are the ''Blade'' emoticons ( 0w0), ( 0M0), ( 0H0), (<::V::>) and chibi Blade's going "Wa~y!" ({{Mondegreen}} from the original opening theme's "BLADE BRAVE" line, and his primary BattleCry).
** Another famous one is the shot of Garren looking out silently behind a wall from episode 1. Whenever there is a Blade related fanart, be sure to look out for this.
* NightmareFuel: The Leangle belt leaks ''spiders,'' which should creep anyone who has arachnophobia out.
** Also, children could get easily freaked out by Mutsuki when the Spider Undead possesses him.
* TheScrappy: Amane, due to being a ClingyJealousGirl for Hajime, to the point that she absolutely cannot function without him around, making her attachment to him just creepy. There's also the fact that she's incredibly disrespectful to adults, including her own mother, and especially to her uncle.
* StopHelpingMe: Done entirely for humor in the Hyper Battle Video. A Trial has impersonated Kazuma, and he asks Tachibana and Mutsuki for help. Each of them in turn says "I know who the impostor is!", pulls out his personal weapon (while not transformed)...and attacks the real Kazuma, getting him shot in the ass and bashed over the head respectively.
* TearJerker: [[spoiler:Trial B's death]].
** Also, the whole damn series finale. [[spoiler: Kenzaki [[HeroicSacrifice sacrifices his humanity to save Hajime and the world from annihilation.]] As a result, he has to stay as far away from any of his friends, including Hajime and Tachibana, as possible. [[PrecisionFStrike Fuck....]] It gets worse if you take the crossovers as canon to the Blade universe, in which Kenzaki comes back in Series/KamenRiderDecade as a completely different person, [[{{Jerkass}} and not in the good way]].]]
** Even worse is the novel continuation, where [[spoiler: Kazuma has been WalkingTheEarth for 300 years and has become a DeathSeeker because of all he's had to give up. Even worse, he can't die at all, since if he were to die Hajime would be unsealed.]]
* {{Wangst}}: Mutsuki's childhood trauma from being kidnapped and locked into a safety box as an infant was brought up early in the series, apparently reinforcing his resolve to become a Rider...at least until the trauma's resolved and the Wangst is all that remained.
