* 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: A few of the Undead qualify. Isaka, the Catagory Jack of Diamonds Peacock Undead kidnapped hordes of people, got Tachibana hooked on a potentially deadly plant, killed his girlfriend for just trying to help him, and brainwashed a large number of people in his quest to create the "Ultimate Rider". He never shows a hint of remorse about this in any fashion.
** The Catagory King of Spades Undead. He runs around, causing pain and suffering because he likes to. He ultimately [[spoiler:steals of of Hajime's cards to reawaken [[BiggerBad the Joker]], an OmnicidalManiac who could destroy all life on Earth.]] Why did he do it? [[ForTheEvulz For fun]].
** Ironically, the worst monster in the series is a ''human''! [[spoiler:[[BigBad Hiroshi Tennoji]] arranged for the Undead to be unleashed, knowing full well that a massive amount of death and destruction would ensue. He brainwashed Trial B, who was meant to watch over his creater's daughter, for his own selfish purposes. He ultimately created the Kerberos Undead, watching gleefully as it slaughters the scientists who helped create it. He then [[OneWingedAngel fuses with it]] in an attempt to win the battle fight, trying to kill the Riders himself. Why did he do all this? Because he wants to win the Battle Fight himself and become the [[AGodIAm God of the new world he will create]]. He does think he can make the world better, though - his version of humanity will be more peaceful. The problem? All current humans would be erased in favor of his new humanity.]]
* CreatorsPet: Mutsuki Kamijo
* 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? [[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 ''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 ''KamenRiderKabuto.''
* HoYay: A lot between Kenzaki and Hajime. Especially given the ending. And even 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 ''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.
* 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....]]]]
* {{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.
