These are the characters of the tokusatsu Kamen Rider Blade.
Kazuma Kenzaki/Kamen Rider Blade | Actor: Takayuki Tsubaki
Kenzaki was a man who was orphaned at 11 by a fire. Years later, the organization BOARD scouted him out, making him a candidate for Rider System-02, Blade. He displayed unusually high fusion coefficiency with the Undead involved in the Rider system, and eventually became the partner of Rider System-01's user, Sakuya Tachibana.
As the Battle Fight continues, Blade acquires the Rouse Absorber developed by Kei Karasuma, using it at first to assume Jack Form with the Category Jack of Spades Fusion Eagle, and then King Form, with the power of all 13 Category Spades Undead instead of merely the Category King of Spades Evolution Caucasus. This increased King Form's power at the cost of eventually turning Kenzaki himself into a Joker Undead. He uses this in the finale to allow Hajime/the Black Joker to continue living as a human, yet with him as the Navy Joker and to stay away from Hajime.
- Alien Blood: After becoming a Joker Undead, his blood becomes green.
- All-Loving Hero: He is all too loud and can be quite ill tempered, but besides that is a nice person all around. This leads him to Take The Third Option, save everyone and preserve Hajime's human existence instead of sealing him as all the other Undead. He even outrightly claimed to love everyone at one point of time.
- And then Kenzaki was an Undead: He put the Battle Fight to a stalemate by becoming the Joker himself to save Hajime so that the latter can live his life with the humans in the finale.
- Bash Brothers: He made a good team with Tachibana when they worked for BOARD and returns to that after they reconcile following Sayoko's death.
- Blue Is Heroic: Notably Blade is the first Kamen Rider protagonist with a blue color on his suit.
- Dangerous Forbidden Technique: King Form slowly turns Kenzaki into a Joker the more he uses it. He uses this to his "advantage" by overusing it in the finale to save Hajime. Since two Jokers exist, the Battle Fight can continue indefinitely.
- Foreshadowing: As Blade, he represents the Suit of Spades, with its symbol also had an inverted heart shape. The Suit of Hearts Rider is Chalice, who is none other than the Joker Undead. No guesses as to what became of Kenzaki in the final episode.
- Friendless Background: He supposedly grew up alone and calls Kotaro his first friend, but doesn't always understand what it means to have friends.
- The Hero: This is obvious as the story's main protagonist.
- Heroes Prefer Swords: The Blay Rouzer and King Rouzer. It's all in the name, after all.
- Hurting Hero: He blames himself for not being able to save his parents and is motivated to protect anyone he can. It's also hard for him to comprehend that someone actually actually cares about him too as evident by his confusion when meeting Kotaro and Shiori's concern about him.
- Ineffectual Loner: Before the show. After his parents died, he was cold and antisocial, and didn't have friends. He outright calls Kotaro his first. Over the course of the show, the exact opposite happens, with him reaching out to everyone. Some of his previous attitude remains in his inability to comprehend that people want to reach out to him too.
- Irony: His Tackle Boar attack is almost always evaded by any enemy it's used against due to how predictable it is. The one time it does work is during the Hyper Battle DVD, where it's used against him by the fake Blade.
- Kiai: Kenzaki shouts A LOT. Nearly every attack is punctuated by his screams, and he's become well-known for them by fans.Kenzaki: WAAAAAAAAAAAAAAEEEEEEEEEEEY!
- Knight in Shining Armor: Becomes one for two episodes to an orphan girl. His default form already refers to a knight, anyway. King Form too, despite be, well, a king.
- Last-Name Basis: He is always adressed as Kenzaki. Only his family called him Kazuma.
- Meaningful Name: Called "Blade" because he uses Category Spade cards, aka "The Suit Of Swords".
- Motif: Hercules Beetle and the Suit of Spades. Eventually the cockroach, being the Joker.
- Power of Friendship: His means of reaching out to people is convincing them he cares and that caring about someone is awesome.
- Red Oni, Blue Oni: The red to Tachibana's blue, despite their suit's colors. He is also the red to Hajime's blue.
- They Call Him "Sword": They call him Blade.

Sakuya Tachibana/Kamen Rider Garren | Actor: Kousei Amano
Later, he manages to be manipulated by Isaka/Peacock Undead for the latter's sinister plans, until it is revealed that Isaka killed his girlfriend Sayoko Fukasawa. With this he defeats the Undead and in repentance takes Mutsuki/Leangle under his wing. In the Final Battle, he fights the Category King of Diamonds Giraffa, until it ends with Garren nowhere to be seen and the Giraffa Undead sealed. But returns in the finale.
- Bash Brothers: He made a good team with Kenzaki when they worked for BOARD and returns to that after they reconcile following Sayoko's death.
- Brainwashed and Crazy: When under Isaka's control. He doesn't listen to anything but the order given and doesn't react to anything else but extreme circumstances.
- Broken Pedestal: Kenzaki really looked up to him as BOARD's senior rider. Their relationship got complicated after Tachibana's apparent betrayal of BOARD and seriously hurt him.
- Deal with the Devil: He takes up Isaka's offer to make him stronger and fearless. He didn't know neither that it would give Isaka a mental leash through which he could control him nor that it's addictive and fatal.
- Foil: Being the series' Second Rider, he serves as one to Kenzaki, both their motifs are based on a beetle sub-species, with Garren being based on a Stag Beetle to match Blade's Rhinoceros Beetle motif, along with their color of their rider forms are contrasts to each other. Not to mention unlike the All-Loving Hero Kenzaki, Tachibana is not hesitant to seal the Undeads if it needs neccesarily.
- The Gunslinger: Once an Episode. He is a gun toting Kamen Rider. Of course he does something cool.
- I Let Gwen Stacy Die: Sayoko. He feels guilty for not being able to stop Isaka from killing her. This leads to him taking Mutsuki in as an atonement.
- Last-Name Basis: Everyone calls him Tachibana. Even his girlfriend!
- Lost Lenore: Sayoko supported him and researched Isaka's means of controlling him and her words motivated Tachibana to fight the control. Needless to say, it didn't end well for her.
- Meaningful Name: Called Garren (Galleon) because he's of the Suit of Coins.
- Mentor Archetype: He does his best to make Mutsuki a proper Kamen Rider and help him overcome the Spider Undead's control, but to mixed reasults that are not improved by Mutsuki himself.
- Motif: Stag Beetle and the Suit of Diamonds.
- Older and Wiser: He has been a Kamen Rider for longer than Kenzaki, who looks up to him greatly before Tachibana's apparent betrayl of BOARD.
- Red Oni, Blue Oni: The blue to Kenzaki's red, despite their choice of colors.
- Roaring Rampage of Revenge: After Isaka kills Sayoko, he goes on one. He finishes it by taking down the previously undefeatable Peacock Undead.

- Glass Cannon: Jack Form, which also counts as his Super Mode.
- Jack-of-All-Stats: Ace Form.
- Playing with Fire: Category Six Fire Fly.
- Swiss Army Weapon: His Garren Rouzer already allows him to access his abilities aside from being a gun, but Jack Form transforms it into a gunblade for melee combat.
Hajime Aikawa/Kamen Rider Chalice | Actor: Ryoji Morimoto
A mysterious photographer living with the Kurihara family, with the ability to become a Kamen Rider. In reality, the alter ego of the Black Joker Undead, whose victory in the Battle Fight would cause The End of the World as We Know It. He uses the Category Ace of Hearts Change Mantis to assume the form of Kamen Rider Chalice, and the Category Two of Hearts Spirit Human to assume a human form. The combination of the Mantis Undead's fighting spirit and the Human Undead's compassion helped to control his natural impulses as the Joker. After witnessing a man's death at the hands of one of the Royal Club Undead, he vows to protect the man's family adopting the persona of Hajime Aikawa. After the Caucasus Undead steals most of his cards, including the Category Ace of Hearts Change Mantis, he begins to regress into his Joker form, with Leangle unsealing his cards in an attempt to control him. The Joker continues to rampage, however, until he acquires the Evolution Paradoxa card, allowing him to access Wild Form.
By series end, with all other Undead sealed, he regresses to his true nature as the Black Joker, dooming life on Earth. Eventually Kenzaki takes it upon himself to defeat Hajime, not by sealing him (though this provides the plot of the Missing Ace film), but by becoming a Joker himself, allowing Hajime to resume living as a human with the Kuriharas.
- Abomination Accusation Attack: He is accused of murder by family friend of Kuriharas and when she digs in to confirm her suspicion, she finds out he might not even be human. That and her seeing him transform in Chalice leads up to the accusation of being a monster out to destroy the world. It's all explained in the end, but she was right in the second point. He is a monster out to destroy the world. He doesn't want to, but it's not in his control.
- Alien Blood: Green in his case, the main visual clue he is an Undead.
- Ambiguously Human: He is initially introduced as an unassuming tenant of Kuriharas, but it's soon revealed he has green blood and fights as Chalice. Not only he is an Undead, he is Black Joker.
- All Your Powers Combined: The Wild Card combines the powers of all the cards in the Suit of Hearts.
- Anti Anti Christ: His victory in the Battle Royale will lead to the destruction of all life on Earth, whether he wants to or not.
- And I Must Scream: He has only little control of over his actions when dominated by his Undead Instincts or forced to revert into Joker. He managed to improve his chances a little over the time with Heroic Will Power and Power of Friendship.
- Becoming the Mask: Hajime , who assumed the appearance of the Human Undead, was initially only Intrigued by Humanity, but found himself enjoying his new life with the Kuriharas.
- Death Glare: The peak of his Perpetual Frowner attitude he reserves for people who get too close. He gets some truly scary expression when his insticts react to the Undead active in the area or worse, when that Undead specifically calls out to him.
- Death Seeker: When the world's destruction starts in the story's finale, he just waits for someone (namely Kenzaki) to seal him to save the world he couldn't protect.
- Despair Event Horizon: He crossed it after being forced to revert into Joker Undead and start world's destruction. It doesn't matter how much he fought to keep it from happening. When Kenzaki and Mutsuki find him, he would let them seal him if he had any say in that. He wanted to protect Haruka and Amane at first, but then he gave up even on that to spare himself the pain and just waited for the world to burn or for someone to come and seal him.
- Deuteragonist: Despite being the series' Third Rider, Hajime's relationship with Kenzaki is the most important relationship the latter has in the series. He receives second billing in the main credits, is the only Rider in the series to receive a Final Form (Wild Chalice) other than Kenzaki, and much like Kamen Rider Kabuto years later, his actor is the singer for the series' Final Form Battle Theme (take it a try). As an added parallel, both Blade's and Chalice's elements complement each other, representing the pair of Japanese gods, Raijin and Fujin.
- The Dreaded: Undead flee from him in Joker form.
- Driven to Suicide: When he is forced to turn back in Joker and be the vector of the world's destruction, he tries to kill himself to stop everything. It doesn't work because Undead are immortal. Kenzaki and Kotaro find him a while later, sobbing.
- Eldritch Abomination: Being the Joker Undead, he is massively more powerful than any of the other Undeads, and his victory in the Battle Fight guarantees the end of the world. Design-wise he also one of the more unnerving appearances, with a moveable jaw and ghastly white skin coloration.
- Greater-Scope Villain: While the other Undead and Hiroshi Tennoji set up the events of the plot, it is the Joker's existence that threatens life on Earth.
- Ineffectual Loner: He tries to be cold and antisocial, but the combined influences of the Spirit Card, Amane's attachment and Kenzaki's attempts to reach out to him all make his cold facade crumble.
- I Cannot Self-Terminate: He tried to commit suicide in the story's finale, but failed because Undead are immortal. He can't seal himself either because the Stone of Sealing would stop him.
- Identical Stranger: In his human disguise, Hajime shares the same face with a civilian named Ryo Mikami.
- Intrigued by Humanity: This is supposedly his reason for agreeing to look after Kuriharas. The most interesting thing to him is that humans care and act selflessly, unlike Undead, who are self centered pragmatists by default, even if exceptions exist.
- Jerkass -> Jerk with a Heart of Gold: He starts as a cynical loner hostile to everyone but his human family, but gradually changes into someone, who considers Power of Friendship and emotions to be humanity's strength and tries to reach them himself. Granted, mellowing out doesn't stop him from keeping a cold edge to his attitude, a frown as his default expression and a reserved approach to anyone that is not Haruka, Amane or Kenzaki.
- Mad Laugh: He has a sad, only slightly unhinged one after crossing Despair Event Horizon in the finale.
- Meaningful Name: Called Chalice because he's of the Suit of Cups, and also because the Mantis Undead he's using to assume Rider Form was also called Chalice.
- Hajime means beginning, an ironic name for someone supposed to cause The End of the World as We Know It. But it also meaningful since he , as the Joker, marks the beginning of a Battle Fight.
- Motif: Mantis, Suit of Hearts, and the cockroach, when being the Joker.
- Perpetual Frowner: Early into the story Death Glare is basically his default face. He is considerably more mellow around Kuriharas and slowly softens up in regards to Kenzaki too. The scowl still remains, though.
- Say My Name: Many times he says Kenzaki's name are meaningful in some way. He mostly does it only if it's meaningful, sad or soemthing along those lines.
- Sealed Evil in a Can: His form of the Black Joker is kept sealed by the spirits of Human and Mantis Undead.
- Voluntary Shapeshifting: The Chalice Buckle can be used to facilitate this; Hajime normally uses it to transform into his Rider form or his human form, but it can be used to transform into other Category Heart Undead.
- What Is This Feeling?: His grasp on feelings is limited at best and he doesn't understand why humans care about each other even though he himself cares about Haruka and Amane. When Kenzaki offers to help him, his first reaction is to ask what he would receive from that.
- He even asks this nearly verbatim when feeling sad after leaving the Kuriharas for a time to protect them.
- When He Smiles: His human side definitely shines through at that moment.
- Woobie, Destroyer of Worlds: He seems to be unable to stop himself from destroying all life, but ultimately he's forced to do so. Until Kenzaki intervenes...
- Wild Card: Literally and figuratively. Aside from nobody knowing his motives at the beginning of the series and switching on and off between being a normal hero and an Anti-Hero, he's the Joker Undead (which is the card usually called the wild card) and his final form is even called Wild Form.
Tropes exclusive to the Ark as Kamen Rider Chalice
- Bifurcated Weapon: Wild Slasher, which can used as a bow or be split into two kama.
- Blow You Away: Category Six Tornado Hawk.
- Cool Bike: The Shadow Chaser, used as a prototype for the BOARD-made bikes.

- Flight: Category Four Float Dragonfly.

- Spinning Wave: Combines the Category Three Chop (Hammer)Head and Category Six Tornado Hawk to execute a wind-based karate chop.
- Spinning Attack: Combines the Category Five Drill Shell and Category Six Tornado Hawk to execute a wind-based corkscrew kick.

- Threatening Shark: Category Three Chop (Hammer)Head.
- Weapon of Choice: Wild Slasher, a bow/blade combo.
Mutsuki Kamijo/Kamen Rider Leangle | Actor: Takahiro Houjou
With the sacrifices of the Tiger and Tarantula Undeads, Mutsuki is able to overcome the Spider Undead's evil influence. With Garren nowhere to be found after the Giraffa Undead's unsealing, he assists Blade in dealing with the Darkroaches as Blade himself goes and faces Hajime as the Joker.
- Blood Knight: The Spider Undead will fight anything and anyone at any point, even long after it has been sealed. Saying that it's problematic for Mutsuki whose body it uses to realize these wishes would be a major understatement.
- Brainwashed and Crazy/More Than Mind Control: Spider Undead's control of him usually falls into these tropes. It can directly take over Mutsuki's body, but its grip is too fragile to mantain in battle for extended periods of time. So he whispers in Mutsuki's mind, pressures him into following selfish desires and slowly takes firmer grip on his body and mind through his own insecurities.
- Can't Catch Up: While his Ace Form is the most powerful of all Riders, he lacks a Super Mode.
- The Chosen One: He was picked by the Spider Undead as the perfect user for the Leangle belt. Mutsuki wanted to be a chosen one and considers it his fate, but he hadn't expected the fate to twist and get him possessed by a blood thirty monster that keeps on snuffing out his self with each day. Still, he accepts his fate as it is.
- Comes Great Responsibility: Tachibana has rightfully accused him of treating the fight as collectible card game. Mutsuki is a good kid at heart, but has a problem with needing to prove his strength to himself and by extension everyone around so he naturally doesn't always think with people's best interests or strategically at all.
- The Corruptor: Spider Undead tries to take stronger hold of him by poisoning his mind and forcing him to give in his own desires. Much of Mutsuki's problems stem from the fact he doubts himself and is not as selfless as Kenzaki or Tachibana.
- Dating Catwoman: Sort of. While corrupted and deprived of his best judgement, have Tiger Undead by his side is unironically one of the things that keeps Mutsuki from fall totally to Spider Undead's grasp.
- Death of Personality: Spider Undead is bleeding into his mind, blurring the line between them so it's hard to say what was done by Mutsuki under the influence and what was done by Spider Undead. One of his lucid moments has Mutsuki tell Tachibana he is afraid that the Spider Undead will completely destroy his self and obtain absolute control of his body and mind.
- Demonic Possession: By Category Ace Spider Undead that can grab control of people if they so much as look at the card it is sealed in. Being its Chosen One means only suffering for Mutsuki.
- They Call Him "Sword": They call him Leangle.
- I Just Want to Be Normal: In Missing Ace movie. He tries to move on with his life, and was quite upset when Kenzaki and Kotaro tell him that Undead might return.
- Motif: Spider and the Suit of Clubs.
- Mind Rape: Spider Undead deals it out in heaps and Mutsuki rarely has enough willpower to at least slow it down. He describes it to Tachibana as it tirelessly whispering in his mind, forcing him to fight and kill.
- Meaningful Name: Called Leangle because he's of the Suit of Wands, the clubs.
- Smug Snake: While influenced by the Spider Undead.
Tropes exclusive to the Ark as Kamen Rider Leangle
- Blade on a Stick: Leangle Rouzer.
- Finishing Move:
- Blizzard Crush: Combines the power of Category Five Bite Cobra and Category Six Blizzard Polar to execute an ice-based scissors kick.
- Blizzard Gale: Combines the power of Category Three Screw Mole and Category Six Blizzard Polar to execute an ice-based punch.
- Blizzard Venom: Combines the power of Category Four Rush Rhinoceros, Category Six Blizzard Polar, and Category Eight Poison Scorpion to deliver an icy poisoned strike with the Leangle Rouser.
- An Ice Person: Category Six Blizzard Polar.
- Lightning Bruiser: His Ace Form has the best stats of the four. Comparatively, his SIC-figure-only Jack and King forms are...
- Mighty Glacier: Not seen in-show, but the stats and appearance of his SIC-only Jack◊ and King◊ forms indicate that it trades speed and agility (Leangle Jack's jump height is listed less than one-fifth of Blade Jack's!) for sheer overwhelming power. Additionally, unlike the other Jack forms (not counting Chalice's Wolf Undead form) it lacks the ability to fly.
- Panthera Awesome: Category Queen Absorb Tiger.
- Poisonous Person: Category Eight Poison Scorpion.
- Smoke Out: Category Nine Smog Squid.
- Summon Magic: Category Ten Remote Tapir; allows Leangle to unseal an Undead to aid him.
- This Is a Drill: The card combo Category Three Screw Mole and Category Four Rush Rhinoceros makes the Leangle Rouzer one.
Shiori Hirose | Actor: Yumi Egawa
One of the few remaining BOARD members after the attack on the organization, she sets up a command post at Kotaro's residence in order to help Kenzaki track down the Undead.
- Brainy Brunette: Naturally, as a BOARD scientist. She understands the technical parts of the Rider technology and functions as the mission control.
- Beleaguered Assistant: Her help with fighting Undead puts her up as a sidekick, not assistant. She is nearly constantly annoyed with Kenzaki and Kotaro and occasionally with other people and stuff going on.
- Mad Scientist's Beautiful Daughter: Arguably, after the reveal that her father Yoshito programmed the Trial B Undead to watch her, assuming himself as a disguise.
- Mission Control: Sort of. Using the Undead Searcher she instructs Kenzaki on where to find Undead once they attack people.
- It's All My Fault: She thinks that since her father took part in releasing the Undead to save her and her mother, she is also guilty.
- Perpetual Frowner: Her most usual expression is a scowl of annoyment or concentration. She smiles... rarely, that's for sure. It matches her attitude of Beleaguered Assistant.
- Super Strength: One thing, she is stronger than Kotaro. Other thing, she can haul several crates of milk bottle at once without breaking a sweat and tilt a fridge by pushing with a one hand and no effort at all.
- Team Mom: Her usual attitude towards Kotaro and Kenzaki. A bossy, angry mom, but cares about them more than she shows.
Kotaro Shirai | Actor: Terunosuke Takezai
An aspiring writer with whom Kenzaki moves in after the latter failed to pay his rent. He likes drinking milk.
- Butt-Monkey: Primarily from either Shiori, Hajime, or Amane.
- Comically Missing the Point: Hirose warns him that he will turn into a cow (which she considers terrible) if he keeps on drinking so much milk, he just answers it'll be cool because he can drink his own milk then.
- Distressed Dude: Let's just say that he fell in love with the wrong woman.
- Contrasting Sequel Main Character: Kotaro the same position as Keitaro as the comic relief support character that befriends the main Rider and takes him in to live with him and gets rejected compatability into being a Rider. However, what contrasts them is with their love lifes: Keitaro's crush is one of the main characters and part of his defining traits and arc involve miscommunications between them and once he found out about her beign a monster, he continued to accept her as his girlfriend all the way to her death while ending on good terms with her; Kotaro, on the other hand, had a crush who was a cunning Undead who feigned kindness towards him and even after how she treated him, he hospitalized her but Hajime coming to their direction ended with the two not ending on good terms as she got sealed, although Kotaro managed to have some admirers due to his wealth in The Movie.
- The Load: He considers himself this because of his status as the Non-Action Guy and it drives him crazy with despair sometimes.
- Nerves of Steel: Actually has much more courage than he would ever think. He put himself between two fighting riders to stop them and would rather let an Undead strangle him than have Kenzaki surrender his belt.
- Non-Action Guy: He does everything he can to help the Kamen Riders but he is not fighter, or scientist, so his scope is somewhat limited. He can deliver a good pep talk or be extra hands or legs for someone (usually Hirose).
- Real Men Wear Pink: He doesn't mind wearing pink shirts on occasion.
- Refused by the Call: Noone of the Category Ace Undead would fuse with him, so he can't be a Kamen Rider. He is not a scientist. No matter how desperately he would want to be helpful, stronger and relevant to the struggle between humans and Undead.
- Team Chef: For the household and the people who pass through like Tachibana. His cooking is pretty good, but can have lapses in quality if he feels too bad about something. Like having his heart broken by an Undead.
- Trademark Favorite Food: He orders milk by the crate and has a full fridge of bottles.
Haruka Kurihara | Actor: Kaori Yamaguchi
Kotaro's sister and Amane's mother.
Amane Kurihara | Actor: Hikari Kajiwara
A young girl who befriends Hajime, and makes the mysterious man discover what it is to be human.
- Bratty Half-Pint: Downplayed example. She is a good kid, but tends to pout or misbehave when not given what she wants or when someone (mostly Hajime) annoys her.
- Delinquent: Became one in the Missing Ace film, since Hajime was sealed by Kenzaki prior to the film.
- Disappeared Dad: Her father was fatally wounded by an Undead and asked Hajime to take care of his family.
- Morality Pet: To Hajime, but became a Delinquent in the Missing Ace film when he is not around.
Nozomi Yamanaka | Actor: Arisa Miyazawa
BOARDThe Board Of Archaeological Research Department developed technology to combat the Undead, making the first two Rider Systems and their support gear. Is destroyed in the first episode after Tachibana's apparent betrayal.
Kei Karasuma | Actor: Kazuhiro Yamaji
A professor who created the Rider Systems 01 (Garren) and 02 (Blade), as well as 03 (Leangle) under the directions of Isaka the Peacock Undead. He entrusted the Rouse Absorbers to Noboru Shima, despite knowing of the latter's nature as an Undead. He also knows of the secret that Blade's King Form has...
Yoshito Hirose | Actor: Junichi Haruta
Shiori's father, who unsealed the Undead, seemingly being killed in the process. Turns up later seemingly alive, only for him to be revealed as the Trial B Undead, originally programmed by the real Yoshito Hirose to protect his daughter. However, Tennoji reprogrammed him to monitor the Battle Fight, but after sacrificing himself to protect Shiori from Trial G, he remembers his true purpose.
- Half-Human Hybrid: Trial B, like all other Trial Undead.
Hiroshi Tennoji | Actor: Koji Moritsugu
Chairman of the BOARD organization. Set up the Battle Fight in his favor, and created the hybrid Undead Category Ace Kerberos, wishing to use it to rule the world. While he manages to create (and eventually fuse) with Kerberos, he is killed by the Giraffa Undead after his defeat at the hands of the Riders.
- Big Bad: While not the final villain, everything bad in the series is pretty much his fault.
- In Their Own Image: His ultimate goal is to win the Battle Fight and gain the power to reshape the world in his own image.
- The Man Behind the Monsters: Controls some of the Undead directly and a few of the Trials, but arranged the release of all of them in the first place.
- One-Winged Angel: Merges with the Kerberos Undead in order to be the victor of the Battle Fight.
- Too Dumb to Live: Maybe Tennoji should've just left the area instead of holding onto Kanai, chanting the Riders to seal him, if he wanted to live and continue his scheme for another day.
- Villainous Breakdown: He has a complete mental breakdown upon his defeat, ranting about his "new world" and how the two remaining Undead must be sealed so it can happen.
- Walking Spoiler: Pretty hard to talk about him without mentioning his role later on.
UndeadUndead are the kaijin of the show. There are 52 or rather, 53 Undead each competing in the Battle Fight, with the victor's species gaining dominance over the world. The winner of the previous Battle Fight ten thousand years ago was the Human Undead, resulting in the dominance of humanity.
Most of the "numbered" Undead are only capable of speaking their own language; however, those belonging to the so-called Royal Club can take on human disguise and speak human languages like Japanese. Their motivations are diverse and complex, from one fond of humanity (Tarantula Undead/Noboru Shima) to one with very sinister designs (Spider Undead).
- Bat Out of Hell: Category Eight of Diamonds Bat Undead.
- Bears Are Bad News: Category Six of Clubs Polar Undead.
- Bee Afraid: Category Two of Clubs Bee Undead.
- Beware the Nice Ones: Noboru Shima/Tarantula Undead aka the King of Clubs, is perhaps one of the nicest characters in the series. The biggest example though is the Human Undead, an incredibly kind person who is merely the 2 of Hearts... Yet he was the one who won the last Battle Fight, even sealing THE JOKER HIMSELF.
- Bewitched Amphibians: Category Three of Diamonds Frog Undead.
- Complete Immortality: The Undead cannot die, only be sealed.

- Arc Villain: From episodes 5 to 15.
- The Corrupter: Deceives Tachibana into working for him by telling him that Schuld Kestner seaweed can eliminate fear and by soaking him in a watered glass container full of it.
- He Knows Too Much: When Sayoko took notice of his actions, Isaka threatened her with a warning that he would end her if she kept on interfering. Sayoko continued to try to help Tachibana out of his predicament, resulting in Isaka making clear on his promise.
- Hoist by His Own Petard: His murder of Sayoko eventually resulted in Garren curb-stomping him and sealing him.
- Irony: Spider Undead was sealed by Tachibana on the order of Isaka, who was trying to create a perfect rider. Despite all the time and effort he has invested into creating the Leangle belt and arranging for Spider Undead to be sealed, he never got to see said rider, let alone use him, as he was sealed by Tachibana shortly after. Still, his influence stretches much further into the story.
- Mad Scientist: If conducting experients, creating a Rider belt, putting Tachibana in a water tank of seaweed to get him in his control, and testing Leangle's power on several teenage boys he had kidnapped are any indication.
- Manipulative Bastard: Has manipulated Tachibana and several workers to help him in his schemes.
- Mind Manipulation: The very workers that helped him in his schemes were revealed to be brainwashed by him and have no memory of what they were doing in episode 16.
- Small Role, Big Impact: Even as the first of the Royal Clubs to sealed, his actions of finding a suitable candidate for Leangle resulted an improperly sealed Spider Undead eventually finding its way into Mutsuki and corrupting him, prompting Kenzaki and the others to struggle in trying to free him for almost the rest of the series.
- The Sociopath: Isaka doesn't exhibit any genuine emotions, brainwashes and manipulates those he sees fit for his plans, and disposes of those who stand in the way of his schemes.
- This Cannot Be!: Once Garren finally defeated him, also doubled as his Famous Last Words.
Miyuki Yoshinaga/Orchid Undead | Actor: Mika HijiiThe Category Queen of Hearts Undead.
- Arc Villain: From episodes 20 to 25.
- Bitch in Sheep's Clothing: First introduced as a Nice Girl who ended up being Kotaro's girlfriend, but in reality was trying to lure him into a trap to kill him.
- Dark Chick: While not the only female of the Royal Clubs, she otherwise fits this trope often emotionally manipulating others into doing her bidding and acting nice.
- Even Evil Can Be Loved: Despite how she treated him, Kotaro saved her and believed she can change and was extremely upset at Hajime for sealing her.
- Evil Cannot Comprehend Good: When Kotaro saved her and hospitalized her in her car, being unable to cope with human emotion, she questioned his act of kindness, even telling her of how she treated him and that she's an Undead.
- Evil Is Not a Toy: After seeing Daichi trounce 3 of the Riders without a flinch, Miyuki decides to lure Hajime to the pool area in hopes that the Rider gets minced by her fellow Royal Club. After Daichi knocks Hajime down, he notices Miyuki watching them, which prompts her to run away and get chased by him.
- Faux Affably Evil: Miyuki acts kind and gentle but deep down only cares about herself, having manipulating those into doing her dirty work and betraying/striking on whoever has their guard let down.
- Hoist By Her Own Petard: Lured Hajime into Daichi's location, resulting in the two fighting when her fellow Undead noticed her watching them. When Daichi confronted her of her action, stating it very clear to her that he didn't like to fight much, she feigned an apology to him in order to let his guard down, but he eventually overpowered her and she was left injured.
- Manipulative Bitch: She often makes others who she alliances with to do her dirty work and feigns being kind towards Kotaro and later Mutsuki.
- Technopath: Jammed the signals of the Undead Searcher when Shiori allowed her to use it.
- Too Dumb to Live: Knocked Kotaro out once Chalice finds her, with Miyuki assuming her Undead form to fight him while she was still recovering from her injuries from Daichi. Thus, Hajime was able to easily curp-stomp her and seal her in spite of Kotaro's objections. Honestly, had she not engaged in battle at that point, she would've lasted longer in the modern Battle Fight.
Yazawa/Capricorn Undead | Actor: Atsushi KorechikaThe Category Queen of Spades Undead.
- Affably Evil: While genuinely evil, he acts somewhat laid-back and chill with Kenzaki.
- Even Evil Has Standards: Downplayed. Yazawa complained about Miyuki's cunning nature while he was enraged about her not helping him in the chance to finish off Blade but still continued to help her after being told of Kenzaki's soft heart with Kotaro.
- Extreme Omni-Goat: His animal motif and is a rather rash Undead.
- Make Me Wanna Shout: Is rather loud pitched and screeches in his Undead form against his opponents.
- That One Guy: The only male Queen Undead.

- We Hardly Knew Ye: Like Yazawa, he only lasted in the two episodes he appeared in.
Shinmei/Wolf Undead | Actor: Masashi KagamiThe Category Jack of Hearts Undead, proclaiming himself to be an "Undead Hunter".

- Badass Biker: Shown to be a very excellent motorcyclist when riding the Black Fang.
- Evil Laugh: After Tachibana ousted him in his true nature and goals.
- Idiot Ball: Had Shinmei not attempted to maim Kenzaki behind his back after the latter complimented him, then he wouldn't have been exposed by Tachibana.
- I Lied: Called himself an Undead Hunter who takes down the mysterious werewolves and asked Kenzaki, Tachibana and his fellow Undead Hunters to help him with finishing the Black Fang. Once it was finished, Shinmei promptly used it to finish off his own men, with Kenzaki and Tachibana enraged for Shinmei's actions towards them, especially since he was the one who turned many of his victims into those werewolves.
- Mole in Charge: Infitrated human society and started the Undead Hunters for his schemes.
- We Hardly Knew Ye: Has the same two-episode deal Yazawa and Takahara had.
Daichi/Elephant Undead | Actor: Kairi NaritaThe Category Jack of Clubs Undead.

- The Bus Came Back: Briefly unsealed by Mutsuki in episode 45 to help him against Kerberos, only to be resealed again.
Noboru Shima/Tarantula Undead | Actor: Kazunari AizawaThe Category King of Clubs Undead and an old friend of Karasuma in Tibet.
- Empathy Pet: Owns a yellow canary bird named Natural.
- Graceful Loser: When Mutsuki defeated him, Shima imperatively tells him to seal him while questioning him if he wanted world peace and to fight for justice.
- Spanner in the Works: Karasuma entrusted him the Rouze Absorber, which he later gave to Kenzaki for him to use Jack Form to defeat and seal Daichi. Shima even got himself intentionally struck by Mutsuki to get sealed by him in order to undo Spider's corruption of him. Of course while he was sealed, it didn't have any effect of freeing Mutsuki from Spider's control until Hikaru also got sealed.
- Token Good Teammate: The most pacifistic and friendly of the Royal Clubs, wanting peace for humanity and Earth.
Azumi/Serpent Undead | Actor: Mio FukuzumiThe Category Queen of Diamonds Undead.
- Evil Laugh: Much of her screentime has her doing this and does this much more than the other Undead.
- Filler Villain: Her duration in the show was during a Breather Arc of Hajime's amnesia and meeting his lookalike who is a takoyaki maker.
- Medusa: Her Undead appearance pretty much has that resemblance.
- Not in the Face!: Ryo ended using a takoyaki plate while it was hot and slammed it on her face while she was in Undead form, causing Azumi to writhe in pain.
- We Hardly Knew Ye: Yet another Royal Club Undead that lasts unsealed for two episodes.
King/Caucasus Undead | Actor: Makoto KamijoThe Category King of Spades Undead.
- It Amused Me: Enjoys causing trouble and messing with others with his phone.
- Jacob Marley Warning: Before being sealed, he smugly warns Kenzaki to be careful or he would end up controlling him like what happened with Mutsuki.
- Laser-Guided Karma: His demented take of amusement by messing with others bites him back when the same method was used against him in front of a crowd.
Hikaru Jo/Tiger Undead | Actor: Akane HamasakiThe Category Queen Of Clubs Undead.
- HeelFace Turn: Helps the heroes and Nozomi by allowing Mutsuki to seal her once she ended up defeated. It was because of her being sealed that freed Mutsuki of Spider's influence and she and Shima tell him in his subconsciousness to fight with both light and darkness.
- Love Redeems: Ended up having feelings for Mutsuki, enough for her to intentionally get herself impaled and then sealed.
- Noble Demon: Possesses great pride and fights with dignity, and is usually a more honorable fighter.

Ace RidersThree Riders from The Movie, Kamen Rider Blade Missing Ace, created by BOARD, using the Change Kerberos Rouze Card created from sealing the Undead.
- Expy: An in-series example, as all 3 are based on the TV Riders - Glaive to Blade, Larc of Garren and Chalice, and Lance of Leangle.
Junichi Shimura/Kamen Rider Glaive/Albino Joker Undead/Jashin 14 Actor: Yuuki KurotaThe first of the 3 Kerberos Riders, notable for using the original Change Kerberos card. In reality, he's a second Joker Undead, having hidden in the shadows during the events of the TV series.
- Antichrist: Unlike Hajime, who didn't want to end the World, Junichi has no such qualms.
- Big Bad: Of Missing Ace.
- Bitch in Sheep's Clothing: Junichi helps children with fundraising and is the identity of the Albino Joker.
- Cool Sword: The Glaive Rouzer, which itself is based on the Blay Rouzer.
- Evil All Along: Presents himself as a hero at first. In reality, he's the film's Big Bad.
- Evil Counterpart: To both Kenzaki and Hajime. In terms of power sets, Glaive's arsenal was based on Blade's, while his Undead form is a stronger variation of the Joker.
- Finishing Move: Gravity Slash, using the Mighty Gravity Rouze Card.
- Light Is Not Good: The Albino Joker and Jashin 14 are both mostly white. But they're definitely evil.
- Logical Weakness: Power-wise, he's as strong as Blade's base form. However, since he lacks a Rouze Absorber, he lacks a counter for Blade Jack Form.
- Unskilled, but Strong: Due to spending the majority of his time in the shadows in the timeline Missing Ace came to be, he didn't fight as much as the other Undead, leading him to become this trope in comparison to Hajime, who did fight...but due to having been sealed for a while in the backstory of Missing Ace, was seriously weakened by the time the two fought in that movie.
- Walking Spoiler: Try discussing him without mentioning his true role in the movie.
Natsumi Miwa/Kamen Rider Larc Actor:Yoko MitsuyaThe second of the 3 Kerberos Riders, using a copy of the Change Kerberos Card.
