|This article is about a/an race of monsters in Kamen Rider Blade.|
The Undead (アンデッド Andeddo?) are a race of monsters in the 2004 Kamen Rider Series Kamen Rider Blade. The story of the Undead is the focus of the series as they were created 10,000 years ago by God in the form of a stone slab called the Stone of Sealing, to "kill" each other in a free-for-all battle royale known as the Battle Fight, with the winner granted a wish to alter the world.
The 52 Undead represented 52 different species and battled so they can wish for the species they represent to rule the Earth, while the Joker represented death. The losers would be sealed by the Stone itself. The winner of that battle was the Human Undead and the world has been populated by humans ever since. In the present, human archaeologists discover the sealed Undead and a maddened Hirose set them free by mistake. However, the new Battle Fight was a front for a sinister plot by BOARD's chairman. Among the Undeads, there are several specialized groups: the Category Aces, the Royal Club, and the Joker. True to their name, Undead cannot be killed as they are manifestations of different species and thus must be preserved for the next battle, so God had given them true immortality. Though Undeads are supposedly to be immortal, for some unexplained reasons, they can be destroyed by Decade as seen in Kamen Rider Decade. This could probably because Decade's power as the "destroyer of the worlds" is beyond even that of God's protection.
The Undead were designed by Yasushi Nirasawa, who later went on to create the 29 Horrors in GARO, the Worms in Kamen Rider Kabuto, and the Imagins in Kamen Rider Den-O. The Undead designs were later published in a book titled UNDEAD GREEN BLOOD. Several of the Undead have been made into collectable figurines, including the Caucasus and Tarantula Undeads, the Giraffa Undead and most recently the Peacock Undead.
There are 53 types of Undead, the same amount as a standard deck of playing cards with a single Joker.
A.R. World versions
The Undead also exist in the A.R. World of Blade. Similar to the originals, they are a race of monsters that are accidentally released from their seals and go on a rampage. Among them, there are several specialized Undead: Category Aces, the Royal Club, and the Joker. Several Undead also appear in the first episode when Natsumi is trapped within the changing dimensions. They include the Lizard, Pecker, Squid, and Caucasus Undead. In the World of Diend, instead of Jashin-14 to be controlled by Undead, it appears as a sentient villain while having Darkroaches and the whole brainwashed villagers under his control. Another Undead also made it's debut who is Bossroach (modeled after the Beetle Undead) controls several Darkroaches.
- The Paradoxa Undead (パラドキサアンデッド Paradokisa Andeddo?) is the King of Hearts Undead. He is able to create a blade-like wind from his forearm to kill his target. Normally, he is disguised as a man named Kamata (鎌田?). After being exposed in the World of Ryuki (having been taken there by Narutaki), Kamata returns to the World of Blade where he works with Hajime in a plot to take over the world as the chairman of the BOARD Corporation. After helping Hajime steal the three other Rider Systems, Kamata helps him create the Joker Rouze Card. He is later defeated alongside the Joker by Decade and Blade. Masato Irie continues to portray Kamata and provides the voice the Paradoxa Undead in the World of Blade arc. In the In the music video for "Journey through the Decade", Gackt summons the Paradoxa Undead to fight Tsukasa.
- Buffalo Undead (バッファローアンデッド Baffarō Andeddo?, 8): The Eight of Spades Undead, he terrorizes humans until Kazuma and Hishigata confront him before receiving clearance to transform into Blade and Garren. In the end, the Buffalo Undead is defeated by Blade's Lightning Blast before being sealed into the Magnet Buffalo card.
- Elephant Undead (エレファントアンデッド Erefanto Andeddo?, 8): The Jack of Clubs Undead, he is destroyed by Decade using Ryuki's Strike Vent.
- Capricorn Undead (カプリコーンアンデッド Kapurikōn Andeddo?, 8): The Queen of Spades Undead, he aids the Paradoxa Undead until he is destroyed by Decade's Dimensional Kick.
- Artificial Joker: After combining all four Rider Buckles, thus the Artificial Joker Card was created allowing Shijo to transforms into Artificial Joker Undead and dominate the Earth with the aid of Paradoxa Undead. However, Decade and Blade was able to turn the tables by using the Blade Blade to terminate the artificial Undead once and for all.
- Bossroach: Bossroach is one of the Roach enforcers who watch over the human race, whom he sees to be inferior. He controls a small portion of Darkroaches as his personal soldiers. Bossroach is then destroyed by Decade Complete Form using the Kiva Emperor Final KamenRide.
- Jashin-14: The leader of the Roaches and ruler of World of Diend, assuming the human-like form of Fourteen (フォーティーン, Fōtīn) for his "ideal peace", turning humans into mindless slaves. He commanded an army of Darkroaches as foot soldiers to enforce his will along with brain washed humans. Eventually, facing Decade and his allies, Fourteen assumes his true form before being destroyed by Decade in Complete Form with aid from Armed Hibiki, cutting him in half. After his demise, the Roaches vanish and everyone he'd brainwashed were set free.
As one of the races of the Nine Worlds, the Undead are part of the Dai-Shocker alliance, a coalition of all villain organizations fought by the Kamen Riders, who have ambitions to conquer the multiverse.
The Elephant and Giraffa Undead, as well as Darkroach, were part of the Dai-Shocker army that was fought and wiped out by a gathering of 25 Kamen Riders in the World of Decade after Dai-Shocker started their invasion of the worlds.
The Category Ace Undead are the best fighters out of the Undead, with Chalice as the strongest followed by the Spider Undead. Their cards are an important part in the Rider system, with the Riders donning armor modeled after the animals the Aces represent. All Aces appear in the series except the Stag Undead.

Unlike the previous creations, Keroberos was beyond Tennōji's control, killing his entire staff upon being born from the Stone of Sealing. The Undead succeeded in absorbing the decks of Chalice and Leangle, along with Jack and Queen cards of Garren. Keroberos even overpowered Blade King Form at first, but was defeated by Royal Straight Flush.
But Tennōji sealed the Undead himself into the Change Kerberos card for his true plan: Using a surgically grafted device based on the Rider System technology to fuse with his creation, becoming Kerberos II with Tennōji's face on the monster's chest. It took all four Riders to fight Tennōji/Kerberos II, with Blade King Form's Royal Straight Flush and Wild Chalice's Wild Cyclone to negate the fusion. However, the Giraffa Undead takes the Change Keroberos for himself in the fight's aftermath for his own agenda. Though thought to have been lost in the fight with Giraffa, the Change Keroberos was used as the Ace card for Kamen Rider Glaive in Missing Ace, with two copies of the card used in creating Riders Lance and L'arc.

However, Garren intervene and battled the Griffa Undead on his own, with his Garren Rouzer having no effect. The Undead was eventually sealed as Garren grabbed him and both plunged off the cliff they battled on.
Although called the 53rd existence, there are actually multiple Jokers much like in a card deck. If any of them were to win the Battle Fight, it would mark the end of all life on Earth, and the Battle Fight would be reset to begin anew. Jokers are armed with different weapons each; Hajime/Joker and Shijo/Joker with a green dagger, Kenzaki/Joker armed with a sword that identical to Beetle Undead's and Shimura/Joker with a staff/halberd/sycthe.
- Black Joker: The true identity of Hajime Aikawa. Technically "wins" the Battle Royale at the end of the series when Giraffa is sealed, but Kenzaki's sacrifice allows Hajime to continue living as a human and need not be sealed, with the Spirit Human keeping him in line. In Missing Ace, he was initially sealed by Blade and remained so in the four-year timeskip. After being unsealed by Leangle to protect Amane from Glaive's assault, Hajime chose to sacrifice himself in order to make Jashin 14 (then under the fully-revealed Albino Joker) vulnerable for the others to attack.
- Navy Joker (49): The form Kazuma Kenzaki assumed to put the Battle Fight at a stalemate, thereby ending it without sealing Hajime.
- Albino Joker (movie): The true identity of Junichi Shimura and villain of Missing Ace, he murdered Karasuma and stole half of the Undead, Tarantula and Giraffa among them. As Glaive, he managed to regain the two Kings and captured Amane to take her father's place as the sacrificial lamb for to invoke the power of Jashin 14 for himself, partically absorbed to it. Albino Joker was assumed to be sealed when Blade King Form's Royal Straight Flush destroyed Jashin 14.

However, Decade and Blade was able to turn the tables by using the Blade Blade to terminate the artificial Undead once and for all.
- Titan : An artificial Undead created from the Scorpion (right-half) and Chameleon (left) Undeads fused by Tennōji into one monster that had access to their attributes and two buckles on its belt. Tennōji unleashed the monster for endgame, using Scorpion's Undead Venom and Chameleon's cloaking/disguise abilities to turn the Riders against each other. By acting that he fell under the power of Joker, Hajime and the other Riders tricked Titan to reveal itself, defeating Titan by Blade King Form's Four Card with Garren and Leangle splitting Titan back into two sealed Undead.
- Darkroaches : Humanoid Cockroaches created in overwhelming numbers by the Stone of Sealing once Giraffa is sealed and Joker is the victor of the Battle Fight. They serve Joker for purpose of destroying all life on the Earth prior to the Battle Fight resetting, targeting humans endlessly. When they die, they dissolve into green mist, only to be replaced with even more Darkroaches thanks to the Stone. Once Blade became the Navy Joker, the Darkroaches existence was no longer needed.
- AlbiRoaches : White versions of the Darkroaches created by Albino Joker Undead. Though likely existing in the same purpose as their blackened counterparts, the AlbiRoaches served no higher purpose (at least in the Missing Ace film) other than aiding their master in capturing Amane.
- Rouze Boss Jashin 14 : The monstrous entity whose power is reserved for whoever wins the Battle Fight. However, it requires the life of a human who came near the slab that houses it. Amane targeted by the Albino Joker as a sacrifice place of her father who evoked it prior to his death. Once fully awaken, it was used by Albino Joker to fight the Kamen Riders until Hajime sacrficed himself to weaken it for the Blade King Form to destroy with Royal Straight Flush.
The Trial Series are artificial monsters created by BOARD, combining human and Undead DNA with machinery. They cannot be sealed with Proper Blanks; in fact, Blanks are absorbed, allowing them to recover quickly. The Trials were developed to interfere with the Undead Battle Fight. In early production sketches, they were referred as "Undeadloids."
- Trial B 39-40: An Electric-Type Undead disguised as Shiori's father, Yoshito. Originally, his program was to protect Shiori by her father because he was dying. Before he died, he transferred all his memories to the Trial. He is reprogrammed by Tennōji to continue to monitor the fixed Undead battle and remove potential threats. He dies saving Shiori from Trial G after remembering his original programming.
- Trial D : A Capture-Type Undead sent after Kenzaki, who is one card away from attaining King Form. Trial D was destroyed by Blade's King Form.
- Trial E : A Shooting-Type Undead based on Garren's data & DNA. Destroyed by Blade King Form's Royal Straight Flush. Another appeared in the Hyper Video Special Blade vs. Blade, disguised as Kenzaki wearing a red scarf, it copied the Blay Buckle and transformed into Kamen Rider Blade. He fought the real Blade to a standstill with the clueless Tachibana and Mutsuki unable to tell the obvious difference.
