Undead

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 madden Hirose set them free by mistake. However, the new Battle Fight was a front for a sinister plot by BOARD's chairman. Among them, there are several specialized Undead: Category Aces, the Royal Club, and the Joker.

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.

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.

Category Ace
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.

Spider
Spider Undead (スパイダーアンデッド, Supaidā Andeddo) The Spider Undead shoots webs from from his mouth to entrap his victims, sucking out their lifeforce. He is an accomplice of the Peacock Undead, appearing for Garren to seal while he spewed out golden spiders to latch on ideal hosts. Once finding an ideal host in Mutsuki Kamijō, the Spider Undead intentionally had himself sealed into the Change Spider card to complete Leangle. Though sealed, the Spider usually takes over Mutsuki's body, using him to become more powerful for the Battle Fight until he no longer needs a human host.

The Spider was forced out from Leangle during episode 42 when attempting to assume king form, with Mutsuki free of the Undead's influence thanks to Hikaru Jō giving Noboru Shima a stronger influence. The Spider was properly resealed by Mutsuki with the King Rouser. Though unsealed in Missing Ace by the Albino Joker, the Spider Undead was resealed by J-Garren.

Mantis
Mantis Undead (マンティスアンデッド, Mantisu Andeddo) Given the name "Chalice the Legendary", the Mantis Undead is the best fighter of all the Undead. As such, Hajime uses the Undead's form and assumes the identity of "Kamen Rider Chalice" while suppressing his Joker nature.

But Tennōji sealed the Undead himself into the Change Kerberos card for his true plan: Using a surgically graft 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/Keroberos II, with Blade King Form's Royal Straight Flush and Wild Chalice's Wild Cyclone to negate the fusion. However, the Griffa 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 Griffa, 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.

Joker
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.
 * 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 : 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.

Category Unknown

 * 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 blacken 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.

Trial Series
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.
 * Trial F : An Energy-Type Undead used to capture Kenzaki. Evolution Paradoxa (Category King of Hearts) Undead's DNA is used. Destroyed by Wild Chalice's Wild Cyclone.
 * Trial G : A Fighting-Type Undead which was based on Leangle's Rider data; he managed to defeat Hikaru Jō/Tiger Undead and fought off all four Riders. It was about to kill Shiori until Trial B intervened remembering the original programming his creator gave him. Destroyed by Wild Chalice's Wild Cyclone and Blade King Form's Royal Straight Flush.
