The Undead are a race of monsters in the 2004 Kamen Rider Series Kamen Rider Blade.
The Undead were 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 Undead 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.
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.

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.
Rouze Boss Jashin 14
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."
