Master

The is creator of the Undead and the overarching antagonist of Kamen Rider Blade. It is the administrator of the Battle Fight, who commands the Undead to fight each other and communicates through a black sealing stone called the .
==History==
During the first Battle Fight, the Monolith released the Undead and subsequently sealed them when they were defeated. During the present time, the stone was kept in Hiroshi Tennoji's possession in order to fulfill his nefarious plans, such as the creation of Kerberos. With Tennoji's death though, the Master had awakened its slumber, causing the second Battle Fight to occur.
When Joker was declared as the winner of the second Battle Fight, the Monolith releases an innumerable amount of Darkroachi. The Darkroachi begin to carry out their objective of annihilating all life on the planet, until Kenzaki mutates himself into another Joker Undead. Because there is another active contestant in the Battle Fight, the original Joker is no longer considered the winner and the Darkroachi vanish as a result. The Master commands Kenzaki and Hajime to fight one another as Undeads, with Kenzaki refusing to do so. The Battle Fight henceforth continues indefinitely.
===Kamen Rider Zi-O===
The Monolith appears once again prepared to eliminate all life on Earth after Another Blade stole Kenzaki and Hajime's Joker Undead powers, becoming the sole Undead and victor of the Battle Fight. It was eventually destroyed after Another Blade was defeated by Kamen Rider Zi-OTrinity's Trinity Time Break Burst Explosion kick because it is no longer able to sense an Undead. With the Battle Fight ended and the Blade Ridewatch having been created, the Master's role comes to an end.

*Strangely, in Kamen Rider Zi-O, the Monolith produced multiple Joker Undeads to restart the Battle Fight, rather than summoning the Darkroachi to do so.
