Kamen Rider Diamond Warrior

Kamen Rider Diamond Warrior is a Rider in the fanfictional series Kamen Rider: Spade Warrior.

Kent
Kent was chosen by the BOARD organization to use the very first Rider System they created, transforming him into Kamen Rider Diamond Warrior.

Forms
For Kent to change into Diamond Warrior, he inserts the sealed Ace of Diamonds (Category Ace: Change Stag) card & position the buckle in front of his waist. The belt expands automatically around his waist, like a deck of cards wrapping around. Kent makes an arm motion, clinches his fist & yells out "Kamen Rider!" & flips a portion of his buckle. The buckle announces "Turn Up!" at this point. This causes a blue projection with a stag beetle image to come out before him, knocking Undead away. he then runs into the projection, which will complete the transformation into Diamond Warrior.

Diamond Buckle
Designated "Rider System 01", this transformation device was the first Rider System developed by B.O.A.R.D. intended as a mean to combat the Undead via the fusion of Undead DNA & human DNA. The Diamond Buckle was designed for specific compatibility with the A: "Change Stag" Rouse Card & harnesses the DNA of the Stag Undead. This model utilizes the "Turn-Up" mechanism to produce a stationary transformation screen, which initiates the fusion of Undead DNA with a human to produce the Kamen Rider transformation. Coincidentally, the transformation screen itself can act as a deflective wall against assaults.

Diamond Rouzer
Diamond Warrior’s primary armament; a hi-tech gun which serves as a weapon for combat & storage unit for Rouse Cards, including Proper Blanks. It has a built-in 'rousing' technology, which enables Diamond Warrior to "rouse" the sealed Undead's power to utilize personally. After activating Jack Form, the Diamond Rouser gains an enhancement in the form of a blade forming on the barrel to be let the weapon be used for close-range attacks.

Diamond Absorber
A special accessory developed to bolster the Rider’s capabilities. The Rouse Absorber was designed to be a supplementary Rouse device to the Rider System & a specialized container for the top category Rouse Cards. Its system was designed to harness the J: "Fusion Peacock" & Q: "Absorb Serpent" Rouse Cards & is only compatible with those cards. Initiating either Jack Form, modifies the Rouser Absorber with a signature diamond-peacock plaque. Though the Rouse Absorber is dubbed Diamond Absorber henceforth, the modification, in either case, proves more cosmetic if anything.

Red Rhombus
The Red Rhombus is a motorbike developed by B.O.A.R.D. specifically designed to the aspects of Diamond Warrior's Rider System.

Fire Rhombus

 * Cards Required: Fire Fly (6)

This performance mode is activated with the use of the 6: "Fire Fly" card. Once 'roused', the Red Rhombus generates a fiery aura which fends against obstacles.
