Kamen Rider Heart Warrior

Kamen Rider Heart Warrior is a Rider who appears in the fanfictional series Kamen Rider: Spade Warrior.

Dirk
Dirk is a mysterious young man who has a connection with the Joker Undead, the most feared of the Undead as his victory in the Battle Fight will mark the end of all life on Earth. Not long after the Undead are released, Dirk battles the Mantis Undead & uses the sealed Category Ace of Hearts (Change Mantis) to become the wild card Kamen Rider Heart Warrior.

Heart Rouzer
The Heart Rouzer is a unique transformation device bestowed upon Dirk. The full extent of its power is unknown, but the Heart Rouzer is capable of reproducing the DNA of sealed Undead & mimic their forms with frightening accuracy, as well as their respective powers & abilities. Further adding to its uniqueness, is that the Heart Rouzer utilizes the "Swipe" function, which becomes the template for the Rider System's "Rouzer" technology.

This Rouzer can be removed from the belt used as a "brass knuckle" sort of weapon to enhances punches or be inserted into the Heart Arrow to use it to scan Rouze Cards without transforming into the Undead.

Heart Arrow
The Heart Arrow is Heart Warrior's weapon & Rouzer, & functions as a multipurpose weapon. Simply put, it is composed of a bow with the curved ends of the bow as sharp as blades. This weapon is capable of shooting projectiles, as well as engage opponents up close using the bladed ends of the bow. The bow can also fold up, turning the Rouzer into a brass knuckle for stronger punches. By inserting the Heart Rouzer into the bow, the Arrow can serve as the Rouzer for Heart Warrior, activating Rouze cards without turning Heart Warrior into an Undead.

Wild Slasher
The Wild Slasher is a peripheral weapon attached to the Heart Arrow when Heart Warrior assumes Wild Form. Two of these are carried by Wild Heart Warrior. A Wild Slasher is a crescent moon dagger which has only half of the dagger as a blade. These daggers are wielded like sickles.
