Just something I designed up for my D&D group to look at to give an idea of what my and  noodlepanda's custom Kamen Rider characters use to transform.

The Bahamut Driver is wielded by Raizo Kuwabara and Hayate Nowaki, also known as Kamen Riders Draco and Wyvern. The Bahamut Driver is given to a select few as an object of great power, created to counteract a similar driver created by Tiamat. Visually, I was trying to invoke the OOO Driver with a small hint of the Genesis Driver.

The way the Bahamut Driver is used is simple. When the belt is placed onto one's waist, the user then presses their finger onto the Emblem on the back of the Dragon Claw, causing the claws to unfold into the active form seen here. Once folded out, the user places a Metallic Dragon Scale into the Scale Slot, Finally, the Dragon Claw is pulled quickly across the Scale, causing the claws to scratch across it and draw out the scale's latent magical power, creating an undersuit of scales and armor modeled around the type of dragon whose scale was used to activate the driver.

Raizo uses the Bronze Scale to become Kamen Rider Draco, the dragon of lightning, while Hayate uses the Steel Scale to become Kamen Rider Wyvern, the dragon of wind. They also eventually come into possession of additional scales to add to their powers.

The Bahamut Driver was created by me because I could.
