RWBY x Kamen Rider - Grimm Rider Kiba(Showa/Proto)

Finally done with the concept (minus weapons atm, too lazy to draw them), and even added a base suit so anyone can be a rider :3

    The belt, which I would like too call the Grimm Driver, functions similarly to the KR Ghost's Ghost Driver and the Gaim Riders' Sengoku Drivers. It can transform anyone into an less-armored form first, and requires and item called a Grimm's Eye, which can be obtained from defeating Creatures of Grimm and using an empty eye before their body evaporates (think of Pokemon but mix in some Monster Hunter).

Functionality:
    To use the Grimm Eye on the Grimm Driver, the handle on the left-hand side should be pulled all the way to open the "mouth", which the Grimm Eye is inserted, and the handle pushed back in to close the "mouth", and initiating a standby tune, and transform into the less-armored form. To don the Grimm Armor, one should simply push down the horn on the back of the head and create a "biting" action and opening the eye.

    When in Grimm Armored from, the user can use abilities and weapons from the Grimm's Eye, which is done by doing "bites" on the belt:

1 bite = [Grimm Name] Biting! = Equips the rider with a weapon based on the Grimm (in Kiba's case, its a pair of small spiked and clawed gauntlets, increasing his attacks)
2 bites = [Grimm Name] Chomping! = Uses and ability based on the Grimm for a short time (in Kiba's case, he gains the legs of the Beowolf, giving him increased jumping power and agility)
3 bites = [Grimm Name] Mauling! = Initiates the Finisher, which uses the Biting and Chomping simultaneously, but with deadly results (in Kiba's case, his finisher will be jumping and striking the target with his gauntlets from different directions as he bounces around and finishes it with an overhead claw strike)

    Also, the armor substitutes as Aura for those who have weak Auras or none. But there's a catch, if the user has enough negative emotions, the Grimm Eye will become sentient devour the user from inside the suit, and turn the user into a Creature of Grimm.

RWBY and any related lore belongs to Roosterteeth and the late Monty Oum, rest his spirit.
Kamen Rider belongs to Toei and Shotaro Ishinomori
I own nothing except my life and work.

P.S. if you want, you can use base suit to create your own Grimm, as long as you give me credit. You may modify it as well, because the base suits are not all the same and are unique to the user. Also, as there are only 8 known Creatures of Grimm existing in Canon RWBY-verse the time this pic was uploaded, fan-made Grimm are fine too.
