Grimm Rider: Chapter One

A/N: Welcome to my second piece of fan fiction, a crossover between RWBY and elements of Kamen Rider. For those wondering about my other fic, I'm still writing up the next chapter I just have a real lack of focus for how I want the plot to go. This was also floating around in my mind for awhile, so writing this down might just help organize my thoughts.


He woke up in a green forest.

Slowly picking himself up, he gazed around at the unknown location around him. A horrid pain shot through his head as he tried to remember what he was doing here. All he remembered was tubes, being on an operating table, and a location. A ruined temple stuck out in his mind but not even his own name. His legs slowly moved him through the forest, leading him as if on autopilot.

A camera whirled to life as it detected movement, sending a digital alert to a certain headmaster.


Ozpin was rarely awake at such times, he understood the importance of a good night's rest. That understanding was the reason why he was confused that anybody would be travelling through the Emerald Forest at the dead of night. His students, for the most part, would stay in the dorms around this time as many of Beacon's facilities were closed and the bullheads were all shutdown until morning. Switching views to a camera that was closer to the ground, Ozpin quickly concluded that this person was clearly not someone of Beacon Academy.

The boy's outfit could hardly be considered clothes, they looked more like a hospital gown. He stumbled through the forest in one direction, right towards the temple that was used to house the chess pieces at the beginning of the year. Ozpin doubted that without rescue the boy's chances of survival were slim, even if the majority of highly dangerous Grimm in the area were killed by the students during Initiation.

Ozpin simply sighed before looking at Glynda, whose eyebrows were furrowed in confusion much like his own at the situation.

"Gather team RWBY."


His legs had seemingly carried him to the temple from his memory. Walking up the steps, he looked around at the several pedestals but they were not important to him. The boy felt around the circular stone placed in the center of the temple. He found a spot that allowed him to get a grip and lift it up, revealing a hollowed out area with items inside it.

Grabbing the first item, he realized it was some kind of belt buckle. It was almost pitch black besides for the face plate being a pearly white, a clear glass circle in the center showed small machine parts within. A medium sized hole was placed on the right side and two buttons jutted from the top.

The second item was a large satchel. Inside contained weird looking syringes, all were empty except for one. This syringe contained a black liquid sloshing around within, a small panel above the looking glass had a logo on it depicting a side profile shot of a black wolf with a white mask.

The boy was interrupted from his inspection as a loud roar cut through the silence of the forest. Turning around revealed three grimm surrounded the temple's entrance. He backed up a step before he placed the belt buckle around his waist. A black belt formed and circled around him, keeping the device securely in place. Grabbing the full syringe, he inserted it into the open hole in the driver. The plunger popped up as the syringe clicked into place.

"DNA MUTATION." A mechanical voice sounded from the driver. He pushed the plunger down. "BEOWOLF." The fluid inside the syringe filled the hollow space within the driver, the same logo from the syringe appearing in the glass.

A pool of black liquid formed at his feet which quickly climbed up his legs and encased his entire body. A holographic screen passed over the black mass, causing it to solidify and take shape in the form of armor. His chest and back was covered in thin pearly white armor plating. Similar armor was placed in front of his forearms, shoulders, kneecaps, legs and feet. His helmet was black except for a white face plate, topped off with bright red eyes. Small white spikes jutted out from the side of his forearms, curving upwards. Underneath his armor was a pure black under-suit. On the armor plating placed on his back was four vents, two located on each shoulder blade.

Silently, he pressed the right button on the driver. A cone of light shot out the front before taking the shape of a two-handed axe, a long axe head adorned the top. Grabbing his weapon he slowly approached the three Beowolfs.

The one closest lunged through the air at him, thinking of him as some weak prey. Instead, it got swatted away by a swing of his axe on the blunt side. It landed somewhere in the dark underbrush. The second one charged straight at him, cause that worked so well for the other one. Handling the axe with surprising agility, he thrusted it forward to stagger the grimm before delivering two quick diagonal slashes across it's chest. He gave a overhead swing into it's head, breaking the bone armor and killing the monster.

The third Beowolf leaped at him much like the first one, but with the added advantage of having his back turned to it. Quickly dislodging the axe, the boy clicked a button in the middle of the handle. The handle of the axe shortened to half it's length before it bent in half, a trigger popping out from inside. The bladed edge retreated inside of the axe head allowing him to grip it without harm. The grimm fell on him, both falling to the ground in a heap. The barrel of the axe-turned-gun was in-between them placed facing towards the Beowolf's chest. The beast scratched uselessly against his armor.

He pulled the trigger and the grimm's chest violently exploded, spreading it's blackened blood across the grass and trees. The dead grimm slowly dissipated as he shrugged it off him. Getting up, the first Beowolf had burst through the forest and tackled the boy. The axe was thrown in a random direction as he lost his grip in surprise. A quick punch to the head threw the monster off him and allowed him to get some space.

The two similar looking beings stared at each other, one gave an animalistic glare, the other's mask betrayed nothing to what he thought. He popped the plunger outwards before slamming it back in again.

"INJECTION. BEOWOLF KICK." He sprinted at the Beowolf before leaping up high into the air. The vents on his back opened up and shot streams of fire out, propelling him higher. Black swirling mass encased his leg as he was flying forward . The Beowolf didn't have time to dodge as his foot smashed into it's chest, sending it flying into the forest out of his sight. A distant explosion sounded before the silence returned.

The young man stood still, releasing a breath. He stared down at himself in wonder. How did he know how to fight like that? Scratch that, how did he even know about the driver in the first place?

A bullet ripped through the air and impacted his shoulder. He grabbed the injured joint as a dull pain ran through it.

Turning around, four women were intensely staring him down. He threw up his hands to protect his face as the red and black colored girls fired a storm of bullets at him. In his exhaustion, he didn't notice the ice trail worming its way on the ground until it encased his legs. The blonde woman fired a shot behind her and launched at him with surprising speed, slamming her gauntlets into his chest. The ice shattered as he was launched through multiple trees. He could feel his armor dissipate as the driver unhooked itself from his waist, launching deeper into the forest as he impacted a final tree and bounced off.

Before he blacked out he slowly crawled towards his axe that layed a few feet away from him. Darkness overtook his vision as he grasped the handle.


Grimm Rider Chapter One: End.

A/N: For anyone who wants a clearer image of what the suit is like. I based it, and the axe, off of Chaser. It could just be that I've been watching Drive lately and haven't finished it, but I do really like Chaser's suit design. The syringe's on the other hand are based off the ones of Amazons Season two.

Also, I'm uploading this at 4:30 AM so if I did screw up some wording and/or grammar be sure to let me know. I probably missed it in my tired state.
