A/N- Thought this might be a good concept for a crossover. Tell me what you think. Should he still be a bad guy, or have a change of heart and be helpful. Not sure if I will do much with this unless someone else wants to take the premise and run with it.

Chapter 1

"It shall begin soon... Darkness will pour forth from the doors of hell... a darkness to swallow all the worlds light."

In a forest clearing lay a man. Or rather, a monster with the strapping's of a man.

The monster wore a long, black jacket trimmed with a light-colored flame pattern; the lapels are a matching lighter color as well. The cuffs of his jacket are rolled up, revealing a light-colored inside, which contrasts the black outside of his jacket, and have a black line cutting through the edge of the fabric. Beneath the jacket he wore a frilly dark v-necked shirt. His black pants hung lazily over his equally dark boots.

The monster himself was tall, lean, and had the appearance of a young man. His black hair is long and wavy, reaching his shoulders even whilst the majority is tied up in a very large ponytail. Additionally, his messy bangs all but obscure his dark, slanted eyes.

Suddenly the being's eyes snapped open and he began to sit up.

He examined his surroundings with a mildly confused look, but maintained composure on his face.

"What is going on?" he asked aloud, more to himself than anyone who might be within earshot, which from the looks of it was nobody.

"What happened?"

The monster suddenly grabbed his head in pain as his mind was assaulted by memories.

Two humans. One with salmon pink hair and another with hair as dark as the night. They foolishly stood against him, but despite all odds they came out victorious. His plans foiled, his guild in ruins, and in his final moments... his master cast him aside.

"Mard Geer... can fulfill... your wish..." he rasped out as he reached towards the black eyed man.

"That will no longer be necessary." the man said as he snapped his fingers.

And then... nothingness.

His entire world went blank and the next thing he knew he had woken up in this forest.

Mard Geer examined his surroundings in a futile attempt to figure out where he was, but as far as he could tell he was in a forest somewhere. It was dark out for what it was worth so it made things harder to see, although his eyes were rapidly adjusting to the darkness.

One thing he took note of was the absence of ethernanos in the air.

"Did Face go off after all? No, impossible. The dragons destroyed it. But why the lack of ethernanos then?" he thought aloud as he pursed his lips and brought his hand to his chin.

"Perhaps Mard Geer should find out where he... is..." his voice trailed off at the end as he cast his eyes towards the sky where he noticed something out of the ordinary. The moon was shattered like a broken mirror.

"Perhaps this one is no longer on Earthland."

Suddenly a rustling was heard in some nearby bushes. Mard Geer turned his attention to the sound and as he did a large beast emerged from the foliage.

It had fur of the purest black and glowing red eyes that were filled with malice. Upon its head was a mask of bone, white as the moon itself with intricate patterns scrawled across it. Stuck in the beasts back were several spikes that were jutting out from its flesh, but they did not seem to cause it pain. It had razor sharp claws that appeared to be made of the same material as its mask. The overall figure was that of a bipedal wolf, quite unlike any creature Mard Geer had seen before.

The beast reared up on its hind legs before arching its head towards the sky. Then, without warning, it howled. The howl echoed throughout the forest and without a doubt was meant to call attention to its position.

Mard Geer cocked his head to the side for a moment as he pondered what was happening. He could tell just from a glance that this creature was hostile given the predatory look it was giving him, but he was unconcerned with the threat it posed as Mard Geer was vastly superior in strength.

"Hmm, you think that you are worthy to stand against Mard Geer?" he questioned the beast who simply charged at him in response.

Mard Geer raised his fingers up in the direction of the creature.

"Pathetic."

At his utterance, several thorny vines erupted from the ground and impaled the body of the beast. It was struck twice in its torso, once in its leg, and again in its head, killing it instantly.

Mard Geer then dispelled the vines, allowing the body to fall to the ground where it started to rapidly decompose. Just in time for several more similar creatures to jump out from the treeline.

"Hmmph, you must be awfully full of yourselves if you think that you even stand a chance against Mard Geer."

Mard Geer held up his hand and in it grew several roses. He then threw the roses at the creatures like knives whereupon they embedded into the creatures skin. Moments later the roses exploded, blowing apart the beasts bodies and sending blood and viscera everywhere.

"Completely pointless. Though Mard Geer must admit that he is curious as to just what these beasts are. Perhaps he should start with trying to find out just where he is." Mard Geer spoke rather eloquently as he promptly headed into the forest.

Mard Geer walked through the forest at his own pace, not caring about any of the potential dangers that lurked in the shadows. While he walked he had time to ponder his current situation.

"Just what exactly happened after Mard Geer failed? Did master send him to this world as punishment? Or was that an unforeseen consequence? Hmm, for now Mard Geer will do his best to find out where he is, then he will worry about figuring out what to do next."

After a few hours of walking through the dark, Mard Geer began to see a light piercing through the darkness.

"Ah, finally, some progress."

As Mard Geer made his way towards the light he began to see tents through the trees, and with them humans.

"Tch, detestable creatures." Mard Geer said as he lightly ground his teeth, remembering how his guild was brought low by such creatures. Under normal circumstances he would happily slaughter any human he came across, but right now with no idea where he was and with out a clear goal, he decided to play nice. So Mard Geer put on his usual grin and approached the camp.

When he made it into the clearing he noticed that all of the humans were wearing uniforms of some sort. Black and white hooded jackets with white masks similar to that of the beasts he fought earlier. He found it strange that some of them had antlers or animal ears poking of from their hoods, but decided not to dwell on that. He did notice however, that scattered about the camp were various firearms and swords. Clearly this was not a simple camping trip, but Mard Geer cared not for the danger that was presented.

Seeing as how no one had yet to notice him, Mard Geer walked up to an unsuspecting man and tapped him on the shoulder.

"Excuse me."

The man spun around and immediately stumbled backwards upon seeing Mard Geer.

"Would you be so kind as to tell Mard Geer where he is?"

"INTRUDER!" the man shouted in response which called attention to Mard Geer's position.

In the span of several seconds every person in the area had grabbed a weapon and surrounded Mard Geer.

Mard Geer couldn't help but let out a chuckle at the situation. Of course this was how they would react, but Mard Geer was far from worried. In fact, it was the humans who should be worried right now.

"Mard Geer thinks that it is quite rude to be pointing weapons at someone asking for help."

"Somebody go get Taurus!" one of the gun toting men shouted. Another ran off in response to him.

Mard geer remained still as the humans got progressively more edgy. He was doing his best to hold back the urge to kill them all right then and there, but he needed information and right now they were his best bet.

After a few moments of contemplating his options, Mard Geer noticed someone new approaching. The man wore a black jacket over a red shirt, had red hair with two horns sprouting from the front of his head, had a white visor covering his eyes, and strapped at his waist in an unusual sheath was a katana.

The man walked forward into the ring of guards that surrounded Mard Geer and stood mere feet away from him.

"Who the hell are you?" the man ground out.

Mard Geer let an arrogant smile creep across his lips.

"I have gone by many names. The Underworld King, master of Tartaros, the crimson thorn, but you may refer to me... as Mard Geer."

"What kind of ridiculous name is that?" Taurus asked.

"One that you will remember in hell." Mard Geer replied ominously. All of the grunts tensed up at the remark.

"But I digress. That will have to wait for another time. Right now Mard Geer is in need of information. Would you be so kind as to tell me where I am?"

Taurus drew his sword and pointed it at Mard Geer, inches from his face. "Why the hell should we tell you anything? You're just a fithy human." he snarled.

"While my outward appearance is as such, I can testify that I am far from human." Mard Geer stated before adopting a curious look. "Still, are you not human yourself?"

"We are faunus you bastard! We are not on the same level as you trash." Taurus spat out with disgust.

"Hmm, curious. Mard Geer fails to note the difference between you and humans. Is it the animal ears?"

"Are you some kind of comedian? Or are you just plain stupid? Have you really never seen a faunus before?"

"I suppose I haven't as I am not from here. But in my eyes you are essentially the same as human aside from your animal traits."

"Don't you dare compare us to them!" Taurus barked.

"If I had to make a comparison, it would be like comparing insects to arachnids. Sure they are different, but because they are so similar one fails to take note of the differences. That is how Mard Geer views humans. So, in the end I still can't see you as anything more than a human."

"You bastard!" one of the more hot-headed grunts screamed out in rage as he charged Mard Geer with his sword. He never got far.

Mard Geer turned to the man, a sinister look plastered on his face, and lazily pointed his fingers towards the foolish man. As he pointed, a vine of thorns shot up from the ground and pierced the mans chest, right through his heart. He had no time to react, no time to feel pain, no time to be shocked at the fact that he was about to die. Nothing, just instant death.

The vine remained in place, holding the mans lifeless body in place which unnerved the remaining faunus.

"As you can see, acts of aggression towards me are a most foolish endeavor. So it would be in your best interest to comply with my request as it is the best course of action to extend your already shortening lifespans." Mard Geer spoke rather eloquently as he returned his attention back to Taurus.

Adam Taurus had no idea what to think right now. Just who on Remnant was the man who was standing before him. He came out of nowhere, seemed to have no idea what a faunus was, and just killed one of his men instantly.

He pierced right through his Aura like it was nothing. Was that his Semblance? Adam thought cautiously as he steadied his blade.

Plus there is also the unnatural 'aura' he himself gives off. It just feels wrong.

"So I will ask again, where am I?" Mard Geer asked.

Adam, deciding it would be best to at least wait until the man lowered his guard, chose to comply with the mans request.

"You are currently in the White Fang camp on the outskirts of the Kingdom of Vale which is a few miles to the north."

"Ah, I am afraid that I have never heard of such a place. It is as I feared. Master has sent Mard Geer to another world." Mard Geer cast his eyes skyward in a contemplative look. "But for what reason have I been sent here? Without master I am without purpose. Perhaps it is time for Mard Geer to find a new goal in life."

"What the hell are you rambling about?" questioned Adam.

Mard Geer waved his hand dismissively. "Nothing for an insect such as yourself to be concerned with."

Great. First that Cinder woman returns and levels my old camp and now I'm dealing with some kind of loon. Albeit a dangerous one at that. Adam thought as he began strategizing. "Is that all you wanted?"

Mard Geer returned his attention to Adam. "Ah, forgive me, Mard Geer was lost in thought. Just contemplating his next move. But as for your question, I suppose there is something else I want from you."

Adam arched an eyebrow. "And that would be?"

A wicked grin worked its way across Mard Geer's face. "Why, your life of course."

Mard Geer raised his hand and Adam jumped backwards. Just in time too as dozens of vines erupted from the ground around Mard Geer and sent the rest of the White Fang flying as they swatted about.

"Hmm, it appears that you have good reflexes... for a human." Mard Geer finished in a dark tone.

"I'm a faunus damnit!" Adam roared in response.

"And I thought I said that the difference does not matter to me. Human, faunus, all who stand in my way will die." Mard Geer said as he cast his arms outward and smiled. "You will just be another in a long line of many, another body on the pile as it were. But fear not mister Taurus. Since you were so kind as to answer my questions, I will make your death as painless as possible. Do your best to hold still."
