A Grimm Semblance

Ch.1 A Man, a Wolf, a Bear, a Bird

It was weird how peaceful the Emerald forest was.

When the Grimm weren't running around, it was beautiful.

The leaves were a beautiful green and just enough sunlight poured in, providing enough light to highlight the natural colors.

It was at this moment that Jaune wished he had a camera, to capture this quiet moment.

Or maybe he would try his hand at painting, start a new hobby.

But he was probably going to die.

Lying in the dirt, back against a tree, shield knocked away and barely able to hold onto his sword.

He had thought he had put up a good fight, but apparently the alpha Beowolf thought otherwise.

The Grimm advanced on him slowly, as if expecting a counter attack.

Jaune stared back, not showing an ounce of fear. Planning to hopefully grab it with his left and stall it long enough to get in a stab.

Not because he wasn't afraid, but because he simply couldn't bring himself to care.

It was over for him, even if this worked, something else could come by and finish him.

There was nothing he could do. No point in whining or begging.

This was it, end of story.

"Ya'know, it's funny." Jaune let out a chuckle as the alpha approached. "I saw what happened."

He hadn't stumbled on a pack and fought it. He had seen another team fighting Grimm. Hoping to get a few pointers, he sat down and watched them.

It showed just how far behind he was from his peers, even if these people were upper years.

Mimicking the movements of a swordsman from where he was sitting, he hadn't noticed the Alpha being slung at him by another member of the team. They went for a tumble before they both righted themselves.

Sword drawn and Grimm growling. They entered battle.

And that brought us to here.

"Your… pack was killed." The blond chuckled again as he gestured with his left hand, not sure what the term for a group of beowolves is. "And I lost mine to my own stupidity."

"In a way, I'm just like you." Blue eyes closed as he started to laugh. "A being that brings down huntsmen, who drags them down until they die."

"But, look at the bright side, at least we have each other." Eyes opened to stare down his opponent. "Two lone wolves with nothing to lose."

With that the Grimm lunged and his left hand went up.

He didn't notice the aura covering it.

The moment his palm and the Alpha Beowolf's chest came in contact the world exploded in pain.

Jaune felt the Grimm struggle against his palm, yet something was forcing it against his hand.

Soon the pain started to surge up his arm until it came to focus on the underside of his forearm.

As the pain faded, Jaune managed to open his eyes. Seeing no threat, he slowly turned his arm around and moved his sleeve.

On it was a tattoo of an Alpha Beowolf..

'Is this my semblance?' He asked himself as he removed his glove and sleeve. 'The ability to turn Grimm into tattoos?'

'Kill…'

"What?" Jaune started to look around as he tried to figure out where the voice was coming from.

'Must...kill.'

"Kill...what?"

'Must...kill...you!'

With that his head exploded into pain, causing him to curl in on himself.

Jaune's mouth opened wide as he tried to scream, yet all that came out was a line of drool. He curled into a ball as he felt something ravage his skull.

He had no idea what the hell was going on, but he knew he wanted the pain to stop.

But he didn't want to die.

So he fought, fought against the pressure in his skull, forcing it back with everything he had.

Whether it was a minute or an hour, the pain started to recede.

Slowly making his way back to his feet, he brought a hand to his head again.

'The hell just happened?' He asked himself as his other hand grasped at the tree behind him.

'What...happened?'

"Hello," Jaune started to look around as he heard the voice again. "Is anyone there?"

'I...Beowolf.'

"What?" Blue eyes widened in shock after a moment. "Are you in danger from a Grimm?"

'Am a...Beowolf.'

"Wait, what do you mean?"

"I am a Beowolf!"

With that the tattoo on his wrist started to glow as something shot out of it.

Landing in front of him was a shadow that started to take shape.

As it settled into shape it stood before him.

An Alpha Beowolf.

They both stared at each other. Neither moving or speaking at all.

"Uhh, hi." Jaunt gave a little wave at the Grimm that was once part of him.

"H-hello." The Beowolf replied.

They continued to stare.

"Did you just talk?" Jaune asked as he took a step forward, towards a beast that he should be slaying.

"I did." The Beowolf started to look down at itself in what Jaune thought to be awe. "I can feel, I can think."

"Did I do this?" The blonde mumbled to himself, causing the beast of darkness to look up at him.

"You did." The Beowolf looked at him, head tilted to the side.

"How?" Jaune wasn't expecting an answer, but he got one.

"When we merged, our consciousness fought for dominance." The Beowolf explained. "When yours had won, it seemed to impart some of your power into me. Thus giving me sentience."

Jaune looked at his left arm in thought.

"So I basically beat you in a battle of wills, gave you some of my aura, and that makes you smarter." Jaune summed up.

"As far as I know." The Grimm seemed to shrug. "I am basing this on my experience and what you know."

"This is…" Jaune was at a loss for words.

"Amazing." They both spoke at the same time. The blonde look at the Grimm as he raised his hand towards it. Lightly touching the white bone that shaped its head.

When his fingers came into contact, the bone started to crack. Pulling his hand away, Jaune watched in fascination as the Grimm started to transform.

Watching as it fell onto all fours, it's body started to shift and take on a lighter color. As if made of clay, it's body moulded until it looked like an actual wolf with a white coat.

"Did...I do that?" Jaune looked away as he tried to hide his embarrassment. "Sorry if I hurt you."

"No, It didn't hurt." The wolf replied as he seemed to pause for a second. "It's just…"

Within seconds he transformed again, back into his original form.

"I believe my aura has given me the ability to change shape." He flexed his claws and turned to Jaune. "But it seems I can only change into a wolf."

"Huh. Weird." Jaune replied. "Must be your semblance."

It made as much sense as anything that happened in the last couple of minutes, all things considered.

But still this was amazing, with this he could learn how to fight Grimm from the very best teacher.

The Grimm themselves.

"Soooo…" Jaune lightly scratched the of his head as he tried to broach the topic.

How does one ask how to kill another's race? Without looking like a complete dick.

"You have questions about me and Grimm." It was less of a question and more of a statement. "I will answer to the best of my abilities."

"Thanks."

"In exchange, I will ask questions in return."

"Seems fair." Holding out his hand to the Beowolf, the Grimm looked at it curiously.

"It's a hand shake." The blond explained as he took hold of the grimes arm and took it's claw into his palm. "It's a way of saying that we will follow through with what we promised."

The Grimm lightly moved his claw up and down, careful not to hurt the human that gave him this chance.

"First things first." Jaune pointed to himself. "My name is Jaune."

"I'm afraid I do not have a name." The Beowolf replied. "How does one get one?"

"A parent usually gives you it."

"I see." Silent for a few seconds the Beowolf gestured to the huntsman in training. "Will you give me one?"

Jaune felt himself pull back slightly at the request, sliding down the tree against his back until he was in a sitting position.

"I do not have a "parent" as you say." The Beowolf explained, awkwardly sitting down next to the blond. "You have given me the understanding that I needed for a name, so I ask you to give me one."

It made sense, to Jaune at least. From what everyone knew, Grimm were just mindless beasts that's only real intelligence came from age. And even that was mostly tactical.

"A name…" The blue eyed knight looked around in an attempt to come up with something. He thought about the type of Grimm next to him, when a thought occurred.

"Rex." Overused as it was, he felt it was something that fit. "I heard it means king in another language."

"Rex." The Beowolf tried it out, letting it roll around as in his mind. "Yes, I like it."

"Then, nice to meet you, Rex."

"Likewise, Jaune."

With that boy and beast began to talk, learning about the differences between them.

The boy had told the Grimm about hunters and his family. How they used dust to help them fight and the different kingdoms.

He told Rex about his own life, how he had cheated his way in to Beacon and how his friends were giving him the cold shoulder over it. How his family never believed in him, how he almost didn't believe in him.

The Grimm just sat and listened.

When Jaune had finished, he felt better than he had in days. Just getting it out of his mind had felt like a huge weight had been lifted off his chest.

The Grimm did not move for several seconds, letting the boy breath.

And then started to talk about his story.

The blond listened in fascination as the Beowolf talked. Taking all that was being said.

From the explanation of how he simply existed before today, how he and all Grimm were spawned from black pits of liquid.

But what caught his attention was the name Salem.

From what Rex had told him, she was the leader of all Grimm. He had never truly seen her appearance, but he had always felt her presence in his mind.

Until Jaune severed that connection.

Blue eyes stared at the Grimm in a way that could only be described as "aw shit."

He literally went from the most uninformed huntsman to one of, if not the only one, to know about the Grimm this way.

And he couldn't tell anyone without looking nuts.

'My life is a roller coaster.' He thought, staring at nothing with a blank look on his face. 'It's in a downward spiral, going so fast I'm surprised my spine is still in my body.'

Seeing a claw in his vision, he snapped back to Rex, who seemed to have a concerned look on his face.

Well, as concerned as a creature of darkness could be.

"We have company." Jerking his head up Jaune noticed several more beowolves entering the clearing.

And they did not look friendly.

"Ohh boy." Standing up, the blond had felt his aura and body had recovered. Bringing up his sword, he prepared for battle.

When the first Beowolf jumped at him, he pulled back to slash it. Until it was tackled by Rex.

Watching the good Beowolf plunge his claws into the bad Beowolf, Rex seemed to curse as he ripped out his claws.

"As I suspected." Jumping back, Rex turned to Jaune as the other Grimm got up. "Grimm can not kill Grimm, you must land the final blow."

"Okay, I can do that." Pulling his sword above his head, he drove the blade into the Grimm.

Pulling away he and Rex went back to back as more Beowolves approached.

"You're in no shape to fight." The Grimm told him. "So I'll damage, you finish them off."

"Right."

With that, for the first time, man and Grimm worked as one.

The white blade hacked and slashed as the Beowolf created openings for him. They worked together as the Grimm fell one after another.

As the last one fell, Jaune propped himself up with his sword, breathing heavily as Rex walked next to him.

"That seems to be the last of them." The Beowolf lightly placed his hands on Jaune, helping him stand.

"Awesome." letting out a final huff, the blond pulled his sword from the ground.

Just in time for an Ursa Major to charge at them.

"Ohh, come one." Picking up his sword, Jaune had an idea as he glanced at his hand.

"Rex, hurt it as much as you can." The knight flexed his left hand as the Beowolf looked at him. "I'm gonna get you a new playmate."

"I see." The smaller Grimm rushed the larger one, swiping with his claws as he danced around it.

Jaune joined in, stabbing its arms and legs, careful not to hit anything he deemed vital.

With a simultaneous slash of both claws and sword, the large Grimm fell.

Hopping onto its back, Jaune had a bright smile as he charged aura to his hand.

"Here goes nothing!" With that he slammed his hand under the Grimm's mask.

The results were instantaneous, Jaune's aura over took the Ursa and pulled it into him. Knowing what was to come next, he steeled himself for the confrontation.

It hit him like a train.

Falling to his knees he gripped his head, Feeling the pressure against the inside of his skull.

Unlike with Rex, who seemed to claw any way he could, the Ursa just pounded on one spot.

Still, he would not lose to an overgrown, walking rug.

And so he pushed back, with everything he had.

In the end, it was enough.

Feeling it focus on his bicep, he rolled up the other sleeve. Looking at the new tattoo, he smirked as it leapt off his body and took form.

"Hello and welcome." Jaune held out a hand to the bear like creature. "To the first day of consciousness."

"G'day guv." The Ursa replied as he took the blond's hand. "How're you?"

The knight stared at the Ursa then turned to Rex, a question on both their minds.

'Why does he have an accent?'

"Fine, thanks." Pulling his hand back, Jaune scratched the back of his head. "Uhh, you're probably wondering what's going on."

"Nahh, guv." The large Grimm shrugged. "When I got some aura, I knew what had happened."

Letting out a small hum of thought, Jaune turned back to Rex.

'Rex seemed to know everything about a language that he didn't speak.' Tilting his head, He raised a hand to his chin. 'Could it be they know everything I know?'

It made sense, to him at least, they were a part of him for a brief moment.

'Ehh, whatever.' He figured. 'Just makes my life easier.'

He was interrupted as a Nevermore fired a feather spear into the ground in front of him. Looking up towards the Grimm that started to circle around them, he held up a hand to block the sun to get a better look.

'A bit smaller than the one Ruby and them fought.' Pulling his hand back, Jaune smiled as he looked towards the Beowolf.

"Rex," He looked towards the Ursa. "Beast." He pointed at the Nevermore with his sword. "Three for three?"

The Beowolf flexed his claws as the Ursa slammed his fist into his open hand.

Grimm semblance

Strolling into Beacon in a good mood, Jaune flexed his left arm and felt the bones pop. Looking down at the sleeves that hid his new additions, he couldn't help but start whistling as he walked.

With a hop in his step, he made his way to his dorm, wanting to grab a quick shower before he went to dinner.

Seeing Cardin and his team on the way, who gave him a mocking wave. He casually waved back with a single finger.

Seeing Cardin's face reddened with anger was a beautiful sight to the blond.

'Even if he leaks my transcripts, so what?' Jaune smiled as he threw the doors open and walked into the dorms. 'With my seblance, the entire world will want my attention.'

Finding his way up to his dorm, he casually opened the door. Closing it behind him, he stopped when he saw his partner.

"Jaune, you're back." Pyrrha noticed him as the door closed. Standing up from her bed, the red haired champion glanced at her partner, who was looking at her in… annoyance?

"Oh, hey Pyrrha." Walking to his stuff, he pulled out some fresh clothes. "Ren and Nora at dinner?"

"Yes, they went ahead. I decided to wait for you." Green eyes looked away for a moment. "Jaune about what you told me before, I..."

She was cut off as the door to the bathroom shut with a loud click. Hearing the shower start to run, she shook her head clear.

'What was that?` Pyrrha asked herself as she stared at the door. She had never seen Jaune so dismissive of anyone. Even when he had confessed about his transcripts, he had angrly acknowledged her.

Now it was like he barely noticed her.

'Maybe I need to give him more time.' After all, he had never really been angry at anyone that she had seen. Maybe he was type to nurse a grudge for a long time? She didn't know.

On the other side of the door, Jaune had turned on the water, but had not stepped under the spray.

'Why did I do that?' He asked himself as the water grew hotter, yet he did not move to it. 'I'll admit we're not on the best terms, but I've never been that cold.'

'That's because you know your place compared to her.' The newest addition spoke up. 'It's only natural that you would be annoyed by lesser beings.'

'Okay, Soar, no.' Jaune had no idea why, but for some reason the Nevermore was perhaps the most arrogant thing he had met.

It probably had to do with the fact that he could fly. He could also shoot feathers, which was cool.

'Perhaps your emotions are being affected by us.' Rex spoke up, causing Jaune to frown thoughtfully.

'Possible.' Finally deciding that he wasted enough time. He stepped into the shower. Scrubbing off and ignoring his Grimm's comments, he threw on his stuff and made his way to dinner.

Stopping before the cafeteria, the blond paused to make sure his sleeves were coving his new tattoos. After double checking everything, he opened the doors as nonchalantly as possible. Keeping himself to the other side of the hall then his team and RWBY.

Out of the corner of his eye, he saw Yang and Ruby happily chatting, Nora telling a story to Ren, Blake reading while Pyrrha and Weiss were discussing something. Seeing a chance, he walked to the end and grabbed a tray and food.

Keeping his back to his friends, he sat at a table near the end. Staring at the window, he ate as his Grimm conversed in his mind.

He mostly tuned it out, considering they were mostly talking about literally anything they saw.

Just as he was finishing up, a commotion caught his attention.

Cardin was pulling the ear of the rabbit fanus. Jaune couldn't remember her name, but it reminded him of cake, for some odd reason.

He was about to get up and intervene, when Rex cut through his thoughts.

'Are you planning to help?' The Beowolf asked, his tone seemingly disappointed.

'I'm thinking about it, yes.'

'Why?' Soar was the one who spoke this time. 'Is she not a huntress?'

'Well, yeah…'

'Then she should be fully capable of standing up for herself.' Rex continued. 'If she cannot stand up to schoolyard bullying, how can she stand up to Grimm?'

That gave the blond pause. Although he had not seen the girl fight, he had assumed she was strong if she had managed to survive to become an upper year.

So why wasn't she fighting back against Cardin?

'The teachers weren't stopping it.' He thought as his eyes strayed to the staff table. 'Maybe they won't unless there's actual violence.'

And even if the staff won't interfere, where was her team?

He supposed it could have been a bit of a test, get her to stand up for herself.

But it was obvious it wasn't working.

So if she wasn't going to stand up for herself and no one else is going to stand up for her, should he?

And surprisingly, he decided no, he didn't.

He had his own problems with Cardin's bullying, though it was going to end.

The biggest problem he had was that if he did do something, odds are his semblance would come out.

And summoning Grimm in the middle of a room full of Grimm slayers in training would probably end badly for him.

So, despite wanting to help, he figured it'd be best to not to draw attention to himself.

At least until he could use his Grimm and not end up with his head on a stick.

He gave one last glance back at Cardin, before opening the doors and heading out.

His time would come, sooner or later.

Grimm semblance

Jaune was up bright and early the next day.

After he had returned to the dorm, he had just managed to get on his onesie before his team returned. Which he was thankful for considering the sleeves.

And the fact that it was awesome. And anybody who said otherwise obviously didn't know the feeling of wearing something comfortable that was made by a little sister.

Okay, so his older sister did most of the work, but his little sister was the one who had the idea. So it totally counted.

Changing in the bathroom, he quietly made his way out the dorm after grabbing some text books. Moving to the kitchen, he grabbed as much food as he could carry and put it in a bag.

With his weapon, food, books and Grimm. He went back to the Emerald Forest to spend the day training.

Which was going pretty well, in his opinion.

While he didn't really fight them, he and his Grimm tried to figure out the limit to his seblance.

And he found out a whole lot.

Sitting down with his notes. The blond looked over his list.

The first part was everything he already knew about. Such as the absorption and stuff.

The next was hypothetical, which came with a mixed bag, but still good. Such as Grimm semblance and distance.

The last was just general notes as he learned. Like the fact his Grimm could eat and regain aura as soon as they swallowed.

Feeling something coming, Jaune casually grabbed his sword and ran the Beowolf that Beast was holding through. When it vanished, he laid the sword down next to him and threw Beast a slice of meat.

They all liked meat, for some reason.

Reaching up to give Soar, who was beak first in a book on dust, a quick pet. He grabbed his pencil and started to write again.

"Jaune, you and Rex have been like that for half an hour." Soar complained as he jumped down onto Jaune's arm. "I wanna see what we can do."

"Probably a good idea." The black haired blond agreed. Feeling Rex pull from his body, his enhanced sense of smell went back to normal as the marks and black once pulled away to become his Beowolf.

The feeling of a Grimm entering and leaving his body like that was so strange. With them just being tattoos, he can feel them on that part of his body.

But when he and they actually merged, it was a whole other experience.

His body changed, yet he felt like the changes were something he had his entire life.

Like when he and Beast were one, his muscle gained a huge amount of mass.

With Rex, his sense of smell grew sharper as bone like claws extended from his fingers.

Now to see what he had with Soar.

Jaune pushed himself off the ground as he looked behind him in awe as he raised his hoodie.

A pair of blackish blue wings sprouted out of his uncovered back.

Somehow managing to move them in front of his face, he lightly ran his hand over one.

"Soar." He said out loud. "I'm going to have so much fun with this."

With that he flapped the wings towards a tree in front of him, smiling wide as feathers embedded themselves into it.

Next he wanted to see if he could actually fly.

But he figured he should at least read up about how it would work instead of just jumping off a cliff.

No Pyrrha around to pin him by the hoodie if it didn't work.

On the senses side of things, his eyes could perceive things way better.

Yep, things were looking up for Jaune Arc.

But of course, there was always more to find.

Like more Grimm.

After all, the three he had were only the start.

By the end of his four years here, he'd have one of every type.

And then he'd take the fight to Salem.
