Team RWBY ran through Emerald forest shooting down every grimm that they saw. But they were chasing a specific grimm. A demon class Grimm.

The team even though are supposed to hunt it are being hunted themselves. The beast roared behind them as Ruby pulled out her scroll and quickly looked for Y/ns number before calling him. But the call went straight to voicemail. "Y/n we need your help. I messed up. I picked a harder mission than what we needed. Please we need you!" She said as the team stopped and now getting a better view of the team they were injured and their aura low with cuts,scratched and even burn marks. Their weapons were broken and their ammo was low.

"Well did he pick up?" Yang asked her little sister.

"No. He must be doing something."

Meanwhile.

Y/n is seen playing games as Carnage was watching videos on his scroll. The image of Ruby appeared on its screen indicating a call. But the symbiote let it go to voicemail before returning to his video.

Back to RWBY

"Next time I pick the mission." Weiss said as the team began to run again.

The Grimm behind them was getting closer and closer as they all were getting exhausted.

At beacon.

Y/n is seen ripping off his medical equipment as Carnage helped him but Atlus military entered the room to sedate them with an electrical shock but Carnage had none of it and grabbed the remote before crushing it. Acting like legs the symbiote used four tendrils to help Y/n move down the hallway quicker towards the forest.  Ozpin watched as Y/n left the school as he took a sip of his coffee. He heard their deal and wanted to see if they truly are in an agreement much to Ironwoods disapproval.  Y/n jumped off the cliff as Carnage covered his body but his head with the boy swinging from tree to tree. Kneeling down Y/n found blood on the floor dipping his hands in it his tounge grew long like Carnage as he tasted it. As if he was a bloodhound the boy picked up the taste and to where it lea-

"Did you just lick blood?" The symbiote asked.

"Yeah so?"

"There's a trail of it going that way."

"To be fair I used your tongue. Alright let's go."  Y/n activated his weapons inside carnage making the symbiote grow three more claws as he swiped down as a red and black portal opened. Shooting his hands through it Y/n felt himself grab something making him plant his feet into the ground as the giant force tried to move forward dragging the boy.

Team RWBY waited for the monsters attack but saw it being held back as black and red strings held it back.

"Those are Carnages' arms!" Blake said as the grimm dragged the arms closer before whipping the boy out of the portal making him fly over him with a him flailing before landing on his head. Y/n smirked as he stood up wiping off the dirt from his body making the girls shocked as they saw him wearing Carnage.

"Hey girls. Miss me?" He questioned before they all smiled. "Carnage. Showtime."

"Yes.hehehahahaha."  the symbiote smiled before going over the boys head as it smiled.

"Would you like to know why you're gonna die?"

The grimm roared at the boy as it rushed at him with the symbiote covered boy doing the same but he was tackled pass them all. Y/n summoned a ball of energy and threw it towards everyone as a portal appeared in front of them. Breaking out of the monster grip, Y/n grabbed the demons horns and wrapped them in his right hand before grabbing a tree and forced it to turn causing it to lose it balance. Y/n landed on the ground safely as he looked at his team.

"Go now!" He yelled causing them all to look at him.

"What about you?" Ruby asked as he smiled.

"I'll be fine. Trust me Carnage and I have been wanting to stretch our legs out a bit." He smiled before a flame whip wrapped around the males waist causing Carnage to scream in agony. Before retreating into Y/ns body.

"Dah shit." He said as the demon pulled him into the forest quickly.

"Y/n!" They yelled as he vanished into the forest. But they heard a roar making them look up into the sky seeing the demon flying up with Y/n holding onto the whip burning himself in the process.

"Hothothothot."

He watched as the demon dive bomb the ground causing him to look down but saw the beast grab his head forcing him infront. 

"Oh shit!" He yelled.

A giant explosion of dirt flew into the air making team RWBY cover themself from the flying dirt.

The demon roared in victory but was pushed back forcefully as Y/ns feet were incase in the symbiote before returning to normal. Y/n jumps to his feet as his wounds begin to heal with him smiling insanely.

"This will be a great fight." Carnage said as it covered half of Y/ns face.

"Yeah. This will be a better fight than those hunters and huntresses." Y/n laughed as his arm reached out for a tree as he ripped it out and threw it at the beast.

The grimm looked at the oncoming object and cut it directly in half but noticed Y/n quickly behind it with an axe hand and cut off the left horn of the beast causing it to scream in pain. Turning around Y/n and Carnage grabbed its tail and hacked it off before jumping onto it and grabbed its wings. The beast roared in pain as Y/n began to pull. Desperately trying to get the boy off of it, the grimm slammed him into a tree, but failed as the pulling kept getting harder. Slowly the wings began to lift up with the skin seeming to stretch before holes began to form. The pulling got worst as the monster felt its bones snap out of place and soon its wings flew off as black dust splattered onto the insane smiling boy.

"This is great. Scream louder. Scream for me!" He demanded before jumping off and grabbed its tail  before using it as a club. "Four!" Swinging the tail the hunter made the grimm fly over the team before a  portal opened and swallowed the grimm. Far into the sky the grimm appeared as it plummets to its death. But a second portal opened with Y/n jumping out as he grabbed the grimm and smiled insanely at it.

"You ready for a grand slam?" He asked as two portals appeared in front and behind the two as they were caught in an endless loop.

Team RWBY watched as a portal appeared infront of the cliffside, suddenly Y/n and the Grimm appeared,slamming into the cliff the two laid in the cliffside. Pulling himself out Carnage repaired all the damage Y/n had sustained before summoning four tendrils and wrapped them around the grimm.

"I'm sure you've seen enough Hentai to know where this is going." Y/n smirked.

"What's hentai yang?" Ruby asked but suddenly the grimm roared in pain before the four tendrils split him in half as Y/n laughed as dust fell onto him.

"Such an interesting grimm." He smiled as he wiped off the dust.

"Indeed such a great sport." Carnage smirked.

Y/n turned around as Carnage vanished allowing him to look at the girls.

"Are you okay?" He asked as Carnage peeled back allowing the team to see his black haired male as he grabbed their weapons.

Team RWBY slowly began to walk to him as they grabbed their weapons.

"So. This is your new bond with Carnage?" Ruby asked as she poked her fingers together.

"Yes. This is something I had to do. If not I would be worst. I'm hoping my episodes will only happen during battle. But I can't promise that." Sighing Y/n felt Carnage enter his body allowing the boy to be in his hospital gown.

"Come on. Let's get back." Looking at the team. "That's if you're able to walk." Extending his right claw he slashed downwards showing three tears in the air before they began to stick to each other causing them to become one whole portal showing beacons medical room. Everyone except for Weiss stood up as Y/n took noticed. "Do you need help?" He asked earning a defiant "hmph" from the heiress causing him to chuckle.

Walking towards the Schnee, he picked her up bridal style earning a small Yelp from the heiress. "You can act like a Tsundere once you're healed up Snowflake." He smiled earning a small blush from Weiss. Taking the team into the portal Y/n and RWBY all appeared in the medical bay as doctors rushed to them and worked on treating their wounds and scolding Y/n for taking off as he wasn't mentally prepared for combat.  Y/n just laughed it off and told them "if he didn't, his team would've died" this brought the doctors to nod as they began to dress the cuts and burns of the team.

The team all had a small conversation with each other just then team JNPR entered the room as Koda rushed in and went to jump on Y/ns bed but was to short as its little head was poking above it and its paws was barely able to touch the mattress. A small whine came from the cub making Y/n chuckled and use Carnage to pick him up. Growling happily Koda sniffed around as he looked at Y/n and sat in front of him as he growled and jumped on Y/ns feet causing the boy to laugh once Koda missed the foot and touched only the bed. But Y/n noticed that the small Ursa cub was wearing the blue scarf that Weiss bought for him. 

"So how are you guys doing?" Jaune asked looking towards team RWBY.

"We're fine. That grimm was something we never seen before so it just caught us off guard." Smiling Ruby replied to Jaune.

"Oh. So who killed it?" Nora asked excitedly as she looked at each one of them. "Did you freeze it and smash it into pieces?" She asked looking at Weiss. " what about using your speed to slice it apart." Moving to Ruby she smiled. "Or did you dog pile it with your clones and went in for the kill." She asked looking at Blake. "Or did you break its legs?" She smirked at Yang but they heard Weiss cough and point towards Y/n as he played with Koda. "Or....torture it until death." She muttered as she felt sick to her stomach as Y/n chuckled.

"If you call ripping the wings off, slicing the horn and tail while also crashing it into a cliff torture. Then yes." Y/n smiled as Koda playfully bit his hand.

Team JNPR stayed quite as Y/n looked away as he was getting stares.

"Look in hindsight it made sense as he almost killed my team. A eye for an eye. I always say." He smiled. "After all............................Somethings are best left to the imagination."

On a building near by Beacon a familiar claw was seen draping over a building. "So Y/n finally bonded with Carnage. Good. The plan is almost complete. Hehahahahahaha."
