RWBY: Oscar the gamer

It was the dead of the night, as shadow moved to the halls of Beacon Academy, they left the door and made there way to the emerald forest, they ran avoiding all the camera before arriving in a place with out any Camera, this was non other then Oscar

Oscar just sighed as he pulled out the dungeon key. "Let's see what monster/Grimm are in this one".

[ Host this place has no camera, and be careful your only level 23 ]

Oscar just looked the system. "Will I am doing this to get my Grimm Human Hybrid transformation".

He twisted the key, as a blue portal opens he walked in, and will it was beg Oscar think it will take me 2 - 3 hourse to clear the Dungeon, 2 hourse if pushed his [Agility Skill] to the highest.

Oscar looked around pulling out Midnight Fang. "Alright let's see".

He actived his [stealth skill], as he looked around for the first monster and there he found, it was Grimm but they look different, as they look Human and not only that they looked like Goblins as well, in a way they were a fusion between Goblin, Humans and Grimm.

Oscar just looked at the monster. "Will this is definitely new"

The creature stood hunched over, its body a twisted amalgamation of human features and Grimm characteristics. Its blackened skin was marred with red cracks that glowed faintly in the darkness, while its eyes burned an eerie crimson. Its limbs were long and gnarled, with clawed fingers that twitched as it moved. It growled lowly, sniffing the air as if it could sense Oscar's presence.

Oscar crouched low, his grip tightening on Midnight Fang. "Goblin-Grimm hybrids? Looks like the dungeon's stepping up its game."

[ Host, be cautious. These creatures are Level 20 and higher. Their behavior indicates heightened intelligence. ]

Oscar activated [Stealth Skill], moving silently along the edge of the area. His eyes scanned the surroundings, noting the positions of at least three more hybrids lurking in the shadows.

"Alright," he whispered to himself, "one at a time. Don't draw unnecessary attention."

He waited until one of the hybrids strayed from the group, isolating itself as it inspected the remains of a broken tree. With a deep breath, Oscar activated [Critical Strike] and dashed forward, slashing at the creature's exposed back with Midnight Fang.

The hybrid let out a guttural scream, black smoke billowing from the wound as it disintegrated.

[ Host has defeated a Level 20 Goblin-Grimm. +500 XP earned. ]

Before he could celebrate, the remaining hybrids turned, their crimson eyes locking onto him.

"Of course," Oscar muttered, gripping his weapon tightly.

The hybrids charged, their movements erratic but coordinated. Oscar rolled to the side, avoiding a swipe from one's claws, and slashed upward, cutting through another's torso.

[ Host has defeated a Level 21 Goblin-Grimm. +550 XP earned. ]

One of the creatures leaped at him, its claws aiming for his throat. Oscar quickly activated [Agility Boost], narrowly dodging the attack and countering with a stab to its chest.

[ Host has defeated a Level 22 Goblin-Grimm. +600 XP earned. ]

Breathing heavily, Oscar stood amidst the fading smoke of his fallen enemies. "This is tougher than I thought."

[ Host has unlocked progress toward Grimm Hybrid Transformation. Defeat more hybrids to reach full mastery. ]

Oscar smirked. "Alright then. Let's see what else this dungeon has to offer."

He ventured deeper into the dungeon, his mind focused and ready for whatever twisted challenges lay ahead.

Oscar then sighed as he looked at the system. "Activated it"

[ You don't need to say it host, but anyway, Activated Grimm Human Hybrid transformation]

As then a blast of energy came out of Oscar and will it hurt to say the less, he screamed as his body was turned pure black, his clothes fused with his body, as then two wings came out of his back, as his feet was covered by bone like armour, as so did his hands and finger which now had claws, his face has a broken Grimm mask as he has red eyes, a tail came our of his back which had spiked.

Oscar took a deep breath as abs spoke. "Ok that hurt, it fucking hurt, how to I look".

He pulled out an mirror from his Inventory, that he stole from Weiss and took a look at him, he almost didn't recognise him if was different from what he thought he thought white skin, red marking and so on

[ Incomplete Grimm Human Hybrid transformation has been activated, current Level 5 ]

Oscar looked at his reflection in the mirror, taking in his new form. His once-familiar features were now twisted, a blend of human and Grimm traits. The blackened armor-like skin gleamed faintly in the dim dungeon light, the bone-like structures on his hands and feet giving him a menacing aura. The jagged Grimm mask covering part of his face seemed almost alive, as if pulsating with dark energy. His red eyes glowed fiercely, and the spiked tail swayed behind him, adding to his intimidating presence.

"Damn," Oscar muttered, his voice carrying a distorted echo. "This is... something else."

[ Host, this transformation is incomplete. Its power will increase as you level it up. Current enhancements include: Strength +20%, Speed +15%, Regeneration +10%. Be cautious—prolonged use may cause strain on your body. ]

Oscar flexed his claws experimentally, feeling the sharpness in each swipe. He spread his wings wide, marveling at their span and the slight hum of energy coursing through them. "Alright, System. What's the catch? There's always a catch."

[ Prolonged use increases aggression. Self-control and focus are critical. Failure to manage emotions may result in a loss of control. ]

Oscar sighed, pinching the bridge of his nose—or at least where it used to be under the mask. "Figures. Alright, I'll manage. Let's test this out."

He moved deeper into the dungeon, his enhanced senses picking up faint movements ahead. The Goblin-Grimm hybrids he had fought earlier were nothing compared to the hulking figure that emerged from the shadows now.

It was a massive Grimm with human-like features but far more grotesque—a fusion of an ogre and a Beowolf, standing at least ten feet tall. Its claws were as long as swords, and its jagged teeth gleamed as it growled.

Oscar grinned, his voice tinged with excitement. "Perfect. Time for a test run."

He lunged forward, his wings propelling him faster than ever before. The ogre-like Grimm swung its massive arm, but Oscar ducked under it with ease, his claws raking across its side. The creature howled in pain, black smoke rising from the wound.

"Not bad," Oscar muttered, landing gracefully and preparing for another strike.

The fight was brutal but exhilarating. Oscar's newfound strength and speed allowed him to dodge and counter with precision, his claws tearing through the Grimm's tough hide. The tail proved useful for tripping the beast, and his regeneration kicked in when it managed to land a hit.

Finally, with a powerful upward slash, Oscar struck the creature's core, causing it to disintegrate into smoke. He stood there, breathing heavily, but with a triumphant grin on his face.

[ Host has defeated a Level 30 Ogre-Grimm Hybrid. +1,500 XP earned. Grimm Hybrid Transformation has leveled up to Level 6. ]

Oscar stretched, feeling the energy surging through his body. "Alright. I could get used to this."

[ Reminder: Monitor your aggression levels, Host. ]

"Yeah, yeah, I've got it." He dismissed the system's warning and looked around. "Let's see what else this dungeon has for me." With that, he moved forward, ready for the next challenge.

Oscar then untransformed, and he felt more in his skin, but he heard a laugh, he looked around but noting was there, he thought it was a mind trick, then on the ground was the broken Grimm mask, as he looked at as the item box came up

[ Broke Grimm mask, this is the Grimm mask in the use of the Grimm Human Hybrid transformation, the mask will be more broke the more the form is leveled up, the mask will be used to transform ]

Oscar puts the mask in his inventory. "Will now, system show me my current stats and will everything".

Aggression Control Needed: High ]

Oscar reviewed the stats, nodding to himself. "Looks like I'm making progress. Grimm Hybrid transformation is turning out to be a powerhouse, but I'll need to manage the aggression issue."

Oscar sighed, leaning back against a tree as he reviewed his stats and inventory. "Alright, not bad. I'm getting stronger, but I need to keep this transformation under control. No point in going berserk mid-battle and turning into a liability."

The broken Grimm mask caught his attention again. He took it out of his inventory, holding it up to the moonlight. The jagged edges of the mask gleamed faintly, and for a moment, he thought he saw something flicker across its surface—a fleeting image of red eyes and a sinister grin.

"Yeah, you're creepy as hell," Oscar muttered, tossing the mask back into his inventory. "But you're part of the package, so I'll deal with you."

He stood up, stretching as he took a final look around the now-cleared dungeon. The eerie quiet of the forest was settling back in, and the portal behind him began to shimmer and close.

[ Dungeon Cleared. Rewards: 1,500 XP, Dungeon Key (Used), +5 Stat Points. ]

"Good haul," Oscar said, pulling up his stats again to allocate his new points. After some thought, he distributed them:

Strength: +2

Endurance: +2

Charisma: +1

"Need to balance power and stamina. Charisma might help keep me from looking like a total lunatic when I have to explain my transformations," he reasoned.

[ Stats Updated. ]

With everything sorted, Oscar turned and began heading back to Beacon Academy. The journey was uneventful, the chill night air helping to calm his nerves after the intense dungeon fight. As he neared the school grounds, he activated his Stealth skill to avoid being spotted. The last thing he needed was an interrogation about why he'd been out in the forest at night.

Once safely inside his dorm, Oscar collapsed onto his bed, exhausted but satisfied. "Alright, system," he murmured, his voice heavy with sleep. "Tomorrow, we figure out how to deal with this aggression problem. For now... goodnight."

And with that, he drifted off, the broken Grimm mask lying dormant in his inventory, waiting for its next use.

He left the dungeon, the boos for this one was easy, and sure it was good rest of his new transformation but he still remembers that laugh, he then looked at the rising sun and the time it was 6, when he normally wakes up or will now he does thank to this system

So he went back to beacon, did is daily Quest, of 10k Run, 100 push up and 100 sit up, he noticed he went over board but it kept track decided to test it out of went up, now he did a 20k run, 200 push ups and 200 sit ups, which he raised and eyebrows at as for now he got more +1 to his stamina, Strk and agility he will check it out later.

He then went back to his dorm room, ready to take a shower he was sweating he meet with Pyrrha long the way they had a small chat, he checked the time it was 8, he should get to making lunch for the team, so he went to the bathroom but something just felt oof to say the less, and that he noticed someone was not sleeping he didn't know who maybe Yang woke up early.

Oh he wishes, he opened the door and his face red, as the standing in the mirror, with a towel on was Ruby Rose, she has water dripping down from her body, the total was hugging her body which showed of her curves which not Yang level was still impressive, the bellow part of the towel which was covering her but was not doing a good job, as it was up a bit as Oscar can clearly see her ass in full view, and will it was something she was caked up that is for sure, her fair skin kinda shines in the water that was dropping done, hee hair was wet and sticking down.

Oscar had only opened the door by a bit, so she didn't noticed him but why was she up so early today, it was weekend, he close the door and went to his bed and went a sleep.

Few minutes later Ruby walked out for dresses, she said something about Nightmare as she left probably to the training room, as then Oscar went to the bathroom he definitely had a Boner after seeingt and will.... He fixed with some help of his hand.

After taking a shower he would definitely not look at ruby the same way ever again, and hopefully she never noticed him.

2 hourse later.

Blake walked into the kitchen she had freshen up, as she saw Oscar making an ungodly amour do Pancakes. "Um Oscar are you ok".

Oscar snapped his neck and looked back at his partner as he spoke way to quickly. "Yeah I am perfectly ok noting happened".

Blake raised an eyebrow at Oscar's response, crossing her arms as she leaned against the counter. "Right... because making this many pancakes at once is totally normal," she said, gesturing at the towering stacks of colorful pancakes.

Oscar turned back to his cooking, flipping another pancake onto the pile. "I'm just... trying to be a good teammate. Breakfast is important, right?"

Blake narrowed her eyes but decided not to push further. "Well, if you say so. But if you're using this as a coping mechanism, maybe tone it down. We're going to have leftovers for weeks."

Oscar chuckled nervously, avoiding eye contact. "Noted."

Soon, the rest of the team began to trickle into the kitchen. Ruby was the first, yawning and rubbing her eyes as she sniffed the air. "Is that... pancakes?" she asked, her eyes lighting up as she saw the stacks on the table. "Whoa! This is amazing, Oscar!"

"Yeah," Yang said as she entered, stretching her arms. "You've outdone yourself, farm boy. Did you even sleep last night?"

Oscar froze for a moment but quickly recovered. "Of course I did! Just... woke up early to get a head start on breakfast. Nothing weird about that."

Weiss followed next, raising an eyebrow at the colorful pancakes. "You even color-coded them? How... meticulous."

Oscar cleared his throat. "It just felt right. Red for Ruby, yellow for Yang, black for Blake, white for you, and, uh, green for me."

The team stared at him for a moment before Yang smirked. "Green, huh? Feeling a little envious this morning, Oscar?"

Ruby, oblivious to the implication, picked up her stack of red pancakes. "Well, I think it's sweet! Thanks, Oscar."

Oscar gave a tight-lipped smile, keeping his gaze firmly on the stove. "No problem. Just eat up, everyone."

As the team dug into the pancakes, Oscar silently vowed to never open the bathroom door without knocking again.
