Consumer of All (Morphing reader x RWBY)

Epic Crossover Moment

Y/N's eyes burst open. He sat up and looked around. "Where am I?!"

It took him a second to register and remember what happened before. He fought a massive amount of Grimm and ended up eating some gore of an Alpha Beowolf. He laid back down as the scene of the clinic appeared in his memory, helping him calm down. Yet...

He was nude aside from his underwear for some reason. His body was still very hot, but instead of the itchy sensation he felt ticklish. He sat up again to examine his body, confused. Then he saw it. 

On his arms, legs, and chest, his body hair multiplied. It almost looked like he had white fur. Then his noticed how in his hands, his previously blue veins were black. He found his boxers were also tighter than before. Did he grow? Even more, his nails seemed to have grown into short claws. His teeth grew a bit longer and sharper. He felt his head with his hands and found his ears were long and pointed. His hair was still short though, much to his relief. 

"Is everything alright?!" A meek yet beautiful white-haired woman entered the clinic from another room. She saw that Y/N was awake and was in shock. She gulped nervously. "Oh, um... I promise I did nothing to you but give you that elixir yesterday... I hope you're not upset."

"..." Y/N's irises, which had become a brilliant gold, bore into her very being. It was as if he could see through her clothes, her flesh, and view her soul itself. 

It was unnerving but also somehow riveting. She felt a slight urge to get more of his attention... but why? What was happening to her? Were his changes releasing some kind of pheromone?

The answer to that was yes. Y/N was already an alpha male carnivorous faunus. He was seen this way only by other faunus, though. After waking up, his body released pheromones that attracted the opposite sex, faunus and human alike. This was the Alpha Beowolf's genes coming into play. As the one who laid claim to any and all mates, he had to make his identity known. 

"...Hello? You there?" Y/N's voice jarred Jeanne from her thoughts.

"Ah! Sorry, I was just surprised..." She said sheepishly. Y/N got off the bed and stretched, making her anxious. "Wait! You could still be hurt!"

"I feel the opposite..." Y/N cracked his neck and knuckles, then looked at her suspiciously. "I've never been so full of power. What exactly did you do to me? Was there a side effect in the elixir?"

"Um..." Jeanne herself had no clue. The red rose extract should have no side effect at all. However, the yellow dust she used to empower it so it could overcome the Grimm essence may have done something. She had to test it. "I'm not entirely sure. I've never seen this before. Your body is so... unique."

Y/N stood 6' 4" and was still very robust. His face seemed bestial, but in a regal way. Like a proud lion, albeit he strongly resembled a wolf. He radiated a sense of superiority, like an alpha of a pack. This gave Jeanne an idea. "Are you related to any wolf faunus?"

"My dad was one, and I am one too. Why? You think my heritage is to blame?"

"I wouldn't phrase it so harshly, but it is very possible. Your wolf faunus genes mixing with the Alpha Beowolf genes could've inspired a mutation in your DNA as you healed, thus changing your body to what it is."

"Huh," Y/N scratched his chin. Her words made enough sense, but it was still weird. Was this phenomenon related to his semblance? He needed more information. "Do you have a mirror?"

Jeanne led him into her bathroom so he could examine his body. He was stunned by his hairy visage, but it could be worse. He could use his semblance to make his body hair fall off, but that would be a mess to do here.
