Subject Name: Ruby Uraraka.

Experiment: Project Nephilim.

Parameters: Give a person a powerful Quirk, help them train their body, and then have them take All Might's place. 

Effects: Project Nephilim gives the user large black wings, and increases their strength tenfold. Feathers can be fired from the wings like darts, and have been noted to punch through steel blast doors with little effort. User's eyes turn pure black, and an odd green-blue glow has been observed from the user's chest, above the heart. Source is unknown. User has also been seen shadow-hopping. (Teleporting from shadow to shadow.) 

Physical Changes: None.

Mental Changes: User's personality changes dramatically, going from one end of the spectrum to the other. Current subject was cheerful, smiled often, and made quick friends with researchers. (All of which will be terminated at a later date.) Now, subject rarely smiles, refuses to leave their cell except for tests, stating "I want this to be done so I can go back to sleep." Subject has been observed sobbing loudly at night, dragging their nails across their skin. When asked why, the subject glared at the researcher until they left. 

Internal Changes: Bodily fluids maintain a normal temperature, the exception being tears. These boil as they leave the eyes, and apparently freeze as well, leaving burns and deep scratches. Subject hides these with makeup. 

Additional Information: Subject has been observed breaking her own bones, then watching them slide back into place, then breaking them again. When asked why, no response was given. For a time, subject was observed ripping their wings off their back, with the help of another subject, the other subject being T-1571 (She refers to herself as [Redacted])

Original Quirk: Zero Gravity.

Ruby POV

"OK, X-483, you can come out now." O'Brian said. "Her name is Ruby." A woman snapped. "Right, sorry. Miss Uraraka, please, come see your family. You're free to leave." He said. I stood abruptly. The other children sighed. "It's fine. I'll probably be back here in a week, guys." I whispered, slowly walking to the door. The light was too bright. Everything to bright, too colorful. "Ruby, oh my baby." The woman gushed, grabbing me in a tight hug. "Ruby may not be the same, Mrs. Uraraka. We've done nothing to her mind, but the Quirk we gave her seems to have changed her personality." O'Brian said. The woman shook her head. "As long as I have my baby back, I'm fine." The woman said, before taking my hand. 

3 hours later...

"Mom?!? Dad?!? What are you two doing here!?!" A girl exclaimed. I covered my ears. "You're too loud..." I whispered. "Hey, sweetie, we have a surprise for you!" Mom said. "Hey, Ruby? Come here, please." Dad said. I slowly and silently walked down the hall, and vanished. I reappeared behind the girl at the door. "You're really loud." I whispered in her ear. 

Ochako POV

"You're too loud." Someone whispered in my ear, causing me to shriek in alarm and fall over. When I finally spotted the person, she was crouched on the floor, holding her ears with a pained expression. "W-who are you?" I stuttered. "I'm Ruby, your sister." She said, pulling her hands away from her ears, and checking them. When she looked at her hands, I saw blood. "Y-you're bleeding!" I exclaimed, causing the girl to cringe. "Please be quieter. My ears are literally bleeding." Ruby whispered, taking a tissue and cleaning her ears of blood. 

"I'm sorry, Ruby." I whispered. "It's fine," She replied. "But be quieter. The doctors said it'd take a couple days for my ears to adjust." I nodded. "OK. Will you be coming to school with me?" I asked. Ruby nodded, then stood. "I'm going to bed," She announced quietly, before silently sauntering off. 

Mom sighed, and she walked after Ruby. Shortly after, Mom walked back out. "She's very adamant about sleeping," Mom said. 

1 week later, Ruby POV

"This uniform is too tight," I grumbled. "Where?" Ochako asked. "Around my chest." Ochako giggled. "Yeah, I had that. We'll get it fixed later. Oh, word of advice? Avoid the purple haired boy. He's a major pervert." I nodded. "OK." I replied. "And don't make Bakugou kill you." She continued. "Violence? My favorite thing." I rolled my eyes. 

"Have a good day at school, girls!" Mom shouted as we left. "Will do!" Ochako shouted back. "Will this shirt even work with Project Nephilim?" I wondered aloud. "Hmm?" Ochako replied. "O-oh, nothing." I stuttered. "Nervous?" My sister asked. "No. Bored." I grumbled. Suddenly, Ochako gasped. "Deku!!!" She squealed. I tensed up, and I dropped into a combat stance. "Trouble?" I hissed. Ochako looked at me like I'd gone insane. "No, doofus. He's my friend. His name's Midoriya." I relaxed. 

"Uraraka!" A boy shouted. Both my sister and I turned. "Yes?" We asked in unison. The boy stopped. He had green hair, but that was really the only notable fact about him. "Midoriya, I presume?" I asked. He nodded slowly. "Hi Deku!" Ochako was blushing. I sidled up really close to her. "You like him? He's so....plain!" I hissed. Ochako glared at me. "Uhhh... Uraraka, who's this?" Midoriya asked. "This is my sister, Uraraka Ruby." Ochako said. I bowed. 

(It was around this time that I decided to put my cat inside my sweater whilst I was wearing it. He is not very happy.) 

"H-hi. I'm Midoriya Izuku, but Uraraka and Kacchan call me Deku." The boy said nervously. "Pleasure to meet you." I said flatly, before looking away and walking off. "She's....nice?" Midoriya said. "She's like this at home. I think she likes you, platonically, at least. She rarely talks to people." Ochako said. Midoriya blushed. "But! She's still my sister, and if you wanna date her, you gotta go through me!" She said. I cracked a tiny grin, then warped behind her. "That so, Ochako?" I whispered in her ear, causing her to jump and tackle Midoriya. I then bowed once again and continued walking to school. 

30 minutes later...

"We have a new student. Show her the same respect you show each other." A tired, scruffy looking man said. Then, he turned to me. "My name is Aizawa. You'll sit in the back," He muttered, and I nodded. As I approached the back of the room, I heard a boy muttering something about a perverted fantasy. I turned and glared at a purple haired... I don't know. Mutant grape? Gremlin?

He went silent. 

I rolled my eyes and took my seat, and a couple hours went by before Aizawa told us to get into our uniforms and head out to Site Gamma. I sighed, and left the room with everyone else.
