Chapter One: Wings

I haven't done a lot of things in my life since I could remember until Nick Fury took me in when I was twelve. My father was a mad scientist, kidnapping and conducting experiments on animals then people. Killing those animals and people until he came up with his own serum for humanity. One that would not only enhance a person's endurance, speed and strength, but awaken certain powers. He decided to test me as his first subject when I was but a child, nine years old. All I remember when he first tied me to a table and stuck me with a purple needle, was pain. Hot searing pain that ran throughout my body for hours, days even.

I remember passing out and dreaming of a time that I was happy and without constant fear or pain. I dreamt of my very much alive, not dead, mother holding me and singing me as I played with the teddy bear she got me. We were in my old room and my father wasn't around. Probably at work or something as I just laid in my beautiful mother's arms. She had dark blond hair with brown eyes, angelic complexion and just... beautiful like an angel.

After a year of being in a coma and feeling painful spasms throughout my body, I woke up with a pair of white wings with black tips on the feathers. I became a freak of nature and had to never leave my father's basement. But I became stronger, faster, and my endurance was extraordinary. I could fly too and my wings were indestructible. Which I found out when I tried to cut off my wings a few months after I woken up from the coma, but everything broke on me. I couldn't get rid of my wings. And that wasn't the only thing that changed for me. My eyes went from doe, brown eyes to doe, purple eyes. I was a freak.

My father tried to experiment on me and recreate his serum, but he failed every time. He stuck me with needles to draw blood and he went even more mad, almost trying to kill me. But he kept kidnapping people and doing experiments on them to see if the serum would work again, but he was unlucky as they either exploded or it would turn their insides to acid.

His experiments couldn't last forever though as SHIELD caught onto him and his unethical experiments on humanity and his daughter. He shot himself in the head when I was twelve and before they could get to this work, he burned it all. I was hiding in a closet when Fury found me, taking pity on me and brought me to SHIELD. I was free, but at the same time... I wasn't free enough to leave until I turned eighteen.

I was homeschooled and trained by Natasha Romanoff and Clint Barton, aka Black Widow and Hawkeye. I learned that I could shoot out of my hands light, pure energy, and heal others through touch. I didn't start going on assignments til I was seventeen, fighting and saving people though. But once I hit eighteen... I decided to stay at SHIELD as I was too afraid to leave and be in a normal world. Besides I never thought the world would accept a freak like me.

Currently, I was in my room at SHIELD headquarters and playing my guitar. I was trying to just do something with my spare time that I rarely get since I'm usually on missions, but I decided to finally tell Fury that I need less missions to recover from them. The last one was harsh as I had to save the president's six year old daughter from terrorists, but I watched as a young guard was killed in front of me and the young girl. After that incident, I've been avoiding missions since then as that was the first person I couldn't save in two years.

"Agent Hart," Fury says, knocking on my door and I look up from my guitar and nod my head at him to come in. He complies and shuts my door behind him before he walks over and silently sits next to me on the bed.

"I'm still taking a break, Fury. I... I need to process," I said, avoiding his gaze as he sighed and nodded his head.

"That little girl wouldn't be alive or unharmed if it wasn't for you... Angel," He said with a slight smile and I sigh, shaking my head as I frown. He rarely ever calls me by my first name unless it's something of extreme importance. "But I'm afraid the world needs you."

"The world won't accept me," I said, strumming my guitar as I try to ignore his stare. "Remember last time the public saw me? They were afraid of me."

After a long moment of silence, Fury finally speaks, looking straight ahead at my uniform as I watch him. "Maybe the world needs to see the real you in order to overcome their fear of the unknown. And you might not know this, but the world is about to become a war ground. They need you...Barton needs you too."

"Clint?"

"He's been compromised and we have no idea how to get him out of it nor his location," Fury says and I nod my head, understanding that this is above myself.

"Okay."

I was standing next to Nat while we wait for Captain America, Steve Rogers, to come aboard and get over with introductions. I was really excited and nervous to actually meet the first superhero since Coulson and I both share the level of admiration for the old hero. Although mine was more of a crush, making me very nervous indeed as I couldn't hide my anxiety from it. I took a deep breath in and out, trying to avoid seeing Nat's smirking face. She knew of my crush as she saw my poster of him on my wall at fifteen. I've never lived it down since and been avoiding the places the old hero goes to in order to not have a meltdown. Now it's unavoidable, but I gotta do this for Clint.

I almost bolt as Nat holds my arm as the jet lands and a minute later, out comes Phil and Steve Rogers. I try to straighten myself and look mature as he walks over with Phil leading. "Agent Hart, Agent Romanoff, Captain Rogers," Phil says, introducing us as Steve stares at my wings for the first time and I try to hold back my frown before his blue eyes land on my violet ones.

"Ma'am," Steve says to Nat and I, shaking her hand first. He goes to shake my hand and I put my shaky hand in his. I let go after a bit noticing him glancing back to my wings before giving me a small smile.

"Hi." Nat looks at Coulson before nodding her head over to the other agents. "They need you on the bridge. They're starting the face-trace. He nodded and said, "See you there." He walks away, leaving Steve with Natasha and I, as we start walking towards the railing of the Helicarrier. I hug myself as we walk by the edge, wanting to go for a fly. But I didn't want to freak Steve out anymore than he probably already is. "It was quite the buzz around here, finding you in the ice. I thought Coulson was gonna swoon. Did he ask you to sign his Captain America trading cards yet?"

"Trading cards?" Steve asks and I chuckle before I could stop myself, looking down at the ocean.

Nat nods her head and says, "They're vintage, he's very proud."

I look over to see Bruce Banner walking around the ship, trying to stay out of the way while people walk in his way. I remember reading and watching his file and seeing his Hulk form. The doctor walks over to us, looking at my wings with wonder before saying, "Wow. That's incredible. Are-"

"I'm going for a fly," I interrupted, not wanting to answer or talk to anyone now. I hate when new people gawk and stare at my wings and eyes. Nat was about to speak, but before she could say anything, I took a step back and shoot up to the sky.
