Chapter 1

A dark crimson haired woman was woken up to a bright light being shined in her eyes. As she woke up, she saw that there were a few men standing around her with clipboards and wearing white jackets. Before she could see anything else though, her attention was brought to the man in front of her. He was saying something before they injected something into her arm.

Once the drug took effect, everything seemed to be blurred, and all she could hear was 'You serve HYDRA.' Being repeated over and over again. And eventually, after who knows how long, she believed it. It became a permanent feature in her mind, she followed the voice's directions. HYDRA trained her for years, teaching all the strengths and weaknesses of different types and styles of combat, intellectual, physical and psychological. She was taught to use anything and everything she had at her disposal to kill her targets, though they had avoided any actual sexual training seeing as she reacted violently when they tried. They encased her arms in a layer of the same vibranium/ adamantium alloy as Captain America's shield, coming across the formula for it after killing Howard Stark and his wife. They couldn't make much, seeing as they didn't have much of either Adamantium or Vibranium, both being such rare metals, so they hadn't been able to make the Winter Soldier's arm out of the metal. Just coating the Summer Soldier's arms though, they had just enough to completely cover them.

Later, it was established that she would be their second Asset. She was to be called the Summer Soldier, seeing as she had curly dark crimson hair that gradually got lighter at the bottom and her bright emerald eyes. She was taught to use several guns, daggers, knives, and other blades. No matter how long they tried to brainwash her though, they never truly broke her. They found that they were never able to wipe her after a mission, so they didn't. They found that they had no need to freeze her, since she didn't age as far as they could tell, but over time they had found that she was just aging at a much slower rate than normal people and believed that it was because the X-gene had activated in her, giving her better strength. She later became even more hidden than the Winter Soldier, only doing the quietest jobs that weren't discovered until days, sometimes weeks, after they happened.

It was on a job a few years after she had been fully trained when she met the Winter Soldier. They were supposed to be working together to kill an agent of an organisation called SHIELD. They were going to have to enter a SHIELD base to kill the scientist seeing as she never let, and so the Summer and Winter soldiers would go in and kill them, then get out unnoticed.

As they prepped the Winter Soldier, the Summer Soldier watched, sitting near the exit point. She watched as they assembled all his gear, how he was taken out of ice, how he seemed to be just a doll, not even truly eating before the mission like she had. They didn't do anything other than give orders to the Summer Soldier, she healed herself and followed all orders anyway, and she didn't age, they didn't need to do anything to make sure she stayed. There was nothing that they needed to do to her, and because she completed all her orders willingly, she was allowed anything she wanted.

"I am the Summer Soldier, we are to work together to kill Agent Barnaby of SHIELD." She told him once he was fully prepared. "We will be infiltrating the base, I will distract the agents while you quickly kill the target. Understand?" She ordered him monotonously. She hated working with others, they just messed things up.

"I am the Winter Soldier, understood." The Asset replied, also monotonous. The HYDRA agents all around them couldn't help but shudder as they watched the two interact. The things each of them accomplished separately was nothing short of amazing, the things those two could accomplish if the worked together… They all shuddered once more.

Once the job was completed, the Summer Soldier followed to where they were taking the Winter Soldier. She hadn't had anything to do, so she just continued when they said that they were doing the standard procedure for the Asset. She didn't understand what they were doing though. "You don't do any of this to me, what's going on?" She asked with a small bit of curiosity in her voice, but mostly commanding as they strapped the Winter Soldier onto the bed. She was allowed to ask questions, though she rarely did. The Winter Soldier looked at her, though his eyes seemed to nearly unnoticeably widen when she stated that they didn't do that to her.

"We are wiping him. It has to be done." One of the scientists told her. They then went back to preparing the machines and strapping him onto the table.

"But none of these things are done to me. Take him off, I don't want him to be frozen." She told them, she walked to the machines and pulled them off of him without permission from the scientists to do so.

The Summer Soldier was just as enhanced as the Winter Soldier, maybe even a little more. She had large, poison green eyes and dark crimson hair. Her face looked aristocratic yet soft, with hair kept in a long french braid that fell to around her waist. She had a curvy body, and she was beautiful, it was a wonder how she managed to keep her virginity all these years. Many times soldiers had tried to take advantage of her, though they had always ended up six feet under while she had kept her chastity.

She had the code for the Winter Soldier, being told that should he be compromised, she was to retrieve him. She was an average height for a woman, maybe a little tall standing at 5' 4", her arms coated in metal. Yes, they were still her arms, but they had been covered in a vibranium-adamantium alloy to allow her to use her arms as weapons, similar to the Winter Soldier but in a more efficient manner seeing as they didn't need to attach the artificial nerves that was required of The Asset's for her, nor did they have to continuously wipe and freeze her seeing as she had been conditioned through brain washing to obey them, as well as she didn't age. Because of this, both of her arms had been covered in the metal, and she had been able to wander the whichever base she was being held in. Seeing as she was the fail-safe for the Asset, she had to be even more powerful than it as well.

"What is your code?" The Asset asked her in a monotonous voice, completely empty yet deep, compelling her to come closer. She didn't.

"Autumn has fallen, Winter is coming." She told him in the same monotone. "Follow me." She told him before turning around and walking towards her rooms.

After that day, they had become close. They were still sent out on missions, but they spent the time they weren't on missions together. Until one day he came back… Different. He seemed more distant, confused even. "What is wrong, beloved?" The Summer Soldier asked as she embraced him. They had grown close in the last few months, she never allowed the scientists to take away her beloved's memories, never allowed them close enough to take his love from her.

"I am leaving." He told her. "This… This is not where I belong." He told her, a slight Brooklyn accent mixed in with his usual Russian one. "On my next mission, I will leave this place, darling. Forever." He told her. She had tears in her eyes, but she knew that this is something that he truly wanted, truly needed. She had seen the looks that the scientists had been giving them lately, they were planning something, something that would likely end up with the perfect little soldier, created from the Summer and Winter Soldiers. So with a kiss, they went to sleep, knowing that this could be the last time they slept together.

'I serve HYDRA. I serve HYDRA.' A voice chanted in her mind, telling her that she must obey HYDRA, that she cannot leave with him, that HYDRA is always right. So as he left for his next mission, she kissed him deeply, knowing that the next time that they met, she would likely have to kill him.

After a few weeks, HYDRA had come to the conclusion that the Asset had betrayed them. They started preparing the Summer Soldier to go after him, feeding her lies and twisted truths to make sure that she would eliminate him should she be unable to bring him back.

They told her things like, 'He never loved you.' 'He was just using you.' 'He left you alone.' 'He lied to you.' The voice in her head just kept repeating these things over and over again, not allowing her any reprieve from their lies. Eventually HYDRA and the voice convinced her that it was true, because HYDRA is always right. So she believed that he had left her, but the effect wasn't exactly what they had planned and/or intended. She blamed HYDRA for him leaving her. She blamed them (quite rightfully) for her beloved using her, for her beloved not loving her.

So, she did what she did best. She destroyed everything and everyone in the base, quietly, unnoticeably. She razed the inside of the base, but the exterior showed nothing of the bloodshed that occurred inside. And it wouldn't be until months later that they would read her note, that they would realize that they had just let the ultimate weapon fall out of their control, that they had made her unstable by convincing her that the only one she loved had lied to her.

After all, Hel hath no fury like a woman scorned.

Dearest HYDRA,

I thank you for the training, even though I hate you. You never did truly figure out why I was spewed out of the staff, did you? I guess that you can't be all knowing. After all, it is quite simple to kill a Hydra, you just need to crush its heart, though I would much prefer ripping out the heart with my bare hands, crushing it, stabbing the remains with several daggers and knives, then setting the thing on fire. Can never be too sure of it being dead under a mountain, after all.

You never seemed to figure I was more than I seemed, never looked any deeper than my strategic ability and high adaptability capabilities. You never seemed to look at why my mind was slightly different the that of a normal human. But I won't tell you, after all; a woman needs to have some secrets.

I am off to go and find my beloved, and if you don't want what has happened in this base to happen to all of your other bases, I suggest you don't try to push me again. I will not be as lenient as I am being now.

Insincerely,

Duchess Hadria Maeve Potter-Black of Britain, also known as the Summer Soldier
