AN: If it isn't known that I don't own Marvel or Captain America or Bucky then let it be known now!

This story is for entertainment purposes only. I won't repeat this in every chapter because it really should be obvious.

This story will incorporate gore, torture, smut, some fluff, and anything else that might be triggering to someone. If that's not your jam, DON'T READ!

"Cause I'm with you to the end of the line."

Something inside the soldier snapped at those words. He knew them, he knew the man that fell into the water. He didn't know how he did but he knew him. He looked down at Captain America after having rescued him from the river.

Steve.

That is the name that kept repeating in his head. No amount of thinking could get the soldier to place where he knew this man from though. The soldier watched as Steve took a few breathes of air. He couldn't stick around here. He had to get moving, he had not completed his mission. HYDRA would most definitely be after him soon enough.

A few hours later.

The soldier had gathered supplies already and gotten far enough away from the city before hunkering down in an abandoned barn. He had stolen most of what he needed in a tiny black backpack that would suffice for now. He had a few guns strapped to himself in an inconspicuous manner. He sat staring at the wall like it was the most interesting thing in the universe. Flashes of another time went through his head.

A scrawny kid stood in front of him; blonde hair, blue eyes. He looked sickly and much shorter than him. He was saying something to him. The words came out all muffled, like cotton was in the soldier's ears.

The soldier's eyes closed angrily. He knew that man! HE KNEW HIM… but his mind refused to place him. His head hit the barn wall in frustration as his mind raced.

Gun metal blue eyes opened once again. What was the name Captain America called him again?

James Buchanan Barnes.

It was easy for him. It was always easy for him. He could disappear within an instant but be in plain sight. Like a wolf in sheep's clothing. The years of training with HYRDA hadn't left him and he gathered it never would. He had stolen some clothing and a hat. He made sure the clothes would cover his metal arm. He wasn't interested in drawing attention to himself. No, not now. Not ever again.

The soldier made his way up the museum steps. This is where the display was, where he was, where James Buchanan Barnes was. He navigated the place with ease, it was later in the evening time close to closing. Anyone around was far too invested in the exhibits to really pay attention to him.

He stopped at a screen with an old video playing on it. He watched as Captain America came out of a boat with soldiers rallying around him. The video looped through a few other images as well, which included fights and such. The next display he went to had a large image with Captain America and his elite forces. Recognition registered across his face, he saw his own visage next to Captain America. It felt bizarre to him, he looked stoic and young.

The soldier moved on. The next display he came across was of the Captain himself. He listened to the digital tour guide as it went through everything about Steve Rogers and how he came to be Captain America.

Steve Rogers.

The soldier became slightly disturbed by how he knew this man but couldn't correctly remember him. Steve had mentioned that they grew up together. He knew that somehow, he knew it while he was punching his face in but was far too brainwashed to really stop himself.

The soldier had a duty and it needed to be fulfilled at the time. It wasn't until Steve said those lines to him that made him really snap.

He turned only to be met with a glass wall of himself. A picture of him in the middle of it.

"Best friends since childhood, Bucky Barnes and Steven Rogers were inseparable in both school yard and battle field. Barnes is the only Howling Commando to give his life…."

Whatever words came after that were lost on the man standing before the exhibit. His hands tightened into first, jaw clenched. He felt his control slipping slightly.

Time to leave.

The cage was small, small enough for whatever was in it to not be able to stand. The two-inch spacing in the thick bars the thick cement slabs that lined the top and bottom made it so the thing inside couldn't break through it. This smaller cage was inside of a larger cell with thick walls and a heavy iron door. All along the walls of the cell were deep claw marks. A single light hung from the ceiling of the main cell to illuminate the cage. No light entered the cage however. Only a silhouette of what was inside could be seen. A small security camera in the back-left corner had its lens diligently watching the small cage.

Precautions were very meticulously taken by the HYDRA scientists for the beast that lay inside. Too many times did they make the mistake of underestimating the beast, too many lives lost because of that underestimation. While they did have it under control most of the time with serums and sedatives, the beast would eventually get used to it. Its body adapted quite impressively. Making this creation of theirs the most dangerous.

Of course, this thing wasn't used like the other soldiers they had. No, in fact it was only used on very special occasions. Occasions where agents or soldiers needed to be eliminated, and in the most spectacular of ways. This thing wasn't meant to be precise or clean like their other soldiers were.

The beast was meant to make a statement, a very bloody statement.

Wolfgang Richter was staring at the security monitor that housed his most prized creature. So many attempts, so many subjects lost to the strain and torment that came with his experiments.

This one though was his finest achievement, mind you not without great cost to himself of course. He now had a prosthetic on his right hand. He had once tried to touch the beast, he was mesmerized by it. Not one of his brightest moments, though those mistakes were far and few between.

The doctor was broken from his train of thought by a red phone ringing. He eyed the device as he stalked over to it. He answered it, a voice relaying its message to the doctor, a grin slowly crept up onto his face. He hung up the phone quickly and made his way down, with guards to his left and right, to where the cell with his beast lay.

The elderly scientist opened the cell only to be met with a very low murderous growl. The doctor didn't hesitate with stepping into the cell. The thing couldn't get through the cage. A thick German accent rang through the air "Now, now. Are you going to misbehave already?" The doctor confidently walked around the cage in the middle of the cell. "A soldier has decided to leave our organization through choice, not by death. You are to find him and, well, you know the rest."

A vicious snarl rang out from the cage, it rattled slightly as the beast rumbled in defiance. This made Richter's smirk faltered only slightly. "I thought you might say that." The man reached into his pocket taking out a small device. It looked as if to be a tiny remote control. He pressed a button.

The sound coming out of the cage was earthshattering. No man or beast alive could make that sound. The pure agony and rage shook the cage as the beast inside was tortured into compliance. Richter sighed. They had been through this dance since 1979 and there was always a slight pain the older man felt when the beast wouldn't comply. He didn't care to agonize the creature but it was necessary. The thing constantly fought to regain control, even though it was futile. The collar that surrounded the beast's neck saw to that.

Richter stood with his eyes closed listening to the beast give its last few snarls and growls of struggle before silence enveloped the cell. The scientist opened his eyes and looked to three of the guards that came with him, nodding for them to open the cage. Two of the guards stood at the ready with their weapons trained on the cage, while the third went to open it.

Richter grinned as his creation slowly came out. It stood with its eyes cast down to the floor. Perfect. "Ah, glad to see you have decided to join us, my pet." The man slowly walked to the front of the beast "As I was saying earlier, you will be going on a special assignment."

"You will be hunting and killing James Buchanan Barnes."

AN:

Boy, oh Boy! I've recently caught up on my Marvel Cinema Universe as I'm looking forward to Avengers: Infinity War and I couldn't help but have my eye catch a certain Winter Soldier.

There are a few fics I've seen with Bucky in them and well, I wanted to give it a shot as well.

If it isn't obvious, this is an AU story set just at the end of Winter Soldier where Bucky goes rogue. This story incorporates mutant abilities as well (you'll learn more about my character as the story goes on especially in the next chapter) and some horror creature elements.

Reviews are welcome! Keep it respectful though.

Hope you enjoy!
